Window Sash Repairs
Make sure to check the sashes of your windows regularly for damage, mildew, and mold. By catching problems before they become serious you can save money on repairs in the future.
The sash is an internal frame that is able to move upwards and downwards in windows that open. This article will teach you how to carry out a few simple repairs to the sash.
Weather Stripping
Wooden window sashes are a great way to add a classic look to your home. They are also durable and can last many years provided they are properly maintained. However, they can be damaged or degrade in time because of exposure to the elements and normal wear and tear. Sash repair experts can restore windows to their original state and keep them looking great longer than replacement windows.
The first step for repair sash window damage is to fix weather stripping, which can be found on both the sash as well as the frame. It can cause drafts if worn out or loose. Begin by identifying the brand of window and the manufacturer's date (etched on the corner of the glass, 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, take the sash from the holder and place it on a flat surface to allow you to reach all four sides. If your sash has been double-hung, you must remove the ropes and weights that should have fallen into the pocket within the jamb lining. After removing the sash with the utility knife, you can remove the weather stripping from the old sash by hand or using a putty knife.
After the sash is cleared, you can install parting stops. 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 use scrap wood.
After removing the parting stops and trimming 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 at least a few days. When it's completely dried, apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a new look.
Sash Hardware
The hardware that supports window sashes is susceptible to wear and tear from age and use, and the result can be a door or window that won't open or close easily. The good news is that repairing and replacing this hardware is typically very simple and cost-effective. If you are having trouble opening a sash, spray some lubricant into the jamb channel. Then, slide the sash open to see if it resolves the problem. If not, the issue is most likely due to the sash balance and you'll need to take out the sash to gain access to the hardware.
Ideally, window sashes must swing open and closed with minimal effort but this is an issue if the weights become worn or if the sash meeting rail isn't properly glazed. This problem can be due to a variety of factors that include an absence of maintenance or a mismatched weight rating.
If the hinge arms on the window begin to move, this can cause the sash drag and eventually hit against the frame in the opposite corner (Photo 1). To resolve this issue, first make sure the sash fits squarely in the opening of the frame and then remove it from the window. If the sash has been fixed to the hinge arm, take it off the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).
Due to hinges that are sagging, and a general lack in energy efficiency, windows that are old especially in older homes, may be difficult to open and close. In many cases, a few simple fixes can help these windows function smoothly once more and help homeowners save money on their energy bills.
It is essential to have the tools needed before you start. Begin by marking the location of the hinge channel on the frame with pencil (Photo 1). This will help you get the channel back on place correctly when you're finished. Remove the sash and then remove all hardware, including the parting beads cords, chains, and cords that keep the sash in place. Soften any hardened putty using a heat gun set to medium and equipped with an shield to block the nozzle. Remove the old sash and store it in a bag with a label.
Sash Weights
No matter if your window sash repair needs are to replace a broken cord or simply to keep the windows functional and functional, replacing worn-out weights for sash will improve its operation and reduce energy costs. Sash weights consist of heavy lead or iron cylindricals that are contained inside a concealed cavity, and are connected via ropes to the moveable window sash. These weights provide counterbalance that allows the window to be opened and closed without using mechanical or electrical devices. The sash weights are often disregarded or 257634.xyz (

It's difficult to retrieve the sash-weight that fell from the cavity, so you'll want to find one that fits properly. You will also require an additional piece of string, 257634 (
257634.xyz) a length of sash cord and some sash pulleys to tie the new sash weights onto the sash cord.
Older windows made of wood are joined by mortise and tenon joints. The wood pegs holding the parts together can be removed using the use of a pin punch and hammer. The majority of these pegs are big on one side, but 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 separated with a knife and mallets.
After the sash is removed, you can take off the stops on the sash and get access to the weight pockets. This is usually done through a small hole at the bottom of each jamb. This hole is covered with an unfinished wooden panel that can be removed to reveal the interior workings.
After the sash has been stopped and the access panel removed, you'll be able to take off the weight from the sash and replace it with new. Weigh the sash first because the weights you have might not be the correct size. After the new weight has been installed, you can thread the string through the sash pulling mechanism. Then attach the string to the frame, leaving a few inches of string hanging from the head to allow for future adjustments.
Sash Cords
In the majority of old double-hung windows, a chain or cord is attached to the weights. This keeps the sashes of the jamb in a balanced manner. Over time, these cords can get damaged and make it impossible to raise windows. A new sash cord will restore the ability to move the sash up and down and keep it in place when opened.
The first step in replacing sash cords is to find and take out the access panels located in the jambs. These are usually fixed or screwed in and will need to be removed or repositioned. You might be able to use a hammer or chisel for removing them however, it is always best to lay down dust sheets before commencing any work.
After removing the access panel, you are able to begin working on the sash. Make the small parting beads (also known as "tie rails") out of their grooves using the chisel or flat bar. It is essential to take your time as they're often stuck or nailed to the floor. If the sash remains in place, pry the mortise-and-tenon joints out with a hammer or screwdriver, then remove each wood peg. The sash should move around freely now, however it might require some lubrication in order to feel less stiff.
Measure the length of sash chain/sash cord needed to reach the sash slot on the bottom from the pulley located at the top of the jamb. Cut the cord/chain and then secure it in the step 6 above.
