Fast, Reliable General Contractor Across Tiburon
Hiring a general contractor in Tiburon means finding someone who actually understands hillside construction, not just someone who can swing a hammer. Iron Beam Contractors regularly works on the steep, narrow lots that define this town, from the bay-facing slopes above Paradise Drive to the ridgeline homes off Lyford Drive. We know the staging challenges, the design review process, and what it takes to get materials up a one-lane road without wasting your budget on logistics. If you’re planning a kitchen remodel, addition, or ADU in Tiburon, call (833) 756-5936 for a free estimate built on real site conditions, not a generic template.
Why Iron Beam Contractors Is Tiburon’s Preferred General Contractor Company
Tiburon homeowners call us because we treat every hillside lot as its own engineering problem. A home on Paradise Drive with a steep approach has different needs than one near Richardson Bay with years of salt-air exposure. We’ve worked both. Nolan Driscoll leads a team that inspects before quoting, so the number we give you reflects what’s actually behind the walls, under the floors, and holding up the roof.
Our reputation in Tiburon comes from one thing: we don’t bury structural surprises in vague allowances. When we open a wall and find rotted framing or outdated wiring, we stop, write a real price, and get your sign-off before touching it. That’s why homeowners across 94920 trust us with kitchens, bathrooms, additions, and full ADU builds. Response to Tiburon is always fast – we schedule site visits around the same one-lane roads and limited turnarounds that would slow down an outside contractor who’s never been here.
We also understand Tiburon’s design review process. Rooflines, window heights, and view corridors all get scrutinized. A small addition can sit for months if the drawings don’t anticipate review board concerns. We plan for that from day one.

Hire a General Contractor in Tiburon
When you hire a General Contractor in Tiburon, you’re hiring someone to run the entire job: permits, materials, trades, inspections, and the daily coordination that keeps a hillside project moving. The job starts with a real site inspection. We look at the foundation type, the access path for equipment, the drainage patterns on the slope, and the condition of what’s hidden. Then we write a contract with line-item pricing, not a round number.
What a typical project costs in Tiburon depends on what you’re doing. A kitchen remodel runs $14,000 – $45,000. A bathroom remodel falls between $9,000 – $28,000. A home addition is $45,000 – $130,000, and an ADU runs $90,000 – $220,000. Window replacement on those large glazed walls facing the bay typically costs $4,500 – $15,000 depending on size and glass spec.
Pre-Construction Inspection
Before any number is final, we inspect. Crawlspaces, framing, wiring, waterproofing, drainage. On Tiburon hillsides, this step matters more than anywhere else because pier-and-beam foundations hide problems that slab-on-grade homes never have.
Written Allowances and Change Orders
We write allowances for the things we can’t see until walls are open. When a surprise appears – rotted header, knob-and-tube wiring, failed waterproofing – we price it in a written change order and get approval before the work continues. Nothing gets buried.
General Contractor Services in Tiburon
General Contractor Services in Tiburon cover the full scope of a remodel or build, from the first demolition cut to the final inspection sign-off. For us, that means interior remodeling, exterior envelope work, hardscape, and ADU installation, all under one contract. You’re not calling a separate roofer, a separate window installer, and a separate concrete crew. One contractor, every phase.
On a Tiburon hillside, that single-point accountability matters more than it does in flat towns. The same project manager who handles your kitchen walls is coordinating the window height with design review, scheduling the concrete pour around the one-lane access, and making sure drainage details hold up under winter rains. The materials come from brands built for coastal conditions: Belgard pavers for patios and walkways, Jerith aluminum fencing that won’t rot in the salt air, and Bufftech vinyl fencing when you need a maintenance-free property line.
Kitchen and Bath Remodeling
These are the projects where wall-opening surprises happen most. We plan for them upfront, specify cabinets and countertops from our brand portfolio, and keep the permit inspection schedule realistic.

Additions and ADUs
From a small bump-out to a full prefab ADU on a steep lot, we handle the geotechnical review, the design review submittal, and the construction logistics. Prefab partnerships with Abodu, Dvele, and Boxabl give Tiburon homeowners options most remodelers can’t offer.

Trusted Brands We Service in Tiburon
Your project deserves a general contractor, not a coordinator. That’s why we stock and install materials from a defined set of manufacturers we know hold up in coastal Marin County. For fencing, we work with Jerith aluminum systems – a good choice within a few hundred feet of salt air where steel rusts fast. Bufftech vinyl fencing gives you a clean property line without staining or rot. For hardscape, Belgard pavers and retaining wall systems handle the drainage demands of a steep Tiburon lot. And ActiveYards fence systems round out the exterior scope when you’re redoing the whole envelope. These are real brands, real standards – specified for longevity, not just curb appeal.

AfterCommon General Contractor Problems We See in Tiburon Homes
- Undersized or rotted framing behind the walls. Pier-and-beam construction with open crawlspaces means decades of marine-layer moisture works its way into joists and headers. We find sagging load-bearing members on a regular basis.
- Outdated wiring that triggers code upgrades. Knob-and-tube and ungrounded circuits are common in older Tiburon homes. Once walls are open, the permit requires bringing those circuits to current code – that’s a real cost, and we price it upfront.
- Failed waterproofing on hillside retaining walls and decks. Winter rains on steep slopes expose poor drainage details quickly. We often rebuild these areas as part of a larger remodel because the failure is structural, not cosmetic.
- Design review stalls on rooflines and window heights. A project that clears every other hurdle can sit for months because the drawings didn’t anticipate view-corridor scrutiny. We submit with that review in mind from the first draft.

FAQs About General Contractor in Tiburon
Because most Tiburon homes sit on pier-and-beam foundations with open crawlspaces, and decades of marine-layer moisture, outdated wiring, and DIY structural changes hide behind the drywall. A slab-on-grade house in flat Corte Madera won’t have rotted joists or knob-and-tube. We plan for this by inspecting first and writing real allowances into the contract, so the climb is a known line item, not a surprise. Call (833) 756-5936 to have us inspect your home before you commit to a number.
It can add months to the schedule if the drawings don’t anticipate the review board’s concerns about rooflines, window heights, and bay view corridors. We submit plans that are already written to those standards, which shortens the wait. For window replacements on large glazed walls, the glass spec and frame profile matter to the review, so we handle that in the submittal. Schedule a free estimate at (833) 756-5936.
Yes. We schedule pours and deliveries around the access, often using conveyors or pumps when a full concrete truck can’t turn around. This is one of the biggest cost and schedule variables on a Tiburon hillside, and it’s one we plan from the first site visit. Call (833) 756-5936 and we’ll walk your access route with you.
A line-item contract with written allowances for hidden conditions, a clear change-order process, the permit and inspection schedule, and the design-review submittal plan. If a contractor won’t put those in writing, the project will drift. We document everything. For a free estimate with a written scope, call (833) 756-5936.
Yes. The open crawlspace means floor framing is exposed to marine-layer moisture and air movement, so subfloor rot is common. We inspect the joists and beams before we set fixtures or level any surface. In a kitchen remodel, that often means adding structural repair to the scope before cabinets go in. Our $14,000 – $45,000 kitchen range includes an allowance for exactly that. Call (833) 756-5936 to schedule an inspection.
