This Attic had a lot of debris, and decomposed R-11 insulation. 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 the crew rodent proofed, the prevention of rodents coming in is key to keep the insulation in tact. Therefor the attic was ready for the brand new insulation, the crew installed R-38 batts insulation. The attic is now up to CA code and more comfortable for the family.
