"Used MAS to upgrade the security system in our new home. Debbie was terrific and went through the entire house to highlight what was needed and MJ was top notch on the installation. The entire MAS team is incredibly responsive on all issues and it is very comforting to me as a homeowner. Feel great having the new system, which is super easy to use. MAS is not cheap for sure ... but they are worth it for the peace of mind. Highly recommended!"

"Excellent cameras and wonderful team of installers, sales and office support! Debbie, the sales rep. was wonderful to work with. 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."

"Great experience with them from start to finish! The sales person, Debbie, was knowledgeable and made good suggestions specific to our home. The installer was THE BEST! I wish every contractor that cane into my home was like him. He was punctual, courteous, neat, very personable and explained everything. Price was competitive and install package price was the best of the 3 quotes we received. Honest people and fair! Highly recommend, just installed today but I felt so compelled to write a review!"

"We have had a great experience right from the start with Marshall. They are knowledgeable, experienced, upfront, and have great customer service. Debbie came quickly and gave us an honest assessment of what we needed without trying to up-sell at all. Installation was just as good, they took their time and made sure we understood every feature before they left. And since then we have been very happy with the system, the ease of use, and the peace of mind. Highly Recommend!"

"Great customer service from start to finish. The whole staff, especially Debbie was extremely helpful and knowledgeable and easy to work with. 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!"
- J. Hughes of Briarcliff Manor, NY

"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

April 17, 2018

November 29, 2017
" 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."
- T. McAliney of Brewster, NY

MJ went above and beyond to use my existing wiring during the installation which I appreciated so much! I've been a customer for two years now and have had absolutely no issues. I have recommended Marshall Alarm to friends who are also happy customers now. They're wonderful!"
- R. Gussin of Harrison, NY

- H. Albano of Yorktown, NY

October 8, 2017
"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."
- H. Amano of Ossining, NY

- M. Herrick of Carmel, NY

"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!"
- T. Neustein of Chappaqua, NY

- J. Wong, Asian Temptation of Poughkeepsie, NY

September 23, 2017
"Most companies over promised and under deliver. Not Marshall! From our first contact until the work was completed everyone was extremely professional, honest, and thorough. Other security companies tries to sell us a full system replacement. Deborah at Marshall's came in and recommended some inexpensive upgrades that really did the job. And the installation was top notch! On time, courteous and professional. Don't look anywhere else. Hire these guys!"
- W. Winters of White Plains, NY

Both Robert and Marshall were very efficient and courteous during the installation and easily answered any questions we had. We are confident that our relationship with Marshall will be a positive one going forward."

August 8, 2017
"We upgraded our home security system this past month. We cannot say enough positive things about our experience from our first contact to set up the consultation to determine what was needed through the installation and now the monitoring and protection. Marshall Alarm is the best, bar none, security alarm company providing top quality monitoring, alarm systems including video surveillance. Outstanding....thank you Debbie, MJ, Bob and Dianna for taking care of us!"
- J. Obst of Westport, CT

August 7, 2017
"I feel incredibly satisfied and more importantly safe, after Marshall installed my alarm system. Having just moved into Westchester with my family, I searched for a trusted and proven Alarm system provider. Marshall came highly recommended and they did not disappoint. Debbie appraised what was needed and Anthony followed up with the install. Both did a standout job. Thank you Marshall!"
- M. Tarpinian of Chappaqua, NY

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!"
- H. Kapner of Chappaqua, NY

March 13, 2017

- W. Manzo of Cortlandt Manor, NY

November 30, 2016
"Installation was done in a timely and professional manner. Job well done!"
- J. Ordonez of Bronx, NY

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!"
- J. Klett of Carmel, NY

September 23, 2016
"Great job! Thank you for your courteous, professional staff."
- C. Di Dio of Goshen, NY

September 15, 2016
"It went very well. The sales assistant was very professional and responded to our call quickly and within days she came and evaluated what we needed to get our system up and running. 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."
- W. Quarless of Croton-on-Hudson, NY

April 14, 2016

"Debbie(sales expert) was so amazing from the first call I received from her to present. She took the time to explain to me the system and devices that I needed to make my family and home safe. She gave me such great tips and worked with me to ensure that I felt secure. She makes herself accessible when needed. MJ installed the system and was so friendly and fast with installation. He knew what needed to be done and cleaned up any mess that he made and effectively taught me how to work the keypad."
- A. Santos of Mahopac, NY

February 28, 2016
"On short notice they installed a full alarm system with offsite video monitoring for my property. Marshalll delivered exactly as promised. Flawless service."
- C. Guzman of Norwood, NJ

February 4, 2016
"The service was excellent from the very first phone call to request information. The in house visit to determine what we needed was performed by Debbie and was exceptional--she clearly knows her stuff and was a pleasure to interact with. The description of what would be installed matched exactly what was installed down to the way it would look on our doors where the sensors were placed."
- T. Barefield of Katonah, NY

January 31, 2016
"Technician Anthony, (second service call here) was so professional, friendly and knowledgeable. Explained system(s) glitch, etc. Pleasure to have on job!"

"It is so rare in these times to come across someone as competent and pleasant to do business with as Debbie. Upon entering my home for the first time, she quickly assessed what was working and not working, and clearly presented my options. Her honesty, confidence in your workman and company is over the top terrific - you could not ask for better representation. Thank you!"
- 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."
- J. Leiva of Brewster, NY

December 11, 2015
"Marshall Alarm is the only company you should ever hire!! I did my due diligence and met with four different alarm companies to discuss what we needed to ensure the security of our home and make sure we used a company that knew what they were doing. Marshall Alarm was the first company I met with and Debbie set the bar very high. From the moment I met Debbie, I knew she was not only an expert on security but she was passionate about it without instilling fear. Debbie did an amazing job of explaining why she was making certain recommendations versus others, she explained how the different components worked and asked very detailed questions about what my plans were for each room to make sure what she was recommending was the best option. Debbie thoroughly answered all my questions, and as a first time home owner, I had a lot! But above all that, Debbie is just someone you intrinsically trust because she is genuinely a nice, good and honest person. She's not just a salesman who is trained to just sell. Debbie's been in the industry for over 20 years and it shows. I met with three other companies after meeting with Debbie and it was an absolute no brainer for me. As it turns out, Debbie isn't the only amazing person at Marshall Alarm. Marshall Jr. came to install the system and he too was the ultimate professional. He's unbelievably knowledgeable, courteous, meticulous, thoughtful and proactive. He takes pride in what he does and it shows in the level of detail and care he employs. I can't say enough wonderful things about this company. I know sometimes it seems safer to go with a large or national company, but trust me, going with a smaller, reputable company who has been in business as long as Marshall Alarm has been is worth the few hundred dollars more you may pay. And there are absolutely no hidden fees unlike with some other companies! The old adage "you get what you pay for" definitely rings true here. Security and safety is not something to cut corners on. You want to make sure you work with a company that installs the right components for your needs, installs those component properly, tests them time and time again, explains how everything works, and has a central service that is reliable no matter what time of day or night. I could go on forever about Marshall Alarm."

"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!"

Debbie is an outstanding salesperson with decades of home security system experience. She was extremely thorough, prompt, passionate, knowledgeable and provided a level of customer service and support that we rarely see anymore. Marshall Jr, one of the owners, personally installed the system with one of his colleagues. Marshall is a perfectionist and he immediately gives you a feeling of competence and subject matter expertise.

"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!"

"After getting estimates from other companies and meeting with their representatives my husband and I were blown away with the level of knowledge and professionalism we found at Marshall's. We weren't looking for the cheapest alarm system solution we were looking for the best value, and we certainly got an incredible security solution! Marshall's worked with us to meet our exact needs, with 2 kids and a dog in our near future we wanted something that was both dynamic (had, away, home, and "vacation") modes, that could be controlled from our iPhones. We decided on a system that included glass break detectors, motion detectors, door alarms, etc. and we couldn't be more pleased with the system. Debbie really helped us explore all of our options and really knows her stuff. I would highly recommend Marshall's Alarms for anyone who is looking for professional, personable, and reliable security systems."

"I purchased a new home in May 2013. I contacted several alarm companies about reactivating the alarm system which was already there. Each company indicated that because they hadn't installed the previous system themselves, they couldn't reactivate it without installing a new circuit board in the control panel. Some companies further indicated that as a result of installing a new board, they couldn't guarantee the existing keypads would work, so I'd need new pads as well (I have four keypads, so at a couple of hundred per pad, it adds up). Between these issues and the up-selling, I received estimates of between $500 and $2000 to reactivate. Then I called Marshall and scheduled an appointment for Debbie to inspect the system. She arrived promptly and after a review, assured me they'd be able to reactivate the system, thereby saving me a new circuit board and keypads. I was dubious given the previous estimates, but she called her associate MJ and confirmed they could. MJ arrived to reactivate the system and I waited patiently for the moment to come where he would explain why they couldn't reactivate the system after all. That moment never came and MJ had the system up and running in no time. Neither Debbie nor MJ ever gave me a hard sell on additional equipment, but MJ did recommend a few small things (a water leak detector near my hot water heater in the basement and a smoke detector in a hallway which didn't have one. It'd be hard to argue these were bad ideas or unnecessary). The foregoing coupled with a reasonable price for monthly monitoring makes me a fan of Marshall Alarm."
