Sealing siding/sheating to foundation
I have a slab on grade foundation built in 1972. It has aluminum siding with what seems to be some sort of fiberboard sheathing that doesn’t take much to crumble. I was doing some yard work and noticed the siding pulling away from the house. You can see in the 1st picture, the aluminum siding and the 2nd picture I can stick my hand under the siding and into the stud bay. Obviously, this makes my house very drafty, it also brings a huge concern for pests. We seem to have a never ending stream of ants in the spring summer which we try to treat but never win.
With all prices across the board at all-time highs – is there any temporary way to seal this? I saw a few videos where they use liquid flash to seal the sheathing to the foundation. Is is possible to remove the bottom few rows of aluminum siding, put a new OSB that is stiffer and extends to the concrete foundation, then liquid flash the new sheathing to the foundation?
I realize OSB is like 4x-5x what it normally is – we were saving to do an entire new envelope with Zip-R but that isn’t feasible until market prices drop. I figured I could buy 1/10 of the sheathing just by sealing the bottom row and re-using the aluminum siding if I can pull it off without bending it too much…
Any help is appreciated!
