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.
Napa's housing stock spans 10% pre-1920, 15% 1920-1950, 40% 1950-1980. Architectural styles range from late 1800s Victorians and Queen Annes in Old Town to 1950s-60s ranch homes in Browns Valley and Westwood. 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 Napa Neighborhoods
Local planning starts with the site, neighborhood context, access, and applicable city review.
Oxbow District
Oxbow District homeowners frequently choose Hamilton Exteriors for decks. Class A fire-rated materials required in expanding WUI zones east and north of the city. With Napa's Valley floor with temperature inversions trapping cold air in winter (frost) and heat in summer, material selection in Oxbow District requires local expertise.
Alta Heights
In Alta Heights, homes are predominantly 1950s-60s ranch homes in Browns Valley and Westwood. Ember-resistant vents and non-combustible fascia required. Our crews are familiar with Alta Heights's architectural character and building requirements.

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?

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.
Do I need a permit for a deck in Napa?
Yes. Any deck attached to your home or over 30 inches above grade requires a permit from the City of Napa Building Division. Permit fees typically run $400 to $1,200. We handle the entire permit process for you.
What is the best deck material for Napa's fire zone?
For Napa properties in Very High FHS
How long does it take to build a deck in Napa?
Most residential decks take 2 to 4 weeks from start of construction to final inspection, depending on size and complexity. Permitting adds 2 to 4 weeks before construction begins. A simple ground-level deck may take as little as 1 week to build.
Can you build a deck on a hillside in Napa?
Yes. Many Napa properties have sloped lots, especially in the Silverado and Mount George areas. Hillside decks require additional engineering for foundations and lateral support. We have experience with stepped foundations, helical piers, and cantilevered designs.
Does a deck add value to a Napa home?
According to the National Association of Realtors, a new wood deck recovers approximately 75% of its cost at resale nationally. In Napa's premium real estate market, a well-designed deck with outdoor living space can be a significant selling point.
