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."

Named 2015 Long Island's Best Garage Door company!

"Freeport Garage Door is HORRIBLE! Don't go here unless you want to be treated rudely and given sub quality work My garage door came off it's track, "Karen" the alleged owner, sent out a technician, Erik whose sub standard work only lasted hours after his poor attempt to repair my door. When I called that Karen on the Wednesday before Thanksgiving she lied and said her store would not be open until Tuesday... I called Monday to leave a voicemail and that Karen assistant. and older raspy sounding woman said, "Yes were open for business". I started to tell her about the issues with their sub quality work.. the door off the track, the lock their incompetent technician, Erik installed, could not be opened with extra keys I had made at a licensed locksmith. The older woman started a conversation with that Karen who later got on the phone with her nasty attitude and rude disposition. At this point I was frustrated and annoyed with her lack of respect. My 90 year old mother pick up the phone to disarmed the situation and that Karen told her she would call her back in the afternoon for a another technician to come out.. that was Monday, November 28, 2022 at 1pm.. it's now Tuesday and we'er still waiting for that call. I truly believe in supporting local business, but when customers are given sub standard work and charged top dollar than met with disrespect, and lies then they don't deserve to have well paying customers. Don't use this place, we deserve better when there is other companies who want our business and treat you with respect."

Locksmiths questions, answered by experts

First, maintain composure and avoid forcing it further. Inspect the key to see if enough material remains exposed for extraction. Use pliers or tweezers to grasp and gently pull out the broken piece if possible. Lubricate the keyhole with a graphite-based spray to aid removal. If self-removal proves challenging or risks damaging the lock, seek a professional locksmith's assistance. They possess the necessary tools and expertise to extract the key without causing damage.

Rekeying should be done when employees leave or keys are lost, while replacement may be necessary for outdated or damaged locks.

Locksmiths typically recommend using a dry lubricant, such as a Teflon-based option, instead of the popular oil-based lubricants you can purchase at almost any store. Dry lubricants leave a non-stick, water-repellent coating instead of attracting more dirt and debris like an oil-based lubricant. You can find these at a hardware store; some are made explicitly for lock use.

Door locks should be changed roughly every seven years. The average lifespan of a door lock is seven to 10 years, so it’s best to err on the side of caution and change them early, especially if they are showing signs of wear and tear. Examples of deterioration include visible rust and difficulty opening or closing the door. Some locks can work safely beyond 10 years, but it depends on how often they are used and whether they are exposed to damaging environmental conditions like precipitation or extreme temperatures.

If you also have a standard door leading to your garage, install a robust deadbolt lock and reinforce the frame with security plates. Then, secure any windows with shatterproof glass or film to deter break-ins. Consider a smart garage door opener for your car entrance, enabling remote monitoring and control through your smartphone. Motion-activated lighting around the garage to deter intruders is a great way to amplify these security efforts. Lastly, educate your family on security practices, such as keeping the garage entrances closed and locked.
