Window Sash Repairs

Sashes for windows must be checked regularly for mold, mildew, and damage. You can save the cost of repairs in the future by catching the issues early before they get out of hand.

The sash is an internal frame that moves vertically up and down in windows that open. This article will teach you how to make several simple repairs to sash.

Weather Stripping

Wood window sashes give a classic aesthetic to your home and, when properly maintained, they can last for years. They may, however, become damaged or degraded with time due to exposure and normal wear. Sash repair experts can restore windows to their original state and maintain their appearance longer than replacement windows.

The first step to sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. If it's loose or worn out, it can lead to drafts and other problems. Start by identifying the window brand and the glass manufacturer's date (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 the appropriate weather stripping replacement to match.

Then, take the sash from its holder and place it on a flat surface to allow you to see all four sides. If the sash is double-hung, take out the ropes and weights that should have fallen into the pocket inside the jamb lining. Once you've taken the sash off using a utility knife, you can use it to cut away the old weather stripping at the corners, then remove it manually or window repair using a putty blade.

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

After removing the stopper and cutting it to length, apply a thin coat of glazing compound on the bottom of the sash. Smooth the compound using your putty knife, and let it dry for at least one day. After the putty has completely dried and dried, you can apply an acrylic latex topcoat. This will protect the putty and give your sash an updated look.

Sash Hardware

The hardware that supports window sashes prone to wearing out from time and usage and the result could be a door repair or window that won't open or close easily. It's important to know that replacing or repair of this hardware is typically straightforward and cost-effective. If a sash isn't easy to operate try spraying oil into the jamb channel, and then slide it open to see if that resolves the issue. If the issue persists it's likely to be due to the sash's balance. You will need to take off the window sash in order to access the hardware.

Window sashes should open and close with little effort. However, this may be difficult if weights are worn out or the sash meeting rail is not properly coated. This issue could be caused by a number of things, such as the lack of maintenance or the wrong weight rating for the specific sash.

If the hinge arms on windows begin to slide, this could cause the sash to drag and then hit the frame at the opposite corner (Photo 1). To fix the problem make sure the sash is in the proper position within the frame opening, and then take it off. If the sash has been attached to the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

Due to hinges that are sagging, and a general deficiency in energy efficiency, windows that are old particularly those in older houses, could be difficult to open and close. Many times just a few easy fixes can make these windows operate smoothly once more and help homeowners save money on energy bills.

To complete these sash repairs it is important to have all the necessary tools lined up before you begin. Start by marking the location of the hinge channel on the frame using pencil (Photo 1). This will allow you to place the channel in the right position after you've finished. Remove the sash, and remove all the hardware, including the beads for parting, cords, and chains that help to hold the sash. Soften any hardened putty using the help of a heat gun set at medium and equipped with an shield to block the nozzle. Remove the old sash, and store it in a bag with a label.

Sash Weights

Sash weights are able to be replaced to improve the operation of your window sash and reduce the energy cost. Sash weights are heavy lead or iron cylinders enclosed in a hidden cavity and connected to the movable sash by rope. They provide counterbalance which allows the window to be closed and opened without using mechanical or electrical devices. The sash-weights are typically neglected or ignored by homeowners and turned into scrap when they break; therefore you may have to find replacements.

It's not easy to retrieve an sash-weight which has fallen from the cavity, so you'll want to find one that is suitable for the. You will also need a new piece of string, a length of sash cord, and a few sash pulleys that will tie the new sash weights to the sash cord.

Older wood windows are joined with mortise and tenon joints. The wood pegs that hold the components together can be removed using a pin punch and hammer. The majority of these pegs are big 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 made use of glue instead of pegs. They can be separated by cutting through the glue line with a knife, then tapping the mortised part loose using mallets.

After the sash is removed, you can take off the sash stops and access the weight pockets. Usually, this is done through an opening in the bottom of each jamb. The hole is then covered with an unfinished wooden panel that can be removed to reveal the inside workings.

After the sash has been stopped and the access panel removed, you'll be able to take off the old sash weight and replace it with the new. Be sure to weigh the sash prior to you do this, since the weights that were previously used may be a different size than what is needed. Once the new weight is installed, tie a string to it and then thread it through the sash pulley. Then, you can attach the string to your boxed frame. Leave a few inches at the end of the string for future adjustments.

Sash Cords

In the majority of double-hung windows, a cord or chain is attached to the weights. This keeps the sashes within the jamb level. 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 ensure it stays in place when opened.

To replace sash cords the first step is to remove the access panels from the jambs. These are usually fixed or screwed in and must be removed or moved. You may be able to use a hammer and chisel to prise them off, but it's always better to lay down dust sheets prior to beginning any work.

Once the access panel is removed, you can begin working on the sash. Utilize a flat bar or chisel to pry the small partsing beads out of their grooves. It's important to be patient as they're often placed in a wedge or nail. If the sash is in place, break the mortise and tenon joints with the help of a hammer and pin or screwdriver, then remove the wood pegs attached to each component. You should be able to move the sash back and forth freely, although it may require lubrication if it feels stiff.

With the sash in an open position With the sash in an open position, measure the sash chain or cord to extend from the pulley at the top of the jamb to the sash slot in the bottom. Cut the chain or cord and secure it as in the previous step. You can either employ a hammer and nail or screws, but nails are less likely to cause damage.

It is recommended to keep the original weights in place unless you've purchased a kit that will replace the counterbalance that was previously installed. They are not expensive and simple to install if you purchase them from salvage shops for architectural use. Depending on the size of your window repair (Additional Info), one or two sash weights may be needed to keep the sash in an open position.
