Insulating Altadena homes
Altadena is rebuilding after the January 2025 Eaton Fire. For rebuilds we insulate attics and walls to current California energy code, and for surviving homes we often remove smoke- and ash-contaminated insulation and install fresh material. Either way, we photograph every stage so you have records for your insurer.
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 Altadena 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 Altadena say
What people tell us after the first hot afternoon — or the first cold night.
I got three quotes. These guys were the only ones who actually went up into the attic and showed me photos before giving me a number. Clean crew, done in a day, and the house is quieter too.
Our 1923 bungalow has an attic you can barely crawl in. They hand-placed the batts around the old framing and were careful about the wiring. Winter mornings are noticeably warmer.
After the fire our attic insulation smelled like smoke for months. They removed it, documented everything for the insurance company, and re-insulated. Professional from start to finish.
