Window Sash Repairs
Window sashes need to be checked regularly for mold, mildew and other damage. You can avoid future repair costs by catching the issues early, before they become too much.
The sash is an interior framing that can be moved vertically either up or down in windows that open. This article will teach you how to perform several simple repairs to sash.
Weather Stripping
Wooden window sashes can give a classic look to your home. They are also durable and last for a long time if they are properly maintained. However, they can become damaged or degraded with time, due to exposure and normal wear and tear. Sash repair experts can restore windows to their original state and keep them looking great much longer than replacement windows.
Weather stripping is the first issue to take care of when fixing sash windows. It is located on both the frame and the sash. If it's loose or worn out, it can lead to drafts and other issues. Start by identifying the window's brand and the glass manufacturer's date (etched on the glass's corner or the aluminum spacers between panes). Then, take the sash off and mark its width and height to find the appropriate weather stripping replacement to match.
Then, you can remove the sash from its holder and place it on flat surfaces to allow you to reach all four sides. If your sash was double-hung, you must remove the weights with their ropes that should be buried inside the jamb lining. After removing the sash using the utility knife, take off the weather stripping from the old sash by hand or using a putty knife.
Once the sash has been cleared, you can replace the stoppers that separate the two sashes. They are long pieces of wood that are used to separate the two sashes. Pam prefers to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you can also replace them with scrap wood.
After removing the stopper and cutting it to length, apply a thin coat of glazing compound over the bottom of the sash. Smooth the compound with your putty tool, and allow it to dry for at least a day. When the putty is fully cure and dried, you can apply an acrylic latex topcoat. This will protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that supports window sashes can wear out with time and use. This could result in windows or doors that is difficult to open or close. The good news is that fixing and replacing this hardware is typically relatively easy and affordable. If you are having trouble opening a sash, spray some lubricant into the jamb channel. Then slide the sash out to see if that fixes the issue. If not, the issue is most likely due to the balance of the sash and you'll need to take out the sash to gain access to the hardware.
Sashes for windows should be able to be able to open and close with minimal effort. However, this may be a challenge if the weights have been worn out or the sash-to rail connecting rail isn't properly covered with. This problem can be due to many factors, including an absence of maintenance or a mismatched weight rating.
If the hinges on windows begin to slide, this can cause the sash drag and eventually hit against the frame at the opposite corner (Photo 1). To fix the problem, make sure that the sash is centered in the frame opening and then take it off. If the sash was screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).
Due to sagging hinges, and a general deficiency in energy efficiency, old windows particularly those in older homes, can be difficult to open and close. Sometimes it is a matter of making a few minor adjustments that can help these windows function smoothly again and help homeowners save money on energy costs.
It is crucial to have the tools needed before you begin. Mark the hinge channel location on the frame (Photo 1) using a pencil. This will allow you to put the channel in the proper place when you are 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 can soften any hardened putty. Remove the old sash and put it in a bag that is labeled.
Sash Weights
Whether your window sash repairs are to replace a damaged cord or simply to ensure that the windows are functional and functional, replacing worn-out sash weights will improve sash operation and reduce the energy cost. Sash weights are heavy, lead or iron cylinders, which are enclosed in a concealed cavity and connected to the movable sash by a rope. They function as counterbalances, which allows you to open and close the window 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 have to locate replacements.
A weight from a sash that fell out of the cavity is difficult to retrieve, so you will want to find a replacement that fits properly. You will also require a new piece of string, a length the sash cord, as well as some sash pulleys to tie the new sash weights onto the sash cord.
Older wood windows are joined with mortise and tenon joints. Hammers and pins can be used to take out the wood pegs that hold the parts together. The majority of these pegs are large on one side, and smaller on the other. It is important to remove first the smaller diameter sides. Later sashes made use of glue instead of pins. They can be cut by using a knife and mallet.
After the sash has been removed and removed, you can take off the sash stop and gain access to the weight pocket. Usually this is accomplished by drilling a hole near the bottom of each jamb. The hole is then covered with a wooden panel that can be removed to reveal the interior workings.
After the sash has been stopped and the access panel removed, you will be able to remove the old sash weight and replace it with new. Weigh the sash first, as the weights you have may not be of the right size. Once window repair is installed, tie a string to it and thread it through the pulley of the sash. Then nail the string to the boxed frame, leaving a few inches of string protruding from the head for future adjustments.
Sash Cords
In most old double-hung window the chain or cord is attached to the weights. This supports and keeps the sashes within the jamb level. Over time these cords can break, making it difficult to raise the window. A new sash cable can restore the ability to raise 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 usually screwed or nailed in and require removal. You may be able to use a hammer and chisel to remove them however, it is always best to lay down dust sheets before starting any work.
After removing the access panel, you are able to begin to work on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves using the chisel or flat bar. It is essential to take your time, as these are often stuck or nailed to the floor. If the sash remains in place, break the mortise-and-tenon joints out using a hammer or screwdriver, then remove each wood peg. The sash should be able to move freely now, but it may need some lubrication in order to feel less stiff.
With the sash open Take a measurement of the sash chain to extend from the pulley at the top of the jamb to the sash slot in the bottom. Cut the chain or cord and secure it as in Step 6 above. You can use nail, hammer or screws. However nails are less likely to cause damage.
It's best to leave the original weights if you've purchased a kit to replace the old counterbalance. They're not costly and are easy to install if purchased them from salvage shops for architectural use. Depending on the size and shape of your window, you may require one or two sashweights to keep it open.
