Window Sash Repairs
Window sashes need to be regularly checked for mold, mildew, and damage. By catching these problems early, you can save money on future repairs.
The sash is the internal framing that moves vertically up or down in windows that open. This article will teach you how to perform easy repairs to your sash.
Weather Stripping
Wood window sashes add the classic look to your home and, when properly maintained, can last for many years. However, they can be damaged or degrade over time due to exposure to the elements and wear and tear. Sash repair specialists can restore windows to their original condition and maintain their appearance longer than replacement windows.
The first step for sash window repairs is addressing weather stripping. It's found on both the sash as well as the frame. It can cause drafts if it's worn or loose. Begin by identifying the window's brand and the glass manufacturer's date (etched on the glass's corner or the aluminum spacers 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 the 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 also need to remove the weights as well as their ropes that should have fallen into the pocket that was intended to be in the jamb liner. After you have removed the sash using the utility knife, remove the weather stripping that was left by hand or with a putty blade.
After the sash has been cleared it is time to replace the parting stops. These are long pieces of wood that 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 stoppers for parting and trimming them to the desired length then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound with your putty knife, and then let it dry for at least a day. Once the putty has fully dried it is possible to apply an acrylic latex topcoat. This will protect the putty and give your sash a modern look.
Sash Hardware
The hardware that supports windows sashes can become worn out over time and use. This could lead to windows or doors that is difficult to open or close. It's a good idea to know that replacing and repairing this hardware is often straightforward and cost-effective. If a sash becomes difficult to operate try spraying oil into the jamb channel and then slide it open to see if that fixes the problem. If the issue persists it's likely the sash balance. You will need to take off the window sash to reach this hardware.
Window sashes need 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 meeting rail is not properly coated. This can be due to many factors such as an absence of maintenance or a mismatched weight rating.
If the hinge arms of a window are beginning to slide, this could cause the sash's to drag and eventually land on the frame in the corner that's directly opposite the hinge arm (Photo 1). To correct the issue make sure the sash is in the proper position within the frame opening, and then remove it. If the sash is secured to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).
Windows that are old, especially in older houses, can be difficult to open and close due to hinges that are sagging and general inefficiency. Many times it is a matter of making a few minor adjustments that can allow these windows to operate smoothly again and help homeowners save money on energy costs.
It is important to have the tools you require before you begin. Start by marking the location of the hinge channel on the frame using pencil (Photo 1). This will make it easier to put the channel in the correct location after you've completed. Remove the sash, and remove all the hardware including the parting beads, cords, and chains that hold the sash in place. The nozzle shield of the heat gun and a medium setting will soften any putty that has been hardened. Remove the old sash, and store it in an bag that is labeled.
Sash Weights
If your window sash repairs are to replace a broken cord or to ensure that the windows are functional, replacing worn out weights on sash can improve sash operation and help reduce energy costs. Sash weights are heavy, lead or iron cylinders enclosed inside a hidden compartment and linked to the moveable window sash using a rope. They function as counterbalances, which allows you to open and shut the window without having to use mechanical or electrical devices. When they fail, sashweights tend to be ignored or disabled by homeowners.
A weight in a sash that has fallen out of the cavity is difficult to recover It is therefore important to find a new one that fits properly. You will also require an additional piece of string, a length the sash cord, as well as some sash pulleys to connect the new sash weights to the sash cord.
window repairs near me and Tenon joints are used to join old wood windows. The wood pegs that keep the parts together can be removed with the use of a pin punch and hammer. The majority of them are large on one side, and smaller on the other. It is crucial to remove first the smaller diameter sides. Sashes that were made later in the century made use of glue instead of pegs and can be separated by cutting the glue line with a knife, then tapping the mortised section loose using a mallet.

Once the sash has been released, you can remove the stops on the sash and get access to the pockets for weights. Usually it is done by drilling a hole near the bottom of each jamb. This hole is then covered by an access panel made of wood that can be ripped off to allow you to view the inside of the frame.
Once you have the sash stopped and the access panel removed, you will be able to take off the weight from the sash and replace it with the new. Be sure to weigh the sash first because the weights you have might not be the correct size. Once the new weight is installed, you can thread the string through the sash pulling mechanism. Then nail the string to the boxed frame, but leave a few inches of string hanging from the head to allow for future adjustments.
Sash Cords
The majority of double-hung windows with a history come with a chain or cord attached to the weights that supports and keeps the sashes level within the jamb. Over time, these cords can get damaged and make it difficult to raise the windows. A new sash cord will give you the ability to move the sash up and down and keep it in place when it is opened.
The first step to replace sash cords is to locate and remove the access panels within the jambs. They are typically screwed or nailed into and must be removed. You could use a hammer or chisel to remove them, but it's always better to lay down dust sheets before starting any work.
After the access panel has been removed, you can start working on the sash. Utilize a flat bar or chisel to pry the small parting beads from their grooves. It's important to take your time because they are usually wedged or nailed in place. If the sash is still in place, pull the mortise and tenon joints free using a hammer or screwdriver and then take out each wood peg. You should be able to move the sash back and forth freely, although it might require oiling if it seems stiff.
Measure the length of sash cord/chain required to reach the sash slot on the bottom of the pulley on the top of the jamb. Cut the chain or cord and secure it as in Step 6 above. You can either employ a hammer, screws or nails, but nails are less likely to cause damage.
If you don't have an upgrade kit to replace the old counterbalance system, it's best to keep the original weights for balancing in place. It's not expensive to buy them from a salvage store and they'll be easy to install once you've got the sash opened. Based on the size and shape of your window, you may require one or two sashweights to keep it open.
