Window Sash Repairs

Window sashes must be inspected regularly for signs of mold, mildew and other damage. You can reduce future repair costs by catching these issues in the early stages, before they become too much.

The sash is the internal framing that can be moved vertically up or down in windows that open. This article will teach you how to perform simple sash repairs.

Weather Stripping

Wooden window sashes can give a classic look to your home. They are also durable and can last many years provided they are properly maintained. However, they can get damaged or deteriorated over time, due to exposure and normal wear. Thankfully, sash repair experts can bring your windows back to their original condition and maintain their appearance for much longer than newer replacement windows.

The first step for sash window repairs is addressing weather stripping, which can be found on both the sash and frame. If it's worn or loose, out, it can cause drafts and other issues. 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). Remove the sash and mark its width and height so you can get replacement weather stripping that matches.

Next, remove the sash and set it on a table so you can access all four sides. If your sash has a double glazed window repairs near me-hung, you'll also need to remove the weights as well as the ropes that go with them, which should have fallen into the pocket of the jamb liner. After removing the sash using the utility knife, remove the old weather stripping by hand or with a putty knife.

After the sash has been cleared it is time to replace the parting stops. These are long pieces that split the sashes. Pam prefers to use standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you could also substitute a scrap piece of wood.

After removing the stopper and cutting it to length after which, apply a thin layer of glazing compound over the bottom of the sash. Smooth out the compound using your putty knife, and then let it dry for at least a day. When it's completely dried and dried, apply a second coat of acrylic latex paint. This will protect the putty and give your sash an updated appearance.

Sash Hardware

The hardware that holds window sashes is susceptible to wear and tear due to age and use, and the result can be a window or door that can't be opened or closed easily. It's a good idea to know that replacing or repair of this hardware is typically easy and affordable. If you are having trouble opening the sash, spray some grease into the jamb channel. Then slide the sash open to see if this resolves the problem. If not, the issue is likely with the sash balance and you'll have to take off the sash in order to access this hardware.

Sashes for windows should be able to open and close without much effort. However, this can be difficult if the weights are worn out or the sash-to-rail meeting rail is not properly covered with. This problem can be caused by a variety of reasons, such as lack of maintenance or by the wrong weight rating for the specific window sash.

If the hinge arms of a window are starting to lose their elasticity, this could cause the sash to slide and eventually hit the frame in the corner opposite the hinge arm (Photo 1). To resolve this issue, first make sure the sash is firmly seated in the frame's opening and then remove it from the window. If the sash is screwed to the hinge arm, you'll need to remove the hinge arm and replace it (Photo 2). Then, you can install the new sash (Photo 3).

Due to hinges that are sagging, and a general deficiency in energy efficiency, windows that are old particularly those in older houses, could be difficult to open or close. In many cases just a few easy fixes can allow these windows to operate smoothly once more and save homeowners money on energy bills.

In order to make these repairs to the sash it is essential to have all the necessary tools in place before you begin. Begin by marking the position of the hinge channel on the frame using a pencil (Photo 1). This will assist you in getting the channel back on the correct position after you've finished. Take the sash off, and remove all the hardware including the parting beads, cords, and chains that keep the sash in place. A hot gun with nozzle shield and a medium setting will soften any hardened glue. Remove the old sash, and store it in an labelled bag.

Sash Weights

Sash weights are able to be replaced to improve the operation of your window sash and reduce the energy cost. Sash weights are heavy, lead or iron cylinders, which are enclosed in a concealed cavity and linked to the moveable sash by a rope. These weights provide counterbalance, allowing 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 break; therefore you might need to search for replacements.

It is difficult to recover a sash-weight that has fallen from the cavity, so you'll want to find one that fits correctly. You will also need an additional piece of string, a length of sash cord and some sash pulleys to tie the new sash weights the sash cord.

Mortise and Tenon joints can be used to join old wood windows. The wood pegs holding the components together can be removed by pin punches and hammers. The majority of them are large on one side and smaller on the other. It is important to first remove the smaller diameter sides. Later sashes made use of glue instead of pins. They can be separated by using a knife or mallet.

After the sash has been removed then you can take out the sash stop and gain access to the weight pocket. Usually, this is done through a hole near the bottom of each jamb. This hole is then covered by a wooden access panel that can be cut off so that you can view the inside of the frame.

When the sash has been shut off and the access panel is removed, you can remove the weight you used and replace it. Be sure to weigh the sash before you do this, as the old weights may be different in size from the one you need. After the new weight has been installed, thread a string through the sash pulling mechanism. Then, you can attach the string to the boxed frame. Leave a few inches protruding at the head of the string to allow future adjustments.

Sash Cords

In the majority of old double-hung windows, a chain or cord is connected to the weights. This keeps the sashes in the jamb level. Over time, these cords can become damaged and render it impossible to raise windows. A new sash cord will give you the ability to move the sash upwards and downwards and will keep it in its position when it is opened.

To replace sash cords the first step is to remove the access panels from the jambs. They are usually attached by nails or screws and require removal. You may be able to use a hammer and chisel to prise them off, but it's always better to lay down dust sheets prior to beginning any work.

After you have removed the access panel, you are able to begin working on the sash. Take the narrow beads (also known as "tie rails") out of their grooves with a chisel or flat bar. It is important to be patient because they are usually wedged or nailed in place. If the sash is still in place, break the mortise and tenon joints using the help of a hammer and pin or screwdriver, and then take out the wood pegs attached to each piece. The sash should move freely, however it may require some lubrication to feel less stiff.

With the sash open, measure enough sash cord/chain to reach from the pulley in the top of the jamb to the sash slot in the bottom. Cut the chain or cord and fix it as described in the previous step. You can use a hammer and screws or nails, however nails are less likely to cause damage.

It is best to keep the original weights in place unless you've purchased a kit to replace the counterbalance that was previously installed. It's not expensive to buy these from salvage shops for architectural purposes and they'll be simple to install once you have the sash open. Depending on the size and shape of your window you may require one or two sashweights in order to keep the sash open.
