And when your friends marvel, you don’t have to tell them that replacing mobile home floors isn’t really that bad! Typically, floors settle near the center of the house because the perimeter walls are constructed over a sound, deep foundation and settle very little. Major support beams within this perimeter, though, are often supported by makeshift posts. To fix sagging floors while strengthening the entire surface, install blocking between pairs of joists.
Check your local building codes, but generally, joists should use the following guidelines if they are spaced 16 inches apart. If your joists are indeed too small, see some of the methods below to firm them up. After detecting the source, the first thing you need to do is fix up the leakage. Check alongside the saggy floor if there is any moisture leaking out.
Improper holes and notches from alterations and running service lines are a major source of weakened joists. Generally there should never be any cuts or penetrations in the middle third of any joist, or anywhere along the bottom of the joist. Notches at the end of a joist should not exceed 1/4 of the joist depth. Center notches should not exceed 1/6 of the joist depth. Holes should be a minimum of 2″ in from the top or bottom of the joist, and no larger than 1/3 the depth of the joist. Press it up against the bottom of the floor and hold it temporarily in place by wedging vertical 2-by-4 supports under it as shown.
If the beams are rotted you a getting out of DIY territory. You’ll need to build a wall 90 degrees to the broken joists. Jack that up 1/8” per week till level then sister and support again.
