Popular Deck Materials for Northern Colorado

Northern Colorado's climate demands materials that resist fading, warping, and moisture damage. Based on local trends and expert recommendations, here are the top options:

Composite Decking (e.g., Trex, TimberTech)

Composite decking, made from recycled wood fibers and plastic, is a top choice for Longmont homes. It's engineered for durability and mimics the look of natural wood without the upkeep.

Pros: Low maintenance (no staining or sealing needed), resistant to fading, splintering, mold, insects, and weather extremes; long lifespan (25–50 years); eco-friendly.
Cons: Higher upfront cost; can get hot in direct sun; some brands may scratch easily.
2026 Cost: $30–$60 per sq ft installed (national average for a full deck: $5,100–$11,200).

Natural Wood (Cedar or Redwood)

Cedar and redwood offer a classic, natural aesthetic that blends with Colorado's landscapes. These softwoods are naturally resistant to decay but require more care in harsh climates.

Pros: Beautiful natural grain and color; affordable; easy to customize with stains; environmentally friendly if sustainably sourced.
Cons: High maintenance (annual sealing/staining); prone to warping, splintering, fading, and insect damage; shorter lifespan (10–20 years).
2026 Cost: $20–$42 per sq ft installed.

Pressure-Treated Pine

This budget-friendly wood is chemically treated to resist rot and insects, making it a common choice for entry-level decks in Boulder County.

Pros: Lowest cost; widely available; easy to install and paint/stain.
Cons: Higher maintenance; susceptible to warping, cracking, and splintering; can fade or discolor; chemicals may leach over time.
2026 Cost: $15–$30 per sq ft installed (cheapest option).

PVC Decking

Fully synthetic PVC (polyvinyl chloride) decking is similar to composite but without wood fibers, offering superior moisture resistance for snowy Northern Colorado winters.

Pros: Extremely durable and waterproof; low maintenance; fade- and stain-resistant; lightweight.
Cons: Higher cost; can feel less natural; expands/contracts with temperature changes.
2026 Cost: $40–$70 per sq ft installed.

Aluminum Decking

Aluminum is a premium, metal-based option ideal for high-end decks in areas like Longmont, where fire resistance and longevity are priorities.

Pros: Virtually indestructible; fireproof; low maintenance; won't rot, rust, or attract insects; excellent for sloped or elevated decks.
Cons: Most expensive; can get very hot in summer sun; noisier underfoot; limited color options.
2026 Cost: $50–$80+ per sq ft installed.
