The most vulnerable portion of trim is where it abuts a horizontal plane, in this case at the door threshold. This is why I always probe the base of door jamb trim for “soft spots.” This deteriorated door jamb was noted at a recent home inspection in Anacortes on Fidalgo Island. Keeping the base of these vulnerable elements well sealed (painted and caulked) will help safeguard against deterioration. It’s all about maintenance!
