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 don’t think there are enough characters available to explain how badly they lied and misled us. I called with one specific purpose, which I was very clear about. I have stained fascia, and I wanted to know the cause and then have it repaired. The owner and another contractor explained that they would remove the fascia to identify the cause, which could be my gutters. The estimate was based on what was likely the cause, but I was assured multiple times that they would remove the fascia to confirm. so I signed the estimate. They repaired my gutters and left without removing the fascia, which was the sole reason that I contacted them. When I questioned it, they said their estimate didn’t say that, however, we had a clear verbal agreement, which they violated, and offered to do the actual work I wanted from the beginning for $500+ more after I paid $1100 for something that may not have been necessary. I’m filing multiple complaints and citing Unfair, Deceptive, Abusive Acts and Practices (UDAAP)."

"It’s not often that a reviewer praises a contractor for what he DIDN’T do. Austin Ireland, the owner and operator of Drytek, didn’t propose spending several thousand dollars on encapsulating my wet crawl space. He said that in my case encapsulation might not be cost effective. You see, my 50 year-old home’s foundation consists of 8”x 8” wood posts, with the foundation’s perimeter enclosed by 1”x 6” boards, slatted to allow for ventilation. The layout of my irregular crawl space posed other installation problems as well. Among other things, insulation panels would need to be installed to form walls in addition to the vapor barrier and a large dehumidifier. Four contractors/salespersons preceded Drytek’s Austin Ireland. One simply said there’s nothing that can be done. Another proposed encapsulating the crawl space from the OUTSIDE, but thankfully never followed up. Another did an evaluation, but never returned my calls. Dryzone wanted $8,500 but offered a pressure tactic $425 discount if I signed a vague contract the same day the salesman came. Later the salesperson said the installation of insulation boards would raise the cost significantly. The salesperson at Dryzone also said he would call back with details, but didn’t. Drytek’s Austin Ireland, on the other hand, took more time than any of the others to carefully examine my crawl space. I crawled with him as he pointed out the condition of my crawl space and the challenges of encapsulation. By this time, my own research had better prepared me to better evaluate proposals. I found him to be knowledgeable, straightforward and honest. I was a highly motivated prospective customer. Last year a HVAC system had been installed with the air handler, electronics, and ductwork in my crawl space. The moisture in the crawl space last summer was degrading the new system. So what did Austin Ireland of Drytek propose? Four centrifugal snail fans joined together by extension cords, placed strategically in the crawl space. These are not exhaust fans to ventilate, but rather air movers like you may have seen in public bathrooms to dry floors. He even showed me what to do, and wouldn’t take any payment for his visit. After investing $400 the next day at Home Depot , I located the fans, connected the extension cords to the receptacles in the fans and waited for the heat and humidity to test Austin Ireland’s theory. It is now six weeks later and we have had three prolonged periods of hot, humid weather during which I have activated the fans. THE CRAWL SPACE HAS STAYED AS DRY AS A BONE. Amazing! The vast majority of wet crawl spaces need to be encapsulated; mine did not. But it took a trustworthy expert whose ethics mattered more than profit to present the best solution for me. Austin Ireland, owner and operator of Drytek, is that person."
