Fast, Reliable General Contractor Across Millbrae
Hiring a General Contractor in Millbrae means finding someone who understands this city’s particular building department, its aging housing stock, and the seismic reality of living directly on the San Andreas Fault. We’re Iron Beam Contractors, and we manage full-scope residential projects across Millbrae from kitchen remodels to whole-home additions, ADU installations, and exterior renovations. If you’re planning a significant project here, call us at (833) 756-5936. We’ll walk you through what your job will actually cost, what the permit timeline looks like, and where the real schedule risks sit.
Millbrae is a tight grid of mid-century ranchers, steep hillside custom homes in the Highlands, and newer transit-adjacent infill near the BART/Caltrain station. Each of those building types has different structural realities, different permit triggers, and different material requirements. That’s why this page isn’t a generic contractor pitch. It’s a field-level briefing on construction in Millbrae specifically: what costs look like, what the city’s plan check culture does to your timeline, and how a contractor who knows the local process can keep your project moving.
Why Iron Beam Contractors Is Millbrae’s Preferred General Contractor Company
Millbrae homeowners call us because we run projects with a structural engineer’s discipline and a tradesperson’s bluntness. Led by Nolan Driscoll, our team coordinates every trade under one contract: framing, plumbing, electrical, millwork, stone, roofing, hardscape, and ADU installation. No parade of disconnected subs. One accountable team. That’s the difference between a project that drifts and a project that closes out.
We know Millbrae’s building department by its counter hours, not by reputation. We’ve pulled permits for hillside work in the Highlands, for kitchen remodels on flat lots off El Camino Real, and for ADU installations near the station. We know that a simple plan check can clear in a week, but anything touching the hillside overlay or the downtown precise plan can sit for months if you submit at the wrong time. That local knowledge keeps schedules realistic and budgets from blowing out on storage fees and idle crews.
Our reputation in Millbrae is built on written line-item quotes, fixed pricing with no change orders unless you sign them, and material selections locked before long-lead orders go out. We don’t ask you to trust a handshake. We ask you to read the allowance schedule.
Styles & brands we work with
General Contractor Services in Millbrae
General Contractor Services in Millbrae span the jobs where multiple trades have to sequence correctly on a single site: full kitchen remodels, primary bath rebuilds, room additions, and whole-home renovations. A Millbrae homeowner typically needs this level of coordination when the project touches structural elements, plumbing, electrical, and finishes at the same time. In Millbrae, kitchen remodels run roughly $14,000 – $45,000, bathroom remodels $9,000 – $28,000, and a room addition $45,000 – $130,000 depending on foundation work, seismic upgrades, and finish tier.
Kitchen and Bath Remodels
Millbrae’s mid-century ranchers often still have original 1940s and 1960s redwood framing. That’s good material, but it moves differently than modern dimensional lumber, and we plan rough-in around it. We spec cabinetry through KraftMaid, countertops through Cambria and Silestone, and fixtures through Kohler, Moen, and Grohe. Selections go into the contract before we order.
Whole-Home and Interior Coordination
A whole-home remodel in Millbrae usually means working around the homeowner’s existing footprint while the city reviews plans. We handle the permit set, structural drawings, and trade sequencing so you’re not managing dead air between demo and rough-in. Every phase gets a written scope, so change orders stay deliberate, not accidental.

Construction Company in Millbrae
As the Construction Company Millbrae homeowners use when the job is too complex for a single-trade specialist, Iron Beam handles exterior and structural work alongside interior finishes. We replace roofs with GAF and CertainTeed systems, install James Hardie siding, pour driveways, build paver patios with Belgard and Unilock product, and frame ADU additions from foundation to occupancy. A roof replacement in Millbrae runs $8,000 – $20,000. An ADU construction project runs $90,000 – $220,000. A concrete driveway runs $4,500 – $12,000.
Exterior Systems and Hardscape
Salt-laden air from the bay moves through Millbrae year-round. We see it corrode flashing, fasteners, and low-grade metals faster than homeowners expect. That’s why we spec stainless or coated fasteners on exterior work and use GAF and CertainTeed roofing systems with proper venting. It’s not about selling better products. It’s about not redoing the work in year six.
ADU and Prefab Installation
Millbrae’s zoning near the BART station has pushed more homeowners toward ADUs. We have partnerships with Abodu, Dvele, Mighty Buildings, Boxabl, and Plant Prefab, which means we can manage prefab delivery, crane placement if needed, foundation systems, and utility tie-ins under one contract. Most remodelers can’t carry that scope. We do.
Trusted Brands We Service in Millbrae
We’re authorized to work with 50+ manufacturer brands, and for Millbrae exteriors we lean on GAF and CertainTeed roofing, James Hardie siding, and Owens Corning insulation. What that means for you: we order direct, we handle warranty claims, and we keep the lead times honest. When a Millbrae homeowner asks about a specific roof system or siding profile, we can quote it from a book, not a guess. That’s the difference between a general contractor and a coordinator who’s just passing through a bid.

AfterCommon General Contractor Problems We See in Millbrae Homes
- Hillside overlay permit stalls. Projects on sloped lots in the Millbrae Highlands or near the downtown precise plan can sit in plan check for months. We time submissions around the city’s counter calendar and flag hillside issues before drawings go in.
- Asbestos-laden materials in mid-century builds. Homes from the 1940s – 1960s often have asbestos in flooring, drywall compound, or duct wrap. We budget for testing and abatement as a line item, not a surprise.
- Salt-air corrosion on exterior metals. Millbrae sits on the bay side of the Peninsula. Uncoated flashings and standard fasteners degrade fast. We spec coastal-grade metals from day one.
- Long-lead items killing the schedule. Custom cabinetry, specialty stone, and architectural glass can take 8 – 16 weeks. We place those orders early and lock the price, so the lead time doesn’t become the budget’s problem.

FAQs About General Contractor in Millbrae
The hillside overlay triggers additional geotechnical and design review that can add two to six months to your permit timeline, depending on slope and lot coverage. We submit hillside projects early and with complete soils reports, which keeps the plan check queue from stalling on incomplete paperwork. Call (833) 756-5936 before you sketch a hillside addition, or it’ll cost you a season.
Custom cabinetry, stone countertops, and architectural glass are the long pole. KraftMaid custom lines run 6 – 10 weeks. Cambria and Silestone slabs are usually in stock, but fabrication slots fill fast. We place those orders within the first two weeks of your project so the material arrives when the rough-in passes, not six weeks later. Call us at (833) 756-5936 and we’ll walk you through the current lead times from our vendor network.
Every change order is written, priced, and signed before any work changes. If you upgrade your fixture package or add a structural detail, we update the allowance schedule and the contract in writing. That protects you from a designer’s selection that exceeds your allowance and us from an open-ended scope. No verbal handshakes on money.
Millbrae’s building department requires permits on structural work, electrical, plumbing, and anything touching the hillside overlay or downtown precise plan. Unpermitted work becomes a liability when you sell, and seismic retrofit work done without inspection won’t hold up with lenders or insurers. We pull permits, schedule inspections, and close them out properly. Call (833) 756-5936 if you’re unsure whether your project needs one.
Millbrae’s persistent coastal fog slows exterior paint curing and concrete drying, especially between November and March when rain interrupts schedules. We plan exterior paint and stucco work for the drier months and use mix designs that tolerate cooler, damp curing conditions. Salt-laden air also accelerates corrosion, so we spec stainless or coated fasteners and flashings on all exterior assemblies.
