You don't want him working at your home. He does not show up on time, leaves frequently because he does not anticipate what the job requires, does not finish the work and frequently has to redo what he has done because it will not pass inspection. I had 2 leaks in the gas line that he ran for me that was found by a contractor I hired to finish the work that was started and a sky light that was only sitting on the roof.

We can't recommend Kevin highly enough. He added a new bathroom to our home and did it during Covid with all the health precautions. It came out better than I could have imagined. We passed all inspections on the first time and work area was always left clean.
