Window Sash Repairs

Sashes for windows must be checked regularly for mold, mildew and other damage. You can save the cost of repairs in the future by catching problems in the early stages, before they become out of control.

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

Weather Stripping

Wooden window sashes are a great way to add an elegant appearance to your home. They are also durable and last for a long time provided they are properly maintained. However, they can become damaged or degraded with time due to exposure or normal wear. Sash repair experts can restore windows to their original state and maintain their appearance longer than replacement windows.

The first step in sash window repairs is addressing weather stripping, which is found on both the sash and frame. If it's loose or worn out, it can lead to drafts and other issues. Start by identifying the brand of window repair near me and the manufacturer's date (etched on the glass's corner, or the aluminum spacers between panes). Then, remove the sash and mark its height and width to find the appropriate weather stripping replacement to match.

Next, remove the sash and set it on a surface to allow access to all four sides. If your sash has a double-hung, you'll also need to remove the weights and their accompanying ropes, which should have fallen into the pocket of the jamb liner. After you've removed the sash using a utility knife, you can use it to cut away the old weather stripping at the corners. Then, remove it manually or with a putty knife.

After the sash has been cleared, you can replace parting stops. These are long pieces that separate the sashes. Pam prefers standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. However, you could also substitute for a scrap piece of lumber.

After removing the stopper and cutting it to length, apply a thin coat of glazing compound to the bottom of the sash. Smooth out the compound using your putty knife and let it dry for a minimum of a day. Once it's fully cured then apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a fresh appearance.

Sash Hardware

The hardware that supports the windows sashes can become worn out over time and use. This could result in the window or door repair that is difficult to open or close. The good thing is that fixing and replacing this hardware is generally quite simple and inexpensive. If you are having trouble opening the sash, spray some lubricant into the jamb channel. Then, you can slide the sash open to see if it resolves the problem. If the issue persists it's most likely that the sash balance is off. It is necessary to remove the window sash in order to access the hardware.

Window sashes should 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 connecting rail isn't properly covered with. This problem could be caused by many factors such as an absence of maintenance or an unmatched weight rating.

If the hinge arms of a window begin to slide, this could cause the sash to drag and eventually land on the frame in the corner directly opposite the hinge arm (Photo 1). To remedy the issue ensure that the sash is in the proper position within the frame opening, and then remove it. If the sash is screwed to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Next, install the new sash (Photo 3).

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

To complete these repairs to the sash it is important to have all of the necessary tools lined up before you begin. Mark the location of the hinge channel on the frame (Photo 1) using a pencil. This will allow you to get the channel back into the correct position after you've finished. Then, remove the sash and take off the hardware, including the parting beads (Photo 2) and the chains or cords which hold it in place. The nozzle shield of the heat gun and a 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 changed to improve the operation of your window sash, and also reduce the cost of energy. Sash weights consist of heavy lead or iron cylinders that are encased in a concealed cavity and are connected via ropes to the movable window sash. They function as counterbalances, allowing you to open and close the window without the need for mechanical or electrical devices. If they fail, sashweights tend to be ignored or disabled by homeowners.

It's difficult to retrieve an sash-weight which has fallen from the cavity, so you'll want to find one that is suitable for the. You will also require a new piece of string, a length sashcord and some sashpulleys to tie the weights you are replacing to the 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 that hold the components together. The majority of them have an enormous diameter on one side and a smaller diameter on the other side, so it is crucial to take out the small-diameter sides first. Sashes that were made later in the century used glue instead of pegs and can be separated by cutting the glue line using an instrument, and then tapping the mortised part loose with a mallet.

Once the sash is freed then you can take out the stopper on the sash and get access to the weight pocket. Usually this is accomplished by drilling an opening in 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'll be able to remove the old sash weight and replace it with the new. Be sure to weigh the sash prior to you begin, as the old weights may be different in size from what you require. After the new weight has been installed, run a string through the sash pulling mechanism. Then, you can attach the string to your boxed frame. Leave a few inches protruding at the end of the string for future adjustments.

Sash Cords

In the majority of double-hung windows, a chain or cord is connected to the weights. This keeps the sashes of the jamb balanced. As time passes, these cords can get damaged and render it impossible to raise windows. A new sash cable will restore the ability to raise and lower the sash and keep it in place when it is opened.

The first step to replace sash cords is to locate and take out the access panels located in the jambs. These are usually attached by nails or screws and need to be removed. It is possible to remove them using the hammer or chisel however, it is best to lay out dust sheets prior to starting any work.

After you have removed the access panel, you are able to begin to work on the sash. Use a flat bar or chisel, to pry the narrow parting beads out of their grooves. It's important to take your time, as these are often placed in a wedge or nail. If the sash is in place, pry out the mortise and tenon joints with the help of a hammer and pin or screwdriver, then remove the wood pegs that are on the components. The sash should be able to move freely, however it may need some lubrication to feel less stiff.

Measure the length of sash cord/chain required to reach the sash slot at the bottom from the pulley on the top of the jamb. Cut the chain or cord and fix it as described in Step 6 above. You can do this with a hammer, nails, or screws. However nails are less likely to cause damage.

If you haven't purchased a kit that replaces the old counterbalance system it's best to keep the original balancing weights in place. It's not expensive to buy them from a salvage store and they will be easy to install once you have the sash opened. Based on the size of your window one or two sashweights may be needed to keep the sash in an open position.
