Why Sunnyvale homes need better insulation
Sunnyvale lives up to its name: long, warm, dry summers heat attics for months, and that heat works its way into the bedrooms below. An attic with too little insulation makes the heating and cooling run longer every day of the year.
We insulate homes in Cherry Chase, Birdland, Raynor and Lakewood Village and throughout Sunnyvale: old material out, air leaks sealed, then new EcoBatt® or blown-in insulation to the right depth.

What we see in Sunnyvale homes
- The houses
Sunnyvale grew fast in the 1950s and 1960s, so most of its homes are ranch houses and tract homes from that era, including several Eichler neighborhoods, with older bungalows around the Heritage District.
- The wildlife
Fruit trees left from the valley's orchard days, ivy and mature landscaping give roof rats food and shelter in Sunnyvale backyards.
- Under the floor
Many Sunnyvale ranch homes sit on raised foundations, over crawl spaces with their original insulation and a vapor barrier that's long past its best, if there is one at all.

“Attic Crew really saved us! The insulation we had in our house was so ancient, we were using the heater all day and night! After Attic Crew changed our insulation and cleaned our attic, everything became so much better! The house stays cool on the warm days and warm on the cold days.”
“I was looking for a company to do my attic insulation and saw they used Eco bat insulation so I decide to give them a call. Am I glad I did, I never realized what a difference insulation would make! They explained everything to me and made very quick work of the process. I couldn't be happier with the entire experience, from the quote to the final job!”
“First Rate Service. The installation team was 'very' thorough in the removal of our very old blow in insulation. New batts into every nook and cranny. Friendly and left our home a clean site. Well priced. Top job done.”
