Cedar vs Composite Decking

Why this page exists

The romance-vs-practicality fork

Cedar is the material people fall for; composite is the one they stop thinking about. Both are correct answers to different questions.

Honest lifetime pricing

Cedar’s lower install price meets a stain-every-2–3-years reality. We put both numbers on the table instead of just the first one.

How each one ages

Cedar silvers; composite holds. Neither is wrong, but you should choose the aging curve on purpose, not discover it.

Your yard, both boards

Warm cedar tones and composite’s engineered palette photograph completely differently against the same siding. Render both and see.

Cedar vs Composite Decking

Quick answer: cedar installs cheaper ($30–$50 per square foot against composite’s $45–$70), feels and smells like the real wood it is, and stays cool underfoot, in exchange for staining every 2–3 years and a 15–20 year life. Composite costs more once, then mostly leaves you alone for 25–30. The full ledger:

The verdict

Choose cedar if you love wood enough to keep a date with it every couple of years. Nothing engineered matches its feel, and the price of entry is the lowest of the premium looks. Choose composite if the deck should be furniture, not a hobby. Either way, decide with your eyes: render your own backyard in warm cedar and in a composite palette, side by side, before anyone orders boards.

Cost assumptions and sources

U.S. planning allowances in USD for a simple, single-level deck, including ordinary materials and contractor labor. These are PaperPlan editorial assumptions, not surveyed averages or a local quote.

• Pressure-treated: $25 – $40 / sq ft installed (USD)
• Composite: $45 – $70 / sq ft installed (USD)
• PVC: $60 – $90 / sq ft installed (USD)

Multiply deck area (width × length in feet) by the selected installed rate, then round each end of the range to the nearest $100.

Demolition, permits and engineering, taxes, stairs, railing, roofs, unusual foundations and difficult site access need separate quotes. Location, product selection and labor can put a real bid outside these ranges. Canadian projects need local CAD pricing.

Common questions

Is cedar cheaper than composite?

Upfront, yes: cedar installs around $30–$50 per square foot against composite’s $45–$70. Over 15 years the gap narrows or flips: every stain cycle costs a weekend or a few hundred dollars professionally, and cedar will likely want replacement around the time composite hits mid-warranty. Short horizon favors cedar; long horizon usually favors composite.

How long does a cedar deck last?

A well-maintained cedar deck runs 15–20 years; a neglected one shows its age far sooner, especially at ground contact and fasteners. The maintenance isn’t optional with cedar. It is the lifespan. Composite’s 25–30 year warranties assume you do nothing but wash it.

Can I just let cedar go gray?

You can. Cedar silvers evenly, and lots of owners choose the driftwood look on purpose. Skipping stain trades color for patina, not for durability: you’ll still want water repellent periodically, and surface checking and splinters develop faster on untreated boards. It’s a legitimate aesthetic, chosen deliberately.

Which looks better, cedar or composite?

Cedar wins on romance: real grain, real warmth, a smell composite will never have. Composite wins on consistency: no knots, no cupping, the same color in year eight. Against your particular siding and light, one of them will simply look right. Render both on a photo of your yard and trust your first reaction.
