How to replace a rotten sill plate, joists, and subflooring.
I'm going to have to study this post and take notes! I am buying a small 1950's house also that needs a lot of this sort of repair. Luckily the main wall that needs help is the north. Its a 24' span and parallel to the floor joists. The house has a gable roof, eves on E&W. Since it needs sills, probably plates and sistered ends on some of the floor joists, could it be jacked up from the outside?
I was envisioning removing some of the siding, lagging on some 2x8 beams to the studs and then jacking it up and putting in bracing under the beam as I go. Gradually work it up to about 2" above the foundation.
The house is a small 24'X32' single story on a cinder block foundation about 1 1/2' above grade with a crawl space underneath. It also has a center wall running N-S to support the floor. the E W walls support the whole roof which is stick built, no cross rafters.
Any special considerations? I was thinking about putting in some sort of barrier between the block and sill like rubber membrane or something. I was also considering digging around the whole foundation to install a drainage system and waterproof the block foundation. Plans are to eventually expand the house N&S so I may be doing the sills and such at the same time on respective ends.
