Old insulation does little to almost nothing for your attic. This attic had insulation but it was old and decomposed so it was no longer beneficial to the home. The crew removed all of old insulation, and vacuumed all of the debris up. Once it was clean the crew sanitized with our 100% natural solution, killing all the bacteria. Then they rodent proofed sealing any entry points rodents can be using. Once they completed that step the attic is ready for the insulation. The crew installed R-30 batts insulation for this attic, this attic is now clean and making the home more comfortable.
