Your home should always be comfortable. Did you know your attic is a good way to start. This home had old insulation that was no longer beneficial to the home. As usual we removed old insulation and vacuumed any dust or debris out of the attic. After this they sanitized to kill all and any bacteria. Then they rodent proofed this step is important so rodents do not come in and damage the work. They also sealed all the gaps to prevent air leaks transferring from inside/out the house. Finally the crew installed brand new R-30 batts insulation. This home will now be comfortable through out the year and is up to CA building code.
