Composite vs. Wood Deck Cost in 2026: Which Saves More Long-Term?
Composite vs. Wood Deck: Cost, Maintenance & Value Compared (2026) Composite decking costs $30-$60 per square foot installed in 2026, roughly double the $15-$25/sq ft price of pressure-treated wood -- but composite's near-zero maintenance means it costs less over 20 years. For a standard 320 sq ft deck, pressure-treated wood totals about $16,000 over 20 years (including stain, seal, and board replacements), while composite holds at roughly $14,400. The crossover point where composite becomes cheaper is somewhere around year 12-14 for most projects. I have been framing and finishing decks across the mid-Atlantic for over fifteen years, and the composite-vs-wood conversation comes up on every single project. Last spring I built two nearly identical 16x20 decks three miles apart in northern Virginia -- one in Trex Transcend, one in pressure-treated southern pine. The PT deck cost $6,400 installed. The composite came to $13,800. On paper, the wood deck looks like...
How Much Does a Deck Cost in 2026? (National Averages & Real Pricing)
How Much Does a Deck Cost in 2026? The average deck costs $30 to $60 per square foot installed in 2026, with total projects ranging from $4,400 to $12,500 for a typical 200-400 square foot deck. Pressure-treated wood runs $15-$25/sq ft installed, composite decking costs $30-$60/sq ft, and premium PVC or hardwood reaches $45-$75/sq ft. Labor accounts for roughly 50-60% of total project cost. I priced out 14 deck projects in the mid-Atlantic last year, and the single biggest shock for homeowners was not the material cost -- it was the footing work. A 16x20 composite deck in suburban Virginia came to $14,200 installed, and $3,100 of that was excavation, concrete footings, and the structural frame that nobody sees. The decking boards that everyone obsesses over? About $3,800. The lesson: the stuff under the deck costs almost as much as the stuff on top of it.

How Much Does Deck Railing Cost in 2026? (By Material & Style)
How Much Does Deck Railing Cost in 2026? Deck railing costs $20 to $600 per linear foot installed in 2026, with the average homeowner spending approximately $2,500 for a standard deck perimeter. Wood railing is the most affordable at $20-$50/ft, composite and vinyl run $25-$60/ft, aluminum costs $50-$200/ft, cable railing runs $85-$180/ft, and glass panels reach $100-$600/ft. A typical 320 sq ft deck with railing on three sides (52 linear feet) costs $1,040-$10,400 depending on material. I installed deck railings on eleven projects in the greater Philadelphia area last year, and the cost gap between materials is wider than any other deck component. A 16x20 composite deck in suburban Bucks County had three identical bids for the decking at $12,000-$13,500. But the railing quotes ranged from $1,800 (aluminum baluster) to $9,200 (glass panel). The railing represented 13% of the project with aluminum and 41% with glass. Nothing else on a...
Average Deck Cost by State in 2026 (All 50 States Compared)
Average Deck Cost by State in 2026 (All 50 States Compared) The national average cost to build a 320 sq ft composite deck in 2026 is approximately $14,000, but actual costs range from $10,500 in Mississippi to over $19,000 in Hawaii depending on local labor rates, building codes, frost line depth, and material availability. High-cost coastal states like California, New York, and Massachusetts run 20-35% above the national average, while southern and rural states typically come in 15-25% below it. I have been building and estimating decks across the Mid-Atlantic for almost two decades, and one thing I can tell you with certainty is that the same 320 sq ft composite deck that costs $13,500 in suburban Maryland would run $17,500 or more in Fairfield County, Connecticut. The materials are identical. The labor is where the gap lives. When I help homeowners budget for a deck project, the first thing...
How to Build a Deck: Complete Materials & Cost Calculator Guide
How to Build a Deck: Complete Materials & Cost Calculator Guide Building a deck costs between $15 and $75 per square foot for materials, depending on whether you choose pressure-treated lumber, composite, or cedar. A typical 16x20 deck requires 50-60 deck boards, 20-25 joists, 8-12 posts, and roughly 15 pounds of structural screws and hardware. Getting the material quantities right before you order saves hundreds of dollars in waste and emergency trips to the lumber yard. Last year I built a 16x24 composite deck for a client in suburban Maryland. The material bill came to $8,200 -- and that was after negotiating a bulk discount on the composite boards. I ordered 15% extra decking and used every single piece, because cuts around the stair landing and the angled corner ate through boards faster than the calculator predicted. That project reinforced what I tell every homeowner: always round up, never down....
