EXCELLENT Based on 13 reviews John McLucasJune 6, 2025Trustindex verifies that the original source of the review is Google. I contacted Eduardo after getting 4 estimates from larger insulation companies. I normally only get 3 estimates, but was completely unimpressed by the larger companies I talked to. I have knob and tube wiring in my 75 year old home. We had to come up with a plan to insulate the attic, but keep the batt insulation from the wires (it's a fire danger). We came up with a plan to do this, no other place mentioned the danger. The work was done a couple weeks later, my attic looks amazing!!! Thanks Eduardo!!!! Ximena OlivarMay 22, 2025Trustindex verifies that the original source of the review is Google. These guys were great! Eduardo arrived at our property to review our needs. They provided a fast quote and were very clear about what was included. The job was done in a single day without any issues.

We’re very happy with the work result and the communication! Alejandra Cepeda GilMay 20, 2025Trustindex verifies that the original source of the review is Google. I recently purchased a home in Fremont and this one was built in the 1970s, when I called Reside Homes, Héctor and Eduardo showed up the same day and looked at my attic (we had been hearing weird sounds), they spotted the issues right away and gave me a very affordable quote, they ended up doing clean-up, rodent proofing and insulating my attic in one day, honestly I was super happy with their work I would absolutely recommend them! Ana Isabel SuarezMay 20, 2025Trustindex verifies that the original source of the review is Google. We hired Reside Homes to redo the attic insulation in our property. The team was professional, fast, and very respectful of our space. They explained everything clearly and finished quickly. Juan Manuel Díaz LlanoMay 19, 2025Trustindex verifies that the original source of the review is Google. We reached out to three different companies and Reside was the most cost competitive. What stood out was how professional their proposal and communication were. Even though they were the lowest bid, the service felt premium. The job was completed quickly and without any issues. Highly recommend! neidy alvarez garciaMay 13, 2025Trustindex verifies that the original source of the review is Google. We had Reside Homes come out to deal with our attic — it was a mess from old insulation and there were signs of rodents too. They did the cleanup, new insulation, and rodent proofing all in one go. Honestly wasn’t sure what to expect but they were super professional, got it all done in like a day and a half, and kept everything really clean. They even showed us pictures after. The attic looks way better now and the house feels less drafty already. Would definitely use them again if we ever needed anything similar.

Why Replace Your Attic Insulation?
Learn why old attic insulation loses performance, and how proper removal and replacement by professional attic insulation contractors restores comfort and energy savings in San Jose homes.
Do I need to remove my old insulation before installing new in San Jose?
In many San Jose homes—especially those built before the 1990s—old insulation is either underperforming, contaminated, or improperly installed. If the existing material is compressed, moldy, or has rodent droppings, removal is essential for safety and effectiveness. Installing new insulation on top of old can trap moisture and odors, making things worse. A full removal allows for air sealing, cleanup, and proper installation of high-efficiency materials.
What’s the best insulation type for San Jose’s climate?
For most homes in San Jose, R-38 fiberglass batt insulation is a great balance of cost and performance. It works well for the long, hot summers and cool winter nights typical of the South Bay. For more complex attics or higher energy efficiency goals, blown-in cellulose or even spray foam may be options, but batt insulation remains the most common and Title 24-compliant choice for accessible attics.
How much does attic insulation cost in San Jose?
Costs typically range from $2 to $4 per square foot depending on the condition of your attic, whether removal is needed, and what type of insulation is used. For an average San Jose home with a 1,000–1,200 sq ft attic, expect to spend between $2,500 and $4,500 for full removal, air sealing, and R-38 insulation installation. A free attic inspection will give you a clearer estimate based on your home’s layout and needs.

If you need attic insulation in San Jose, let us show you how easy and affordable it can be. No hidden fees — just better comfort and cleaner air.
Summer Heat Means Higher Bills
San Jose’s hot inland summers often push attic temperatures well above 130°F, especially in older homes with little or no insulation. Without proper thermal protection, heat radiates into living spaces, forcing air conditioners to work harder and raising energy costs. Replacing outdated insulation with modern R-38+ systems can significantly improve comfort and efficiency.
Outdated Insulation in Eichlers and Ranch Homes
Many homes in San Jose—especially Eichlers, ranch-style houses, and mid-century builds—still rely on original or insufficient insulation. These materials often settle, compress, or get contaminated over time. A thorough inspection followed by removal and replacement ensures better airflow and maximum performance year-round.
Air Sealing Makes a Big Difference
Due to decades of patchwork repairs and remodeling, San Jose homes frequently have leaky attics that allow conditioned air to escape. Adding insulation without sealing those leaks misses a huge opportunity. Combining attic insulation with air sealing and proper duct insulation delivers better temperature control and a stronger ROI on your home upgrade.
