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."

"job was done in a timely manner, however was not done in a professional workman like manner, Which the contract states it would be done. When the estimator came he explained what would be done to eliminate water issue. When we asked how does water get removed outside and how they would undermine stairs and walls he simple stated the installers will go over that with you when they come. The installers said they would be channeling under the step and walls, which are only 2 1/2 inch walls. The last step was also a simple channel as well. More time consuming perhaps, when you charge $3000.00 more than another contractor, homeowners are believing they are getting a professional job! They cut her stair runner instead of peeling it back so it could be glued back down. she needs replace whole runner now and company could care less including there estimator! sheetrock replacement also more expensive because took a hammer to the walls instead of saw zall,nice straight lines! also have photos."

"I AM LIVID WITH THEIR SERVICE. My husband and I have been living in our home 4 years without a single issue with our cooling system. We had UGI come out to "service" our system and said everything looked great....2 months later something with our compressor blew...that was $400. Then this morning, less than 30 days later, we apparently needed a brand new thermostat.....another $400 and guess what? MY HOUSE IS STILL NOT COOLING DOWN. So I called and said how it is absolutely ridiculous that there is still an issue especially after charging us to "fix" the thermostat. I am obviously frustrated. I work from home, its hot and I am pregnant with 4 pets in my home that are distressed from the rising heat and their customer service agent has the audacity to be BEYOND RUDE and tell me "to have a better day" as if it was MY FAULT...ok. It is very odd that ever since they came to "service" our central air system they've had to come back THREE TIMES and the system STILL NOT WORK. BEWARE!"

Insulation questions, answered by experts

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.

Unfaced wall insulation is easier to cut and install, making it the better choice for a DIY project. It’s also more affordable. But if it’s unfaced, you’ll likely need to add a vapor barrier to reach your desired R-value and efficiency, as it doesn’t offer any moisture barrier.

Faced insulation uses paper or foil to create a built-in barrier and doesn’t require an extra step. It’s also more fire-resistant and safe. But it’s quite a bit more expensive and a little bit harder to work with as a DIYer.

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

Faux wood garage doors provide the best insulation for garages. This style is commonly insulated with polyurethane foam—a thermal conductor—that retains heat and keeps you and the inside of your garage warm.

Natural fiber batts and spray foam insulation both work great for soundproofing. Newer materials, such as hemp batts, are more expensive but more effective for insulation and sound blocking. They are also more sustainable. There is also a professional system called Blow-In Blanket Insulation (BIBS) that is soundproof and moisture-resistant. However, BIBS must be installed professionally and can be a costly investment.
