After the sash has been cleared, you can replace parting stops. These are long pieces that separate the sashes. Pam prefers to use standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you could substitute with a scrap piece of wood.

After removing the parting stops and trimming them to your desired length and thickness, apply a thin layer of glazing compound over the bottom of the sash.

Sash Hardware

The hardware that holds window sashes is susceptible to wear and tear from time and usage and the result could be a window or door that won’t open or close easily. The good news is that repairing and replacing this hardware is typically quite simple and inexpensive. If you’re having difficulty opening the sash, spray some oil into the jamb channel. Then, slide the sash up and open to see if this resolves the issue. If not, the issue is likely to be with the balance of the sash and you’ll need to remove the sash in order to access the hardware.

Window sashes need to open and close without much effort. However, this can be a challenge if the weights have been worn out or the sash meeting rail is not properly glazed. This can be due to a variety of factors that include a lack of maintenance and a mismatched weight rating.

If the hinge arms of a window are starting to sag, this can cause the sash to slide and eventually land on the frame in the corner that’s opposite the hinge arm (Photo 1). To resolve this issue, first make sure the sash fits squarely in the frame’s opening and then take it out of the window. If the sash was fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2). 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 general inefficiency. In many instances, a few minor upvc repairs can turn these windows into smooth operators and save homeowners money on energy costs.

To make these repairs to the sash it is essential to have all of the tools needed before you begin. Begin by marking the position of the hinge channel on the frame using pencil (Photo 1). This will allow you to place the channel in the right place when you are finished. Then, remove the sash and remove the hardware including the beads that separate (Photo 2) and the cords or chains that hold it in place.

Sash Weights

Whether your window sash repairs are to replace a broken cord or just to ensure that the windows are functional by replacing worn out weights on sash can improve sash operation and reduce energy costs. Sash weights are heavy lead or iron cylinders that are enclosed inside a hidden compartment and linked to the moveable the sash with rope. They function as counterbalances, allowing you to open and close the window without the need for mechanical or electrical devices. If they fail, sashweights are usually left unnoticed or disabled by homeowners.

A weight in a sash that has fallen out of the cavity is difficult to get back and you’ll need to locate a new one that is suitable for the. You will also require a new piece of string, a length sash cord, and a few sash pulleys that will tie the new sash weights onto the sash cord.

Older windows made of wood are joined using mortise and tenon joints. The wood pegs holding the parts together can be removed with the use of a pin punch and hammer. The majority of these pegs are large on one side, and smaller on the other. It is crucial to remove first the smaller diameter sides. Later sashes made use of glue instead of pins. They can be separated by using a knife or mallet.

After the sash has been removed then you can take out the stopper on the sash and get access to the weight pocket. This is usually done through an opening in the bottom of each jamb. This hole is covered with the wooden panel which can be removed to reveal the interior workings.

After the sash has been stopped and the access panel removed, you will be able to remove the weight from the sash and replace it with new. Weigh the sash first, as the weights you have might not be of the right size. After the new weight has been installed, thread an appropriate length of string through the pulling mechanism. Then nail the string to the boxed frame, but leave a few inches of string protruding from the head to allow for future adjustments.

Sash Cords

In most old double-hung window, a cord or chain is affixed to the weights. This keeps the sashes within the jamb level. As time passes, these cords may become damaged and make it impossible to raise the windows. A new sash cord will restore the ability to move the sash upwards and downwards and hold it in place when it is opened.

The first step in replacing sash cords is to locate and remove the access panels in the jambs. They are usually screwed or nailed into and must be removed. It is possible to remove them using an axe or hammer, but it is always better to lay out dust sheets before beginning any work.

After you have removed the access panel, you can begin working on the sash. Take the narrow beads (also known as “tie rails”) out of their grooves using the chisel or flat bar. They are usually wedged in or nailed in, but they can be snipped out which is why it’s worth your time here. If the sash is in place, remove the mortise and tenon joints with pin punch and hammer or screwdriver, and then take out the wood pegs that are on each component. The sash should move around freely now, however it may require some lubrication to feel less stiff.

Take a measurement of the length of sash cord/chain required to reach the sash slot on the bottom, and the pulley at the top of the jamb. Cut the cord or chain and then attach it as described in the step 6 above. You can employ a hammer and screws or nails, however nails are less likely to cause damage.

It’s best to leave the original weights in place unless you have purchased a kit to replace the counterbalance. It’s cheap to purchase these from salvage shops for architectural purposes and they’ll be easy to install once you’ve got the sash unlocked. Based on the size and shape of your window, you might need to install one or two sashweights to keep the sash open.
