What areas do you serve?
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?
Yes. Hamilton Exteriors holds CSLB License #1078806, active general liability coverage, and the required contractor bond. We also hold GAF Master Elite and James Hardie Elite Preferred credentials. We can provide current proof of coverage before work begins.
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 San Leandro?
Yes. San Leandro requires a building permit for any deck with a walking surface more than 30 inches above grade. Decks under 30 inches may still require a permit if attached to the house. Hamilton Exteriors handles all permit applications and inspections. Permit fees typically run $400 to $1,200 (Hamilton Exteriors 2024-2026 project data).
How much does a deck cost in San Leandro?
A typical San Leandro deck costs $12,000 to $26,000 for a 400-square-foot composite deck, including footings, framing, decking, railings, stairs, and permit fees (Hamilton Exteriors 2024-2026 project data). Wood decks run $8,000 to $18,000 for the same size. Premium materials and complex designs increase the cost.
What is the best deck material for San Leandro's climate?
Composite decking is the most popular choice for San Leandro homes. It resists moisture from fog and rain, does not require annual sealing, and carries a 25- to 50-year warranty. For homeowners who prefer natural wood, cedar and Ipe perform well in San Leandro's mild climate with proper maintenance.
How long does it take to build a deck in San Leandro?
Most residential decks take 2 to 4 weeks from permit approval to completion. A simple ground-level deck may take 1 to 2 weeks. Multi-level decks, decks with roofs or pergolas, and hillside decks can take 4 to 6 weeks. Permit processing adds 2 to 4 weeks before construction begins.
Does a deck add value to a San Leandro home?
Yes. A well-designed, code-compliant deck adds usable outdoor living space that Bay Area buyers value highly. According to the National Association of Realtors, a wood deck recovers roughly 65 to 75 percent of its cost at resale nationally. In San Leandro's competitive market, a quality deck can be a deciding factor for buyers.
