This house is 100+ yrs old. The back wall was buried in dirt and built up gravel. Moisture rotted the sill, band joist, bottom plate and some of the vertical members. Also some of the foundation wall needed repair. We have repaired (see photos of current state) and now we will put siding back on, but how to flash since the rest of the wall is just siding on studs with bat insulation between? This is in the mixed humid climate of central NC. Thank you!
