Mine is a rowhouse/townhouse with party walls on either side with neighbors attached.
Both of the adjoining houses have had the concrete pad in the basement redone, because they were sinking. I have not had this done, and mine is also sinking.
I was told, but cannot confirm, that there is a stream that runs under these houses. In the back, which is all concrete, I can see through an expansion joint that there is nothing under the concrete for several feet -- a big hole I suppose. I'm thinking that's the case under the sinking concrete slab in the basement. The foundation seems ok, however.
Now for my problem: I am hearing scratching, scurrying, gnawing on wood noises in the front exterior wall which has stone a few inches behind it (no insulation). I see no apparent entry points for a squirrel on the outside. I've mortared up the outside around the steps and where the concrete meets the house, several weeks ago. Are these buggers coming up from beneath the house?
I've taken off 3 feet of drywall and I can see there are gaps between the bottom stud and the stone which go down into... somewhere. I've stuffed metal screen material in there and mortared it closed. I put a snap trap in there, no takers. Is it worth doing the other 12 feet in a similar manner?
Thanks for any assistance, and my compliments on having this great board!
