If the sash is double-hung, you'll need to remove the weights as well as their ropes that should have fallen into the pocket of the jamb liner. Once you've taken the sash off using a utility knife, you can use it to remove the weather stripping that was formerly in place at the corners, then remove it manually or using a putty knife.

Once the sash is clear it is time to replace the parting stops. They are long pieces of wood that are used to separate the two sashes. Pam likes to replace these with standard 1/2-inch-by 3/4-inch window trim from the lumberyard, but you can also use a piece of scrap wood.

After removing the stopper and trimming it to length, apply a thin coat of glazing compound on the bottom of the sash. Smooth the compound using a putty tool and let it dry at least one day. Once it's fully cured then apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a new look.

The hardware that supports window sashes can wear out with time and use. This could lead to the window or door that is difficult to open or close. It's important to know that replacing or fixing this hardware is usually straightforward and cost-effective. If a sash is difficult to operate try spraying grease into the jamb channel and then open it to see if this fixes the problem.

Ideally, upvc window repairs sashes must be able to open and close with minimal effort but this is difficult when the weights wear out or if the sash that joins rail isn't properly glazed. This issue can be due to many factors, including an absence of maintenance or an unmatched weight rating.

If the hinge arms of a window 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 the sash is aligned in the frame opening and then remove it. If the sash is screwed onto the hinge arm, remove the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

Because of sagging hinges and a general lack in energy efficiency, windows that are old, especially those in older houses, could be difficult to open and close. In many instances, a few easy repairs can transform these windows into smooth operation again and save the homeowner cash on energy costs.

It is essential to have the tools needed before you begin. Mark the hinge channel's location on the frame (Photo 1) with pencil. This will allow you to put the channel in the proper place when you are finished. Then, remove the sash and remove the hardware including the beads that separate (Photo 2) and the chains or cords which hold it in place. Soften any hardened putty with an electric heat gun set to medium and fitted with a shield for the nozzle. Take off the old sash and store it in an bag that is labeled.

Sash Weights

Sash weights can be replaced to improve the performance of your window sash and decrease energy costs. Sash weights are heavy, lead or iron cylinders that are enclosed in a concealed cavity and connected to the movable the sash with rope. They are counterbalancers which allows the window to be shut and opened without using mechanical or electrical devices. If they fail, sashweights tend to be ignored or disabled by homeowners.

A sash weight that has fallen out of the cavity is difficult to retrieve and you'll need to find a new one that fits correctly. You will also require a new piece string, a length sashcord and some sashpulleys to tie the weights you are replacing to the cord.

Older wood windows are joined by mortise and tenon joints. The wood pegs that keep the parts together can be removed with pin punches and hammers. The majority of them have an enormous diameter on one side and a smaller diameter on the other, which is why it is important to remove the small-diameter sides first. Later sashes used glue instead of pins. They can be separated by using a knife or mallets.

Once the sash is freed and removed, you can take off the sash stop and access the weight pocket. Usually it is done by drilling a hole near the bottom of each jamb. The hole is then covered with a wooden panel that can be removed to reveal the inside workings.

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. Be sure to weigh the sash first because the weights you have may not be of the right size. Once the new weight has been installed, you can thread an appropriate length of string through the pulling mechanism. Then nail the string to the boxed frame, but only leave a few inches of string hanging 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 of the jamb in a balanced manner. Over time these cords can break, making it impossible to raise the window. A new sash cord can restore the ability to move the sash upwards and downwards and keep it in place when it is opened.

To replace sash cords, the first step is to remove the access panels from the jambs. These are usually fixed or screwed in and will need to be removed or repositioned. You might be able to employ a hammer and chisel for removing them but it's best to lay down dust sheets prior to commencing any work.

Once the access panel is removed, you can start working on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves using flat bar or chisel. These are often wedged in or nailed in, but they can be removed, so it's worth taking your time. If the sash is still in place, break the mortise and tenon joints using pin punch and hammer or screwdriver, then unhook the wood pegs that are on each component. It should now be possible to move the sash around freely, though it may require oil if it feels stiff.

With the sash in an open position Take a measurement of the sash chain to reach from the pulley in the top of the jamb to the sash slot at the bottom. Cut the cord or chain and fix it as described in Step 6 above. You can employ a hammer, screws or nails, but nails are less likely to cause damage.

It's best to leave the original weights in place unless you've purchased a kit to replace the counterbalance. They are not expensive and easy to install if you buy them from architectural salvage stores. Depending on the dimensions and shape of your window you might need to install one or two sashweights in order to keep the sash open.
