Window Sash Repairs
Regularly inspect the window sashes for any damage, mildew and mold. You can avoid the cost of repairs in the future by catching the issues early on before they get out of hand.
The sash is an internal frame that is able to move upwards and downwards in windows that open. This article will teach you how to perform several simple repairs to sash.
Weather Stripping
Wood window sashes give a classic aesthetic to your home. If properly maintained, they will last for a long time. However, they may become damaged or degraded as time passes due to exposure to elements and normal wear and wear and tear. Fortunately, sash repair specialists can restore your windows back to their original condition and maintain their appearance for much longer than newer replacement windows.
Weather stripping is the primary issue to take care of when fixing windows that have sash. It's on both the frame and the sash. If it's damaged or worn out, it could cause drafts and other problems. Begin by identifying the window's brand and the date of manufacture for the glass (etched on the glass's corners or the aluminum spacers between panes). Then, remove the sash and mark its width and height to find the appropriate weather stripping replacement to match.
Then, remove the sash from its holder, and place it on an even surface that allows you to access all four sides. If the sash is double-hung, take out the weights using their ropes that should be buried inside the jamb lining. After you have removed the sash using the utility knife, remove the weather stripping that was left by hand or with the putty blade.
After the sash has been cleared, you can replace the stoppers that separate the two sashes. These are long pieces of 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. However, you can also replace them with scrap wood.
After removing the stopper for the parting and cutting it to length and then apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound with your putty knife and let it dry for at least a few days. Once the putty has fully cured and dried, you can apply an acrylic latex topcoat. This will protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that holds window sashes is susceptible to wear and tear from age and use, and the result can be a door or window that won't open or close easily. It's a good idea to know that replacing or fixing this hardware is usually simple and inexpensive. If you are having trouble opening a sash spray some grease into the jamb channel. Then slide the sash up and open 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.
Sashes for windows should be able to open and close with little effort. However, this may be difficult if weights are worn out or the sash connecting rail isn't coated. This issue could be caused by a variety of factors, including the lack of maintenance or a mismatched weight rating.
If the hinge arms of a window are beginning to lose their elasticity, this could cause the sash's to drag and eventually strike the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To remedy the issue make sure the sash is centered in the frame's opening and remove it. If redirected here has been screwed to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).
Old windows, particularly those in older houses, can be difficult to open and close, due to sagging hinges and general lack of energy efficiency. In many instances, a few minor repairs can turn these windows into smooth operation for the first time and save the homeowner cash on energy costs.
It is essential to have the tools you require before you begin. Start by marking the location of the hinge channel on the frame using pencil (Photo 1). This will allow you to get the channel back in position correctly after you've completed. Remove the sash and then remove all hardware, including the parting beads cords, chains, and cords that keep the sash in place. The nozzle shield of the heat gun and medium setting will soften any hardened glue. Remove 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 to keep the windows functional by replacing worn out weights on sash can improve sash operation and cut down on energy costs. Sash weights are made of iron or lead cylinders that are enclosed in a hidden cavity and are connected via ropes to the movable window sash. These weights function as counterbalances, which allows you to open and shut the window without having to use mechanical or electrical devices. When they fail, sashweights are often neglected or not used by homeowners.
A weight from a sash that fell out of the cavity is difficult to retrieve It is therefore important to find a replacement that is suitable for the. You will also require a new piece of string, a length sashcord and a few sashpulleys to secure the new weights to the cord.
Mortise and Tenon joints can be used to join windows made of older wood. Hammers and pins can be used to take out the wood pegs that hold the components together. The majority of them have a large diameter on one side and a smaller diameter on the other side, so it is crucial to take out the small-diameter sides first. Later sashes used glue instead of pins. They can be cut by using a knife and mallet.
After the sash is released, you can remove stops on the sash and get access to the weight pockets. This is usually done through an opening in the bottom of each jamb. This hole is then covered by an access panel of wood which can be removed to allow you to observe the inner workings of the frame.
Once the sash is stopped and the access panel has been removed, you can remove the old weight and replace it. Make sure you weigh the sash prior to you do this, since the old weights may be different sizes than what is needed. Once the new weight is installed, you can thread the string through the sash pulling mechanism. Then, attach the string to the boxed frame. Leave a few inches of space at the end of the string for future adjustments.
Sash Cords
Most double-hung windows of the past include a chain or cord attached to the weights which helps keep the sashes in balance within the jamb. As time passes, these cords may become damaged and render it impossible to raise the windows. A new sash cord will restore the ability to move the sash upwards and downwards 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 usually screwed or nailed in and require removal. You could employ a hammer and chisel to prise them off, but it's always better to lay down 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 pull the tiny parting beads out of their grooves. It is important to take your time as they're often placed in a wedge or nail. If the sash remains in place, pry the mortise-and-tenon joints out with a screwdriver or hammer and then remove each wood peg. The sash should be able to move freely, however it may need some lubrication to feel less stiff.
Take a measurement of the length of sash cord/chain needed to reach the sash slot at the bottom from the pulley located at the top of the jamb. Cut the cord or chain and attach it as described in the step 6 above. You can use either a hammer, nails, or screws. However, nails are less likely to cause damage.
If you don't have an upgrade kit to replace the old counterbalance system it is recommended to keep the original balancing weights in place. It's cheap to purchase them from a salvage store and they'll be easy to install once you have the sash unlocked. Depending on the dimensions and shape of your window, you might need to install one or two sashweights to keep it open.
