Wood rot repair replaces or rebuilds wood damaged by moisture before it gets painted. Rotted wood won’t hold paint or hold up structurally, and painting over decay only hides the problem while it spreads. Knowing this, we always address the damage first so the new finish has solid wood underneath.
Rot rarely stops where you can see it. Probing affected areas before repair determines how far the damage runs, and replacing enough sound wood around it keeps the rot from resuming under the new coat.
