Siding Contractor in Castro Valley

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.

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.

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.

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.

The price depends on the siding system, exterior wall area, access, and the condition behind the existing cladding. Ask the written estimate to distinguish siding replacement from stucco repair or waterproofing work. Confirm which removal, repair, trim, and cleanup costs it includes.

For a typical 2,000 sq ft Castro Valley home, vinyl siding runs $12,500 to $17,500, James Hardie fiber cement runs $21,000 to $28,000, and stucco re-application runs $19,500 to $24,000 (Hamilton Exteriors 2024-2026 project data). All prices include tear-off, weather barrier, materials, labor, trim, and cleanup. Multi-story homes add $1,500 to $4,000 for scaffolding. Every Hamilton Exteriors estimate is fully itemized.

Yes. Most siding replacement projects require a permit from the Alameda County Building Inspection Department. Permit fees typically range from $200 to $600. Hamilton Exteriors handles the entire permit process, including application, plan submission, and scheduling inspections.

For most Castro Valley homes, yes. Fiber cement lasts 50-plus years versus 20 to 30 for vinyl, delivers 86% ROI at resale (Remodeling Magazine 2024), carries a Class A fire rating, and resists Castro Valley's marine layer moisture better than any alternative. The higher upfront cost pays for itself through longer lifespan and higher resale return.

James Hardie fiber cement siding projects typically run 1 to 2 weeks. Vinyl siding is faster, usually 3 to 5 days. Every project includes removal of old siding, inspection and repair of underlying sheathing, installation of a weather-resistant barrier, new siding, and trim and caulking. We work in sections so exposed walls are never left unprotected overnight.
