Take the sash off, and mark its size and width so that you can find a replacement weather stripping that matches.

Sash Hardware

The hardware that supports window sashes is prone to wearing out from age and use, and the result can be a window or door that isn't able to open or close easily. It's good to know that replacing and fixing this hardware is usually straightforward and cost-effective. If you're having trouble opening the sash, spray some oil into the jamb channel. Then, you can slide the sash up and open to see if this resolves 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 gain access to this hardware.

The ideal situation is for window sashes to move open and shut with minimal effort but this can be a difficult task when the weights wear out or if the sash's meeting rail isn't properly glazed. This issue can be due to various reasons, including a lack of maintenance and a mismatched weight rating.

If the hinges on windows begin to slide, this could cause the sash to drag, and then eventually to hit the frame in the opposite corner (Photo 1). To remedy the issue, make sure that the sash is in the proper position within the frame opening and then remove it. If the sash has been screwed to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Then, put in 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. Sometimes it is a matter of making a few minor adjustments that can allow these windows to operate smoothly again and save homeowners money on their energy bills.

To make these repairs to the sash it is essential to have all the necessary tools in place before you begin. Begin by marking the location of the hinge channel on the frame using a pencil (Photo 1).

Sash Weights

Sash weights can be changed to enhance the efficiency of your window sash, and also reduce the energy cost. Sash weights are heavy lead or iron cylinders, which are enclosed inside a hidden compartment and connected to the movable the sash with rope. These weights act as counterbalances and allow you to open and shut the window without the need for mechanical or electrical devices. When they fail, sashweights are often left unnoticed or disabled by homeowners.

It's not easy to retrieve the sash-weight that fell from the cavity, so you'll need to find one that fits properly. You will also require a new piece string, a length sashcord and a few sashpulleys to secure the weights you are replacing to the cord.

Older wood windows are joined using mortise and tenon joints. The wood pegs holding the components together can be removed by pin punches and hammers. Most of them have large diameters on one side and a smaller size on the other, which is why it is important to remove the small-diameter sides first. Sashes made later in the century made use of glue instead of pegs. They can be separated by cutting the glue line with an instrument, and then tapping the mortised section loose with mallets.

Once the sash has been released, you can remove the stops on the sash and get access to the weight pockets. Usually, this is done through a hole near the bottom of each jamb. This hole is 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 are able to remove the old weight and replace it. Make sure you weigh the sash prior to you begin, as the weights that were previously used may be a different size than what you require. After the new weight has been installed, run a string through the sash pulling mechanism. Then attach the string to the boxed frame, but only leave a few inches of string protruding from the head to allow for future adjustments.

Sash Cords

The majority of double-hung windows with a history include a chain or cord connected to the weights that keeps the sashes level in the jamb. Over time, these chains may become damaged and make it impossible to raise the windows. A new sash cable will restore the ability to raise and lower the sash and ensure it stays 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 installed by screws or nails and will need to be removed or moved. You could use a hammer and chisel for removing them, but it's always better to lay down dust sheets prior to beginning any work.

After removing the access panel, you are able to begin to work on the sash. Make the small parting beads (also known as "tie rails") out of their grooves with a chisel or flat bar. It is important to be patient because they are usually placed in a wedge or nail. If the sash is still in place, pry out the mortise and tenon joints using the help of a hammer and pin or screwdriver, and then take out the wood pegs attached to each piece. It should now be possible to move the sash back and forth without difficulty, though it will probably need some oiling if it seems stiff.

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