Window Sash Repairs
Check the windows sashes regularly for any damage, mildew and mold. If you catch these issues early you can save money on repairs in the future.
The sash is the interior framing that can be moved vertically up or down in windows that are open. This article will teach you how to perform easy repairs to your sash.
Weather Stripping
Wood window sashes give a classic aesthetic to your home and, when properly maintained, they will last for many years. However, they can become damaged or degrade as time passes because of exposure to the elements and wear and wear and tear. Thankfully, sash repair experts can restore your windows to their original condition and maintain their appearance for much longer than newer replacement windows.
The first step to sash window repairs is addressing weather stripping. It's found on both the sash and frame. If it's damaged or worn out, it can cause drafts, as well as other issues. Start by identifying the window's brand and the date of manufacture for the glass (etched on the glass's corners or the aluminum spacers between panes). Remove the sash and mark its width and height so that you can purchase replacement weather stripping that matches.
Then, you can remove the sash from its holder and place it on an even surface that allows you to access all four sides. If double glazing Chatham is double-hung, you'll need to take off the weights and their ropes that should have fallen into the intended pocket in the jamb liner. After removing the sash with the utility knife, you can remove the old weather stripping by hand or with the putty blade.
Once the sash has been cleaned, you can replace the parting stops. These are long pieces that divide the sashes. Pam likes to replace them with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard, however you could also use scrap wood.
After removing the parting stop and cutting it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound with your putty knife and let it dry for at least a few days. 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 look.
Sash Hardware
The hardware that holds the window sashes can wear out over time and use. This could result in a door or a window 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're having difficulty opening the sash, spray some oil into the jamb channel. Then, slide the sash open to see if that fixes the problem. If not, the problem is most likely due to the balance of the sash and you'll need to remove the sash to gain access to the hardware.
The ideal situation is for window sashes to move open and shut with minimal effort but this can be a difficult task if the weights become worn or if the sash meeting rail isn't properly coated. This issue could be caused by a variety of reasons, such as the lack of maintenance or the wrong weight rating for a particular window sash.
If the hinge arms on the window begin to move, this can cause the sash drag and then hit the frame at the opposite corner (Photo 1). To address this issue, first make sure the sash is squarely inserted into the frame's opening and then remove it from the window. If the sash is fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).
Old windows, especially those in older houses, can be difficult to open and close due to sagging hinges and a general lack of energy efficiency. In many instances, a few easy repairs can turn these windows into smooth operators for the first time and save the homeowner cash on energy costs.
In order to make these sash repairs it is essential to have all of the tools needed before you begin. Start by marking the location of the hinge channel on the frame with pencil (Photo 1). This will allow you to get the channel back in the correct position after you've finished. Take the sash off and then remove all hardware including the parting beads, cords, and chains that hold the sash in place. Soften any putty that has been hardened with the help of a heat gun set at medium and equipped with a shield for the nozzle. Remove the old sash, and put it in a labeled bag.
Sash Weights
Whether your window sash repairs are to replace a broken cord or simply to ensure that the windows are functional and functional, replacing worn-out sash weights will improve sash operation and cut down on energy costs. Sash weights consist of heavy iron or lead cylindricals that are contained in a concealed cavity and connected by ropes to the movable window sash. These weights act as counterbalances and allow you to open and shut the window without requiring mechanical or electrical devices. When they fail, sashweights are usually neglected or not used by homeowners.
It's difficult to retrieve a sash-weight that has fallen from the cavity, so you'll want to find one that fits properly. You will also need a new piece of string, a length the sash cord, as well as some sash pulleys to tie the new sash weights to the sash cord.
Older windows made of wood 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 are large on one side and smaller on the other. It is essential to first remove the smaller diameter sides. Sashes that were made later in the century used glue instead of pegs. They can be separated by cutting through the glue line with the help of a knife, and then tapping the mortised part loose with a mallet.
Once the sash has been released, you can remove sash stops and access the pockets for weights. Usually, this is done through an opening at the bottom of each jamb. This hole is then covered by a wooden access panel that can be cut off to let you observe the inner workings of the frame.
After you have the sash stopped and the access panel removed, you will be able to take off the weight of the old sash and replace it with the new. Make sure you weigh the sash prior to you begin, as the weights that were previously used may be different sizes than what you require. Once the new weight has been installed, run the string through the sash pulling mechanism. Then, you can nail the string to the frame, but only leave a few inches of string hanging from the head to allow for future adjustments.
Sash Cords
Most double-hung windows of the past include a chain or cord attached to the weights which helps keep the sashes in balance within the jamb. Over time, these cords can get damaged and render it impossible to raise the windows. A new sash cable can restore the ability to move and lower the sash and keep it in place when it is opened.
To replace sash cords, the first step is to remove the access panels from the jambs. These are usually installed by screws or nails and will need to be removed or moved. You could use a hammer and chisel to remove them but it's best to lay down dust sheets before starting any work.
After removing the access panel, you are able to begin working on the sash. Utilize a flat bar, or chisel to pry the narrow parting beads from their grooves. They are usually wedged in or nailed in, but they can be removed which is why it's worth your time here. If the sash is still in place, pry the mortise and tenon joints free with a screwdriver or hammer, then remove each wood peg. You should now be able to move the sash back and forth freely, although it may require oiling if it seems stiff.
With the sash in an open position Take a measurement of the sash chain to extend from the pulley at the top of the jamb to the sash slot at the bottom. Cut the cord or chain and attach it in the previous step. You can employ a hammer, screws or nails, however nails are less likely to cause damage.
It is recommended to keep the original weights in place unless you have purchased a kit to replace the counterbalance that was previously installed. It's not too expensive to purchase them from a salvage store and they'll be easy to install once you've got the sash opened. Based on the dimensions and shape of your window you may require one or two sashweights in order to keep it open.
