Lorne & Linda found the Everlast door to be a perfect crawlspace entrance solution. EverLast crawlspace doors are made from ½-in.-thick PVC plastic that is just about indestructible. Unlike wood crawl space doors, EverLast doors will never warp, crack, shrink or require maintenance or painting. An air and water seal are certain, thanks to the heavy-duty weather stripping that comes with each EverLast door.
