How to spot dry rot before it spreads

Dry rot usually begins when wood stays damp long enough for decay to take hold. On Woodinville homes, the first warning signs often show up around trim boards, deck ledgers, siding edges, window corners, stair stringers, and shaded exterior elevations. A board may look intact from several feet away but feel soft when pressed, crack under paint, or crumble when probed. The most important step is not just identifying the damaged board — it is understanding where the water came from. Check gutters, deck transitions, siding seams, flashing, and areas where moss or debris hold moisture. If you find repeated staining or softness in one area, schedule a dry rot inspection before the decay spreads into framing or sheathing.
