window repairs is an internal frame that is able to move vertically up and down in windows that are open. This article will teach you how to perform simple sash repairs.
Weather Stripping
Wooden window sashes can add an elegant appearance to your home. They are also sturdy and will last for many years if they are properly maintained. However, they can be damaged or degraded over time due to exposure or normal wear and tear. Sash repair experts can restore windows back to their original condition and maintain their beauty longer than replacement windows.
The first step in repair sash window damage is to fix weather stripping. It's 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 glass's corner or the aluminum spacers between panes). Then, take the sash off and mark its height and width so that you can locate new weather stripping that matches.
Then, take the sash from the holder and place it on a flat surface to allow you to reach all four sides. If your sash has a double-hung, you'll need to take off the weights and their ropes which should have slipped into the intended pocket in the jamb liner. After removing the sash using the utility knife, take off the weather stripping from the old sash by hand or using the putty blade.
Once the sash is clear it is time to replace the parting stops. These are long pieces that split the sashes. Pam prefers to use the standard 1/2-inch by 3/4 inch window trimming from the lumberyard. However, you can substitute with a scrap piece of 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 at least a few days. When it's completely dried and dried, apply a second coat of acrylic latex paint. This coating will protect the putty and give your sash a new look.
Sash Hardware
The hardware that supports window sashes may wear out over time and with 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 typically relatively easy and affordable. If you are having trouble opening a sash spray some lubricant into the jamb channel. Then, you can slide the sash up and open to see if this resolves the problem. If not, the issue is likely with the sash balance, and you'll have to take off the sash in order to access this hardware.
Window sashes should open and close with little effort. However, this can be difficult if the weights are worn out or the sash-to-rail connecting rail isn't covered with. This issue can be caused by a number of reasons, such as the lack of maintenance or an incorrect weight rating for the specific window sash.
If the hinge arms of a window begin to sag, this can cause the sash to drag and eventually hit the frame in the corner that's directly opposite the hinge arm (Photo 1). To correct the issue ensure that the sash is centered in the frame's opening and take it off. If the sash is secured to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).
Because of sagging hinges and a general deficiency in energy efficiency, older windows especially in older homes, may be difficult to open or close. Many times, a few simple fixes can make these windows operate smoothly and help homeowners save money on their energy bills.
In order to make these sash repairs it is essential to have all of the necessary tools in place before you begin. Begin by marking the location of the hinge channel on the frame with pencil (Photo 1). This will assist you in getting the channel back on position correctly after you've completed. Remove the sash and then remove all hardware including the parting beads, cords, and chains that keep the sash in place. Soften any hardened putty using an electric heat gun set to medium and fitted with a shield for the nozzle. Remove the old sash, and keep it in a bag with a label.
Sash Weights
If your window sash repairs are to replace a damaged cord or to ensure that the windows are functional, replacing worn out weights on sash can improve sash operation and cut down on energy consumption. Sash weights are made of heavy lead or iron cylinders that are enclosed in a hidden cavity and connected by ropes to the movable window sash. They function as counterbalances, allowing you to open and close the window without the need for mechanical or electrical devices. The sash weights are often disregarded or disabled by homeowners and then turned into scrap when they fail. Consequently you might need to search for replacements.
A sash weight that has fallen out of the cavity is difficult to recover It is therefore important to find a new 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 to the sash cord.
Older windows made of wood are joined with mortise and tenon joints. Hammers and pins can be used to cut off the wood pegs holding the components together. The majority of these pegs are big on one side, but smaller on the other. It is crucial to remove first the smaller diameter sides. Later sashes utilized glue instead of pins. They can be cut by using a knife or a mallet.
After the sash is removed and removed, you can take off the stopper on the sash and get access to the weight pocket. Usually it is done by drilling a hole near the bottom of each jamb. The hole is then covered with a wooden panel that can be removed to reveal the inner workings.
After the sash has been stopped and the access panel is removed, you are able to remove the weight that was previously installed and replace it. Make sure you weigh the sash before you do this, since the old weights could be different sizes than the one you need. Once the new weight is in place you can tie a string around it and thread it through the pulley of the sash. Then, you can nail the string to the frame, but leave 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 in a balanced manner. As time passes, these cords may 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 opened.
The first step in replacing cords for sash is to locate and remove the access panels in the jambs. They are usually installed by screws or nails and must be removed or relocated. It is possible to remove them using the hammer or chisel but it is always better to lay out dust sheets prior to beginning any work.
After the access panel has been removed, you can start working on the sash. Use a flat bar or chisel to pull the small parting beads out of their grooves. They are usually wedged in or nailed but can be prised free which is why it's worth your time here. If the sash is still in place, break the mortise-and-tenon joints out with a screwdriver or hammer and then take out each wood peg. You should now be able to move the sash around without difficulty, though it may require oiling if it seems stiff.
With the sash open With the sash in an open position, measure the sash chain or cord to extend from the pulley at the top of the jamb to the sash slot at the bottom. Cut the cord or chain and attach it in Step 6 above. You can either employ a hammer and nail or screws, but nails are less likely to cause damage.
It is recommended to keep the weights that came with the original counterbalance unless you've purchased a kit that will replace the old counterbalance. They are not expensive and easy to install if purchased them from salvage shops for architectural use. Depending on the dimensions and shape of your window you might need to install one or two sashweights to keep the sash open.
