We have a finished bonus room above our garage which I don't think has insulation in any of the walls or ceiling, and definitely not in the floor. We'd like an estimate to have this room insulated. Also, we'd like an estimate for bringing our attic insulation up to recommended levels, as our house is almost 40 years old and the insulation is uneven.
