Weather Stripping
Wooden window sashes are a great way to add an elegant look to your home. They are also durable and will last for many years provided they are properly maintained. They can, however, become damaged or degraded with time, due to exposure and normal wear. 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 repairs is addressing weather stripping, which can be found on both the sash and frame. If it's loose or worn out, it can cause drafts, as well as other issues. Begin by identifying the window brand and the date of manufacture for the glass (etched on the glass's corner, or the aluminum spacers between panes). Take the sash off, and mark its size and width so that you can purchase replacement weather stripping that matches.
Next, remove the sash and set it on a work surface to allow access to all four sides. If your sash has been double-hung, take out the weights with their ropes that should fall into the pocket within the jamb lining. After you've removed the sash using a utility knife, you can use it to remove the old weather stripping at the corners. Then, remove it manually or using a putty blade.
After the sash is cleared, you can install parting stops. These are long pieces 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, but you could also use a piece of scrap wood.
After removing the stopper for the parting and trimming it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using your putty tool, and let it dry at least a day. When the putty is fully cure and dried, you can apply a topcoat of acrylic. This will protect the putty and give your sash a modern appearance.
Sash Hardware
The hardware that holds the window sashes can wear out with time and use. This can result in windows or doors that is difficult to open or close. It's important to know that replacing or repair of this hardware is typically easy and affordable. If a sash becomes difficult to operate, try spraying some lubrication into the jamb channel, and then slide it open to see if this resolves the issue. If not, the problem is likely to be with the sash balance and you'll have to take off the sash to gain access to this hardware.
Sashes for windows should be able to open and close without much effort. However, this may be difficult if weights are worn out or the sash meeting rail is not properly covered with. This issue can be caused by a number of factors, including the lack of maintenance or an incorrect weight rating for a particular sash.
If the hinge arms of a window are starting to sag, this can cause the sash's to drag and eventually hit the frame in the corner in the opposite direction of the hinge arm (Photo 1). To resolve this issue, first make sure the sash fits squarely in the frame's opening and then take it out of the window. If the sash is attached to the hinge arm, remove the hinge and replace it. (Photo 2). Install the new sash (Photo 3).
Windows that are old, especially in older homes, can be difficult to close and open due to sagging hinges and a general inefficiency. Sometimes just a few easy fixes can help these windows function smoothly once more and save homeowners money on energy costs.
It is important to have the tools you require before you begin. Mark the location of the hinge channel on the frame (Photo 1) with pencil. This will make it easier to put the channel in the correct place when you are finished. Then, remove the sash and take off the hardware including the beads that separate (Photo 2) and the cords or chains that secure it. Soften any hardened putty with the help of a heat gun set at medium and equipped with a shield for the nozzle. Remove the old sash, and store it in an bag that is labeled.
Sash Weights
Sash weights are able to be replaced to improve the operation of your window sash and decrease the cost of energy. Sash weights consist of heavy lead or iron cylinders that are encased inside a concealed cavity, and are connected via ropes to the movable window sash. These weights provide counterbalance, allowing the window to be closed and opened without the need for mechanical or electrical devices. The sash weights are usually disregarded or disabled by homeowners, and are turned into scrap when they break; therefore you may have to locate replacements.
A weight in a sash that has fallen out of the cavity is difficult to retrieve, so you will want to locate a new one that fits correctly. You will also need a new piece of string, a length the sash cord, as well as some sash pulleys that will tie the new sash weights onto the sash cord.
Mortise and Tenon joints are used to join old wood windows. Pin punch and hammer can be used to take out the wood pegs that hold the parts together. The majority of these pegs have a large diameter on one side and a smaller diameter on the other, so it is crucial to take out the smaller-diameter sides first. Sashes made later in the century made use of 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 mallets.
After the sash is removed, you can take off the sash stops and gain access to the weight pockets. Usually it is done 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 inside workings.
Once the sash is stopped and the access panel has been removed, you can remove the old weight and replace it. First, weigh the sash to ensure that the weights you've got may not be the right size. After the new weight is in place, tie a string to it and thread it through the pulley of the sash. Then, attach the string to your boxed frame. Leave a few inches at the head of the string to allow future adjustments.
Sash Cords
Most old double-hung windows come with a chain or cord attached to the weights which keeps the sashes level in the jamb. As time passes, these cords may become damaged and make it impossible to raise the windows. A new sash cable will restore the ability to raise and lower the sash and keep it in place when it is opened.
The first step to replace sash cords is to locate and remove the access panels in the jambs. They are typically attached by nails or screws and must be removed. It may be possible to remove them using an axe or hammer, but it is always better to lay out dust sheets before beginning any work.
Once the access panel is removed, you can start working on the sash. Utilize a flat bar or chisel to pry the narrow partsing beads out of 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, pry the mortise-and tenon joints using a hammer or screwdriver and then take out each wood peg. You should be able to move the sash around without difficulty, though it will probably need some oiling if it seems stiff.
With the sash in an open position With the sash in an open position, measure the sash chain or cord to extend from the pulley in the top of the jamb to the sash slot on the bottom. Cut the cord/chain and attach it as described in the step 6 above. You can employ a hammer and screws or nails, but nails are less likely to cause damage.
It is recommended to keep the original weights in place unless you've purchased a kit to replace the counterbalance. They're not expensive and simple to install if purchased them from architectural salvage stores. Depending on the dimensions and shape of your upvc window repair, you might need to install one or two sashweights to keep it open.
