A good, long-lasting solution is to replace the wood jamb, brick mold trim and doorstop with paintable solid vinyl pieces that won’t crack or decay. Available at home centers and lumberyards, the three pieces cost a total of about $4 per ft.—comparable to clear wood. The vinyl can be cut, nailed and painted just like wood. It’s available in white, but you can order brown, bronze and tan. Fill nail holes with white caulk or exterior wood filler, then if desired prime and paint with acrylic latex. Use a light paint color over white vinyl to keep it from overheating.
