The local climate will determine the best material for a deck. Pressure-treated pine hardwood, non-treated wood, composite, PVC, and vinyl are top decking material picks across all climates. Pressure-treated pine hardwood and vinyl are the cheapest options, at roughly $1.50 and $3 per square foot (psf) each. PVC and composite are more costly, at $4 and $5 psf. Non-treated wood runs from $4 psf for cedar, to $6 psf for redwood and $8 psf for ipe.
