Insulation that suits San Jose
San Jose summers are warm and dry, so attics bake through the afternoon, and cool winter nights keep the heater running. 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 San Jose, including Willow Glen, the Rose Garden, Cambrian Park and Almaden Valley, after removing what's there and sealing the air leaks around lights, pipes and the attic hatch.
What we see in San Jose homes
- The houses
San Jose's older neighborhoods, like Willow Glen, the Rose Garden and Naglee Park, are full of 1920s to 1940s bungalows and Spanish Revival homes, while most of the city is ranch and tract housing from the 1950s through the 1970s.
- The wildlife
Backyard citrus and fruit trees, ivy and thick hedges all over San Jose give roof rats food and cover right next to the house.
- Under the floor
Many San Jose ranch homes sit on raised foundations, over crawl spaces nobody has looked at since the house was built.

“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…”
“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!”
