A Valley With Real Seasons
Spray Foam Insulation in Moraga deals with a valley that has real seasons by Bay Area standards. Records from Saint Mary's College show an average year with 27.47 inches of rain, 40 nights at or below 32 degrees and 26 days at or above 90. That range means insulation matters for both winter comfort and summer cooling.
Winter nights
Forty frosty nights a year make cold floors and drafty walls noticeable. Floor insulation over crawl spaces, attic sealing and wall fill all help.
Summer days
Hot days push heat through thin attics into the rooms below. Sealing and depth in the attic, and foam in bonus rooms and vaulted ceilings, keep upper floors cooler.
Owners
Moraga incorporated on November 13, 1974, uniting Moraga Town, Rheem and Rheem Valley. The 2020 census counted 5,932 housing units, 81.2% owner-occupied.
Zone
Moraga is in Contra Costa County. ENERGY STAR recommends R-49 for an uninsulated zone 3 attic and R-19 under floors.
Moisture
With more rain than the bayside cities, we check roofs and crawl spaces for leaks before insulating.
Townhomes
Moraga has townhome and condo communities as well as single-family homes. In attached homes, we insulate within your unit and work within association rules.
Ducts and the attic
Where ducts or HVAC equipment sit in the attic, they bake on hot days and chill on frosty nights. Sealing duct joints and boots, burying ducts in deep loose fill, or foaming the roof deck are the options, and we price each for your house.
