Sash Weights If your windows are not opening and closing smoothly, or are stuck in a stuck position, a malfunctioning counterbalancing system could be the reason. This could be due to a missing or damaged sash cord/chain, an unattached or misaligned sash weight, or a damaged pulley. The sashweights are tiny boxes made of cast-iron, which balance the counter-weight system and help support the sash. They are situated in the bottom rails of each window frame and are covered with a wooden access panel that can be cut open to reveal their location. The panels can be removed for access to the weight pockets in the sash to clean, repair or replacement. If you've had sash windows for some time, you may have an issue with the sash weights that cause them to sag or catch. The weights can be too heavy (they should be a little heavier than the top sash), or installed improperly. To fix this problem take out the stops (the trim that runs along the inside edge of the window where it joins the frame to hold it in place). Put them away. You'll need to do this gently so as to not damage the appearance of the overlapping rails. You can then make use of a mallet or hammer to separate the stiles and rails and check them for damage or any repairs that require to be done. Once you've inspected the stiles and rails lay down a few dust sheets and then begin working on the sash itself. Begin by removing the wood pegs using a pin punch and a screwdriver or hammer from the mortise and tenon joints. After the pegs have been removed you can begin to disassemble the sash by taking out the stop moldings for sash as well as removing any sash cord knots connected, and then taking the sash off itself. The next step is to weigh the sash and figure out how much weight is required for its proper functioning. You can purchase vintage replacement sashweights on the internet or at some home improvement stores. Be sure to purchase the right size to avoid over or under-weighting the sash. Sash Cords Sash cords that have worn out or broken can lead to sash window issues. Sash cords are under constant pressure from the weights, which could cause them to break over time, especially when they're not maintained properly. The sashes will not open or close as easily if the cords break. The issue could be caused by a variety of things, including excessive force, aging, the lack of maintenance and moisture buildup. In the case of window sash repairs it is crucial to replace the old cords with new ones constructed from materials that last and resist moisture. Begin by removing the inner stops which are the thin strips of wood that keep the sashes in place using a utility knife and a the chisel. Remove the stops from the sashes carefully, and keep an eye out for any broken or cracked ones. After removing the stops, you can get access to the weights on the sash by opening the jamb or removing the weight pocket. It may take a bit more work to reach the sash cords, but with the right tools and a bit of patience it is not difficult. Get rid of the old cords first by cutting them at knots, and then pulling them out. Then, remove the sash from the frame and put it aside. Once the sash is off and you have pulled it down, grab the staff bead (the nail that prevents the sash from falling) and then insert the nail, which is about one foot long into the staff bead hole. This will hold the sash on its place while you string counterweights. After installing the upper sash again then reattach the sash cords and ensure that the sashes are in a balanced position and move smoothly. Then, reinstall the lower sash, and repeat the process, making sure that the sashes are properly seated and moving smoothly. Once you've completed installing the counterweights, reconnect the sash cords by putting a sash cord through the pulleys and then threading the other end of the cord through a knot hole inside the sash to secure it into place. Repeat this procedure on both sides of the sash to ensure that the sashes function normally again. Air leaks and drafts Over time, materials that connect your sash window to the frame of your home begin to degrade. This leads to drafts and energy loss. A thorough inspection will reveal the trouble spots and help you determine the best options for repairs to your window sash.

It is good to know that fixing drafty windows is a relatively simple task that can reduce your energy costs and enhance indoor comfort. The first step is to inspect the window's exterior. Check for areas of bare caulking or broken wood which exposes the window to cold air. Examine the sash's interface with the frame including the parting beads and staff bead. Examine the condition of weather stripping at these points (felt strips or tape) to determine if they're intact and effective. If not, it's time to be replaced. Finally, consider the state of glazing putty, a hard putty that holds panes glass in place. Look for cracks and crumbling that can expose the sash's surface to moisture. This can cause problems with mold and damage to the glass. Apply a fresh layer glazing putty to the inside of the window to correct the problem. To fix the glazing points, make use of a flat-bladed screwdriver push them into place. Wrap a piece of fabric and foam around each point. This will act as insulation against cold air.

They can be removed using a blade that is attached to small pry-bars or a putty-knife. They are usually put in place with nails and then painted, so you must be careful not to damage them or the sliding sash. After you've removed your parting beads, the next task is to remove the pockets. These are small pieces of wood which are fixed into the frame at the bottom. They permit access to the sashweights. After the nails have been removed then you can move the sash up and down in order to make sure it moves smoothly. If it doesn't then there may be a problem with the counterweights and the sash cords.
