Most decking comparisons are written for homeowners in the Mid-Atlantic or Pacific Northwest — climates where the math looks different from ours. Colorado Springs isn’t like those markets. We get 300+ days of sun per year at 6,035 feet where UV radiation is roughly 25% more intense than at sea level. We see 100+ freeze-thaw cycles annually and temperature swings of 40°F+ in a single day. These conditions change the calculation significantly, and most generic composite vs. wood articles don’t account for any of them.
Upfront Cost: What You’ll Actually Pay
For a standard 300 sq ft deck, including framing, decking boards, standard railings, and labor:
| Material | Per Sq Ft | 300 sq ft Deck | Lifespan in Colorado |
|---|---|---|---|
| Pressure-Treated Pine | $40–$55 | $12,000–$16,500 | 10–15 years |
| Cedar | $50–$70 | $15,000–$21,000 | 12–18 years |
| Mid-Range Composite (Trex, Fiberon) | $55–$80 | $16,500–$24,000 | 25–30 years |
| Premium Composite (TimberTech, AZEK) | $75–$100+ | $22,500–$30,000+ | 30–50 years |
These figures don’t include PPRBD permit costs ($225–$500 for most residential decks), optional features like built-in lighting or stairs, or any needed structural work at the house connection point.
At first glance, wood looks like the clear winner on upfront cost. A pressure-treated deck comes in $3,000–$8,000 less than mid-range composite on a standard build. But that’s the beginning of the story.
The Number Most Articles Skip: Maintenance Cost
A wood deck in Colorado Springs needs re-staining every 2–3 years — not the 4–5 year cycle that stain manufacturers print on the can. At our altitude, UV breaks down stain 30–40% faster than at sea level. A professional re-stain runs $450–$850 per application. Over 10 years, that’s three to four applications totaling $1,350–$3,400 in staining alone, before accounting for board replacement, rail repairs, or structural fixes.
Add annual cleaning, minor board replacement as wood checks and splits, and one or two spot repairs to flashing and ledger connections, and a realistic 10-year maintenance budget for a wood deck in Colorado Springs is $500–$1,000 per year. Composite requires occasional soap-and-water cleaning — typically $50–$150 per year.
The standard advice of “stain your deck every 3–5 years” doesn’t apply here. At 6,035 feet with 300+ days of sun and 40°F+ daily swings, we consistently see wood decks showing significant UV breakdown and surface checking by year 2–3 if they’re not maintained on schedule. South-facing and west-facing decks degrade even faster.
The True 20-Year Cost Comparison
| Material | Install | 20-Year Maintenance | Replace? | 20-Year Total |
|---|---|---|---|---|
| PT Pine | $14,000 | $12,000 | Yes — likely once | ~$40,000 |
| Cedar | $18,000 | $10,000 | Possibly | ~$30,000+ |
| Mid-Range Composite | $20,000 | $2,000 | No | ~$22,000 |
| Premium Composite | $26,000 | $1,500 | No | ~$28,000 |
The financial case for composite strengthens significantly when maintenance costs are factored in. The crossover point — where composite’s lower ongoing costs offset the higher upfront investment — typically hits around years 7–10 in Colorado’s climate.
Where Wood Still Makes Sense
Cost isn’t the only variable. Wood makes sense when: budget constraints make the upfront difference significant, the deck is a secondary or utility structure where longevity matters less, or the aesthetic of natural wood is a non-negotiable priority. Cedar in particular has a warmth that quality composite approximates but doesn’t fully replicate.
Wood also makes sense for horizontal deck boards on structures where the framing is the main investment and the decking is expected to be replaced. Pressure-treated framing is the right call regardless of what goes on top — we use UC4B spec posts for any ground-contact framing given Colorado’s 36-inch frost line.
Composite Product Tiers: What the Price Difference Buys
Mid-range (Trex Select, Fiberon Concordia): Solid or hollow composite boards. Good UV resistance. 25-year fade and stain warranty. Gets warm in direct sun — a real consideration for south-facing Colorado decks where surface temps can push 130°F+ on peak summer days.
Upper mid-range (Trex Transcend, Fiberon Paramount): Better UV stability, more realistic wood grain appearance, capped construction that resists moisture and staining more effectively. This is where most of our deck builds land — the quality-to-cost ratio is strong.
Premium (TimberTech AZEK, Wolf PVC): Full cellular PVC or premium capped composite. Coolest surface temperatures of any composite. 50-year warranties. Significantly better performance in Colorado’s UV environment over multi-decade ownership. The right call for high-use primary decks on homes where longevity is the priority.
Framing: The Part That Matters Most
Regardless of what goes on the surface, the framing determines how long the deck lasts. In Colorado Springs: all posts in ground contact require UC4B pressure-treated lumber (not UC3 or unmarked lumber), footings must go below the 36-inch El Paso County frost line, and ledger connections to the house require proper flashing and approved hardware.
