Insulating Los Angeles homes

Within the city, we work most in Hollywood, Silver Lake, Los Feliz, Eagle Rock and Mid-City. Many of these homes date from the 1920s–40s and have little or no original insulation, board-sheathed roofs and old wiring. We always inspect wiring before covering it, and we hand-place insulation around anything that needs clearance.

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 Los Angeles 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.

Sample

Our Silver Lake place was drafty and dusty no matter what we did. They sealed a ridiculous number of holes in the attic before insulating. Way less dust, and the heater does not run all night anymore.

We assumed being near the beach meant insulation did not matter. The cottage was freezing every winter. Now it holds heat, and it is a lot quieter with the street noise.

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.
