CGI Construction in Marin City, CA | Seaside Contractors
We provide independent CGI sales and service across Marin City, handling everything from kitchen cabinet installation to standing seam metal roofing. What sets our CGI work here apart is that we build around Marin City’s unincorporated Marin County permitting process and the fog-driven moisture that eats into poorly installed products. If you’re weighing a small kitchen remodel, a tub-to-shower conversion, or a metal roof off Cole Drive, call (833) 589-8103 for a free estimate.
Seaside Contractors is not a single-trade shop. We’re a licensed general contractor with 50+ brand partnerships across cabinetry, countertops, roofing, windows, and more. For Marin City homeowners, that means one accountable team from CGI sales & service through final inspection, with no gaps between trades.
Why Marin City Residents Choose Us for CGI Service
CGI products show up in a lot of the remodels we walk into around Marin City, and we’ve learned their quirks the hard way. Particleboard cabinet boxes, quartz countertop edges, metal roof fasteners, vanity finishes. We know which failures are common here and which are install errors from previous contractors. That matters in a place where the fog comes in off the Headlands and settles into unventilated kitchens.
Glen Sorrento, our owner, grew up watching lagoon-side homes in Foster City get built and rebuilt, then spent two-plus decades working through every project type the Peninsula throws at a contractor. He treats a CGI spec sheet the same way he treats a GAF roofing system: something to be read carefully, not skimmed, a habit sharpened by years of CGI repair in Belvedere. When we quote CGI work in Marin City, we quote it based on what this fog-cooled coastal pocket will actually do to the product over ten years, not just what fits the budget today.

Common CGI Construction Problems We Solve in Marin City
- Swollen, delaminating particleboard cabinet boxes. The 1940s originals and mid-century bungalows in Marin City often lack proper range hoods or exhaust fans. Years of coastal humidity and winter rain drive moisture into the cabinet carcass. We see the telltale swelling along the bottom edges of CGI ready-to-assemble boxes. Repair means drying out the affected area, addressing ventilation, and replacing boxes where the particleboard has lost structural integrity.
- Chips and cracks at quartz countertop sink cutouts. Hillside homes off Donahue Street and Cole Drive settle over decades. When the floor’s out of level and the cabinets underneath weren’t shimmed properly, the stress concentrates at the sink cutout and the front edge. CGI quartz countertops are durable, but they don’t forgive a sloppy substrate. We pull the countertop, level the base, and re-set it correctly.
- Fastener back-out on standing seam metal roofs. Steep, fog-exposed roofs in Marin City cycle through wet and dry constantly. CGI metal roof panels expand and contract with temperature shifts, and fasteners that were over-torqued at install back out within a few seasons. Sealant at penetrations fails next. The leak then tracks along framing on narrow lots where water has nowhere good to go.
- Peeling finishes and joint separation on all-wood bath vanities. CGI’s all-wood vanity line holds up fine when bathrooms have proper ventilation and moisture barriers. In a 1940s original with a single small window and no exhaust fan, the joints open up and the finish starts peeling within a few years. We replace the damaged vanity and fix the underlying moisture issue so it doesn’t happen again.
- Improperly flashed penetrations on metal roofing. Chimneys, plumbing vents, and skylights are where most CGI metal roof leaks start in Marin City. If the flashing detail wasn’t bent and sealed correctly for the specific panel profile, water finds a path. We re-detail the penetration with the right flashing and a sealant rated for constant coastal damp.
CGI Service in Marin City: What Local Conditions Mean for Your Equipment
Because Marin City is unincorporated, every permit runs through Marin County rather than a local building department. Hillside lots off Cole Drive and Donahue Street routinely need geotechnical review and drainage plans before approval, which adds weeks to any CGI cabinet or roofing project. A homeowner in a neighboring incorporated city files at city hall and moves on. Here, the county engineer may want to understand the soil stability and runoff before signing off on a kitchen remodel that touches structural walls or a metal roof that changes the roof load.
We plan for that timeline from the first site visit. When a client on Cole Drive wants CGI cabinets and quartz countertops, we start the county paperwork early and build the geotech review into the project schedule. It’s slower, but it’s predictable if you know the process. We do.
CGI Models & Products We Service in Marin City
We work on the full CGI residential range: Ready-to-Assemble Kitchen Cabinets, All-Wood Bath Vanities, Quartz Countertops, and Standing Seam Metal Roofing. For critical components like cabinet hinges and roof fasteners, we use OEM CGI parts to preserve warranty and fit. For generic items, shelf pins, sealants, we source quality aftermarket equivalents that keep the quote reasonable without cutting corners.
Our local familiarity with Marin City’s housing stock—plus our Tiburon CGI service—means we carry common CGI components and know which supply runs are quick and which aren’t. When you call about a failed hinge or a lifted roof panel, we can generally diagnose it over the phone and come prepared.

AfterCGI Service Pricing in Marin City
Pricing varies by scope, access, and what we find underneath. A small kitchen remodel in a 1940s original on a tight hillside lot costs more per square foot than the same remodel in a flat infill house, because the access is harder and the substrate usually needs more prep. Here’s where the common CGI jobs land:
| Service | Typical Range |
|---|---|
| Small Kitchen Remodel | $9,000 – $20,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Cabinet Installation | $4,000 – $13,000 |
Every estimate includes a written line-item breakdown, and the price we quote is the price you pay unless we uncover something structural that needs your sign-off. Call (833) 589-8103 to schedule a free estimate, and we’ll walk the site before quoting.

FAQs – CGI Construction in Marin City
Most hillside lots off Cole Drive and Donahue Street require geotechnical review and a drainage plan as part of the Marin County permit process. It depends on the slope and the scope of the structural work. We include the geotech requirement in our initial assessment, so there’s no surprise three weeks into the permit review. Call (833) 589-8103 and we’ll let you know what your specific lot will trigger.
The persistent fog and winter rain drive moisture into kitchens that lack proper ventilation, especially in the 1940s originals. CGI’s ready-to-assemble cabinets use particleboard boxes, which swell and delaminate when that moisture gets trapped. The cabinet itself is rarely the problem, it’s the environment. We fix the ventilation issue and replace only the damaged components.
Yes. Tub-to-shower conversions are one of the most useful upgrades for Marin City’s older bathrooms, and CGI products work well when the moisture barrier and waterproofing are done right underneath. In a 1940s original with minimal ventilation, the waterproofing detail matters more than the brand of the finish. We spec the CGI line where it fits, and our experience with CGI in Chinatown helps us build the substrate to handle the coastal damp.
Plan on four to eight weeks for Marin County permitting, longer if the lot is on a steep hillside requiring geotechnical review. The county reviews drainage, roof load, and access before approval. We manage the entire permit package and stay on top of the county’s review schedule. Call (833) 589-8103 for a realistic timeline on your property.
Yes, when the existing cabinet boxes are structurally sound. Refacing solid wood fronts and replacing hardware costs considerably less than new boxes. But if the particleboard has absorbed moisture and lost its integrity, refacing just puts a bandage on a failing structure. We’ll tell you which one we’d do in our own house. Estimates are free at (833) 589-8103.
