This issue could be caused by a number of reasons, such as lack of maintenance or by a mismatched weight rating for the specific sash.

If the hinges on windows begin to slide, this can cause the sash drag and eventually hit against the frame in the opposite corner (Photo 1). To resolve this issue, first make sure the sash is squarely inserted into the opening of the frame and then remove it from the window. If the sash is screwed to the hinge arm, you’ll have to loosen the hinge arm and replace it (Photo 2). Next, install the new sash (Photo 3).

Windows that are old, especially in older homes, can be difficult to open and close because of sagging hinges and an overall lack of energy efficiency. In many instances, a few easy repairs can turn these windows into smooth operation again and save the homeowner money on energy costs.

To complete these repairs to the sash it is essential to have all the necessary tools in place before you begin.

Sash Weights

Whether your window sash repairs are to replace a damaged cord or just to ensure that the windows are functional by replacing worn out sash weights will improve sash operation and reduce energy consumption. Sash weights are composed of iron or lead cylindricals that are contained inside a concealed cavity, and connected by a rope to the movable window sash. They are counterbalancers, allowing the window to be closed and opened without the need for mechanical or electrical devices. When they fail, sashweights are often neglected or not used by homeowners.

A weight in a sash that has fallen out of the cavity is difficult to recover It is therefore important to find a new one that fits properly. You will also require a new piece string, a length sashcord and a few sashpulleys for tying the new weights to the cord.

Mortise and Tenon joints are used to join windows made of older wood. The wood pegs that hold the components together can be removed by the use of a pin punch and hammer. Most of these pegs have a large diameter on one side and a smaller one on the other, which is why it is crucial to take out the small-diameter sides first. Later sashes made use of glue instead of pins. They can be cut by using a knife and a mallet.

Once the sash has been removed, you can take off the stops on the sash and get access to the pockets for weights. This is usually done through an opening in the bottom of each jamb. The hole is then covered with an access panel of wood which can be removed so that you can observe the inner workings of the frame.

Once the sash is stopped and the access panel has been removed, you can take off the weight that was previously installed and replace it. Weigh the sash first, as the weights you have might not be the correct size. After the new weight is installed, tie a string to it and thread it through the sash pulley. Then nail 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

In the majority of double-hung windows, a chain or cord is connected to the weights. This supports and keeps the sashes within the jamb level. As time passes, these cords can become damaged and render it impossible to raise windows. A new sash cord can restore the ability to move the sash upwards and downwards and will keep it in its place when opened.

The first step to replace sash cords is to find and take out the access panels located in the jambs. They are typically attached by nails or screws and need to be removed. You may be able to employ a hammer and chisel for removing them however, it is always best to lay down dust sheets prior to beginning any work.

If the sash is still in place, remove the mortise and window sash repairs the tenon joints by using pin punch and hammer or screwdriver, and then take out the wood pegs on the components.

Measure the length of sash cord/chain required to reach the sash slot at the bottom, and the pulley at the top of the jamb. Cut the cord or chain and attach it in Step 6 above. You can use either a hammer, nails, or screws. However, nails are less likely to cause damage.
