CGI Construction in Marin City, CA | Workshop Contractors
We provide independent CGI construction service across Marin City, handling everything from roof repairs on Marinship-era homes to small kitchen remodels and walk-in shower installations. What makes our CGI work different here is that we’ve spent years solving the problems this specific hillside fog belt creates: rot at flashing points, racking on sloped lots, and staging jobs where a neighbor’s wall sits four feet from your foundation. Call (844) 384-3361 for a free estimate. We know CGI products, and we know Marin City. That combination matters when exterior wood never fully dries and every jobsite tests how well the original 1940s framing was built.
Why Marin City Residents Choose Us for CGI Service
Marin City homes were built fast, for shipyard workers, and they’ve spent seventy-plus years taking on marine-layer moisture. We understand that. Our founder, Noel Figueroa, learned framing from the generation of tradesmen who built working-class neighborhoods by hand, and he’s carried that same eye for square corners and tight flashing into every CGI job we take in the 94965 ZIP. We source CGI components the same way we source everything else: OEM when it makes sense, quality aftermarket when it doesn’t. You get a straight answer either way, because we’re not tied to any manufacturer’s parts program. We’re a general contractor with real experience on CGI Traditions, Signature, Advantage, and Pro Series products, and we treat your house like it has to hold up for another seventy years. Most homeowners don’t realize how many systems interact on a hillside lot. The roof feeds the walls. The walls sit on a deck ledger that’s been damp since 1952. We look at all of it before we touch anything.

Common CGI Construction Problems We Solve in Marin City
- Fog-driven rot at deck and stair connections. Marin City’s marine layer keeps exterior wood damp for months at a stretch, and CGI decking and stair stringers tend to fail first at fastener points where water sits. We replace rotted members and re-flash connections so the repair outlasts the original install.
- Roof sheathing rot around chimney flashing. This is the classic Marinship-era failure. The homes are tight to each other, attics are poorly ventilated, and condensation collects where the chimney penetrates the roof deck. We cut out the damaged sheathing, install OEM-matched replacement, and re-seal the flashing line.
- Racking and joint separation in hillside additions. When a shared retaining wall shifts, everything above it moves. CGI-framed additions pick up racking at wall-to-deck intersections and door openings. We re-square, reinforce, and re-anchor before cosmetic work starts.
- Premature failure of exterior paint and stain on south-facing walls. It sounds backwards, but in Marin City’s fog pocket, the south side gets less direct sun than you’d think, and dampness keeps working the finish. We address the moisture source first, then re-coat with systems that breathe properly.
- Condensation and mold on CGI roof sheathing in tight 1940s attics. Low-slope roofs, minimal eave overhangs, and almost no ridge ventilation. We correct the ventilation, replace affected sheathing, and stop the cycle instead of masking it.
CGI Service in Marin City: What Local Conditions Mean for Your Equipment
Here’s what nobody tells you about doing construction in Marin City: the houses are so close together that we routinely have to negotiate staging access with a neighbor before we even set up a ladder. A roof repair on a steep hillside off Drake Avenue might mean walking materials up a shared stairway, setting a ladder on someone else’s upper driveway for two hours, and coordinating delivery so the truck doesn’t block the only lane in or out. That’s not how it works in Mill Valley or Tiburon or most of southern Marin. Here, it’s the norm. For CGI roof work specifically, this tight access changes how we sequence everything: smaller material drops, hand-carrying bundles, and planning around the neighbor’s schedule. We’ve done it enough that it’s just part of the job, but it’s the single biggest reason you want a contractor who already knows Marin City’s lots. You don’t want someone discovering on day one that the ridge cap delivery can’t make the turn.
Marin City sits in a fog-influenced pocket sheltered by the hills above Sausalito. Marine-layer moisture keeps exterior wood and painted surfaces persistently damp and slow to dry. That drives rot repair, deck and stair replacement, and careful moisture management in walls and crawl spaces more than hot-weather issues. Build it right the first time. The second time costs twice as much and nobody’s happy about it.
CGI Models & Products We Service in Marin City
We work across the full CGI lineup in Marin City: the Traditions Series for classic wood-frame construction, the Signature Series for higher-end finish work, the Advantage Series for mid-range value projects, and the Pro Series for heavier structural applications. Our parts approach is simple: we source OEM CGI parts when they’re available and cost-effective, but we’re not tied to them. For many repairs, high-quality aftermarket components from trusted suppliers offer equal or better performance at a lower cost. You always get an honest repair-versus-replace assessment, weighing the age and condition of the existing CGI system against the cost of new installation. We’re an independent CGI sales & service provider, not a manufacturer affiliate. That independence means we recommend what actually works for a 1950s Marinship-era home on a slope, not what a parts program tells us to push.

FAQs – CGI Construction in Marin City
The fog shortens the life of CGI roof components because persistent marine-layer moisture keeps the sheathing and flashing damp for long stretches, accelerating rot where water settles. In Marin City, the classic failure point is where the chimney penetrates the roof deck, especially on 1940s and 1950s homes with minimal attic ventilation. We address it by replacing rotted sheathing with OEM-matched material, correcting ventilation, and re-sealing every flashing point. Call (844) 384-3361 if your roof has been patched more than once, and we’ll assess what’s actually going on.
Yes, and we do it regularly in Marin City. The original bathrooms in these homes are tight, often five-by-eight feet or smaller, but a walk-in shower with a curbless entry and a linear drain usually fits where a tub once sat. We handle the full scope, from waterproofing the subfloor to setting the pan and finishing the surround. Call (844) 384-3361 for a free measurement and a line-item estimate specific to your bathroom’s footprint.
A small kitchen remodel in Marin City typically runs $9000 to $20000, depending on how much structural work the existing framing needs and whether we’re correcting years of moisture damage behind the cabinets. Many Marinship-era kitchens have water infiltration at the exterior wall that has to be fixed before new cabinets go in. Call (844) 384-3361 and we’ll give you an exact range based on your kitchen’s condition.
We do. Most decks in Marin City are original to the 1940s and 1950s houses, and they carry both the fog-driven rot problem and the hillside settling problem. We inspect the ledger attachment, the post bases, and the connection hardware, then repair or rebuild what’s failed. This is structural work, not just board replacement. When we find rot at a ledger, we pull back enough to see the framing behind it before quoting.
You plan around it. We’ve done enough work in Marin City’s close-set hillside lots to know that staging means negotiating shared access, sometimes using a neighbor’s driveway for a few hours, and scheduling deliveries to keep the lane clear. We coordinate with your neighbors before work starts, and we build that access planning into the schedule from day one. Call (844) 384-3361 and we’ll walk your lot and tell you exactly how we’d stage the job.
