Fixing rotted floor girder.

Support the floor joists and or any concentrated loads the girder carries with jacking timbers set under the joists on both sides of the girder. You may have undersized support beams support posts that are rotting and losing their structural integrity or undersized post footings that are settling.

Sagging floors doors that won t close and cracks that appear in interior walls can be symptomatic of a more serious problem. The following steps will help keep the wood in your house dry so fungi don t have a chance to set up shop. Raise these jacking timbers just enough to relieve the load on the girder. Once in place the floor can be jacked up in an attempt to lift the floor back to a level position.

It s easier and much cheaper to prevent rot rather than fix it. If only a few joists are rotted primarily at the bottom they can be repaired using a process known as sistering after the rot is cleaned away and the timber treated to prevent more problems a new joist is laid beside the old. If joists or floorboards are nailed into the beam cut the nails with a reciprocating saw before you try to remove the beam. Stepping through the floor was not the first hint that it had rotted out but it sure moved the floor repair up on the priority list for a house with plenty of remodel projects to do.
