Insulation that suits Cupertino

Set against the foothills, Cupertino gets warmer summer afternoons than towns on the Bay shore, so an under-insulated attic shows up in the upstairs rooms. Most of the heat a home gains in summer and loses in winter passes through the attic, so that's where insulation pays off first.

We install Knauf EcoBatt® and blown-in insulation in homes all over Cupertino, including Rancho Rinconada, Monta Vista, Garden Gate and Seven Springs, after removing what's there and sealing the air leaks around lights, pipes and the attic hatch.

Local know-how

What we see in Cupertino homes

  • The houses

    Cupertino's housing is mostly from the 1950s to the 1970s, ranch homes in Rancho Rinconada and Garden Gate and bigger homes toward the foothills in Monta Vista, with many older houses since expanded or rebuilt.

  • The wildlife

    Foothill open space, Stevens Creek and old orchard trees bring rats and mice down into Cupertino neighborhoods.

  • Under the floor

    Older Cupertino homes on raised foundations often have crawl spaces with torn vapor barriers and insulation that has fallen from the floor above.

“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…”

“This company has done a unrivaled job. They stand behind their reputation and are true to their word. They did insulation clean up, installing new insulation, sanitized and rodent proof. It's only been a few days but you can already tell the different in the temperature of our house!”

★★★★★
“Joey and his crew arrived on time. They were very professional and considerate to our needs. We needed our old insulation swapped out and have our attic and crawl space rodent proofed. They did an amazing job at doing so. He was considerate enough to take pictures of all work completed and presented me everything.”
