The first step for repair sash window damage is to fix weather stripping. It's found on both the sash and frame. If it's loose or worn out, it can lead to drafts and other issues. To fix it, begin by determining your window's brand and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its height and width, so you can find replacement weather stripping to match.

Next, remove the sash and set it on a work surface to allow access to all four sides. If your sash has been double-hung, take out the ropes and weights that should fall into the pocket inside the jamb lining. Once you've taken the sash off and the weights, use a utility knife to remove the old weather stripping at the corners, and then remove it manually or with a putty knife.

When the sash is clean and clean, you can put in the parting stops. These are long pieces wood that separate the two sashes. Pam prefers to replace them with standard 1/2-inch-by 3/4-inch window trim from the lumberyard, however you can also use a piece of scrap wood.

After removing the stopper and trimming it to length and then apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty tool and let it dry for at least one day. After the putty has completely cure, you can apply a topcoat of acrylic. This coating will protect the putty and give your sash a new look.

Sash Hardware

The hardware that holds the window sashes can wear out over time and with use. This could result in the window or door that is difficult to open or UPVC repairs close. It's important to know that replacing and repair of this hardware is typically easy and affordable. If a sash is difficult to operate try spraying oil into the jamb channel, and then slide it open to see if this fixes the problem. If not, the issue is most likely due to the sash balance, and you'll have to take off the sash to access the hardware.

Sashes for windows should be able to open and close with little effort. However, this could be a challenge if the weights have been worn out or the sash meeting rail is not properly coated. This issue could be caused by many factors that include a lack of maintenance and 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 opposite the hinge arm (Photo 1). To address this issue, first make sure the sash is firmly seated in the opening of the frame and then take it out of the window. If the sash has been screwed to the hinge arm, you'll need to remove the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).

Due to sagging hinges, and a general lack of energy efficiency, older windows especially in older houses, could be difficult to open or close. In most instances, a few easy repairs can turn these windows into smooth operation for the first time and save the homeowner money on energy bills.

It is important to have the tools you require before you begin. Mark the location of the hinge channel on the frame (Photo 1) using pencil. This will assist you in getting the channel back on position correctly after you've completed.

Sash Weights

Sash weights can be replaced to enhance the efficiency of your window sash and reduce the energy cost. Sash weights are made of iron or lead cylindricals that are contained inside a concealed cavity, and attached by ropes to the moveable window sash. They provide counterbalance that allows the window to be opened and closed without using mechanical or electrical devices. When they fail, sashweights tend to be ignored or disabled by homeowners.

A weight in a sash that has fallen out of the cavity is difficult to retrieve It is therefore important to locate a new one that fits properly. You will also require an additional piece of string, a length of the sash cord, as well as some sash pulleys that will tie the new sash weights to the sash cord.

Mortise and Tenon joints can be used to join old wood windows. Pin punch and hammer can be used to remove the wood pegs holding the components together. The majority of them are large on one side, but smaller on the other. It is crucial to remove first the smaller diameter sides. 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 with the help of a knife, and then tapping the mortised section loose with a mallet.

After the sash is removed then you can take out the sash stop and gain access to the weight pocket. Usually, this is done through an opening in the bottom of each jamb. This hole is then covered by an access panel of wood that can be cut off to let you see the inner workings of the frame.

Once the sash is stopped and the access panel is removed, you can take off the old weight and replace it. Be sure to weigh the sash first, as the weights you have may not be the right size. After the new weight is installed, run the string through the sash pulling mechanism. Then attach the string to the frame, but leave a few inches of string hanging from the head to allow for future adjustments.

Sash Cords

In the majority of old double glazing-hung windows, a chain or cord is affixed to the weights. This helps keep the sashes within the jamb level. As time passes, these cords can become damaged and render it impossible to raise windows. A new sash cable can restore the ability to raise and lower the sash, and ensure it stays in place when opened.

The first step in replacing sash cords is to find and take out the access panels located in the jambs. They are usually screwed or nailed in and require removal. You could use a hammer or chisel for removing them but it's best to lay down dust sheets before beginning any work.

After you have removed the access panel, you are able to begin to work on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves using flat bar or chisel. They are usually wedged in or nailed, but they can be snipped out, so it's worth taking your time here. If the sash is still in place, pull the mortise-and tenon joints using a hammer or screwdriver and then remove each wood peg. The sash should be able move freely now, but it might require some lubrication to feel less stiff.

With the sash open Take a measurement of the sash chain to reach from the pulley in the top of the jamb to the sash slot on the bottom. Cut the cord or chain and attach it in the previous step. You can either employ a hammer, screws or nails, however nails are less likely to cause damage.

It is best to keep the original weights in place unless you've purchased a kit to replace the counterbalance that was previously installed.
