Remove the sash, and mark its width and height so you can get replacement weather stripping that matches.

Next, remove the sash and set it on a table to allow access to all four sides. If your sash has been double glazing near me-hung, you must remove the weights using their ropes that should fall into the pocket in the jamb lining. Once you've removed the sash and the weights, use a utility knife to cut away the old weather stripping at the corners, and then take it off by hand or using a putty blade.

When the sash is clean it is time to replace the parting stops. These are long pieces that split the sashes. Pam prefers to use the standard 1/2-inch by 3/4 inch window trimming from the lumberyard. However, you can also use a scrap piece of wood.

After removing the stopper for the parting and cutting it to length after which, apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using your putty knife, and let it dry at least a day. When the putty is fully dried it is possible to apply a topcoat of acrylic latex.

Sash Hardware

The hardware that supports window sashes may wear out over time and with use. This could lead to a door repair; read article, or a window that is difficult to open or close.

If a sash is difficult to operate, try spraying some lubrication into the jamb channel then open it to see if it solves the issue. If not, the problem is likely with the sash balance, and you'll need to remove the sash to access the hardware.

Window sashes need to open and close with little effort. However, this may be difficult if the weights are worn out or the sash connecting rail isn't coated. This issue could be caused by a number of factors, including insufficient maintenance or an incorrect weight rating for the specific sash.

If the hinges on the window repairs begin to move, this can cause the sash drag, and then eventually to hit the frame at the opposite corner (Photo 1). To fix the problem, make sure that the sash is aligned in the frame's opening and take it off. If the sash is screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Then, put in the new sash (Photo 3).

Old windows, particularly those in older homes, may be difficult to open and close because of sagging hinges and an overall lack of energy efficiency. In many instances, a few minor repairs can turn these windows into smooth operators again and save the homeowner money on energy bills.

It is important to have the tools you need before you start. Mark the hinge channel's location on the frame (Photo 1) using pencil. This will help you get the channel back on the correct position after you've finished.

Sash Weights

Sash weights are able to be replaced to enhance the efficiency of your window sash, and also reduce the cost of energy. Sash weights consist of heavy iron or lead cylinders that are enclosed in a concealed cavity and connected by ropes to the moveable window sash. These weights function as counterbalances, which allows you to open and shut the window without requiring mechanical or electrical devices. If they fail, sashweights are usually ignored or disabled by homeowners.

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 fresh piece of string, a length sashcord and some sashpulleys to tie the new weights to the cord.

Mortise and Tenon joints can be used to join windows made of older wood. The wood pegs that hold the components together can be removed using a pin punch and hammer. The majority of them 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 utilized glue instead of pegs and can be separated by cutting the glue line with the help of a knife, and then tapping the mortised section loose using a mallet.

Once the sash has been removed, you can take off the stops on the sash and get access to the weight pockets. This is typically done by drilling an opening in the bottom of each jamb. The hole is surrounded by a wooden panel that can be removed to reveal the inside workings.

After you have the sash stopped and the access panel removed, you'll be able to take off the old sash weight and replace it with new. Make sure you weigh the sash before you begin, as the weights that were previously used may be different in size from the one you need. After the new weight is in place, tie a string to it and then thread it through the pulley for the sash. Then, you can attach the string to the boxed frame. Leave a few inches at the end of the string to allow future adjustments.

Sash Cords

Most old double-hung windows have a cord or chain attached to the weights that keeps the sashes in balance within the jamb. As time passes, these cords may break, making it impossible to raise the window. A new sash cord will give you the ability to move the sash up and down and keep it in place when opened.

To replace sash cords, the first step is to remove the access panels from the jambs. They are typically fixed or screwed in and must be removed or repositioned. It may be possible to remove them with a hammer or chisel, but it is always better to lay out dust sheets before starting any work.

Once the access panel is removed, you can begin working on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves with flat bar or chisel. They are typically wedged into or nailed but can be snipped out, door repair so it's worth taking your time here. If the sash remains in place, remove the mortise and tenon joints with pin punch and hammer or screwdriver, and then take out the wood pegs that are on each component. You should now be able to move the sash back and forth freely, although it will probably need some oil if it feels stiff.

With the sash open, measure enough sash cord/chain to extend from the pulley at the top of the jamb to the sash slot at the bottom. Cut the cord/chain and then attach it as described in the step 6 above. You can employ a hammer and screws or nails, but nails are less likely to cause damage.

It is recommended to keep the weights that came with the original counterbalance unless you've purchased a kit that will replace the counterbalance.
