Fast, Reliable General Contractor Across Tiburon
We’re San Bernardino Contractors, and we’ve spent years working the hillsides, fog belts, and narrow streets that define construction in Tiburon. When a west-facing wall rots out from salt air and winter rain, or a sloped lot starts pushing a retaining wall downhill, you need a General Contractor who’s seen it before. Not someone learning on your dime. Call (855) 473-5620 and we’ll walk the site with you, talk materials that actually survive here, and give you a line-item estimate you can hold us to.
Why San Bernardino Contractors Is Tiburon’s Preferred General Contractor Company
Ruben Castillo built this company around a simple idea: one contractor, every phase of the job. From the roof down to the pavers. That matters more in Tiburon than almost anywhere in Marin, because the site conditions punish coordination gaps. When a hillside delivery can’t reach the lot, someone has to know that before the concrete truck shows up. When a west-facing wall needs stainless fasteners instead of electro-galvanized, the person ordering lumber has to know the difference. Our crews do.
Tiburon homeowners call us because we already know the Town’s design review process, the Marin County permitting path, and which streets off Tiburon Blvd can’t take a full-size material truck. We’ve pulled permits, passed inspections, and re-framed load-bearing walls on split-level ranches built in the 1960s all over Tiburon. When a homeowner off Gilmartin Drive needed a bath rough-in opened up and we found the sill plate rotted through from fog-belt moisture, we didn’t just patch it. We re-framed it with pressure-treated lumber, switched everything to stainless, and resealed before inspection. That’s the standard.

Styles & brands we work with
Remodeling Contractor in Tiburon
A Remodeling Contractor in Tiburon has to think about moisture, slope, and access before anything else. We remodel kitchens, bathrooms, whole homes, and additions throughout 94920, and the first question is always the same: which way does the wall face? West- and north-facing walls in Tiburon stay damp far longer than east-facing ones on the same lot. That changes what we frame with, what fasteners we order, and what waterproofing we spec. A Tiburon kitchen remodel typically runs $14,000 – $45,000, with smaller kitchens landing closer to $9,000 – $20,000. Bathrooms run $9,000 – $28,000, and small baths $5,000 – $12,000.
Whole Home and Room Additions
Tiburon’s housing stock is a mix of mid-century ranches, split-levels, and the occasional teardown-rebuild driven by land values. When we add a room or finish a basement, we’re usually working on slopes that need shoring and drainage planning before framing starts. Home additions in Tiburon run $45,000 – $130,000. A contractor who doesn’t know the Town’s grading and view-corridor rules will get stuck in design review. We don’t.
Kitchens and Baths That Hold Up
A kitchen island in Tiburon runs $3,000 – $10,000, countertops $2,000 – $6,500, and backsplash $800 – $2,500. Bath vanities run $800 – $3,000, walk-in showers $4,500 – $12,000, and tub-to-shower conversions $3,500 – $10,000. We spec cabinets from KraftMaid or Wellborn and plumbing fixtures from Kohler or Grohe when the homeowner wants them. You pick the brand, we handle the build.
Licensed General Contractor in Tiburon
A Licensed General Contractor in Tiburon carries the full scope of the job, not just the pretty parts. We hold the license, pull the permits, and manage every trade from demolition to final inspection. On a hillside lot off the Tiburon Blvd spine, that means coordinating pump trucks when a concrete truck can’t turn around, scheduling inspections around the Town’s review calendar, and making sure the retaining wall is engineered before the excavator cuts into the grade. Roof replacements in Tiburon run $8,000 – $20,000, impact windows $8,000 – $25,000, and paver patios $3,500 – $11,000. You get one accountable team for all of it.
Exterior Systems
Tiburon’s fog belt is hard on roofs, windows, siding, and fencing. We install GAF and CertainTeed roofing systems with hot-dip galvanized or stainless fasteners where the exposure demands it. James Hardie siding, Therma-Tru doors, and PGT impact windows are standard options. Vinyl fencing runs $3,500 – $9,000, aluminum $4,000 – $10,000. Every exterior decision should account for which way the surface faces.
ADUs and Garage Conversions
An ADU in Tiburon runs $90,000 – $220,000, and a garage conversion $30,000 – $80,000. We have access to prefab solutions from Abodu, Dvele, and Plant Prefab for homeowners who want to add square footage without a two-year construction schedule. On a tight hillside lot, a prefab panelized system can mean the difference between a buildable project and a stalled one.
Trusted Brands We Service in Tiburon
You don’t have to take our word on materials. We work with over 50 named brands across every trade category, and you can pick the finish level you want. Want Cambria quartz counters and a Grohe faucet? Done. Want Sterling fixtures and a CertainTeed roof? We’ll spec it and price it. Roofing systems from GAF and CertainTeed, plumbing from Grohe and Sterling, and exterior doors from Therma-Tru are all on our approved list. That means your warranty comes from the manufacturer, not just from us. Call (855) 473-5620 to talk specific product lines for your Tiburon project.

AfterCommon General Contractor Problems We See in Tiburon Homes
- Rotted sill plates and framing in west-facing walls. The fog belt off the bay keeps west and north walls damp for months. Original 1960s galvanized nails and untreated lumber just don’t survive that. We find this constantly, often behind drywall that looks fine from the outside.
- Chalking, pitting window frames and railings. Standard aluminum and vinyl coatings break down fast in salt air. We spec marine-grade or thermally broken aluminum with sealed joints, and we don’t install inland-grade products on west-facing elevations.
- Heaved and undermined pavers on sloped lots. Runoff concentrates on Tiburon’s graded lots and eats the base out from under paver patios and driveways. Sealed joints and proper drainage are the fix, but most installers skip both to save a few hundred dollars.
- Staging failures before the project even starts. Narrow single-lane streets off Tiburon Blvd can’t handle a full-size material truck or concrete mixer. If your contractor hasn’t planned for a pump truck, conveyor, or neighbor-coordinated staging, the job stalls on day one.
Pricing for General Contractor in Tiburon, CA
Here’s what we see in the Tiburon market. These are real numbers from jobs we’ve bid and built:
| Project | Tiburon Market Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Vinyl Fence Installation | $3,500 – $9,000 |
| Paver Patio Installation | $3,500 – $11,000 |
A coastal-spec job costs more than the inland-spec version. Stainless fasteners run three to five times the price of standard electro-galvanized. Marine-grade windows and railings carry a premium. Sealed paver joints take more labor. But the cheap spec fails within a decade in Tiburon’s fog belt, and then you’re paying to tear it out and do it right. We’d rather price it honestly up front. Estimates are free. Call (855) 473-5620 and we’ll give you a written line-item quote.

FAQs About General Contractor in Tiburon
Because the materials and labor are genuinely different. Hot-dip galvanized or stainless fasteners cost three to five times more than standard electro-galvanized nails. Marine-grade aluminum window frames and thermally broken systems carry a manufacturer premium. Fluid-applied waterproofing on west-facing sheathing takes more labor than housewrap alone. A coastal-spec roof on a Tiburon hillside might run $14,000 – $20,000 where an inland version would price out at $8,000 – $12,000. The gap is real, and it’s the difference between a ten-year roof and a twenty-five-year roof. Call (855) 473-5620 for a line-item breakdown on your specific elevation and exposure.
We pre-plan every delivery route before the first truck leaves the yard. Some streets off Tiburon Blvd are single-lane with tight turnarounds, so we coordinate pump trucks for concrete, conveyors for roofing materials, and neighbor-approved staging areas for lumber drops. Occasionally we schedule smaller trucks and more trips. The point is that it’s planned, not improvised on delivery day.
It starts with a site walk and a scope discussion. Then we pull permits through Marin County and the Town of Tiburon, which means design review if the project is visible from the bay or a neighbor’s view corridor. Once permits clear, we schedule the trades in sequence: demo, framing, rough-in, insulation, drywall, finishes, final inspection. Our team manages every step. You get one weekly summary, one point of contact, and a punch list walk at the end.
Yes. Load-bearing wall removal and retaining-wall construction both require engineering, permits, and inspections in Tiburon, and unpermitted work becomes a title and insurance problem when you sell. A licensed GC carries the liability, pulls the permits, and stands behind the work. Ruben Castillo’s team holds the required licenses and pulls permits on every job that requires them.
A full kitchen remodel in Tiburon runs $14,000 – $45,000. A bathroom runs $9,000 – $28,000, and a smaller bath $5,000 – $12,000. Where you land in those ranges depends on square footage, finish level, and whether we uncover moisture damage once walls open up, which we often do on west-facing elevations. Call (855) 473-5620 for an exact quote. Estimates are free.
