For most US\/Canada homeowners building a 300 to 500 sq ft deck, the decision is whether to spend an extra $1,500 to $3,000 now to skip the maintenance for the next two decades.<\/p>\n<p>Here is the direct answer: in most US climates (zones 3 to 7), <strong>pressure-treated southern yellow pine runs $15 to $25 per square foot installed<\/strong>, while <strong>composite decking (Trex, TimberTech, Fiberon) runs $25 to $45 per square foot installed<\/strong>. Wood needs staining or sealing every 2 to 3 years at <strong>$3 to $7 per square foot<\/strong> in materials and labor. Composite needs only an annual soap-and-water wash. Over 20 years, the total cost of ownership lands within 10 to 15% of each other on a typical 400 sq ft deck.

A composite deck with deep gouges or surface fading is a replacement, not a refinish.<\/li>\n<li><strong>You are in a freeze-thaw zone with road salt splash.<\/strong> Northern US and Canadian decks take road salt in winter. Wood tolerates salt well if hosed off in spring; composite can pit at the salt line and the damage is permanent.<\/li>\n<li><strong>You want a specific color or grain pattern.<\/strong> Real wood grain is unique to every board. Composite is consistent, but the pattern repeats every 4 to 6 feet and is visible up close.<\/li>\n<li><strong>You want to DIY the install.<\/strong> Wood cuts with any saw, fastens with deck screws or hidden clips, and forgives small measurement errors. Composite requires specific hidden-clip systems, gapped end cuts, and manufacturer-matched fasteners.<\/li>\n<li><strong>Your budget is the constraint.<\/strong> For a 400 sq ft deck, the installed price gap between wood and composite is <strong>$4,000 to $8,000<\/strong>. That is the cost of a kitchen appliance, a roof section, or two years of property tax in many US markets.<\/li>\n<\/ul>\n<p>The standard detail for wood: <strong>pressure-treated southern yellow pine (SYP) #2 or better<\/strong>, 5\/4&#8243; x 6&#8243; decking boards, kiln-dried after treatment (KDAT) to reduce shrinkage, fastened with coated deck screws or stainless hidden clips. Cedar and tropical hardwood (ipe, cumaru) are premium upgrades at $25 to $45 per square foot installed and last 25+ years with the same maintenance cycle.<\/p>\n<h2>Where Composite Wins<\/h2>\n<p>Composite is the right pick when any of the following applies:<\/p>\n<ul>\n<li><strong>You will not maintain the deck.<\/strong> Be honest. A wood deck that is not sealed every 2 to 3 years turns gray, splinters, and loses 5 to 10 years of life. If you know you will not seal it, composite is the cheaper long-term call.<\/li>\n<li><strong>You have a pool or hot tub.<\/strong> Bare feet on splintered wood is a safety issue. Capped composite (Trex Transcend, TimberTech Azek, Fiberon Paramount) has a built-in slip-resistant texture that stays consistent for the deck&#8217;s life.<\/li>\n<li><strong>You want a single color that holds.<\/strong> Wood fades to gray in 6 to 18 months without seal. Composite fades 5 to 10% in the first 3 months and then holds. For dark colors (espresso, walnut), this is a real difference in curb appeal.<\/li>\n<li><strong>You have pets or kids who drag grit.<\/strong> Composite resists scratching and staining from pet nails, patio furniture, and BBQ grease far better than wood. Wine, grease, and leaf tannins wash off composite with soap; on wood, they leave a permanent stain unless sealed.<\/li>\n<li><strong>You are in coastal California, Florida, or anywhere with high UV and humidity.<\/strong> Composite handles UV and humidity cycles without warping, cupping, or checking. Wood in those climates needs constant sealing.<\/li>\n<\/ul>\n<p>The standard detail for composite: <strong>capped composite from a major line (Trex, TimberTech, Fiberon, MoistureShield)<\/strong>, 5\/4&#8243; x 6&#8243; grooved-edge boards with manufacturer-matched hidden clips, end caps on every cut, and gapping per spec (typically 1\/8&#8243; side, 1\/8&#8243; end). Avoid builder-grade uncapped composite (first-generation products from the late 1990s and early 2000s); they fade, stain, and mildew.<\/p>\n<h2>Side-by-Side: What 20 Years Looks Like<\/h2>\n<p>Here is the realistic 20-year cost breakdown for a 400 sq ft deck in climate zone 5 (typical US Midwest or Northeast):<\/p>\n<ul>\n<li><strong>Wood (pressure-treated pine, DIY sealing):<\/strong> install $7,000, sealing every 2 to 3 years at $400 to $600 per pass (DIY materials), total over 20 years: <strong>$11,000 to $13,000<\/strong>. Refinish sand at year 12 adds another $1,500.<\/li>\n<li><strong>Wood (pressure-treated pine, pro sealing):<\/strong> install $7,000, sealing every 2 to 3 years at $1,500 to $2,500 per pass (pro labor + materials), total over 20 years: <strong>$17,000 to $23,000<\/strong>. Refinish at year 12 adds $3,000.<\/li>\n<li><strong>Composite (mid-range line, DIY install):<\/strong> install $12,000 (materials $7,500 + DIY labor $4,500 hidden in weekend time), annual wash $40 in soap and water, total over 20 years: <strong>$13,000<\/strong>. No refinish.<\/li>\n<li><strong>Composite (premium line, pro install):<\/strong> install $16,000, annual wash $80, total over 20 years: <strong>$17,500<\/strong>. No refinish.<\/li>\n<\/ul>\n<p>The crossover point lands around year 8 to 12 for DIY-maintained wood, year 4 to 6 for pro-maintained wood. After crossover, composite is cheaper. The question is whether you can maintain the wood on schedule ,  most homeowners cannot, which is why composite now holds about 50% of the US deck market.<\/p>\n<h2>When to Call a Pro<\/h2>\n<p>Call a licensed deck builder if any of the following applies, because the fix is structural, not material:<\/p>\n<ul>\n<li><strong>Existing deck frame is more than 15 years old.<\/strong> The frame (posts, beams, joists) may be the limiting factor, not the decking. Reframing with pressure-treated lumber and adding composite on top is the standard retrofit.<\/li>\n<li><strong>Ledger board (where deck meets house) is failing or not flashed.<\/strong> This is the number-one cause of deck collapse in the US. The ledger must be bolted (not nailed) to the house rim joist with 1\/2&#8243; lag screws or through-bolts, and flashed with metal or PVC tape.<\/li>\n<li><strong>Soil is expansive clay or fill.<\/strong> Footings must be below the frost line (12 to 48 inches depending on US zone, 48 to 72 inches in Canadian zones). This is a code requirement and a structural call, not a material choice.<\/li>\n<li><strong>You want a multi-level deck or a roof over the deck.<\/strong> Both involve load calculations that need a structural engineer or an experienced deck builder. The material is the smallest part of the cost.<\/li>\n<\/ul>\n<h2>The Bottom Line<\/h2>\n<p><strong>Pick wood<\/strong> if your budget is the constraint, you are willing to seal every 2 to 3 years, and you want the option to refinish the deck in 10 years. Use pressure-treated pine for budget builds, cedar for a 25-year deck with the same maintenance, or ipe for a 30-year premium deck.<\/p>\n<p><strong>Pick composite<\/strong> if you will not maintain the deck, you have a pool or coastal exposure, or you want a single dark color that holds. Stick to capped composite from a major manufacturer (Trex, TimberTech, Fiberon, MoistureShield, Azek) and avoid first-generation products.<\/p>\n<p>For most US homeowners in 2026, composite is the right call by total cost of ownership ,  but only if you actually would not have maintained the wood. If you are the type who will seal the deck on schedule, wood is the better 20-year value, and the deck will look better at year 15 than composite at year 15.<\/p>\n<p><strong>For related comparisons, see<\/strong> <a href=\"https:\/\/www.skala8.com\/blog\/wood-vs-engineered-siding\/\">Wood vs Engineered Siding<\/a> <strong>and<\/strong> <a href=\"https:\/\/www.skala8.com\/blog\/asphalt-vs-metal-vs-tile-roofing\/\">Asphalt vs Metal vs Tile Roofing<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Composite and wood decking cost about the same over 20 years, but the year-by-year trade-off is sharp.
