Attic insulation is one of the most important elements in home improvement if you want to save on your energy bill. When installing the right insulation you can enhance the comfort of your home and improve your home’s acoustics. On this project, we began our work by removing the existing and decompressed blown-in insulation from the attic. We did this by using a 19 HP vacuum and removal tubes. Then we started cleaning the surface areas of the attic. This step allows us to remove any lingering odors in the attic. Then we performed rodent proofing in the attic and exterior of the home This process involved sealing holes and gaps we found to prevent future costly damages to the home. We then moved on to installing R-38 Owen’s Corning blown-in insulation per California building code.
