How Allentown's Climate Affects Deck & Patio
In Allentown's freeze-thaw climate, composite decking is the strongly preferred choice over pressure-treated wood. Wood absorbs moisture and expands and contracts with each freeze-thaw cycle, accelerating splits, cupping, and fastener pullout within 5–8 years. Quality composite maintains its shape through extreme temperature swings and eliminates the annual sealing requirement.
