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.

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.

“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.
