"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."

Customers say: True professional

"SECURITY WINDOWS AND DOORS: I have spent a LOT of money putting in security windows and door as my home has been broken into many times while Charlie was here. I have had 2 companies, a local was fantastic but expensive yet worth it. They can no longer find someone to make security windows After contacting others who stopped calling (Medallion) when the 3 window job looked not worth the effort, I found Michael Byers on HOMEADVISOR/Angie's List. It is in Gaithersburg; he came right away to measure my windows; he special made one window for the cats so they can get their fat butts through. Windows are usually about $650 each but he charged $1000 for 3 windows and installation -- and they are the fancy windows. I was shocked and they were installed within a week. He has a factory where he makes the doors and windows himself. My HD door lacks were awful. On 3 doors, he installed new deadbolt and handle locks for a little over $200 -- including installation. The doors lock wonderfully and I have the same key for all of the locks. His number is 301-252-5117. With so many break-ins in my area, security windows and doors are now affordable."

"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."

"I had a list of 4 tasks and an expectation of cost; 4 tasks complete and cost expectations met. Very knowledgable in his field and gave good advice on future tasks such as security camera installation (which he does a lot of) and door bell/camera systems. I would use him again and seek his advice on future tasks. ts"

"I just had him come out to hang up a couple vinyl shutters on my second story. There were some issues with the shutters (not his fault), and he was able to work around that and get them hung securely."

Security Doors questions, answered by experts

There are a number of ways to secure windows. You can add motion detectors or window sensors to detect movement and impact or change the window locks to make them stronger. Some of the ways you can secure windows are much like how you secure a home: closing the curtains at night and setting up security cameras outside so you can monitor your property even in your absence. 

Not all security systems are equal, so familiarize yourself with the many features available and any associated costs. Decide on a wireless or wired system and look at monthly subscription fees to access the service. Finally, read plenty of reviews to check out the efficacy of your intended security system.

Grounding is a great first step to prevent electrical shock, but you can take it further with GFCI outlets and AFCIs (arc fault circuit interrupters). In particular, AFCIs help protect against the type of electrical arcs that cause fires, like if a mouse chews on a wire or your laptop starts overheating at the wall. These are required in some areas of your home.

Options include wired or wireless systems with night vision and motion detection.

DIY is possible for wireless cameras, but professionals ensure optimal angles, security integration, and network stability.
