"This is the most negligent contractor I've dealt with in my life. They suggested to not be home for our attic insulation since we have a newborn at home which I appreciated. They seemed careful and thoughtful in the sales process which is why I ended up picking them for our project. However, when it came time for the job they were reckless with security and safety. Before the job I sent multiple notes via text and email, and had a phone call asking them to contact me at the end of each day so I could set the alarm and lock the doors remotely. Day one they didn't do this. I sent another ask to please be mindful of this so I could keep our home secure. Day 2 they did not do this again, and ended up leaving our front door wide open which triggered a burglar alarm at 2am requiring us to deal with the security company and police throughout the night. Afterwards it took days for anyone to reply. They lacked empathy or ownership for how negligent their team was. I would not recommend working with these people. Mistakes happen, but the response to these mistakes was almost as bad as their dangerous actions themselves."

"Excellently. The masons made quick work of the demo up front, taking a day to remove the parapet and half a day to get the chimneys down. The rebuild was more deliberate, getting the colors right, making sure the new common brick was plumb and the decorative brick looked perfect. Once the parapet was up, the roofing crew came in and flashed the new masonry tightly, applying reflective paint and patches to wick the water away from the brick. The roof was applied over the top brick with a slight overhang that later gets hidden by the drip tray. The capstones came back particularly beautifully. The cleanup was very effective, having red mortar meant it took a bit more detail to get it right, but they did it. The work is strong and looks good."

"Door install went well, it opens and closes and looks nice. now i just have to clean up all the dust that was left behind. literally have to mop and dust my entire first floor and upstairs. installers didn't hang any plastic. I called to pay the remainder of my bill and they agreed not to charge me the 2% credit card fee as consolation. so ... i'll use someone else next time."

"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."

"We are very impressed with the quality of the job. Steve acted very professionally. First, we liked that he provided detailed list of what could be done to enhance attic insulation, and the price for each item in it. Second, he suggested not to do insulation right away, but wait and do it after we get our roof tiling renewed. As we found later it was a very good piece of advice. We followed his recommendations, then waited a few more years for a cold winter to provide the feedback. After two winters with new insulation we are completely satisfied with the job quality."
