"Last weekend had someone pry our side door open to our exterior garage and the ADT door sensor picked it up immediately. The alarm siren was loud and scared the person off. Someone from the response center called within 30 seconds. We’re fortunate that the security system did what it is supposed to. Feels like we made the right call going with an ADT security system."

"Rafael was great - he fixed our front door knob and lock, replaced another door handle, and our towel bar. He worked us into his busy schedule and came by on a day that was best for me. Rafael picked up parts he needed at Home Depot after assessing what we needed, and efficiently completed all three jobs."

"Great company! I needed to replace my regular door and security door. Valentino (the owner) had come by for a free assessment and estimate. He provided a fair assessment without being pushy which I greatly appreciated. The doors were custom made according to the specifications I had chosen. The crew that came by to do the installation were friendly, professional and were respectful of my property. As part of the installation of the doors, they also had to do new jambs and the bottom (I previously had a half step). The end result is absolutely beautiful and I am so happy with my new doors. They are well sealed when closed and I no longer have a draft. I highly recommend Custom Windows & Doors!!"

"So far great. I called for an estimate, the sales guy wanted me to purchase of course but wasn't overbearing. We got the system shipped to us. This is a DIY install, so just know that going in if you buy one. Also, there is a one year or 3 year contract, and if you want out of the contract, you will pay 80% of the remaining contract. The sales guy was very upfront and clear about that. If you move you can take your system/contract with you, or transfer it to the next homeowner. There are videos you can watch about installing, as well as a manual -- took a little looking on the website but there are multiple helpful manuals, call and ask if you can't find them. Also, calling the tech guys for help was easy, I was able to get through with little or no wait, and they were patient and very helpful each time. Having never installed a security system, it took us an evening rather than 15 minutes, but we have old doors that are not flush with the jams and needed to figure out how to line up the door sensors.That, and figuring out where to place the motion detectors, was all that really took time, it wasn't too bad. The base unit worked fine from the start, the voice has a pleasant British accent when "she" talks to you. You can arm your system and disarm with their keychain remote, but that left us unsure whether the system was in fact armed. (Couldn't hear the nice British voice through our door). Using our mobile phones seems better for us, the package where you can use your phone does cost $10 more per month but seems worth it to us. I did look into another very similar DIY system from another company that was less per month with no contract, and read many reviews. It seemed that other's experiences with customer service was sometimes good, sometimes not, and some had good experiences with the equipment, some didn't. We decided Front Point is worth the extra $ rather than take a chance. As far as cost, we got 2 door sensors, 3 motion detectors, base unit, stickers and sign for $99, our monthly fee is $45 with a 3 year contract."

Security Doors FAQs, answered by experts

Yes, it’s possible a burglar can get through a deadbolt. Some types of deadbolts are harder for an intruder to get through, though. For example, a single-cylinder lock only requires breaking a window nearby and simply turning it. While other locks, such as a double-cylinder lock, may offer greater protection and make it harder for an intruder, no deadbolt is 100 percent effective.

It is possible to spend only $30 on a camera that can cover one particular area. You wouldn't need to buy software, hardware, cables, or anything else. Instead, it would connect wirelessly to an app on your phone where you could monitor the feed and take necessary actions at your own discretion.

Yes, evaluating needs based on home size, layout, and climate.

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. 

The biggest downside to a wireless security camera is that it's 100% reliant on Wi-Fi to capture footage at your home. Even when Wi-Fi is reliable, the range for wireless cameras may only be 200 feet or less. Drywall, brick, and other materials in your home can be enough to make your signal lag.
