What Are the Signs of Window Rotting?
There are many indicators that your window sills have a rot problem. The first one, of course, is visible signs.
Step 2: Remove the Rotted Areas
Using either a chisel or a wide screwdriver, remove the rotted wood from the windowsill gradually until you start to see ‘healthy’ wood.
Step 3: Saw Off the Original Sill
Slice through the original caulking and sill once you have removed the rotted areas. From here, you can simply pry off each piece of the casing until you are back to the bare bones.
Step 4: Apply Adhesive
Once you have removed the old sill, drill holes roughly every sixteen inches along the original trim. You should then run a waterproof adhesive across the entire length of the trim.
Step 5: Attach the New Sill
You should start by pressing your new sill onto the trim where you applied your adhesive. Then clamp the entire sill into place by drilling screws through the wood.
Step 6: Hide the Screws
The appearance of screws in your new windowsill will be less than appealing, but we haven’t forgotten about them. All you need to do is fill in the screw gaps with adhesive.
Step 7: Apply Wood Hardener
The wood hardener will help in keeping your new sills in perfect condition. They will last for longer with the hardener, and it could help keep rot away for longer.
