Debbie was wonderful to work with. She was kind, professional and knowledgeable!

Debbie and all of her associates were amazing!!! I had full confidence in them and their system. The installer was great too!!! I would highly recommend them without a doubt!!! My husband has another home and had ADT installed and you can’t even compare Marshall Alarm Systems to ADT. He wishes he had known about Marshall before he called ADT but he will probably be switching over. I’m so thrilled & happy!!

Just a word of appreciation — the folks at Marshall Alarm have provided us with great service. Debbie and the crew are incredibly professional and take their jobs very seriously while still being friendly, and they are a pleasure to interact with. When our fire alarm was accidentally triggered by our contractors, I got to see the speed (in our case within seconds) with which they responded to the alarm, which gave me comfort. I’m very satisfied so far and highly recommend Marshall Alarm as a top-notch local business.

Very good experience. Debbie was responsive to our request for an assessment of our additional security needs. She is competent and reliable. I feel assured that we will be safe in our home with the appropriate alerts to extreme heat and smoke. Thank you!!

Marshall Alarm is first rate. Debbie is a consummate sales professional — punctual and responsive. Rob and Marshall Jr. performed a quick, accurate, meticulous (!) install. Of all the alarm companies I’ve dealt with, Marshall Alarm is the most professional. Their service so far (day 2) has been fantastic. They are also quite knowledgeable and eager to get things done right the first time. They are very friendly and care tremendously about customers and outcomes. One of the best-run businesses I’ve ever come in contact with. If you’re in the area, you’d be crazy not to go with Marshall Alarm Company.

Note I’ve downgraded this. Repeated issues since we had the system installed. ECP errors on all touchpads, continued “fixes” and then issue recurs. Lots of time on my own troubleshooting. Nice folks but the systems need to work. Note they installed this from scratch.

I’ve upgraded to five stars. Were issues with our system but Marshall Alarms worked on it and got it right and offered longer warrantee to boot. Family-owned means a good deal in this industry and this family

Debbie took the time to evaluate our needs and made excellent recommendations. Very professional business with excellent customer service and follow-through. Highly recommend this company.

We recently had a full house alarm installed with Marshall and the entire experience was a pleasure. From meeting with Debbie to go over what was best for our home to the installation with Robert who was thorough, answered all of my questions and explained everything in an easy to understand way, we have been extremely pleased. We not only feel more secure and safe in our home but also know we have the Marshall team there for us at one quick call if we need anything which is very reassuring. Highly recommend this service!
“Janine O’Dowd”

Marshall Alarm came highly recommended. Now that I’m a current customer, I can’t stop raving about their services. From the first phone call and throughout the process, they were professional, knowledgeable, efficient, and responsive. Debbie treated us like a valued customer before we even signed the contract, and she continued to make herself available even after the equipment was installed. The field technicians were punctual, thorough, and made sure that all our questions were addressed. The office staff are also amazing, and it is so refreshing to speak to a live person without a long wait. You won’t find this level of service with any other company.

I chose Marshall Alarms primarily because of their numerous and stellar reviews, which I personally found to all be true. Everyone is professional, friendly, and proactive in getting to know you as a customer and meeting your needs. I immediately felt Debbie’s incredible caring and upbeat energy at the front door, which was then validated when she took as much time as needed to genuinely review my needs, make recommendations, go over pricing (no gouging or up-selling here), and immediately return my calls, texts, or emails. I look forward to having Marshall as my security company for many years to come.

The best thing I have ever done was move my alarm service over to Marshall Alarms Systems. Debbie came out and inspected everything and told me exactly what we needed to do to to switch it over to them. Not only did they convert my alarm system over, they also installed 12+ surveillance cameras around my house along with Co and smoke detectors inside. Everyone is extremely professional and walk you thru exactly what they are going to do. There is no other company like them. Any time I have an issue with anything they come out promptly or walk me through the issue over the phone that is my fault to begin with. Marshall, Debbie, the office staff, everyone at Marshall Alarm Systems is wonderful. I would never use another company. I never knew what feeling safe was until I switched over to them. If I could rate them higher I would! Love them and highly recommend them to everyone. If you want a professional, knowledgeable, and curteous company, then you have found the right company.

March 2023
Spectacular customer and technical services. We recently bought a home and we wanted the best home security system when it comes to service, price and more. I was referred to Marshall alarm company as one of the best local alarm companies in town. I called them and I truly was amazed by their quick response in getting beck to me with all the information I needed. I had a wonderful experience with Debbie. She is the sales coordinator and is one of the best customer service agent you can deal with in terms of accountability and professionalism. She was great through the entire sale process and helping us in getting the best system possible through the entire home. Marshall, the owner of the company, then came at exactly the promised time for the installation. The installation process was great, including setting up in the system and showing us how to use it. Highly recommended!

Debbie is as good as it gets. She went over every detail and answered all my questions. I am very happy having their alarm system in my home.

We just switched to Marshall and I cannot tell you how happy we are with the change. What a change! – No long waits on the phone, caring and knowledgeable help, and even a better selection of equipment to meet our needs. From the first day I contacted Marshall and throughout the instillation process, everything was just right. And on top of great treatment and service, the monthly charges are now half what they were before. Highly recommended!

Debbie, Marshall, and the entire team are nothing short of amazing! Last year, I moved to a new home where I inherited a convoluted system, and it took weeks for the existing company to even call me back for an intro! So I spent the next few months researching and contacting various alarm companies, including Marshall Alarms. During this research phase, I found Debbie to be very knowledgeable, helpful, and incredibly patient with me as I narrowed my choices. I would email, text, and call Debbie at off-hours and she was immediately responsive and helpful in guiding me on alarm systems. She did not try to push me to Marshall Alarms – but simply described the pros/cons of all the various systems, and the many companies servicing them. It was clear to me that Marshall Alarm was the way to go. Even Marshall himself was available and easily accessible to answer my many additional questions, and he was incredibly thorough with his explanations. The install went very smoothly and I was impressed that Marshall was there to make sure everything was up to the high quality standard that they set. I would highly recommend Marshall Alarms for their honesty, integrity, top notch customer service and overall quality of work. Save yourself the months of research I did, go with Marshall!

The whole Marshall team has been great from beginning to end. Debby has been a great resource in assessing our needs and giving us the right solution at a fair price. Customer service has also been extraordinary. I’d highly recommend for anyone in the market for an alarm system

Marshall Alarm is terrific and you will have no regrets choosing them as your alarm company.

Longer review:
I have had a great experience with Marshall Alarm. I recently moved to Westchester and purchased a home that had been serviced by a different alarm company. The system in the home was dated and required some upgrades. The previous company wanted to charge for a tech to come out to assess and upgrade (just the visit, not including the cost of the additional new equipment) their system. To add insult to injury, the company requires an additional $8.95/mo to use their app, on top of their monthly charge. Outrageous. Oh yeah, 5 year contract too.

After extensive research for other alarm company options, I reached out to Marshall, given their good reviews (one other company I contacted said they couldn’t service Honeywell equipment – Marshall didn’t bat an eye).

Marshall have been nothing short of excellent. Debbie, our saleswoman, is extremely knowledgeable, provided great advice, offered recommendations where it made sense to upgrade our equipment and in other areas offered that we didn’t need to spend the money on upgrades over what we already had.

Not only that, post installation, Debbie has been attentive and helpful; checking in to ensure everything was working properly and, when we had a small hiccup with our system after initial activation, was incredibly responsive, ensuring our issue was resolved and everything was in working order.

In addition, after a month in the house, we have had a couple instances where we did not turn off our alarm in a timely fashion when entering the home. Marshall’s Central Station called immediately to check that everything was OK. At the end of the day, that’s what you’re looking for in an alarm company!

In short, Marshall is top notch. I couldn’t recommend them more highly. And I still get lots of satisfaction from turning on/off the alarm from the app on my phone and not having an extra service charge every month to do so.

Marshall is marvelous.
In our 1st house, we used a company that maximized their profits and minimized customer service. Our 2nd and current house came with a CT-based outfit which whined that we were too far from CT to warrant a field visit.
Then a neighbor recommended Marshall.
I like everything about Marshall. Marshall is honest. Marshall does not overcharge. Marshall puts their customers first. New-account rep/installer is smart, quick and efficient. 100% of employees I’ve encountered, office and field, focus on their work which they complete with competence and grace.
I recommend Marshall Alarm Systems, Inc., a bright star.

Marshall alarms did an amazing job at setting up a system in my new home. Debbie was fantastic and has continued to be as the installation occurred. I would recommend her with 100 stars. My system works great and includes temperature monitoring and water level monitoring for the washer. Easy to use. Makes me feel very safe and secure.

Positive: Professionalism, Quality, Responsiveness, Value

From the initial sales call to the installation and billing, Marshall Alarm gave me an outstanding experience. Debbie in sales was awesome and explained all the various updated technology available in an alarm system. Rob our installer was equally as awesome. He was neat, professional and also explained how the system works after being installed. I highly recommend Marshall Alarm.

Debbie was wonderful to work with. She has a great personality and is very knowledgeable about the alarm system. She walked through the house with me, letting me know what should recommended to be alarmed and why. When Marshall came to install the alarm, he was very professional and answered all my questions. He stayed to practice once the alarm was set up and made sure I was comfortable using it. They both reassured me numerous times that I can call anytime with any questions or concerns. Very nice company to work with.

First of all, Debbie is incredible to work with. Tremendous experience, lovely personality, understands home security in a way that few people do in the entire country. She has been in this business for over thirty years. Remarkable. Then the actual installation team with Marshall Jr at the helm. They were able to get the install done rapidly in a house that presents considerable challenges. Beautiful aesthetic work and done with incredible efficiency. I cannot rate them highly enough. I strongly recommend for anyone who is looking for even a simple home security project. And they can clearly handle major extensive projects as well. Look no further!

Utilized Marshall Alarm to install an updated security system and security cameras at a large residence. The service started with a security consultation where a member of Marshall Alarm’s team comes to the residence to understand your security concerns followed by a walk of the property to point out potential issues and mitigations. From there they build and price out several options and then set you up for installation. From start to finish their team is very professional, attentive to detail and makes sure the customer understands and can work the system before leaving. Furthermore, the central monitoring service they use is very responsive. Having moved and switched security companies to Marshall Alarm, I was shocked to see how quick their central service is to respond to alarms, even non life threatening alarms like low temp. Highly recommend them for all your security needs.

We switched alarm companies and are delighted with the seamless transition. Very attentive staff…

“Thank you so much, Marshall. David said you are TERRIFIC and it was so great you were there when the fire inspector was there!  For ever after, we will direct all our new tenants to using your company. We are very grateful, and grateful to Tim and Mickey for recommending you!  Thank you again for being available on such short notice.  You were great!!!”

“After purchasing a property with a Marshall system already installed, I called Debbie to setup an orientation visit. She quickly assessed that the system was very outdated and in need of a technology refresh. She was keen on ensuring we weren’t “oversold” on items we didn’t need and was patient in explaining all of our options. Installation day came quick and the experts – Marshall Jr and Rob – went above and beyond to make sure we were completely satisfied with the new system and made sure all aspects of the components (even those they didn’t install) were operational before leaving. The very next morning we received an unprecedented wake-up call from Central Station due to a false alarm tripped by our dog. Rob was right back to our home that morning to remedy the situation. I am extremely pleased with the level of service provided by Debbie, Marshall Jr, Rob, and the entire Marshall Alarm team. It was very important for me and my family to feel safe, secure, and stay local. Marshall Alarm deserves all 5 stars – and then some.”

“We had a great experience working with Debbie and Marshall security company. We were fooled by one company and we were hopeful to find a company that was reliable and trustworthy. Debbie was able to fit us into her schedule, *very last minute. She was punctual when she came to assess the home and our needs. Took Covid precautions seriously. Most of all, she was friendly and knowledgeable of any questions we had. With a growing family, safety is our biggest priority and we haven’t thought twice while working with Debbie at Marshall Security. She has always made herself available, even after hours.”
– Angelina Dushaj

“We contacted Marshall Alarm when we needed to update our 10 year + alarm system. We had contacted some of the bigger commercial companies and found them really expensive and impersonal. Debbie responded promptly and discussed our needs and wants. She did not try to “oversell” us; she simply explained the options and let us make our own decision. She was attentive and detailed answering all of our questions. The overall cost of the update and the monthly monitoring were very reasonable. MJ did the installation; he was very respectful of our home and did an outstanding job of installing the new equipment and showing us how to operate it. He made sure everything was working perfectly and didn’t leave until we were completely satisfied. We had a wonderful experience with Debbie, Mj and the rest of the team. It was like working with family rather than some anonymous big company. 5 stars! Recommend highly!”
– Janet Hughes

“My primary concern was converting my system from an old nationwide provider. The team at Marshall provided the most input, concise planning, and all things considered was a good price point as well. The installation went smooth and the introduction to the system as well. As someone accustomed to using alarm systems everything else was a breeze, but the icing on the cake was knowing I have direct contact with a local representative, but hopefully I will never need that. Good to know though!”

“Most responsive security company I have come across! I should have made the switch to Marshal Alarm sooner and saved myself the aggravation of dealing with multiple no-shows from a previous unnamed national company we used. We were lucky to have Marshall jr. upgrade our system and fix all the issues that we had. He was very careful and followed all the safety recommendations when entering our house (mask on all the time, protective booties, etc). Totally knowledgeable and comfortable explaining what he needed to do. A couple days later when we had an issue with a device, Marshall came over to fix it within hours, not days or weeks – even though their schedule that day was fully booked. We were treated like family no matter whether it was Debbie answering the phone or another employee. Their price for their services and monitoring is very competitive, too. So glad I found them.”

“We needed an alarm system installed and had no idea which alarm company to use. Reading the excellent reviews of Marshall Alarms we decided to call and set up a home consult visit. Debbie came to our home and told us exactly what we needed. She was totally honest, told us what WE needed for OUR house to be secure. We gave her a deposit and set up date for installation that very same day. Debbie was professional, caring, honest and trustworthy. What else would we be looking for! Marshall and Rob installed our system. They were on time, neat and extremely patient when explaining how to use the system and the phone app too! It has been 3 weeks now since the installation. All is working perfectly and soooooo easy! We are telling everyone at work and our friends about Marshall Alarms. They are the very best!!!”

She did a great job of mapping out where the cameras would be on our property and assured me that she and her installers would be there 24/7 if any problems arose. Installer Marshall and his team were excellent! Marshall was patient and very receptive to all our concerns as to how and where the cameras would be placed. The job was done neat and clean and the cameras are super clear. Very nice, honest guys – they made us feel very comfortable that we made the right decision in going with Marshall.”

They are responsive, always follow up and explain everything to their customers. Our installation by Marshall Jr. was seamless. He was on time, courteous, and taught us everything we needed to know about our system. Don’t choose another alarm company!”
– J. Lichtenstein of Pound Ridge, NY

May 18, 2018
“We contacted Marshall Alarm when we needed to update our 10 year + alarm system. We had contacted some of the bigger commercial companies and found them really expensive and impersonal. Debbie responded promptly and discussed our needs and wants. She did not try to “oversell” us; she simply explained the options and let us make our own decision. She was attentive and detailed answering all of our questions. The overall cost of the update and the monthly monitoring were very reasonable. MJ did the installation; he was very respectful of our home and did an outstanding job of installing the new equipment and showing us how to operate it. He made sure everything was working perfectly and didn’t leave until we were completely satisfied. We had a wonderful experience with Debbie, Mj and the rest of the team. It was like working with family rather than some anonymous big company. 5 stars! Recommend highly!”

“Marshall Alarm was referred to me by a friend. After contacting them, their representative Debbie came by to assess my needs for a security system. She was very professional and knew exactly what I needed to feel secure in my home. She was personable and did not oversell. The day of install, Marshall Jr. came by to install. He was neat and did the job very professionally. He took his time explaining the use of the keypad to me-also offered me his cell phone in case I had any problems. I couldn’t have asked for more! Very happy! Would highly recommend!!”
– J. Gilligan of Croton on Hudson, NY

” I just had to share my experience with a maintenance issue I had with my alarm system. I called on Monday and the woman who took my info could not have been more accommodating (I wish I remembered her name). In any event she had Robert here first thing this morning. I cannot tell you how satisfied I am with his professionalism and service. Unfortunately in today’s world it seems as though customers are forgotten about once the sale is made. Marshall Alarm is the exception to that. Robert took his time addressing the minor issues we had but also took the time to troubleshoot the entire system. Like I said, that is customer service. Many businesses could learn a lesson from your company and employees. Many thanks from a lifelong customer. My hats off to you and your entire team.”

“These folks provide excellent and reasonably priced service, during installation and particularly afterwards. They have provided great, personable follow-up service. We had purchased a house with a good functioning alarm system that Marshall took over and improved upon, instead of selling us a bunch of costly new equipment as a lot of other companies that we talked to tried to do. I really appreciated the time Marshall spent with us to develop a reasonable solution to our particular needs.”

“Moving from the city into Yorktown Heights seemed safe enough, but Marshall’s alarm system has made this transition even better. We have been in Yorktown for 4 years now. Any time the alarm goes off, false alarm of course, we get that check-up call- I actually just stay by the phone and wait for it. Dating back to the installation process, it was quick and easy. The technician was polite, friendly and thorough. I would recommend the system services to everyone in the area. The prices are perfect and the services also.”
– M. Graciano of Yorktown Heights, NY

October 3, 2017
“I’ve been a customer of Marshall Alarm for many years – at my previous address and now at my new home (for the last 16 years). Marshall is always immediately responsive whenever I have a problem (fortunately they’ve all been minor). My last service call (check the system, change all the batteries, etc) was performed efficiently and quickly the day after I called. The service man came at exactly the promised time. I feel so comfortable being able to rely on this very responsible company!”
– E. Kingsley of Briarcliff Manor, NY

October 1, 2017
“Just started with this company after putting up with my former company for 21 years and running into numerous service issues. This is a family owned company and seems extremely professional and competent. From the first meeting with the rep, Deb, I had the feeling that it would be wise to switch to Marshall. They took over my system, added features that were lacking and all seems to be running seamless and well! In fact, the owner himself came to do the take-over work and showed a high degree of competence and caring!”

And the installation was top notch! On time, courteous and professional. Don’t look anywhere else. Hire these guys!”

Outstanding….thank you Debbie, MJ, Bob and Dianna for taking care of us!”
– J. Obst of Westport, CT

July 12, 2017

– E. Amsel of Chappaqua, NY

July 3, 2017
“My home was serviced by a different local provider and after being very unhappy I emailed Marshall Alarms– within 12 hours, I received a phone call, email, and appointment for an in-home visit by Debbie. Debbie is WONDERFUL– she provided us with all of the information we needed to make the right decision and SWITCH TO MARSHALL. She was able to show us how pieces of our alarm that we were told wasn’t working actually was and made some super helpful recommendations on areas to improve. Debbie is a true professional and certainly knows what she’s talking about– she goes above and beyond to make sure you’re an informed, happy customer. MJ came out to check the system, install some new components and again, was a true professional in every sense of the word. He was kind and patient when answering questions and never rushed. Not only am I ecstatic that I switched to Marshall Alarms I feel safer knowing that I did!”
– B. Levenson of Bedford, NY

April 18, 2017
“We had a great experience from start to finish with Marshall. The initial meeting was extremely thorough– Debbie is so knowledgeable, and gave us a fair and realistic understanding of the areas where our home was vulnerable and suggested a reasonably priced plan to address them. The team who completed the installation was also fantastic– they were lightning-fast but spent plenty of time explaining the new system and ensuring that we were fully comfortable using it before they left. Highly recommend!”

November 7, 2016
“I had ADT for many years and their cost of service went up as the services included and responsiveness went down. I had enough so I talked to several local companies and Marshall responded quickly to my inquiry and answered my technical questions (I am a tech and know quite a lot about alarm systems) and they answered correctly. They knew the system I had and did not try to upsell me to a new system – I know this system can be taken over with a chip change and other vendors were telling me that I am wrong – so I gave Marshall the job and they gave me a great price and a fully professional vendor to customer experience. The did exactly what I knew could be done. Nice people. Excellent!”

She also followed up several times to make sure everything was running smoothly. The technician, MJ, was prompt, knowledgeable and very patient and courteous while explaining to three technically challenged adults. We liked the idea that it is a family owned business that does not contract out any of their work. We would definitely use them again and recommend them to others.”
– B. Cray of Irvington, NY

August 7, 2016
“Everything went smoothly and quickly. Debbie the salesperson was extremely knowledgeable, thorough, and tried to save money where prudent. The installation was equally as smooth. Everything was installed, neatly and with the utmost of professionalism. They made sure I knew all the features of the system and were patient in teaching how to use it. There have also been follow up calls to make sure everything is ok. Very happy with the experience.”
– K. Birnbaum of White Plains, NY

June 25, 2016
“Marshall Alarm is a great, family-owned, local alarm system company. I did not want to use a big, national chain with strangers in and out of house and with access to my system. So, I used Angie’s List to find Marshall Alarm and installed my alarm system about two years ago. The initial installation was done by Marshall Jr., the founder’s son. It has been a great experience and decision. For any issues or needs we’ve had, we called and Marshall Jr. is right there taking care of it again. They are professional, honest and reliable. Highly recommend.”

– C. Sheer of Mahopac, NY

January 12, 2016
“After researching the security companies that service Westchester County, we knew that we did not want to go with one of the big security companies like ADT or Slomin’s Shield. We wanted more personalized service and straight forward pricing. Marshall’s was one of two security companies that we interviewed. Both security companies had friendly, professional and extremely capable professionals. Right off the bat, Debbie was very straightforward with me. She told me that they would beat the price of any one else we met. And she was right! Although security equipment is expensive, Marshall’s monthly monitoring service is very reasonably priced. We also saved money by reusing sensors and motion detectors from the prior security system (Marshalls just switched out the batteries so everything was fresh). Installation by Marshall Jr. was also very quick and efficient. Both he and Debbie were extremely knowledgeable. We’ve had the security system for a little over a month now, and we’ve had no issues whatsoever!”
– T. Chieu of White Plains, NY

January 6, 2016
“We had a situation where the smoke/fire alarm was activated; the system worked perfectly and the response, professionalism and assistance by Marshall couldn’t have been better! We are very grateful and very satisfied with your services. A near catastrophe was avoided! Thank you very much! I heartily recommended your services!”
– E. Preusser of Garrison, NY

January 4, 2016
“This is our first house and, to be completely honest, I had a hard time sleeping without an alarm system for the first few days. After reading the reviews of several other alarm companies, I selected and contacted Marshall Alarm. I appreciated the fact that their reviews were consistently great for the same reasons: courtesy and professionalism. Debbie, their salesperson, could not have been any nicer and more professional. As soon as I called her to set up an appointment, her calm demeanor began to ease my fears and she was at our house two days later to do a walk through and to give us a quote. Per my request, she even went above and beyond by moving the installation date to an earlier day than originally planned. However, Debbie isn’t the only amazing person working at Marshall. Marshall Jr., the gentleman who installed the system, was extremely courteous, prompt, knowledgeable, meticulous, thoughtful, and amiable. If you’re looking for an alarm company whose employees and services do more than live up to their great customer reviews, I highly recommend Marshall Alarms. You will be extremely happy and satisfied, from the moment you speak with Debbie to the moment your alarm system is up and running.”

– M. Hermann of Chappaqua, NY

April 6,2015
“The service we received from Marshall was great from start to finish. We looked at Marshall and one other regional company when deciding to purchase an alarm system. We decided to go with Marshall because they offered more coverage of the house for less money (sensors & motion detectors) and understood the technology more than the other company with whom we spoke. They were very helpful and knowledgeable during the sales process; he gave me a quote over the phone that was spot on. I had forgot to include a window in the totals I gave him and he didn’t charge me extra when they came onsite to finalize the order. Marshall Jr. and another tech performed the installation. They were on-time, professional, and did a great job installing the hardware. Before they left they explained how to use the system, accompanying iphone app, and log into the website to change settings. Overall a top notch firm and great experience. Highly recommend!”

The installation by Marshall was done on time, appreciated thorough explanation of how to use the system once installed. We feel very confident and have peace of mind now that the system ins installed and working!”
– M. Dollar of Bedford, NY

November 25, 2015
“Marshal Alarm Systems installed an alarm system in our house. We were very happy with the service we received from Marshall Alarm Systems. There had been some robberies in our neighborhood and we were concerned and wanted some security and piece of mind. The sales rep came and surveyed our house and never tried to use our fear into getting us to buy more than we needed. She told us that she was able to use the old, outdated system that was already in the house when we bought it so there was minimal work that had to be done to the house. She did not pressure us and we called her the next evening and set up a date for the installation soon after our initial meeting. Marshall Jr. arrived at our house at the time he said he would and finished the job pretty quickly. In addition to the alarm system, he swapped out our old smoke sectors for new one and explained how to maintain them. He was very patient in showing me how the app works and how the system worked. He waited for my husband to come home and went through the whole process with him as well. The system is very easy to use and works well. Marshall had called after the installation to see how everything went. We were happy with our experience with Marshall Alarm Systems and highly recommend them!”

“My wife hired ADT to install whole house alarm system, they were very nice but the system did not meet our needs. Marshall removed the ADT system and installed their system. Very responsive local nice people to deal with, we feel safe, thank you. Install completed on time and explained everything.  We felt they were much better than ADT system. The installed smoke and heat sensors in fire prone areas…Kitchen, Living Room with fireplace and garage, ADT said not necessary. Marshall Alarm Systems were a pleasure to deal with! Thank you Angies List we found them from your list. Would recommend as a top notch company!”
