If the hinge arms of a window begin to lose their elasticity, this could cause the sash to drag and eventually strike the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To remedy the issue, make sure that the sash is in the proper position within the frame's opening and remove it. If the sash is fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2).

Sash Weights

If your window sash repairs are to replace a damaged cord or just to ensure that the windows are functional, replacing worn out weights on sash can improve sash operation and cut down on energy costs. Sash weights are heavy lead or iron cylinders that are enclosed inside a hidden compartment and connected to the movable window sash using a rope. They provide counterbalance which allows the window to be closed and opened without the need for mechanical or electrical devices. The sash weights are often disregarded or disabled by homeowners and then turned into scrap when they break; therefore, you may need to locate replacements.

It's difficult to retrieve an sash-weight which has fallen from the cavity, so you'll want to find one that fits properly. You will also require an additional piece of string, a length of the sash cord, as well as some sash pulleys that will tie the new sash weights onto the sash cord.

Older wood windows are joined by mortise and tenon joints. Pin punch and hammer can be used to take out the wood pegs holding the components together. The majority of these pegs are big on one side, but smaller on the other. It is important to first remove the smaller diameter sides. Later sashes used glue instead of pins. They can be cut by using a knife or mallet.

Once the sash has been released, you can remove sash stops and access the weight pockets. This is usually done via tiny holes in the bottom of each jamb. The hole is then covered with the wooden panel which can be removed to reveal the interior workings.

First, weigh the sash to ensure that the weights you have might not be the right size. After the new weight has been installed, you can thread an appropriate length of string through the pulling mechanism. Then nail the string to the frame, but only leave a few inches of string sticking out from the head for future adjustments.

Sash Cords

Over time these cords can break, making it difficult to raise the window. A new sash cord can restore the ability to move the sash up and down and keep it in place when opened.

After removing the access panel, you can begin working on the sash. Utilize a flat bar, or chisel to pry the tiny parting beads from their grooves. These are often wedged in or nailed, but they can be prised free and it's worth your time. If the sash remains in place, pry the mortise-and-tenon joints out 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 might require oiling if it seems stiff.

Take a measurement of the length of sash chain/sash cord required to reach the sash slot at the bottom of the pulley at the top of the jamb. Cut the chain or cord, and then secure it in the previous step. You can either employ a hammer and screws or nails, but nails are less likely to cause damage.
