Weather Stripping
Wooden window sashes are a great way to add an elegant look to your home. They are also durable and last for a long time if they are properly maintained. However, they can become damaged or degrade in time because of exposure to the elements and wear and tear. Sash repair specialists can restore windows to their original state and maintain their beauty longer than replacement windows.
The first step to repair sash windows is to address weather stripping. It's found on both the sash as well as the frame. If it's damaged or worn out, it can cause drafts and other problems. Begin by identifying the window's brand and the manufacturer's date (etched on the glass's corner or on the aluminum spacers between panes). Then, remove the sash and mark its height and width so that you can locate replacement weather stripping to match.
Then, take the sash from the holder and place it on an even surface that allows you to reach all four sides. If your sash has been double-hung, remove the weights with their ropes that should be buried inside the jamb lining. Once you've taken the sash off and the weights, use a utility knife to remove the old weather stripping at the corners. Then, remove it manually or using a putty knife.
When the sash is clean, you can replace the parting stops. These are long pieces of wood that separate the two sashes. Pam prefers to use standard 1/2-inch by 3/4-inch window trimming from the lumberyard. However, you can substitute for a scrap piece of lumber.
After removing the parting stop and cutting it to length after which, apply a thin layer of glazing compound on the bottom of the sash. Smooth it out using your putty knife, and then let it dry for at least a few days. Once it's fully cured then apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a new appearance.
Sash Hardware
The hardware that supports windows sashes can become worn out with time and use. This could lead to windows or doors that is difficult to open or close. It's good to know that replacing or repairing this hardware is often straightforward and cost-effective. If a sash isn't easy to operate try spraying lubrication into the jamb channel, and then slide it open to see if this fixes the problem. If the problem persists it's most likely the sash balance. It is necessary to take off the window sash in order to reach this hardware.
Window sashes need to be able to open and close with minimal effort. However, this may be a challenge if the weights have been worn out or the sash-to-rail connecting rail isn't properly glazed. 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 are starting to slide, this could cause the sash to slide and eventually land on the frame in the corner that's directly opposite the hinge arm (Photo 1). To remedy the issue make sure the sash is in the proper position within the frame opening, and then remove it. If the sash is screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).
Windows that are old, especially in older homes, may be difficult to open and close due to hinges that are sagging and general inefficiency. In most cases, a few simple repairs can transform these windows into smooth operators for the first time and save the homeowner money on energy bills.
It is essential to have the tools you need before you begin. Begin by marking the location of the hinge channel on the frame using a pencil (Photo 1). This will make it easier to put the channel in the correct location after you've completed. Take the sash off and take out all the hardware including the parting beads, cords, and chains that keep the sash in place. A hot gun with nozzle shield and a medium setting can soften any putty that has been hardened. Remove the old sash and store it in an bag with a label.
Sash Weights
No matter if your window sash repair needs are to replace a damaged cord or to keep the windows functional, replacing worn out weights for sash will improve its operation and help reduce energy costs. Sash weights consist of heavy lead or iron cylinders that are enclosed in a concealed cavity and are connected via ropes to the movable window sash. These weights function as counterbalances and allow you to open and close the window without the need for mechanical or electrical devices. When they fail, sashweights are often neglected or not used by homeowners.
It is difficult to recover an sash-weight which has fallen from the cavity, so you'll want to find one that is suitable for the. You will also need a new piece of string, a length sash cord, and a few sash pulleys that will tie the new sash weights the sash cord.
window repair and Tenon joints are used to join older wood windows. The wood pegs holding the parts together can be removed with the use of a pin punch and hammer. The majority of these pegs are big 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 utilized glue instead of pegs. They can be separated by cutting the glue line using the help of a knife, and then tapping the mortised section loose with mallets.
After the sash is released, you can remove sash stops and gain access to the pockets for weights. This is typically done by drilling tiny holes at the bottom of each jamb. The hole is then covered with a wooden access panel that can be ripped off to allow you to observe the inner workings of the frame.
When the sash has been shut off and the access panel has been removed, you can remove the weight you used and replace it. Be sure to weigh the sash before you do this, as the weights that were previously used may be different sizes than what is needed. After the new weight is installed you can tie a string around it and then thread it through the pulley for 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
Most double-hung windows of the past come with a chain or cord attached to the weights which helps keep the sashes level within the jamb. As time passes, these cords can get damaged and render it impossible to raise windows. A new sash cable will restore the ability to move and lower the sash, and ensure it stays in place when it is opened.
To replace sash cords the first step is to remove the access panels from the jambs. They are typically screwed or nailed into and require removal. It may be possible to remove them with an axe or hammer, but it is always better to lay out dust sheets before beginning any work.
After you have removed the access panel, you can begin working on the sash. Take the narrow beads (also called "tie rails") out of their grooves using flat bar or chisel. It is important to be patient as they're often placed in a wedge or nail. If the sash is still in place, break the mortise and tenon joints free with a hammer or screwdriver and then take out each wood peg. The sash should be able to move freely now, but it might require some lubrication in order to feel less stiff.
With the sash in an open position Take a measurement of the sash chain to extend from the pulley in the top of the jamb to the sash slot on the bottom. Cut the cord/chain and then fix it as described in the previous step. You can do this with a hammer, nails or screws. However, nails are less likely than screws to cause damage.
It is recommended to keep the original weights if you've purchased a kit to replace the counterbalance. They're not expensive and are easy to install if purchased them from salvage shops for architectural use. Depending on the dimensions and shape of your window you may require one or two sashweights in order to keep the sash open.
