"We wanted to get on board with the current trend in doorbell cameras. Got a quote from ADT Provider, known as Safe Street USA, and felt their offer was more than fair. We have door sensors and motion detectors inside and the doorbell camera mounted outside. Nice to feel “with the times” in home automation and security."

"We didn’t realize how many items could be integrated into our ADT security system. But after speaking with the helpful representative on the phone for about 10 minutes, we decided to go forward with their full home automation package. Not only are the doors and windows secure, but we can control lights, the thermostat, and the garage door."

"in 2010 I had windows installed along with a front entrance door with a sidebar. Withgin 2 years the paint chipped on the outside and they had to replace the whole thing. Now, just 4 years later, the paint is chipping again, and in addition to that, the window above the front entrance door is now fading due to broken seal.Not what I expected ....."

"Tony did a great job mounting my television. Tony and his assistant made sure everything was secure and lined up properly. Everything was neat and clean. I would definitely recommend Tony to all my friends and family."

"Called John about a new door and storm door installation. The response was quick and the technician did a great job. Very clean and fast job."

"Had a new bifold door installed. From quote to installation, less than a week. Tech did a great job. Asked them to quote another job!!"

"Iâ m very pleased with the entire process from initial sale through the installation of the windows and doors. The quality of the windows and doors plus the workmanship of the installers is very good. I certainly recommend this company."

"Excel windows was fantastic. I actually had them install new siding for the home and replace the front door and 2 sliding doors. Competitive pricing with stellar customer service from Sales, Office Personnel to Siding and Door installations. Can't recommend them enough. Arrived on time and very responsive to phone calls. My home looks amazing!"

"I had rainwater coming in through a door and window frame. Dario and Juan knew right away that the problem was coming from where my deck meets the siding. They removed deck boards to discover a gap in the siding. Checked for water damage (thankfully no damage). Sealed the gap. I have not had any rainwater issues since. Price was totally reasonable. We discussed other future repairs/projects for my home and I look forward to working with them again."
