The Healthy Spaces repair team raised floor joists, did all the correct concrete pour for seven flooring jacks. They raised the floor 1/4 inch!! They will come back once a year to adjust the jacks. They were great about explaining to me how these repairs should be performed and how to make sure we minimized damage to other parts of my house. I had no cracking on the ceiling, walls, or floor. They were extremely professional and did the job in a timely manner. It took 2 days to do the job. They took pictures under my house so I could see the work they did since I wasn't about to crawl under the house!
