Weather Stripping

Wooden window sashes are a great way to add a classic look to your home. They are also sturdy and last for a long time provided they are properly maintained.

Sash repair specialists can restore windows to their original state and maintain their beauty much longer than replacement windows.

The first step for repair sash window damage is to fix weather stripping, which can be found on both the sash as well as the frame. It can cause drafts if worn or loose. To fix it, begin by finding your window brand and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Remove the sash, and mark its width and height so you can get replacement weather stripping that matches.

Next, remove the sash and place it on a surface to allow access to all four sides. If the sash is double-hung, you'll also need to take off the weights and their accompanying ropes that should have fallen into the pocket of the jamb liner. After you've removed the sash, use a utility knife to cut away the old weather stripping at the corners, then remove it manually or using a putty knife.

When the sash is clean, you can replace the parting stops. These are long pieces that split the 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 scrap wood.

After removing the parting stops and trimming them to the desired length and thickness, apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound using a putty knife, and let it dry for at least one day. After it has fully dried and dried, apply a second coat of acrylic latex paint. This will help protect the putty and give your sash a modern appearance.

Sash Hardware

The hardware that holds window sashes is susceptible to wear and tear due to time and usage, and the result can be a door or window that won't open or close easily. It's a good idea to know that replacing or repairing this hardware is often easy and affordable. If you're having difficulty opening a sash spray some oil into the jamb channel. Then slide the sash up and open to see if it resolves the problem. If the issue continues it's most likely to be due to the sash's balance. It is necessary remove the window sash in order to get access to this part of the hardware.


Sashes for windows should be able to open and close with little effort. However, this could be difficult if the weights are worn out or the sash-to-rail connecting rail isn't covered with. This issue can be caused by a number of things, such as the lack of maintenance or a mismatched weight rating for the particular sash.

If the hinge arms 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 remedy the issue make sure the sash is in the proper position within the frame's opening and remove it. If the sash was screwed onto 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 in energy efficiency, older windows particularly those in older houses, could be difficult to open and close. In many cases, a few simple repairs can turn these windows into smooth operators and save homeowners money on energy costs.

It is important to have the tools you need before you start. Mark the location of the hinge channel on the frame (Photo 1) using pencil. This will allow you to place the channel in the right location after you've completed. Remove the sash and take out all the hardware, including the beads for parting, cords, and chains that keep the sash in place. Soften any hardened putty with the help of a heat gun set at medium and fitted with a nozzle shield. 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 the windows functional and functional, replacing worn-out sash weights will improve sash operation and help reduce energy costs. Sash weights are heavy, lead or iron cylinders enclosed inside a hidden compartment and connected to the movable the sash with a rope. These weights act as counterbalances and allow you to open and close the window without requiring mechanical or electrical devices. When they fail, sashweights are often neglected or not used by homeowners.

It is difficult to recover a sash-weight that has fallen from the cavity, so you'll need to find one that fits correctly. 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 onto the sash cord.

Mortise and Tenon joints can be used to join windows made of older wood. Pin punch and hammer can be used to cut off the wood pegs holding the parts together. The majority of these pegs have a large diameter on one side and a smaller one on the other, which is why it is important to remove the smaller-diameter ones first. Later sashes used glue instead of pins. They can be cut by using a knife or a mallet.

After the sash is removed, you can take off the stops on the sash and get access to the weight pockets. Usually this is accomplished by drilling an opening at the bottom of each jamb. The hole is then covered with a wooden panel that 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 from the sash and replace it with the new. Be sure to weigh the sash first to ensure that the weights you have might not be the correct size. After the new weight is installed, run a string through the sash pulling mechanism. Then, attach the string to your boxed frame. Leave a few inches protruding at the end of the string for future adjustments.

Sash Cords

In most old double-hung window, a cord or chain is affixed to the weights. This supports and keeps the sashes in the jamb level. As time passes, these cords can become damaged and make it impossible to raise windows. A new sash cord will give you the ability to move the sash upwards and downwards and hold 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 fixed or screwed in and will require to be removed or moved. It is possible to take them out using a hammer or chisel, but it is always best to lay out dust sheets before starting any work.

After you have removed the access panel, you can begin to work on the sash. Utilize a flat bar, or chisel to pull the narrow parting beads from their grooves. It is important to take your time, as these are often stuck or nailed to the floor. If the sash remains in place, break the mortise and the tenon joints by using 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 without difficulty, though it might require oil if it feels stiff.

Measure the length of sash chain/sash cord required to reach the sash slot on the bottom from the pulley located at the top of the jamb. Cut the chain or cord and fix it as described in Step 6 above. You can do this with a hammer, nails, or screws. However nails are less likely than screws to cause damage.

If you don't have a kit that replaces the old counterbalance system, it's best to keep the original balancing weights in place. It's not too expensive to purchase these from salvage shops for architectural purposes and they'll be easy to install once you have the sash unlocked. Depending on the dimensions and shape of your window you may require one or two sashweights to keep the sash open.
