Average Cost of a 20x20 Pressure-Treated Deck in Fayetteville AR
A 20x20 pressure-treated wood deck in Fayetteville AR — 400 square feet — typically costs between 0,000 and 8,000 fully installed in 2026. This range reflects differences in site conditions, elevation, railing style, stair configuration, and current lumber prices. At the lower end of the range, you are getting a ground-level or low-elevation deck with basic railing and a single stair run. At the higher end, you are looking at an elevated deck with a custom railing system, multiple stair sections, or a more complex design.

Several variables move the price of a pressure-treated deck up or down significantly. Elevation is the biggest — a deck that sits 8 feet off the ground requires substantially more structural material and labor than a ground-level build. Railing style is next — basic pressure-treated wood railings cost far less than cable rail or aluminum systems. Stair complexity, site access, and soil conditions also affect cost. JHG Contracting provides a fully detailed written estimate that breaks down every line item so you know exactly what you are paying for.
