Then, take the sash from its holder, and place it on flat surfaces to allow you to reach all four sides. If your sash has been double-hung, you must remove the weights using their ropes that should have fallen into the pocket within the jamb lining. After you've removed the sash, use a utility knife to remove the old weather stripping at the corners, and then remove it manually or using a putty blade.

After the sash is cleared, you can install the parting stops. These are long pieces that split the sashes. Pam prefers to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you can also replace them with a piece of scrap wood.

This issue can be caused by a number of factors, including the lack of maintenance or a mismatched weight rating for a particular sash.

If the hinge arms of a window are beginning to slide, this could cause the sash to slide and eventually strike the frame in the corner directly opposite the hinge arm (Photo 1). To correct the issue, make sure that the sash is aligned in the frame opening and then take it off. If the sash has been fixed to the hinge arm, remove the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

Windows that are old, especially in older homes, can be difficult to open and close, because of sagging hinges and an overall lack of energy efficiency. In many instances, a few easy repairs can turn these windows into smooth operators for the first time and save the homeowner money on energy costs.

Sash Weights

Sash weights can be replaced to improve the operation of your window sash and decrease the cost of energy. Sash weights are composed of heavy iron or lead cylinders that are encased in a hidden cavity and attached by ropes to the moveable window sash. These weights provide counterbalance which allows the window to be shut and opened without the use of electrical or mechanical devices. The sash weights are usually neglected or ignored by homeowners, and are turned into scrap when they fail. Consequently you might need to locate replacements.

A weight in a sash that has fallen out of the cavity is difficult to recover and you'll need to find a new one that is suitable for the. You will also require a new piece string, a length sashcord and a few sashpulleys for tying 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 the use of a pin punch and hammer. The majority of them have large diameters on one side and a smaller one on the other, which is why it is important to remove the small-diameter sides first. 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 using an instrument, and then tapping the mortised section loose with a mallet.

Once the sash is freed, you can remove the sash stop and gain access to the weight pocket. Usually it is done by drilling an opening in the bottom of each jamb. This hole is covered with a wooden panel that can be removed to reveal the inside workings.

Once you have the sash stopped and the access panel removed, you'll be able to take off the weight from the sash and replace it with the new. Be sure to weigh the sash prior to you do this, as the weights that were previously used may be different in size from what you require. After the new weight is in place then tie a string to it and then thread it through the sash pulley. Then, you can attach the string to your boxed frame. Leave a few inches of space at the head of the string to allow future adjustments.

Sash Cords

Most old double-hung windows have a cord or chain attached to the weights that supports and keeps the sashes level within the jamb. As time passes, these cords may break, making it difficult to raise the window. A new sash cord will restore the ability to move the sash upwards and downwards and hold it in place when opened.

The first step to replace sash cords is to locate and remove the access panels within the jambs. They are usually fixed or screwed in and will require to be removed or moved. You might be able to use a hammer or chisel to remove them but it's best to lay down dust sheets prior to starting any work.

After removing the access panel, you are able to begin to work on the sash. Take the narrow beads (also known as "tie rails") out of their grooves using flat bar or chisel. It is essential to take your time because they are usually stuck or nailed to the floor. If the sash remains in place, pry out the mortise and the tenon joints by using pin punch and hammer or screwdriver, then remove the wood pegs that are on each piece. It should now be possible to move the sash around freely, though it will probably need some oiling if it seems stiff.

With the sash in an open position, measure enough sash cord/chain to reach from the pulley on the top of the jamb to the sash slot in the bottom. Cut the chain or cord and secure it as in the previous step. You can either employ a hammer and screws or nails, but nails are less likely to cause damage.

It is recommended to keep the original weights if you've purchased a kit to replace the counterbalance that was previously installed. They're not costly and are easy to install if purchased them at architectural salvage stores. Depending on the size and shape of your window, you might need to install one or two sashweights to keep it open.
