Then he mixed the two-part epoxy filler. It smelled like a chemistry lab and felt like warm taffy. He pressed it into the cavity with a putty knife, overfilling slightly, mounding it above the original surface. He let it cure for a full 24 hours. Patience, he reminded himself. Rot took years. Epoxy takes a day. Now came the art. The cured epoxy was harder than the original oak. Hendricks pulled out a block plane and a rasp. He shaved the epoxy down to the level of the old sill, then used the rasp to carve the subtle front slope—the “drip edge”—that shed water away from the glass.
“The whole window’s shot,” said the young contractor, tapping it with a hammer. “Needs full replacement. Twelve thousand dollars.” how to repair rotted window sills

Shape the repair to shed water. The sill must slope away from the house, about 5 degrees. Any backward tilt is a suicide pact. Chapter Five: The Armor Hendricks sanded the whole sill smooth—old wood and new epoxy together—with 120-grit, then 220. Dust flew. The patch became indistinguishable from the original under a coat of primer. He let it cure for a full 24 hours
Hendricks smiled. He’d been fixing things since before the contractor was born. He knew the difference between a lost cause and a patient resurrection. “No,” he said. “It needs a story. A proper one.”
