Composite decking costs more upfront than pressure-treated wood but requires far less maintenance and typically lasts 25-30 years, making it the better long-term value for most homeowners.
Pressure-Treated Wood
Pressure-treated lumber is the most budget-friendly decking option and remains a solid choice for homeowners who plan to keep up with regular maintenance. It requires staining or sealing every 1-2 years to prevent warping, splintering and rot, and typically lasts 10-15 years with consistent care.
Composite Decking
Composite decking, made from a blend of wood fibers and recycled plastic, costs more upfront but needs no staining or sealing. It resists fading, staining, warping and splintering, and typically comes with warranties of 25-30 years. Brands like Trex, TimberTech and Azek each offer several tiers, from more affordable capped composite to premium PVC boards.
Comparing Long-Term Cost
While composite costs more to install, the maintenance savings over a 20-25 year span often make it the more economical choice overall, especially when you factor in the labor or product cost of staining wood every year or two.
Other Considerations
Beyond material, think about railing style, whether you want a covered or open deck, and how the deck integrates with your home's existing exterior. A well-planned deck also accounts for proper footings, ledger board flashing to prevent water damage to the house, and code-compliant railing height and spacing.
