Our customer in Upland called us to replace the insulation of their attic. First, our crew provided an attic cleanup by vacuuming out the old R-11 batts and debris. Next, the sanitation services were done to get rid of any bad odors. Then, the crew covered up any entry points in the attic with wire mesh and silicone. Rodent proofing services are important to prevent rodent from entering the attic or crawlspace and cause costly damages. Later, the workers completed the job by installing R-38 batts insulation into the attic.
