Quick Answer
In 2026, a deck in Farragut and West Knoxville runs $15,000 to $30,000 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.
- VistaFi financing keeps a deck to a monthly payment with no home equity required.

It costs more upfront but lasts 25+ years with almost no maintenance, while wood needs sealing every year in our humidity or it rots and grays.
A deck in Farragut or West Knoxville runs $15,000 to $30,000 for a small composite deck, $35,000 to $60,000 for a mid-size or elevated deck, and $60,000 to $150,000 or more for a large, multi-level, or covered build.

What Drives the Price?
- Size and height. Bigger decks need more material. Taller decks need more structure: bigger posts, deeper footings, more bracing, and longer stairs. A second-story walkout deck costs more than the same square footage near the ground.
- Material. Pressure-treated wood is cheapest upfront. Composite (we build with Trex and 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 balusters, and on an elevated deck there is a lot of railing. See deck railing options and cost.
- Stairs. A long run of stairs down a slope is real carpentry and real money.
- A roof or a second level. Covered sections and tiers add cost, and they add living space. We cover both in are covered decks worth it and multi-level decks.
- Extras. Lighting, built-in benches, and under-deck drainage for a dry space below all add to the total.
Why Do West Knoxville Lots Change the Number?
A lot of homes in Farragut, Hardin Valley, and along Northshore sit on a slope with a walkout basement. That usually means an elevated deck off the main floor instead of a low platform. Height is the biggest reason two decks of the same size get very different quotes.
Sloped yards also raise the question of what goes underneath. Some homeowners add a paver patio below the deck, or under-deck drainage so the lower level stays dry. If you are weighing the two, deck vs. patio walks through which fits which yard.
Why Does Material Matter More in Our Climate?
East Tennessee humidity and freeze-thaw punish the wrong decking. Wood needs sealing every year or it rots and grays. Composite shrugs it off. For most Farragut and West Knoxville homeowners, composite is the best long-term value. You build it once and spend weekends on it, not maintaining it.
If you want the numbers on upkeep, see what a wood deck costs to maintain. Then explore our composite deck options.
Do You Need a Permit or HOA Approval?
Plan on it. Decks generally need a building permit in our area, and the Town of Farragut and Knox County each run their own review. Many West Knoxville neighborhoods also have an HOA or architectural committee that wants to see the plan first. Rules and thresholds vary, so confirm with your local building office and your HOA before work starts. Our post on permits for decks, patios, and pergolas covers the basics, and our permits and HOA approval page explains how we handle it.
Should You Repair the Old Deck or Replace It?
If you already have a deck, the framing decides it. Sound framing can sometimes take new boards and railing. Framing that is soft, sagging, or pulling away from the house means starting over. See deck repair vs. replace and our deck renovation page.
What About Financing?
VistaFi financing keeps a deck to a comfortable monthly payment with no home equity required.
