Wooden window sashes can add an elegant appearance to your home. They are also sturdy and can last many years if they are properly maintained. However, they can become damaged or degraded with time due to exposure or normal wear and tear.

The first step in repair sash window damage is to fix weather stripping, which can be found on both the sash and frame. If it's loose or worn out, it could cause drafts, as well as other issues. To fix it, start 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). Then, remove the sash and mark its width and height so that you can locate replacement weather stripping to match.
Then, remove Hackney window repairs and set it on a surface to allow access to all four sides. If your sash is double-hung, you'll need to remove the weights and their accompanying ropes which should have slipped into the pocket of the jamb liner. After removing the sash with the utility knife, remove the weather stripping from the old sash by hand or using a putty blade.
After the sash has been cleared, you can replace parting stops. These are long pieces that separate the sashes. Pam likes to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you can also replace them with a piece of scrap wood.
After removing the stopper and cutting it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using a putty tool, and let it dry at least a day. Once the putty has fully cure and dried, you can apply an acrylic latex topcoat. This coating will protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that supports window sashes can wear out over time and with use. This could result in a door or a window that is difficult to open or close. It's a good idea to know that replacing and fixing this hardware is usually simple and inexpensive. If a sash is difficult to operate try spraying grease into the jamb channel, and then open it to see if it fixes the problem. If the issue continues it's likely that the sash balance is off. You will need remove the window sash to access the hardware.
The ideal situation is for window sashes to swing open and closed without effort, however, this can be a difficult task when the weights wear out or if the sash meeting rail isn't properly coated. This issue could be caused by a variety of things, such as the lack of maintenance or the wrong weight rating for a particular sash.
If the hinge arms on the window begin to move, this can cause the sash drag and then hit the frame in the opposite corner (Photo 1). To fix the problem make sure the sash is aligned in the frame opening, and then remove it. If the sash has been screwed to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).
Due to hinges that are sagging, and a general lack in energy efficiency, older windows particularly those in older homes, may be difficult to open and close. In many cases just a few easy fixes can help these windows function smoothly and save homeowners money on energy bills.
It is crucial to have the tools you require before you begin. Mark the hinge channel location on the frame (Photo 1) with pencil. This will help you to place the channel in the proper position after you've finished. Then, remove the sash and take off the hardware including the beads that separate (Photo 2) and the chains or cords that secure it. A hot gun with nozzle shield and a medium setting will soften any putty that has been hardened. Remove the old sash and put it in a bag with a label.
Sash Weights
Sash weights are able to be replaced to enhance the efficiency of your window sash, and also reduce energy costs. Sash weights are heavy lead or iron cylinders that are enclosed in a concealed cavity and attached to the movable window sash using a rope. These weights act as counterbalances, allowing you to open and shut the window without requiring mechanical or electrical devices. If they fail, sashweights are often left unnoticed or disabled by homeowners.

It is difficult to recover an sash-weight which has fallen from the cavity, so you'll need to find one that fits correctly. You will also require a new piece string, a length 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. The wood pegs holding the parts together can be removed using a pin punch and hammer. The majority of these pegs are large on one side, and smaller on the other. It is essential to remove first the smaller diameter sides. Sashes that were made later in the century used glue instead of pegs and can be separated by cutting the glue line with the help of a knife, and then tapping the mortised section loose with mallets.
Once the sash has been released, you can remove the stops on the sash and get access to the pockets for weights. Usually, this is done through an opening at the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the inner workings.
Once the sash is stopped and the access panel has been removed, you can remove the old weight and replace it. Make sure you weigh the sash prior to you do this, as the old weights could be a different size than the one you need. After the new weight is installed you can tie a string around it and then thread it through the pulley of the sash. Then, nail the string to your boxed frame. Leave a few inches protruding at the head of the string for future adjustments.
Sash Cords
Most double-hung windows of the past include a chain or cord attached to the weights which helps keep the sashes balanced in the jamb. As time passes, these cords may become damaged and render it impossible to raise windows. 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. They are typically screwed or nailed in and require removal. You could employ a hammer and chisel to remove them but it's best to lay down dust sheets prior to beginning any work.
After removing the access panel, you are able to begin to work on the sash. Utilize a flat bar or chisel, to pry the narrow parting beads out of their grooves. It's important to take your time because they are usually stuck or nailed to the floor. If the sash remains in place, break the mortise-and tenon joints with a screwdriver or hammer, then remove each wood peg. You should be able to move the sash around without difficulty, though it may require lubrication if it feels stiff.
With the sash open, measure enough sash cord/chain to reach from the pulley on the top of the jamb to the sash slot at the bottom. Cut the cord/chain and then secure it in the step 6 above. You can do this with nail, hammer or screws. However, nails are less likely than screws to cause damage.
If you haven't purchased an item that replaces the old counterbalance system, it's recommended to keep the original weights for balancing in place. It's not too expensive to purchase them from a salvage store and they will be easy to install once you have the sash unlocked. Depending on the size of your window two or three sash weights may be needed to keep it in an open position.
