**Step-by-Step Guide to Replacing a Rotten Window Sill**
**Step 1: Assess the Damage**
- **Inspect the Window Sill**: Determine the extent of the rot. If the rot has spread to the frame or surrounding structure, you may need professional assistance.
- **Safety First**: Wear gloves and safety glasses to protect yourself from splinters and debris.
**Step 2: Remove the Rotten Window Sill**
- **Remove Window Trim (If Necessary)**: Carefully remove any trim or molding around the window sill using a pry bar and hammer.
- **Cut Through Caulk and Paint**: Use a utility knife to slice through any caulk or paint sealing the sill to the window frame.
- **Detach the Sill**: Use a pry bar and chisel to gently lift and remove the rotten sill. Be cautious not to damage the window frame or wall.
- **Clean the Area**: Remove any remaining debris, nails, or screws from the window opening.
**Step 3: Prepare the New Window Sill**
- **Measure the Opening**: Accurately measure the length, width, and thickness of the original sill.
- **Cut the New Sill**: Using your measurements, cut the replacement sill to size with a saw.
- **Test Fit**: Place the new sill into the opening to ensure it fits properly. Make adjustments as needed.
- **Pre-Drill Holes**: To prevent splitting, pre-drill holes for the screws or nails that will secure the sill.
**Step 4: Install the New Window Sill**
- **Apply Wood Glue**: For added stability, apply wood glue to the areas where the sill will contact the frame.
- **Position the Sill**: Place the new sill into the window frame, ensuring it is level and properly aligned.
- **Secure the Sill**: Fasten the sill using galvanized screws or nails through the pre-drilled holes.
- **Reattach Trim**: Replace any trim or molding that was removed, securing it with finishing nails.
**Step 5: Seal and Finish**
- **Fill Gaps and Holes**: Use wood filler or epoxy to fill any gaps, screw holes, or imperfections.
- **Sand the Surface**: Once the filler has dried, sand the sill and surrounding areas until smooth.
- **Apply Caulk**: Seal all joints and edges with exterior-grade caulk to prevent moisture infiltration.
- **Prime and Paint**: Apply a coat of primer followed by exterior paint or stain to protect the wood and match your home's aesthetics.
