"Ultra Guard Security Systems did an excellent job. They were very professional, knowledgeable and technically competent. Lindsey Pearce was very easy to work with. She analyzed our home environment and provided an excellent proposal. UGSS was able to incorporate a manual bypass system that was part of our original security system. We requested proposals from four vendors, including the incumbent and only UGSS responded. Finally their call center is very prompt. I highly recommend Ultra Guard Security Systems."

"It has been years since we had a home security vendor and professional monitoring. Finally got around to re-adding security to our list of home services. It was more than time. Tried a package from amazon but had issues from the start. Ended up returning it. ADT ended up saving the day. We didn’t want to waste any more time with cheap security products. ADT had been the perfect fit for what we were looking for and needing."

"I have them installed security cameras in my house. The workers were professional and knowledgeable. The equipments of their choice are also good. I paid more than I originally expected, but overall speaking the experience is good and I am comfortable."

"Bill, the owner, and Brandon, the technician, both provided world-class customer service from start to finish. To begin, Bill stopped by to perform the in-home consultation and provided recommendations on how he could bring my vision to life with indoor/outdoor security cameras. Brandon did an outstanding job with the installation of all of my Google Nest cameras, assisting with camera placement for the best viewing angle, seamlessly fishing the power cables through the walls, and adding a classy touch by installing brush pass-through wall plates. Brandon managed smaller details such as the cable management for the outdoor camera above my garage flawlessly as it was presented in a clean and neat manner. Both Bill and Brandon treated my home as if it were their own and I will definitely seek to work with them again in the future. Candidly, I had another in-home consultation conducted by one of the big box retailers to help with this project prior to looking to Home Advisor, but I was so disappointed with that experience that I'm glad that I was paired up with NexImage Inc. If you are looking for service professionals that will get it right the first time, look no further than NexImage Inc. Thank you again Bill and Brandon!"
