Choosing Doors That Stand Up to South Carolina Humidity

South Carolina humidity is hard on exterior doors. Summer heat pulls moisture into wood fibers, daily temperature swings make materials expand and contract, and coastal or inland dampness can expose weak points faster than many homeowners expect.
