This attic had insulation but it was old and decomposed so it was no longer beneficial to the home. The crew started with cleaning the attic using our heavy duty vacuums to remove all the old blown-in insulation. After this they sanitized to kill 99.9% of viruses, odors, and bacteria. Then the crew rodent proofed, the prevention of rodents coming in is key to keep the insulation in tact. Finally the crew installed brand new R-38 blown-in insulation. The home is now energy efficient.
