Novato Siding Services
Fiber Cement Siding (James Hardie)
James Hardie fiber cement is our most recommended siding material for Novato homes. It resists moisture, fog, salt air, and temperature swings that cause wood and vinyl to deteriorate. Fiber cement delivers an 86% return on investment at resale according to Remodeling Magazine's 2024 Cost vs. Value Report. Available in HardiePlank lap siding, HardieShingle, and HardiePanel vertical styles.
Vinyl Siding
Premium CertainTeed and Ply Gem vinyl in 60-plus colors and textures. The best value for a fresh, low-maintenance exterior. Vinyl siding runs $975 to $1,275 per 100 sq ft installed (Hamilton Exteriors 2024-2026 project data). Ideal for budget-conscious projects where fire zone compliance is not required.
Stucco Siding
Traditional three-coat stucco and EIFS for Mediterranean, Spanish Colonial, and Craftsman homes. Lasts 50 to 80 years with proper care. Stucco remediation and re-application averages $1,950 per 100 sq ft (Hamilton Exteriors 2024-2026 project data).
Exterior Waterproofing
Complete exterior moisture protection including elastomeric coatings, flashing, and foundation membranes. We install a full weather-resistant barrier (WRB) system behind every siding project, creating a continuous drainage plane that channels water down and out.

Novato-Specific Considerations for Siding
Fire Risk and WUI Compliance
Most of Marin County, including large portions of Novato, is designated as Wildland-Urban Interface (WUI) High or Very High Fire Hazard Severity Zones (FHSZ) by CAL FIRE. Homes in these zones must comply with California Chapter 7A building standards, which require Class A fire-rated materials for both roofing and siding.
Fiber cement siding is the clear choice for Novato homes in WUI zones. It carries a Class A fire rating and will not melt or ignite like vinyl. Combined with a Class A roof, it gives you full-perimeter fire protection that meets Chapter 7A requirements. Vinyl siding is not recommended for homes in high or very high fire hazard zones.
Climate Factors
Novato sits inland from the coastal fog belt that affects Mill Valley and Larkspur. The climate is drier and warmer, with summer temperatures regularly exceeding 90 degrees. This inland heat can cause vinyl siding to warp and buckle over time, especially on south- and west-facing walls. Fiber cement siding handles these temperature swings without warping, cracking, or melting.
The drier climate also means less moisture-related wear on siding compared to coastal Marin cities. However, Novato's proximity to the San Pablo Bay means occasional salt-laden fog, which can accelerate corrosion on exposed metal flashing. We use corrosion-resistant flashing materials on every Novato project.
Seismic Considerations
Marin County sits near the western edge of the San Andreas Fault. Most of Marin, including Novato, is classified as moderate seismic risk. Proper siding installation includes secure attachment to the building frame, which is critical for seismic performance. Our crews follow manufacturer-specified fastening patterns and use corrosion-resistant fasteners to ensure your siding stays secure during seismic events.
Permit Requirements
The City of Novato Community Development Department requires building permits for siding replacement projects. Permit fees in Novato typically range from $200 to $600 depending on project scope. We handle the entire permit process: application, plan submission, and scheduling inspections. Permit fees appear as a separate line item in your estimate.

Prices include removal of existing siding, new weather barrier, materials, labor, trim, and cleanup. Actual pricing varies based on home size, stories, architectural details, and access. Multi-story homes require scaffolding, which adds $1,500 to $4,000 to the project cost (Hamilton Exteriors 2024-2026 project data). Homes with significant dry rot or water damage behind the existing siding will also need sheathing repairs before new siding is installed.
A typical 2,000 sq ft Novato home costs $12,500 to $28,000 for full siding replacement depending on the material chosen and the number of stories (Hamilton Exteriors 2024-2026 project data). Contact us for an itemized estimate.
Why Fiber Cement Is the Right Choice for Novato
James Hardie developed its HZ5 fiber cement formula specifically for coastal and high-humidity climates like the Bay Area. It resists moisture, fog, salt air, and temperature swings that cause wood and vinyl to deteriorate. Fiber cement siding delivers an 86% return on investment at resale, making it one of the highest-ROI exterior upgrades available.
For Novato homes in WUI fire zones, fiber cement's Class A fire rating is essential. It will not melt or ignite like vinyl, and it provides full-perimeter fire protection that meets Chapter 7A requirements.
