Why Los Altos homes need better insulation

Los Altos' warm summers bake attics in the afternoon, while big trees keep shaded roofs and crawl spaces damp after winter rain. An attic with too little insulation makes the heating and cooling run longer every day of the year.

We insulate homes in the Country Club area, Loyola Corners, North Los Altos and South Los Altos and throughout Los Altos: old material out, air leaks sealed, then new EcoBatt® or blown-in insulation to the right depth.

Local know-how

What we see in Los Altos homes

  • The houses

    Los Altos is mostly larger single-family homes on generous lots, many first built in the 1940s to the 1960s and remodeled or rebuilt since.

  • The wildlife

    Mature oaks, backyard fruit trees and Adobe and Permanente creeks give roof rats and mice plenty of cover in Los Altos.

  • Under the floor

    Raised-foundation homes in Los Altos often hide crawl spaces with old insulation, debris and gaps rodents use.

“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.”

“We went 5+ years without dealing with the insulation in our attic which was basically non-existent and years of old rat feces prior to us moving in. From the start Ron gave us a very competitive estimate. Joy and Sean arrived promptly, went through the job requirements and then through the house recognizing all the vents/ducts that they were going to clean. At the end of the job, they made sure we were completely…”
