What does fixing this actually cost?** A: About $375 a sill rebuilt in real wood — roughly $1,100 for all three, profile-matched and primed. Fix it before the appraisal and the $8,000 conversation disappears from the table entirely. **Q: A handyman quoted wood filler and paint for $150. The window company quoted $2,800 for a replacement. Who's right?** A: Neither. Filler over rot fails in a season — it traps moisture and the soft spot spreads under the paint. A new window for a rotted sill is a new car for a flat tire. Cut the decay out, rebuild in wood, correct the water: from $375. **Q: There are wasps crawling into the rotted corner of my window frame. Pest problem or wood problem?** A: Wood problem wearing a pest costume. Wasps move into soft, hollowed wood because it digs easily. Rebuild the wood from $375 and the doorway closes for good — no monthly spray subscription required. **Q: The paint keeps bubbling on one sill no matter how often we repaint. Why?** A: Because the water is coming from behind the paint — a failed caulk joint or drip edge feeding the wood. Repainting seals moisture in. Fix the source, rebuild the wet wood, then the paint finally holds. **Q: Where do you work?** A: Wherever the coverage below reaches — rotten-wood city pages carry the local detail. ## Serving NC & Surrounding Areas Our milling bench serves every city below — find yours for the local page.
