Begin by identifying the brand of window and the manufacturer's date (etched on the glass's corners, or the aluminum spacers between panes). Take the sash off, and mark its width and height so that you can find a replacement weather stripping that matches.
Then, take the sash from the holder and place it on flat surfaces to allow you to reach all four sides. If the sash is double-hung, take out the weights with their ropes that should have fallen into the pocket in the jamb lining. After removing the sash using the utility knife, take off the weather stripping that was left by hand or using a putty knife.
After the sash is cleaned, you can replace parting stops. They are long pieces of wood that are used to separate the two sashes. Pam likes to replace these with standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you can also use a piece of scrap wood.

Sash Hardware
The hardware that supports the window sashes may wear out over time and with use. This could lead to a door or a window that is difficult to open or close. It's important to know that replacing or repairing this hardware is often simple and inexpensive. If a sash isn't easy to operate try spraying grease into the jamb channel and then open it to see if that fixes the problem. If the issue continues it's likely to be due to the sash's balance. You will need to take off the window sash in order to reach this hardware.
Window sashes should be able to open and close with minimal effort. However, this could be a challenge if the weights have been worn out or the sash meeting rail is not properly covered with. This issue could be caused by a variety of factors, including insufficient maintenance or a mismatched weight rating for a particular sash.
If the hinge arms on a window begin to sag this can cause the sash drag and eventually hit against the frame in the opposite corner (Photo 1). To correct the issue make sure the sash is centered in the frame's opening and remove it. 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).
Due to sagging hinges, and a general deficiency in energy efficiency, windows that are old particularly those in older houses, could be difficult to open or close. In many cases, a few simple repairs can transform these windows into smooth operators and save homeowners money on energy bills.

Sash Weights
If your window sash repairs are to replace a broken cord or simply to keep the windows functional, replacing worn out sash weights will improve sash operation and reduce the energy cost. Sash weights are made of iron or lead cylinders that are enclosed inside a concealed cavity, and attached by a rope to the movable window sash. These weights function as counterbalances, which allows you to open and shut the window without the need for mechanical or electrical devices. The sash-weights are typically disregarded or disabled by homeowners and turned into scrap when they fail; therefore you may have to locate replacements.
It's difficult to retrieve a sash-weight that has fallen from the cavity, so you'll need to find one 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.
Older windows made of wood are joined with mortise and tenon joints. Hammers and pins can be used to remove the wood pegs that hold the parts together. The majority of these pegs are big on one side, but smaller on the other. upvc window repairs is essential to remove first the smaller diameter sides. Later sashes utilized glue instead of pins. They can be separated with a knife and mallets.
After the sash has been removed, you can remove the stopper on the sash and get access to the weight pocket. This is usually done through tiny holes at the bottom of every jamb. The hole is then covered with an access panel of wood which can be removed to allow you to see the inner workings of the frame.
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. Be sure to weigh the sash first to ensure that the weights you've got may not be the correct size. Once the new weight has been installed, you can thread a string through the sash pulling mechanism. Then, attach the string to the boxed frame. Leave a few inches of space at the head of the string to allow for future adjustments.
Sash Cords
Most double-hung windows of the past include a chain or cord attached to the weights which keeps the sashes in balance in the jamb. Over time these cords can break, making it difficult to raise the window. A new sash cord will restore the ability to move the sash up and down and hold it in place when it is 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 take them out using an axe or hammer, but it is always best to lay out dust sheets prior to 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 with flat bar or chisel. It's important to be patient as they're often placed in a wedge or nail. If the sash remains in place, pull the mortise-and tenon joints using a hammer or screwdriver, then remove each wood peg. You should be able to move the sash back and forth freely, although it might require oil if it feels stiff.
With the sash in an open position Take a measurement of the sash chain to extend from the pulley in the top of the jamb to the sash slot in the bottom. Cut the cord/chain and then secure it in Step 6 above. You can use a hammer, nails or screws. However, nails are less likely than screws 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. It's cheap to purchase them from a salvage store and they will be easy to install once you've got the sash open.
