I have a mild moisture problem, mostly from a leaky chimney. I am addressing this, and will be installing rain gutters in the spring to further address the issue. The floor is not well levelled and the water generally pools in two places and don't really bother anything. A dehumidifier keeps the dampness down to a manageble level.
One wall of the foundation also has a slight bulge to it, and some evidence of fungus or something growing on it in the past, though it has been scrubbed clean and nothing is there now. I think this will probably need to be torn out and replaced.
I also have a problem with settling. The previous owner did some remodeling and extended the kitchen, building over where an enclosed porch used to be. The foundation only goes to where the kitchen used to end, and because it has been protected from rain by the porch, that portion of the foundation did not settle, while everything else did. My kitchen floor has a large bulge right in the middle, about 3" above the lowest point in the kitchen.
The home is built on an extremly narrow lot, 31ft face, with only a couple feet to the property line, and less than 10 feet between my house and the homes to the north or south. I know this limits my options quite a bit.
I guess my question is, how feasable would it be to redo the entire foundation, raising the house (or lowering the basement floor, depending on outside sewage levels) and leveling it, and expanding the foundation to match the house. It would recoup about 800sq ft of space that is currently relegated to damp storage, chest freezer, etc., and I should probably address the bulging wall anyway.
Does anyone have any idea how realistic this is, and what the cost might be in extremely ball park figures?
