"We had an exceptional experience with Schadel and Nick at Novalarm Systems. Schadel worked with us throughout the entire process from helping us build a system that best suit our needs, to follow up after the install. Nick performed the majority of the install. He was worked around us to help avoid downtime in our shop and left us with a very clean and well laid out system. From start to finish the guys at Novalarm were extremely professional and provided us with a very high quality product. I would highly recommend them for all of your security needs."

"My telephone system stopped. Novalarm Systems came to the rescue. Shadel proved to be very competent in identifying the root cause: the Ethernet port had been affected by a lightning strike. He was able to reset the configuration quickly and give us back a working telephone system. Coupled with his technical skills, Shadel is tuned in the customer stressful situation. It was a great experience working with him."

"We had a fantastic experience working with Novalarm for our security camera installation at Jack’s Mill. The team was professional, knowledgeable, and easy to work with from start to finish. Schadel was especially helpful throughout the process—he guided us through the system setup and has been consistently responsive whenever we’ve had questions. The team helped us identify the most effective camera placements to monitor the property, and the installation was seamless. Highly recommend Novalarm to anyone looking to enhance their property’s security!"

Their team was professional, efficient, and highly knowledgeable throughout the entire process. They represented our company exceptionally well, delivering top-tier service and expertise that exceeded our client's expectations. Communication was smooth, the installation was completed on time, and the quality of work was outstanding.

"I wanted to take a moment to express my appreciation for the recent CCTV conversion project in Chelmsford, MA. In my 8 years as a MAPM, it was by far the smoothest project I’ve ever experienced. At no point in the process did I have to escalate a concern or even worry about an issue for longer than an hour. John from Novalarm was an unbelievable support to the store with an incredibly fast response time throughout the entire remodel project. I’d personally request John for ALL projects in my Market if that was an option. Thanks again for totally escalating the catch remodel standard with Novalarm."

"Novalarm has been absolutely wonderful to work with! Their team is extremely professional, efficient, and reliable. They were quick, on time, and their communication throughout the process was excellent. They recently assisted us with our fire alarm system at FJ Luxury Flowers, and everything was handled smoothly and with great care. I highly recommend Novalarm to anyone looking for outstanding service and trustworthy support."

"We needed to replace the cameras at our tennis club and began by reaching out to several companies for estimates. Novalarm Systems stood out right away. Schadel, the Director of Sales & Marketing, came to the club, asked all the right questions, and provided knowledgeable advice along with several solid options. Within just a few days, we received a detailed estimate that clearly outlined the work as discussed. Although we received quotes from other companies, it quickly became clear that Novalarm was the right choice. On installation day, Schadel arrived with Ben and another team member. He stayed to ensure everything went smoothly and according to plan. The following day, Jonathan, the owner, personally came by. He’s hands-on, highly technical, and detail-oriented. The entire crew was professional, friendly, and committed to doing the job right. I would recommend Novalarm Systems without hesitation—they truly set the gold standard. It’s a pleasure working with a company like this."

"John came out within an hour of me calling him because he knew my situation was dire with my children doing remote learning. They were here for over an hour trying to figure out why the internet was not extending to our attic with the extenders we had in place. John helped me find the proper extender online that I needed and told me to call them back if I had any issues. Unfortunately after installing the new product we were still having issues in our attic. I called John back and he came out within 2 hours of calling him. It was determined that a hardwire connection needed to be installed in the attic. They spent roughly 4 hours running the wire from our router on the first floor, into our basement, out the side of the house, and up to our 3rd floor (install was so discreet you canâ t even tell itâ s there). They cleaned up after themselves, were very informative and dedicated to making sure the problem was solved before leaving. They were also very friendly and easy to talk to, and that by far is the most important thing to me when doing business with someone-especially when theyâ re in your home. I would recommend John and his team to anyone, and intend on calling them for our future projects."

"Jon's communication right from the onset was great. He showed up early for the appointment and did a great job. He answered all my questions and put me at ease with my new installation."
