window sash repairs (wifidb.science)

Sash Weights

If your windows aren't opening and closing smoothly, or are stuck, a faulty counterbalancing system could be the reason. This can occur because of a broken or damaged sash chain or cord as well as a misaligned or unattached sash weight, or a damaged pulley.

The sashweights are small, rounded boxes made of cast-iron that balance the counter-weight system and support the sash. They are situated in the bottom rails of every window frame and are covered with an access panel made of wood that can be removed to reveal their whereabouts. These panels can be removed for access to the sash-weight pockets in order to clean and repair or replace them.

If you've been using sash windows for a long time, it's likely that you have an issue with the sash weights, which cause them to sag or catch. The weights may be too heavy (they should be a bit heavier than the top sash), or installed improperly.

To address this problem, first pull off the stops (the trim along the inner edges of the window that joins the frame and keeps it in the frame) and set them aside. This will require you to be careful so as to not harm the profile of your meeting rails. Then, you can use a hammer to separate the stiles and rails, and inspect them for damage.

Once you've inspected the rails and stiles, lay down dust sheets and start working on the sash itself. Start by removing wood pegs using a pin punch and hammer or screwdriver from the mortise-and-tenon joints. Once the pegs are removed you can begin to disassemble the sash by taking out the sash stop moldings and removing any sash cord knots still in place, and finally, removing the sash windows upvc itself.

The next step is to weigh the sash in order to determine the amount of weight is needed to ensure its proper operation. You can find old-fashioned replacement sashweights online or in a few home improvement stores. Make sure you get the correct size to avoid under or over-weighing the sash.

Sash cords that are worn out or broken can lead to problems with sash windows. The weights put pressure on the sash cords and this could cause them to break over time. If the cords break, the sashes won't be able to open and close easily. The problem may be caused due to excessive force, aging or a lack of maintenance or the buildup of moisture. During window sash repairs, it's important to replace the old cords with new ones made from materials that last and resist moisture.

Begin by removing the inner stop strips, thin wood strips which hold the sashes in the frame with a utility knife and a Chisel. Pry the stops from the sashes carefully, and keep an eye out for any cracked or broken ones. After removing the stops, you can access the sashweights by opening up the jamb or taking out the weight pocket.

It may take a bit more effort to reach the sash cords but with the right tools and a bit of patience, it's not difficult. First, you must remove the old cords by cutting them close to 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 stops the sash from falling) and then insert a nail about a foot long into the hole for the staff bead. This will temporarily keep the sash from slipping away while you string the counterweights.

After reinstalling the upper sash, reattach the sash cords and make sure the sashes are in a balanced position and move smoothly. Reinstall the lower sash, and repeat the procedure. Make sure that the sashes have been properly placed and are moving in a smooth manner.

Once you've completed installing the counterweights, reattach the sash cords, by inserting a sash cord through the pulleys and then threading the other end of the cord through a knot hole in the sash to secure it into the correct position. Repeat the process for each side of the sash and case window repairs until all cords have been replaced and the sashes are functioning normally again.

Also, take note of the condition of glazing putty. It is a hard putty that holds panes glass in place. Examine for cracks and a crumbling surface that could expose the sash's surface to moisture. This could lead to problems with mold and damage to the glass.
