Regularly inspect the window sashes for signs of damage, mildew and mold. You can reduce future repair costs by catching these issues early before they become out of control.

The sash is the interior framing that moves vertically either up or down in windows that open. This article will show you how to perform several simple sash repair.

Weather Stripping

Wood window sashes provide an elegant look to your home and, when properly maintained, they can last for years. They may, however, become damaged or degraded with time due to exposure and normal wear. Sash repair experts can restore windows to their original state and maintain their beauty much longer than replacement windows.

The first step for sash Window repair repairs is addressing weather stripping, which is found on both the sash and frame. If it's worn or loose, out, it could cause drafts and other problems. To fix it, begin by finding your window brand and the date of manufacture for the glass (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 new weather stripping that matches.

Next, remove the sash and set it on a surface so that you can reach all four sides. If the sash is double-hung, remove the weights using their ropes that should have fallen into the pocket inside the jamb lining. After you have removed the sash using the utility knife, remove the old weather stripping by hand or using a putty knife.

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

After removing the parting stop and trimming it to length after which, apply a thin layer of glazing compound to the bottom of the sash. Smooth out the compound using your putty knife, and then let it dry for a minimum of a day. Once the putty has fully cured it is possible to apply a topcoat of acrylic latex. This coating will protect the putty and give your sash a new look.

Sash Hardware

The hardware that supports window sashes is prone to wearing out from time and usage, and the result can be a window or door that can't be opened or closed easily. It's good to know that replacing or fixing this hardware is usually straightforward and cost-effective. If a sash becomes difficult to operate you can try spraying some oil into the jamb channel and then open it to see if this fixes the problem. If not, the problem is likely with the sash balance and you'll have to take off the sash in order to access the hardware.

Ideally, window sashes should swing open and closed without effort, but this is a difficult task when the weights are worn or if the sash's meeting rail isn't properly coated. This issue could be caused by many factors such as a lack of maintenance and an unmatched weight rating.

If the hinge arms of a window begin to lose their elasticity, this could cause the sash to drag and eventually land on the frame in the corner in the opposite direction of the hinge arm (Photo 1). To address this problem, first ensure that the sash fits squarely in the frame's opening and then take it out of the window. If the sash has been attached to the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Windows that are old, especially in older homes, may be difficult to open and close, due to hinges that are sagging and a general inefficiency. In most instances, a few minor repairs can turn these windows into smooth operation again and save the homeowner cash on energy costs.

It is crucial to have the tools you require before you start. Begin by marking the position of the hinge channel on the frame with pencil (Photo 1). This will allow you to get the channel back on the correct position after you've finished. Take the sash off and take out all the hardware, including the parting beads, cords, and chains that help to hold the sash. Soften any hardened putty with an electric heat gun set to medium and fitted with a shield to block the nozzle. Remove the old sash and put it in a bag that is labeled.

Sash Weights

No matter if your window sash repair needs are to replace a broken cord or just to keep the windows functional and functional, replacing worn-out weights on sash can improve sash operation and reduce energy costs. Sash weights are made of heavy lead or iron cylinders that are encased inside a concealed cavity, and connected by ropes to the moveable window sash. These weights function as counterbalances, allowing you to open and close the window without the need for mechanical or electrical devices. If they fail, sashweights are often neglected or not used by homeowners.

A weight in a sash that has fallen out of the cavity is difficult to recover and you'll need to find a replacement that is suitable for the. You will also need a new piece of string, a length of the sash cord, as well as some sash pulleys to connect the new sash weights the sash cord.

Older windows made of wood are joined by mortise and tenon joints. Pin punch and hammer can be used to remove the wood pegs holding the components together. Most of these pegs have a large diameter on one side and a smaller size on the other, which is why it is crucial to take out the smaller-diameter sides first. Sashes made later in the century made use of glue instead of pegs and can be separated by cutting through the glue line using a knife, then tapping the mortised part loose using mallets.

Once the sash has been released, you can remove the sash stops and access the pockets for weights. Usually this is accomplished by drilling a hole near the bottom of each jamb. The hole is then covered with an unfinished wooden panel that can be removed to reveal the inner workings.

Once you have the sash stopped and the access panel removed, you will be able to take off the weight from the sash and replace it with the new. Weigh the sash first, as the weights you have may not be the right size. After the new weight is in place then tie a string to it and then thread it through the pulley of the sash. Then, attach the string to your boxed frame. Leave a few inches of space at the top of the string to allow for future adjustments.

Sash Cords

Most old double glazed window repairs-hung windows come with a chain or cord attached to the weights that keeps the sashes level within the jamb. Over time, these cords could break, making it impossible to raise the window repairs. A new sash cable can restore the ability to raise and lower the sash, and keep it in place when it is opened.

The first step in replacing sash cords is to locate and take out the access panels located in the jambs. These are usually screwed or nailed into and need to be removed. You could use a hammer and chisel to prise them off however, it is always best to lay down dust sheets before beginning any work.

Once the access panel is removed, you can start working on the sash. Use a flat bar or chisel to pry the tiny partsing beads out of their grooves. It's important to be patient, as these are often wedged or nailed in place. If the sash remains in place, break the mortise-and tenon joints with a screwdriver or hammer, then remove each wood peg. The sash should be able to move freely now, but it may need some lubrication to make it feel less stiff.

Measure the length of sash cord/chain required to reach the sash slot at the bottom, and the pulley at the top of the jamb. Cut the cord or chain and fix it as described in the previous step. You can either use a hammer and nail or screws, but nails are less likely to cause damage.

Unless you've bought an upgrade kit to replace the old counterbalance system, it is recommended to keep the original weights for balancing in place. They are not expensive and easy to install if you buy them from architectural salvage stores. Depending on the size and shape of your window, you may require one or two sashweights in order to keep the sash open.
