Home Hardening in Sonoma County in 30 secondsWhat it covers, how we rank

16 home hardening contractors are listed for Sonoma County, ranked below by public Google rating and review count (paid placements are labeled and shown first). Under California PRC 4291, homes in fire hazard severity zones must maintain 100 feet of defensible space — most of these contractors also handle the full clearance scope.

Home hardening means retrofitting the structure itself — roof, vents, gutters, eaves, decks, windows — so wind-blown embers cannot ignite it. Embers, not the flame front, destroy most homes lost in California wildfires, and hardening is what insurers now reward.

Do you need a licensed contractor for this?

Yes, always

Roof, vent, siding, window and deck retrofits are construction work — hire a licensed contractor.

Look for a B General Building license or a specialty class such as C‑39 Roofing or C‑17 Glazing; many jobs also need a building permit.
