Good company, good customer service, very professional service personel
This is a great local company to work with. They have been around a long time and they really know their stuff!
They are very professional and Warren is an excellent technician.
keeping me safe both at home and work for years now. excellent staff in every department. thanks !!
What a joke of a company can’t even answer their own front door…. I wouldn’t work with them.
Great local security firm with highly personalized service tailored to your individual needs. Excellent customer service department.
Great service, even on older hard-wire systems. Easy to schedule appointments and prompt, professional service. Strongly recommend!
I called here to see if they could help me make changes to an existing fire alarm panel. Ashley told me that they do not do that for anyone but she was willing to have me sign a monitoring agreement.
We’ve been using Supreme Security for over 20 years. Their prices are reasonable and their service is great.
great company – what is important for me is the fact that the few times that there have been questions or issues over the years, no matter when I call, a company rep (live person) answers and they are always extremely friendly and patient
The phone number is not in service, please advise what the correct phone number is.
I am the owner at 20 Mechanic street. Please be extra careful with these guys.They will make you sign a 5 year contract and even if you sell the place they will want you to pay for it. I am the new owner and they tried to sneak in a $99 …
I found their sales practices and initial contract to be deceptive. Having a one year lease on a condo I engaged supreme security for monitoring. I moved this past December, called Supreme and cancelled my service after 4 years. A month …
We had a few small issues along the way but the end result seems to be great. We were all really happy with the service Derek gave us. Supreme Security Systems seems to be a good security company. I would recommend them to anyone needing security work. I’m sure we will be calling you again in the future.
supreme security responded quickly to my request for preventative maintenance. technician answered all my questions and provided a listing of each unit, its location and purpose.. Supreme has been great for several years and we continue with a service we know and trust.
I got their services because the house I bought previously had their equipment installed. Biggest mistake ever, most unprofessional company I ever dealt with. No one knows what’s going on, customer service is atrocious. If your equipment …
We have used the service of Supreme Security for many years. When we sold our home last year we contracted with them for service in our new home. They are Great! The agent who coordinated the transfer and install was professional and …
Great in the beginning with pricing, etc. but, I advise you, DO NOT PAY IN-FULL. Wait until they finish the job, because they showed up to install with the incorrect hardware a few weeks ago and I have not heard from any of the install team …
Rating them a 1 for now. The sales person was nice and receptive up until we had issues (that are still unresolved). He has not acknowledged or answered my last message asking for help on who to contact because the camera system is not …
This used to be a wonderful company.
I have been with them since at least as far back as 2012.
They were acquired by “Securitas” and, since the acquisition, they have lost all …
