"We were not locked out, but our key only worked with great difficulty. We called late Saturday night and he came on Sunday. No one else answered the phone or even called me back.

Guardian Protection
Guardian Protection
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."

"Art and Shawn were both thorough and methodical, from the deconstruction of the existing cabinetry to the building of shelves to fit a custom space, to installation of floor tiles, the work was careful and top notch. There were some unexpected hitches (one involving rehanging a door) but they handled those well. They also took the time to find a close as possible a match to our existing ceiling molding (which is no longer made as it is from 25 plus years ago) and reused as much of the existing lumber as possible. Terrific all around job. Very happy with the result."
