Siding Contractor in Gilroy

Pull off a section of old lap siding on a Gilroy home built before the 1990s and the sheathing underneath can tell the real story: streaks of moisture staining, soft spots where fasteners have backed out, sometimes rot that has been sitting hidden for years. This is why GVD Renovations & Remodeling evaluates every Gilroy wall before deciding between a full tear-off and installing over the existing layer. Where the old siding is sound, flat, and dry, siding over it is a legitimate option; where inspection finds damage, GVD removes the old material, repairs the sheathing, and installs a new weather-resistive barrier before any new siding goes up, so the job is done once and done right.

What Siding Replacement Costs in Gilroy and What It Returns at Resale

Cost depends on square footage, material, and how much sheathing repair the tear-off reveals. Fiber cement runs highest per square foot, engineered wood sits in the middle, and insulated vinyl is the most budget-friendly option. Every quote is free and delivered in writing with a fixed total price, so the number you approve is the number you pay.

Resale return favors durable materials. In the 2025 Cost vs. Value Report, fiber cement siding replacement ranks among the top-returning projects nationally at about a 114% cost recoup (roughly $24,420 in added value); vinyl comes in near 97%. On Gilroy's higher-value properties, particularly larger homes in the eastside foothill neighborhoods and newer subdivisions near Gavilan and Christmas Hill, GVD recommends fiber cement. Its 30 to 50 year lifespan and stronger resale return outweigh vinyl's lower upfront cost once a home's value climbs into that bracket, since buyers and appraisers both recognize Hardie board as a premium, low-maintenance exterior.

Choosing Between Fiber Cement, Engineered Wood, and Vinyl for This Market

James Hardie fiber cement carries a Class A fire rating on its own — the most common Class A siding choice GVD installs. It resists warping, rot, hail, and pests, and its factory ColorPlus finish holds color through Gilroy's long, intense summers. It lasts 30 to 50 years, costs the most per square foot, and is the heaviest and slowest material to install. For homes near open grassland, foothill lots, or properties backing up to undeveloped land where fire exposure is a real concern, fiber cement is the recommendation.

LP SmartSide engineered wood gives a real-wood grain look at a lower cost and lighter weight than fiber cement, which speeds installation. It is wax-sealed against moisture and lasts 20 to 30 years.It is combustible on its own, yet LP SmartSide is CAL FIRE-listed for California WUI areas as part of a qualifying fire-rated wall assembly, which GVD can build where required.

Insulated vinyl carries the lowest cost per square foot, making it a fit for tight budgets, rental properties, and homeowners planning a shorter hold period. Like engineered wood, it is combustible and does not provide the same fire resistance as fiber cement.

GVD stocks James Hardie, CertainTeed, Prodigy, and LP product lines and helps homeowners weigh upfront cost against fire exposure, resale value, and how long they plan to stay in the home.

Two Ways to Re-Side: Overlay and Full Tear-Off

Both approaches have their place in Gilroy. Overlay — new siding installed over the existing layer — is a common, legitimate option when the wall underneath is sound, flat, and dry and code and the siding manufacturer's specs allow it. GVD removes the old siding whenever sheathing shows rot, the existing layer is uneven, or code or manufacturer specs require it. Full removal lets the crew inspect framing and sheathing, make any needed repairs, and install a proper weather-resistive barrier before new siding goes on. GVD makes the call during the free estimate, and whichever route fits, installation to manufacturer specifications is what keeps both the workmanship and material warranties solid.

Gilroy's Climate and Fire Code Considerations

Gilroy sits in a valley zone that regularly sees 100°F or higher through summer, which stresses windows, HVAC systems, and exterior finishes alike. The long cooling season adds up in energy bills, and high UV combined with dry heat fades siding color fastest on south- and west-facing walls. Fiber cement's factory-baked ColorPlus finish holds up to this exposure far better than field-painted alternatives.

For homes near wildland-urban interface areas on Gilroy's eastern and southern edges, fire exposure is a real design factor. James Hardie fiber cement carries a Class A fire rating on its own — the most common Class A siding choice GVD installs, and it is the standard recommendation for any property adjacent to open hillside or grassland.

How the Installation Process Works, Start to Finish

Most Gilroy homes are fully re-sided in one to two weeks. A single-story home around 1,500 square feet often finishes in a few days to a week. Two-story homes, multi-color schemes, and jobs requiring sheathing repair take longer, and fiber cement takes more time to cut and hang than vinyl due to its weight and density.

Every proposal includes a start and finish date. GVD crews protect landscaping throughout the project, clean the site daily, and handle any required permits through the City of Gilroy or Santa Clara County depending on the property location, so homeowners never have to navigate permitting themselves.

Warranties and Manufacturer Certification

Every project includes a written workmanship warranty alongside the manufacturer's material warranty. GVD's status as a James Hardie Elite Contractor and LP SmartSide Master Contractor is what keeps those manufacturer material warranties valid in the first place. Many warranties are void if installation doesn't meet manufacturer specifications, which is why certification and proper installation matter as much as the material choice itself.
