Window Sash Repairs

Sashes for windows must be checked regularly for mold, mildew, and damage. If you catch these issues early you can save money on repairs in the future.

The sash is an interior frame that can move up and down vertically in windows that are open. This article will teach you how to do a variety of simple repairs to sash.

Weather Stripping

Wood window sashes provide the classic look to your home. When properly maintained, they can last for years. However, they can get damaged or deteriorated over time, due to exposure and normal wear and tear. However, sash repair experts can restore your windows to their original condition and keep them looking great for much longer than newer replacement windows.

The first step in sash window repairs is addressing weather stripping. It's found on both the sash as well as the frame. It can cause drafts if it's worn or loose. To fix it, start by determining the brand of your window and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its height and width so that you can locate the appropriate weather stripping replacement to match.

Then, take the sash from its holder, and place it on a flat surface to allow you to reach all four sides. If the sash is double glazed window repairs-hung, you'll need to remove the weights and their accompanying ropes, which should have fallen into the pocket of the jamb liner. Once you've removed the sash and the weights, use a utility knife to remove the weather stripping that was formerly in place at the corners, and then remove it by hand or using a putty knife.

After the sash is cleared, you can install parting stops. These are long pieces that divide the sashes. Pam prefers to use standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you can 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 over the bottom of the sash. Smooth the compound using your putty tool, and let it dry at least a day. When the putty is fully cured and dried, you can apply a topcoat of acrylic. This coating will protect the putty and give your sash a new look.

Sash Hardware

The hardware that supports window sashes prone to wearing out from time and usage, and the result can be a door or window that isn't able to open or close easily. The good news is that fixing and replacing this hardware is typically quite simple and inexpensive. If a sash is difficult to operate try spraying grease into the jamb channel and then open it to see if that solves the issue. If not, the issue is likely to be with the balance of the sash and you'll need to take out the sash to gain access to this hardware.

Ideally, window sashes must be able to open and close with very little effort, however, this can be a difficult task when the weights are worn or if the sash that joins rail isn't properly double glazed window repairs near me. This can be due to a variety of factors, including a lack of maintenance and a mismatched weight rating.

If the hinge arms on a window begin to sag this could cause the sash to drag and then hit the frame in the opposite corner (Photo 1). To fix this problem, first ensure that the sash is squarely inserted into the frame's opening and then remove it from the window. If the sash was fixed to the hinge arm, remove the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).

Due to sagging hinges, and a general lack of energy efficiency, old windows particularly those in older homes, can be difficult to open and close. In many instances, a few minor repairs can transform these windows into smooth operators for the first time and save the homeowner money on energy costs.

It is important to have the tools needed before you begin. Mark the location of the hinge channel on the frame (Photo 1) using pencil. This will help you get the channel back on the correct position after you've finished. Remove the sash and then remove all hardware, including the parting beads, cords, and chains that help to hold the sash. Soften any putty that has been hardened with an electric heat gun set to medium and equipped with an shield for the nozzle. Remove the old sash and put it in a labelled bag.

Sash Weights

Whether your window sash repairs are to replace a damaged cord or to ensure that the windows are functional, replacing worn out weights on sash can improve sash operation and reduce energy consumption. Sash weights are heavy lead or iron cylinders enclosed inside a hidden compartment and linked to the moveable sash by rope. They are counterbalancers which allows the window to be shut and opened without the use of electrical or mechanical devices. When they fail, sashweights tend to be left unnoticed or disabled by homeowners.

It is difficult to recover a sash-weight that has fallen from the cavity, so you'll need to find one that fits properly. You will also require a fresh piece of string, a length of sashcord and a few sashpulleys to secure the weights you are replacing to the cord.

Mortise and Tenon joints are used to join older wood windows. The wood pegs that hold the parts together can be removed using pin punches and hammers. The majority of these pegs have large diameters on one side and a smaller one on the other side, so it is crucial to take out the smaller-diameter ones first. Later sashes utilized glue instead of pins. They can be cut with a knife and mallets.

Once the sash has been released, you can remove the sash stops and gain access to the weight pockets. Usually this is accomplished by drilling a hole near the bottom of each jamb. The hole is then covered with a wooden access panel that can be ripped off to allow you to view the inside of the frame.

After you have the sash stopped and the access panel removed, you will be able to remove the weight from the sash and replace it with new. Weigh the sash first, as the weights you've got may not be of the right size. After the new weight has been installed, run the string through the sash pulling mechanism. Then, nail the string to your boxed frame. Leave a few inches at the end of the string to allow future adjustments.

Sash Cords

In the majority of double glazed window repairs-hung windows, a cord or chain is connected to the weights. This supports and keeps the sashes within the jamb level. Over time, these chains may become damaged and render it impossible to raise windows. A new sash cable will give you the ability to move and lower the sash and keep it in place when opened.

To replace sash cords the first step is to remove the access panels from the jambs. They are typically screwed or nailed in and require removal. It is possible to remove them with a hammer or chisel, however, it is best to lay out dust sheets before starting any work.

After the access panel has been removed, you can start working on the sash. Take the narrow beads (also known as "tie rails") out of their grooves using the chisel or flat bar. These are often wedged in or nailed in, but they can be prised free which is why it's worth your time here. If the sash remains in place, pry the mortise-and tenon joints with a screwdriver or hammer and then take out each wood peg. The sash should move around freely now, however it might require some lubrication to make it feel less stiff.

With the sash in an open position, measure enough sash cord/chain to extend from the pulley at the top of the jamb to the sash slot on the bottom. Cut the cord/chain and then secure it as in Step 6 above. You can use a hammer, nails, or screws. However nails are less likely than screws to cause damage.

It is best to keep the original weights if you've purchased a kit that will replace the counterbalance. It's not too expensive to purchase them from architectural salvage stores and they will be easy to install once you have the sash opened. Depending on the size of your window repairs, one or two sashweights could be needed to keep it in an open position.
