Fast, Reliable General Contractor Across Gilroy
Hiring a General Contractor in Gilroy means finding someone who understands that your house sits on ground that moves. A full-scope remodel or addition here is not the same job as it is in Campbell or Los Gatos. West-side ranch houses sit on expansive adobe clay that swells after every wet winter. East-side subdivisions sit on engineered fill that behaves differently. Get the foundation scope wrong at the start and you will burn tens of thousands in change orders before the first cabinet is ordered. We plan for that reality before we ever submit a permit set.
Iron Beam Contractors runs full-scope residential construction across Gilroy, from kitchen and bath remodels to whole-home additions, ADU installations, and exterior envelope work. One contract, one point of contact, one accountable team. Call (833) 756-5936 to schedule a free estimate. We will walk the site, look at the soil, and give you a written, fixed-price scope before you spend a dime.
Why Iron Beam Contractors Is Gilroy’s Preferred General Contractor Company
Gilroy homeowners ask us to manage projects other contractors walk away from. That is because most remodels here are not cosmetic. They are structural. A 1950s ranch off Wren Avenue, a 1970s two-story near Christopher High, a newer custom home in the Glen Loma Ranch area east of Highway 101. Each has a different foundation profile and a different permit path through Gilroy’s building division. We have run all three.
The work we do in Gilroy centers on durable, named materials that hold up to the valley’s hot, dry summers and wet winters. James Hardie siding instead of wood that warps. Schluter waterproofing membranes in every shower. KraftMaid and Wellborn cabinetry specified to the dimensions of older Gilroy homes where nothing is square. Our clients are not looking for the cheapest bid. They are looking for a contractor who will flag the adobe clay before it cracks their new tile.
Every project is led by Nolan Driscoll, our owner and the person you will talk to when you call. Not a rotating project manager. Not a voicemail. Nolan walks every Gilroy job personally before we price it.
Styles & brands we work with







General Contractor Services in Gilroy
General Contractor Services in Gilroy start with a site walk and a hard conversation about what the dirt under your house is going to do to your budget and schedule. A kitchen remodel here runs $14,000 – $45,000. A bathroom runs $9,000 – $28,000. A home addition runs $45,000 – $130,000. An ADU runs $90,000 – $220,000. Those numbers assume we are doing it right: plans, permits, foundation work where required, and materials specified before demo day.
Kitchen and Bath Remodels
We gut and rebuild kitchens and bathrooms across Gilroy, from compact 1950s galley kitchens west of downtown to larger 1990s open-plan kitchens off Santa Teresa Boulevard. Cabinetry is ordered early, not after demolition, because KraftMaid and Wellborn lead times run eight to twelve weeks. Cambria, Silestone, or Caesarstone counters are templated only after cabinets are set, and we do not order slab until the cabinet install date is locked.

Foundations and Structural Work
West-side remodels frequently require piering. We have installed push piers under ranch houses off Welburn Avenue and Miller Avenue where the original shallow footings had shifted. It is not glamorous work, but skipping it is how a $40,000 kitchen becomes a $90,000 disaster. We bring in a licensed geotechnical engineer, get the report, and build the foundation scope into the fixed price before we order a single cabinet.

Construction Company in Gilroy
A Construction Company in Gilroy that only manages subs is a coordinator, not a builder. Iron Beam runs the work directly. We frame, set windows, hang drywall, tile, and install finish carpentry with our own crew. We self-perform the work that sets quality, and we pull permits for every structural, electrical, plumbing, and mechanical scope. Gilroy’s building division reviews plans through Santa Clara County, and hillside-adjacent properties near the eastern foothills trigger additional fire-resistant materials review. We build that into the schedule from day one.
Architect and Designer Coordination
High-end Gilroy projects usually involve an architect, an interior designer, and sometimes a structural engineer. We do not treat them as obstacles. We coordinate directly. Finish schedules get signed before rough-in, not after drywall. When specialty glass or reclaimed wood arrives out of spec, the fix is a conversation, not a change order. Our clients want a builder who speaks the same language as their design team. That is how we run every job.
Long-Lead Material Management
Custom millwork, architectural glass, and European plumbing fixtures can take four to six months to arrive. Order them after demo and you own the delay. We order long-lead items the week the permit is submitted, not the week the walls come down. The price is fixed in writing before we order anything. If a vendor raises a price after the contract is signed, that is our problem, not yours.
Trusted Brands We Service in Gilroy
We specify materials from manufacturers we actually install, not whatever is on sale at the supply yard. Roofing runs through GAF, CertainTeed, Owens Corning, and IKO systems, which matters in Gilroy where summer heat bakes asphalt shingles and winter storms test flashing. For kitchens and baths, we install KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler, Toto, and Grohe fixtures. We keep these brands on our approved ordering list because we have installed them for years and we know how they hold up in this climate. You will not find us substituting unbranded import tile or no-name windows to trim a bid.

AfterCommon General Contractor Problems We See in Gilroy Homes
- West-side foundation movement. Houses off Wren Avenue, Welburn Avenue, and Miller Avenue often sit on shallow footings over adobe clay. After two or three wet winters, slab cracks appear. Any remodel on these lots should start with a geotechnical review, not a sledgehammer.
- East-side engineered fill surprises. Newer subdivisions around Glen Loma Ranch and east of 101 were built on compacted fill, but compaction varies. We have opened walls and found settlement issues the original builder buried. A pre-construction inspection catches these before you commit to a finish schedule.
- Permit delays on hillside-adjacent lots. Properties near the eastern hills trigger fire-resistant building and defensible space requirements through Gilroy’s planning division. That adds two to four weeks to plan review. We file early and push corrections the same week they come back.
- Lead times nobody planned for. Custom cabinetry, specialty tile, and European plumbing fixtures are running three to five months. Homeowners who hire a contractor that orders after demo end up living without a kitchen for an extra season. We order at permit submission.
Pricing for General Contractor in Gilroy, CA
Here is what high-end residential construction actually costs in Gilroy right now. These ranges reflect current material pricing, local permit fees, and the labor market in Santa Clara County’s southern end. They are not lowball bids. They are realistic.
| Project Type | Gilroy Price Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
What moves the number is foundation scope, not paint. A west-side kitchen with piering and seismic upgrade will land at the upper end. An east-side bathroom on a post-1990 slab will land at the lower end. We give you a fixed, written price before ordering materials, and we do not issue change orders unless you change the scope in writing.

FAQs About General Contractor in Gilroy
On the west side of Gilroy, expansive adobe clay means any addition first requires a geotechnical report and often piering before footings can be poured. That adds two to five weeks to the front of the schedule. East-side subdivisions on engineered fill typically skip the piering but may still require compaction testing. We build this time into the schedule before you sign, so the finish date you get is the finish date we hit. Call (833) 756-5936 and we will tell you what your specific lot will require.
An ADU in Gilroy requires building, electrical, plumbing, and mechanical permits through Gilroy’s building division, plus plan review that runs 30 to 90 days depending on whether the property sits in a fire-prone hillside interface. Detached units also need site and setback review. Iron Beam pulls every permit, submits corrections the week they return, and tracks the review through Santa Clara County. A fixed contract with us includes the full permit process.
Yes, and we prefer it. We work directly with your architect and designer from the first site walk, review finish schedules before rough-in, and make sure the structural engineer’s stamp is in the permit set before we cut a single opening. That coordination prevents the biggest costly mistake we see: custom cabinetry or specialty glass arriving out of spec and forcing rework. Call (833) 756-5936 and bring your design team into the first conversation.
Custom cabinetry from KraftMaid and Wellborn runs eight to twelve weeks, and architectural millwork can run longer. We manage lead times by ordering long-lead materials at permit submission, not after demolition. That means your cabinets are already in production while we are still pulling wire. If a vendor slips, Nolan Driscoll calls them personally. We do not let a cabinet delay quietly eat your schedule. We contractually lock the price before ordering, so a vendor price increase before fabrication is our exposure, not yours.
We do not issue a change order unless you ask for something different in writing. If we hit a foundation condition we did not anticipate, that is on us, not a surprise line item. If you decide mid-project to upgrade to a Cambria slab or add a window, we price the change, you approve it in writing, and we adjust the schedule. That is it. Our fixed price is fixed. Call (833) 756-5936 to see the contract language before you commit.
