Los Gatos sits at the base of the Santa Cruz Mountains where hillside estates command panoramic views of the South Bay valley. This terrain creates some of the most spectacular deck settings in Silicon Valley. Homes on upper hillside lots build multi-level decks with Ipe hardwood and high-end composite materials, creating outdoor living spaces that rival the quality of the home interior.

What Types of Decks Does Hamilton Exteriors Build?
Composite Decks
Low-maintenance Trex and TimberTech composite decking that resists fading, staining, and mold. 25-year manufacturer warranty with no annual sealing required.
Hardwood Decks
Ipe, redwood, and cedar decks with natural beauty and durability. Ideal for Bay Area homes where the deck is the centerpiece of outdoor living.
Multi-Level Decks
Tiered deck designs for hillside and sloped lots — common across the East Bay hills, Marin, and Peninsula. Engineered for Bay Area soil and seismic conditions.
Deck Remodels & Repairs
Replace rotting boards, upgrade railings, add built-in seating, and bring aging decks up to current code. Most deck remodels complete in 2 to 4 weeks.
Los Gatos homeowners invest in premium materials and architectural deck design. Ipe (Brazilian walnut) hardwood is especially popular here for its 40+ year lifespan, rich coloring, and natural resistance to decay. TimberTech and Trex premium composite lines offer a maintenance-free alternative with realistic wood grain patterns. We design decks that integrate with the home architecture, not just bolt on.
Los Gatos building permits are issued through the Town of Los Gatos Community Development Department. Hillside properties require structural engineering, and many trigger design review for exterior modifications. The hillside development standards guide deck construction on steep terrain. Permit timelines average 3 to 6 weeks. Hamilton Exteriors navigates the design review and permitting process.
Deck costs in Los Gatos range from $25,000 to $60,000, reflecting the premium materials and architectural design standards typical for this market. Composite decking runs $40 to $55 per square foot installed. Ipe hardwood ranges from $55 to $75 per square foot. Multi-level hillside builds with engineered foundations, glass railings, and integrated lighting typically run $45,000 to $60,000.
Neighborhoods We Serve
Deck Building Across Los Gatos Neighborhoods
Local planning starts with the site, neighborhood context, access, and applicable city review.
Los Gatos Hills
Los Gatos hillside estates offer premium deck settings with Santa Cruz Mountain views. Multi-level Ipe and composite decks on engineered foundations create resort-quality outdoor living spaces. These builds are among the most architecturally ambitious deck projects in the South Bay.
Belgatos
Belgatos properties on moderate hillside grades suit elevated deck platforms that capture foothill views. The neighborhood tree cover provides natural shade framing. Premium composite and hardwood materials match the refined aesthetic of this established neighborhood.
Shannon
Shannon neighborhood homes have generous yards where expansive deck designs accommodate outdoor kitchens, fire features, and multiple seating areas. The warm microclimate below the hills makes year-round outdoor entertaining a natural part of life here.
Kennedy
Kennedy area homes on hillside lots benefit from multi-level deck systems with stairs connecting the house to different yard elevations. These decks transform sloped backyards into functional, tiered entertainment spaces with mountain views.
Los Gatos Downtown
Downtown Los Gatos homes near North Santa Cruz Avenue have smaller lots where efficient deck design is essential. A well-planned 200 to 350 sq ft deck creates an intimate outdoor dining space that extends the home living area.
Blossom Hill
Blossom Hill family homes have backyards suited for 300 to 500 sq ft composite decks. Low-maintenance materials are popular for households with children. Shade pergolas integrate with the deck to manage summer heat while maintaining open-air feel.

We serve Northern California across three regions: the San Francisco Bay Area, Greater Sacramento, and the Central Valley. Our published guides cover 14 counties and 88 cities. Our Castro Valley and Sacramento offices support local estimating, permit coordination, and project planning across these regions.
How does billing and financing work?
Financing may be available for eligible projects with approved credit. Available terms depend on lender approval, project scope, and current programs. Your project manager can review the options that apply before work begins. We also accept checks, ACH, and major credit cards.
Are you licensed and insured?

How much does a deck cost in Los Gatos?
A typical Los Gatos deck costs $25,000 to $80,000 for a 400 to 800 square foot deck, depending on material, height above grade, and site access (Hamilton Exteriors 2024-2026 project data). Composite decks on flat lots at the lower end; redwood or Ipe decks on hillside properties at the higher end. Get a precise estimate with a free on-site consultation.
Do I need a permit for a deck in Los Gatos?
Yes. Los Gatos requires a building permit for any deck over 30 inches above grade or attached to the house. The Los Gatos Building Department handles permitting. Hamilton Exteriors pulls all permits on your behalf.
What is the best deck material for Los Gatos?
Composite decking (Trex, TimberTech) is the most popular choice for Los Gatos homes. It handles the hot summers without splintering, requires no staining or sealing, and resists the moisture from coastal fog that rolls in through the Santa Cruz Mountains gap. Redwood remains a strong choice for traditional homes.
How long does it take to build a deck in Los Gatos?
Most Los Gatos decks take 2 to 4 weeks from start to finish, depending on size and complexity. Permit approval adds 1 to 3 weeks. We schedule construction during the dry season (April through October) for best results.
Can you build a deck on a sloped Los Gatos lot?
Yes. We regularly build decks on hillside properties throughout Los Gatos. Steep lots require additional structural engineering, deeper footings, and sometimes retaining walls. We include all of that in our estimate.
