"SafeStreets’ alarm system is fantastic. The motion sensors, door/window contacts, and cameras work flawlessly. The home automation features are a huge plus—I can control everything from my phone. Highly recommend SafeStreets to anyone looking for reliable security."

"I had my storm door replaced by Byers security. Mike and Paul did a fantastic job installing it. They took their time and the door fits perfectly. Looks great. Mike was in touch with me throughout the purchasing process. Great company to deal with."

"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."

"Have used Joe 3 times now. First to replace 4 exterior doors. Second to refinish some interior paint and trim. Lastly for a complete kitchen remodel. Each and every time he was prompt and very professional with great attention to detail. He has a permanent place in my address book and will certainly be called on again, probably sooner than later."

"Terrific, we decided to go w/ Stoneberger because their sales representative spent time advising and guiding us through the options, the colors and styles of doors. She listened to what we thought we wanted and helped us find the right solution. No other sales rep we met with offered that customer service. She also followed up on time and was super easy to work with once we decided on specific doors. Installation also was on time, efficient and went very smoothly. We had one issue that arose b/c of the age of our house and Stoneberger addressed it quickly and beyond fairly. Highly recommend them."

Security Doors FAQs, answered by experts

There is no “better” option, as it depends on your personal preferences and home’s needs. Wireless systems are much easier to install, making them DIY-friendly. Wired systems offer a more reliable connection that is not tied to a router, but they typically require professional installation.

You likely can reset your house alarm without the code, but it depends on many factors like how it’s wired and whether or not there’s a default reset code. Most companies make bypassing a security alarm without entering your code challenging to prevent burglars from simply resetting the alarm during a break-in. Your best bet is to contact your alarm company directly to get specialized support for your situation. 

But, while you wait for support, you can disconnect it from the power source to stop the alarm from going off.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

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

Standard residential deadbolt locks come with a steel bolt that locks your door into place using a key (or keypad) on one side and a thumb turn on the other. When you lock it, the bolt slides into a strike plate on your door jamb to secure your door shut.
