Remove the sash and mark its width and height so you can get new weather stripping that is compatible with the original.

Then, remove the sash and place it on a surface so you can access all four sides. If your sash was double glazed windows repair-hung, remove the weights using their ropes that should fall into the pocket within the jamb lining. After removing the sash using the utility knife, take off the old weather stripping by hand or using a putty knife.

After removing the parting stops and cutting them to the desired length, apply a thin layer of glazing compound to the bottom of the sash. Smooth out the compound using your putty knife, then let it dry for a minimum of a day. When it's completely dried, apply a top coat of acrylic latex paint.

Sash Hardware

The hardware that supports window sashes is susceptible to wear and tear due to time and usage, and the result can be a window or door that can't be opened or closed easily.

This problem can be caused by a variety of reasons, such as lack of maintenance or by an incorrect weight rating for a particular window sash.

If the hinge arms of a window begin to lose their elasticity, this could cause the sash to slide and eventually hit the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To address this issue, first make sure the sash is firmly seated in the frame's opening and then remove it from the window. If the sash is screwed to the hinge arm, you'll have to remove the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).

Because of sagging hinges and a general deficiency 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 again and save the homeowner money on energy costs.

It is crucial to have the tools you need before you begin. Begin by marking the position of the hinge channel on the frame with pencil (Photo 1). This will allow you to get the channel back into the correct position after you've finished. Remove the sash, and then remove the hardware including the beads that separate (Photo 2) and the chains or cords which hold it in place.

Sash Weights

Whether your window sash repairs are to replace a broken cord or simply to ensure that the windows are functional, replacing worn out weights for sash will improve its operation and reduce the energy cost. Sash weights consist of iron or lead cylindricals that are contained inside a concealed cavity, and are connected via ropes to the movable window sash. They provide counterbalance, allowing the window to be closed and opened without the use of electrical or mechanical devices. The sash-weights are typically neglected or ignored by homeowners and turned into scrap when they fail. Consequently you may have to locate replacements.

It is difficult to recover a sash-weight that has fallen 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 for tying the new weights to the cord.

Older windows made of wood are joined using mortise and tenon joints. Pin punch and hammer can be used to cut off the wood pegs holding the components together. Most of these pegs have a large diameter on one side and a smaller size on the other side, so it is important to remove the smaller-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 with a knife, then tapping the mortised section loose using mallets.

After the sash has been removed and removed, you can take off the stopper on the sash and get access to the weight pocket. Usually this is accomplished by drilling an opening in the bottom of each jamb. The hole is then covered with a wooden access panel that can be ripped off to allow you to see the inner workings of the frame.

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 new. Make sure you weigh the sash prior to you begin, as the old weights could be a different size than the one you need. After the new weight is installed you can tie a string around it and thread it through the pulley of the sash. Then, you can nail the string to the frame, but only leave a few inches of string protruding from the head for future adjustment.

Sash Cords

In most old double-hung window, a cord or chain is attached to the weights. This supports and keeps the sashes of the jamb in a balanced manner. Over time, these chains can get damaged and make it difficult to raise windows. A new sash window Repair cable can restore the ability to raise and lower the sash 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 screwed or nailed into and require removal. You may be able to use a hammer and chisel to remove them, but it's always better to lay down dust sheets before starting any work.

After you have removed the access panel, you can begin to work on the sash. Make the small parting beads (also known as "tie rails") out of their grooves with the chisel or flat bar. It is essential to be patient because they are usually placed in a wedge or nail. If the sash is still in place, break the mortise and tenon joints with pin punch and hammer or screwdriver, and then take out the wood pegs on each piece. You should now be able to move the sash around without difficulty, though it might require lubrication if it feels stiff.

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