Window Sash Repairs
Window sashes need to be checked regularly for mold, mildew and other damage. By catching problems before they become serious you can save money on repairs in the future.
The sash 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 make several simple sash repairs.
Weather Stripping
Wood window sashes give a classic aesthetic to your home and, when properly maintained, can last for many years. However, they can get damaged or deteriorated over time due to exposure and normal wear. Thankfully, sash repair experts can bring your windows back to their original condition and keep them looking fantastic for much longer than newer replacement windows.
The first step in repair sash window damage is to fix weather stripping, which can be found on both the sash and frame. If it's damaged or worn out, it could cause drafts and other problems. Begin by identifying the brand of window and the glass manufacturer's date (etched on the corner of the glass, or the aluminum spacers between panes). Then, remove the sash and mark its height and width, so you can find new weather stripping that matches.
Then, you can remove the sash from the holder and place it on an even surface that allows you to see all four sides. If your sash was double-hung, remove the ropes and weights that should fall into the pocket inside the jamb lining. Once you've taken the sash off, use a utility knife to cut off the weather stripping that was formerly in place at the corners, and then remove it manually or using a putty blade.
After window glass repair near me has been cleaned, you can replace parting stops. These are long pieces wood that are used to separate the two sashes. Pam prefers to use the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. But, you can also use for a scrap piece of lumber.
After removing the parting stop and cutting it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound with your putty knife and let it dry for a minimum of a day. When it's completely dried then apply a top coat of acrylic latex paint. This will help protect the putty, and give your sash an updated look.
Sash Hardware
The hardware that holds the window sashes may wear out with time and 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 generally relatively easy and affordable. If you're having trouble opening a sash, spray some oil into the jamb channel. Then slide the sash open to see if that fixes the issue. If the problem persists it's most likely to be due to the sash's balance. You will need to remove the window sash in order to access the hardware.
Sashes for windows should be able to open and close with little effort. However, this can be a challenge if the weights have been worn out or the sash connecting rail isn't properly glazed. This problem could be caused by various reasons that include a lack of maintenance and an unmatched weight rating.
If the hinge arms of a window begin to sag, this can cause the sash to drag and eventually land on the frame in the corner that's directly opposite the hinge arm (Photo 1). To resolve this problem, first ensure that the sash fits squarely in the opening of the frame and then remove it from the window. If the sash has been screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).
Due to hinges that are sagging, and a general lack in energy efficiency, older windows particularly those in older homes, can be difficult to open or close. In many cases, a few simple repairs can transform these windows into smooth operators and save homeowners money on energy bills.
It is crucial to have the tools you need before you start. Mark the hinge channel location on the frame (Photo 1) using a pencil. This will allow you to position the channel in the proper position after you've finished. Remove the sash and then remove all hardware including the parting beads cords, chains, and cords that help to hold the sash. A hot gun with nozzle shield and a medium setting will soften any hardened putty. Remove the old sash, and keep it in a labeled bag.
Sash Weights
Sash weights can be replaced to improve the operation of your window sash and decrease the energy cost. Sash weights are hefty lead or iron cylinders that are enclosed in a hidden cavity and linked to the moveable window sash using rope. These weights act as counterbalances and allow you to open and shut the window without having to use mechanical or electrical devices. The sash-weights are typically neglected or ignored by homeowners and turned into scrap when they fail. Consequently you might need to search for replacements.
It's not easy to retrieve a sash-weight that has fallen from the cavity, so you'll need to find one that is suitable for the. You will also require a new piece string, a length of sashcord and some sashpulleys to tie the new weights to the cord.
Mortise and Tenon joints are used to join windows made of older wood. The wood pegs that hold the components together can be removed by pin punches and hammers. The majority of them have large diameters on one side and a smaller size on the other side, so it is important to remove the small-diameter sides first. Later sashes made use of glue instead of pins. They can be cut by using a knife and mallet.
After the sash is released, you can remove the sash stops and gain access to the weight pockets. This is usually done via a small hole in the bottom of each jamb. This hole is then covered by an access panel made of wood which can be removed to allow you to view the inside of the frame.
After you have the sash stopped and the access panel removed, you will be able to remove the weight of the old sash and replace it with new. Make sure you weigh the sash before you do this, since the old weights may be a different size than what is needed. Once the new weight has been installed, thread a string through the sash pulling mechanism. Then attach the string to the boxed frame, leaving a few inches of string protruding from the head 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 which keeps the sashes in balance in the jamb. As time passes, these cords may break, making it impossible to raise the window. A new sash cable can restore the ability to move and lower the sash and keep it in place when opened.
The first step in replacing sash cords is to find and take out the access panels located in the jambs. These are usually screwed or nailed in and need to be removed. It may be possible to remove them using a hammer or chisel, but it is always better to lay out dust sheets before beginning any work.
Once the access panel is removed, you can start working on the sash. Take the narrow beads (also called "tie rails") out of their grooves with a chisel or flat bar. It is essential to be patient because they are usually stuck or nailed to the floor. If the sash is still in place, pry out the mortise and the tenon joints by using a hammer and pin punch or screwdriver, then unhook the wood pegs that are on the components. The sash should move freely, however it might require some lubrication to make it feel less stiff.
With the sash in an open position With the sash in an open position, measure the sash chain or cord to extend from the pulley in the top of the jamb to the sash slot in the bottom. Cut the cord or chain and attach it in the previous step. You can use a hammer and screws or nails, however nails are less likely to cause damage.
If you haven't purchased a kit that replaces the old counterbalance system, it's best to keep the original weights for balancing in place. They're not costly and are easy to install if you buy them at architectural salvage stores. Depending on the size and shape of your window you might need to install one or two sashweights to keep it open.
