Then, take the sash off and mark its height and width, so you can find replacement weather stripping to match.
Then, take it off and set it on a surface to allow access to all four sides. If your sash is double-hung, you'll have to take off the weights and the ropes that go with them, which should have fallen into the pocket of the jamb liner. Once you've taken the sash off and the weights, use a utility knife to remove the weather stripping from the corners, then take it off by hand or using a putty knife.
Once the sash has been cleared, you can install parting stops. These are long pieces of wood that separate the two sashes. Pam likes to replace them with standard 1/2-inch-by 3/4-inch upvc window repairs trim from the lumberyard, however you can also replace them with scrap wood.
After removing the stoppers for parting and trimming them to your desired length, apply a thin layer of glazing compound to the bottom of the sash. Smooth it out using your putty knife, then let it dry for a minimum of a day. Once the putty has fully cure, you can apply an acrylic latex topcoat. This coating will protect the putty and give your sash a new appearance.
Sash Hardware

Sashes for windows should be able to open and close without much effort. However, this may be a challenge if the weights have been worn out or the sash connecting rail isn't coated. This problem can be caused by a variety of reasons, such as the lack of maintenance or the wrong weight rating for the particular window sash.
If the hinge arms of a window are beginning to sag, this can cause the sash to drag and eventually hit the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To remedy the issue make sure the sash is in the proper position within the frame opening and then remove it. If the sash is screwed to the hinge arm, you'll need to loosen the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).
Due to sagging hinges, and a general lack of energy efficiency, old windows especially in older homes, may be difficult to open or close. Sometimes it is a matter of making a few minor adjustments that can allow these windows to operate smoothly again and save homeowners money on their energy bills.
It is crucial to have the tools needed before you start. Begin by marking the location of the hinge channel on the frame using a pencil (Photo 1). This will help you get the channel back into place correctly when you're finished.

Sash Weights
Whether your window sash repairs are to replace a broken cord or to keep your windows functioning, replacing worn out sash weights will improve sash operation and help reduce energy consumption. Sash weights are made of iron or lead cylinders that are encased in a concealed cavity and connected by ropes to the moveable window sash. They provide counterbalance, allowing the window to be shut and opened without the need for mechanical or electrical devices. When they fail, sashweights are usually ignored or disabled by homeowners.
It is difficult to recover the sash-weight that fell from the cavity, so you'll need to find one that fits properly. You will also require a new piece of string, a length of the sash cord, as well as some sash pulleys to tie the new sash weights to the sash cord.
Older wood windows are joined with mortise and tenon joints. The wood pegs holding the components together can be removed by a pin punch and hammer. The majority of these pegs have large diameters on one side and a smaller size on the other side, so it is crucial to take out the smaller-diameter sides first. Later sashes utilized glue instead of pins. They can be cut with a knife and mallet.
After the sash is removed, you can take off the sash stops and gain access to the pockets for weights. This is typically done by drilling tiny holes at the bottom of every jamb. This hole is covered by an access panel made of wood that can be ripped off to allow you to observe the inner workings of the frame.
Once the sash is stopped and the access panel has been removed, you can take off the weight you used and replace it. Be sure to weigh the sash before you do this, as the old weights could be a different size than what is needed. After the new weight is installed, you can thread an appropriate length of string through the pulling mechanism. Then attach the string to the boxed frame, but only leave a few inches of string protruding from the head for future adjustment.
Sash Cords
In the majority of double-hung windows, a chain or cord is connected to the weights. This keeps the sashes within the jamb in a balanced manner. Over time, these cords can become damaged and render it impossible to raise windows. A new sash cord will give you the ability to move the sash upwards and downwards and keep it in position when it is opened.
To replace sash cords the first step is to remove the access panels from the jambs. They are usually fixed or screwed in and will require to be removed or repositioned. You may be able to use a hammer or chisel to remove them, but it's always better to lay down dust sheets prior to commencing any work.

They are typically wedged into or nailed, but they can be removed and it's worth your time here. If the sash remains in place, remove the mortise and tenon joints with the help of a hammer and pin or screwdriver, and then take out the wood pegs on the components. It should now be possible to move the sash back and forth freely, although it may require oiling if it seems stiff.
With the sash in an open position With the sash in an open position, measure the sash chain or cord to extend from the pulley at the top of the jamb to the sash slot on the bottom.
