If your sash has been double-hung, remove the weights using their ropes that should have fallen into the pocket in the jamb lining. Once you've removed the sash using a utility knife, you can use it to cut off the old weather stripping at the corners, then take it off by hand or using a putty blade.

After the sash has been cleared it is time to replace the parting stops. They are long pieces of wood that are used to separate the two sashes. Pam prefers to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard, however you could also use scrap wood.

After removing the stopper and cutting it to length and then apply a thin layer of glazing compound to the bottom of the sash.

If not, the issue is likely to be with the balance of the sash and you'll have to take off the sash to gain access to this hardware.

Ideally, window sashes should be able to open and close without effort, but this is difficult when the weights wear out or if the sash meeting rail isn't properly glazed. This can be due to a variety of factors that include the lack of maintenance or an unmatched weight rating.

If the hinges on the window begin to move, this can cause the sash drag and then hit the frame at the opposite corner (Photo 1). To fix the problem, make sure that the sash is centered in the frame opening and then remove it. If the sash is attached to the hinge arm, unbolt the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).

Windows that are old, especially in older homes, can be difficult to open and close, because of sagging hinges and a general inefficiency. In many cases just a few easy fixes can make these windows operate smoothly and help homeowners save money on energy bills.

Sash Weights

No matter if your window sash repair needs are to replace a damaged cord or simply to ensure that the windows are functional by replacing worn out weights on sash can improve sash operation and reduce energy consumption. Sash weights are heavy, lead or iron cylinders, which are enclosed in a concealed cavity and connected to the movable window sash using rope. They are counterbalancers which allows the window to be opened and closed without using mechanical or electrical devices. If they fail, sashweights are often neglected or not used by homeowners.

It's not easy to retrieve the sash-weight that fell from the cavity, so you'll want to find one that fits properly. You will also require a new piece of string, a length sash cord and some sash pulleys to tie the new sash weights to the sash cord.

Older windows made of wood are joined using mortise and tenon joints. The wood pegs that hold the components together can be removed with pin punches and hammers. Most of these pegs have large diameters on one side and a smaller size on the other, so it is essential to remove the smaller-diameter sides first. Sashes made later in the century made use of glue instead of pegs. They can be separated by cutting through the glue line with an instrument, and then tapping the mortised area loose with mallets.

Once the sash is freed, you can remove the stopper on the sash and get access to the weight pocket. Usually, this is done through an opening at the bottom of each jamb. The hole is surrounded by an unfinished wooden panel that can be removed to reveal the inner workings.

When the sash has been shut off and the access panel is removed, you can take off the old weight and replace it. Weigh the sash first to ensure that the weights you've got may not be the correct size. After the new weight is installed, you can thread a string through the sash pulling mechanism. Then, you can attach the string to your boxed frame. Leave a few inches at the head of the string to allow future adjustments.

Sash Cords

In most old double-hung window the chain or cord is connected to the weights. This supports and keeps the sashes of the jamb balanced. Over time, these cords can become damaged and make it difficult to raise the windows. A new sash cable can restore the ability to raise and lower the sash, and keep it in position when opened.

To replace sash cords, the first step is to remove the access panels from the jambs. They are typically screwed or nailed in and must be removed. It is possible to remove them with an axe or hammer, but it is always best to lay out dust sheets before starting any work.

After the access panel has been removed, you can begin working on the sash. Make the small parting beads (also known as "tie rails") out of their grooves with a chisel or flat bar. It is important to take your time as they're often placed in a wedge or nail. If the sash remains in place, pry the mortise-and tenon joints with a hammer or screwdriver and then take out each wood peg. The sash should move freely now, but it may require some lubrication to feel less stiff.

With the sash open Take a measurement of the sash chain to reach from the pulley on the top of the jamb to the sash slot on the bottom. Cut the cord/chain and then attach it as described in the step 6 above. You can employ a hammer and screws or nails, but nails are less likely to cause damage.

If you don't have an item that replaces the old counterbalance system it's best to keep the original balancing weights in place. They are not expensive and easy to install if you purchase them at architectural salvage stores. Depending on the size of your window, two or three sash weights could be needed to keep the sash in an open position.
