“I contacted JH3 Company for an estimate on a full roof replacement, they provided me one very quickly, and responded promptly when I had questions. I was told they would schedule the work as soon as possible, but it might be a few months due to the high demand. Within 6 weeks I was given a date for the work to begin – At least 2 months before I expected. The workers were very careful and did a professional job, the roof looks GREAT. Chris was good about communicating and following up on all the questions I had. I would recommend them to all friends and family.”

“I asked JH3 Company to quote resurfacing and sealing my garage floor. Their quote was clearly the most comprehensive and reasonable for the work to be done. I contracted with them for the work and they delivered on time, to specs, and with courteous and capable workmanship. All my concerns were politely and quickly resolved. No more words are necessary: real quality workmanship, reasonable pricing, and nice, capable workers. I am amazed to find a contractor like this in SoCal. You should not be disappointed if you go with them.”
