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.
How to fix rotten wood around window?
The good news is that replacing the wood around a window doesn’t have to be an expensive or complicated fix. Most small spots can simply be scraped out and filled with epoxy. To deal with extensive rot around the sill or trim, remove the entire section, then cut a new piece to go in its place. If there's damage to the sash itself, your best bet is to have it rebuilt by a specialty contractor to ensure that the job gets done right.
How to get rid of rotten wood?
Scrape out small rotted spots with a screwdriver or chisel. Dig the tip of your tool into the bad wood and work it free of the frame.

Continue gouging and scraping until only hard, healthy wood remains.
How long does epoxy take to cure?
Allow the epoxy to cure for at least 3-4 hours. As it sits, it will gradually expand to continue filling out the damaged area. It will then harden to form a strong, watertight seal that will do a much better job of keeping unwanted moisture out than new wood or paint alone.

Q: One of our windowsills appears to be rotting. Can it be replaced without buying a new window?
Remove the Side Casings
The casing comes off to clear the way for removing the old sill. If the casings are rotting, as here, replace them, too. Slice through the caulk bead between the siding and the casing, then carefully pry off each piece. Save the trim to use as templates for the new ones.
Saw Off the Old Sill
Make a plumb cut flush with the sheathing along the length of the rotten sill. A circular saw with a beveled blade can handle most of the cutting, but for the sill ends where a circ saw can't reach, switch to a multitool, like this Fein Multimaster equipped with an oscillating saw blade. Smooth the cut with a few strokes of a hand plane.
Apply the Adhesive
Repair any rotten spots on the old sill with epoxy. Trim the back edge of the new sill as needed so that its lower edge fits tightly against the siding and its back edge fits against the old wood. Drill pilot holes every 16 inches or so through the new sill's front and back edges. Run a bead of waterproof, marine-grade adhesive along the old sill.
Attach the New Sill
Press the new sill into the adhesive, and immediately clamp it in place by driving 3½-inch deck screws through the plastic and into the wood. Stop when the heads are about ¼ inch below the sill surface. Immediately wipe up any adhesive that squeezes out. Fill any gaps between the old and new sill with adhesive.
Hide the Screwheads
Cover each screwhead with a dollop of a white, two-part acrylic adhesive, such as Bond&Fill FastCure. (This also works as an adhesive in Step 3.) Overfill the recess slightly. When the adhesive hardens completely, in about 30 minutes, sand it flush.
Install the Side Casing
Squeeze a bead of caulk beside the ends of the siding, and nail the new casing in place. Here, I used cellular PVC trim boards and 8d stainless-steel ring-shank nails. Set the nailheads slightly below the surface, and cover each one with a dab of the two-part adhesive. After the dabs harden, sand them flush.
