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."

"If I could give them zero or negative stars that would be more to the quality of the work they did for me. I contracted them to install 13 windows in a brand new patio door on my mobile home. Dan and his partner were the installers and initially I thought it was just some lack of attention to detail and poor quality in their workmanship but it turned out it was completely just negligent ********! Almost every window leaked cold air when it came time in the winter and after they had finished installing everything towards the end of November beginning of December. Missing caulk lines and having the use my own insulation and drywall because of the negligent job they did. They had to come in and recaulk around almost every window and or put insulation in but I ended up doing most of that myself. The worst was the opening they left on each corner of my patio door and a few other windows and with all the rain and snow I ended up with black mold and fungus growing inside at the base of the door"

Insulation questions, answered by experts

Buying a house with vermiculite insulation is not recommended without going through a proper testing process. Vermiculite insulation can potentially contain asbestos, which poses health risks when disturbed. While it is possible to purchase a home with vermiculite insulation, you should have it tested for asbestos, and ensure proper containment if asbestos is present. If asbestos is present, you will want to hire a professional to remove it, ideally before you move in.

Insulating your basement walls offers numerous advantages that make the project well worth it. By adding insulation, you can reduce the chances of moisture damage to the house's structure and lower the odds of mold growth. You'll also add comfort to the space by reducing temperature swings and increasing your home's energy efficiency, potentially reducing your energy bills to earn your investment back.

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

Roof vents help cool a house because as they allow hot air to escape, the temperature regulates inside the attic. If vents are defective or there are not as many as there should be, the attic becomes hot and stuffy. Without roof vents, air conditioning has to work harder to maintain a consistent temperature in the attic.

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.
