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 problems early, before they become too much.
The sash is the interior frame that is vertically moved upwards or downwards in windows that open. This article will show you how to make several easy repairs to your sash.
Weather Stripping
Wood window sashes add an elegant look to your home. If properly maintained, they will last for a long time. They may, however, become damaged or degraded with time due to exposure or normal wear and tear. Sash repair specialists can restore windows to their original state and maintain their appearance much longer than replacement windows.
The first step to sash window repair s is addressing weather stripping. It's found on both the sash and frame. If it's worn or loose, out, it can cause drafts, as well as other issues. Start by identifying the window's brand and the date of manufacture for the glass (etched on the glass's corner, or the aluminum spacers between panes). Take the sash off, and mark its width and height so that you can purchase new weather stripping that is compatible with the original.
Then, remove 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 have to remove the weights as well as their ropes that should have fallen into the pocket of the jamb liner. After removing the sash using the utility knife, take off the weather stripping from the old sash by hand or with the putty blade.
After the sash has been cleared, you can replace the parting stops. These are long pieces of wood that divide the two sashes. Pam prefers to use standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. However, you could also use a scrap piece of wood.
After removing the stopper and trimming it to length and then apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound with your putty tool, and allow it to dry for at least a day. After it has fully dried then apply a top coat of acrylic latex paint. This will protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that holds the window sashes can wear out with time and use. This can result in windows or doors that is difficult to open or close. The good thing is that fixing and replacing this hardware is usually relatively easy and affordable. If a sash is difficult to operate you can try spraying some lubrication into the jamb channel and then open it to see if that resolves the issue. If the issue continues, it is most likely to be due to the sash's balance. You'll need to remove the window sash to access the hardware.
Ideally, window sashes must move open and shut with very little effort, however, this can be a difficult task if the weights become worn or if the sash's meeting rail isn't properly glazed. This issue could be caused by various reasons such as an absence of maintenance or an unmatched weight rating.
If the hinge arms of a window are beginning to sag, this can cause the sash to drag and eventually strike the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To fix the problem make sure the sash is aligned in the frame's opening and remove it. If the sash is fixed to the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).
Because of sagging hinges and a general lack of energy efficiency, old windows particularly those in older homes, can be difficult to open or close. Many times, a few simple fixes can help these windows function smoothly once more and help homeowners save money on their energy bills.
It is essential to have the tools you need before you start. Mark the hinge channel's location on the frame (Photo 1) with a pencil. This will allow you to get the channel back into the correct position after you've finished. Then, remove the sash and take off the hardware, including the parting beads (Photo 2) and the cords or chains which hold it in place. Soften any hardened putty with the help of a heat gun set at medium and fitted with a shield for the nozzle. Remove the old sash, and store it in an bag that is labeled.
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 on sash can improve sash operation and reduce energy costs. Sash weights are heavy lead or iron cylinders, which are enclosed in a hidden cavity and connected to the movable sash by rope. They function as counterbalances, which allows you to open and close the window without having to use mechanical or electrical devices. When they fail, sashweights tend to be neglected or not used by homeowners.
It's not easy to retrieve 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 sash cord and some sash pulleys to tie the new sash weights to the sash cord.
Mortise and Tenon joints are used to join older wood windows. Pin punch and hammer can be used to take out the wood pegs holding the parts together. The majority of them have a large diameter on one side and a smaller size on the other side, so it is important to remove the small-diameter sides first. Later sashes used glue instead of pins. They can be cut by using a knife or a mallet.
After the sash has been removed and removed, you can take off the sash stop and gain access to the weight pocket. Usually it is done by drilling a hole near the bottom of each jamb. The hole is surrounded by an unfinished wooden panel that can be removed to reveal the inner workings.
After the sash has been stopped and the access panel removed, you will be able to take off the weight from the sash and replace it with new. Be sure to weigh the sash before you do this, as the old weights may be a different size than what you require. After the new weight has been installed, run an appropriate length of string through the pulling mechanism. Then, nail the string to your boxed frame. Leave a few inches protruding at the top of the string to allow for future adjustments.
Sash Cords
The majority of double-hung windows with a history come with a chain or cord 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 cable can restore the ability to raise and lower the sash and keep it in position when it is opened.
The first step to replace cords for sash is to locate and remove the access panels in the jambs. They are typically screwed or nailed in and must be removed. You could employ a hammer and chisel to prise them off however, it is always best to lay down dust sheets prior to starting any work.
After removing the access panel, you are able to begin to work on the sash. Use a flat bar or chisel to pry the small partsing beads out of their grooves. It is essential to take your time as they're often wedged or nailed in place. If the sash is still in place, break the mortise and tenon joints using a hammer and pin punch or screwdriver, then remove the wood pegs on each piece. You should be able to move the sash back and forth freely, although it may require oil if it feels stiff.
Take a measurement of the length of sash cord/chain needed to reach the sash slot on the bottom of the pulley on the top of the jamb. Cut the chain or cord and fix it using the step 6 above. You can either use a hammer and screws or nails, however nails are less likely to cause damage.
Unless you've bought a kit that replaces the old counterbalance system, it's recommended to keep the original balancing weights in place. It's not too expensive to purchase these from salvage shops for architectural purposes and they will be easy to install once you have the sash open. Depending on the size of your window two or three sash weights could be needed to keep it in an open position.
