Home Hardening Costs
Home hardening involves upgrading the structure itself to resist ember intrusion and radiant heat. Costs vary significantly based on the age of the home, existing materials, and the scope of upgrades required.
| Upgrade Type | Typical Cost | Priority Level |
|---|---|---|
| Ember-resistant vent covers | $300 – $1,200 | 🔴 Critical |
| Class A fire-rated roofing | $8,000 – $25,000 | 🔴 Critical |
| Dual-pane tempered glass windows | $3,000 – $12,000 | 🟠 High |
| Non-combustible deck replacement | $5,000 – $20,000 | 🟠 High |
| Exterior wall siding upgrade | $8,000 – $30,000 | 🟡 Medium |
| Garage door sealing | $500 – $2,000 | 🟠 High |
| Full home hardening package | $8,000 – $35,000 | Varies |
