Start with what has to come out
Older Madison County attics can hold insulation damaged by pests, roof leaks or decades of settling. We remove it before adding foam so the new layer bonds and performs.

Retrofit Spray Foam in Hull: FAQ
Can spray foam be added to an older home without opening walls?
Yes, in reachable areas: the attic roof deck, knee walls, rim joists and crawl spaces. Closed wall cavities are usually left alone unless they are being opened for a remodel.
Do you remove the old insulation?
When it is wet, contaminated or in the way of the new work, yes. Insulation removal is one of our services.
Is my Hull home too old for spray foam?
Rarely. We check roof decking, ventilation and moisture first; some older homes need repairs before foam, and we tell you if that is the case.
