FAQ
James Hardie Siding in Angwin — FAQ
It is the defining factor. Angwin sits in dense forest on Howell Mountain, and the 2020 Glass Fire burned across this area, so we apply rigorous fire-first hardening and current WUI standards on every project here.
Class A non-combustible fiber cement, detailed uncompromisingly at eaves, soffits, vents, decks, and ground-to-wall transitions where embers and leaf litter collect under the tree canopy.
No. Given the standing timber surrounding homes on Howell Mountain, we will not install combustible cladding here — hardened, non-combustible assemblies are the only responsible choice.
Re-cladding combustible wood or T1-11 in hardened non-combustible fiber cement is typically the single highest-value structural improvement available to a forested ridge home.
Yes — the ridge runs hot, dry, and high-UV in summer, so we pair fire hardening with high-UV factory finishes and corrosion-aware fasteners built for sustained dry-season exposure.
We build to current WUI standards and document every assembly so the work supports defensible-space, code, and insurability conversations; insurers set their own criteria, which we don't speak for.
