Things You'll Need:
- Putty knif
- Small pry bar
- Flat head screw driver
- Several small nails
-
Step 1
Remove the interior stop:
With a wide putty knife, pry loose or unscrew the interior stop at one side. -
Step 2
Swing out the inner sash:
Raise the inner sash slightly and angle it free. The sash cords fit into stile grooves and are held in place with knots. Pull the cords free and lower the sash weights slowly. Set the sash aside. -
Step 3
Remove the parting strip:
Pry the parting strip out of one jamb. It is usually wedged in its channel, perhaps secured by small finish nails, swing the upper sash free and disconnect the cords. -
Step 4
Open the weight pockets:
Remove any weather stripping and look for weight pocket access plates near the bottoms of the jambs. Remove the screws and lift the plates out. If there are no plates, carefully pry off the interior casing on each side of the window to get to the sash weights. -
Step 5
Install sash chains:
Untie the cords from the weights and use an unbroken one as a guide to cut four lengths of sash chains. Feed the chains over the pulleys, down into the weight pockets. Loop the bottom end of each chain through the eye at the top of its weight and secure with wire. -
Step 6
Attach the chains:
Pull each weight to the top of its pocket and hold it there with a nail through the chain. Fasten the outer sash chains to the slots in the sash with screws. Fit the sash into its channels, replace the parting strip, remove the nails and the pulleys, and raise the sash. Then fasten the chains to the inner ash and reinstall it.
