Im an experienced general contractor trying to help out a good customer . My question is how do I replace a rotted sill plate on concrete slab? The home is a 2 story split level home in central New Jersey. I do mostly interior remodeling though i have taken on some pretty big exterior projects ( 8 section modular home , 2 story garage , 700 sq ft wrap around porch , I have some experience replacing interior beams and porch posts which require jacking up parts of home still this seems a bit out of my reach . The home has asbestos siding down to grade and a recent walkway replacement revealed rot along the back of home where previuos concrete side walk met home at just below slab. The side walk pitched in towards home. Paving contractor pitched new walk away from home,I know this will help shed water away. There appears to be no sagging or structural problems along back of home, no sagging roof line , cracks , and all doors and windows are operating ok. Still there is significant rot there and it appears to me the home would need to be jacked up slightly to replace this plate .
