Today I was reminded of how things can change at a home from day to day. We visited an almost new home built in 2004 and the rear yard had a large wood deck with a sun room screened porch on one end. The decking planks at the top of the stairs had cupped at the end of a couple of boards, pulling the nails free of the 2×10 joists and curving up 6” leaving hand size holes, trip hazards if not noticed. My client was amazed, he stated that he had visited the home just 2 days prior and it had looked fine. Wood decks are made of pressure treated lumber and when left in the GA sun with out sun block or UV stain will weather and split, in this case drying from recent heavy rains and warping. Water seal and maintain all outside wood walks, decks and landings, to extend the life of your home and prevent added maintenance.
