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.
Redwood City's housing stock ranges from hillside properties in Emerald Hills and Farm Hill to ranch homes in Woodside Plaza and waterfront-adjacent properties in Redwood Shores. This variety means deck projects range from engineered multi-level hillside builds to efficient ground-level patio extensions. Hamilton Exteriors adapts designs to each neighborhood's terrain, architecture, and microclimate.
Redwood City building permits for decks are issued through the Community Development Department. Decks over 30 inches above grade require permits with structural plans. Emerald Hills properties may need geotechnical review and grading permits for hillside construction. Permit timelines average 2 to 4 weeks. Hamilton Exteriors handles all engineering, applications, and inspections.
Deck costs in Redwood City range from $18,000 to $60,000. Composite decking runs $35 to $55 per square foot installed. Redwood costs $30 to $50 per square foot. Ipe hardwood ranges from $50 to $75 per square foot. Emerald Hills multi-level builds with engineered foundations typically run $40,000 to $60,000. We provide free, itemized estimates tailored to your site.
Neighborhoods We Serve
Deck Building Across Redwood City Neighborhoods
Local planning starts with the site, neighborhood context, access, and applicable city review.
Emerald Hills
Emerald Hills elevated lots above Edgewood Road offer panoramic Bay views. Multi-level decks on engineered foundations step down the hillside, creating outdoor rooms at different elevations. These builds transform steep terrain into the most usable and enjoyable space on the property.
Farm Hill
Farm Hill properties on gentle slopes benefit from raised deck platforms that elevate the outdoor area above the yard. The warm microclimate and sun exposure make Farm Hill decks functional year-round. Composite materials handle the mix of sun and occasional coastal moisture.
Woodside Plaza
Woodside Plaza homes have backyards sized for substantial deck installations. Ground-level and slightly raised composite decks create outdoor dining and entertaining spaces that extend the ranch-style homes into generous yard areas.
Edgewood Park Area
Properties near Edgewood Park enjoy proximity to open space and trail access. Decks here serve as outdoor base camps connecting the home to the surrounding natural landscape. Elevated builds on sloped lots capture long-range views over the park preserve.
Redwood Shores
Redwood Shores waterfront-adjacent homes suit ground-level composite decks designed for coastal conditions. Moisture-resistant materials handle the proximity to the lagoons and Bay. These decks extend the indoor living space into sheltered outdoor rooms.
Stambaugh Heller
Stambaugh Heller hillside lots above downtown offer elevated positions with views. Decks here create level outdoor platforms on sloped terrain, adding functional entertaining space. The warm, protected microclimate supports extended seasonal deck use.
Mt Carmel
Mt Carmel properties at higher elevations enjoy sun exposure and open views. Slightly raised composite decks with integrated shade structures work well for homes in this warm area, providing comfortable outdoor spaces from early spring through late fall.
Palm Park
Palm Park family homes have moderate backyards where efficient deck layouts maximize outdoor living area. A well-designed 250 to 400 sq ft deck with built-in seating creates a versatile outdoor room for dining and relaxation.
