What Altadena homes are up against.
Altadena spreads across the foot of the San Gabriel Mountains, where canyon winds pour out of the forest.
The January 2025 Eaton Fire destroyed thousands of structures in Altadena during a severe wind event.
Many Altadena homeowners have been non-renewed or pushed onto the California FAIR Plan. California's Safer from Wildfires rules require insurers to recognize qualifying mitigation, and a documented, hardened home gives your broker a real case for the admitted market.

Where we start here.
Every plan is custom, but these are the layers that do the most for homes in Greater Los Angeles.
Vents and gutters
Santa Ana winds can drive embers a mile ahead of the front. Vents are the first opening to close.
LAYER 01Autonomous sprinklers
Keeps roofs and eaves wet through hours of ember storm while you are evacuated.
LAYER 02Fire-retardant paint
Protects wood siding, eaves and decks common on canyon homes.
LAYER 04Window laminates
View-facing glass is exposed to radiant heat from the canyon below.

[ 04 ]Homeowner checklist
Wildfire hardening checklist for Altadena homes.
In Southern California, Santa Ana wind events are most common from fall into winter, and some of the most destructive fires have burned in those months. The best time to harden is before the winds arrive.
- Replace attic, soffit and foundation vents with 1/16 to 1/8 inch ember-resistant mesh.
- Clear the five feet around the house of mulch, wood and dense shrubs.
- Protect canyon-facing glass with heat-resistant laminates or tempered panes.
- Coat wood eaves, siding and decks with an intumescent fire-retardant finish.
- Add an off-grid sprinkler system fed by your pool or a dedicated tank.
- Document every upgrade for your broker and insurer.
