To fix it, begin by determining the brand of your window and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Take the sash off, and mark its width and height so you can purchase replacement weather stripping that matches.
Then, take the sash from its holder, and place it on flat surfaces to allow you to reach all four sides. If your sash is double-hung, you’ll have to remove the weights as well as their ropes which should have slipped into the pocket of the jamb liner. Once you’ve removed the sash and the weights, use a utility knife to cut off the weather stripping that was formerly in place at the corners, and then remove it manually or with a putty knife.
Once the sash has been cleaned, you can replace the stoppers that separate the two sashes. These are long pieces that split the sashes. Pam prefers to replace them with standard 1/2-inch-by – 3/4-inch window trim from the lumberyard, however you can also use a piece of 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.

This will protect the putty and give your sash a new appearance.
Sash Hardware
The hardware that supports window sashes is prone to wearing out from age and use, and the result can be a window or door that isn’t able to open or close easily. The good news is that repairing and replacing this hardware is typically relatively easy and affordable. If you’re having difficulty opening a sash, spray some lubricant into the jamb channel. Then slide the sash up and open to see if that fixes the issue. If the problem persists, it is most likely to be due to the sash’s balance. It is necessary remove the window sash to get access to this part of the hardware.
Ideally, window sashes must move open and shut with very little effort, but this can be an issue if the weights become worn or if the sash meeting rail isn’t properly coated. This problem can be caused by a number of factors, including insufficient maintenance or an incorrect weight rating for a particular sash.
If the hinge arms of a window begin to lose their elasticity, this could cause the sash to drag and eventually land on the frame in the corner that’s directly opposite the hinge arm (Photo 1). To address this problem, first ensure that the sash fits squarely in the frame’s opening and then take it out of the window. If the sash was fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2). Then, put in the new sash (Photo 3).
Because of sagging hinges and a general lack in energy efficiency, old windows, especially those in older homes, can be difficult to open and close. Sometimes just a few easy fixes can help these windows function smoothly and save homeowners money on energy costs.
It is essential to have the tools you require before you start. Mark the hinge channel’s location on the frame (Photo 1) with a pencil. This will allow you to get the channel back on the correct position after you’ve finished. Remove the sash and then remove all hardware, including the beads for parting cords, chains, and cords that hold the sash in place. The nozzle shield of the heat gun and medium setting will soften any hardened putty. Remove the old sash, and put it in a labeled bag.
Sash Weights
Whether your window sash repairs are to replace a damaged cord or to keep the windows functional, replacing worn out sash weights will improve sash operation and help reduce energy costs. Sash weights are made of heavy iron or lead cylindricals that are contained inside a concealed cavity, and connected by ropes to the movable window sash. These weights function as counterbalances and allow you to open and shut the window without the need for mechanical or electrical devices. The sash weights are usually ignored or discarded by homeowners and turned into scrap when they fail; therefore you might need to search for replacements.
A weight from a sash that fell out of the cavity is difficult to get back, so you will want to find a new one that is suitable for the. You will also require a new piece of string, a length sashcord and some sashpulleys to tie the weights you are replacing to the cord.
Mortise and Tenon joints can be used to join old wood windows. Pin punch and hammer can be used to cut off the wood pegs that hold the components together. Most of them have large diameters on one side and a smaller one on the other, so it is important to remove the small-diameter sides first. Later sashes used glue instead of pins. They can be cut with a knife and mallets.
Once the sash is freed then you can take out the sash stop and gain access to the weight pocket. This is typically done by drilling a small hole at the bottom of each jamb. This hole is covered with an unfinished wooden panel that can be removed to reveal the interior workings.
After you have the sash stopped and the access panel removed, you’ll be able to take off the weight from the sash and replace it with new. Be sure to weigh the sash prior to you do this, as the weights that were previously used may be a different size than the one you need. After the new weight is installed, you can thread an appropriate length of string through the pulling mechanism. Then, nail the string to the boxed frame. Leave a few inches at the end of the string to allow for future adjustments.
Sash Cords
In most old double-hung window, a chain or cord is connected to the weights. This helps keep the sashes in the jamb level. Over time these cords can break, making it impossible to raise the window. A new sash cable will give you 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. These are usually installed by screws or nails and must be removed or relocated. You may be able to use a hammer and chisel to remove them but it’s best to lay down dust sheets prior to beginning any work.
After you have removed the access panel, you are able to 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. These are often wedged in or nailed, but they can be removed, so it’s worth taking your time. If the sash is still in place, break the mortise and the tenon joints by using pin punch and hammer or screwdriver, and then take out the wood pegs attached to the components. The sash should be able to move freely now, but it may need some lubrication to feel less stiff.
Take a measurement of the length of sash chain/sash cord needed to reach the sash slot on the bottom of the pulley at the top of the jamb. Cut the cord/chain and then fix it as described in the previous step. You can employ a hammer and screws or nails, however nails are less likely to cause damage.
It’s best to leave the original weights if you’ve purchased a kit that will replace the old counterbalance. It’s cheap to purchase them from a salvage store and they’ll be easy to install once you’ve got the sash unlocked.
