Window sashes must be regularly checked for mold, mildew and damage. You can reduce the cost of repairs in the future by catching these issues early on, before they become too much.
The sash is the internal frame that is vertically moved either up or down in windows that are open. This article will teach you how to perform simple repairs to sash.
Weather Stripping
Wood window sashes provide a classic aesthetic to your home. When properly maintained, can last for years. However, they can be damaged or degrade as time passes due to exposure to elements and normal wear and tear. Sash repair timber windows specialists can restore windows to their original state and maintain their beauty much longer than replacement windows.
The first step in repair sash window damage is to fix weather stripping, which is found on both the sash as well as the frame. It could cause drafts if damaged or is loose. Start by identifying the brand of window and the manufacturer’s date (etched on the corner of the glass or on the aluminum spacers between panes). Remove the sash, and mark its size and width so that you can purchase new weather stripping that is compatible with the original.
Then, you can remove the sash from its holder and place it on a flat surface to allow you to see all four sides. If the sash is double glazing window repair-hung, you must remove the weights using their ropes that should have fallen into the pocket within the jamb lining. After removing the sash using the utility knife, you can remove the old weather stripping by hand or using a putty knife.
After the sash is cleared, you can install parting stops. These are long pieces of 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. However, you can also use a piece of scrap wood.
After removing the stopper and trimming it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using a putty tool and allow it to dry for at least one day. Once it’s fully cured, apply a top coat of acrylic latex paint. This will protect the putty and give your sash an updated look.
Sash Hardware
The hardware that supports window sashes is susceptible to wear and tear from time and usage, and the result can be a window or door that isn’t able to open or close easily. The good news is that repairing and replacing this hardware is typically relatively easy and affordable. If a sash becomes difficult to operate, try spraying some oil into the jamb channel, and then slide it open to see if this fixes the problem. If not, the issue is likely to be with the sash balance and you’ll need to remove the sash to access this hardware.
Ideally, window sashes must move open and shut without effort, but this is difficult if the weights become worn or if the sash meeting rail isn’t properly coated. This issue can be caused by a variety of things, such as the lack of maintenance or the wrong weight rating for the specific window sash.
If the hinge arms on windows begin to slide, this could cause the sash to drag and then hit the frame in the opposite corner (Photo 1). To fix this problem, first ensure that the sash is firmly seated in the opening of the frame and then take it out of the window. If the sash has been attached to the hinge arm, remove the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).
Because of sagging hinges and a general lack in energy efficiency, windows that are old, especially those in older homes, can be difficult to open and close. In many instances, a few minor repairs can transform these windows into smooth operation and save homeowners cash on energy costs.
It is important to have the tools you require before you start. Begin by marking the location of the hinge channel on the frame using pencil (Photo 1). This will help you to position the channel in the right location after you’ve completed. Remove the sash and remove the hardware, including the parting beads (Photo 2) and the cords or chains that secure it. Heat gun with nozzle shield and a medium setting will soften any hardened putty. Take off the old sash and store it in an bag with a label.
Sash Weights
Whether your window sash repairs are to replace a broken cord or just to keep the windows functional and functional, replacing worn-out weights for sash will improve its operation and reduce energy costs. Sash weights are made of iron or lead cylindricals that are contained in a concealed cavity and attached by ropes to the movable window sash. These weights act as counterbalances, allowing you to open and shut the window without the need for mechanical or electrical devices. If they fail, sashweights are often neglected or not used by homeowners.
It is difficult to recover an sash-weight which has fallen from the cavity, so you’ll want to find one that fits correctly. You will also require an additional 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.
Older wood windows are joined with mortise and tenon joints. The wood pegs holding the components together can be removed with a pin punch and hammer. The majority of them have an enormous diameter on one side and a smaller diameter on the other, which is why it is important to remove the small-diameter sides first. Later sashes made use of glue instead of pins. They can be separated with a knife and mallets.
After the sash has been removed, you can remove the sash stop and access the weight pocket. This is usually done through tiny holes in the bottom of each jamb. This hole is covered by an access panel of wood which can be removed to allow you to view the inside of the frame.
Once you have the sash stopped and the access panel removed, you will be able to take off the old sash weight and replace it with new. Make sure you weigh the sash prior to you begin, as the old weights may be a different size than what is needed. After the new weight is in place you can tie a string around it and thread it through the sash pulley. Then, you can nail the string to the frame, leaving a few inches of string protruding from the head to allow for future adjustments.
Sash Cords
In most old double-hung window, a chain or cord 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 difficult to raise the upvc window repair. A new sash cable can restore the ability to move and lower the sash and ensure it stays in place when it is opened.
To replace sash cords the first step is to remove the access panels from the jambs. They are usually attached by nails or screws and need to be removed. It is possible to remove them using the hammer or chisel but it is always best to lay out dust sheets before starting any work.
Once the access panel is removed, you can begin working on the sash. Use a flat bar or chisel to pry the narrow parting beads out of their grooves. These are often wedged in or nailed but can be prised free, so it’s worth taking your time here. If the sash remains in place, break the mortise and the tenon joints by using pin punch and hammer or screwdriver, then remove the wood pegs that are on the components. It should now be possible to move the sash around without difficulty, though it may require oil if it feels stiff.
Take a measurement of the length of sash cord/chain required to reach the sash slot on the bottom of the pulley located at the top of the jamb. Cut the chain or cord and then attach it as described in Step 6 above. You can use either a hammer, nails or screws. However, nails are less likely to cause damage.
It is recommended to keep the original weights in place unless you’ve purchased a kit that will replace the old counterbalance. They’re not expensive and easy to install if you buy them from architectural salvage stores. Depending on the size of your window, two or three sash weights could be needed to keep the sash in an open position.
