Window Sash Repairs
Regularly inspect the window sashes for any damage, mildew and mold. You can reduce future repair costs by catching these issues early on before they get out of hand.
The sash is the interior framing that can be moved vertically either up or down in windows that are open. This article will teach you how to carry out a few simple sash repair.
Weather Stripping
Wood window sashes provide the classic look to your home. If properly maintained, they will last for
window repairs many years. However, they can be damaged or deteriorate in time due to exposure to elements and wear and tear. Sash repair experts can restore windows 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 as well as the frame. It can cause drafts if it's damaged or is loose. 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). Take the sash off and mark its size and width so that you can find a new weather stripping that is compatible with the original.
Then, remove the sash and place it on a table so you can access all four sides. If the sash is double-hung, take out the weights with their ropes that should have fallen into the pocket inside the jamb lining. After removing the sash using the utility knife, take off the weather stripping from the old sash by hand or with a putty blade.
When the sash is clean it is time to replace the parting stops. These are long pieces wood that divide the two sashes. Pam prefers standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. But, you can also substitute with a scrap piece of wood.
After removing the stopper for the parting and cutting it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using a putty knife, and let it dry at least a day. Once it's fully cured then apply a top coat of acrylic latex paint. This will protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that supports
upvc window repair sashes may wear out over time and with use. This could result in a door or a window that is difficult to open or close. The good news is that repairing and replacing this hardware is usually very simple and cost-effective. If you're having difficulty opening a sash spray some grease into the jamb channel. Then, slide the sash open to see if this resolves the issue. If not, the problem is most likely due to the sash balance, and you'll need to take out the sash in order to access this hardware.
Window sashes should open and close with little effort. However, this may be difficult if the weights are worn out or the sash-to rail connecting rail isn't properly glazed. This issue could be caused by a variety of factors, including insufficient maintenance or an incorrect weight rating for the specific window sash.
If the hinge arms on windows begin to slide, this can cause the sash drag, and then eventually to hit the frame at the opposite corner (Photo 1). To remedy the issue make sure the sash is centered in the frame opening, and then take it off. If the sash is secured to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Next, install the new sash (Photo 3).
Windows that are old, especially in older homes, may be difficult to open and close, due to hinges that are sagging and a general inefficiency. In many instances, a few minor repairs can transform these windows into smooth operators again and save the homeowner cash on energy costs.
It is important to have the tools needed before you start. Mark the hinge channel location on the frame (Photo 1) using pencil. This will allow you to place the channel in the right location after you've completed. Remove the sash, and remove all the hardware, including the parting beads, cords, and chains that help to hold the sash. The nozzle shield of the heat gun and medium setting will soften any hardened glue. Remove the old sash and store it in a bag labeled.
Sash Weights
Sash weights can be changed to enhance the efficiency of your window sash and reduce the energy cost. Sash weights are composed of heavy iron or lead cylinders that are enclosed in a concealed cavity and connected by ropes to the moveable window sash. They are counterbalancers that allows the window to be opened and closed without using mechanical or electrical devices. If they fail, sashweights are often neglected or not used by homeowners.
It's not easy to retrieve a sash-weight that has fallen from the cavity, so you'll want to find one that fits properly. You will also require a fresh piece of string, a length sashcord and a few sashpulleys to secure the weights you are replacing to the cord.
Older wood windows are joined with mortise and tenon joints. The wood pegs that keep the parts together can be removed by a pin punch and hammer. The majority of these pegs have an enormous diameter on one side and a smaller size on the other side, so it is crucial to take out the smaller-diameter sides first. Later sashes made use of glue instead of pins. They can be separated by using a knife and mallets.
After the sash has been removed, you can remove the stopper on the sash and get access to the weight pocket. Usually it is done by drilling a hole near the bottom of each jamb. The hole is then covered with an access panel made of wood which can be removed so that you can see the inner workings of the frame.
Once you have the sash stopped and the access panel removed, you'll be able to remove the old sash weight and replace it with the new. Be sure to weigh the sash first to ensure that the weights you've got may not be of the right size. After the new weight is installed, you can thread the string through the sash pulling mechanism. Then, you can attach the string to your boxed frame. Leave a few inches protruding at the top of the string for future adjustments.
Sash Cords
In the majority of double-hung windows the chain or cord is connected to the weights. This keeps the sashes within the jamb balanced. As time passes, these cords can become damaged and render it impossible to raise the windows. A new sash cord will restore the ability to move the sash up and down and will keep it in its place when it is opened.
The first step in replacing sash cords is to locate and remove the access panels in the jambs. They are typically screwed or nailed in and require removal. It may be possible to remove them using a hammer or chisel, however, it is best to lay out dust sheets prior to beginning any work.
After the access panel has been removed, you can begin working on the sash. Utilize a flat bar or chisel to pull the narrow parting beads from their grooves. They are usually wedged in or nailed in, but they can be removed and it's worth your time. If the sash remains in place, break the mortise and tenon joints with pin punch and hammer or screwdriver, then remove the wood pegs that are on the components. You should be able to move the sash around without difficulty, though it may require lubrication if it feels stiff.
Take a measurement of the length of the sash chain or sash cord needed to reach the sash slot at the bottom from the pulley located at the top of the jamb. Cut the cord/chain and then fix it as described in Step 6 above. You can use either a hammer, nails or screws. However, nails are less likely to cause damage.
Unless you've bought a kit that replaces the old counterbalance system, it is recommended to keep the original balancing weights in place. They're not costly and are easy to install if you purchase them from architectural salvage stores.
