Window Restoration
Updated: March 3, 2011
A stool sits on the sill and is the base the meets the bottom part of the window. The stool will run the length of a single or double window frame. Repairing the stool will take about two hours and $50 dollars. With a few tools and a little muscle, almost anyone can make the repair.
Making the fix is basically a three-step process that is fairly straightforward. It involves removing the stool, milling the new piece, and installing it. You won’t need all that many tools or materials.
The tools needed are:
-Utility knife
-Putty knife
-Hammer
-Pry bar
-Power saw
-Router
-Sandpaper
-Sawhorse
The materials needed are:
-New wood
-Nails
-Casing nails
Before you can remove the stool you first have to remove the stops on either side of the window (four if two windows together) and then move on to the casing trim (usually two pieces for one window and three pieces for two windows).
REMOVING STOPS
1. Use a utility knife to cut paint around the stops.
2. Take a putty knife and hammer and loosen stops.
3. Use a pry bar and carefully remove the stops.
(It’s a good idea to purchase replacement stops ahead of time in case one breaks. In old homes the wood tends to be brittle. But, if you remove the stops intact you can get a refund on the ones not used).
REMOVING TRIM
1. Use utility knife to cut paint.
2. Take a putty knife and hammer to loosen.
3. Use a pry bar and carefully remove the trim.
REMOVING THE STOOL
1. Use a utility knife to cut the paint.
2. Take a putty knife and hammer to loosen.
3. Use a pry bar and carefully leverage the front part of the stool.
4. Use a hammer to pry the stool on the window side where it is nailed to the sill.
5. Carefully remove the stool without damaging the sheetrock or plaster.
If the old stool comes out in one piece it can be used a reference for the new one. The new piece of wood doesn’t have to be the exact same kind. Many of the old stools were made of pine, but the pine cut seventy or eighty years ago was a much higher quality then what is found today. If new pine is used the stool won’t last very long. It’s best to choose a durable wood that not only will match to your window frame, but last for generations.
CUTTING NEW STOOL
1. Take old stool and lay it flat on the new piece of wood.
2. Take a pencil and trace around the old stool.
3. Use power saw to cut the new wood.
4. Use router to round edges to match profile of the old sill.
5. Use sandpaper to smooth any rough edges created by saw or router.
Once the wood is cut, take the new stool and fit it into the window frame. If it fits snugly then it can be installed.
INSTALLING NEW STOOL
1. Hammer in a casing nail about every foot.
2. Take old nails out of stops and casing trim.
3. Replace trim using new nails.
4. Replace stops using new nails.
5. Putty and paint stops, trim, and stool.
Replacing a damaged stool can revive a window area and return your room to its original condition. The process is relatively simple, inexpensive, and satisfying.
