Prices from 8 Georgia deck builders
This is a typical range, not a quote. The sections below explain what moves the price for this job. The dot marks the middle price, and a + means some businesses charge more.
What the job involves
A composite deck is built like any other deck below the surface: footings, posts, beams and joists, usually of pressure-treated lumber. The difference is on top, where the boards are a blend of wood fibers and plastic, and the stair treads, fascia and railings are often composite or metal to go with them.
The boards are not stained or sealed. They usually need washing to stay clean, and depending on the line, some can scratch or fade in strong sun. PVC boards, made with no wood fiber at all, are a related choice that some builders also offer at a different price.
The wood deck page covers the same project with wood boards on top, and the new deck range is for decks where the estimate did not name a material.
What moves the price
- Capped or uncapped boards
- Boards wrapped in a protective outer shell usually cost more than uncapped composite and resist stains and fading better. Ask whether the boards in the quote are capped.
- Waste on patterns
- Diagonal boards or a border around the edge mean more cuts and more leftover pieces, and at composite prices that waste raises the bill.
- Heat and color
- Darker composite boards can get hot underfoot in summer sun. Lighter colors run cooler, and some lines price their colors differently.
- Railing system
- Composite and aluminum railing kits are often priced by the section, and glass panels or cable cost more than standard balusters.
- Airflow under low decks
- Some board makers call for open space under the boards for air to move. A deck built close to the ground may need framing changes to allow it, which adds cost.
Getting a quote
Questions to ask each deck builder before you compare prices:
- Are the boards capped, and which grade or color line is this price for?
- Is the frame pressure-treated wood, and what joist spacing will you use for these boards?
- Are the stair treads, fascia and railings composite too, or wood?
- Will you use hidden fasteners, or screws through the top of the boards?
- How should I clean these boards, and what would void the board maker's warranty?
