Spray Foam Insulation in Orinda, CA

Spray Foam Insulation in Orinda does more work than in the flatlands. Over the Berkeley Hills, the climate swings wider: Orinda's record high is 110 degrees and its record low 15, according to Wikipedia, and it averages 30.53 inches of precipitation a year, wetter than the bayside cities. Hot summer afternoons and cold winter nights both test an under-insulated house.

Hillside houses

Many Orinda homes sit on slopes, with crawl spaces on the downhill side, vaulted ceilings and large windows. Attic sealing and depth, floor insulation over crawl spaces, and closed-cell foam in vaulted ceilings during remodels are common work.

Owners

In 2020 Orinda had 7,232 housing units, and 88.1% of occupied units were owner-occupied. Owners tend to plan long-term improvements and often phase work.

Private roads

Residents noted at a 2018 council meeting that Orinda has 29 miles of private roads. We plan access for steep and narrow driveways when we schedule.

Moisture

With more rain than the bayside cities, we check roofs and crawl spaces for leaks and damp framing before insulating.

Zone

Orinda is in Contra Costa County. For existing attics, ENERGY STAR's zone 3 guidance is R-49 when empty and adding R-38 over three to four inches.

Ducts and equipment in the attic

Where the furnace, air conditioner or ducts sit in the attic, they spend summer in the hottest part of the house and winter in the coldest. Sealing duct joints and boots, burying ducts in deep loose fill, or spraying foam under the roof deck are the options. We explain the cost and benefit of each for your house.
