Spray Foam Insulation in Santa Rosa, CA

Spray Foam Insulation in Santa Rosa covers an unusually wide range of houses. Wikipedia notes that while the 1906 earthquake leveled most of downtown's commercial buildings, almost all of the city's houses survived, and many still stand in the historic districts around downtown. The city then grew by two-thirds between 1950 and 1970 and by about 3,000 people a year for two decades after that. And since 2017, thousands of homes have been rebuilt after the Tubbs and Glass fires.

Weather that swings

Santa Rosa has a warm-summer Mediterranean climate with 32.20 inches of rain a year, falling on 74 days. It averages 28.9 afternoons at 90°F or more and 30.2 mornings at freezing. The record high, 115°F, came on September 6, 2022. Attics take the summer heat; floors take the winter cold.

Code

Santa Rosa is the representative city for the California Energy Code's Climate Zone 2, the zone that rebuilds, additions and ADUs here are designed to.

What older homes need

In the pre-war cottages and bungalows near downtown, we usually find thin or no attic insulation, nothing under the floor and empty walls. Air sealing and blown-in in the attic, R-19 under the floor and dense-pack walls are the usual plan, with foam where ceilings are vaulted.

Mid-century and later subdivisions

The 1950s-1990s homes in Rincon Valley, Bennett Valley and the west side tend to have some insulation that has settled. Topping up the attic and sealing can lights and top plates usually does the most.

Rebuilds

In Coffey Park, Fountaingrove and Skyhawk, rebuilt homes are insulated to their energy plans before drywall. We work from those plans and schedule around your builder.

Neighborhood by neighborhood

The historic districts around downtown, such as Burbank Gardens, Cherry Street and McDonald Mansion, hold many of the houses that came through 1906. West of Highway 101, older blocks near Railroad Square mix cottages and small bungalows. Northeast, Fountaingrove and Skyhawk are hillside neighborhoods where many homes are now rebuilds. Coffey Park, largely rebuilt after 2017, has newer homes built to current code. Each area gets a different starting point on our quotes.

Owners and rentals

The ACS figures show 56.7% of Santa Rosa's occupied homes are owner-occupied, so a large share of the city is rented. For landlords, attic sealing and blown-in are fast and tenant-friendly: one day of work through the attic hatch, nothing to move out of the living space.

What a visit covers

We check the attic depth and condition, look for leaks at top plates, can lights and the flue, go under the floor to check moisture and insulation, and look at any rooms that run hot or cold. If smoke odor from past fire seasons is still in the attic, we note it. The quote lists each area with its material, R-value and price.
