"I have hired Permaseal to fix my unleveled patio concrete floor that was and still causing rain water to get to my basement, I have paid them $2,014.33 as down payment, they showed up one month later for the job, which is injecting foam under the concrete slab to lift it back to its original correct level. I came back home that day to find out that they have left and that the concrete slab was not only still unleveled, but they cracked it and patched it on multiple locations. I have called their customer care number more than a dozen times in attempt to understand what is going on, and on each occasion, I was told that the project manager was going to contact me back, which never happened until i made the next call, They have finally explained to me over the phone that it was the best they could do and that they could not fix my patio floor. I asked for a refund and did not hear back. I have documented pictures of before and after showing that the job was not done and cancelled the check with the remaining balance. I have not heard anything back from them since then, until i started getting debt collectors' emails on December the 5th from a business called FCR Services."

"I really appreciated the professionalism and detailed execution of the job from the ARC team. We worked with David on the proposal and planning process and had Gustavo, Geraldo, and Gomez do an incredible job on the installation. We are happy to report through these first few large storms of the season our house has felt nice and toasty. Would recommend ARC for others in the future."

"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."

"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."
