Best security door installation pros near Cabin John, MD

"I was having trouble with one of the zones in my house with our alarm we purchased with ADT Premier Provider. Ryan came out and checked the system and the battery in the control box; and those were all good. He determined that the sensor on the slider door was the problem. He cleaned the track, reinstalled the sensor on the door and secured it. The last thing he did that put his service OVER THE TOP was that he knocked down a large wasp nest that was in an area I couldn't reach even with a ladder. This was the best customer service we’ve seen in a long time!!"

"Protect Your Home group with ADT has exceeding our expectations in getting a new home security system. In the end, everything was a breeze and not stressful whatsoever. We tested the siren and our neighbors 2 doors down could hear it; which is what we were hoping for!"

"I had a full view glass storm door with sidelites installed in front of my Provia entry front door. The door is very sturdy such as thick heavy metal, lexan glass is clear, the hinges are smooth and strong, the lock is secure, the powder coated paint is beauty. the weather striping is robust and tightly sealed. The manufacturing process took a little longer than expected. A minor adjusted was needed for the lock. Medallion sent someone out immediately to solve the problem. My Provia Front entry door is awesome. I really wanted a full view security storm door to allow the Provia door to be on full display. In addition, to providing full security. Medallion knock it out of the park."
