How much does a deck cost in Springfield, MO?

A typical mid-size deck runs in the tens of thousands, and composite costs more than pressure-treated wood. Here's the best public data, and what makes your quote different.

Benchmark: 16×20 ft deck, U.S. national average, 2025	Average job cost	≈ per sq ft
Pressure-treated wood decking, PT frame, railing, stairs	$18,263	≈ $57
Composite decking, PT frame, railing, stairs	$25,096	≈ $78

Source: Remodeling magazine / Zonda, 2025 Cost vs. Value Report, national averages. The report doesn't publish a Springfield-specific figure, so treat this as a starting point; local labor costs differ. Per-sq-ft is our arithmetic (cost ÷ 320 sq ft). Not a quote.

Rough ranges by project (our estimates)

These ranges are our estimates, scaled from the national benchmark. For budgeting only; real quotes depend on your site.

Project	Estimated range
Small low deck or landing (~100–150 sq ft), pressure-treated	$5,000–$10,000
Mid-size deck (~300–350 sq ft), pressure-treated	$15,000–$23,000
Mid-size deck (~300–350 sq ft), composite	$21,000–$30,000
Large, elevated or multi-level, composite/PVC with upgraded railings	$35,000–$60,000+
Resurfacing (new boards and railings on a sound frame)	Often well under a full rebuild, if the frame passes inspection

What pushes the price up

Hillside lots: Ozarks slopes and walk-outs mean tall posts, bracing, multi-level designs and long stair runs.
Footings: Springfield lists a 24-inch frost depth, and rocky Ozarks ground can slow digging.
Covered decks and screened porches for summer shade and bugs add framing and roofing.
Decking and railings: PVC and premium composite cost more than PT; aluminum, cable and glass railings vary widely.
Shape and extras: angles, multiple levels, built-in benches, lighting and roofs add labor.
Demolition of an old deck, and permits and plans.

How to compare quotes

Make sure each quote has the same size, material, railing and stair count.
Ask who pulls the permit and whether fees are included.
Ask how the ledger is attached and flashed, and what connectors are used.
Missouri has no statewide general contractor license, so ask your city's building office (Springfield: Building Development Services) what applies, and always ask for insurance and a written contract.
Avoid paying most of the price up front.
