Exterior wood rot

Answer: call a carpenter.

Soft, crumbling, or discolored wood on exterior trim, window frames, door frames, or siding signals wood rot — a fungal decay that spreads when wood stays moist. Left untreated, rot compromises structural integrity and invites insects like carpenter ants and termites. Small areas can be repaired with epoxy wood filler, but large sections require cutting out the damaged wood and splicing in new material. A carpenter can assess the extent of the damage, determine whether it's cosmetic or structural, and perform lasting repairs with rot-resistant materials.
