Gilroy summers regularly push past 90 degrees, and homes without good air sealing lose the fight before noon. Our spray foam insulation service seals gaps and cracks while simultaneously insulating, which is exactly what older Gilroy tract homes from the 1980s and 1990s need most.
Heat enters Gilroy homes from the top down, especially in the long summer months. Adding or replacing attic insulation is typically the single highest-return improvement a Gilroy homeowner can make, and homes built before 2000 almost always fall short of today's R-value recommendations.
The clay soils common throughout Gilroy shift with the seasons, and that movement pushes ground moisture up into unprotected crawl spaces. Proper crawl space insulation and encapsulation protect wood framing, keep floors warmer in winter, and block the entry points that rodents use near Gilroy's agricultural edges.
During Gilroy's wildfire season, smoke and fine particles enter through the same gaps that drive up energy bills all year. Air sealing before adding insulation is a step many contractors skip — we do not, because it makes everything else work better.
Blown-in insulation reaches corners and irregular spaces that batt insulation cannot fill evenly. For Gilroy homes where original fiberglass batts have settled or compressed over three decades, blown-in coverage restores the thermal performance the house was built to have.
Attics and crawl spaces in Gilroy homes from the 1970s and 1980s sometimes contain older insulation that has degraded, been contaminated by pests, or absorbed moisture over decades of clay-soil movement. Removing old material before installing new insulation is not optional — it is the difference between a job that performs and one that does not.
Gilroy sits at the southern end of Silicon Valley in a valley that traps summer heat. Temperatures regularly climb into the mid-90s from June through September, and the dry air accelerates the breakdown of caulking, weatherstripping, and older insulation materials. Homes built during Gilroy's fast-growth decades of the 1980s and 1990s were constructed to standards that look weak next to what California requires today. That gap between then and now shows up in energy bills every summer and in drafty rooms every winter.
The clay soils under most Gilroy neighborhoods expand when the winter rains arrive and contract sharply in summer drought. That seasonal movement cracks crawl space encapsulation, shifts foundations, and opens new gaps in the building envelope year after year. An insulation contractor who works in Gilroy regularly understands this pattern and builds it into the product and installation method choices — rather than treating every job like it could be anywhere in California.
We pull permits through the City of Gilroy Building Division on any project that requires one, which means the team is familiar with the local inspection process and knows how to prepare jobs for review. That familiarity saves time for homeowners who need permitted work done as part of a remodel or addition.
From homes in the older streets near downtown to the newer subdivisions out toward Glen Loma Ranch and the east side of town, we have worked across the full range of Gilroy housing stock. Gilroy's main corridors — Monterey Road, Tenth Street, and the routes in and out of Christmas Hill Park — are familiar ground. We know that a house on the west side of town can have different soil and drainage conditions than one near the agricultural edges on the east side, and we account for that in every assessment.
Homeowners in Morgan Hill to the north face similar clay-soil and hot-summer conditions. Neighbors in Watsonville to the south deal with their own coastal moisture patterns — we serve both and understand how different each area's needs can be.
Call or submit the contact form and we will respond within 1 business day to set up a time that works for you. No deposit is required to book an assessment.
We inspect your attic, crawl space, or walls in person and give you a written estimate before any work is agreed to. The assessment is free, and the estimate includes the total cost — no surprises after the job starts.
Most attic and crawl space jobs are completed in a single day. For spray foam work, we ask that you, your family, and your pets vacate the home for two to four hours after spraying while the foam cures.
Before we leave, we walk you through the completed work so you can see exactly what was done. If permits are involved, we coordinate the inspection with the City of Gilroy Building Division on your behalf.
We serve all of Gilroy, CA and respond within 1 business day. No deposit to schedule an assessment — just a straight answer on what your home needs and what it costs.
(669) 345-1323Gilroy is a city of roughly 60,000 residents at the southern tip of Silicon Valley, about 30 miles south of San Jose along the US-101 corridor. It is nationally known as the Garlic Capital of the World, with the annual Garlic Festival drawing hundreds of thousands of visitors to Christmas Hill Park each summer. Most of the residential neighborhoods were developed during the 1980s and 1990s, producing a predominantly stucco-exterior, single-family housing stock with tile roofs and two-car garages. Newer subdivisions on the east and south sides — including the Glen Loma Ranch area — represent a more recent wave of growth, with homes ranging from the early 2000s through the 2020s.
The older core around downtown Gilroy contains a smaller stock of Craftsman bungalows and early-20th-century homes that have different insulation and weatherproofing needs than the surrounding tract houses. Homeownership runs around 55 to 60 percent, meaning the majority of residents have a direct stake in their home's maintenance. Nearby Morgan Hill shares much of Gilroy's climate and housing-era profile, while Santa Cruz to the west brings a coastal dimension to the region's insulation needs.
