Serving Gilroy, CA and surrounding areas. (669) 345-1323
Your home was built before insulation standards caught up. We add the coverage it needs now, without tearing out walls, so you stop losing money to Gilroy summers and cold winters.
Retrofit insulation in Gilroy means adding blown-in, spray, or batt material to your existing attic, walls, or crawl space without tearing anything out - most attic jobs finish in one day, and full-home projects typically take two to three days.
Most Gilroy homes built before 1990 were constructed under insulation standards that look very thin compared to what is required today. The result is a house that feels too hot in July, too cold in January, and expensive to condition year-round. Retrofit insulation closes that gap without the disruption of a renovation. It is one of the highest-return upgrades available to homeowners in established Gilroy neighborhoods, and pairing it with commercial insulation is an option for owners of mixed-use or small commercial properties.
The U.S. Department of Energy energy saver guide on insulation explains the performance difference between under-insulated and properly insulated homes in plain terms - it is a useful reference when you are deciding where to start.
If your second-floor rooms or rooms near the roofline are noticeably hotter than the rest of your house during Gilroy's summer heat, under-insulated attic space is the most likely cause. Heat builds in an unprotected attic and radiates down into living areas, making your air conditioner run almost constantly without ever catching up. Comfort problems in summer and winter often trace back to the same root cause.
If your energy bills have gone up steadily but your usage habits have not changed, poor insulation is one of the most common culprits. Heating and cooling systems work harder and longer when conditioned air escapes through thin attic coverage or uninsulated walls. A noticeable spike during Gilroy's hot summers or cool winters is a sign worth investigating before assuming your HVAC system is the problem.
Gilroy neighborhoods built in the 1960s through 1980s were constructed under insulation standards far below what is required today. If your home was built in that era and has never had an insulation upgrade, there is a good chance your attic has a fraction of the material it needs. You can check this yourself by looking into the attic - if the ceiling joists are visible, the insulation level is almost certainly too low.
Drafty rooms and cold floors during Gilroy's cool, wet winters often point to missing or degraded insulation in your crawl space or walls. Moisture from the rainy season can degrade crawl space insulation quickly, and many older homes have little to no wall insulation. These symptoms in winter are worth having a contractor assess before another cold season arrives.
The most common starting point is the attic. That is where the biggest energy losses happen in a typical home, and it is the most accessible area to treat. We blow in material to bring your attic up to current standards, and we seal air leaks around light fixtures and the attic hatch at the same time - because adding insulation without addressing air gaps leaves real savings on the table. For homes where the walls have never been insulated, we use dense-pack techniques to blow material into existing cavities through small drilled holes that are patched after installation. You do not need to remove drywall. Wall insulation as a standalone service is also available if that is where your biggest gap is.
Crawl space work rounds out a full-home retrofit. Under-floor insulation reduces cold floors in winter and addresses the energy losses caused by ground moisture in Gilroy homes with raised foundations. We also handle projects where old, damaged insulation needs to come out before new material goes in - layering over degraded material is not a long-term fix. If your project qualifies for PG&E rebates, the PG&E energy efficiency rebate program can offset a meaningful portion of your cost.
Blown-in or batt material added to bring attic levels up to current standards. Suits most Gilroy homes where attic access is available and energy loss through the ceiling is the primary concern.
Blown-in material injected into existing wall cavities through small drilled holes that are patched after installation. Suits older homes where walls were built with little or no insulation.
Insulation added or replaced beneath floors and along crawl space walls to address cold floors and moisture-related energy loss. Suits homes with raised foundations, common in Gilroy's established neighborhoods.
Attic, walls, and crawl space addressed together as part of a complete upgrade. Suits homeowners in older Gilroy homes who want to bring the entire building envelope up to current standards in one project.
Gilroy sits in a valley that regularly sees summer highs above 95 degrees Fahrenheit and winter nights that drop into the low 30s. Your insulation has to work in both directions - keeping heat out in July and keeping warmth in during January. Homes from the 1960s through 1980s in Gilroy's established neighborhoods were built with a fraction of the coverage those conditions call for. That gap shows up as high PG&E bills, inconsistent room temperatures, and a heating and cooling system that works harder than it should. Gilroy is also served by PG&E's active rebate program, which means a portion of your project cost may come back to you after the work is done.
We work across Gilroy's neighborhoods every week, from the older streets near downtown to the newer subdivisions on the east side of the city. We are also the team homeowners in Morgan Hill and San Jose call when their homes need the same kind of upgrade. The crawl space conditions in this part of Santa Clara County - clay soils, seasonal rain, older vapor barriers - are something we deal with on almost every job.
We ask a few basic questions about your home's age and the issues you have noticed, then schedule a free in-home visit. We reply to all inquiries within 1 business day and come prepared based on what you describe.
We inspect your attic, crawl space, and any walls you are concerned about, checking existing coverage, condition, and where the biggest gaps are. This visit usually takes 30 to 60 minutes, and we share findings before we leave.
You receive a clear written estimate covering materials, scope, and total cost. If a permit is required through the City of Gilroy Building Division, we explain that upfront and handle the application on your behalf.
The crew installs material in the agreed areas, cleans up thoroughly, and shares before-and-after photos of attic and crawl space coverage. We provide all documentation needed for PG&E rebates and federal tax credits.

(669) 345-1323We handle retrofit insulation projects across Gilroy, Morgan Hill, San Jose, Santa Cruz, and 8 other communities in the region. We know the housing stock in each area - including the tract homes and infill development common throughout Gilroy's established neighborhoods.
Insulation slows heat through solid surfaces, but air leaks around fixtures and hatches let conditioned air escape directly. We seal those gaps as part of the installation process. Skipping that step leaves a significant portion of your energy savings unclaimed.
Gilroy falls within PG&E's service territory, and qualifying insulation upgrades can receive rebates that meaningfully reduce your cost. We document the work in the way PG&E requires and help you submit the paperwork - you should not have to figure that process out yourself.
We hold a valid California contractor license and know when Gilroy projects require a permit under the state's energy code. The California Contractors State License Board publishes all license information publicly - we encourage every homeowner to verify before hiring anyone. We handle permits so you never have to.
We combine local knowledge of Gilroy housing stock with the permit expertise and utility rebate familiarity that older-home retrofit projects specifically require. That combination means fewer surprises and a finished project that actually delivers what was promised.
Retrofit-style upgrades for older commercial buildings in Gilroy that need to meet modern energy standards.
