Window Sash Repairs
Window sashes need to be regularly checked for mold, mildew and damage. By catching problems before they become serious, you can save money on future repairs.
The sash is the interior framing that can be moved vertically up or down in windows that open. This article will teach you how to do simple repairs to sash.
Weather Stripping
Wood window sashes give a classic aesthetic to your home and, when properly maintained, they will last for a long time. However, they can become damaged or degraded with time, due to exposure and normal wear. Sash repair experts can restore windows to their original condition and maintain their beauty longer than replacement windows.
The first step for sash window repairs is addressing weather stripping, which can be found on both the sash as well as the frame. If it's damaged or worn out, it can cause drafts and other issues. Start by identifying the window brand and the manufacturer's date (etched on the corner of the glass, or the aluminum spacers between panes). Then, remove the sash and mark its width and height so that you can locate replacement weather stripping to match.
Then, remove the sash and set it on a work surface to allow access to all four sides. If your sash is double-hung, you'll also need to remove the weights as well as their accompanying ropes that should have fallen into the pocket of the jamb liner. After removing the sash with the utility knife, remove the weather stripping from the old sash by hand or with a putty knife.
After the sash is cleared, you can replace the parting stops. These are long pieces that divide the sashes. Pam likes to replace them with standard 1/2-inch-by 3/4-inch window trim from the lumberyard. However, you can also replace them with scrap wood.
After removing the stoppers for parting and trimming them to your desired length, apply a thin layer of glazing compound on the bottom of the sash. Smooth it out using your putty knife, then let it dry for a minimum of a day. After it has fully dried, apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a new appearance.
Sash Hardware
The hardware that supports the window sashes may wear out over time and with use. This can result in the window or door that is difficult to open or close. It's important to know that replacing and repair of this hardware is typically straightforward and cost-effective. If you're having difficulty opening a sash, spray some lubricant into the jamb channel. Then slide the sash up and 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 remove the sash to gain access to the hardware.
Ideally, window sashes must move open and shut with minimal effort but this can be a difficult task if the weights become worn or if the sash meeting rail isn't properly coated. This problem can be caused by a number of factors, including the lack of maintenance or a mismatched weight rating for a particular window sash.
If the hinge arms of a window begin to slide, this could cause the sash's to drag and eventually land on the frame in the corner opposite the hinge arm (Photo 1). To correct the issue, make sure that the sash is in the proper position within the frame opening and then remove it. If the sash was screwed onto the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash (Photo 3).
Because of sagging hinges and a general lack in energy efficiency, old windows particularly those in older homes, can be difficult to open or close. Sometimes, a few simple fixes can help these windows function smoothly and save homeowners money on their energy bills.
It is crucial to have the tools you require before you begin. Mark the hinge channel location on the frame (Photo 1) using a pencil. This will allow you to get the channel back on position correctly after you've completed. Then, remove the sash, and then remove the hardware, including the parting beads (Photo 2) and the chains or cords which hold it in place. The nozzle shield of the heat gun and medium setting will soften any hardened putty. Remove the old sash, and put it in a bag labeled.
Sash Weights
Sash weights can be changed to enhance the efficiency of your window sash and decrease the cost of energy. Sash weights are hefty lead or iron cylinders enclosed inside a hidden compartment and linked to the moveable the sash with rope. These weights provide counterbalance which allows the window to be shut and opened without the use of electrical or mechanical devices. The sash weights are often ignored or discarded by homeowners, and are turned into scrap when they fail; therefore, you may need to search for replacements.
A weight from a sash that fell out of the cavity is difficult to get back, so you will want to locate a new one that fits properly. You will also need an additional piece of string, a length of sash cord and some sash pulleys to tie the new sash weights to the sash cord.
Mortise and Tenon joints can be used to join older wood windows. Hammers and pins can be used to remove the wood pegs holding the components together. The majority of these pegs have large diameters on one side and a smaller size on the other, which is why it is important to remove the smaller-diameter ones first. Sashes made later in the century used glue instead of pegs. They can be separated by cutting the glue line with an instrument, and then tapping the mortised part loose using mallets.
Once the sash is freed and removed, you can take off the stopper on the sash and get access to the weight pocket. Usually this is accomplished by drilling a hole near 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.
When the sash has been shut off and the access panel is removed, you can take off the old weight and replace it. Be sure to weigh the sash prior to you do this, since the weights that were previously used may be a different size than the one you need. Once window repairs near me is in place then tie a string to it and thread it through the pulley for the sash. Then nail the string to the boxed frame, but leave a few inches of string protruding from the head for future adjustment.
Sash Cords
In the majority of double-hung windows, a cord or chain is affixed to the weights. This helps keep the sashes within the jamb in a balanced manner. Over time, these cords could break, making it impossible to raise the window. A new sash cable will restore the ability to raise and lower the sash and keep it in place when it is opened.
To replace sash cords the first step is to remove the access panels from the jambs. These are usually attached by nails or screws and need to be removed. It may be possible to remove them with an axe or hammer, however, it is best to lay out dust sheets before beginning any work.
After you have removed the access panel, you can begin working on the sash. Take the narrow beads (also called "tie rails") out of their grooves using flat bar or chisel. They are usually wedged in or nailed in, but they can be snipped out and it's worth your time. If the sash is in place, remove the mortise and the tenon joints by using the help of a hammer and pin or screwdriver, then unhook the wood pegs on each piece. The sash should move freely, however it might require some lubrication to feel less stiff.
Measure the length of sash chain/sash cord required to reach the sash slot at the bottom from the pulley at the top of the jamb. Cut the chain or cord and then secure it in the step 6 above. You can either employ a hammer, screws or nails, however nails are less likely to cause damage.
It is recommended to keep the weights that came with the original counterbalance unless you have purchased a kit to replace the counterbalance. They're not costly and simple to install if you purchase them at architectural salvage stores. Based on the size and shape of your window, you might need to install one or two sashweights to keep it open.
