Window Sash Repairs

Regularly inspect the window sashes for any damage, mildew and mold. You can save future repair costs by catching these issues in the early stages before they become out of control.

The sash is an interior framing that can be moved vertically up or down in windows that are open. This article will show you how to perform several simple sash repair.

Weather Stripping

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

The first step for sash window repair s is addressing weather stripping, which is found on both the sash as well as the frame. It can cause drafts if worn out or loose. To fix it, start by determining the brand of your window and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Remove the sash and mark its size and width so that you can purchase new weather stripping that is compatible with the original.


Then, take it off and place it on a surface so you can access all four sides. If the sash is double-hung, you'll have to remove the weights as well as the ropes that go with them that should have fallen into the pocket that was intended to be in the jamb liner. After you've removed the sash and the weights, use a utility knife to cut off the weather stripping from the corners. Then, take it off by hand or using a putty knife.

Once the sash has been cleared, you can install the stoppers that separate the two sashes. These are long pieces that separate the sashes. Pam prefers standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. However, you can substitute for a scrap piece of lumber.

After removing the stopper and trimming it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth out the compound using your putty knife, then let it dry for at least a few days. When it's completely dried then apply a top coat of acrylic latex paint. This will protect the putty and give your sash a fresh appearance.

Sash Hardware

The hardware that supports window sashes can wear out with time and use. This can result in windows or doors that is difficult to open or close. It's a good idea to know that replacing or repairing this hardware is often simple and inexpensive. If you are having trouble opening a sash, spray some lubricant into the jamb channel. Then, slide the sash up and open to see if that fixes the problem. If the issue persists it's most likely that the sash balance is off. You will need to remove the window sash to get access to this part of the hardware.

The ideal situation is for window sashes to move open and shut with minimal effort however, this can be difficult when the weights wear out or if the sash that joins rail isn't properly coated. This issue could be caused by a variety of factors, including insufficient maintenance or a mismatched weight rating for a particular sash.

If the hinges on the window begin to move, this could cause the sash to drag and then hit the frame at the opposite corner (Photo 1). To resolve this problem, first ensure that the sash is squarely inserted into the opening of the frame and then remove it from the window. If the sash is screwed to the hinge arm, you'll need to loosen the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).

Due to sagging hinges, and a general lack in energy efficiency, older windows especially in older homes, can be difficult to open and close. In most instances, a few minor repairs can transform these windows into smooth operation for the first time and save the homeowner cash on energy costs.

To complete these repairs to the sash, it's important to have all of the tools needed before you begin. Mark the hinge channel location on the frame (Photo 1) with a pencil. This will allow you to get the channel back into place correctly when you're finished. Then, remove the sash and remove the hardware including the beads that separate (Photo 2) and the chains or cords which hold it in place. Soften any putty that has been hardened with an electric heat gun set to medium and fitted with a shield for the nozzle. Take off the old sash and keep it in a labeled bag.

Sash Weights

Sash weights are able to be replaced to improve the operation of your window sash and decrease energy costs. Sash weights consist of heavy iron or lead cylinders that are enclosed inside a concealed cavity, and are connected via a rope to the movable window sash. These weights function as counterbalances, allowing you to open and close the window without requiring mechanical or electrical devices. The sash-weights are typically ignored or discarded by homeowners and turned into scrap when they fail. Consequently you may have to find replacements.

A weight from a sash that fell out of the cavity is difficult to retrieve and you'll need to find a replacement that fits properly. You will also require a new piece of string, a length of sashcord and a few sashpulleys for tying the new weights to the cord.

Older wood windows are joined by mortise and tenon joints. Hammers and pins can be used to take out the wood pegs holding the parts together. The majority of them have large diameters on one side and a smaller one on the other side, so it is essential to remove the smaller-diameter ones first. Later sashes made use of glue instead of pins. They can be separated by using a knife and a mallet.

After the sash has been removed then you can take out the stopper on the sash and get access to the weight pocket. Usually this is accomplished by drilling an opening at the bottom of each jamb. The hole is surrounded by a wooden panel that can be removed to reveal the inside workings.

When the sash has been shut off and the access panel is removed, you can take off the old weight and replace it. Weigh the sash first, as the weights you have might not be the correct size. Once the new weight has been installed, you can thread the string through the sash pulling mechanism. Then nail the string to the frame, leaving a few inches of string hanging from the head for future adjustment.

Sash Cords

In the majority of double-hung windows, a chain or cord is attached to the weights. This supports and keeps the sashes of the jamb in a balanced manner. As time passes, these cords may break, making it impossible to raise the window. A new sash cable will restore the ability to move and lower the sash, and ensure it stays in place when it is opened.

To replace sash cords the first step is to remove the access panels from the jambs. They are typically nailed or screwed in and will require to be removed or relocated. It is possible to take them out using the hammer or chisel however, it is best to lay out dust sheets before beginning any work.

Once the access panel is removed, you can start working on the sash. Utilize a flat bar, or chisel to pull the narrow parting beads from their grooves. These are often wedged in or nailed in, but they can be removed, so it's worth taking your time. If the sash is in place, pry out the mortise and tenon joints using a hammer and pin punch or screwdriver, then remove the wood pegs that are on each piece. The sash should move around freely now, however it might require some lubrication to make it feel less stiff.

Take a measurement of the length of sash cord/chain needed to reach the sash slot on the bottom of the pulley at the top of the jamb. Cut the cord/chain and then attach 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.

If you don't have an item that replaces the old counterbalance system, it is recommended to keep the original balancing weights in place. It's not too expensive to purchase these from salvage shops for architectural purposes and they'll be simple to install once you have the sash opened. Based on the size of your window two or three sash weights may be needed to keep it in an open position.
