Window Sash Repairs

Window sashes must be inspected regularly for signs of mold, mildew, and damage. If you catch these issues early you can save money on repairs in the future.

The sash is the interior frame that is vertically moved either up or down in windows that are open. This article will teach you how to do a variety of simple repairs to sash.

Weather Stripping

Wooden window sashes can add an elegant appearance to your home. here are also durable and last for a long time provided they are properly maintained. They may, however, become damaged or degraded with time due to exposure or normal wear and tear. Sash repair experts can restore windows back to their original condition and maintain their appearance longer than replacement windows.

The first step to repair sash window damage is to fix weather stripping, which can be found on both the sash as well as the frame. If it's loose or worn out, it can lead to drafts, as well as other issues. Start by identifying the window's brand and the manufacturer's date (etched on the glass's corner, or the aluminum spacers between panes). Then, remove the sash and mark its height and width, so you can find the appropriate weather stripping replacement to match.

Then, remove the sash and place it on a surface so you can access all four sides. If your sash has been double-hung, remove the weights with their ropes that should fall into the pocket in the jamb lining. Once you've removed the sash using a utility knife, you can use it to remove the old weather stripping at the corners, then remove it by hand or using a putty blade.


When window repair near me is clean it is time to replace the parting stops. These are long pieces of wood that separate the two sashes. Pam likes to replace these 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 for the parting and trimming it to length after which, apply a thin layer of glazing compound on the bottom of the sash. Smooth out the compound using your putty knife and let it dry for at least a few days. After the putty has completely cure and dried, you can apply a topcoat of acrylic latex. This will protect the putty and give your sash a fresh appearance.

Sash Hardware

The hardware that holds window sashes is susceptible to wear and tear due to age and use and the result could be a door or window that can't be opened or closed easily. It's a good idea to know that replacing and repair of this hardware is typically straightforward and cost-effective. If you are having trouble opening a sash, spray some grease into the jamb channel. Then slide the sash open to see if it resolves the problem. If not, the issue is likely with the sash balance, and you'll need to take out the sash to access this hardware.

Ideally, window sashes must move open and shut with very little effort, however, this can be a difficult task when the weights are worn or if the sash's meeting rail isn't properly coated. This can be due to various reasons that include an absence of maintenance or an unmatched weight rating.

If the hinge arms on a window begin to sag this can cause the sash drag, and then eventually to hit the frame in the opposite corner (Photo 1). To resolve this issue, first make sure the sash fits squarely in the frame's opening and then take it out of the window. If the sash has been fixed to the hinge arm, take it off the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).

Old windows, especially those in older houses, can be difficult to close and open due to hinges that are sagging and an overall lack of energy efficiency. In most instances, a few easy repairs can transform these windows into smooth operators again and save the homeowner money on energy bills.

In order to make these sash repairs it is important to have all the necessary tools in place before you begin. Begin by marking the position of the hinge channel on the frame with pencil (Photo 1). This will allow you to place the channel in the right position after you've finished. Then, remove the sash and remove the hardware including the beads that separate (Photo 2) and the cords or chains that secure it. Soften any putty that has been hardened with the help of a heat gun set at medium and equipped with an shield to block the nozzle. Remove the old sash, and put it in a bag that is labeled.

Sash Weights

No matter if your window sash repair needs are to replace a damaged cord or to keep your windows functioning, replacing worn out weights on sash can improve sash operation and help reduce energy costs. Sash weights are made of heavy iron or lead cylinders that are encased inside a concealed cavity, and connected by ropes to the movable window sash. These weights provide counterbalance which allows the window to be opened and closed without the use of electrical or mechanical devices. When they fail, sashweights tend to be neglected or not used by homeowners.

It's not easy to retrieve a sash-weight that has fallen from the cavity, so you'll want to find one that fits correctly. You will also require a new piece string, a length sashcord and a few sashpulleys to secure the weights you are replacing to the cord.

Older wood windows are joined using mortise and tenon joints. Hammers and pins can be used to cut off the wood pegs holding the parts together. The majority of them are large on one side and smaller on the other. It is essential to remove first the smaller diameter sides. Later sashes used glue instead of pins. They can be separated with a knife and mallet.

After the sash is removed, you can remove the sash stop and access the weight pocket. Usually, this is done through 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.

Once 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. Make sure you weigh the sash before you do this, as the weights that were previously used may be a different size than what you require. Once the new weight is installed, run the string through the sash pulling mechanism. Then nail the string to the boxed frame, but only leave a few inches of string sticking out from the head for future adjustment.

Sash Cords

In the majority of old double-hung windows the chain or cord is affixed to the weights. This helps keep the sashes of the jamb in a balanced manner. Over time, these cords may 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 ensure it stays in place when opened.

To replace sash cords the first step is to remove the access panels from the jambs. They are usually fixed or screwed in and must be removed or moved. You could use a hammer and chisel to remove them however, it is always best to lay down dust sheets before starting any work.

After you have removed the access panel, you are able to begin to work on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves using a chisel or flat bar. They are usually wedged in or nailed, but they can be snipped out and it's worth your time. If the sash remains in place, pry out the mortise and the tenon joints by using a hammer and pin punch or screwdriver, then unhook the wood pegs on the components. The sash should be able to move freely, however it may require some lubrication to feel less stiff.

With the sash in an open position, measure enough sash cord/chain to extend from the pulley in the top of the jamb to the sash slot in the bottom. Cut the chain or cord and secure it as in Step 6 above. You can either employ a hammer, screws or nails, however nails are less likely to cause damage.

If you don't have an item that replaces the old counterbalance system, it is recommended to keep the original balancing weights in place. They're not costly and easy to install if purchased them from architectural salvage stores. Based on the dimensions and shape of your window, you may need to use one or two sashweights to keep it open.
