Composite Decking: What You Need to Know



Composite Decking in Colorado: What to Know

Looking for a deck that looks great year-round and doesn’t eat your weekends? For many Denver homeowners, composite decking is the best balance of beauty, durability, and low maintenance. Northern Lights Exteriors designs and builds composite decks tailored to Colorado’s high-altitude sun, freeze–thaw cycles, and afternoon storms—so you can spend more time enjoying the space and less time maintaining it.

Bottom line: Composite costs more up front than most wood options, but it typically wins on total cost of ownership in Denver’s climate—and it keeps its color and shape with minimal upkeep.

Why Composite Decking Works So Well in Denver

  • UV & Heat Resilience: Many composite lines include UV inhibitors and lighter colorways to mitigate surface heat.
  • Moisture Resistance: Capped boards and hidden fasteners help block water intrusion and swelling.
  • Freeze–Thaw Stability: Dimensional stability means fewer checks and cups when temps swing.
  • Low Maintenance: No annual staining or sealing—just wash as needed.
  • Consistent Look: Color-blended grain patterns hold up aesthetically over time.

Board Families & Upgrades

We help you choose a board family that hits your target look, budget, and performance. Common options include:

Design Options Denver Homeowners Love

  • Layouts: Single-level, multi-level, or wraparound with integrated stairs.
  • Railings: Sleek black aluminum, horizontal cable, or composite post + cap systems.
  • Borders & Inlays: Picture-frame edges, color-contrast inlays, and breaker boards.
  • Lighting: Post caps, stair lights, under-rail LEDs for safe evening use.
  • Shade & Privacy: Pergolas, shade sails, and privacy screens tuned to your orientation.

  5. Final Walkthrough & Warranty: Documentation, care guide, and manufacturer registration.

Cost & ROI: The Denver Math

Composite decking usually carries a higher materials cost than entry-level wood, but annual ownership costs are far lower. Skip the stain/seal cycles and board replacements and you typically break even within a few seasons—then save money (and time) every year after. Composite’s “low-maintenance” appeal can also boost resale value.

Care & Maintenance (Simple)

  • Rinse with water and mild soap as needed; avoid harsh solvents or metal shovels.
  • Use breathable outdoor rugs; keep gaps clear for drainage and airflow.
  • Schedule a spring check: tighten fasteners, inspect railings, verify lighting.

Budget Ranges by Size (Planning Estimates)

Final pricing depends on site conditions, framing needs, stairs/railings, lighting, access, and selections. These ballparks help with early planning—your written proposal will be specific to your home.

Typical SizeGoodBetterBest
12′ × 12′ (~144 sq ft)$7k–$11k$11k–$16k$16k–$22k
16′ × 16′ (~256 sq ft)$12k–$18k$18k–$26k$26k–$36k
20′ × 20′ (~400 sq ft)$19k–$28k$28k–$40k$40k–$58k

Good = dependable capped composite and standard railings. Better = upgraded colorways, hidden fasteners, picture-frame borders. Best = premium boards (incl. PVC options), designer railings, lighting, fascia, and custom details.

Denver Permitting & HOA Basics

  • Engineered drawings: Required for many projects—our team coordinates when needed.
  • Setbacks & height: We verify zoning rules and guard/handrail codes before design is finalized.
  • HOA submissions: We assemble color/rail samples and elevations to streamline approvals.
  • Inspections: Typical milestones include footings, framing, and final—scheduled around weather.

Composite Decking FAQ

Is composite too hot for bare feet?

Lighter colorways, shade elements, and airflow under the deck keep surfaces more comfortable. We’ll guide you on the right combo for your exposure.

Can composite be used with an existing frame?

Often, yes—after a framing inspection for span, spacing, and hardware. We’ll confirm whether your frame meets current code and manufacturer specs.

What about wildlife and pests?

Composite resists insects and does not splinter. Proper flashing and screening help keep critters out of under-deck spaces.
