Window Sash Repairs

Check the windows sashes regularly for damage, mildew, and mold. You can reduce 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 upwards and downwards in windows that are open. This article will teach you how to perform simple sash repairs.

Weather Stripping

Wood window sashes provide an elegant look to your home. If properly maintained, they can last for a long time. However, they may become damaged or degrade over time because of exposure to the elements and normal wear and tear. Sash repair experts can restore windows back to their original condition and maintain their beauty much longer than replacement windows.

The first step for repair sash windows is to address weather stripping, which can be found on both the sash as well as the frame. It can cause drafts if worn out or loose. Begin by identifying the brand of window and the manufacturer's date (etched on the glass's corner or the aluminum spacers between panes). Then, remove the sash and mark its width and height to find new weather stripping that matches.

Then, you can remove the sash from the holder and place it on an even surface that allows you to see all four sides. If your sash is double-hung, you'll have to remove the weights and the ropes that go with them, which should have fallen into the intended pocket in the jamb liner. After you've removed the sash, use a utility knife to cut off the old weather stripping at the corners, and then take it off by hand or using a putty knife.

Once the sash is clear it is time to replace the parting stops. They are long pieces of wood that separate the two sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. However, you can substitute with a scrap piece of wood.

After removing the stopper for the parting and trimming it to length, apply a thin coat of glazing compound over the bottom of the sash. Smooth it out using your putty knife, then let it dry for a minimum of a day. After the putty has completely cure and dried, you can apply a topcoat of acrylic latex. This will help protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that supports window sashes prone to wearing out from the wear and tear of use, and the result can be a window or door that can't be opened or closed easily. The good news is that repairing and replacing this hardware is generally quite simple and inexpensive. If a sash becomes difficult to operate try spraying oil into the jamb channel, and then open it to see if it resolves the issue. If the issue persists it's likely to be due to the sash's balance. You'll need to remove the window sash to get access to this part of the hardware.

Ideally, window sashes must move open and shut with very little effort, but this is a difficult task when the weights wear out or if the sash that joins rail isn't properly coated. This could be caused by many factors, including the lack of maintenance or a mismatched weight rating.

If the hinges on the window begin to move, this could cause the sash to drag, and then eventually to hit the frame in the opposite corner (Photo 1). To fix this issue, first make sure the sash is squarely inserted into the frame's opening and then take it out of the window. If the sash was screwed onto the hinge arm, remove the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).

Old windows, especially those in older houses, can be difficult to close and open due to hinges that are sagging and an overall inefficiency. In many cases it is a matter of making a few minor adjustments that can help these windows function smoothly once more and help homeowners save money on energy bills.

It is important to have the tools you need before you begin. Start by marking the location of the hinge channel on the frame with pencil (Photo 1). This will allow you to get the channel back on position correctly after you've completed. Take the sash off and then remove all hardware, including the beads for parting cords, chains, and cords that help to hold the sash. Heat gun with nozzle shield and medium setting will soften any hardened putty. Remove the old sash, and store it in an labelled bag.

Sash Weights


If your window sash repairs are to replace a broken cord or just to ensure that the windows are functional by replacing worn out sash weights will improve sash operation and help reduce energy consumption. Sash weights are made of heavy iron or lead cylinders that are enclosed in a hidden cavity and attached by ropes to the moveable window sash. These weights act as counterbalances, allowing you to open and close the window without requiring mechanical or electrical devices. If they fail, sashweights are usually left unnoticed or disabled by homeowners.

It is difficult to recover the sash-weight that fell from the cavity, so you'll need to find one that fits correctly. You will also require a new piece string, a length of sashcord and a few sashpulleys to secure the weights you are replacing to the cord.

Older windows made of wood are joined by mortise and tenon joints. Hammers and pins can be used to take out the wood pegs that hold the parts together. The majority of these pegs 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 made use of glue instead of pegs and can be separated by cutting through the glue line using the help of a knife, and then tapping the mortised section loose with a mallet.

After the sash is removed then you can take out the stopper on the sash and get access to the weight pocket. Usually it is done by drilling a hole near the bottom of each jamb. The hole is then covered with a wooden access panel that can be cut off to let you observe the inner workings of the frame.

After the sash has been stopped and the access panel removed, you'll be able to remove the weight from the sash and replace it with the new. 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, thread a string through the sash pulling mechanism. Then, attach the string to the boxed frame. Leave a few inches of space at the head of the string to allow future adjustments.

Sash Cords

Most old double-hung windows include a chain or cord attached to the weights which helps keep the sashes balanced in the jamb. As time passes, these cords may break, making it impossible to raise the window. A new sash cord can restore the ability to move the sash up and down and keep it 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 will need to be removed or relocated. You may be able to use a hammer or chisel to remove them, but it's always better to lay down dust sheets prior to starting 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 flat bar or chisel. These are often wedged in or nailed but can be prised free which is why it's worth your time. If the sash is in place, break the mortise and the tenon joints by using a hammer and pin punch or screwdriver, then unhook the wood pegs attached to each piece. It should now be possible to move the sash around without difficulty, though it may require oil if it feels stiff.

Measure the length of sash chain/sash cord required to reach the sash slot at the bottom from the pulley located at the top of the jamb. Cut the chain or cord, and then fix it using the step 6 above. look at this web-site can use either a hammer, nails or screws. However nails are less likely to cause damage.

Unless you've bought a kit that replaces the old counterbalance system, it's recommended to keep the original balancing weights in place. They're not costly and easy to install if you buy them from architectural salvage stores. Based on the size and shape of your window you may require one or two sashweights in order to keep the sash open.
