DIY & Home Improvement

I was just having this discussion with a spray foam guy that was doing some work on our building storage rooms.

We were discussing options for my mother in law's house which sounds like yours.

From what I gathered, injecting foam is more trouble than it's worth. He said walls buckling and bulging is an issue. He said if you really want foam, which is the best, you are better off stripping the walls.

I've done blown cellulose in a couple ceiling crawl spaces in 100 year old 6 flats. Once in our building and once for a customer. The results were great. These were crawl spaces with limited access but still better access than your walls.

For my MIL, we are considering cutting a channel in the inside drywall walls up high near the ceilings on outside walls. She has exterior face brick so going from the outside isn't feasible.
