Then, take the sash off and mark its width and height so that you can locate the appropriate weather stripping replacement to match.

Next, remove the sash and place it on a table to allow access to all four sides. If your sash was double-hung, remove the ropes and weights that should be buried inside the jamb lining. Once you've taken the sash off and the weights, use a utility knife to cut away the old weather stripping at the corners. Then, remove it by hand or using a putty knife.

After the sash has been cleaned, you can replace the parting stops. These are long pieces that separate the sashes. Pam prefers standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. However, you can substitute for a scrap piece of lumber.

After removing the parting stops and cutting them to the desired length and thickness, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty tool, and let it dry at least one day. When it's completely dried and dried, apply a second coat of acrylic latex paint. This will protect the putty, and give your sash a fresh look.

Sash Hardware

The hardware that supports window sashes can wear out over time and with use. This could result in windows or doors that is difficult to open or close. It's a good idea to know that replacing and repairing this hardware is often easy and affordable. If a sash isn't easy to operate, try spraying some lubrication into the jamb channel then slide it open to see if this fixes the problem. If not, the problem is most likely due to the balance of the sash and you'll need to remove the sash to access the hardware.

The ideal situation is for window sashes to move open and shut with very little effort, however, this can be a difficult task when the weights are worn or if the sash that joins rail isn't properly coated. This could be caused by various reasons that include the lack of maintenance or an unmatched weight rating.

If the hinge arms on windows begin to slide, this can cause the sash drag and then hit the frame at the opposite corner (Photo 1). To fix the problem ensure that the sash is centered in the frame opening and then remove it. If the sash was attached to the hinge arm, unbolt the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).

Because of sagging hinges and a general lack in energy efficiency, windows that are old, especially those in older homes, can be difficult to open and close. In most instances, a few minor repairs can transform these windows into smooth operation and save homeowners money on energy bills.

It is important to have the tools you need before you start. Begin by marking the position of the hinge channel on the frame with a pencil (Photo 1). This will help you get the channel back in the correct position after you've finished. Take the sash off and take out all the hardware including the parting beads, cords, and chains that hold the sash in place.

Sash Weights

No matter if your window sash repair needs are to replace a damaged cord or to ensure that the windows are functional by replacing worn out weights for sash will improve its operation and help reduce energy costs. Sash weights are made of heavy iron or lead cylindricals that are contained in a hidden cavity and connected by ropes to the moveable window sash. They are counterbalancers which allows the window to be shut and opened without the use of electrical or mechanical devices. If they fail, sashweights tend to be ignored or window repairs disabled by homeowners.

It is difficult to recover a sash-weight that has fallen from the cavity, so you'll want to find one that fits properly. You will also require a new piece of string, a length of sash cord and some sash pulleys to tie the new sash weights onto the sash cord.

Older windows made of wood are joined by mortise and tenon joints. Pin punch and hammer can be used to take out the wood pegs that hold the parts together. The majority of these pegs are large on one side, and smaller on the other. It is essential to first remove the smaller diameter sides. Sashes that were made later in the century used glue instead of pegs and can be separated by cutting the glue line using a knife, then tapping the mortised part loose with mallets.

After the sash is released, you can remove the stops on the sash and get access to the pockets for weights. Usually, this is done through an opening at the bottom of each jamb. The hole is then covered with an unfinished wooden panel that can be removed to reveal the inside workings.

Once you have the sash stopped and the access panel removed, you will be able to remove the weight from the sash and replace it with new. Make sure you weigh the sash prior to you do this, as the weights that were previously used may be different sizes than the one you need. Once the new weight is in place you can tie a string around it and thread it through the pulley for the sash. Then attach the string to the frame, leaving a few inches of string hanging from the head to allow for future adjustments.

Sash Cords

Most double-hung windows of the past include a chain or cord connected to the weights that keeps the sashes level in the jamb. As time passes, these cords may become damaged and make it impossible to raise windows. A new sash cord will restore the ability to move the sash up and down and will keep it in its position when it is opened.

The first step in replacing sash cords is to find and remove the access panels within the jambs. These are usually fixed or screwed in and will need to be removed or moved. It may be possible to remove them using a hammer or chisel, but it is always best to lay out dust sheets prior to starting any work.

After the access panel has been removed, you can start working on the sash. Utilize a flat bar, or chisel to pry the tiny parting beads from their grooves. It's important to be patient, as these are often stuck or nailed to the floor. If the sash is still in place, pry the mortise-and-tenon joints out with a hammer or screwdriver and then take out each wood peg. You should now be able to move the sash back and forth without difficulty, though it may require lubrication if it feels stiff.

Take a measurement of the length of sash chain/sash cord required to reach the sash slot at the bottom from the pulley on the top of the jamb. Cut the cord/chain, and then secure it in the previous step. You can use nail, hammer or screws. However nails are less likely than screws to cause damage.

It's best to leave the original weights if you've purchased a kit that will replace the old counterbalance. They're not costly and simple to install if you buy them from salvage shops for architectural use. Based on the size of your window, one or two sashweights may be needed to keep the sash in an open position.
