Weather Stripping
Wood window sashes add an elegant look to your home. When properly maintained, they can last for a long time. However, they may become damaged or degrade in time due to exposure to elements and normal wear and tear. However, sash repair experts can restore your windows back to their original condition and keep them looking fantastic for a longer period of time than replacement windows.
Weather stripping is the most important thing to address when repairing windows with sash. It is located on both the frame and sash. If it's loose or worn out, it can lead to drafts and other problems. Start 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). Take the sash off, and mark its width and height so that you can get replacement weather stripping that matches.
Then, remove the sash and place it on a surface so that you can reach all four sides. If your sash has a double-hung, you'll need to take off the weights and the ropes that go with them that should have fallen into the pocket of the jamb liner. After you have removed the sash using the utility knife, you can remove the weather stripping that was left by hand or using the putty blade.
After the sash has been cleared, you can replace the 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 could also use scrap wood.
After removing the parting stops and cutting them to the desired length and thickness, apply a thin layer of glazing compound over the bottom of the sash. Smooth out the compound using your putty knife and let it dry for at least a day. Once it's fully cured then apply a top coat of acrylic latex paint. This will protect the putty, and give your sash a modern look.
Sash Hardware
The hardware that holds the window sashes may wear out over time and with use. This could result in a door or a window that is difficult to open or close. The good news is that repairing and replacing this hardware is typically quite simple and inexpensive. If you're having trouble opening a sash spray some grease into the jamb channel. Then slide the sash out to see if this resolves the issue. If the issue persists it's most likely that the sash balance is off. You will need remove the window sash in order to reach this hardware.
Window sashes should open and close without much effort. However, this may be a challenge if the weights have been worn out or the sash-to-rail connecting rail isn't covered with. This issue can be due to many factors such as a lack of maintenance and an unmatched weight rating.
If the hinge arms of a window are starting to lose their elasticity, this could cause the sash to slide 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 that the sash is in the proper position within the frame's opening and remove it. If the sash has been screwed to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).
Due to sagging hinges, and a general deficiency in energy efficiency, older windows particularly those in older homes, may be difficult to open or close. In most instances, a few minor repairs can transform these windows into smooth operation and save homeowners cash on energy costs.
To make these repairs to sash it is important to have all of the tools needed before you begin. Mark the location of the hinge channel on the frame (Photo 1) using a pencil. This will allow you to put the channel in the correct position after you've finished. Take the sash off, and remove all the hardware including the parting beads cords, chains, and cords that keep the sash in place. Heat gun with nozzle shield and a medium setting can soften any hardened putty. Remove the old sash, and keep it in a bag with a label.
Sash Weights
Sash weights are able to be replaced to enhance the efficiency of your window sash and decrease energy costs. Sash weights are heavy, lead or iron cylinders, which are enclosed in a hidden cavity and linked to the moveable sash by a rope. These weights act as counterbalances and allow you to open and shut the window without having to use mechanical or electrical devices. When they fail, sashweights tend to be ignored or disabled by homeowners.
It is difficult to recover the sash-weight that fell from the cavity, so you'll want to find one that fits correctly. You will also require a fresh piece of string, a length of sashcord and some sashpulleys to tie the new weights to the cord.
Older wood windows are joined with mortise and tenon joints. The wood pegs that hold the parts together can be removed using pin punches and hammers. The majority of these pegs are large on one side and smaller on the other. It is essential to remove first the smaller diameter sides. Sashes that were made later in the century made use of glue instead of pegs. They can be separated by cutting through the glue line with a knife, then tapping the mortised part loose using a mallet.
Once the sash is freed and removed, you can take off the stopper on the sash and get access to the weight pocket. This is usually done via a small hole at the bottom of each jamb. This hole is covered with an unfinished wooden panel that can be removed to reveal the interior workings.
When the sash has been shut off and the access panel is removed, you can remove the weight you used and replace it. Be sure to weigh the sash before you do this, as the old weights may be different sizes than the one you need. After the new weight has been installed, run an appropriate length of string through the pulling mechanism. Then, nail the string to the boxed frame. Leave a few inches of space at the end of the string to allow for future adjustments.
Sash Cords
The majority of double-hung windows with a history have a cord or chain connected to the weights that keeps the sashes in balance within the jamb. Over time, these cords can become damaged and make it impossible to raise windows. A new sash cord will give you the ability to move the sash upwards and downwards and hold it in position when it is opened.
To replace sash cords, the first step is to remove the access panels from the jambs. They are typically attached by nails or screws and need to be removed. It may be possible to remove them with the hammer or chisel however, it is best to lay out dust sheets prior to starting any work.
After you have removed the access panel, you can begin working on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves with the chisel or flat bar. It is important to take your time because they are usually placed in a wedge or nail. If the sash is still in place, pry out the mortise and tenon joints with a hammer and pin punch or screwdriver, and then take out the wood pegs that are on each piece. It should now be possible to move the sash around freely, though it might require oiling if it seems stiff.
With the sash open Take a measurement of the sash chain to extend from the pulley at the top of the jamb to the sash slot in the bottom. Cut the cord/chain and then fix it as described in the previous step. You can employ a hammer, screws or nails, however nails are less likely to cause damage.
If you don't have a kit that replaces the counterbalance system that was in place before, it's recommended to keep the original balancing weights in place. They are not expensive and easy to install if you purchase them from salvage shops for architectural use. Based on the size of your window two or three sash weights could be needed to keep it open.
