A Community Rebuilding
Spray Foam Insulation in Larkfield-Wikiup is largely rebuild work. Wikipedia records that the Tubbs Fire destroyed approximately 500 homes in the Larkfield-Wikiup area in October 2017, after blowing in through the Mark West Springs area. Two years later, the 2019 Kincade Fire pushed to the edge of the community during an extreme wind event, and Larkfield was evacuated.
Rebuild insulation
Rebuilt homes are designed to the California Energy Code. We read the plans and energy compliance documents, quote each wall, ceiling and floor to them, and install after rough inspections so the insulation inspection can happen before drywall. Spray foam is an option for vaulted ceilings and tight framing.
Surviving homes
Homes that survived in 2017 or 2019 may still have smoke-tainted insulation in the attic. If so, removal and replacement is an option worth discussing with your insurer.
Housing
Larkfield-Wikiup is unincorporated, with 3,434 housing units in 2020 and 65.3% of occupied homes owner-occupied. The landscape mixes housing developments with vineyards, farms and light industry.
Climate
The area sits at the north edge of Santa Rosa, with the same hot summer afternoons and cold winter mornings. Attics and floors both matter.
What the fires changed
After 2017, much of Larkfield-Wikiup was rebuilt at once, which means many homes here were insulated to the same generation of energy code within a few years of each other. For those homes, the useful work is usually small: sealing gaps that show up as the house settles, adding depth over garages, or insulating a new ADU.
Mark West area
We also cover homes up Mark West Springs Road, where wooded lots and hillside homes take longer to reach and often have crawl spaces under raised floors. Closed-cell foam under the floor and attic sealing are common there.
Smoke-tainted insulation
For homes that came through 2017 or 2019 standing, smoke odor can linger in attic insulation for years. Removing it with a vacuum truck, sealing the attic and blowing in new insulation is usually a one- or two-day job.
