Weather Stripping
Wood window sashes provide the classic look to your home. If properly maintained, they will last for many years. However, they can become damaged or degrade over time due to exposure to the elements and normal wear and tear. Sash repair specialists can restore windows back to their original condition and maintain their beauty longer than replacement windows.
Weather stripping is the most important thing to address when repairing windows with sash. It's located on both the frame and sash. If like this damaged or worn out, it could 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 corners or on the aluminum spacers between panes). Remove the sash, and mark its size and width so that you can get new weather stripping that is compatible with the original.
Next, remove the sash and place it on a table to allow access to all four sides. If your sash is double-hung, you'll have to remove the weights and the ropes that go with them, which should have fallen into the intended pocket in the jamb liner. After you have removed the sash using the utility knife, take off the weather stripping that was left by hand or with a putty blade.
After the sash is cleared, you can replace the stoppers that separate the two sashes. These are long pieces 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, but you can also use scrap wood.
After removing the stopper for the parting and cutting it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth it out using your putty knife and let it dry for a minimum of a day. When the putty is fully cured and dried, you can apply a topcoat of acrylic. This will protect the putty, and give your sash an updated appearance.
Sash Hardware
The hardware that supports windows sashes can become worn out with time and use. This can 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 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 this resolves the issue. If the issue continues it's likely that the sash balance is off. You'll need to take off the window sash in order to access the hardware.
Ideally, window sashes must swing open and closed with minimal effort but this is an issue if the weights become worn or if the sash's meeting rail isn't properly glazed. This problem could be caused by a variety of factors that include 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 to slide and eventually strike the frame in the corner opposite the hinge arm (Photo 1). To fix this issue, first make sure the sash is firmly seated in the opening of the frame and then remove it from the window. If the sash has been screwed to the hinge arm, you'll have to remove the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).
Due to hinges that are sagging, and a general deficiency in energy efficiency, older windows, especially those in older houses, could be difficult to open and close. In many instances, a few minor repairs can turn these windows into smooth operators again and save the homeowner money on energy bills.
To complete these repairs to sash, it's important to have all of the tools needed before you begin. Begin by marking the position of the hinge channel on the frame with pencil (Photo 1). This will help you to place the channel in the right position after you've finished. Remove the sash, and remove all the hardware, including the parting beads cords, chains, and cords that hold the sash in place. A hot gun with nozzle shield and medium setting will soften any hardened glue. Take off the old sash and store it in a bag with a label.
Sash Weights
If your window sash repairs are to replace a broken cord or to keep your windows functioning, replacing worn out weights on sash can improve sash operation and cut down on the energy cost. Sash weights are hefty lead or iron cylinders enclosed in a concealed cavity and attached to the movable sash by a rope. These weights function as counterbalances, which allows you to open and close the window without the need for mechanical or electrical devices. The sash weights are usually neglected or ignored by homeowners, and are turned into scrap when they fail; therefore you may have to locate replacements.
It's difficult to retrieve an sash-weight which has fallen from the cavity, so you'll need to find one that is suitable for the. You will also require a new piece of string, a length sash cord, and a few sash pulleys that will tie the new sash weights 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 these pegs are large on one side and smaller on the other. It is essential to first remove the smaller diameter sides. Sashes made later in the century utilized glue instead of pegs. They can be separated by cutting the glue line with the help of a knife, and then tapping the mortised part loose using a mallet.
After the sash is removed, you can take off the stops on the sash and get access to the weight pockets. Usually, this is done through an opening at the bottom of each jamb. This hole is covered with an unfinished wooden panel that can be removed to reveal the inside workings.
After you have the sash stopped and the access panel removed, you will be able to take off the weight of the old sash and replace it with the new. Make sure you weigh the sash prior to you begin, as the weights that were previously used may be different sizes than what you require. After the new weight has been installed, you can thread an appropriate length of string through the pulling mechanism. Then nail the string to the boxed frame, leaving a few inches of string sticking out from the head for future adjustment.
Sash Cords
The majority of double-hung windows with a history come with a chain or cord attached to the weights that supports and keeps the sashes level in the jamb. As time passes, these cords may break, making it difficult to raise the window. A new sash cable can restore the ability to move and lower the sash, and ensure it stays in place when opened.
The first step in replacing cords for sash is to locate and remove the access panels within the jambs. These are usually nailed or screwed in and must be removed or relocated. It may be possible to take them out using an axe or hammer, but it is always better to lay out dust sheets prior to starting any work.
After removing the access panel, you are able to begin to work on the sash. Make the small parting beads (also known as "tie rails") out of their grooves with flat bar or chisel. They are typically wedged into or nailed but can be removed and it's worth your time here. If the sash is still in place, break the mortise and tenon joints with a hammer and pin punch or screwdriver, then remove the wood pegs attached to the components. The sash should be able move around freely now, however it may need some lubrication in order to feel less stiff.
With the sash in an open position Take a measurement of the sash chain to reach from the pulley on the top of the jamb to the sash slot on the bottom. Cut the cord/chain and then fix it using Step 6 above. You can use either a hammer, nails, or screws. However, nails are less likely than screws to cause damage.
Unless you've bought an item that replaces the old counterbalance system, it is recommended to keep the original weights for balancing in place. It's not too expensive to purchase these from salvage shops for architectural purposes and they'll be simple to install once you've got the sash open. Based on the size and shape of your window you might need to install one or two sashweights in order to keep it open.
