Insulating Chatsworth homes

At the far northwest corner of the Valley, Chatsworth sees big heat in summer and cold nights in winter thanks to the rocky Santa Susana hills. Larger lots and ranch properties also mean garages, workshops and guest houses we can insulate on the same trip.

What we recommend in zone 9

Inland valley attics regularly pass 140°F in summer. We aim for R-38 at minimum and R-49 for homes with ducts in the attic or rooms that overheat, and we often add a radiant barrier. Every Chatsworth job starts with a free inspection: we measure your existing insulation, check for rodents, moisture and wiring issues, and photograph the attic so you can see it for yourself.

The back bedroom used to hit 88 every afternoon in August. After they blew in the new insulation, it stays within a couple of degrees of the living room. My daughter actually sleeps in there now.

They put a radiant barrier on the rafters and topped up the insulation the same day. The upstairs used to feel like an oven at 6pm. Now the AC finally shuts off at night.

We had rats in the attic for years before we bought the house. They vacuumed out all the old stuff, cleaned everything and put fresh insulation in. The smell in the hallway is completely gone.
