You will find many businesses here that will replace your door with a nice new retrofit door. If that is what you want, you won't find one here. We specialize in repairs. If you are like most people, you just want a door that does what it's supposed to do. !!WORK!! That's where we can help. It doesn't take a genius to fix a door, but it does often take a strong back, a certain amount of risk(glass breaks), and some knowledge of the subject, along with at least 1 trip to the hardware store(often more than one). If you are the type that wants to tackle it yourself, we would be glad to offer advise where possible. Most people have better things to do with their time. Leave it to the experts.

"We had 2 sliding glass doors that wouldn’t glide freely. I got a phone quote & repair on the same day! They now function perfectly & the price was so reasonable!"

Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

Locksmiths questions, answered by experts

Rekeying should be done when employees leave or keys are lost, while replacement may be necessary for outdated or damaged locks.

As with any computer, smart locks can be hacked by someone with the technical skills to do so, but most people do not have that ability, making smart locks relatively safe. If you have any concerns about a compromised smart lock, opt for an encrypted smart lock, change your Wi-Fi password, and make sure that you only give out your password to trusted family and friends.

There are many types of deadbolts, but these tips work on most. First, address any grime buildup. A bit of WD-40 will loose up rust and dirt so the deadbolt can turn. Inspect the door and frame alignment if this doesn't resolve the issue. Adjust the strike plate or the deadbolt's position to improve alignment. If the problem persists, disassemble the lock to inspect for damaged or worn parts. If you are unsure how to do it, hire a local locksmith.

While a strong conventional deadbolt offers enough security for most homeowners, if you’re looking for extra features beyond just simple locking, smart deadbolts are the way to go. Smart deadbolts allow for keyless entry using your phone or a code, remote access in case someone is locked out, and features like temporary access codes, automatic locking, tamper alerts and entry-exit monitoring. Smart deadbolts also come with downsides: they rely on batteries and wireless networks and are potentially vulnerable to hacking by skilled home intruders.

In some cases this is possible, but it’s not advisable as the screwdriver is likely to leave marks all over the wall and a noticeable dent on the door. Move slowly and carefully if you have to use this method, and consider calling an emergency locksmith right away instead of trying to break in.
