I spent a small fortune with Quality 1st when I bought my current home. I hired them to waterproof my crawl space. About three years later, my neighbor noticed that water was flowing from my property onto his. The waterproofing had been done incompetently, and the water was sent in the wrong direction toward my neighbor instead of out (per code) toward the street. They came out to fix it, but apparently they didn't fully check it and so did not repair the issue correctly or fully because serious damage had been done that I did not know about at the time and that was not addressed or even revealed by Quality 1st when they came out. I just sold my home, all packed and ready to move, thinking everything was fine. The buyer's home inspector discovered my "waterproofed" basement was wet and FILLED with mold, and all of the rafters had rotted. This was because Quality 1st did an incompetent job (according to everyone so far who has come to assess it). The water that was going to my neighbor's property was apparently recirculating right back into my crawl space. Also, I found out from contractors who came out to give me an estimate on cleaning up the mold that the one sump pump Quality 1st said would be sufficient would never have been acceptable for the square footage. That's what I got for more than eight thousand dollars. I lost the sale of my home, and it's a huge mess. Now they will not pay to fix this mess. Now I have to get an attorney. BEWARE!
