Insulating Westlake Village homes
Westlake Village homes around the lake were mostly built in the late 1960s and 1970s. Their attics usually have a thin, dusty original layer. Topping up to R-38, and sealing around old recessed lights and attic hatches, makes these homes noticeably quieter and steadier in temperature.
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 Westlake Village 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.

Reviews
What homeowners near Westlake Village say
What people tell us after the first hot afternoon — or the first cold night.
The bonus room over our garage was unusable in summer. They sprayed foam in the ceiling and walls and it is now the most comfortable room in the house.
Friendly, on time and honest. They told us we did not need a radiant barrier and just topped up the insulation. Appreciated not being upsold.
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.
