Sash Hardware

The hardware that holds window sashes is susceptible to wear and tear from age and use, and the result can be a window or door that isn't able to open or close easily. The good thing is that fixing and replacing this hardware is usually relatively easy and affordable.

If the problem persists it's likely to be due to the sash's balance. It is necessary remove the window sash in order to get access to this part of the hardware.

Window sashes need to be able to open and close with minimal effort. However, this can be difficult if the weights are worn out or the sash-to-rail meeting rail is not properly glazed. This could be caused by various reasons, including the lack of maintenance or an unmatched weight rating.

If the hinge arms of a upvc window repair are beginning to slide, this could cause the sash 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 take it off. If the sash has been fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Old windows, especially those in older houses, can be difficult to open and close due to hinges that are sagging and an overall inefficiency. Sometimes it is a matter of making a few minor adjustments that can allow these windows to operate smoothly once more and save homeowners money on energy bills.

Sash Weights

Whether your window sash repairs are to replace a damaged cord or just to ensure that the windows are functional, replacing worn out sash weights will improve sash operation and cut down on energy costs. Sash weights are hefty lead or iron cylinders that are enclosed inside a hidden compartment and attached to the movable sash by a rope. These weights function as counterbalances, allowing you to open and shut the window without requiring mechanical or electrical devices. The sash weights are often disregarded or disabled by homeowners, and are turned into scrap when they break; therefore you may have to locate replacements.

It's not easy to retrieve the sash-weight that fell from the cavity, so you'll want to find one that fits correctly. You will also need an additional piece of string, a length of the sash cord, as well as some sash pulleys that will tie the new sash weights onto the sash cord.

Older wood windows are joined by mortise and tenon joints. Hammers and pins can be used to take out the wood pegs that hold the parts together. The majority of these pegs have a large diameter on one side and a smaller size on the other side, so it is important to remove the smaller-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 weight pockets. This is typically done by drilling tiny holes in the bottom of each jamb. The hole is then covered with a wooden panel that can be removed to reveal the interior workings.

After the sash has been stopped and the access panel removed, you'll be able to take off the weight from the sash and replace it with new. Be sure to weigh the sash first because the weights you have may not be the right size. After the new weight has been installed, run a string through the sash pulling mechanism. Then, you can nail the string to the frame, but only leave a few inches of string hanging from the head for future adjustment.

Sash Cords

In the majority of double-hung windows the chain or cord is affixed to the weights. This supports and keeps the sashes in the jamb level. As time passes, these cords can get damaged and make it impossible to raise windows. A new sash cord can 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. These are usually attached by nails or screws and require removal. It is possible to take them out using a hammer or chisel, but it is always best to lay out dust sheets prior to beginning any work.

After the access panel has been removed, you can begin working on the sash. Utilize a flat bar, or chisel to pry the tiny partsing beads out of their grooves. It's important to take your time, as these are often placed in a wedge or nail. If the sash is still in place, pry out the mortise and tenon joints using a hammer and pin punch or screwdriver, then remove the wood pegs on the components. You should now be able to move the sash around freely, though it will probably need some lubrication if it feels stiff.

With the sash open With the sash in an open position, measure the sash chain or cord to reach from the pulley on the top of the jamb to the sash slot at the bottom.

Unless you've bought a kit that replaces the counterbalance system that was in place before, it is recommended to keep the original balancing weights in place.

Depending on the size and shape of your window you might need to install one or two sashweights in order to keep it open.
