Too bad I paid him. I filed this complaint with the BBB, which he is a member of, and he refused to respond. After having another company remove all my rotted wood flooring after a slab failure I hired them to prepare the floor for carpeting. He said he would scrape off the glue residue and sand the concrete. He would then use Hydroban to put a water vapor seal on the concrete. He knew I was going to do this job in two parts. I wanted to make sure the water vapor seal would hold before installing the carpet, just in case it leaked again. On 3/22/22 His employee scraped the glue, sanded the concrete and then applied 1 coat of Hydroban. He was going to leave but I told him I knew 2 coats needed to be done. He checked with his boss and came back to apply 1 more coat. I asked if the floor had properly dried before he applied the next coat and he stated it had. It was only 20 min. in between. I was beginning to realize the employee did not know what he was doing. I later noticed that I could see the old staining on the concrete through the 2 coats and there was a white small hole, about the size of silver dollar, in the middle of the floor that had no product. I messaged Dennis and he said he would send the employee back when available. I contacted Hydroban to check on how long I actually could wait to walk on it and then found out that the entire job had been done wrong and it was never appropriate to be used with carpet, vinyl or wood flooring to begin with. Only a cement based product such as tile. I called Dennis who then called and spoke to Hydroban. He called me back with information about a product, Drylok, that he would use to redo. We discussed when he would return. He said it would take about 1 and half weeks. After waiting, I called, He started not answering my calls, not opening my txt messages for days. He finally called with multiple excuses. Then he txt's me on a Sat. 4/16 am I available Thurs. or Fri. the upcoming week. I said Thurs. Txt me on Tues 4/19"I will call you this afternoon and go over everything with you." Still waiting. The pictures are what I am left with . Mistakes do happen, it is how a company responds to them that makes them good or bad. read more
