Why Larkfield-Wikiup Homes Are Different
Larkfield-Wikiup sits just north of Santa Rosa along the Old Redwood Highway corridor, where the housing stock runs from 1960s ranch homes to 1990s two-story builds. What we see in attics here is consistent: original fiberglass batts that have settled to half their rated R-value, or blown-in material that’s been trampled flat by decades of contractors running wire and ductwork. The Mark West Creek drainage means a good number of homes in the lower-lying streets off Larkfield Center Drive deal with elevated crawlspace moisture, which pushes humidity into the attic and degrades insulation performance faster than a dry, open attic. We also work in the Wikiup area east of 101, where homes tend to be newer but often under-insulated at the ceiling for what the afternoon sun does to a roofline in July. Air sealing matters here as much as the insulation itself. A home only performs as well as its ceiling plane, and in Larkfield-Wikiup the ceiling plane is where the temperature difference is sharpest.
Our Main Larkfield-Wikiup Services
Most Larkfield-Wikiup homeowners call us about one of two situations: an attic that’s under-insulated for the climate, or an attic that needs old material pulled out before new material goes in. Here’s what each job involves locally.
Attic Insulation in Larkfield-Wikiup
Attic insulation work in Larkfield-Wikiup usually starts with checking what’s already there: how many inches, what R-value it’s performing at, and whether vents are blocked. Older homes in the Larkfield side of town often have R-19 or less at the ceiling, and bringing that up to R-38 or R-49 makes an immediate difference in how long the house holds temperature. We install batts and rolls from Owens Corning, Johns Manville, and Knauf, and we air seal before insulating so the new material actually does its job. Full details are on the Attic Insulation in Larkfield-Wikiup page.
Blown In Insulation in Larkfield-Wikiup
Blown-in insulation is the most common solution for Larkfield-Wikiup attics with irregular joist spacing, low-clearance corners, or existing batts that just need a top-up layer. We blow loose-fill fiberglass or cellulose across the attic floor to a set depth, which gets you to a measurable R-value without tearing anything out. It’s fast, it fills tight spots, and it works well in the 1960s-1980s attic layouts we see throughout the neighborhood. Material comes from Owens Corning and GreenFiber. See Blown In Insulation in Larkfield-Wikiup for specifics.
Insulation Removal in Larkfield-Wikiup
Removal makes sense in Larkfield-Wikiup when the existing material is rodent-soiled, water-damaged from a roof leak, or so old it’s doing almost nothing. We vacuum out the old insulation, bag it, and leave the attic clean before anything new goes in. Homes near Mark West Creek that have had moisture problems are the usual candidates. We remove fiberglass, cellulose, and old rock wool, and the attic is ready for air sealing and fresh insulation the same day. Read Insulation Removal in Larkfield-Wikiup for what the process covers.

For straightforward insulation installation or removal in an existing home, no permit is required in unincorporated Sonoma County, which covers the Larkfield-Wikiup area. If your project involves structural changes or new construction, the contractor or homeowner pulls that permit. We’ll tell you upfront if your job needs one.
For our climate zone, the Department of Energy recommends R-38 to R-49 at the ceiling. Most Larkfield-Wikiup homes we inspect are sitting at R-19 or below, which means they’re losing heat all winter and fighting attic heat all summer. Closing that gap is the single most effective insulation upgrade most homes here can get.
