Weather Stripping
Wooden window sashes can give a classic look to your home. They are also sturdy and last for a long time provided they are properly maintained. However, they can get damaged or deteriorated over time due to exposure and normal wear. Sash repair experts can restore windows to their original state and keep them looking great longer than replacement windows.
The first step in sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. If it's loose or worn out, it can cause drafts, as well as other issues. Begin by identifying the window brand and the glass manufacturer's date (etched on the corner of the glass, or the aluminum spacers between panes). Then, remove the sash and mark its width and height so that you can locate new weather stripping that matches.
Then, take the sash from its holder, and place it on a flat surface to allow you to reach all four sides. If your sash is double-hung, you'll also need to remove the weights and their accompanying ropes that should have fallen into the pocket that was intended to be in the jamb liner. After you have removed the sash using the utility knife, you can remove the weather stripping from the old sash by hand or with the putty blade.
Once the sash has been cleaned, you can replace the stoppers that separate the two sashes. These are long pieces wood that divide the two sashes. Pam prefers standard 1/2-inch by 3/4-inch window trimming from the lumberyard. However, you can also use with a scrap piece of wood.
After removing the parting stop and trimming it to length after which, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty knife, and then let it dry for at least a day. After it has fully dried then apply a top coat of acrylic latex paint. This will protect the putty and give your sash a new look.

The good news is that repairing and replacing this hardware is typically quite simple and inexpensive. 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 this resolves the issue. If the issue persists it's likely the sash balance. You'll need to remove the window sash to get access to this part of the hardware.
Ideally, window sashes must move open and shut without effort, however, this can be a difficult task when the weights are worn or if the sash meeting rail isn't properly glazed. This issue could be caused by a number of reasons, such as insufficient maintenance or the wrong weight rating for a particular window sash.
If the hinge arms of a window begin to lose their elasticity, this could cause the sash to slide and eventually strike the frame in the corner that's opposite the hinge arm (Photo 1). To remedy the issue make sure the sash is in the proper position within the frame opening and then take it off. If the sash is secured to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).
Old windows, especially those in older homes, can be difficult to close and open due to hinges that are sagging and general lack of energy efficiency. In many cases just a few easy fixes can make these windows operate smoothly and save homeowners money on their energy bills.
It is crucial to have the tools you require before you start. Begin by marking the location of the hinge channel on the frame with a pencil (Photo 1). This will make it easier to position the channel in the right location after you've completed. Remove the sash and then remove all hardware, including the parting beads, cords, and chains that keep the sash in place. Soften any putty that has been hardened with a heat gun set to medium and fitted with a nozzle shield. Take off the old sash and put it in a bag with a label.
Sash Weights
Whether your window sash repairs are to replace a broken cord or simply to keep your windows functioning, replacing worn out weights for sash will improve its operation and reduce energy costs. Sash weights are heavy, lead or iron cylinders, which are enclosed in a concealed cavity and connected to the movable sash by a rope. These weights act as counterbalances, allowing you to open and close the window without the need for mechanical or electrical devices. When they fail, sashweights are often 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 fresh piece of string, a length sashcord and a few sashpulleys to secure the new weights to the cord.
Mortise and Tenon joints are used to join old wood windows. Hammers and pins can be used to take out the wood pegs holding the components together. The majority of these pegs are large on one side and smaller on the other. It is essential to remove first the smaller diameter sides. Later sashes made use of glue instead of pins. They can be cut with a knife and mallets.
After the sash is removed, you can remove the sash stop and gain access to the weight pocket. Usually it is done by drilling an opening in the bottom of each jamb. The hole is surrounded by a wooden panel that can be removed to reveal the inner workings.
Once the sash is stopped and the access panel is removed, you can remove the old weight and replace it. Weigh the sash first because the weights you have may not be the right size. After the new weight has been installed, thread a string through the sash pulling mechanism. Then, nail the string to the boxed frame. Leave a few inches at the head of the string to allow future adjustments.
Sash Cords
Most double-hung windows of the past come with a chain or cord attached to the weights which supports and keeps the sashes in balance in the jamb. As time passes, these cords can become damaged and make it difficult to raise windows. A new sash cord will restore the ability to move the sash upwards and downwards and hold 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 typically fixed or screwed in and will need to be removed or relocated. You may be able to use a hammer or chisel to prise them off 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 working on the sash. Utilize a flat bar, or chisel to pry the tiny parting beads from their grooves. They are typically wedged into or nailed but can be removed, so it's worth taking your time. If the sash is still in place, pull the mortise-and tenon joints with a screwdriver or hammer, then remove each wood peg. It should now be possible to move the sash around without difficulty, though it may require lubrication if it feels stiff.
Measure the length of sash chain/sash cord needed to reach the sash slot at the bottom of the pulley at the top of the jamb. Cut the chain or cord and attach it in the previous step. You can either use a hammer and nail or screws, but nails are less likely to cause damage.
It is best to keep the weights that came with the original counterbalance unless you have purchased a kit to replace the counterbalance. They're not costly and are easy to install if purchased them at architectural salvage stores. Depending on the dimensions and shape of your window, you may need to use one or two sashweights to keep it open.
