Your walls absorb Gilroy heat all day and release it into your home at night. We add blown-in insulation to existing walls without tearing out drywall so your home stays comfortable year-round.
Wall insulation in Gilroy slows heat from moving through your exterior walls in both directions - most single-story homes take one day to complete. In summer, it stops outdoor heat from pushing into your living spaces. In winter, it holds the warmth you already paid to create inside. Without it, your heating and cooling system works harder than it needs to, and you feel the difference in both comfort and your energy bill.
When insulating walls in a home that is already built, contractors most often use blown-in loose fill. We drill small holes in the wall, feed insulation material through those holes, then patch them before we leave. That means you do not need to tear out drywall to get the job done. Many homeowners combine wall insulation with air sealing services for a more complete thermal envelope improvement.
If your home also has gaps around windows, doors, or in your attic, those leaks can undermine the benefit of adding insulation. Our blown-in insulation approach works in walls, attics, and other cavities where traditional batts are difficult to install.
If your house stays hot well into the evening even after the outdoor temperature drops, your walls are likely absorbing and holding heat all day. This is a common complaint in Gilroy homes during July and August. Properly insulated walls slow that heat transfer dramatically, so your home cools down faster once the sun sets.
If your PG&E bill jumps significantly in June through September beyond what you expect from running the air conditioner, poor wall insulation is a likely contributor. Walls without insulation force your cooling system to work much harder than it should. Comparing your bills year over year can help you spot the pattern.
Stand inside your home on a hot afternoon and press your hand flat against an exterior wall. If it feels noticeably warm - warmer than an interior wall - heat is conducting straight through with little resistance. This simple test works in reverse in winter too: a cold exterior wall on a chilly Gilroy night is a sign heat is escaping.
Homes built in Gilroy before California energy codes took effect were often built with empty wall cavities. If you have never had insulation added and your home is more than 40 years old, there is a strong chance your walls are bare. A contractor can confirm this quickly by drilling a small test hole and probing the cavity.
We install blown-in wall insulation in existing homes using cellulose or fiberglass loose fill. The material is fed through small holes drilled in the wall, then the holes are patched and sanded smooth before we leave. Most projects take one day for a single-story home. If your walls have unusual shapes or gaps that loose fill might not reach, we can also use injected foam. Homeowners who want to address air leaks at the same time often combine this work with air sealing services, which closes gaps before we add insulation.
For homes that also need attic or crawl space work, our blown-in insulation service uses the same approach to fill those cavities. The combination of wall and attic insulation delivers the biggest improvement in comfort and energy savings, especially in Gilroy homes built before 2000.
Made from recycled paper fiber, treated for fire resistance. Cost-effective and works well in most existing walls.
Loose fiberglass fill that settles into wall cavities. Non-combustible and moisture-resistant.
Denser than loose fill, suitable for walls with unusual shapes or gaps that cellulose might not reach as well.
Higher-density fill method that reduces settling over time and provides better air sealing in the wall cavity.
Gilroy sits in the southern Santa Clara Valley and regularly sees summer highs in the 90s, with heat waves pushing past 100 degrees. Walls without adequate insulation absorb that heat all day and release it into your home at night, which means your air conditioner runs longer and your house stays uncomfortable even after the sun goes down. Many of Gilroy older neighborhoods - particularly homes built before the mid-1970s - were constructed before California adopted its current energy efficiency standards. Those homes frequently have little or no insulation in the exterior walls. If your home was built before about 1978, there is a good chance your walls are a significant source of energy loss.
Gilroy mild winters still create enough temperature swing to matter. Nighttime lows regularly drop into the 30s from December through February. Homes without wall insulation lose heat quickly on those cold nights, and residents often notice drafts along exterior walls or rooms that feel noticeably colder than the rest of the house. Homeowners we work with in Morgan Hill and San Jose face similar conditions. According to the U.S. Department of Energy, properly insulating exterior walls can meaningfully reduce heating and cooling costs in climates with seasonal temperature swings like Gilroy.
When you reach out, we will ask about your home - age, square footage, and what is prompting the call. This helps us come prepared with the right equipment. Most Gilroy contractors can schedule an in-home estimate within a few days. We respond within 1 business day.
A technician walks through your home and checks your exterior walls. We may drill a small test hole in an inconspicuous spot to confirm what is currently in the wall cavity. This visit typically takes 30 to 60 minutes, and you will receive a written estimate before any work is scheduled.
The crew drills small holes in your exterior walls and uses a hose to blow insulation material into each wall cavity. We work section by section, checking fill density as we go. For most homes, this part of the job is done in a single day. The work is not particularly loud.
Once the insulation is in place, we patch each hole with a plug and joint compound, then sand the patches smooth. The patches will be ready for paint, but expect to do a touch-up coat yourself. We walk you through what was done and provide documentation for rebates or tax credits.
Most Gilroy homes take one day to complete. We respond within 1 business day and provide written estimates with no pressure.
(669) 345-1323We have worked on Gilroy homes of every age and style, from 1960s tract houses near downtown to newer subdivisions on the east side of town. That local experience means we know what to expect when we drill a test hole in your walls.
You cannot see inside your walls after the job is done, so we use a density gauge to confirm full coverage before we patch the holes. That documentation proves the work was done right, not just done quickly.
We are familiar with PG&E current rebate requirements and can help you understand what you qualify for before you commit. Many Gilroy homeowners are also eligible for the federal tax credit on insulation upgrades.
Our team holds a valid California Contractors State License Board C-2 Insulation and Acoustical Contractor License. You can verify this in seconds on the CSLB website. Licensing matters because it means we carry required insurance and are accountable to a state regulatory body.
We work on Gilroy homes year-round, and we know the neighborhoods, the housing stock, and the climate conditions that make wall insulation a practical investment here.
