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."

"I called to set up an estimate on a Friday which was scheduled for the following Monday. I was considering both attic and wall insulation. Mark arrived Monday on time and confirmed with texts as follow ups. He quickly determined that I already had some insulation inside my walls and evaluated my attic space. He said there wasn't much and was likely the original insulation from when the house was built in the 1960s. The estimate came in at just over $1000 which was quite reasonable based upon similar quotes I had read online for similar sized houses as mine. It would also bring the insulation level to the recommended level by PG&E, just above code. When he looked at his team's schedule they had an opening the next day in the morning which worked out quite well for me. The team of 3 arrived on time and the job was completed with an hour to go of the allotted time. I was told that I should easily notice a difference as what was there was not much and the results would seem to be "night and day" compared to what I was used to. True to this claim yesterday (first day of summer 2018) was the first real test of heat with Concord peaking at about 105̊but inside was a good 20̊cooler than outside keeping the inside of my house much more comfortable than previous to my insulation upgrade. I was waiting for such a result before posting this review. I highly recommend All Seasons! Thanks guys!"
