Window Sash Repairs

Window sashes must be inspected regularly for signs of mold, mildew, and damage. By catching these problems early you can save money on repairs in the future.

The sash is an interior frame that moves up and down vertically in windows that open. This article will demonstrate how to perform several simple sash repair.

Weather Stripping

Wooden window sashes can give an elegant appearance to your home. They are also durable and will last for many years if they are properly maintained. However, they can become damaged or deteriorate as time passes due to exposure to the elements and wear and tear. Thankfully, sash repair experts can restore your windows back to their original condition and maintain their appearance for much longer than newer replacement windows.

The first step to sash window repairs is addressing weather stripping, which can be found on both the sash and frame. If it's loose or worn out, it can cause drafts, as well as other issues. To fix it, begin by determining the brand of your Window repair and glass manufacturer date (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 purchase replacement weather stripping that matches.

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

Once the sash is clear and clean, you can put in the parting stops. These are long pieces that split the sashes. Pam prefers to use the standard 1/2-inch by 3/4 inch window trimming from the lumberyard. But, you can substitute a scrap piece of wood.

After removing the stopper for the parting and trimming it to length after which, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound using a putty tool, and let it dry at least a day. When the putty is fully cure it is possible to apply an acrylic latex topcoat. This will help protect the putty, and give your sash an updated appearance.

Sash Hardware

The hardware that supports window sashes can wear out over time and use. This could lead to windows or doors that is difficult to open or close. It's a good idea to know that replacing or fixing this hardware is usually easy and affordable. If a sash becomes difficult to operate you can try spraying some grease into the jamb channel, and then slide it open to see if this fixes the problem. If the issue continues, it is most likely the sash balance. It is necessary to remove the window sash to access the hardware.

Window sashes should open and close without much effort. However, this may be difficult if weights are worn out or the sash-to-rail connecting rail isn't covered with. This can be due to a variety of factors such as a lack of maintenance and a mismatched weight rating.

If the hinges on a window begin to sag 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 centered in the frame opening and then remove it. If the sash has been screwed to the hinge arm, you'll have to remove the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).

Due to hinges that are sagging, and a general deficiency in energy efficiency, older windows particularly those in older homes, can be difficult to open or close. Many times, a few simple fixes can help these windows function smoothly again and help homeowners save money on energy costs.

It is essential to have the tools you require before you begin. Mark the hinge channel's location on the frame (Photo 1) with a pencil. This will help you to position the channel in the proper location after you've completed. Then, remove the sash, and then remove the hardware, including the parting beads (Photo 2) and the cords or chains which hold it in place. Soften any putty that has been hardened with an electric heat gun set to medium and fitted with an nozzle shield. Remove the old sash, and keep it in a bag with a label.

Sash Weights

If your window sash repairs are to replace a broken cord or to keep the windows functional by replacing worn out sash weights will improve sash operation and reduce energy costs. Sash weights consist of iron or lead cylinders that are enclosed in a concealed cavity and connected by a rope to the movable window sash. These weights provide counterbalance which allows the window to be opened and closed without the use of electrical or mechanical devices. The sash weights are often ignored or discarded by homeowners, and are turned into scrap when they break; therefore you may have to locate replacements.

It's difficult to retrieve a sash-weight that has fallen from the cavity, so you'll want to find one that fits properly. You will also require a new piece of 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 using mortise and tenon joints. The wood pegs that hold the components together can be removed using pin punches and hammers. The majority of these pegs have an enormous diameter on one side and a smaller size on the other, so it is crucial to take out the smaller-diameter ones first. Later sashes made use of glue instead of pins. They can be separated with a knife and mallets.

Once the sash has been removed, you can take off the sash stops and access the pockets for weights. Usually it is done by drilling an opening at the bottom of each jamb. This hole is then covered by an access panel of wood which can be removed to allow you to observe the inner workings of the frame.

Once the sash is stopped and the access panel has been removed, you can take off the weight you used and replace it. Make sure you weigh the sash before you do this, as the old weights may be different sizes than the one you need. Once the new weight has been installed, thread the string through the sash pulling mechanism. Then nail the string to the boxed frame, leaving a few inches of string sticking out from the head to allow for future adjustments.

Sash Cords

In the majority of double glazed window repairs-hung windows, a chain or cord is attached to the weights. This helps keep the sashes of the jamb balanced. Over time, these cords can become damaged and render it impossible to raise the windows. A new sash cable can restore the ability to move and lower the sash, and ensure it stays in place when it is opened.

To replace sash cords, the first step is to remove the access panels from the jambs. These are usually installed by screws or nails and must be removed or repositioned. It is possible to take them out using the hammer or chisel but it is always better to lay out dust sheets before starting any work.

After removing the access panel, you can begin to work on the sash. Use a flat bar or chisel to pull the small parting beads from their grooves. These are often wedged in or nailed but can be prised free, so it's worth taking your time. If the sash remains in place, break the mortise-and tenon joints with a screwdriver or hammer and then remove each wood peg. You should be able to move the sash around freely, though it might require lubrication if it feels stiff.

Take a measurement of the length of sash chain/sash cord required to reach the sash slot on the bottom from the pulley on the top of the jamb. Cut the cord/chain and then attach it in the previous step. You can employ a hammer, nail or screws, but nails are less likely to cause damage.

It's best to leave the original weights in place unless you've purchased a kit to replace the counterbalance. They're not costly and are easy to install if you buy them from salvage shops for architectural use. Based on the size of your window, one or two sashweights may be needed to keep the sash in an open position.
