Weather stripping is the most important thing to address when repairing windows with sash. It is located on both the frame and sash. It could cause drafts if worn or loose. To fix it, begin by finding your window brand and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its width and height, so you can find replacement weather stripping to match.

Then, remove the sash from the holder and place it on flat surfaces to allow you to access all four sides. If your sash has a double-hung, you'll also need to remove the weights as well as their ropes that should have fallen into the intended pocket in the jamb liner. After you have removed the sash using the utility knife, take off the weather stripping from the old sash by hand or with a putty blade.

Once the sash has been cleared, 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, but you can also replace them with scrap wood.

After removing the stoppers for parting and trimming them to your desired length, apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound with your putty tool, and allow it to dry for at least a day. When it's completely dried, apply a top coat of acrylic latex paint. window repairs near me will protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that supports window sashes is susceptible to wear and tear due to the wear and tear of use, and the result can be a door or window that won't open or close easily. The good news is that fixing and replacing this hardware is generally very simple and cost-effective. If you're having trouble opening a sash spray some oil into the jamb channel. Then, you can slide the sash out to see if it resolves the problem. If the issue persists it's most likely that the sash balance is off. You'll need to remove the window sash in order to get access to this part of the hardware.

Ideally, window sashes should be able to open and close without effort, but this is a difficult task if the weights become worn or if the sash meeting rail isn't properly coated. This could be caused by a variety of factors, including the lack of maintenance or an unmatched weight rating.

If the hinge arms of a window are beginning to slide, this could cause the sash to drag and eventually land on the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To address this issue, first make sure the sash is firmly seated in the opening of the frame and then take it out of the window. If the sash is screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Old windows, particularly those in older homes, may be difficult to open and close because of sagging hinges and an overall lack of energy efficiency. In many instances, a few easy repairs can turn these windows into smooth operation again and save the homeowner money on energy costs.

It is essential to have the tools you need before you begin. Mark the location of the hinge channel on the frame (Photo 1) using pencil. This will help you to position the channel in the right location after you've completed. Then, remove the sash and remove the hardware, including the parting beads (Photo 2) and the chains or cords that hold it in place. The nozzle shield of the heat gun and medium setting will soften any hardened glue. Remove the old sash and store it in an bag with a label.

Sash Weights

Sash weights can be changed to improve the performance of your window sash and reduce the cost of energy. Sash weights are composed of heavy lead or iron cylindricals that are contained inside a concealed cavity, and are connected via ropes to the moveable window sash. They function as counterbalances and allow you to open and close the window without having to use mechanical or electrical devices. The sash-weights are typically disregarded or disabled by homeowners and then turned into scrap when they break; therefore, you may need to find replacements.

A sash weight that has fallen out of the cavity is difficult to get back, so you will want to locate a new one that fits properly. You will also require a new piece string, a length sashcord and some sashpulleys to tie the new weights to the cord.

Older windows made of wood are joined with mortise and tenon joints. Pin punch and hammer can be used to remove the wood pegs holding the parts together. Most of these pegs have a large diameter on one side and a smaller diameter on the other, so it is essential to remove the smaller-diameter sides first. Later sashes utilized glue instead of pins. They can be separated by using a knife and mallets.

After the sash is 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. This hole is covered with an unfinished wooden panel that can be removed to reveal the inner workings.

Once the sash is stopped and the access panel is removed, you can remove the weight you used and replace it. Be sure to weigh the sash prior to you do this, since the weights that were previously used may be different in size from what is needed. After the new weight has been installed, you can thread a string through the sash pulling mechanism. Then, nail the string to the boxed frame. Leave a few inches of space at the top of the string to allow for future adjustments.

Sash Cords

In the majority of old double-hung windows, a cord or chain is attached to the weights. This supports and keeps the sashes within the jamb in a balanced manner. Over time, these cords could break, making it difficult to raise the window. A new sash cord will give you 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 attached by nails or screws and must be removed. You could employ a hammer and chisel for removing them, but it's always better to lay down dust sheets before starting any work.

Once the access panel is removed, you can start working on the sash. Take the narrow beads (also known as "tie rails") out of their grooves using the chisel or flat bar. They are typically wedged into or nailed, but they can be snipped out, so it's worth taking your time here. If the sash is still in place, break the mortise and tenon joints with pin punch and hammer or screwdriver, and then take out the wood pegs attached to each piece. It should now be possible to move the sash around freely, although it might require oil if it feels stiff.

Measure the length of sash chain/sash cord needed to reach the sash slot at the bottom of the pulley on the top of the jamb. Cut the cord or chain and secure it in the step 6 above. You can either use a hammer and nail or screws, but nails are less likely to cause damage.

Unless you've bought an item that replaces the old counterbalance system, it is recommended to keep the original balancing weights in place. It's not too expensive to purchase them from architectural salvage stores and they'll be simple to install once you've got the sash opened. Depending on the size of your window one or two sash weights could be needed to keep it open.
