Owner
Mike Henandez, the owner, sealed our 3 car garage floor in the timeframe he said he would, however he left about 20 drips on our driveway.
I called and spoke with him and said he would come by and clean up the mess. It rained for a few days and he never called or came by. I called and spoke with him again and he said he would call the following Monday. He never called or came by. I called and left him a voice mail and haven't heard from him since. DO NOT use this guy or his company!!! BAD NEWS.
BTW: we live in the same neighborhood-he's my neighbor.
