Window Sash Repairs

Most homeowners don't give much thought to window sashes, so long as they're capable of opening and closing and keep the air inside and the air outside out. But with time, they can get worn out, leading to drafts, air leaks, or even sashes sticking.

Sash Weights

If your windows are not closing and opening smoothly or are sluggish the way they should, a defective counterbalancing system could be the reason. It could be caused by the sash being damaged or missing chain or a loose or misaligned the sashweight, or even a broken or cracked pulley.

The sash weights are tiny boxes, usually made of cast iron, that serve to support the sash as well as balance the window's counter-weight system. They are located in the bottom rails of every window frame, and are covered by a wooden access panel that can be removed to reveal their whereabouts. These panels can be removed to allow access to the sash-weight pockets in order to clean, repair or replace them.

If you've had sash windows for some time you likely have a problem with sash weights that cause them to lean or catch. This could be due to the weights being too heavy (they are supposed to be a bit heavier than the top sash) or by having them installed incorrectly (some users have disabled their weight systems by cutting them off and taking them off to save money or turning them in for scrap metal).

To fix this issue, first pry off the stops (the trim along the inner edges of the window where it meets the frame and keeps it in the frame) and set them aside. You'll need to do this with care so as to not damage the profile of the meeting rails. You can then employ a hammer to break the stiles and rails and check them for damage.

After inspecting the stiles and rails of the sash, put dust sheets on the floor and start working. Start by removing the wood pegs from the mortise and tenon joints with a pin punch and a hammer or screwdriver. After removing the pegs you can begin disassembling the sash. Remove the stop moldings for sash and any sash cords still connected.

You can find vintage weights for replacement on the internet or at some home improvement stores, but you should be sure to purchase the right size so as not to over or under weight the sash window restoration.

Sash Cords

Sash cords that are worn out or broken can lead to problems with sash windows. The weights exert constant pressure on the sash cords and this could cause them to break over time. The sashes won't be able to open or close as easily when the cords break. The issue could be caused due to excessive force, aging or lack of maintenance or moisture buildup. It is essential to replace the old cords during window sash repair with new ones made from a material that is durable and resistant to moisture.

Begin by removing the inner stop strips, the thin wood strips that hold the sashes in place, using a utility blade and a chisel. Carefully pry the stops off of the sashes, keeping an eye on any that are cracked or broken. After the stops have been removed, you will be able to access the sash's weights by using an access panel that is cut into the frame's bottom, or by opening the jamb and removing the weight pocket cover.

Accessing the sash cords requires some effort but it's not a problem with the right tools and patience. Remove the old cords first by cutting them in knots, and then pulling them out. Remove the sash and set it aside. Once the sash is off, pull down on the staff bead (the nail that prevents the sash from falling) and insert the nail, which is about 1 foot into the hole in the staff bead. This will temporarily stop the sash from falling while you string the counterweights.

Reattach the sash strings after installing the upper sash. Verify that the sashes move smoothly and are balanced. Install the lower sash window restoration and repeat the procedure. Verify that the sashes are properly set and are moving smoothly.

Reattach the sash cables once you have installed the counterweights. Thread the cord through the pulleys, and then through the knot hole in the sash. Repeat the process for each side of the sash until cords have been replaced and the sashes are functioning normal.
