Fast, Reliable General Contractor Across Los Gatos
Hiring a general contractor in Los Gatos means finding a team that understands hillside engineering, WUI fire code, and century-old housing stock in the same breath. Seaside Contractors handles the scope no single-trade contractor can: structural work, roofing, windows, kitchens, baths, and ADUs, under one accountable roof. Glen Sorrento leads our team with a build-it-right-behind-the-wall standard, and we’re a direct call away at (833) 589-8103. Whether you’re off Summit Road in 95033 or near the Boulevard in 95030, we’ll give you a straight answer and a written line-item quote.

Why Seaside Contractors Is Los Gatos’s Preferred General Contractor Company
Los Gatos homeowners keep our number because we don’t make flatland assumptions on hillside lots. The town’s Wildland-Urban Interface zone runs right through the 95033 corridor and parts of 95030 toward Monte Sereno, and that changes what a compliant quote actually includes. We’ve rebuilt decks where the original ledger pulled away from the rim joist after an atmospheric-river storm, and we know what the Town plan checker will flag before the inspector ever sees it. That saves you change orders and keeps your permit moving.
We also work the housing stock other remodelers avoid. Century-old Victorians and Craftsman bungalows near the downtown core carry knob-and-tube wiring, undersized footings, and load paths that were never engineered for a second-story addition. A mid-century ranch in 95032 is a different job entirely, usually cleaner structure, but often with failing lateral bracing and single-pane windows. We’ll match the material to the project, and we’ll tell you when a value-engineered line makes sense and when it doesn’t.
Our brand partnerships span GAF, CertainTeed, Owens Corning, KraftMaid, Cambria, Schluter, Toto, James Hardie, PGT, Therma-Tru, Belgard, Abodu, and Dvele, to name a few. That breadth matters in Los Gatos specifically because one hillside addition can touch foundation work, Class A roofing, ember-resistant vents, impact windows, and a Schluter waterproofed bathroom, and you don’t want to coordinate five different subs to make that happen. One contractor. Every trade.
Styles & brands we work with







Hire a General Contractor in Los Gatos
Hire a General Contractor in Los Gatos when the project touches more than one trade, carries structural weight, or triggers a permit review that flatland contractors never face. A home addition in the hills, for example, runs $45,000 – $130,000 in this market, and that range reflects what you can’t see in a bid that’s aggressively low: geotechnical soils reports on steep slopes, engineered retaining and drainage, WUI-compliant roof and venting assemblies, and inspection sign-offs the Town actually enforces. We hold the permit, we schedule the inspections, and we hand you the documented compliance file when we’re done.
Hillside Additions and Structural Work
On a Los Gatos hillside lot, a “simple addition” is rarely simple. The Town will frequently require a geotechnical report before foundation design, and sloping grades mean your drainage plan has to handle concentrated winter runoff without sending it into the neighbor’s hillside. We quote that work up front, not as a surprise change order after demolition starts.
Full-Scope Remodels on Any Housing Stock
A kitchen or bath remodel in a 1920s bungalow off the Boulevard often means opening walls and finding undersized joists, original knob-and-tube, and decades of layered DIY fixes. We plan for that, not around it. A $14,000 – $45,000 kitchen in Los Gatos should include the structural correction and waterproofing, not just cabinet boxes and counters.
General Contractor Services in Los Gatos
General Contractor Services in Los Gatos cover everything from roof replacement to ADU construction, and we run those jobs as a single accountable scope. ADU construction here runs $90,000 – $220,000, and the gap between the low and high end usually comes down to hillside prep, fire-hardening requirements, and whether you choose a prefab line like Abodu or Dvele versus a stick-built custom. Roof replacement runs $8,000 – $20,000, and in the WUI zone, that roof has to meet Class A assembly standards with ember-resistant vents, not just a low per-square shingle quote.
Roof, Window, and Siding Compliance
In the Wildland-Urban Interface, your roof is your home’s first line of fire defense. We spec GAF, CertainTeed, and Owens Corning assemblies that meet Class A standards, and we pair them with venting that blocks embers. Windows along the hillside exposure often need impact or dual-pane ratings through PGT or Therma-Tru, and we’ll tell you which rating your specific street and slope actually require before you spend a dollar.

Kitchens, Baths, and Interior Build-Out
Inside the home, we pull from KraftMaid, Wellborn, Cambria, Silestone, and Caesarstone for kitchens, and Schluter waterproofing, Toto, and Kohler for baths. A walk-in shower in Los Gatos runs $4,500 – $12,000, and the waterproofing behind the tile is the part you’ll never see but will absolutely live with. We build it to last behind the wall.

Trusted Brands We Service in Los Gatos

AfterCommon General Contractor Problems We See in Los Gatos Homes
- Hillside decks pulling off the house. We recently rebuilt a hillside deck off Monte Sereno in 95030 where the original ledger had pulled away from the rim joist after an atmospheric-river storm. Our crew replaced the load-bearing connections with Simpson hardware, added engineered drainage to divert runoff, and installed ember-resistant vents to meet WUI standards, passing inspection sign-off on the first try.
- Flatland roofing and venting that fails WUI review. A roof quoted at San Jose flatland prices often uses venting and edge details that don’t meet Los Gatos Class A assembly requirements. We see this on insurance inspections after the fact, when the homeowner learns their claim is denied because the roof wasn’t WUI-compliant.
- Additions quoted without a geotechnical soils report. On a steep 95033 lot, skipping that report means the foundation design is a guess, and the Town will stop your permit until it’s done. We’ve seen foundation change orders in the tens of thousands that could have been avoided with a $3,000 report up front.
- Century-old downtown homes with unresolved structural retrofits. Knob-and-tube wiring, failing load paths, and foundation settlement in Victorian-era homes near the Boulevard need documented correction, not a cover-up. If the previous renovation never got final sign-off, we’ll find it and bring it into compliance before we add anything on top.

FAQs About General Contractor in Los Gatos
Hillside decks and roofs in Los Gatos generally need to meet the Town’s adopted structural standards for elevated wind exposure, which often means engineered hold-downs, Simpson hardware at load-bearing connections, and roof assemblies rated for uplift along ridgeline lots. The exact rating depends on your slope and exposure, and we’ll spec it from your site plan and soils report. Call (833) 589-8103 for a quote that actually includes that engineering.
WUI code affects your remodel by requiring Class A roof assemblies, ember-resistant vents, and sometimes ignition-resistant siding or decking depending on your location in the 95030 or 95033 wildland interface. That means your material choices get limited to what the Town will approve, and your permit submission needs to document compliance up front. We handle that documentation as part of the normal scope.
You typically need a building permit, a geotechnical soils report if the slope triggers one, structural plans showing the ledger connection and hold-downs, and drainage calculations for concentrated runoff. The Town then inspects footings, framing, and drainage before the deck is surfaced and signed off. Skipping any step means a stop-work order and possible fines. We manage that entire sequence for you.
A compliant Class A roof assembly with documented ember-resistant vents can qualify you for a wildfire mitigation discount with many insurers, and it makes a future claim defensible if a wildfire ever comes through. We hand you the compliance documentation at project close, and you’ll want to keep it with your policy paperwork. For an exact roof replacement quote in Los Gatos, call (833) 589-8103.
A compliant quote includes the geotechnical soils report when required, engineered foundation and drainage design, Class A roofing assembly, ember-resistant vents, Simpson hardware at structural connections, and all permit and inspection fees. If a quote leaves those categories out, they’ll show up later as change orders. Our line-item quotes list them explicitly, so you can compare apples to apples.
