Quick Answer
In 2026, a deck in Farragut and West Knoxville runs $15,000 to $25,000 for a small deck under about 300 square feet, $35,000 to $60,000 for a mid-size deck around 300 to 600 square feet, and $60,000 to $150,000+ for a large, multi-level, or covered build.
- Price is driven by size and height, material choice, railing type, and whether the deck is covered or multi-level.
- Pressure-treated wood is the cheapest material upfront; composite (Trex, TimberTech) costs more but lasts 25+ years with almost no maintenance; aluminum is the premium, do-it-once option.
- East Tennessee humidity and freeze-thaw punish the wrong decking: wood needs sealing every year or it rots and grays, while composite shrugs it off.
- Most homeowners finance a deck rather than pay cash, and VistaFi financing keeps it to a monthly payment with no home equity required.

What Drives the Price
- Size and height. Bigger and taller decks need more material and more structural support.
- Material. Pressure-treated wood is cheapest upfront; composite (Trex, TimberTech) costs more but lasts 25+ years with almost no maintenance; aluminum is the premium, do-it-once option. We break this down in composite vs. wood vs. aluminum.
- Railings. Cable, aluminum, and glass railings cost more than standard.
- Covered or multi-level. Roofs, stairs, and tiers add real cost, and real living space.
