"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."

"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."

"I have had Cransten Smart Security for about a year now and I just want to say how much I love the Camera quality. All of my neighbors with their DIY systems can't make out anything. Ours can make great detail at night time. Plus there is no service contract!"

"Brent and his team repair a sliding door and sliding screen door which were not operating correctly including some wooden trim on the sliding door. They also caulked all doors and windows at our house. They were not weatherized by the builder. The work looked great and the doors now slide with ease."

Customers say: Terrific value

I am operating the same ‘one man’ company I formed in 2006. That's when I started helping homeowners here in Denver thru HomeAdvisor (when it was called Service Magic). I am especially proud of working with a large array of wonderful and talented individuals in all walks of life! Many of my clients know me quite well and have found no surprise in why they have chosen me to be their main ‘go to guy’ for quite a long time; and some from the beginning years. Thank you goes out to everyone who has partnered with SHH for their home maintenance needs . I have remodeled kitchens and baths but primarily stick with smaller projects. Replaced sinks ,faucets , flooring, repaired and or replaced fence panels, all kinds of doors repair/ replacement, lots of ceiling fans, glass panes, garage door openers , toilets, faucets, and cleaned sink drains, check out a few pictures and remember to click through the (stacks) of photos. Very competitive prices and old fashioned ethics, Dwight Horner

Security Doors FAQs, answered by experts

Yes, you can install a home security system in an old house. In fact, you can install a security system in any home. Some wiring may need to be added, but most home security systems do not require a lot of additional wiring. Wireless security systems can easily be installed with minimal additional wiring, if any at all. Most wireless security systems can be monitored and controlled from your smartphone, and the cameras and sensors operate on batteries.

Some Christmas lights are marked as being “UL Safety Certified” or Underwriters Laboratories Safety Certified. This lab is a trusted source for determining the safety standards of electrical products—you should make sure your Christmas lights have this label. Brush up on other electrical safety tips before installing any lighting features. 

The best type of deadbolt depends on your specific needs. If accessibility is your primary concern, a single-cylinder deadbolt is the easiest to operate. Mortise locks are likely the most secure type of deadbolt you can install, but single-cylinders combined with secondary locking mechanisms like vertical locks are also a great option. Smart locks will give you the most flexibility to open and close your locks whenever and wherever you need to. 

A study from the University of North Carolina found that security system signs were one of the top ten deterrents for burglars when choosing a target, so they do have some effect. However, you can get into legal trouble for putting up fake signage, so it’s best only to put up signs when you have the alarms to back them up.

While all security lighting systems offer different benefits, motion sensor security lights have the most advantages and the fewest cons for the average homeowner. While the upfront cost can be hefty, automatic, motion-detected activation will reduce your energy bills in the long run by ensuring the lights are only turned on when necessary. Plus, they’ll ward off intruders and help invited guests find their way onto your property in equal measure.
