Wildfire-resistant decks resist ignition from embers that collect on the surface and underneath. Blaze Blocker retrofits or rebuilds decks with Class A and B composite decking, fire-retardant-treated wood, non-combustible soffit systems, and ember screen skirting — all CWRC-compliant.
The space under a deck is a common ignition trap: embers blow in, land on debris, and ignite the home from below. Sealing and screening that zone is as important as the deck surface itself.
Why decks ignite first
A traditional wood deck is a horizontal ember bed attached directly to the house. Embers settle into gaps between boards and into debris underneath, smolder, and ignite the structure — often before the fire front arrives.
Hardening the deck means addressing three things together: the walking surface, the framing and soffit, and the under-deck zone.
Insurance carriers treat exterior decks as a distinct wildfire hazard: they are typically built from combustible materials and attached directly to the home, so a deck that catches embers can carry fire straight to the structure. As coverage tightens across Colorado, a hardened, documented deck can ease underwriting and support mitigation discounts.
Deck systems and upgrades we install
- Class A & B composite decking — Fire-rated composite boards that resist ignition and won't feed a fire.
- Fire-retardant-treated (FRT) wood — Treated lumber for homeowners who want a wood look with improved fire performance.
- Non-combustible deck soffit — Closes the underside so embers can't lodge in framing.
- Ember screen skirting — Fine metal mesh that seals the under-deck zone against blowing embers.
All materials and installation methods meet the Colorado Wildfire Resiliency Code (CWRC). We document completed work so your insurer can use it for premium review, and align every project with the IBHS Wildfire Prepared Home™ standard.
Retrofit or rebuild?
Many decks can be retrofitted — replacing the surface, enclosing the soffit, and adding ember skirting — without a full teardown. Older or structurally tired decks are often better rebuilt to a fully fire-rated assembly.
We assess your deck for free and recommend the most cost-effective path that brings it into CWRC compliance.
