The town's historic Main Street district includes homes with original wood siding that may be over a century old. Restoration and replacement on these properties requires matching period-appropriate profiles and complying with any local design guidelines. Hamilton Exteriors has experience working on historic St. Helena properties, preserving character while upgrading performance and fire resistance.
St. Helena's fire zone designations affect siding choices significantly. Properties in WUI zones must use ignition-resistant siding meeting Chapter 7A standards. James Hardie products meet these requirements without sacrificing the architectural quality that defines this community. Hamilton Exteriors verifies your property's fire zone status and recommends compliant materials.

James Hardie fiber cement siding is the best choice for St. Helena homes in WUI fire zones. It carries a Class A fire rating, does not ignite or melt, and meets California Chapter 7A requirements. Vinyl siding melts at approximately 160 degrees Fahrenheit and is not recommended for properties in Very High FHS
Do I need a permit for siding replacement in St. Helena?
