Window Sash Repairs

Check the windows sashes regularly for any damage, mildew and mold. If you catch these issues early you can save money on repairs in the future.

The sash is an interior frame that is able to move up and down vertically in windows that are open. This article will show you how to make several simple sash repairs.

Weather Stripping


Wood window sashes add a classic aesthetic to your home. When properly maintained, can last for a long time. They may, however, be damaged or degraded over time due to exposure or normal wear. Sash repair specialists can restore windows to their original state and maintain their appearance longer than replacement windows.

The first step for sash window repairs is addressing weather stripping, which is found on both the sash and frame. It can cause drafts if it's worn or loose. Start by identifying the window's brand and the date of manufacture for the glass (etched on the corner of the glass or the aluminum spacers between panes). Then, remove the sash and mark its height and width, so you can find new weather stripping that matches.

Then, take it off and place it on a work surface so you can access all four sides. If the sash is double-hung, take out the weights using their ropes that should be buried in the jamb lining. Once you've removed the sash and the weights, use a utility knife to cut away the weather stripping that was formerly in place at the corners, then remove it by hand or using a putty knife.

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

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

Sash Hardware

The hardware that holds window sashes is prone to wearing out from age and use, and the result can be a door or window that isn't able to open or close easily. It's good to know that replacing or fixing this hardware is usually easy and affordable. If a sash is difficult to operate, try spraying some oil into the jamb channel then open it to see if it resolves the issue. If the problem persists it's likely that the sash balance is off. You'll need to remove the window sash to get access to this part of the hardware.

Sashes for windows should be able to open and close without much effort. However, this may be difficult if the weights are worn out or the sash-to-rail meeting rail is not properly covered with. linked site can be due to a variety of factors, including a lack of maintenance and a mismatched weight rating.

If the hinge arms of a window are beginning to slide, this could cause the sash to drag and eventually strike the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To address this problem, first ensure that the sash fits squarely in the frame's opening and then take it out of the window. If the sash is screwed to the hinge arm, you'll have to remove the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).

Due to hinges that are sagging, and a general lack in energy efficiency, windows that are old, especially those in older homes, can be difficult to open and close. In most instances, a few easy repairs can turn these windows into smooth operators again and save the homeowner cash on energy costs.

It is important to have the tools you require before you begin. Begin by marking the location of the hinge channel on the frame with pencil (Photo 1). This will allow you to place the channel in the correct place when you are finished. Take the sash off and then remove all hardware, including the beads for parting, cords, and chains that keep the sash in place. Soften any hardened putty with an electric heat gun set to medium and fitted with a shield to block the nozzle. Remove the old sash, and place it in a bag that is labeled.

Sash Weights

Sash weights can be replaced to enhance the efficiency of your window sash and reduce the cost of energy. Sash weights are made of iron or lead cylinders that are enclosed in a hidden cavity and are connected via ropes to the moveable window sash. They provide counterbalance which allows the window to be opened and closed without the need for mechanical or electrical devices. The sash weights are usually disregarded or disabled by homeowners and turned into scrap when they fail; therefore you may have to find replacements.

A sash weight that has fallen out of the cavity is difficult to get back It is therefore important to find a replacement that fits properly. You will also need 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.

Older windows made of wood are joined with mortise and tenon joints. Hammers and pins can be used to cut off the wood pegs that hold the parts together. The majority of these pegs are large on one side, but smaller on the other. It is crucial to first remove the smaller diameter sides. Sashes made later in the century used glue instead of pegs. They can be separated by cutting through the glue line using the help of a knife, and then tapping the mortised area loose using mallets.

After the sash is released, you can remove sash stops and access the weight pockets. Usually it is done by drilling an opening in the bottom of each jamb. The hole is then covered with a wooden panel that can be removed to reveal the inner workings.

Once the sash is stopped and the access panel is removed, you are able to remove the old weight and replace it. Be sure to weigh the sash prior to you do this, as the weights that were previously used may be different sizes than the one you need. Once the new weight is installed, thread the string through the sash pulling mechanism. Then attach the string to the boxed frame, leaving a few inches of string protruding from the head for future adjustments.

Sash Cords

The majority of double-hung windows with a history have a cord or chain attached to the weights that keeps the sashes balanced in the jamb. Over time, these cords could break, making it difficult to raise the window. A new sash cable can restore the ability to move and lower the sash, and keep it in place when opened.

To replace sash cords, the first step is to remove the access panels from the jambs. They are usually nailed or screwed in and must be removed or repositioned. It may be possible to take them out using a hammer or chisel, but it is always best to lay out dust sheets before beginning any work.

After removing the access panel, you can begin working on the sash. Make the small parting beads (also called "tie rails") out of their grooves with the chisel or flat bar. These are often wedged in or nailed but can be snipped out and it's worth your time here. If the sash is still in place, remove the mortise and tenon joints using a hammer and pin punch or screwdriver, then unhook the wood pegs that are on each component. You should be able to move the sash around freely, although it might require oil if it feels stiff.

Determine the length of sash chain/sash cord required to reach the sash slot at the bottom, and the pulley located at the top of the jamb. Cut the chain or cord and secure it as in the previous step. You can use a hammer, nails, or screws. However nails are less likely than screws to cause damage.

It is recommended to keep the weights that came with the original counterbalance unless you've purchased a kit to replace the counterbalance that was previously installed. They are not expensive and are easy to install if you purchase them at architectural salvage stores. Based on the size of your window, two or three sash weights might be required to keep it open.
