Window Sash Repairs

Most homeowners don't think much about window sashes -- insofar as they can be closed and opened, they keep outside air out and the interior air in. However, over time, they can get worn out, leading to drafts, air leaks, or even sashes that stick.

Sash Weights

If windows aren't opening and closing with ease or are sagging the way they should, a malfunctioning counter-balancing system could be at fault. This could be due to an ailing or damaged sash chain or a sashweight that is not aligned properly or not attached to a weight, or a damaged or cracked pulley.

The sash weights are tiny boxes, typically made of cast iron, that serve to support the sash as well as help balance the counter-weight system of the window. They are found in the bottom rails of every window frame, covered by an access panel made of wood that can be cut open to reveal their position. These panels can be removed to allow access to the sash-weight pockets to clean, repair or replace them.

You may have problems with the sashweights, if you've been using your sash windows for long enough. They might lean or catch. The weights can be too heavy (they should be a bit heavier than the top sash) or installed improperly.

To fix this problem, remove the stops (the trim that runs along the inside edge of the window at the point that it joins the frame to keep it in place). Set them aside. This requires you to be gentle so as to not damage the shape of your meeting rails. Then, you can use a hammer for separating the stiles and rails and then inspect them for damage.

After inspecting the stiles and rails of the sash, put some dust sheets on the floor and start working. Start by taking the wood pegs out of the mortise and tenon joints with pin punches and a screwdriver or hammer. After you have removed the pegs you can begin disassembling the sash. Remove the stop moldings for sash and any timber sash windows cords that are still in place.

Next you will want to weigh the sash in order to figure out how much weight is needed for the proper functioning. You can buy vintage replacement sashweights online or at some home improvement stores. Make sure you get the correct size to avoid over or under-weighting the sash.

Sash Cords

Often sash window problems stem from damaged or worn sash cords. Sash cords endure constant pressure from the weights which can cause them break over time, especially if they're not properly maintained. If the cords break, sashes won't be able to open and close easily. The issue could be caused due to excessive force, aging or a lack of maintenance or the buildup of moisture. During window sash repairs it is essential to replace the old cords with new ones that are made from a material that will last and resist moisture.

Start by removing the internal stop strips, the thin wood strips that hold the sashes in place with a utility knife and a chisel. Remove the stops off the sashes carefully, and keep an eye out for cracked or broken ones. Once the stops are removed, you can access the sash weights via an access panel cut into bottom of the frame or by opening the jamb, and then removing the weight pocket cover.

It takes a little extra work to reach the sash cords but with the right tools and a bit of patience it is not difficult. Take the old cords out first by cutting them in their knots, then pulling them out. Take the sash off and set it aside. Take off the staff bead, the nail that keeps the sash in place. Insert an approximately one foot length into the hole. This will hold the sash in place as you finish stringing counterweights.

Reattach the sash string after installing the upper sash. Make sure that the sashes are moving smoothly and are in a balanced position. Then, you can reinstall the lower sash, and repeat the process, ensuring that the sashes are correctly seated and moving smoothly.

After you've installed the counterweights, reattach the sash cords, by inserting the sash cord through the pulleys and then threading the cord's other end through a knot hole inside the sash, ensuring it is secured in the correct position. Repeat the process for each side of the sash until cords are replaced and the sashes are operating normally.

Then, think about the condition of glazing putty. It is a hard putty that holds panes of glass in place. Check for cracks and crumbling that can expose the sash's exterior to moisture. This can lead to problems with mold and damage to the glass.
