What to do with poorly installed open cell foam?
I have a 1200 sq. foot california ranch with an attached carport. Recently I had a local contractor downspray the attic. He agreed to take up all existing insulation and perform the downspray. After the job I dug into the foam in 3 places just to make sure he did it right. Unfortunately, I found 2 inches of our old, old fiberclass batt insulation under his 5 inches of open cell spray foam. Should I have him demo the whole thing and redo it, or should I negotiate a reduced rate? If so, should that be 1/2 off his $1600 fee, or more or less? He understands his workers messed this up and he is ready to work with me.
