Window Sash Repairs

Make sure to check the sashes of your windows regularly for signs of damage, mildew and mold. You can save future repair costs by catching these issues early, before they become too much.

The sash is an internal frame that can move up and down vertically in windows that are open. This article will teach you how to carry out a few simple repairs to the sash.

Weather Stripping

Wood window sashes give an elegant look to your home and, when properly maintained, can last for a long time. They may, however, get damaged or deteriorated over time due to exposure or normal wear. Sash repair specialists can restore windows to their original state and keep them looking great longer than replacement windows.

Weather stripping is the primary issue to take care of when fixing sash windows. It’s located on both the frame and sash. If it’s worn or loose, out, it could cause drafts and other issues. To fix it, begin by determining your window’s brand and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its height and width so that you can locate replacement weather stripping to match.

Then, remove the sash and set it on a table so that you can reach all four sides. If your sash was double-hung, take out the weights with their ropes that should be buried in the jamb lining. After removing the sash using the utility knife, take off the old weather stripping by hand or using a putty knife.

Once the sash is clear 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, but you can also replace them with a piece of scrap wood.

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

Sash Hardware

The hardware that supports window sashes susceptible to wear and tear due to the wear and tear of use and the result could be a window or door that can’t be opened or closed easily. The good news is that repairing double glazed windows and replacing this hardware is generally relatively easy and affordable. If a sash is difficult to operate, try spraying some grease into the jamb channel then slide it open to see if this fixes the problem. If the issue continues it’s likely to be due to the sash’s balance. It is necessary to remove the window sash to access the hardware.

Ideally, window sashes must be able to open and close with minimal effort however, this can be difficult when the weights wear out or if the sash meeting rail isn’t properly glazed. This problem can be caused by a number of factors, including lack of maintenance or by an incorrect weight rating for the specific sash.

If the hinge arms of a window are starting to lose their elasticity, this could cause the sash’s to drag and eventually hit the frame in the corner that’s opposite the hinge arm (Photo 1). To fix this problem, first ensure that the sash is squarely inserted into the opening of the frame 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). Install the new sash next (Photo 3).

Because of sagging hinges and a general lack of energy efficiency, old windows especially in older homes, can be difficult to open and close. In many cases, a few simple fixes can help these windows function smoothly once more and help homeowners save money on energy bills.

To complete these repairs to the sash it is essential to have all the necessary tools in place before you begin. Start by marking the location of the hinge channel on the frame using a pencil (Photo 1). This will allow you to get the channel back into place correctly when you’re finished. Then, remove the sash, and then remove the hardware including the parting beads (Photo 2) and the cords or chains which hold it in place. Soften any putty that has been hardened with a heat gun set to medium and fitted with an shield for the nozzle. Remove the old sash, and put it in a bag with a label.

Sash Weights

If your window sash repairs are to replace a broken cord or to keep the windows functional and functional, replacing worn-out sash weights will improve sash operation and cut down on the energy cost. Sash weights consist of heavy iron or lead cylinders that are enclosed in a hidden cavity and are connected via ropes to the movable window sash. These weights provide counterbalance, allowing the window to be shut and opened without the need for mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners and then turned into scrap when they fail. Consequently you may have to find replacements.

It’s not easy to retrieve the sash-weight that fell from the cavity, so you’ll want to find one that is suitable for the. You will also require a new piece of string, a length of sash cord and some sash pulleys to connect the new sash weights the sash cord.

Older windows made of wood are joined with mortise and tenon joints. Pin punch and hammer can be used to take out the wood pegs that hold the parts together. Most of these pegs have an enormous diameter on one side and a smaller size on the other, which is why it is essential to remove the smaller-diameter ones first. Sashes 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 using mallets.

Once the sash has been removed, you can take off the stops on the sash and get access to the pockets for weights. Usually this is accomplished by drilling an opening at the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the inside workings.

After the sash has been stopped and the access panel removed, you will be able to take off the weight of the old sash and replace it with the new. Be sure to weigh the sash prior to you do this, as the old weights may be different sizes than what is needed. Once the new weight is installed, tie a string to it and thread it through the pulley for the sash. Then, nail the string to your boxed frame. Leave a few inches protruding at the top of the string to allow for future adjustments.

Sash Cords

In most old double-hung window the chain or cord is attached to the weights. This helps keep the sashes of the jamb in a balanced manner. As time passes, these cords may become damaged and make it difficult to raise the windows. A new sash cable will restore the ability to move and lower the sash and keep it in position when it is opened.

To replace sash cords the first step is to remove the access panels from the jambs. These are usually nailed or screwed in and will need to be removed or repositioned. You could employ a hammer and chisel to remove them, but it’s always better to lay down dust sheets prior to commencing any work.

After removing the access panel, you are able to begin working on the sash. Make the small parting beads (also known as “tie rails”) out of their grooves using the 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 is in place, window sash repairs remove the mortise and the tenon joints by using the help of a hammer and pin or screwdriver, and then take out the wood pegs on each piece. The sash should be able to move freely, however it may require some lubrication in order to feel less stiff.

With the sash in an open position Take a measurement of the sash 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, but nails are less likely to cause damage.

It’s best to leave the original weights in place unless you have purchased a kit that will replace the counterbalance that was previously installed. They’re not expensive and easy to install if you purchase them from salvage shops for architectural use. Depending on the size of your window one or two sash weights might be required to keep it in an open position.
