Window Sash Repairs The majority of homeowners don't pay attention to window sashes as long as they're capable of being opened and closed and keep the air inside and the air out. As time passes, window sashes can wear out and cause air leaks, drafts or even sashes that are stuck. The author uses a sash that is placed on an easel to work glazing points into the gap. He also scrapes paint off and then applies a wood preservative on the frame. Sash Weights If windows aren't opening or closing with ease or are sagging due to a problem with the counter-balancing system, it's possible that a could be the cause. This can be caused by the sash being damaged or missing chain or a loose or misaligned sashweight, or a broken or cracked pulley. The sashweights are tiny boxes made of cast-iron, which balance the counter-weight system as well as support the sash. The sash weights are situated on the bottom rails of every window frame. They are protected by wood panels which can be removed to reveal their location. These panels can be removed for access to the sash weight pockets to clean and repair or replace them. If you've had sash windows for some time, you may have a problem with sash weights, which cause them to sag or catch. The weights could be too heavy (they should be a little heavier than the top sash) or they've been installed incorrectly. To remedy this issue take out the stops (the trim that runs along the inside edge of the window at the point where it joins with the frame to keep it in place). Put them away. This requires you to be gentle in order to not damage the profile of your meeting rails. Then, you can employ a hammer to break the stiles and rails and check them for damage. After examining the rails and stiles of the sash, place dust sheets on the floor and begin working.

Once the pegs are gone then you can begin to disassemble the sash by removing the sash stop moldings as well as removing any sash cord knots still connected, and then removing the sash itself. Next you will want to weigh the sash in order to figure out how much weight is needed for its proper functioning. You can find old weights for replacement on the internet or at some home improvement stores, but ensure that you purchase the right size so as not to over or under weight the sash. Sash Cords Sash cords that are worn out or broken can cause problems with sash windows. The weights exert constant pressure on the sash cords and this could cause them to break over time.

Once the stops are removed, you will be able to access the sash weights via an access panel cut into frame's bottom or by opening the jamb and removing the cover that covers 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. Get rid of the old cords first by cutting them at their knots and then pulling them out. Remove the sash and set it aside. After the sash has been removed, pull down on the staff bead (the nail that stops the sash from falling) and then insert the nail, which is about a foot long into the hole in the staff bead. This will temporarily stop the sash from slipping away while you string the counterweights. After installing the upper sash again then reattach the sash cords and ensure that the sashes are balanced and move smoothly. Then, reinstall the lower sash and repeat the process, checking that the sashes are properly seated and 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 the cords are replaced and the sashes function normally again.
