Cost is the first question almost everyone asks, and it's also where a lot of sites either dodge the number entirely or give you one figure that doesn't hold up once your actual project gets quoted. Here's the real range, broken down by size and material, plus what actually moves the number up or down on your specific lot.

Note: the figures below are current national/regional market data for 2026, not a Springfield-specific price study (no such local dataset exists publicly). Treat them as an honest planning range, and confirm the final number against a written quote for your actual project.

Cost per square foot by material

MaterialCost per sq ft installedMaintenance
Pressure-treated pine$30-45Restain every 2-3 years
Cedar$30-50Periodic sealing, less often than PT
Composite (Trex, TimberTech, Fiberon, AZEK)$45-70Occasional washing only

Cost by common size

SizeSquare feetPressure-treatedComposite
10x12120 sq ft$3,600-$5,400$5,400-$8,400
12x16192 sq ft$5,760-$8,640$8,640-$13,440
16x20320 sq ft$9,600-$14,400$14,400-$22,400

These are material-and-labor installed ranges for a standard single-level deck with basic railing. Elevated decks, roof coverings, built-in seating, multilevel designs, and engineered footings for depths beyond 14 feet from the house all add cost beyond these baseline figures.


What actually moves the price on your lot


Does a deck pay for itself at resale?

Wood decks recoup most of their cost at resale, generally outperforming most kitchen or bathroom remodel dollar-for-dollar, according to national cost-versus-value industry data. Composite decks hold their resale value slightly better than wood in colder-climate regions specifically, since buyers in snow-and-freeze markets weigh the reduced maintenance more heavily. Exact recoup percentages vary by region and the report that tracks them requires a paid industry subscription to pin down precisely, so treat "most of the cost back, more than a typical remodel" as the honest takeaway rather than a specific percentage.


Costs that catch people off guard

A few line items that don't always make it into a first conversation about price but show up on the actual quote:


How to read a quote that seems too good

If one quote comes in well under the ranges above, ask specifically what footing depth they're planning, what hardware they're using (hot-dip galvanized or stainless, not standard zinc-coated), and whether the price includes pulling the permit. A quote that's cutting corners on any of those three is often how a builder gets to a lower number, and all three are the kind of shortcut that's invisible at completion and expensive years later.

The estimator on our home page gives you a starting range based on your size, material, and elevation. For a firm number, request a free quote, actual site conditions (soil, access, existing structure if you're replacing a deck) are what turn a range into a real price.


FAQ

Why is composite so much more expensive than pressure-treated?

Composite material itself costs more per board than pressure-treated pine, and it's manufactured to a tighter, more consistent spec. You're paying for that consistency and the reduced long-term maintenance, not for the same wood with a markup.

Is the cheapest quote usually the right choice?

Not automatically. A quote well below the ranges above is worth asking hard questions about, undersized footings, non-code hardware, and skipped permits are the usual ways a builder gets to a lower number, and all three cost more to fix later than they saved up front.

Do these prices include the permit fee?

No, permit fees are a separate line item and vary by jurisdiction. See our permit guide for the specifics by town.
