Why Spokane Homeowners Choose Composite

Composite decking is the top choice for homeowners who want the look of wood without the upkeep. It resists fading, staining, and moisture—so it won’t rot, crack, or warp through hot summers and snowy winters. You’ll spend more time enjoying your deck and less time maintaining it.

Durable in all seasons: Performs in Spokane heat and CDA snow.
Low maintenance: Soap-and-water cleaning—no annual staining.
Great long-term value: Higher upfront, lower lifetime cost.
Sustainable: Many boards use recycled content.

Composite Deck FAQs

How long do composite decks last here?

Well-installed composite decks commonly last 25–30+ years. Many products include fade and stain warranties; ask which boards fit your goals and budget.

Do composites get hot in summer?

Darker boards run warmer than light wood. Choosing lighter colors and newer heat-mitigating caps noticeably reduces surface temps.

Can you mix colors or add inlays?

Yes. Picture-frame borders, color inlays, and contrasting stairs are popular design options that we build often.
