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."

"Completely disappointed with the terrible service I received. I called for an inspection for my furnace and the technician left the sequencers unscrewed and the furnace left open when he left. I had to put everything together after he was gone. -He told me I had a refrigerant leak without even checking for leaks. I had to locate the leak myself. -Tried to tell me my furnace wasn't registered for warranty (when it is). -He quoted "around $3000.00" to purchase sequencers and check for a leak. (Sequencers are anywhere from $30-$70 apiece). -Charged me $99 and didn't even provide a receipt or write up for what was done. I called to ask for my receipt and it took 5 days to finally get it. -I brought up several of my complaints to the service manager and he denied them and said his technician disagrees and wouldn't lie to him. -If you are looking for a reputable company to handle your HVAC needs, please look somewhere else."

"This is the 2nd time we've hired Dan, this time for several hours of help getting us started on a DIY kitchen-backsplash project. Dan arrived on time and did a great job covering all the bases we'd hoped for: initial prep of the area (including wrapping the sides of switches and outlets with electrical tape); planning how to run the tile; mixing mortar; wet saw operation (we supplied the wet saw in addition to the tile and tile-related materials); applying the tile; and cuts around outlets. At the end of our time with him, we felt confident enough to tackle the rest on our own. We've since finished (now ready for grout) and really pleased at how it's turned out. Thanks Dan!"
