Window Sash Repairs

Sash Weights
If your windows aren't opening and closing smoothly, or are stuck, a faulty counterbalancing system could be the reason. It could be caused by an ailing or damaged sash chain, a misaligned or unattached weight, or a damaged or damaged pulley.
The sash weights are tiny boxes, typically made of cast iron, that support the sash and balance the window's counter-weight system. The sash weights are located at the bottom rails of every window frame. They are protected by a wooden panel which can be removed to reveal their position. The panels can be removed to allow access to the sash-weight pockets in order to clean and repair or replace them.
If you've had sash windows for some time, you may have an issue with the weights on the sash that cause them to lean or catch. The weights could be too heavy (they should be slightly heavier than top sash) or installed improperly.
To resolve this issue to fix this issue, take off the stops (the trim that runs along the inside edge of the window where it meets the frame to hold it in place). Set them aside. This requires you to be gentle in order to not damage the shape of your meeting rails. You can then use a hammer or mallet to break up the stiles from the rails and inspect them for damage or any repairs that must be done.
After you've examined the stiles and rails, lay down dust sheets and then begin working on the sash itself. Begin by taking the wood pegs out of the mortise and the tenon joints using pins and a screwdriver or hammer. Once the pegs are gone, you can begin to disassemble the sash by removing the sash stop moldings, pulling off the sash cord knots that are attached and, finally, taking the sash off itself.

In the case of window sash repairs it is crucial to replace the old cords with new ones that are made from materials that last and resist moisture.
Begin by removing the interior stops and the thin strips of wood that hold the sashes together using a utility knife and a chisel. Pry the stops from the sashes carefully, and be on the lookout for any broken or cracked ones. After the stops have been removed, you can access the sash's weights by using an access panel cut into the frame's bottom, or by opening the jamb and removing the weight pocket cover.
It may take a bit more work to reach the sash cords but with the right tools and a little bit of patience, it's not difficult. Take the old cords out first by cutting them in their knots and then pulling them out. Take the sash off and set it aside. Take off the staff bead, the nail that holds the sash in place. Put a nail of about a foot length into the hole. This will hold the sash in place while you finish stringing counterweights.

After you've installed counterweights, connect the sash cords by placing an sash cord into the pulleys and then threading the cord's other end through a knot hole inside the sash to secure it into place. Repeat this process for each side of the sash until all cords are replaced and the sashes function normal.

Consider the condition of glazing putty. This is a hard putty that is used to hold panes of glass that has been tempered in place. Examine for cracks and a crumbling surface that could expose the sash's exterior to moisture. This can cause problems with mold and damage to the glass.
