This crawlspace needed rodent infested insulation removed & replaced. While we were there we air sealed the perimeter rim assembly to shut down the air & pest infiltration. Copper wire mesh is stuffed into any cracks or crevaces 1/4" or greater before we apply closed cell spray foam 2" to 3" to the whole face of the rim joist, overlapping the sill plate, & onto the top of the concrete foundation wall. This prevents rodents from chewing through the spray foam. We also bagged and disposed old building materials and clutter. Then we installed an isulation barrier to help keep the air clean and free of fiberglass particles - especially with the wine cellar's air conditioning unit pulling air from the crawlspace. Lastly we HEPA vaccumed the horizonal surfaces creating a clean storage room for the new owners.
