Our Main Corte Madera Services
Most Corte Madera homeowners reach out for one of three jobs. Each has its own dedicated page with full pricing and local details.
Attic Insulation in Corte Madera
The mid-century ranches and Eichler-style homes scattered through Corte Madera were built with little or no attic insulation by today’s standards. We find original fiberglass batts compressed by decades of moisture, or nothing at all above the ceiling plane. Our crews remove the compromised material, air-seal every penetration, then install fresh Owens Corning or Johns Manville products matched to the roofline. In the Wildland-Urban Interface zones, we specify ignition-resistant assemblies that satisfy local code. Attic Insulation in Corte Madera
Spray Foam Insulation in Corte Madera
Closed-cell spray foam is our go-to recommendation for homes near the Corte Madera Marsh and along the bayside, where crawlspace moisture is chronic and traditional fiberglass fails within seasons. The foam acts as both insulation and vapor barrier, sealing rim joists and subfloor cavities against the damp that rises from saturated soil. We source Icynene and Demilec products for open-cell applications in vented attics, and Rockwool where fire resistance is paramount. Spray Foam Insulation in Corte Madera
Blown In Insulation in Corte Madera
Blown-in insulation, loose fibers pneumatically filled into attic cavities, is the most cost-effective way to bring 1980s and 1990s Corte Madera homes up to current Title 24 standards. We see a lot of settled batts in these vintage builds, and blowing Knauf or GreenFiber cellulose over the top, or stripping and starting fresh, depends on what we find during inspection. The material conforms to irregular joist bays and fills around ductwork and wiring that batts always miss. Blown In Insulation in Corte Madera

Why Corte Madera Homes Are Different
Corte Madera sits in a fog-drenched pocket of Richardson Bay where the marine layer rarely lifts completely, even in July. That persistent dampness, combined with salt-laden air off the water, creates conditions we don’t see in inland Marin cities like San Rafael or Kentfield. Insulation here fails from the outside in: moisture condenses against cool sheathing, mold takes hold in fiberglass cavities, and wood rot spreads through crawlspaces that never fully dry.
The housing stock compounds the challenge. Mid-century ranches and Eichler-style houses, many with flat or low-slope roofs, were built before modern energy codes and often lack any effective thermal boundary. The 1980s and 1990s subdivisions added fiberglass batts that have since settled or been compromised by roof leaks and crawlspace flooding. Newer construction faces California’s stringent Title 24 requirements and, in the Wildland-Urban Interface zones, mandatory wildfire-resistant material specifications that rule out standard products.
Local technicians know that homes backing onto the Corte Madera Marsh suffer chronic crawlspace saturation that inland crews frequently misdiagnose as a simple insulation deficiency. The fix isn’t more fiberglass. It’s vapor barriers, drainage correction, and closed-cell foam on the rim joist. Miss that, and the new insulation fails within two winters.
