Regularly inspect the window sashes for any damage, mildew and mold. By catching these problems early you will save money on future repairs.

The sash is an interior framing that moves vertically up or down in windows that are open. This article will demonstrate how to do a variety of simple sash repair.

Weather Stripping

Wooden window sashes can give a classic look to your home. They are also sturdy and can last many years if they are properly maintained. However, they can become damaged or degraded with time due to exposure or normal wear and tear. Sash repair experts can restore windows to their original state and maintain their appearance much longer than replacement windows.

The first step in repair sash windows is to address weather stripping, which can be found on both the sash and frame. It could cause drafts if damaged or is loose. To fix it, start 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). Then, remove the sash and mark its height and width, so you can find new weather stripping that matches.

Then, remove the sash from the holder and place it on an even surface that allows you to see all four sides. 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 taken the sash off, use a utility knife to cut off the old weather stripping at the corners. Then, remove it manually or with a putty knife.

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

After removing the stopper and cutting it to length, apply a thin coat of glazing compound to the bottom of the sash. Smooth the compound using your putty tool and let it dry at least a day. After the putty has completely cured and dried, you can apply a topcoat of acrylic latex. This will protect the putty, and give your sash a modern appearance.

Sash Hardware

The hardware that holds window sashes is susceptible to wear and tear from the wear and tear of use, and the result can be a door or window that isn't able to open or close easily. The good thing is that fixing and replacing this hardware is typically very simple and cost-effective. If a sash is difficult to operate try spraying oil into the jamb channel then open it to see if that fixes the problem. If not, the issue is likely with the sash balance, and you'll have to take off the sash to access the hardware.

The ideal situation is for window sashes to move open and shut with very little effort, but this can be an issue when the weights are worn or if the sash's meeting rail isn't properly glazed. This issue can be due to various reasons such as a lack of maintenance and a mismatched weight rating.

If the hinge arms of a window begin to slide, 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 remedy the issue, make sure that the sash is aligned in the frame opening and then remove it. If the sash has been screwed to the hinge arm, you'll need to remove the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).

window repairs to sagging hinges, and a general lack of energy efficiency, older windows especially in older homes, can be difficult to open or close. In many cases it is a matter of making a few minor adjustments that can make these windows operate smoothly and help homeowners save money on energy bills.

It is crucial to have the tools needed before you begin. Start by marking the location of the hinge channel on the frame with pencil (Photo 1). This will allow you to get the channel back into position correctly after you've completed. Take the sash off, and remove all the hardware, including the beads for parting cords, chains, and cords that keep the sash in place. Soften any putty that has been hardened with a heat gun set to medium and equipped with a nozzle shield. Remove the old sash and place it in a bag with a label.

Sash Weights

No matter if your window sash repair needs are to replace a damaged cord or to ensure that the windows are functional and functional, replacing worn-out weights on sash can improve sash operation and cut down on the energy cost. Sash weights consist of iron or lead cylindricals that are contained inside a concealed cavity, and connected by a rope to the movable window sash. These weights provide counterbalance which allows the window to be shut and opened without using mechanical or electrical devices. The sash weights are usually ignored or discarded by homeowners and then turned into scrap when they break; therefore, you may need to locate replacements.


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 new piece of string, a length of the sash cord, as well as some sash pulleys to connect the new sash weights the sash cord.

Mortise and Tenon joints can be used to join old wood windows. The wood pegs holding the components together can be removed by a pin punch and hammer. The majority of these pegs are big on one side, but smaller on the other. It is essential to remove first the smaller diameter sides. Sashes made later in the century made use of glue instead of pegs. They can be separated by cutting the glue line with an instrument, and then tapping the mortised area loose using mallets.

Once the sash is freed and removed, you can take off the sash stop and gain access to the weight pocket. Usually it is done by drilling a hole near the bottom of each jamb. The hole is surrounded by a wooden panel that can be removed to reveal the inner workings.

After you have the sash stopped and the access panel removed, you will be able to take off the weight from the sash and replace it with the new. Be sure to weigh the sash prior to you begin, as the old weights may be different sizes than the one you need. After the new weight is installed, you can thread the string through the sash pulling mechanism. Then, you can nail the string to the boxed frame, but leave a few inches of string protruding from the head to allow for future adjustments.

Sash Cords

In most old double-hung window the chain or cord is attached to the weights. This supports and keeps the sashes in the jamb in a balanced manner. 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.

The first step to replace sash cords is to locate and remove the access panels in the jambs. They are usually attached by nails or screws and must be removed. It may be 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. Utilize a flat bar or chisel to pry the tiny parting beads out of their grooves. It is essential to take your time because they are usually wedged or nailed in place. If the sash is still in place, pull the mortise-and tenon joints with a hammer or screwdriver and then remove each wood peg. The sash should move freely, however it might require some lubrication in order to feel less stiff.

Measure the length of the sash chain or sash cord needed to reach the sash slot on the bottom from the pulley at the top of the jamb. Cut the cord/chain, and then fix it using the previous step. You can do this with a hammer, nails or screws. However nails are less likely to cause damage.

Unless you've bought an upgrade kit to replace the counterbalance system that was in place before, it's recommended to keep the original balancing weights in place. It's cheap to purchase them from a salvage store and they will be easy to install once you have the sash opened. Depending on the size of your window one or two sashweights might be required to keep the sash in an open position.
