After you have removed the sash using the utility knife, you can remove the weather stripping that was left by hand or using the putty blade.

When the sash is clean, you can replace the parting stops. These are long pieces of wood that divide the two sashes. Pam prefers the standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. However, you can also substitute with a scrap piece of wood.

After removing the parting stops and trimming them to the desired length and thickness, apply a thin layer of glazing compound over the bottom of the sash.

Sash Hardware

The hardware that holds window sashes is susceptible to wear and tear due to time and usage, and the result can be a window or door that isn't able to open or close easily.

Ideally, window sashes must swing open and closed without effort, however, this can be a difficult task when the weights are worn or if the sash meeting rail isn't properly glazed. This issue can be caused by a number of things, such as lack of maintenance or by the wrong weight rating for the specific window sash.

If the hinge arms on the window begin to move, this can cause the sash drag, and then eventually to hit the frame at the opposite corner (Photo 1). To remedy the issue make sure the sash is aligned in the frame's opening and take it off. If the sash is screwed to the hinge arm, you'll have to loosen the hinge arm and replace it (Photo 2).

Because of sagging hinges and a general lack of energy efficiency, windows that are old especially in older houses, could be difficult to open and close. In most instances, a few easy repairs can transform these windows into smooth operators for the first time and save the homeowner money on energy costs.

In order to make these repairs to the sash, it's important to have all the necessary tools lined up before you begin. Begin by marking the location of the hinge channel on the frame with a pencil (Photo 1). This will help you to position the channel in the proper location after you've completed.

Sash Weights

If your window sash repairs are to replace a broken cord or just to ensure that the windows are functional, replacing worn out sash weights will improve sash operation and reduce energy consumption. Sash weights consist of heavy iron or lead cylinders that are enclosed in a hidden cavity and attached by ropes to the movable window sash. These weights provide counterbalance that allows the window to be shut and opened without the need for mechanical or electrical devices. The sash-weights are typically ignored or discarded by homeowners and turned into scrap when they fail; therefore, you may need to search for 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 require a new piece string, a length of 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. Pin punch and hammer can be used to cut off the wood pegs holding the components together. The majority of them are large on one side and smaller on the other. It is important 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 with an instrument, and then tapping the mortised area loose with a mallet.

Once the sash has been released, you can remove the sash stops and access the weight pockets. Usually, this is done through a hole near the bottom of each jamb. The hole is then covered with the wooden panel which 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 of the old sash and replace it with the new. First, weigh the sash, as the weights you have might not be the correct size. Once the new weight is installed, thread a string through the sash pulling mechanism. Then nail the string to the boxed frame, but only leave a few inches of string hanging from the head for future adjustment.

Sash Cords

In most old double-hung window the chain or cord is attached to the weights. This helps keep the sashes within the jamb balanced. Over time, these cords may become damaged and render it impossible to raise the windows. A new sash cord can restore the ability to move the sash up and down and window sash repairs hold it in place when opened.

To replace sash cords, the first step is to remove the access panels from the jambs. These are usually nailed or screwed in and must be removed or relocated. It may be possible to remove them using the hammer or chisel but it is always better to lay out dust sheets before starting any work.

After you have removed the access panel, you are able to begin working on the sash. Utilize a flat bar or chisel, to pry the narrow parting beads from their grooves. They are usually wedged in or nailed, but they can be removed which is why it's worth your time. If the sash is in place, break the mortise and tenon joints with the help of a hammer and pin or screwdriver, then unhook the wood pegs attached to the components. You should now be able to move the sash around without difficulty, though it might require lubrication if it feels stiff.

With the sash open, measure enough sash cord/chain to extend from the pulley on the top of the jamb to the sash slot on the bottom. Cut the cord or chain and fix it as described in Step 6 above. You can use either a hammer, nails, or screws. However, nails are less likely to cause damage.

If you haven't purchased an item that replaces the counterbalance system that was in place before, it is recommended to keep the original balancing weights in place. It's not too expensive to purchase them from a salvage store and they'll be easy to install once you've got the sash open. Depending on the size and shape of your window you might need to install one or two sashweights in order to keep the sash open.
