Window Sash Repairs

Check the windows sashes regularly for signs of damage, mildew and mold. You can reduce future repair costs by catching these issues early, before they become too much.

The sash is the interior framing that moves vertically upwards or downwards in windows that are open. This article will show you how to do simple sash repairs.

Weather Stripping

Wood window sashes provide a classic aesthetic to your home and, when properly maintained, they will last for many years. They can, however, become damaged or degraded with time due to exposure or normal wear. Sash repair experts can restore windows back to their original condition and maintain their appearance much 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 damaged or worn out, it can lead to drafts and other problems. Start by identifying the window repairs's brand and the date of manufacture for the glass (etched on the glass's corner or on the aluminum spacers between panes). Remove the sash and mark its width and height so you can purchase new weather stripping that is compatible with the original.

Next, remove the sash and set it on a table to allow access to all four sides. If the sash is double-hung, you'll also need to remove the weights as well as their ropes which should have slipped into the intended pocket in the jamb liner. After removing the sash using the utility knife, take off the weather stripping that was left by hand or using a putty knife.

Once the sash is clear it is time to replace the parting stops. These are long pieces wood that divide the two sashes. Pam prefers to replace them with standard 1/2-inch-by 3/4-inch upvc window repair trim from the lumberyard. However, you could also use scrap wood.

After removing the stoppers for parting and trimming them to the desired length and thickness, apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using a putty knife, and let it dry for at least a day. When it's completely dried then apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a new appearance.

Sash Hardware

The hardware that holds the windows sashes can become worn out over time and with use. This could lead to the window or door that is difficult to open or close. It's a good idea to know that replacing or fixing this hardware is usually straightforward and cost-effective. If a sash is difficult to operate, try spraying some lubrication into the jamb channel then open it to see if that solves the issue. If the issue continues it's likely the sash balance. It is necessary to remove the window sash to access the hardware.

Window sashes need to open and close with little effort. However, this can be a challenge if the weights have been worn out or the sash-to-rail connecting rail isn't properly covered with. This problem can be caused by a number of reasons, such as the lack of maintenance or the wrong weight rating for the specific window sash.

If the hinge arms on a window begin to sag this can cause the sash drag and then hit the frame at the opposite corner (Photo 1). To correct the issue ensure that the sash is aligned in the frame opening, and then take it off. If the sash is attached to the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

Because of sagging hinges and a general deficiency in energy efficiency, old windows particularly those in older houses, could be difficult to open or close. In many instances, a few minor repairs can transform these windows into smooth operators for the first time and save the homeowner money on energy bills.

To make these repairs to the sash, it's important to have all of the necessary tools in place before you begin. Begin by marking the location of the hinge channel on the frame with a pencil (Photo 1). This will allow you to position the channel in the proper place when you are finished. Remove the sash, and remove all the hardware including the parting beads, cords, and chains that hold the sash in place. The nozzle shield of the heat gun and a medium setting can soften any putty that has been hardened. Remove the old sash, and store it in an bag with a label.

Sash Weights

If your window sash repairs are to replace a broken cord or simply to keep your windows functioning by replacing worn out weights on sash can improve sash operation and help reduce energy consumption. Sash weights are hefty lead or iron cylinders that are enclosed in a hidden cavity and attached to the movable sash by a rope. These weights act as counterbalances and allow you to open and close the window without requiring mechanical or electrical devices. The sash-weights are typically neglected or ignored by homeowners and then turned into scrap when they fail; therefore you may have to search for replacements.

It's difficult to retrieve the sash-weight that fell from the cavity, so you'll want to find one that fits properly. You will also require a fresh piece of string, a length sashcord and a few sashpulleys for tying the weights you are replacing to the cord.

Older wood windows are joined by mortise and tenon joints. Pin punch and hammer can be used to remove the wood pegs that hold the parts together. The majority of them are large on one side, and smaller on the other. It is crucial to first remove the smaller diameter sides. Sashes that were made later in the century used glue instead of pegs and can be separated by cutting the glue line using an instrument, and then tapping the mortised part loose with mallets.

After the sash has been 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. This hole is covered by an access panel of wood that can be cut off to let you see the inner workings of the frame.

When the sash has been shut off and the access panel is removed, you can remove the weight that was previously installed and replace it. Be sure to weigh the sash first, as the weights you've got may not be of the right size. Once the new weight is installed, tie a string to it and thread it through the pulley of the sash. Then, nail the string to your boxed frame. Leave a few inches protruding at the head of the string to allow future adjustments.

Sash Cords

In the majority of old double-hung windows, a cord or chain is affixed to the weights. This keeps the sashes in the jamb level. Over time, these cords could break, making it difficult to raise the window. A new sash cord will restore the ability to move the sash up and down and keep it in place when opened.

The first step in replacing sash cords is to find and remove the access panels within the jambs. They are typically screwed or nailed into and need to be removed. It is possible to remove them with a hammer or chisel, but it is always best to lay out dust sheets before starting any work.

Once the access panel is removed, you can begin working on the sash. Utilize a flat bar or chisel to pry the narrow parting beads from their grooves. It's important to take your time, as these are often stuck or nailed to the floor. If the sash is still in place, pry out the mortise and tenon joints using pin punch and hammer or screwdriver, and then take out the wood pegs on each component. The sash should be able to move around freely now, however it may require some lubrication to make it feel less stiff.

With the sash in an open position, measure enough sash cord/chain to reach from the pulley on the top of the jamb to the sash slot on the bottom. Cut the cord or chain and then secure it in Step 6 above. You can do this with a hammer, nails, or screws. However nails are less likely than screws to cause damage.

It is recommended to keep the original weights if you've purchased a kit to replace the counterbalance that was previously installed. It's not too expensive to purchase them from architectural salvage stores and they'll be easy to install once you've got the sash open. Depending on the dimensions and shape of your window repairs near me, you may need to use one or two sashweights to keep it open.
