Spray Foam Insulation in Healdsburg, CA

Spray Foam Insulation in Healdsburg faces a hotter summer than Santa Rosa's. Wikipedia's climate data shows July averaging 88.8°F by day and 52.7°F at night, with about 54.6 days a year at 90°F or higher. The record is 117°F, set September 6, 2022. Winter flips it: January averages 57.6°F and 38°F, with about 20 nights at or below freezing. Annual precipitation averages 42.2 inches.

Attics first

With that much summer heat, a poorly insulated attic is the main reason upstairs rooms stay hot into the night. Sealing and adding depth toward R-49 is usually the biggest improvement. Where a home has vaulted ceilings or ducts in the attic, foam on the roof deck is worth considering.

Historic homes

Healdsburg incorporated in 1867. A 1983 cultural resource survey catalogued over 300 historic resources, and the city has two locally designated historic districts, Johnson Street and Matheson. For older homes we plan around original plaster, siding and trim, often dense-packing walls from the outside or working from attics and crawl spaces.

Second homes and rentals

The 2020 census found 10.5% of Healdsburg's 5,051 housing units vacant, which includes seasonal homes. Insulation and sealing help a house hold its temperature between visits.

Fire seasons

The 2019 Kincade Fire forced widespread evacuations including Healdsburg. If your attic took on smoke, we can assess the insulation.

Ducts in the attic

Many Healdsburg homes have their heating and cooling ducts in the attic. On a 100-degree afternoon, those ducts sit in air much hotter than outside, and leaky joints pull attic air into the house. Two approaches work: seal the ducts and bury them in blown-in insulation, or spray foam under the roof deck so the attic stays close to room temperature. We quote both where both apply.

Outside town

We also work in the vineyards and hills around Healdsburg, including Dry Creek and Alexander Valley homes, where long, hot afternoons and older farmhouses make insulation work count.
