Window sashes need to be checked regularly for mold, mildew and other damage. By catching these problems early you can save money on future repairs.
The sash is an interior frame that is able to move upwards and downwards in windows that open. This article will teach you how to do simple sash repairs.
Weather Stripping
Wooden window sashes can give an elegant look to your home. They are also sturdy and last for a long time provided they are properly maintained. However, they may become damaged or degrade as time passes because of exposure to the elements and normal wear and wear and tear. However, sash repair experts can restore your windows back to their original condition and keep them looking great for a longer period of time than replacement windows.
The first step for repair sash windows is to address weather stripping, which can be found on both the sash as well as the frame. If it's loose or worn out, it can lead to drafts, as well as other issues. To fix it, start by determining the brand of your window and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Remove the sash, and mark its width and height so you can get new weather stripping that is compatible with the original.
Then, remove the sash and set it on a table so you can access all four sides. If the sash is double-hung, you'll need to take off the weights and their ropes that should have fallen into the pocket that was intended to be in the jamb liner. Once you've removed the sash using a utility knife, you can use it to remove the weather stripping from the corners, and then take it off by hand or using a putty knife.
Once the sash is clear it is time to replace the parting stops. They are long pieces of wood that divide the two sashes. Pam prefers to use the standard 1/2-inch by 3/4-inch window trim from the lumberyard. But, you can substitute a scrap piece of 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, then let it dry for a minimum of a day. After the putty has completely cured and dried, you can apply a topcoat of acrylic latex. This coating will protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that supports window sashes is prone to wearing out from the wear and tear of use and the result could be a door or window that isn't able to open or close easily. The good news is that repairing and replacing this hardware is usually very simple and cost-effective. If you are having trouble opening the sash, spray some grease into the jamb channel. Then, you can slide the sash open to see if this resolves the problem. If not, the issue is likely to be with the balance of the sash and you'll need to take out the sash to access the hardware.
Ideally, window sashes must move open and shut with very little effort, but this is difficult when the weights are worn or if the sash's meeting rail isn't properly coated. This issue can be caused by a number of reasons, such as lack of maintenance or by the wrong weight rating for a particular window sash.
If the hinges on a window begin to sag this can cause the sash drag and then hit the frame in the opposite corner (Photo 1). To remedy the issue make sure the sash is aligned in the frame's opening and take it off. If the sash was attached to the hinge arm, take it off the hinge and replace it. (Photo 2). Then, put in the new sash (Photo 3).
Windows that are old, especially in older homes, can be difficult to close and open due to hinges that are sagging and a general lack of energy efficiency. Many times just a few easy fixes can help these windows function smoothly and save homeowners money on their energy bills.
It is important to have the tools you need before you start. Begin by marking the position of the hinge channel on the frame with a pencil (Photo 1). This will allow you to place the channel in the proper place when you are finished. Then, remove the sash, and then remove the hardware including the parting beads (Photo 2) and the chains or cords that hold it in place. Heat gun with nozzle shield and a medium setting can soften any hardened putty. Take off the old sash and keep it in a bag with a label.
Sash Weights
If your window sash repairs are to replace a broken cord or just to ensure that the windows are functional and functional, replacing worn-out weights on sash can improve sash operation and help reduce the energy cost. Sash weights are composed of iron or lead cylinders that are encased inside a concealed cavity, and attached by a rope to the movable window sash. These weights act as counterbalances, allowing you to open and close the window without requiring mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners and turned into scrap when they fail. Consequently, you may need to search for replacements.
A weight in a sash that has fallen out of the cavity is difficult to recover It is therefore important to find a replacement that fits properly. You will also require a fresh piece of string, a length sashcord and some sashpulleys to tie the new weights to the cord.
Older windows made of wood are joined by mortise and tenon joints. Pin punch and hammer can be used to take out the wood pegs holding the components together. The majority of these pegs are big on one side and smaller on the other. It is crucial to remove first the smaller diameter sides. Sashes made later in the century made use of glue instead of pegs and can be separated by cutting through the glue line using an instrument, and then tapping the mortised section loose with a mallet.
Once the sash has been released, you can remove the sash stops and gain access to the pockets for weights. Usually this is accomplished by drilling an opening in the bottom of each jamb. The hole is then covered with an unfinished wooden panel that can be removed to reveal the interior workings.
After the sash has been stopped and the access panel removed, you'll be able to remove the weight of the old sash and replace it with the new. Be sure to weigh the sash prior to you do this, as the old weights may be different in size from what is needed. Once the new weight has been installed, thread an appropriate length of string through the pulling mechanism. Then nail the string to the frame, leaving a few inches of string hanging from the head for future adjustments.
Sash Cords
The majority of double-hung windows with a history have a cord or chain attached to the weights that helps keep the sashes level within the jamb. Over time, these cords could break, making it impossible to raise the window. A new sash cord can restore the ability to move the sash upwards and downwards and hold it in position when it is opened.
The first step in replacing sash cords is to find and remove the access panels in the jambs. They are usually nailed or screwed in and will require to be removed or relocated. You could use a hammer and chisel to remove them but it's best to lay down dust sheets before starting any work.
After you have removed the access panel, you are able to begin to work on the sash. Utilize a flat bar or chisel to pull the tiny parting beads from their grooves. It's important to take your time because they are usually wedged or nailed in place. If the sash remains in place, break the mortise-and-tenon joints out with a screwdriver or hammer, then remove each wood peg. The sash should be able move around freely now, however it may require some lubrication to feel less stiff.
Take a measurement of the length of sash cord/chain required to reach the sash slot on the bottom from the pulley on the top of the jamb. Cut the cord or chain and fix it as described in Step 6 above. You can use a hammer and screws or nails, but 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 weights for balancing in place. They are not expensive and easy to install if you buy them at architectural salvage stores. Based on the dimensions and shape of your window you may require one or two sashweights to keep the sash open.
