    Foundation Repair in University Place, WA

    Like many homeowners, the couple who owned this home in University Place, WA had never ventured into their crawl space. They assumed everything under their house was excellent, and their floors had adequate support. When they reached out to TerraFirma to inspect their crawl space for water damage, our System Design Specialist volunteered to go into their crawl space to check their support posts. What he discovered was that one of their posts was 5 inches above the ground. You'll notice to the left of the post some wood that appears to be debris. For years, that debris was the stop gap between the support posts and the footing. Eventually, the debris shifted enough to fall away from the post. In a day, TerraFirma removed the old post and installed our SmartJack support post, which is made from galvanized steel and can support more than 60,000 pounds.
