Window Sash Repairs

Make sure to check the sashes of your windows regularly for any damage, mildew and mold. If you catch these issues early you will save money on future upvc repairs.

The sash is an inside frame that is able to move up and down vertically in windows that are open. This article will show you how to do easy repairs to your sash.

Weather Stripping

Wooden window sashes can add a classic look to your home. They are also durable and will last for many years when they are maintained properly. However, they can become damaged or degraded with time, due to exposure and normal wear and tear. Sash repair experts can restore windows to their original state and maintain their appearance much longer than replacement windows.

The first step for sash window repairs is addressing weather stripping, which can be found on both the sash as well as the frame. It can cause drafts if it's worn or loose. Begin by identifying the brand of window and the manufacturer's date (etched on the corner of the glass, or the aluminum spacers between panes). Remove the sash, and mark its size and width so that you can get new weather stripping that is compatible with the original.

Next, remove the sash and set it on a work surface so that you can reach all four sides. If the sash is double-hung, you must remove the weights using their ropes that should have fallen into the pocket in the jamb lining. After you've removed the sash using a utility knife, you can use it to cut away the weather stripping from the corners, then remove it manually or using a putty blade.

Once the sash is clear and clean, you can put in the parting stops. These are long pieces that separate the sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. However, you could also substitute with a scrap piece of wood.

After removing the parting stops and trimming them to your desired length and thickness, apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound with your putty tool and let it dry for at least a day. After it has fully dried and dried, apply a second coat of acrylic latex paint. This will protect the putty and give your sash an updated look.

Sash window Repair Hardware

The hardware that supports window sashes is susceptible to wear and tear due to age and use, and the result can be a door or window that isn't able to open or close easily. It's good to know that replacing and fixing this hardware is usually easy and affordable. If you're having trouble opening a sash, spray some oil into the jamb channel. Then, you can slide the sash open to see if this resolves the problem. If not, the problem is likely with the sash balance and you'll need to remove the sash in order to access this hardware.

Window sashes need to be able to open and close with minimal effort. However, this could be difficult if the weights are worn out or the sash-to-rail meeting rail is not properly glazed. This issue can be caused by a variety of things, such as lack of maintenance or by a mismatched weight rating for the particular sash.

If the hinge arms of a window are beginning to slide, this could cause the sash's to drag and eventually strike the frame in the corner that's opposite the hinge arm (Photo 1). To fix the problem, make sure that the sash is in the proper position within the frame opening and then take it off. If the sash is screwed onto the hinge arm, remove the hinge and replace it. (Photo 2). Then, put in the new sash (Photo 3).

Old windows, especially those in older homes, can be difficult to open and close, because of sagging hinges and a general inefficiency. In most instances, a few easy repairs can transform these windows into smooth operation for the first time and save the homeowner money on energy bills.

To make these repairs to the sash it is important to have all of the necessary tools lined up before you begin. Begin by marking the position of the hinge channel on the frame with pencil (Photo 1). This will assist you in getting the channel back on the correct position after you've finished. Then, remove the sash, and then remove the hardware including the parting beads (Photo 2) and the cords or chains that secure it. A hot gun with nozzle shield and a medium setting can soften any hardened glue. Remove the old sash and place it in a bag with a label.

Sash Weights

No matter if your window sash repair needs are to replace a broken cord or simply to keep the windows functional, replacing worn out weights for sash will improve its operation and cut down on the energy cost. Sash weights are heavy, lead or iron cylinders that are enclosed in a hidden cavity and linked to the moveable the sash with rope. These weights provide counterbalance which allows the window to be closed and opened without the need for mechanical or electrical devices. The sash weights are usually ignored or discarded by homeowners and then turned into scrap when they fail. Consequently you might need to locate replacements.

A weight in a sash that has fallen out of the cavity is difficult to recover It is therefore important to locate a new one that fits correctly. You will also need an additional piece of string, a length of sash cord, and a few sash pulleys that will tie the new sash weights the sash cord.

Mortise and Tenon joints are used to join older wood windows. The wood pegs holding the parts together can be removed with a pin punch and hammer. The majority of these pegs have a large diameter on one side and a smaller size on the other, which is why it is important to remove the smaller-diameter ones first. Sashes that were made later in the century utilized glue instead of pegs and can be separated by cutting through the glue line using an instrument, and then tapping the mortised section loose using mallets.

Once the sash is freed and removed, you can take off the sash stop and gain access to the weight pocket. Usually this is accomplished by drilling an opening in the bottom of each jamb. This hole is covered by a wooden access panel that can be cut off to let you observe the inner workings of the frame.

After the sash has been stopped and the access panel is removed, you can remove the weight that was previously installed and replace it. Make sure you weigh the sash prior to you begin, as the weights that were previously used may be different sizes than what you require. Once the new weight is installed then tie a string to it and thread it through the pulley for the sash. Then nail the string to the boxed frame, but leave a few inches of string hanging from the head to allow for future adjustments.

Sash Cords

In the majority of double-hung windows, a cord or chain is attached to the weights. This keeps the sashes of the jamb balanced. Over time these cords can break, making it difficult to raise the window. A new sash cord can restore the ability to move the sash upwards and downwards and will keep it in its place when opened.

The first step in replacing sash cords is to locate and remove the access panels within the jambs. They are usually screwed or nailed into and need to be removed. It is possible to take them out using an axe or hammer, but it is always better to lay out dust sheets before starting any work.

Once the access panel is removed, you can start working on the sash. Make the small parting beads (also called "tie rails") out of their grooves with flat bar or chisel. These are often wedged in or nailed in, but they can be snipped out and it's worth your time here. If the sash remains in place, pry the mortise and tenon joints free using a hammer or screwdriver and then remove each wood peg. It should now be possible to move the sash back and forth without difficulty, though it may require lubrication if it feels stiff.

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

It is recommended to keep the original weights in place unless you have purchased a kit to replace the counterbalance that was previously installed. They're not costly and simple to install if you purchase them from architectural salvage stores. Depending on the size and shape of your window, you may need to use one or two sashweights to keep the sash open.
