Fast, Reliable General Contractor Across Marin City
Hiring a general contractor in Marin City means finding someone who understands the 1940s hillside bungalows above the commercial strip, the original redwood foundations failing beneath them, and the narrow winding streets that leave almost no room for staging. We get it. San Bernardino Contractors manages whole-home remodels, kitchen and bath work, additions, and ADUs across Marin City with one contract, one schedule, and one accountable team. Call (855) 473-5620 to talk through your project and get a free estimate.
Why San Bernardino Contractors Is Marin City’s Preferred General Contractor Company
Marin City homeowners deal with a specific set of problems. The housing stock dates to the 1940s and 1950s, much of it wood-frame stucco on hillside lots with original foundations that have settled, cracked, or begun to rot in the fog belt just north of the Golden Gate. The cool, moist marine air accelerates dry rot in framing, and heavy winter rains strain older drainage systems. A contractor who has not worked on these homes underestimates what it takes to keep a remodel on track.
Ruben Castillo leads our team with a straight-talking approach to project sequencing. We pull permits before ordering materials. We template cabinetry only after structural work is inspected. That order of operations matters more in Marin City than almost anywhere in Marin County, because lead times on custom millwork and architectural glass set the calendar, not crew speed. Our General Contractor team handles the entire scope, from foundation repair and rough-in to finish carpentry and countertop installation.
We serve all of zip code 94965, including the hillside streets above Donahue Street and the flats near the community center. Homeowners here know that the wrong sequencing on a remodel turns into re-orders, change orders, and a job that stalls halfway through rough-in. We fix that before it starts.
Styles & brands we work with







Hire a General Contractor in Marin City
Hire a General Contractor in Marin City when the project spans more than one trade. A kitchen remodel touches plumbing, electrical, drywall, cabinetry, countertops, flooring, and often structural work if you are opening walls in a 1940s home. Coordinating those trades one at a time is how schedules slip and budgets blow. A single general contractor owns the entire sequence and every material order, which is exactly why homeowners on the hillside choose to work with our Marin City team.
Kitchen remodels in Marin City typically run $14,000 to $45,000 depending on cabinet grade, countertop selection, and whether you are moving plumbing or load-bearing walls. Bathroom remodels land between $9,000 and $28,000. Home additions start around $45,000 and go up to $130,000 when the scope includes foundation work on a sloping lot. You pick the finish level. We build to it.
Designer and Architect Coordination
When a designer specifies Grohe fixtures, Sterling bath hardware, or specialty glass, we receive those specs and write them into a fixed allowance schedule before anything gets ordered. No vague allowances that balloon into change orders later.
Long-Lead Material Sequencing
Custom cabinetry from KraftMaid or Wellborn and quartz slabs from Cambria or Silestone carry real lead times, often six to twelve weeks. We order them after structural and rough-in inspections clear, so the materials arrive exactly when the site is ready, not sitting on a curb with nowhere to stage.
General Contractor Services in Marin City
General Contractor Services in Marin City cover the full span of a residential project: kitchens, bathrooms, whole-home remodels, room additions, deck construction, roofing, windows, siding, fencing, and ADUs. One contractor, every phase. That matters especially in Marin City, where the 1940s homes above the commercial strip often need structural fixes before any finish work can begin. Foundation retrofits, dry rot repair, and seismic upgrades are common first steps on these hillside lots.
Cabinet installation runs $4,000 to $13,000. Countertop installation runs $2,000 to $6,500. A home addition on a sloping Marin City lot starts at $45,000 and reaches $130,000 when it includes retaining walls, deep footings, and hillside drainage. We carry the trade relationships and product access to handle all of it under one contract.
Foundation and Structural Work
Many Marin City homes sit on original redwood foundations that are past their service life. We sequence structural repair first, pull permits, and only then template and order finish materials. That avoids re-ordering custom millwork after settlement shifts dimensions.

Exterior-to-Interior Scope
From GAF or CertainTeed roofing down to Belgard or Unilock pavers, our General Contractor capability covers the outside and the inside of the home. Siding, windows, doors, fencing, and hardscaping are not subcontracted out to a revolving cast of specialists. We manage them directly.

AfterCommon General Contractor Problems We See in Marin City Homes
- Failing original redwood foundations. The 1940s hillside homes above Donahue Street frequently sit on redwood foundation members that have rotted in the fog belt’s damp marine air. We see this on nearly every structural project we take on.
- Narrow street staging limits. The winding streets above the commercial strip leave almost no room for material drops, dumpsters, or equipment. Sequencing deliveries around lead times is the only way to keep a job moving without stacking materials on a neighbor’s property.
- Dry rot in framing and sills. Persistent moisture accelerates rot in the original wood framing. We find it behind stucco, under windows, and at plate lines during most remodels.
- Drainage and settlement on sloping lots. Heavy winter rains strain older drainage systems, and hillside settlement throws floors and door openings out of level. Both affect how we template cabinetry and order architectural glass.

What moves the number most is finish level: builder-grade cabinets land at the low end, custom KraftMaid uppers with Cambria quartz and specialty glass land at the top. Structural work on a hillside lot adds cost, but it is required before finish materials can be ordered. We write the price in a fixed allowance schedule before ordering anything, so the number does not drift after you sign. Call (855) 473-5620 for a free estimate.

FAQs About General Contractor in Marin City
A high-end Marin City kitchen gets scheduled by lead times because custom cabinetry, quartz slabs, and architectural glass are ordered to spec and take six to twelve weeks to arrive. Labor is rarely the bottleneck. We set the calendar around when those materials land, and we sequence structural and rough-in work so the site is ready the day they show up.
We fix the price in writing by building a fixed allowance schedule before any purchase order goes out. Every finish item, from Grohe fixtures to Cambria slabs to KraftMaid cabinet boxes, is assigned a dollar figure you approve. Once approved, that number does not move unless you change the selection. Call (855) 473-5620 for a free estimate.
Yes, if the foundation and load-bearing work is inspected and signed off before finish materials are ordered. We open the relevant areas first, fix what the hillside settlement has done, pull permits, and only then template cabinetry and order glass. That sequence removes the common surprises.
A general contractor receives the designer’s specs, writes them into the allowance schedule, orders every specified brand, and manages all trades to the drawings. We handle the plumbing, electrical, rough-in, cabinetry, countertops, and finish work, and we coordinate with the designer on any field changes before they become change orders.
They affect staging more than cost. The streets above the Marin City commercial strip leave almost no room for material staging, so we time deliveries to arrive in sequence rather than all at once. That scheduling discipline keeps a job moving on streets where a roll-off dumpster on the wrong day blocks the entire block. Call (855) 473-5620 for a free estimate.
