How Much Does Deck Building Cost in Peachtree City, GA? (2026 Guide)
Deck pricing in south metro Atlanta comes down to three numbers: square footage, material, and how much structure sits under the walking surface. A ground-hugging pine deck off a slab is a different animal from a second-story composite deck on 10-foot 6x6 posts with a stair run and a hold-down at every guard post. Published Atlanta figures put installed pressure-treated pine decking in the high teens per square foot and installed composite in the low thirties for the boards and labor alone; a full built deck with framing, footings, guards and stairs runs higher than that. Here is how quotes usually break out around Fayette County.
| Service | Typical Peachtree City Range |
|---|---|
| Pressure-treated pine deck, built new (200-400 sq ft) | $26 - $42 per sq ft |
| Capped composite deck, built new (200-400 sq ft) | $48 - $80 per sq ft |
| Re-deck over sound existing framing | $22 - $40 per sq ft |
| Screened porch under a new roof (12x16 to 16x20) | $32,000 - $70,000 |
| Screening an existing covered deck or porch | $4,500 - $12,000 |
| Structural repair - ledger, joists, posts or footings | $1,800 - $9,000 |
| Pressure wash, sand and re-stain a wood deck | $2.50 - $5.50 per sq ft |
| Pergola, attached or freestanding (10x12 to 14x20) | $5,500 - $18,000 |
| Stair flight, 3 to 6 risers with rail | $1,400 - $3,600 |
| Cable or aluminum rail upgrade | $95 - $220 per linear ft |
| Peachtree City Tree Fund contribution, specimen tree removal | $20 per caliper inch DBH |
What Changes the Price?
Height off grade drives more cost than square footage does. A deck 18 inches off a walkout is framing and boards. Once the walking surface passes 30 inches above grade, guards become mandatory, every guard post needs a hold-down rated to 1,800 pounds, and post length, footing size and bracing all step up together.
Material choice is the second lever. Pine and capped composite frame identically but finish very differently, and composite adds joist-spacing rules, hidden fastener labor and a fascia detail that pine does not need.
Trees and access. If a specimen tree sits in the footprint, the removal, the permit and the $20 per caliper inch Tree Fund contribution all land in the budget, and a rear yard reachable only through a 36-inch gate adds labor to every stick that goes in.
What the ledger can attach to. A band joist on a sill plate is straightforward. Brick veneer, a cantilevered floor overhang or open-web floor trusses are all prohibited ledger substrates in Fayette County's deck guide, which means a freestanding frame on its own posts and beam - real money, and better found at the quote than at framing inspection.
Every quote is free, measured on site, and itemized so you can see the framing, the decking, the rails, the stairs and any tree or permit cost as separate lines. Nothing gets ordered before you approve the drawing. If the honest answer is that your existing frame is sound and you only need boards and rails, that is the quote you get - re-decking a good frame is one of the better values in this trade, and pretending otherwise is a short-term business.
