Fast, Reliable General Contractor Across Twin Lakes
Seaside Contractors manages full-scope remodels, additions, and ADU construction for homeowners across Twin Lakes, CA. When a wall comes open on a 1930s beach cottage off Seabright Avenue, what’s behind it rarely matches what the plans assumed. That’s the reality of building in this fog belt: rot, undersized framing, outdated wiring, and sandy terrace soils that quietly change the engineering of even modest additions. We price for that reality up front, with written allowances instead of vague promises. That’s why Twin Lakes homeowners call us first when the project is more than a patch job. Call (833) 589-8103 to schedule your free estimate.

Why Seaside Contractors Is Twin Lakes’s Preferred General Contractor Company
We’ve earned our name in Twin Lakes the slow way: by standing behind work on the exact housing stock this neighborhood throws at you. The 1920s fisherman-era bungalows and mid-century ranch remodels around East Cliff Drive and Seabright Avenue were built to different codes, on different assumptions about moisture, long before salt fog was a design consideration. Homeowners on the flats between the harbor and the lagoon know what that means. So do we.
Our response time to Twin Lakes is simple: we’re based in Watsonville, we know the roads, and we schedule Twin Lakes projects as a local route, not a special trip. When a homeowner near Twin Lakes State Beach calls about rot found behind a shower wall, we’re there within days, not weeks. The estimate is free, line-itemed, and written so you can see exactly which number covers what. Glen Sorrento built Seaside Contractors on that transparency, because a contractor who won’t itemize is a contractor planning to surprise you later.
One contractor. Every trade. That’s not a slogan for us, it’s the operating model. When your kitchen remodel in Twin Lakes needs a plumber, electrician, framer, tile setter, and cabinet installer, you don’t coordinate five schedules. We do. And when the permit inspection flags something in the wall cavity, you’re not stuck mediating between subs. You have one accountable team, one contract, and one person who answers the phone.
Styles & brands we work with







Hire a General Contractor in Twin Lakes
Hire a General Contractor in Twin Lakes when the project touches structure, systems, or a permit. That means second-story additions on cottages near Black Point, kitchen and bath remodels throughout 95062, whole-home renovations on the Seabright/Upper Seabright flats, and ADU construction where the lot coverage math requires real engineering. A full home addition in Twin Lakes typically runs $45,000 – $130,000. An ADU runs $90,000 – $220,000. A kitchen remodel runs $14,000 – $45,000. A bathroom remodel runs $9,000 – $28,000. Those are Twin Lakes market ranges, and they move based on what’s behind the walls, what the soil report says, and what coastal code requires.
Our role starts before demolition. We inspect, we scope, we price allowances for the unknowns, and we write it all down. Twin Lakes cottages don’t hide surprises. They hide decades.
Structural and Foundation Work
On the sandy marine-terrace soils between the harbor and the lagoon, even a modest second-story addition often requires deeper footings or pier designs than an inland contractor would spec. We budget for that in the initial estimate, not as a change order later.
Kitchen and Bath Renovation
We manage the full stack: framing repair, rough-in plumbing, waterproofing with Schluter systems, cabinetry, countertops, and finish carpentry. You get one contract, one schedule, and one accountable team from demolition to final walkthrough.
General Contractor Services in Twin Lakes
General Contractor Services in Twin Lakes means something specific here: we’re not just the company that shows up to frame a wall. We own the whole project, from the structural retrofit your 1940s cottage needs before a kitchen island goes in, to the shower pan waterproofing detail that keeps salt air from eating the floor system from underneath. Kitchen remodels in Twin Lakes run $14,000 – $45,000. Bathroom remodels run $9,000 – $28,000. Those numbers assume proper waterproofing, proper ventilation, and proper corrosion-resistant hardware. We don’t quote numbers that assume we’ll skip those.
Our brand access matters here. Schluter for behind-the-wall waterproofing. Toto and American Standard for plumbing fixtures that hold up to coastal moisture. Sterling for tub and shower systems spec’d for small-footprint Twin Lakes bathrooms. When you’re a General Contractor with 50+ vetted brand partnerships, you can match the material to the project instead of forcing one product line into every bid.
Whole Home and Addition Work
When a Twin Lakes homeowner adds a second story to a 1950s ranch near Moran Lake, the permit triggers shear wall upgrades, anchorage retrofits, and ventilation requirements the original build never anticipated. We price those allowances into the contract before demolition starts. Then we build the frame right: pressure-treated sill plates, galvanized hardware, and vapor-managed wall assemblies that can handle daily marine condensation without trapping moisture in the cavity.

ADU and Garage Conversion Build-Outs
Small parcels close to the marsh mean ADUs in Twin Lakes are almost universally build-up rather than build-out. That drives deeper footings and tighter structural engineering. We manage the civil, structural, and finish scopes as one accountable team. Then we spec prefab systems from manufacturers like Abodu or Dvele where the lot and zoning allow, which cuts on-site time dramatically.

Trusted Brands We Service in Twin Lakes
We stock and install parts for the brands Twin Lakes homeowners actually have in their homes. Toto and American Standard fixtures are common in the 1950s – 60s ranch remodels throughout 95062, and we carry the rebuild kits, cartridges, and trim pieces needed to service them. Schluter waterproofing membranes and profiles are a stock item for us, because every tub-to-shower conversion or walk-in shower build near the coast needs them. Sterling tub and shower units spec well for the tight bathroom footprints common in older Twin Lakes cottages. When a part is backordered nationally, our supplier network across 50+ brand partnerships usually finds it faster than a single-brand showroom can.
Common General Contractor Problems We See in Twin Lakes Homes
- Rot in rim joists and sill plates that only surfaces during demolition. Decades of salt-laden marine air work their way into the framing at the exact points where the floor system meets the foundation. Homeowners in the 1920s – 40s cottages between the harbor and Seabright Avenue see this more than almost anyone on the central coast. We find it because we look for it, and we price a framing allowance for it before we open the wall.
- Undersized framing that fails current structural codes. Mid-century remodels in the Upper Seabright flats were often built with 2×4 rafters and minimal shear resistance. Open that wall for an addition, and the permit inspection triggers a shear and anchorage upgrade the original contractor never anticipated. We write that allowance into the contract on day one.
- Sandy terrace soils that change foundation requirements. The marine-terrace substrate under Twin Lakes sits only feet from the marsh and lagoon edges. A footing depth that works in Scotts Valley or the Santa Cruz Mountains may be insufficient here. We spec for the local soil report, not a handbook guess.
- Salt-fog corrosion of hardware and fixtures. Hinges, anchors, and fixture trim rust faster here than almost any other part of Santa Cruz County. We spec stainless or galvanized hardware any time we’re touching a structural connection or exterior-facing component. It costs a few dollars more at rough-in and saves thousands in repair work ten years down the road.
