Fast, Reliable General Contractor Across Half Moon Bay
Hiring a general contractor in Half Moon Bay means finding a team that understands marine fog, salt spray, and the way wind-driven rain finds every weak point in an exterior wall. Seaside Contractors manages the full scope of your project, from the first structural inspection to the final finish, with one accountable team and written pricing. We know the neighborhoods off Highway 1 and the side streets near Main Street, and we schedule work around Coastal Commission review timelines, not against them. Call (833) 589-8103 for a free estimate.

Why Seaside Contractors Is Half Moon Bay’s Preferred General Contractor Company
Half Moon Bay homeowners keep calling us because we do not flinch when a wall opens up and the framing tells a different story than the original quote. Our General Contractor team has worked on coastal cottages near El Granada, bluff-top homes off Miramontes Point Road, and mid-century ranch homes in the 94019 zip code. When a project starts, we know what the permit office expects, what the inspectors enforce, and which materials will actually hold up to the marine air. Glen Sorrento runs every estimate and walks every project, so the person you talk to is the person accountable for the result.
We write allowances for the unknown into every Half Moon Bay contract. That means when a kitchen demo uncovers knob-and-tube wiring or a bathroom subfloor reveals rotted joists, the path forward is already agreed on: we document it, price it, and get your written approval before any additional work begins. You are never funding a surprise with a vague promise. You get a line-item change order and a signed inspection before we move on.
Our response time to Half Moon Bay is same-week for estimates, and we keep crews on the coast consistently enough to have a running knowledge of which inspectors are assigned to which neighborhoods, how the fog affects exterior curing schedules, and when the Coastal Commission meets.
Styles & brands we work with







Construction Company in Half Moon Bay
A construction company in Half Moon Bay is judged by what holds up after five consecutive fog seasons. We build for that standard. Whether the job is a foundation-to-roof structural repair on a 1960s cottage or a high-end addition with engineered lateral resistance, the baseline includes corrosion-rated fasteners, proper flashing, and moisture management behind the wall, not just on the surface.
Structural Work and Coastal Code
Opening up a coastal home in Half Moon Bay often means confronting undersized framing, outdated shear wall construction, or rusted connectors. We bring all of it up to current coastal code, with the permit and inspection history to show for it.
Home Additions and ADUs
A home addition in Half Moon Bay typically runs $45,000 to $130,000. ADU construction from prefab manufacturers like Abodu, Dvele, or Boxabl lands between $90,000 and $220,000 depending on site work, foundation, and utility connections. Coastal Commission review can add months, so we sequence the project to keep momentum while permits clear.
Remodeling Contractor in Half Moon Bay
A remodeling contractor in Half Moon Bay has to plan around what the previous builder hid, not just what the homeowner wants to update. We open walls carefully, inspect before we quote, and price the reality of the house, not a hopeful version of it. Kitchen and bath remodels on the coast consistently reveal failed waterproofing, corroded pipe straps, or wiring that predates code.
Kitchen and Bath Packages
A full kitchen remodel in Half Moon Bay typically runs $14,000 to $45,000, with countertop installation at $2,000 to $6,500 and cabinet installation at $4,000 to $13,000 depending on line and layout. Bathroom remodels land between $9,000 and $28,000, with walk-in showers at $4,500 to $12,000. We spec Schluter waterproofing systems behind tile, because a shower that leaks into coastal framing is a structural problem, not a cosmetic one.
Whole Home Renovation
Whole home remodels on the coast are as much waterproofing and weatherproofing projects as they are aesthetic ones. We tie new work into old, upgrade the building envelope, and keep finish selection moving so the permit clock does not stall the project.

Trusted Brands We Service in Half Moon Bay
We partner with 50+ recognized brands across every trade, so a Half Moon Bay homeowner can choose a Toto toilet or a Delta shower system, and know the spec works. Half Moon Bay projects get the same material access our larger clients do. American Standard and Schluter are the two we lean on most in this climate, because their waterproofing and fixture reliability match the coastal exposure. We keep common replacement parts on hand so a failed valve or cracked pan doesn’t leave a bathroom down for weeks.
Common General Contractor Problems We See in Half Moon Bay Homes
- Rusted fasteners and failed flashing: Salt-laden air eats standard hardware within a few wet seasons. We specify hot-dip galvanized or stainless connectors on every exterior application.
- Outdated wiring and undersized panels: Older cottages and ranch homes in Half Moon Bay often still run on 60-amp service. Once walls open, code requires upgrades, and we write that allowance into the contract upfront.
- Water intrusion at the building envelope: Wind-driven rain on the coast finds gaps that inland homes never expose. We detail rainscreens and flashing as standard, not upgrades, because the fog keeps assemblies wet longer than you’d think.
- Permit timeline gaps: Coastal Commission and local review can stall projects for months. We sequence work so foundation, framing, and finishes move in the right order while the paperwork clears.

FAQs About General Contractor in Half Moon Bay
We write allowances for code-required repairs and structural surprises into the contract before demolition starts. When a wall opens and we find something, we document it with photos, price the repair as a written change order, and get your signature before any additional work begins. A ranch home off Main Street in Half Moon Bay had a bathroom remodel where we opened the subfloor to find rotted joists from decades of wind-driven rain intrusion. Our team sistered the load-bearing members, added a Korolath waterproofing membrane and stainless fasteners, then priced the change order in writing before any tile went down. The homeowner got a dry, code-compliant bath with a signed inspection sign-off, no surprise costs. Call (833) 589-8103 to talk through your project’s allowances.
Half Moon Bay requires building permits for structural work, additions, ADUs, and most remodels that touch plumbing, electrical, or layout. Coastal Commission review applies to projects in the coastal zone, which covers much of the city, and can add 3 to 12 months depending on scope and hearing schedule. We manage the full permit submittal and keep the job sequenced so site work continues where possible while review is pending. Call (833) 589-8103 and we’ll map out your permit path in the first meeting.
Half Moon Bay sits in a foggy, salt-laden coastal zone where construction must be engineered for moisture and marine air. Decay-resistant framing, stainless or hot-dip fasteners, corrosion-rated flashing, and continuous wind-driven-rain detailing are the baseline, not upgrades. The same jobs 20 minutes inland over the hill in San Mateo or Redwood City are built to a completely different durability standard, and a crew that only builds inland will miss details that fail within a few wet seasons here.
Yes. Every kitchen and bath remodel we run in Half Moon Bay is permitted, inspected, and built to coastal code, including waterproofing details that inspectors on the coast actually check. We spec Schluter systems behind every shower and tub surround, because the marine moisture load in Half Moon Bay will expose a shortcut within two or three seasons. A kitchen remodel runs $14,000 to $45,000 and a bathroom $9,000 to $28,000 depending on scope and finishes. Call (833) 589-8103 for a written estimate.
A draw schedule breaks your total project cost into milestone payments that you release as defined phases of work pass inspection. You pay for completed, inspected work, not promises. We tie draws to concrete milestones like foundation sign-off, rough-in approval, and final inspection, and we never ask for a draw before the work that justifies it is complete and documented. It keeps both sides honest and gives you leverage at every stage. Call (833) 589-8103 to see how we structure draws on projects like yours.
