Window Sash Repairs

Sashes for windows must be inspected regularly for signs of mold, mildew and other damage. You can save future repair costs by catching these issues early on before they get out of hand.

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

Weather Stripping

Wooden window sashes can give an elegant appearance to your home. They are also sturdy and last for a long time if they are properly maintained. They may, however, get damaged or deteriorated over time due to exposure or normal wear. Sash repair specialists can restore windows back to their original condition and keep them looking great much longer than replacement windows.

Weather stripping is the primary issue to take care of when fixing windows that have sash. It is located on both the frame and the sash. If it's damaged or worn out, it can cause drafts and other issues. To fix it, start by determining the brand of your window and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Then, remove the sash and mark its width and height so that you can locate the appropriate weather stripping replacement to match.

Then, remove the sash and set it on a work surface to allow access to all four sides. If your sash has a double-hung, you'll also need to remove the weights and their accompanying ropes which should have slipped into the intended pocket in the jamb liner. Once you've taken the sash off and the weights, use a utility knife to cut away the old weather stripping at the corners, then remove it by hand or using a putty blade.

After the sash has been cleared, you can replace the parting stops. They are long pieces of wood that are used to separate the two sashes. Pam prefers standard 1/2-inch by 3/4-inch window trim from the lumberyard. But, you can also use a scrap piece of wood.

After removing the parting stop and cutting it to length and then apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty tool, and allow it to dry for at least one day. When it's completely dried and dried, apply a second coat of acrylic latex paint. This will protect the putty and give your sash a modern look.

Sash Hardware

The hardware that supports window sashes susceptible to wear and tear from the wear and tear of use and the result could be a door or window that can't be opened or closed easily. The good thing is that fixing and replacing this hardware is generally very simple and cost-effective. If a sash becomes difficult to operate you can try spraying some lubrication into the jamb channel and then open it to see if it fixes the problem. If not, window repair near me is likely with the balance of the sash and you'll have to take off the sash to access the hardware.

The ideal situation is for window sashes to swing open and closed with very little effort, but this is a difficult task if the weights become worn or if the sash meeting rail isn't properly glazed. This problem can be due to various reasons that include an absence of maintenance or an unmatched weight rating.

If the hinge arms of a window are beginning to sag, this can cause the sash to drag and eventually strike the frame in the corner that's directly opposite the hinge arm (Photo 1). To resolve this issue, first make sure the sash is firmly seated in the frame's opening and then remove it from the window. If the sash has been screwed to the hinge arm, you'll have to loosen the hinge arm and replace it (Photo 2). Next, install the new sash (Photo 3).

Because of sagging hinges and a general lack in energy efficiency, windows that are old, especially those in older homes, can be difficult to open and close. In many instances, a few minor repairs can turn these windows into smooth operation for the first time and save the homeowner money on energy bills.

It is crucial to have the tools you require before you begin. Mark the hinge channel location on the frame (Photo 1) using a pencil. This will help you to place the channel in the right place when you are finished. Take the sash off and take out all the hardware, including the beads for parting cords, chains, and cords that hold the sash in place. Soften any putty that has been hardened with the help of a heat gun set at medium and fitted with an shield for the nozzle. Remove the old sash, and keep it in a labeled bag.

Sash Weights

If your window sash repairs are to replace a damaged cord or simply to keep your windows functioning and functional, replacing worn-out weights on sash can improve sash operation and help reduce the energy cost. Sash weights are heavy lead or iron cylinders, which are enclosed inside a hidden compartment and linked to the moveable sash by a rope. They function as counterbalances, allowing you to open and shut the window without requiring mechanical or electrical devices. When they fail, sashweights tend to be ignored or disabled by homeowners.

A weight in a sash that has fallen out of the cavity is difficult to recover and you'll need to find a replacement that fits correctly. You will also require a fresh piece of string, a length sashcord and a few sashpulleys for tying the new weights to the cord.

Older wood windows are joined using mortise and tenon joints. The wood pegs holding the parts together can be removed by a pin punch and hammer. The majority of these pegs are big on one side and smaller on the other. It is essential to first remove the smaller diameter sides. Sashes that were made later in the century made use of glue instead of pegs and can be separated by cutting through the glue line using a knife, then tapping the mortised section loose with mallets.

Once the sash has been released, you can remove the stops on the sash and get access to the pockets for weights. This is typically done by drilling a small hole at the bottom of each jamb. This hole is covered by a wooden access panel that can be cut off so that you can observe the inner workings of the frame.

After you have the sash stopped and the access panel removed, you'll be able to remove the old sash weight and replace it with new. Be sure to weigh the sash prior to you do this, since the old weights may be different in size from what you require. Once the new weight has been installed, run an appropriate length of string through the pulling mechanism. Then, attach the string to the boxed frame. Leave a few inches of space at the head of the string to allow future adjustments.

Sash Cords

The majority of double-hung windows with a history have a cord or chain attached to the weights that helps keep the sashes level in the jamb. Over time, these cords could break, making it impossible to raise the window. A new sash cable will give you the ability to raise and lower the sash and ensure it stays in place when opened.


The first step to replace sash cords is to find and remove the access panels within the jambs. These are usually screwed or nailed in and must be removed. You could use a hammer or chisel for removing them however, it is always 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 pull the narrow parting beads out of their grooves. They are usually wedged in or nailed but can be prised free and it's worth your time here. If the sash remains in place, pull the mortise-and-tenon joints out with a screwdriver or hammer and then take out each wood peg. You should be able to move the sash back and forth freely, although it may require lubrication if it feels stiff.

Determine the length of sash cord/chain required to reach the sash slot on the bottom from the pulley on the top of the jamb. Cut the chain or cord and attach it in Step 6 above. You can use a hammer, nails, or screws. However, nails are less likely to cause damage.

It's best to leave the original weights if you have purchased a kit that will replace the counterbalance. They're not costly and simple to install if you purchase them at architectural salvage stores. Based on the dimensions and shape of your window you might need to install one or two sashweights in order to keep the sash open.
