Window Sash Repairs

Sash Weights

When your windows aren't opening and closing with ease or are sagging, a faulty counter-balancing system may be to blame. It could be caused by the sash being damaged or missing chain, a misaligned or unattached sashweight, or a broken or cracked pulley.

The sashweights are small boxes made of cast iron that support the counter-weight system as well as support the sash. They are found in the bottom rails of each window frame, and are covered by an access panel of wood which can be opened to reveal their whereabouts. These panels can be removed for access to the sash weight pockets for cleaning, repairs or replacement.

If you've had sash windows for some time you likely have a problem with sash weights, which cause them to sag or catch. The weights may be too heavy (they should be slightly heavier than top sash) or installed in a way that isn't correct.

To address this issue, first pry off the stops (the trim along the inside edges of the window where it joins the frame and holds it in place) and set them aside. It is important to do this gently so as to not damage the shape of the two rails. You can then use a hammer for separating the rails and stiles, and then inspect them for damage.

After you've examined the stiles and rails, lay down dust sheets and begin working on the sash itself. Start by removing wood pegs using a pin punch and a screwdriver or hammer from the mortise-and tenon joints. After removing the pegs, you can start disassembling the sash. Take off the sash stop moldings and any sash windows repair cords that are still in place.

Sash Cords

The majority of sash window problems result from damaged or worn sash cords. Sash cords are under constant pressure from the weights which can cause them break over time, particularly when they're not maintained properly. If the cords break, the sashes will no longer open and close easily. The issue could be caused by excessive force, ageing, lack of maintenance, or moisture buildup. During window sash repairs it is essential to replace the old cords with new ones made from materials that last and resist moisture.

Start by removing the internal stop strips, thin wood strips that hold the sashes into place Utilizing a utility blade and a Chisel. Pry the stops from the sashes with care, and keep an eye out for cracked or broken ones. After removing the stops, you can access the sashweights by opening the jamb or taking out the weight pocket.

It requires a bit of effort to reach the sash cords but with the right tools and a little bit of patience, it's not difficult. First, take off the old cords by cutting them near their knots, and then pulling them away. Then, take the sash from the frame and set it aside. After the sash has been removed, pull down on the staff bead (the nail that keeps the sash from falling) and insert one nail that is about one foot long into the staff bead hole. This will stop the sash from falling while you finish stringing the counterweights.

Reattach the sash strings after reinstalling upper sash. Check that the sashes move in a smooth manner and are in a balanced position. Reinstall the lower sash and repeat the procedure. Check that the sashes are properly set and are moving in a smooth manner.

After you've finished installing counterweights, connect the sash cords by placing a sash cord through the pulleys, and then threading the cord's other end through a knot hole in the sash to secure it in place. Repeat this process for both sides of the sash to ensure that the sashes function normally again.
