Pennsylvania Climate and Deck Maintenance

The Philadelphia area experiences 25-35 freeze-thaw cycles per winter. Each cycle pushes moisture into the wood grain and then expands it as it freezes — gradually breaking down the finish and the wood fibers underneath. A well-maintained deck with a quality stain applied every 3-4 years will outlast an unmaintained deck by decades.
