"**"Do not contact him?he?s a complete scammer and unlicensed. I was looking for an air testing service on Angi, and he called me. I explained over the phone that our newly renovated home had a strong chemical smell, so we wanted an air quality test. He said he could do it and asked for a deposit. About 15 minutes after I paid, I double-checked with him about the testing details, then he told me that he didn?t have the equipment to do the test. Then he refused to refund my deposit. First, he never mentioned the deposit was non-refundable. Second, the cancellation was entirely his fault?he suddenly claimed he couldn?t do the test due to lacking the tools. This is outright fraud: he took my money, won?t return it, and can?t even provide the service. I?ve already filed a complaint with the BBB. Everyone, beware of this scammer!"** "

"Mold Warriors cared more about eradicating my mold - than I even did - and didn't stop until they found and removed every location of mold infestation. Their personal mission was to make sure my home was mold-free and they did it in a way that was remarkably professional, competent, responsive and successful. The first and only call I'll ever have to make with respect to mold infestation in my house. Can't recommend Patrick and Mold Warriors highly enough."

"Project Lead: Ben The Job: Rooftop Deck above garage needed to be ripped out and replace, new drainage needed to be installed The Good: Ben was very enthusiastic about the job and is a very nice guy. He made sure to explain what the job would entail, what needed to be done, why the problems were happening, ect. He was understanding about the funds for the job being locked up until the sale of one of my other properties went through. The beginning of the job went great, the framing was done well, more ceiling beams had to be replaced than originally thought which they did for no extra charge and they had some higher quality top layer material left over from another job that they used at no additional cost to us. The Bad: Going back to the demo part of the job, we were told that there was no need to move the boxes and various other things we had in the garage out or to cover them. Nobody covered them and so now we have boxes full of plywood debris from ripping up the deck. After the initial large work was done, a team was no longer sent out to do the finishing work. It was one guy, who came out 2-3 times a week, and we rarely got any notice on what days those would be. Often we were told he would be showing up one day, but then no one would show up with no explanation. Repeatedly we were told “oh, the guy is going to come out and finish the job on x day”, but then no one would show up, and when he did the job was not finished. We were told the job would take 10 days (and that that was estimating on the long side). The job was started on March 29th and didn’t finish until May 19th. It happened several times that Ben asked if I was free for him to come and discuss things later in the day, but then he would be a no show. There was a general lack of quality control with the finished work. Instead of quality control being done by the contractor, I had to go and find all of the problems myself (of which there were many on the first pass) and complain about them. Then the one guy came out a week later to fix them, but then new things came up, and I would have to complain about them, ect. In the end I just kind of felt it was ‘good enough’ and was so exhausted with the back and forth and taking time out of my work day to inspect the work and discuss what was wrong I just said it was fine so I could go on with my life."
