Composite decking has become the standard in Charlotte's climate—wood decks require significant maintenance in the humidity and sun. A 300 sq ft composite deck typically runs $15,000-$25,000 installed. Patios using pavers or stamped concrete offer lower-maintenance alternatives, typically at $12,000-$30,000 for a similar area. Charlotte's expansive clay soil means proper drainage and base preparation are critical for patios.
Charlotte's clay is the deciding variable for patios. Expansive soil heaves and settles with moisture cycles, so a paver patio without a properly compacted aggregate base and edge restraint will telegraph its failure within two or three seasons. Base preparation is the line item to protect when quotes come in over budget.
For decks, the humidity and UV load make the composite-versus-wood decision mostly economic. Pressure-treated framing under a composite surface is standard here; the surface material is what buyers see and what avoids annual sanding and sealing that few owners actually keep up.
Drainage is the failure mode nobody quotes. Water shed from a new deck or patio has to go somewhere, and in tight Charlotte lots that often means a French drain or regrading. Ask each bidder to explain, on paper, where the water goes.
