Fast, Reliable General Contractor Across Millbrae
Hiring a general contractor in Millbrae means finding a team that understands the Peninsula’s seismic and slope realities before the first wall comes down. Seaside Contractors manages full-scope remodels, additions, and ADU construction across Millbrae with one accountable team, so you’re not juggling four subs and a permit office on your own. We know the bay-side drainage issues off El Camino Real and the 1940s ranch footprints that dominate 94030. Call (833) 589-8103 for a free estimate and a straight answer about what your project needs.
Why Seaside Contractors Is Millbrae’s Preferred General Contractor Company
Homeowners in Millbrae bring us in because the scope rarely stops at cosmetic work. A kitchen pull-and-replace on a flat lot in Burlingame can be spec’d in a week. The same project on a Millbrae bay-side street often starts with a geotechnical review, a drainage correction, and a conversation about what a prior owner built without permits. Our team has worked enough of these to fold the unglamorous work into the quote up front, not as a change order discovered mid-demo.
We also carry material partnerships most Millbrae remodelers can’t offer. Need a Cambria countertop spec’d beside a Kohler fixture package and a James Hardie siding detail? One conversation. That breadth matters when you’re planning a $45,000 addition and want the finish selection to match the structural scope. Glen Sorrento, owner at Seaside Contractors, has built the company around that single point of accountability: one contractor, every trade, documented from permit pull to final inspection sign-off.
Styles & brands we work with
Hire a General Contractor in Millbrae
Hire a General Contractor in Millbrae when the project touches structure, systems, or multiple trades and you want one team answerable for the entire sequence. A whole-home remodel on a 1950s stucco ranch off Millbrae Avenue typically runs $14,000 to $45,000 for the kitchen scope alone, with bath remodels starting around $9,000. We manage the permits, the subs, the material deliveries, and the inspection schedule. You get a written line-item quote, a draw schedule tied to milestones, and no mystery change orders.
Remodels and Additions
Millbrae’s housing stock skews toward 1940s – 1960s single-story ranch homes with post-war additions glued on over the decades. When we open a wall, we often find framing that predates current code, flashing that was never installed, or a rear addition that was built without a permit. We correct the hidden work first – Schluter waterproofing in wet areas, proper subfloor framing, drainage at the foundation line – before the finishes go in.
ADU and Garage Conversion Work
ADUs are a growing ask in Millbrae, where lot sizes and zoning allow for detached units that add rental income or multi-generational space. A garage conversion runs $30,000 to $80,000 depending on the existing slab and utility runs. A new ADU through our prefab partners – Abodu, Dvele, Boxabl – lands between $90,000 and $220,000. Either way, the slope and drainage review comes first on bay-side lots.
General Contractor Services in Millbrae
General Contractor Services in Millbrae span kitchen and bath remodels, whole-home renovations, room additions, basement finishing, and deck construction – all under our direct supervision and schedule. We handle the permit package, coordinate the inspections, and bring material pricing through 50+ brand partnerships that a single-trade contractor simply cannot access. A kitchen island installation runs $3,000 to $10,000; a walk-in shower runs $4,500 to $12,000; a full kitchen remodel from studs to countertops lands between $14,000 and $45,000.
Structural and Seismic Scope
On a bay-side street off El Camino Real, we opened up a 1950s ranch remodel and found a rear addition never permitted plus a failing retaining wall feeding water toward the foundation. We pulled the drainage and zoning corrections into the scope of work first, rebuilt the subfloor framing with proper flashing, and scheduled inspection sign-off before hanging any drywall so the whole sequence stayed documented for the homeowner’s records. That is standard practice for us on Millbrae jobs – not a premium add-on.
Finish Selection Without Subcontracting Chaos
Because we are not limited to a single trade, we can price a Toto fixture package, a KraftMaid cabinet line, and a Silestone countertop in the same quote. We’ll match the material to the project – premium where it earns its keep, value-engineered where it doesn’t. The budget stays under your control, and the responsibility stays with one team.

Trusted Brands We Service in Millbrae
Millbrae homeowners want name-brand materials without playing project manager. We install and service American Standard and Toto plumbing fixtures, Schluter waterproofing systems, and Sterling bath products, among dozens of other lines. We can source the parts locally for Millbrae jobs and turn around a broken fixture or a failed waterproofing detail faster than an out-of-town crew. The brands are only as good as the installation behind the wall – and that is the part we do not shortcut.
Common General Contractor Problems We See in Millbrae Homes
- Unpermitted prior additions. Millbrae’s 1940s – 1960s homes were often expanded without permits or inspection sign-off. The work surfaces at resale or insurance claim time, and we have to correct it before the visible remodel can proceed.
- Failing retaining walls on rear slopes. Many bay-side lots step down toward the Millbrae Creek drainage, and the old concrete or timber walls give out. Water follows the failure toward the foundation, which turns a cosmetic remodel into a structural job.
- Drainage and water-table conflicts on steep rear yards. The foggy Peninsula climate keeps soil moisture high year-round. Without a drainage review before the footing goes in, a new addition can trap water against the foundation and rot the framing from day one.
- Cheap-bid change orders on finish materials. A low quote with thin allowances for cabinets and countertops becomes a mid-job upsell when the homeowner actually selects a name-brand line. We write realistic allowances into the quote and let you pick the tier before we start.

FAQs About General Contractor in Millbrae
Yes. Millbrae sits between the Hayward and San Andreas faults, and any structural addition or rebuild triggers seismic load requirements plus the standard California building code wind provisions. The permit office will want engineered calculations for shear walls, hold-downs, and roof-to-wall connections before framing inspection passes. A compliant quote includes that engineering cost; a cheap bid omits it and hopes the inspector doesn’t flag it. Insurers look at the same documentation after a claim. Call (833) 589-8103 and we’ll walk you through what your project actually needs in writing.
Because bay-side lots drain toward the historic Millbrae Creek corridor, and decades of unpermitted rear additions and failing retaining walls have left drainage paths blocked or redirected into foundations. The permit office will not sign off on new construction until the site drainage and prior unpermitted work are addressed. We bundle that cleanup into the opening phase of the project so the visible work is not held hostage later. It is the single biggest difference between a Millbrae quote and a flat-lot Burlingame quote.
A Millbrae-specific quote should include a geotechnical or drainage review on any sloped rear lot, engineered shear wall and seismic tie-down drawings, realistic cabinet and countertop allowances, and a written draw schedule tied to inspection milestones. A cheap bid will show thin allowance numbers, skip the engineering line, and bank on a change order after demo exposes the real condition. Ask for the line items. We provide them. Call (833) 589-8103 for a free written quote.
If a remodel or addition was done without a permit and a later loss occurs – water damage from a failed shower pan, say, or framing damage from a seismic event – the insurer can deny the claim on the basis that the work was never code-inspected. Documented permits and passed inspections are your protection. We pull permits on every structural job in Millbrae and schedule each inspection so the paperwork trail is clean.
Yes. Millbrae’s fog keeps building moisture levels high year-round, so rot repair, proper flashing, and ventilation planning are more aggressive here than in inland climates. We use Schluter waterproofing in every shower and wet area, and we plan deck and fence materials for continuous moisture exposure. Exterior paint and roofing last longer in the mild climate, but the moisture demands more attention behind the wall. That is built into our standard scope, not sold as an upgrade.
