Class A fire-rated decks
A deck attached to the house can carry fire straight to the wall. We build and rebuild decks with Class A fire-rated materials: TimberTech composite or fire-retardant-treated cedar.
Decks collect embers on the surface, between boards and underneath, where leaves and stored items add fuel. Because decks attach directly to the house, a burning deck puts flame right against the siding, the door and the windows.
We use two Class A fire-rated decking options. Class A fire-rated TimberTech composite is low-maintenance and doesn't need sealing or staining. Class A fire-retardant-treated cedar keeps the look of real wood with a factory fire treatment. Either way, we protect or enclose the area underneath, keep the space beneath clear, and build noncombustible transitions where the deck meets the house. For decks in poor condition, we rebuild from the framing up, with structural repair done right.
What affects the scope
Every property is different, so we price from a site visit rather than a guess. These are the things that change the scope and cost most.
- Deck size and height
- Condition of framing and footings
- TimberTech composite versus treated cedar
- Slope beneath the deck
- Connection to siding and doors
TimberTech or treated cedar?
Both carry a Class A fire rating, the highest flame-spread class. The choice comes down to look, maintenance and budget, and we'll walk you through samples of each.
- Class A fire-rated TimberTech composite: no sealing or staining, consistent color, long warranty.
- Class A fire-retardant-treated cedar: the warmth of real wood with a factory fire treatment.
Common questions
What does Class A fire rated mean?
Class A is the highest flame-spread rating for building materials. It means the material resists the spread of flame far better than standard decking. No deck is fireproof, but Class A materials combined with a protected underside and noncombustible transitions make a deck far less likely to carry fire to the house.
Is all composite decking fire-rated?
No. Many composite and PVC boards are not Class A rated. We use Class A fire-rated TimberTech products, so you're not guessing about the rating.
Can you harden my existing deck instead of replacing it?
Often, yes. If the framing is sound, we can replace the surface with Class A decking, protect the underside and fix the house connection. If the framing is compromised, we will show you why rebuilding is the better choice.
What about the area under the deck?
Keeping it clear of combustibles is critical. We can enclose it with noncombustible materials or leave it open and treat the ground surface, depending on the site.
