Air leaks into pantry and hallway in 1890's house with finished basement
harryemattison

Hi,

My pantry is close to the same temperature as the outdoors and I would appreciate any suggestions about what to do. The basement is finished so I'm trying to figure out what to do from the outside.

There are multiple layers of old siding beneath the shingles, the inner layer of which is rotting in places. And there are various voids large enough to fit a finger.

Can I "cap" it with a horizontal piece of rigid foam sealed on the sides with spray foam? Or do I need to take off some shingles to seal it with a vertical piece of rigid foam or something else?

Thank you

I'd remove all the old siding (perhaps saving what's on top now) then rebuild with the usual sheathing and house-wrap.
What you propose will work but eventually you're going to have to remove all the old rotting wood anyway so you might as well do that now and be done with it.

What Phil said, but also insulate the wall cavities and use a vapor retardant primer on the interior wall surfaces.
