Craftsman bungalows, Spanish revivals and hillside homes under the San Gabriels. These are older houses with tight attics, and they reward careful hand work over a quick hose job.
Explore Burbank, Glendale & PasadenaFrom Hollywood bungalows to Santa Monica cottages, the problem here is less raw heat and more old houses that leak air in every direction. We seal first, then insulate.
Explore Los Angeles & the WestsideBig two-story homes, ducts in the attic and serious heat. North of the Newhall Pass, insulation and radiant barrier are less of a nice-to-have and more how you make the upstairs livable.
Explore Santa Clarita & Antelope ValleyJust over the hill from the Valley: Calabasas, Agoura Hills, Thousand Oaks and Simi Valley. Newer homes, bigger attics and plenty of summer heat behind the coastal hills.

Three flattened inches, or sixteen fresh ones
Most attics we open look like the “before”: a thin, gray layer from decades ago, crushed by storage and torn up by every cable and AC install since. Drag the slider to see the same kind of attic after air sealing and a full blown-in layer.
We photograph every attic before and after, so you see exactly what you paid for, even though you will never go up there.

Year-round comfort
One upgrade, two seasons
The insulation that keeps 140°F attic heat out of your bedrooms in August is the same insulation that keeps your heater’s warmth in on a 40-degree January night in the Valley.
- Even temperatures from room to room
- An AC and furnace that run less
- Less dust, fewer drafts, quieter rooms

Reviews
Comfortable homes, happy homeowners
What people tell us after the first hot afternoon — or the first cold night.
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.
