Make sure to check the sashes of your windows regularly for signs of damage, mildew and mold. You can save the cost of repairs in the future by catching the issues in the early stages, before they become too much.
The sash is the interior frame that is vertically moved upwards or downwards in windows that are open. This article will show you how to make several simple repairs to sash.
Weather Stripping
Wooden window sashes can give an elegant appearance to your home. They are also sturdy and will last for many years provided they are properly maintained. However, they may become damaged or degrade over time because of exposure to the elements and normal wear and tear. Fortunately, sash repair specialists can restore your windows to their original condition and keep them looking great for longer than replacement windows.
The first step in repair sash windows is to address weather stripping, which is found on both the sash and frame. If it's worn or loose, out, it could cause drafts and other problems. To fix it, begin by finding your window brand and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Then, remove the sash and mark its width and height to find new weather stripping that matches.
Then, take it off and set it on a work surface so you can access all four sides. If the sash is double-hung, take out the weights using their ropes that should be buried in the jamb lining. After removing the sash using the utility knife, you can remove the weather stripping from the old sash by hand or using a putty blade.
Once the sash has been cleared, you can install parting stops. These are long pieces wood that divide the two sashes. Pam likes to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard, but you can also use scrap wood.
After removing the parting stops and trimming them to the desired length, apply a thin layer of glazing compound to the bottom of the sash. Smooth it out using your putty knife, then let it dry for a minimum of a day. Once it's fully cured, apply a top coat of acrylic latex paint. This will protect the putty and give your sash a fresh look.
Sash Hardware
The hardware that supports window sashes may wear out with time and use. This can result in windows or doors that is difficult to open or close. The good news is that repairing and replacing this hardware is generally quite simple and inexpensive. If a sash is difficult to operate you can try spraying some oil into the jamb channel then open it to see if it resolves the issue. If not, the issue is likely to be with the sash balance, and you'll need to remove the sash in order to access this hardware.
Ideally, window sashes must be able to open and close without effort, but this can be a difficult task when the weights are worn or if the sash's meeting rail isn't properly glazed. This problem can be caused by a variety of reasons, such as lack of maintenance or by a mismatched weight rating for a particular sash.
If the hinge arms on the window begin to move, this could cause the sash to drag, and then eventually to hit the frame in the opposite corner (Photo 1). To fix 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 screwed onto the hinge arm, remove the hinge and replace it. (Photo 2). Then, put in the new sash (Photo 3).
Windows that are old, especially in older houses, can be difficult to close and open due to hinges that are sagging and a general inefficiency. In many instances, a few easy repairs can transform these windows into smooth operation again and save the homeowner money on energy bills.
It is crucial to have the tools you require before you start. Begin by marking the position of the hinge channel on the frame with a pencil (Photo 1). This will help you to put the channel in the right location after you've completed. Take the sash off and take out all the hardware, including the parting beads cords, chains, and cords that help to hold the sash. Soften any putty that has been hardened with the help of a heat gun set at medium and equipped with an nozzle shield. Remove the old sash, and store it in an bag with a label.
Sash Weights
Sash weights can be replaced to improve the performance of your window sash and reduce the energy cost. Sash weights are composed of heavy lead or iron cylinders that are encased in a hidden cavity and are connected via ropes to the moveable window sash. They function as counterbalances and allow you to open and close the window without having to use mechanical or electrical devices. The sash-weights are typically neglected or ignored by homeowners and then turned into scrap when they break; therefore you may have to search for replacements.
It's not easy to retrieve the sash-weight that fell from the cavity, so you'll want to find one that fits properly. You will also need a new piece of string, a length of sash cord, and a few sash pulleys to tie the new sash weights onto the sash cord.
Older windows made of wood are joined with mortise and tenon joints. Pin punch and hammer can be used to remove the wood pegs that hold the components together. Most of these pegs have an enormous diameter on one side and a smaller one on the other, so it is crucial to take out the small-diameter sides first. Sashes 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 mallets.
Once the sash has been removed, you can take off the sash stops and gain access to the pockets for weights. Usually this is accomplished by drilling an opening at the bottom of each jamb. This hole is then covered by a wooden access panel which can be removed to allow you to 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 weight of the old sash and replace it with new. Make sure you weigh the sash before you begin, as the old weights may be a different size than the one you need. Once the new weight is installed you can tie a string around it and then thread it through the pulley for the sash. Then attach the string to the boxed frame, leaving a few inches of string sticking out from the head to allow for future adjustments.
Sash Cords
In the majority of double-hung windows, a chain or cord is attached to the weights. This supports and keeps the sashes in the jamb level. Over time these cords can break, making it impossible to raise the window. A new sash cable will give you the ability to raise and lower the sash and keep it in place when opened.
The first step to replace sash cords is to find and remove the access panels within the jambs. They are usually nailed or screwed in and will require to be removed or moved. You may be able to employ a hammer and chisel to prise them off but it's best to lay down dust sheets prior to commencing any work.
After removing the access panel, you can begin to work on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves with flat bar or chisel. These are often wedged in or nailed in, but they can be removed and it's worth your time. If the sash is in place, remove the mortise and tenon joints with pin punch and hammer or screwdriver, and then take out the wood pegs that are on the components. The sash should be able to move freely now, but it might require some lubrication to feel less 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 then secure it in the previous step. You can either use a hammer and nail or screws, but nails are less likely to cause damage.
It is best to keep the original weights in place unless you've purchased a kit to replace the counterbalance. They're not expensive and easy to install if purchased them from architectural salvage stores. Based on the size and shape of your window you may require one or two sashweights in order to keep it open.
