The Rockweiler men spend a good deal of time installing chutes, foaming ceiling holes, fixing the bathroom ventilation tubing, installing foam board over the kitchen and bathrooms, and fixing anything else that was allowing warm moist air to move into our attic. They then blew in a foot of insulation. Before they started they covered steps and hallway with drop clothes [and] then vacuumed -up pieces of loose insulation. I am happy and impressed with the work done.
