Leander Deck Cost, Worked Out Line by Line
On October 31, 2026, the parts for a 12x16 treated wood deck cost $1,289.48 at the Leander Home Depot. Add crew pay and the $135 permit, and you have the floor under any fair quote.
The Sample Deck
To keep the math honest, we priced one plain deck. It runs 16 feet along the back of the house and 12 feet out into the yard. One side bolts to the house. The other side rests on a beam and 4 posts. Joists are 2x8s set 16 inches apart.
It sits low, under 30 inches, so no rail is needed by code. Many Leander lots slope, so your deck may stand taller. Treat this as a starting point.

Wood or Composite
The frame stays the same no matter what you walk on. The top boards are where the money moves.
| Deck Top | Whole Deck |

| Treated pine boards | $1,289.48 |
| Trex Enhance Basics, 27 at $31.98, plus a $154 bucket of hidden clips | $1,934.88 |

| Rail add on, 6 treated rail kits at $57.98 and 4 posts at $10.68 | $390.60 |
TimberTech boards showed no shelf price at the Leander area stores on the day we checked, so they are not in the table. More on board types on our decks page.
Crew Pay
The Bureau of Labor Statistics surveys pay in the Austin, Round Rock and San Marcos metro. These are its May 2025 numbers.
| Worker or Crew | Pay |
|---|---|
| Carpenter, median | $24.16 per hour |
| Carpenter, 25th percentile | $23.05 per hour |
| Carpenter, 75th percentile | $28.01 per hour |
| Construction laborer, median | $21.16 per hour |
| Crew day, 1 carpenter and 1 laborer, 8 hours | $362.56 |
| 4 crew days | $1,450.24 |
| 6 crew days | $2,175.36 |
| 8 crew days | $2,900.48 |
The day counts are wage math, not a quote. How long a deck takes depends on the slope, the rock and the stairs. We can tell you after we walk the yard.
The Permit
Inside city limits, a 12x16 deck permit comes to $135 on the city fee list. That is a $50 application, $20 plan review, the $40 minimum building permit and a $25 technology fee. Each reinspection is $100, so it pays to pass the first time. Our Leander permit guide has every step.
Low, Middle and High
Each line adds three things. The parts, the crew pay and the permit. Totals are rounded to the dollar.
| 12x16 Deck | Parts, Pay and Permit |
|---|---|
| Low. Treated boards, no rail, 4 crew days, $135 permit | $2,875 |
| Middle. Trex Basics, rail, 6 crew days, $135 permit | $4,636 |
| High. Trex Naturals, rail, 8 crew days, $135 permit | $5,508 |
The low line is $1,289.48 plus $1,450.24 plus $135. The middle line is $1,934.88 plus $390.60 plus $2,175.36 plus $135. The high line is $2,081.76 plus $390.60 plus $2,900.48 plus $135.
Why Quotes Run Higher
No builder can work at the numbers above. A real business also pays for insurance, a truck, fuel, saws, blades and the scrap pile. It pays someone to draw the plans and upload them. And it has to earn a profit to stay open.
So expect a fair quote to sit well above the table. What matters is that you can read it. Ask for parts, labor and the permit on separate lines. Then line it up against this page. The questions on our how to hire list help too.
What Adds Cost Here
- Slope. A yard that falls away needs taller posts, bracing and a rail once the deck is 30 inches up.
- More levels. Each one adds posts, beams and steps. The city lists multi level decks by name. See multi level decks.
- A roof. A covered deck adds posts, rafters and roofing. See covered decks.
- Stairs and landings. Every step down to the yard costs wood and time.
- Rock. Post holes cut into rock take longer.
- Oaks. Building around roots takes care. Plan limb work outside February 1 through June 30.
- An old deck to tear out and haul off.
How We Got These Numbers
- We drew the sample deck and counted each board, post, hanger and box of screws.
- We priced each part at the Leander Home Depot on October 31, 2026, and checked five more Austin area stores.
- We used the May 2025 BLS median pay for carpenters and construction laborers in the Austin metro.
- One carpenter plus one laborer for 8 hours made one crew day.
- We took the permit fee from the city fee list, updated October 2, 2025.
