How Old Insulation Removals Are Done
Blow-in insulation simply doesn’t last forever. Most attics with blow-in insulation can be better insulated with modern insulation products. However, in order to get the best r-value from your new insulation, you need to free up the space taken up by the old insulation.
Old insulation removals are typically done by insulation contractors, but some homeowners handle the task themselves, too. The basic idea behind removing blow-in insulation is vacuuming the insulation back out of the space.
This requires an exceptionally strong vacuum and a long, wide hose. Most people vacuum the loose insulation straight into long garbage bags made specifically to hold old insulation and to work with vacuum systems.
The video posted here shows how one homeowner handled an old insulation removal project on his own. He used rental equipment to get the job done for the best possible price. After all, most homeowners only need to remove old insulation once. He rented a vacuum from a local equipment rental service and purchased insulation bags online. In the end, he was able to clear out all of the insulation so he could air seal the space. The new insulation should help reduce his energy bills and carbon footprint.
