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.
Larkspur's housing stock spans 8% pre-1940, 20% 1940-1959, 35% 1960-1979. Architectural styles range from 1950s-60s California ranch homes in Greenbrae to postwar subdivisions in Bon Air and Murray Park. Each era and style presents different decks requirements — from material compatibility to structural considerations. Our crews know what to expect before they arrive on site.
Decks Across Larkspur Neighborhoods
Local planning starts with the site, neighborhood context, access, and applicable city review.

How does billing and financing work?

Are you licensed and insured?

Do I need a permit for my exterior project?
Permit requirements depend on the project scope and local jurisdiction. Hamilton Exteriors coordinates required applications, plan documents, corrections, and inspections. Permit fees and allowances appear in the proposal before construction begins.
How much does a deck cost in Larkspur?
A typical 300 to 500 square foot deck in Larkspur costs $9,000 to $50,000 depending on material (Hamilton Exteriors 2024-2026 project data). Composite decks on a standard lot run $15,000 to $42,000. Hillside properties with access challenges or structural reinforcement needs cost more. We provide itemized estimates for every project.
Do I need a permit for a deck in Larkspur?
Yes. The City of Larkspur Building Division requires a permit for any deck over 30 inches above grade or attached to the house. We handle the permit application and all inspections for you.
What is the best deck material for Larkspur's climate?
Composite decking from Trex or TimberTech is the best choice for most Larkspur homes. It resists the coastal moisture that causes wood rot, requires no annual sealing, and is available in Class A fire-rated options for WUI zones. For natural wood, Ipe offers the best durability and fire resistance.
How long does it take to build a deck in Larkspur?
Most decks take 1 to 3 weeks of construction time. Permit processing adds 2 to 4 weeks before construction can begin. We provide a timeline estimate during the consultation.
Can you build a deck on a hillside property in Larkspur?
Yes. We have built decks on steep hillside properties throughout Marin County. These projects require additional structural engineering for foundation and lateral bracing. We include this in our design and estimate.
