Sagging floors in Clarion, Ia

The customer notice their floors were squeeking and wanted to have them inspected. We come out to their home and found that there were issues with the foundation supports in the crawl space. The problem the house was having was the floor support that was there was not enough to support the floor. Now the floor is sagging 3/4" and there are drywall cracks appearing. We fixed the problem by adding Smart jacks to the crawlspace to help support the load of the floor.
