# How to Fix a Sagging Floor in a New Home
A sagging floor in a new home can be a discouraging discovery. Sagging may be due to damaged wood, a sinking foundation or moisture damage to the joists. Sometimes, excessive weight can cause sill plates to break. You can raise the floor with a hydraulic jack. This is a big job that may take more than one day. It is a good idea to have your foundation checked by a professional before attempting this repair. Jacking the floor up will not help if your foundation is crumbling.

2
Fix the rafter ties to two strong joints on the underside of the floor.

3
Place a large wooden column directly underneath the beam attached to the joists. Secure it to the floor with masonry screws.

Position a 1/4-inch steel plate onto the large wooden column. Place the feet of a set of hydraulic jacks onto the metal plate.

Lift the jacks only an 1/8-inch per day to prevent cracking or buckling of the floor.
