Removing the Old Window and Frame- Run a utility knife along the edge where the trim meets the wall (figure A) to avoid ruining paint job. Then pry off the old trim.
- Chip away the plaster to find the rough opening. Measure the rough opening carefully so you can be sure to get the correct window size. Measure between the jack studs, up to the header and to the sill plate beneath the window.
The old window is removed in the next segment.
