A deck in Brentwood, TN will typically run you somewhere between $9,000 and $38,000+, depending on the size, the material you choose, and how complex the build gets.
That’s a wide range, and for good reason. A 12×12 pressure-treated deck is a very different project from a multi-level composite build with aluminum railings and integrated lighting.
If you want to know what you’ll actually pay, and what drives that number up or down, this guide covers all of it: materials, labor, deck size, permits, and more.
What’s the Average Deck Cost in Brentwood, Tennessee?
The average cost to build a deck nationally runs $30 to $60 per square foot, all-in, including materials and labor. In a market like Brentwood, expect to land in the upper half of that range or above it, depending on your choices.
For a realistic anchor, a 12×12 pressure-treated deck in the Nashville and Brentwood area typically costs between $9,000 and $15,000, with composite landing toward the top of that range.
Composite builds add significantly to those numbers. A premium composite deck at ProDeck Nashville, for example, has been quoted at $38,000 for a full build with Deckorators Voyage decking, aluminum handrails, hidden fasteners, and waterproof joist tape.
The material and feature choices make a bigger difference than square footage alone.
Deck Material Costs: Wood vs. Composite
The single biggest decision you’ll make, and the one that shapes your budget more than anything else, is your decking material.
Pressure-Treated Wood
Pressure-treated pine is the most common starting point for homeowners who want a solid, functional deck without spending a fortune up front.
Pressure-treated decking costs $25 to $50 per square foot installed, and sellers chemically treat pressure-treated pine to protect it from weather damage, rotting, and pests.
The tradeoff? You’re committing to regular maintenance. Staining and sealing every year or two is non-negotiable if you want it to hold up over time. Without that upkeep, the wood will start to warp and crack faster than you’d like. With proper care, a PT deck can last 15 to 20 years.
Composite Decking
Composite decking is a manufactured product designed to withstand Tennessee weather without demanding much of you in return.
Most traditional composite boards combine recycled wood fiber and plastic, though premium lines like Deckorators Voyage use a mineral-based composite technology, making them denser, stronger, and more moisture-resistant than standard composite boards.
Composite decking costs $40 to $80 per square foot installed, and it resists cracking and UV damage, so it doesn’t require resealing annually.
Premium brands, including the Deckorators Voyage, carry a 50-year structural warranty. It’s a higher upfront investment, but maintenance costs over the life of the deck are substantially lower.
Cedar
Cedar decking costs $30 to $47 per square foot installed, and cedar wood naturally resists weather damage and pests, eliminating the need for chemical treatments.
It’s a middle-ground option, priced between pressure-treated and composite, with a natural look that many homeowners prefer.
Annual resealing is still recommended to protect against moisture, but it handles the elements better than pine without the chemical treatment.
Labor Costs for Deck Building in Brentwood
Labor costs typically range from $15 to $35 per square foot, and factors affecting cost include size, materials, and design complexity.
Simpler builds with straightforward layouts land at the lower end. Multi-level decks, complex rooflines, or second-story builds significantly increase labor costs.
What professional labor usually covers:
- Site prep and post-hole digging
- Framing and structural work
- Decking surface installation
- Railing and stair construction
- Cleanup and debris removal
A contractor who handles permits, design, and build as a complete package gives you a cleaner experience than sourcing each piece separately. That’s worth factoring into your comparison when you’re getting quotes.
5 Factors That Affect the Total Project Cost
Size is the obvious driver, but several other variables can shift your final number considerably.
- Deck height — A second-story deck requires more structural engineering and additional labor compared to a ground-level build. Budget accordingly.
- Stairs — Each staircase adds to the total. A wide staircase with railings can add several thousand dollars.
- Railing type — Basic wood railings are the most affordable option. Aluminum railings, like Fortress Fe26 used by higher-end builders in the area, cost more upfront but are far more durable and require almost no ongoing maintenance.
- Existing deck removal — Demolishing and removing an old deck costs $5 to $15 per square foot. If you have a deck that needs to come down first, include it in your budget early.
- Permits — A deck permit costs between $230 and $500, depending on your location. In Brentwood, deck permits are issued by the City of Brentwood’s Planning & Codes Department. Most reputable contractors handle this for you before breaking ground.
Does a Deck Add Value to Your Brentwood Home?
Yes, adding a deck can provide a return on investment of up to 80%. In a market like Brentwood, where outdoor living space is genuinely valued by buyers, that ROI carries real weight.
Composite decks tend to hold their value better over time, partly because buyers know they won’t be inheriting a maintenance project.
FAQ: Deck Cost in Brentwood, Tennessee
How much does a 12×12 deck cost in Brentwood, TN?
A 12×12 deck, 144 square feet, typically runs between $9,000 and $15,000 in the Brentwood area. Pressure-treated wood sits at the lower end of that range, with composite toward the top. Railings, stairs, and old deck removal all push the number higher.
Is composite decking worth the extra cost?
For most Brentwood homeowners, yes. The upfront price is higher, but composite decks don’t need to be stained or sealed every year. Over a 10 to 15-year window, the saved maintenance time and material costs often offset the price difference.
Do I need a permit to build a deck in Brentwood, TN?
Yes. The City of Brentwood requires a building permit for decks. Any licensed contractor should be pulling that permit before construction starts.
How long does it take to build a deck in Brentwood?
Most standard decks take around 3-5 days, start to finish. The concrete footings need time to cure, which accounts for most of the timeline. A smaller 12×12 deck can sometimes wrap up in a single day once footings are set and cured.
What’s the cheapest type of deck to build?
Pressure-treated pine is the most affordable option. For a smaller deck in the 12×12 to 16×20 range, it’s possible to come in at the lower end of the pricing ranges above. Keep in mind that lower upfront material costs usually translate into more maintenance spending year after year.
How do I find a reliable deck contractor in Brentwood?
Ask for references, check Google reviews, and make sure the contractor is licensed and insured. Look for someone who pulls permits, offers a clear contract, and backs their work with a warranty.
