Window frame rotting? Dit is wie je moet bellen

Rotting window frames let moisture, air, and pests into your home while driving up energy costs. Left untreated, rot spreads from the frame into the wall framing behind it, turning a $300–$800 repair into a $2,000+ structural job. A carpenter can assess the extent of damage and either repair the affected wood or replace the frame entirely.
