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

Then, you can remove the sash from its holder, and place it on an even surface that allows you to access all four sides. If your sash has been double-hung, remove the weights with their ropes that should be buried in the jamb lining. After you have removed the sash using the utility knife, remove the weather stripping that was left by hand or using a putty blade.

After the sash has been cleaned, you can replace the parting stops. These are long pieces that separate the sashes. Pam likes to replace them with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard. However, you can also use scrap wood.

After removing the parting stop and cutting it to length after which, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty tool and let it dry for at least one day. After the putty has completely dried, you can apply a topcoat of acrylic latex. This will protect the putty, and give your sash a fresh appearance.

Then slide the sash open to see if this resolves the issue. If the issue continues it's likely to be due to the sash's balance. You'll need remove the window sash to reach this hardware.

Ideally, window sashes must be able to open and close without effort, however, this can be an issue when the weights are worn or if the sash meeting rail isn't properly glazed. This problem could be caused by many factors, including an absence of maintenance or a mismatched weight rating.

If the hinge arms on a window begin to sag this can cause the sash drag and eventually hit against the frame at the opposite corner (Photo 1). To address this problem, first ensure that the sash is firmly seated in the opening of the frame and then remove it from the window. If the sash is screwed to the hinge arm, you'll have to loosen the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).

Because of sagging hinges and a general lack in energy efficiency, old windows particularly those in older homes, can be difficult to open and close. In most cases, a few simple repairs can transform these windows into smooth operation and save homeowners money on energy costs.

In order to make these sash repairs, it's important to have all of the necessary tools in place before you begin. Begin by marking the location of the hinge channel on the frame using pencil (Photo 1). This will help you get the channel back into the correct position after you've finished.

Sash Weights

Sash weights are able to be replaced to improve the operation of your window sash, and also reduce energy costs. Sash weights consist of heavy iron or lead cylinders that are enclosed inside a concealed cavity, and are connected via ropes to the movable window sash. These weights function as counterbalances, allowing you to open and shut the window without the need for mechanical or electrical devices. If they fail, sashweights are usually neglected or not used by homeowners.

A weight in a sash that has fallen out of the cavity is difficult to retrieve and you'll need to find a replacement that fits properly. You will also require a fresh piece of string, a length of sashcord and some sashpulleys to tie the weights you are replacing to the cord.

Mortise and Tenon joints are used to join older wood windows. The wood pegs holding the parts together can be removed using the use of a pin punch and hammer. Most of these pegs have a large diameter on one side and a smaller one on the other, so it is important to remove the smaller-diameter sides first. Sashes that were made later in the century used glue instead of pegs. They can be separated by cutting the glue line with the help of a knife, and then tapping the mortised area loose using mallets.

After the sash is removed, you can take off the sash stops and access the weight pockets. Usually it is done by drilling a hole near the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the inside workings.

After the sash has been stopped and the access panel removed, you will be able to take off the old sash weight and replace it with the new. Make sure you weigh the sash before you begin, as the old weights could be different sizes than the one you need. Once the new weight has been installed, run an appropriate length of string through the pulling mechanism. Then, you can attach the string to the boxed frame. Leave a few inches at the head of the string for future adjustments.

Sash Cords

In the majority of double glazed window repair-hung windows, a chain or cord is affixed to the weights. This helps keep the sashes in the jamb in a balanced manner. Over time, these cords may become damaged and render it impossible to raise the windows. A new sash cable will restore the ability to move and lower the sash and ensure it stays in place when opened.

The first step to replace cords for sash is to locate and remove the access panels within the jambs. These are usually screwed or nailed in and need to be removed. You may be able to use a hammer and chisel to prise them off however, it is always best to lay down dust sheets before beginning any work.

After the access panel has been removed, you can start working on the sash. Make the small parting beads (also called "tie rails") out of their grooves using a chisel or flat bar. It is essential to take your time, as these are often stuck or nailed to the floor. If the sash is still in place, pull the mortise-and tenon joints 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 will probably need some oiling if it seems stiff.

Measure the length of the sash chain or sash cord required to reach the sash slot at the bottom of the pulley located at the top of the jamb. Cut the cord/chain and secure it in Step 6 above. You can employ a hammer, nail or screws, but nails are less likely to cause damage.

Unless you've bought an upgrade kit to replace the old counterbalance system, it's best to keep the original weights for balancing in place. They're not expensive and simple to install if you purchase them from salvage shops for architectural use. Depending on the size and shape of your window you might need to install one or two sashweights in order to keep it open.
