Window Sash Repairs
Sashes for windows must be inspected regularly for signs of mold, mildew and damage. By catching problems before they become serious, you can save money on repairs in the future.
The sash is the internal framing that moves vertically upwards or downwards in windows that open. This article will teach you how to carry out a few simple repairs to sash.
Weather Stripping
Wooden window sashes can give an elegant appearance to your home. They are also sturdy and will last for many years provided they are properly maintained. However, they can become damaged or degraded with time due to exposure or normal wear and tear. Sash repair experts can restore windows back to their original condition and maintain their appearance much longer than replacement windows.
The first step in sash window repair s is addressing weather stripping. It's found on both the sash and frame. If it's worn or loose, out, it can cause drafts and other issues. To fix it, start by determining your window's brand and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Remove the sash and mark its size and width so that you can get new weather stripping that is compatible with the original.
Then, take the sash from its holder, and place it on a flat surface to allow you to access all four sides. If your sash has a double-hung, you'll need to remove the weights and the ropes that go with them, which should have fallen into the intended pocket in the jamb liner. After removing the sash using the utility knife, remove the weather stripping that was left by hand or with the putty blade.
After the sash has been cleared, you can replace the parting stops. These are long pieces that divide the sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. But, you can also use a scrap piece of wood.
After removing the stoppers for parting and cutting them to the desired length and thickness, apply a thin layer of glazing compound over the bottom of the sash. Smooth out the compound using your putty knife, then let it dry for a minimum of a day. After the putty has completely cure it is possible to apply an acrylic latex topcoat. This will protect the putty, and give your sash an updated look.
Sash Hardware
The hardware that supports window sashes can wear out over time and with use. This can result in the window or door that is difficult to open or close. It's important to know that replacing or fixing this hardware is usually easy and affordable. If a sash isn't easy to operate, try spraying some lubrication into the jamb channel then slide it open to see if it solves the issue. If not, the problem is most likely due to the sash balance, and you'll have to take off the sash to gain access to this hardware.
The ideal situation is for window sashes to move open and shut without effort, but this can be an issue if the weights become worn or if the sash meeting rail isn't properly glazed. This issue could be caused by a variety of factors that include a lack of maintenance and an unmatched weight rating.
If the hinge arms on windows begin to slide, this could cause the sash to drag and then hit the frame at the opposite corner (Photo 1). To address 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 is secured to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Then, you can install the new sash (Photo 3).
Due to hinges that are sagging, and a general lack of energy efficiency, windows that are old, especially those in older houses, could be difficult to open and close. Many times it is a matter of making a few minor adjustments that can allow these windows to operate smoothly and help homeowners save money on their energy bills.
To complete these repairs to the sash, it's important to have all of the necessary tools in place before you begin. Mark the hinge channel location on the frame (Photo 1) with pencil. This will help you to put the channel in the right position after you've finished. Remove the sash, and then remove the hardware including the parting beads (Photo 2) and the cords or chains that secure it. A hot gun with nozzle shield and a medium setting will soften any putty that has been hardened. Take off the old sash and place it in a labelled bag.
Sash Weights
Sash weights can be replaced to enhance the efficiency of your window sash and decrease the energy cost. Sash weights are hefty lead or iron cylinders that are enclosed in a concealed cavity and attached to the movable sash by rope. These weights provide counterbalance that allows the window to be opened and closed without the use of electrical or mechanical devices. If they fail, sashweights are usually left unnoticed or disabled by homeowners.
A weight in a sash that has fallen out of the cavity is difficult to recover, so you will want to locate a new one that is suitable for the. You will also require a new piece of string, a length of sashcord and a few sashpulleys to secure the weights you are replacing to the cord.
Older windows made of wood are joined with mortise and tenon joints. Pin punch and hammer can be used to cut off the wood pegs that hold the components together. The majority of these pegs are big on one side and smaller on the other. It is crucial to remove first the smaller diameter sides. Later sashes made use of glue instead of pins. They can be separated with a knife and a mallet.
Once the sash is freed then you can take out the stopper on the sash and get access to the weight pocket. This is typically done by drilling an opening at the bottom of every jamb. The hole is then covered with a wooden access panel that can be cut off so that you can observe the inner workings of the frame.
When the sash has been shut off and the access panel is removed, you can remove the weight you used and replace it. Weigh the sash first to ensure that the weights you've got may not be of the right size. After the new weight has been installed, thread the string through the sash pulling mechanism. Then nail the string to the frame, leaving a few inches of string sticking out from the head to allow for future adjustments.
Sash Cords
Most old double-hung windows have a cord or chain connected to the weights that keeps the sashes in balance within the jamb. Over time, these chains may become damaged and render it impossible to raise the windows. A new sash cord will restore the ability to move the sash upwards and downwards 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 nailed or screwed in and will need to be removed or relocated. You might be able to use a hammer or chisel to remove them but it's best to lay down dust sheets before starting any work.
After the access panel has been removed, you can start working on the sash. Use a flat bar or chisel, to pry the narrow parting beads from their grooves. It is essential to take your time because they are usually stuck or nailed to the floor. If the sash remains in place, break the mortise-and tenon joints using a hammer or screwdriver, then remove each wood peg. The sash should move freely now, but it might require some lubrication to feel less stiff.
With the sash in an open position Take a measurement of the sash chain to extend from the pulley on the top of the jamb to the sash slot at the bottom. Cut the cord/chain and then attach it as described in the previous step. You can use 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 is recommended to keep the original weights for balancing in place. It's not too expensive to purchase them from architectural salvage stores and they will be easy to install once you've got the sash opened. Depending on the dimensions and shape of your window you might need to install one or two sashweights to keep the sash open.
