Sash Hardware

The hardware that supports window sashes is prone to wearing out from the wear and tear of use and the result could be a window or door that won't open or close easily. The good news is that fixing and replacing this hardware is generally very simple and cost-effective. If a sash is difficult to operate, try spraying some grease into the jamb channel, and then slide it open to see if this solves the issue. If the problem persists, it is most likely the sash balance. You will need to take off the window sash in order to reach this hardware.

Sashes for windows should be able to open and close without much effort. However, this may be difficult if the weights are worn out or the sash connecting rail isn't covered with. This could be caused by a variety of factors, including a lack of maintenance and an unmatched weight rating.

If the hinge arms of a window are beginning to sag, this can cause the sash's to drag and eventually strike the frame in the corner that's directly opposite the hinge arm (Photo 1). To correct the issue, make sure that the sash is aligned in the frame opening and then remove it. If the sash is screwed onto the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Old windows, particularly those in older houses, can be difficult to open and close due to sagging hinges and an overall lack of energy efficiency. In most cases, a few simple repairs can turn these windows into smooth operators and save homeowners money on energy bills.

To complete these repairs to the sash it is essential to have all of the necessary tools in place before you begin. Mark the hinge channel location on the frame (Photo 1) with a pencil. This will allow you to get the channel back on the correct position after you've finished.

Sash Weights

Sash weights are able to be replaced to improve the performance of your window sash and decrease the energy cost. Sash weights are composed of heavy iron or lead cylindricals that are contained inside a concealed cavity, and connected by ropes to the moveable window sash. They are counterbalancers which allows the window to be shut and opened without the use of electrical or mechanical devices. The sash-weights are typically neglected or ignored by homeowners, and are turned into scrap when they fail; therefore you might need to locate replacements.

A weight in a sash that has fallen out of the cavity is difficult to get back and you'll need to find a new one that is suitable for the. You will also require a new piece of string, a length sashcord and a few sashpulleys for tying the weights you are replacing to the cord.

Older wood windows are joined with mortise and tenon joints. Hammers and pins can be used to take out the wood pegs holding the parts together. The majority of them have a large diameter on one side and a smaller diameter on the other, so it is important to remove the smaller-diameter sides first. Sashes that were made later in the century made use of glue instead of pegs. They can be separated by cutting through the glue line using a knife, then tapping the mortised part loose using a mallet.

After the sash has been removed, you can remove the sash stop and access the weight pocket. Usually it is done by drilling an opening in the bottom of each jamb. This hole is then covered by a wooden access panel that can be cut off to let you see the inner workings of the frame.

When the sash has been shut off and the access panel is removed, you can remove the old weight and replace it. Be sure to weigh the sash first because the weights you have might not be of the right size. Once the new weight is in place then tie a string to it and thread it through the sash pulley. Then attach the string to the boxed frame, but only leave a few inches of string protruding from the head to allow for future adjustments.

Sash Cords

The majority of double-hung windows with a history include a chain or cord attached to the weights which supports and keeps the sashes in balance in the jamb. Over time, these cords could break, making it impossible to raise the window. A new sash cord can restore the ability to move the sash up and down and hold it in place when opened.

The first step in replacing sash cords is to locate and remove the access panels in the jambs. They are usually installed by screws or nails and will need to be removed or moved. It is possible to remove them with an axe or hammer, but it is always better to lay out dust sheets prior to starting any work.

After the access panel has been removed, you can begin working on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves using flat bar or chisel. It is essential to be patient as they're often stuck or nailed to the floor. If the sash is still in place, break the mortise and tenon joints free with a screwdriver or hammer and then remove each wood peg. It should now be possible to move the sash back and forth freely, though it might require lubrication if it feels stiff.


Take a measurement of the length of the sash chain or sash cord needed to reach the sash slot at the bottom of the pulley at the top of the jamb. Cut the chain or cord and fix it as described in Step 6 above. You can do this with a hammer, nails, or screws. However, nails are less likely to cause damage.

It's best to leave the original weights if you have purchased a kit to replace the counterbalance. They are not expensive and simple to install if purchased them at architectural salvage stores.
