"Great service! We had a low point in our floor and needed some flooring support. We got lucky and were able to get an appointment the day we called. They came out and within a week the work was done. Steve Higa was our assessor and was very professional and nice! He followed up about a week after the work was done and stopped by to check it. If we need any future work I hope we get lucky to have Steve help us again!"
