Methods For Fixing Sagging Floors
When dealing with old houses, sagging floors are a common issue, but the good news is that there are effective methods for fixing them. Let’s explore some of the most reliable methods for repairing sagging floors, including jack posts and support beams, replacing joists or engineered joists, and lifting and leveling with polyurethane foam.
Jack Posts And Support Beams
Using jack posts and support beams is a traditional method for fixing sagging floors in old houses. These temporary and permanent support structures help redistribute the weight and stabilize the sagging floor. Typically, brief jack posts and beams are installed first, followed by permanent ones over new footings.
Replacing Joists Or Engineered Joists
When the existing joists are severely damaged, replacing them with new or engineered ones becomes necessary. This involves carefully removing the old, sagging joists and installing new ones capable of providing the essential support and leveling for the floor.
Lifting And Leveling With Polyurethane Foam
Another modern method for fixing sagging floors is the use of polyurethane foam. This involves injecting the foam beneath the sagging floor, which expands to fill voids and lift the floor to its original position. The foam’s expansion and curing properties make it an efficient and accurate method for correcting sagging floors.
Costs And Considerations
When fixing sagging floors in an old house, it’s essential to consider the costs and potential impacts on the home’s resale value. Repair options may include installing temporary jack posts, support beams, and permanent posts with new footings.
