Insulation removal involves vacuuming any old, existing insulation out to provide a fresh canvas for your installer to air seal every air gap in your attic without the extra labor and risk of missing areas that comes with working around existing insulation. But that’s not the only benefit in doing a spring cleaning of your attic space.Attics commonly attract pests of all sorts. Rodents, insects, bats, and even raccoons can sometimes take solace in your attic space if they have the opportunity. They leave behind excrement, disturb your existing insulation, can destroy baffles and generally leave your attic in disarray. If your attic has not been air sealed, these contaminants can make their way into your indoor air.Very old homes can also be outfitted with outdated, settled, or damaged insulation that isn’t performing to its best ability. Getting a clean slate can help improve your attic’s efficiency to a degree that just adding additional insulation cannot.
