Spray Foam Insulation in El Cerrito, CA

Spray Foam Insulation in El Cerrito covers a city founded by refugees from the 1906 San Francisco earthquake, who settled on what had been Rancho San Pablo. The settlement, first called Rust, incorporated as El Cerrito in August 1917 with about 1,500 residents. The city had 25,962 residents at the 2020 census, and the Hayward Fault runs through it.

Housing

The 2020 census counted 10,996 housing units, 95.3% occupied, with 58.4% of occupied units owner-occupied. Housing ranges from older homes on the flats to hillside houses on steep lots.

Hillside houses

Homes on the hills often have crawl spaces on the downhill side, vaulted ceilings and warm afternoon sun. Floor insulation on the crawl side and attic or roof deck work above usually fix comfort problems.

Older homes

Older houses on the flats need attic sealing, floor insulation and wall fill. We check for knob-and-tube wiring and vermiculite first.

Utilities

PG&E provides gas and electricity in El Cerrito, and the city is a member of MCE for electricity supply. If you are switching to a heat pump, insulation and air sealing first can help a smaller system keep up.

Zone

El Cerrito is in Contra Costa County. ENERGY STAR's zone 3 guidance is R-49 for an uninsulated attic and R-19 under floors.

Vaulted ceilings

Hillside houses often have vaulted or cathedral ceilings with limited rafter depth. Closed-cell foam gives the most R-value per inch where we can reach the cavities, often during a reroof or remodel.
