Weather Stripping

Wood window sashes give the classic look to your home. When properly maintained, they will last for many years. However, they can be damaged or degrade as time passes due to exposure to elements and normal wear and tear. Sash repair experts can restore windows to their original state and keep them looking great much longer than replacement windows.

Weather stripping is the most important issue to take care of when fixing windows that have sash. It's on both the frame and sash. If it's worn or loose, out, it could cause drafts, as well as other issues. Begin by identifying the brand of window and the date of manufacture for the glass (etched on the glass's corners or on the aluminum spacers between panes). Take the sash off, and mark its size and width so that you can purchase new weather stripping that is compatible with the original.

Then, remove the sash and set it on a work surface so that you can reach all four sides. If your sash is double-hung, you'll need to remove the weights and their accompanying ropes that should have fallen into the intended pocket in the jamb liner. Once you've removed the sash and the weights, use a utility knife to cut off the weather stripping that was formerly in place at the corners, and then remove it manually or using a putty knife.

Once the sash has been cleaned, you can replace parting stops. These are long pieces 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. However, you could also use a piece of scrap wood.

After removing the stopper and trimming it to length, apply a thin coat of glazing compound to the bottom of the sash. Smooth the compound with your putty knife, and then let it dry for at least a day. After the putty has completely cure, you can apply a topcoat of acrylic. This will help protect the putty and give your sash a modern look.

Sash Hardware

The hardware that holds window sashes is prone to wearing out from 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 and replacing this hardware is typically quite simple and inexpensive. If a sash isn't easy to operate you can try spraying some lubrication into the jamb channel then slide it open to see if it solves the issue. If the issue persists, it is most likely the sash balance. You will need to take off the window sash to get access to this part of the hardware.

Window sashes need to be able to open and close with minimal effort. However, this can be difficult if weights are worn out or the sash-to-rail connecting rail isn't properly glazed. This problem can be caused by a variety of things, such as the lack of maintenance or an incorrect weight rating for the specific sash.

If the hinge arms on a window begin to sag this can cause the sash drag and then hit the frame at the opposite corner (Photo 1). To address this problem, first ensure that the sash is firmly seated in the frame's opening and then take it out of the window. If the sash has been screwed to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).

Due to sagging hinges, and a general lack in energy efficiency, older windows particularly those in older houses, could be difficult to open or close. Sometimes just a few easy fixes can help these windows function smoothly and save homeowners money on energy costs.

In order to make these repairs to the sash it is important to have all of the necessary tools in place before you begin. Mark the location of the hinge channel on the frame (Photo 1) using a pencil. This will allow you to get the channel back on place correctly when you're finished. Remove the sash and take off 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 an shield for the nozzle. Remove the old sash and put it in a bag that is labeled.

Sash Weights

If your window sash repairs are to replace a broken cord or just to keep your windows functioning and functional, replacing worn-out weights on sash can improve sash operation and cut down on energy costs. Sash weights consist of heavy iron or lead cylindricals that are contained inside a concealed cavity, and are connected via ropes to the movable window sash. These weights act as counterbalances and allow you to open and shut the window without having to use mechanical or electrical devices. If they fail, sashweights are often ignored or disabled by homeowners.

It's difficult to retrieve a sash-weight that has fallen from the cavity, so you'll want to find one that fits correctly. You will also require an additional piece of string, a length the sash cord, as well as some sash pulleys to tie the new sash weights onto the sash cord.

Older windows made of wood are joined using mortise and tenon joints. Pin punch and hammer can be used to take out the wood pegs holding the components together. The majority of these pegs have an enormous diameter on one side and a smaller one on the other side, so it is crucial to take out the smaller-diameter sides first. Later sashes made use of glue instead of pins. They can be cut by using a knife or a mallet.

After the sash is released, you can remove the stops on the sash and get access to the weight pockets. This is typically done by drilling an opening in the bottom of each jamb. The hole is then covered with a wooden access panel that can be ripped off to allow you to observe the inner workings of the frame.


When the sash has been shut off and the access panel has been removed, you can remove the weight that was previously installed and replace it. First, weigh the sash because the weights you have may not be of the right size. After the new weight is installed then tie a string to it and then thread it through the pulley for the sash. Then, nail the string to the boxed frame. Leave a few inches protruding at the top of the string to allow future adjustments.

Sash Cords

Most old double-hung windows come with a chain or cord connected to the weights that supports and keeps the sashes in balance in the jamb. Over time, these cords can get damaged and render it impossible to raise the windows. A new sash cord will restore the ability to move the sash up and down and hold it in position when it is opened.

The first step in replacing cords for sash is to locate and take out the access panels located in the jambs. These are usually installed by screws or nails and will require to be removed or moved. You may be able to employ a hammer and chisel to prise them off but it's best to lay down dust sheets before commencing any work.

Once the access panel is removed, you can start working on the sash. Use a flat bar or chisel, to pry the tiny parting beads from their grooves. It is important to be patient as they're often placed in a wedge or nail. If the sash remains in place, remove the mortise and tenon joints with the help of a hammer and pin or screwdriver, then remove the wood pegs attached to each piece. The sash should be able move around freely now, however it may require some lubrication to feel less stiff.

Determine the length of the sash chain or sash cord required to reach the sash slot on the bottom of the pulley on the top of the jamb. Cut window repairs or cord and then secure it in Step 6 above. You can either employ a hammer and screws or nails, however nails are less likely to cause damage.

If you haven't purchased an item that replaces the old counterbalance system, it's best to keep the original balancing weights in place. They're not expensive and are easy to install if you buy them from architectural salvage stores. Depending on the dimensions and shape of your window you might need to install one or two sashweights to keep it open.
