Understanding Window Frame Rot
Wood rot around windows is a common issue in many homes, especially older ones. It’s typically caused by moisture infiltration and can compromise the window’s structural integrity if left untreated. Before deciding to replace the wood, it’s important to assess the extent of the damage.
When to Consider Wood Replacement
If the rot affects more than 10% of the frame or has spread to the surrounding structure, replacement is often the best option. Minor rot can sometimes be repaired with wood filler and epoxy, but extensive damage usually requires more comprehensive action.
Steps to Replace Rotted Wood Around a Window
1. Remove the rotted wood: Use a prybar, hammer, and chisel to carefully extract the damaged sections. Be cautious not to damage the surrounding healthy wood or the window itself.
2. Clean and prepare the area: Remove any debris and ensure the surface is clean and dry before proceeding.
3. Measure and cut replacement wood: Use weather-resistant wood like cedar or treated lumber. Cut it to fit precisely in the space where the rotted wood was removed.
4. Apply wood preservative: Treat the new wood with a preservative to protect against future rot and moisture damage.
5. Install the new wood: Secure the replacement pieces using appropriate fasteners and wood glue for a strong bond.
6. Seal and paint: Once installed, seal all joints and paint the new wood to match the existing frame and protect it from the elements.

Professional vs. DIY Replacement
While replacing rotted wood around a window can be a DIY project for those with carpentry skills, it’s often best to consult a professional. They can ensure proper installation and identify any underlying issues that may have caused the rot in the first place.
