Window Sash Repairs

Check the windows sashes regularly for any damage, mildew and mold. You can avoid future repair costs by catching the issues early on before they become out of control.

The sash is the interior frame that is vertically moved up or down in windows that open. This article will show you how to do a variety of simple repairs to sash.

Weather Stripping

Wood window sashes give an elegant look to your home and, when properly maintained, can last for years. However, they may become damaged or degraded as time passes because of exposure to the elements and normal wear and wear and tear. However, sash repair experts can restore your windows back to their original condition and maintain their appearance for longer than 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 lead to drafts, as well as other issues. To fix it, begin by determining the brand of your window repairs 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 you can find replacement weather stripping to match.

Then, take it off and set it on a work surface to allow access to all four sides. If your sash is double glazing near me-hung, you'll need to take off the weights and the ropes that go with them, which should have fallen into the intended pocket in the jamb liner. Once you've removed the sash using a utility knife, you can use it to cut off the weather stripping that was formerly in place at the corners, then remove it manually or using a putty knife.

Once the sash has been cleared, you can install the stoppers that separate the two sashes. These are long pieces that separate the sashes. Pam prefers to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you can also use a piece of scrap wood.

After removing the parting stop and trimming it to length after which, apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound using a putty tool and allow it to dry for at least a day. Once it's fully cured, apply a top coat of acrylic latex paint. This will protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that supports the windows sashes can become worn out over time and with use. This could result in the window or door that is difficult to open or close. It's good to know that replacing and fixing this hardware is usually straightforward and cost-effective. If a sash isn't easy to operate, try spraying some lubrication into the jamb channel, and then open it to see if that solves the issue. If not, the issue is likely with the sash balance and you'll have to take off the sash to gain access to the hardware.

The ideal situation is for window sashes to move open and shut with very little effort, but this can be difficult when the weights wear out or if the sash's meeting rail isn't properly coated. This issue can be caused by a variety of factors, including the lack of maintenance or the wrong weight rating for the specific window sash.

If the hinges on a window begin to sag this can cause the sash drag and then hit the frame at the opposite corner (Photo 1). To fix this problem, first ensure that the sash is firmly seated in the frame's opening and then remove it from the window. If the sash has been fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Because of sagging hinges and a general deficiency in energy efficiency, older windows especially in older homes, can be difficult to open and close. In most cases, a few simple repairs can transform these windows into smooth operators for the first time and save the homeowner cash on energy costs.

It is important to have the tools you require before you start. Mark the hinge channel's location on the frame (Photo 1) with a pencil. This will make it easier to put the channel in the proper place when you are finished. Then, remove the sash and remove the hardware, including the parting beads (Photo 2) and the chains or cords that hold it in place. A hot gun with nozzle shield and medium setting will soften any hardened glue. Remove the old sash, and put it in a bag with a label.

Sash Weights

Sash weights can be replaced to improve the operation of your window sash and reduce energy costs. Sash weights are heavy, lead or iron cylinders that are enclosed in a hidden cavity and attached to the movable 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 typically ignored or discarded by homeowners and turned into scrap when they fail. Consequently, you may need to search for replacements.

It's difficult to retrieve the sash-weight that fell from the cavity, so you'll want to find one that fits correctly. You will also require a new piece of string, a length of sash cord and some sash pulleys to tie the new sash weights to the sash cord.

Older wood windows are joined using mortise and tenon joints. The wood pegs that hold the components together can be removed using a pin punch and hammer. The majority of them have a large diameter on one side and a smaller diameter on the other, which is why it is essential to remove the small-diameter sides first. Later sashes utilized glue instead of pins. They can be separated by using a knife or mallet.

After the sash is removed, you can remove the stopper on the sash and get access to the weight pocket. Usually, this is done through a hole near the bottom of each jamb. This hole is covered with a wooden panel that can be removed to reveal the inner workings.

After you have the sash stopped and the access panel removed, you will be able to take off the old sash weight and replace it with the new. Make sure you weigh the sash before you do this, since the old weights could be a different size than what is needed. After the new weight is installed, tie a string to it and thread it through the pulley for the sash. Then, nail the string to your boxed frame. Leave a few inches at the end of the string to allow for future adjustments.

Sash Cords

In the majority of double-hung windows the chain or cord is affixed to the weights. This helps keep the sashes in the jamb balanced. Over time, these cords could break, making it impossible to raise the window. A new sash cable will give you the ability to raise and lower the sash and keep it in position when it is opened.

The first step to replace cords for sash is to locate and remove the access panels in the jambs. These are usually screwed or nailed in and require removal. It is possible to remove them with a hammer or chisel, but it is always best to lay out dust sheets prior to starting any work.

After you have removed the access panel, you can begin to work on the sash. Take the narrow beads (also known as "tie rails") out of their grooves using flat bar or chisel. It is important to be patient, as these are often stuck or nailed to the floor. If the sash remains in place, remove the mortise and tenon joints using pin punch and hammer or screwdriver, then remove the wood pegs on the components. You should be able to move the sash around without difficulty, though it may require oiling if it seems 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 cord/chain and then secure it as in Step 6 above. You can do this with nail, hammer or screws. However, nails are less likely than screws to cause damage.

If you don't have an item that replaces the old counterbalance system, it's best to keep the original balancing weights in place. It's cheap to purchase them from architectural salvage stores and they'll be simple to install once you have the sash open. Depending on the size and shape of your window you might need to install one or two sashweights to keep it open.
