Weather Stripping
Wood window sashes give an elegant look to your home and, when properly maintained, can last for many years. However, they can become damaged or degrade as time passes because of exposure to the elements and wear and wear and tear. However, sash repair experts can restore your windows back to their original condition and keep them looking fantastic for longer than replacement windows.
The first step for sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. It can cause drafts if worn out or loose. To fix it, start by determining the brand of your window and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its height and width to find new weather stripping that matches.
Then, you can remove the sash from its holder and place it on an even surface that allows you to reach all four sides. If the sash is double-hung, take out the ropes and weights that should have fallen into the pocket in the jamb lining. Once you've taken the sash off and the weights, use a utility knife to cut away the old weather stripping at the corners, and then remove it manually or with a putty knife.
Once the sash is clear, you can replace the parting stops. These are long pieces that separate the sashes. Pam prefers to use the standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. However, you could also substitute a scrap piece of wood.
After removing the stoppers for parting and cutting them to the desired length then apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound using a putty tool and let it dry for at least a day. When it's completely dried, apply a top coat of acrylic latex paint. This will protect the putty and give your sash a new look.
Sash Hardware
The hardware that supports window sashes susceptible to wear and tear from age and use and the result could be a door or window that can't be opened or closed easily. It's good to know that replacing and fixing this hardware is usually straightforward and cost-effective. If a sash becomes difficult to operate try spraying oil into the jamb channel then slide it open to see if this fixes the problem. If the issue persists it's most likely the sash balance. You will need remove the window sash to access the hardware.
Ideally, window sashes must be able to open and close with minimal effort however, this can be difficult when the weights are worn or if the sash meeting rail isn't properly glazed. This problem can be caused by a number of factors, including the lack of maintenance or a mismatched weight rating for the specific sash.
If the hinge arms of a window begin to sag, this can cause the sash's to drag and eventually strike the frame in the corner opposite the hinge arm (Photo 1). To correct the issue ensure that the sash is centered in the frame opening and then remove it. If the sash has been screwed onto the hinge arm, remove the hinge and replace it. (Photo 2). Install the new sash (Photo 3).
Old windows, especially those in older houses, can be difficult to open and close because of sagging hinges and a general inefficiency. In many cases, a few simple repairs can turn these windows into smooth operation for the first time and save the homeowner money on energy bills.
It is crucial to have the tools needed before you start. Begin by marking the position of the hinge channel on the frame using a pencil (Photo 1). This will help you to position the channel in the correct position after you've finished. Remove the sash and take out all the hardware including the parting beads cords, chains, and cords that hold the sash in place. Soften any putty that has been hardened with a heat gun set to medium and fitted with an nozzle shield. Take off the old sash and store it in an bag that is labeled.
Sash Weights
If your window sash repairs are to replace a broken cord or simply to keep your windows functioning by replacing worn out weights on sash can improve sash operation and reduce the energy cost. Sash weights are composed of heavy lead or iron cylinders that are enclosed in a concealed cavity and attached by ropes to the movable window sash. These weights function as counterbalances and allow you to open and shut the window without the need for mechanical or electrical devices. The sash weights are often ignored or discarded by homeowners and turned into scrap when they fail; therefore, you may 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 fits correctly. You will also require a fresh piece of string, a length of sashcord and a few sashpulleys for tying the weights you are replacing to the cord.
Older wood windows are joined using mortise and tenon joints. The wood pegs that keep the parts together can be removed by pin punches and hammers. The majority of them are large on one side, and smaller on the other. It is crucial to remove first the smaller diameter sides. Later sashes used glue instead of pins. They can be separated by using a knife or a mallet.
Once the sash is freed then you can take out the sash stop and gain access to the weight pocket. Usually, this is done through a hole near the bottom of each jamb. This hole is then covered by an access panel made of wood that can be ripped off so that you can view the inside of the frame.
After the sash has been stopped and the access panel has been removed, you can take off the old weight and replace it. Be sure to weigh the sash before you begin, as the old weights may be different sizes than the one you need. Once the new weight has been installed, run the string through the sash pulling mechanism. Then, you can attach the string to the boxed frame. Leave a few inches of space at the head of the string for future adjustments.
Sash Cords
Most double-hung windows of the past include a chain or cord connected to the weights that supports and keeps the sashes balanced within the jamb. Over time, these chains may become damaged and make it difficult to raise the windows. A new sash cord will restore the ability to move the sash up and down and will keep it in its place when it is opened.
The first step in replacing cords for sash is to locate and remove the access panels within the jambs. They are typically screwed or nailed in and must be removed. It may be possible to remove them using an axe or hammer, but it is always best to lay out dust sheets before beginning any work.
After you have removed the access panel, you can begin to work on the sash. Utilize a flat bar, or chisel, to pry the narrow parting beads out of their grooves. It's important to take your time as they're often stuck or nailed to the floor. If the sash remains 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 each piece. The sash should be able to move freely now, but it might require some lubrication to feel less stiff.
Determine the length of sash chain/sash cord required to reach the sash slot at the bottom, and the pulley at the top of the jamb. Cut the cord or chain and attach it in Step 6 above. You can use either a hammer, nails, or screws. However, nails are less likely to cause damage.
If window repair near me don't have an item that replaces the counterbalance system that was in place before, it is recommended to keep the original balancing weights in place. It's cheap to purchase them from architectural salvage stores and they'll be simple to install once you've got the sash unlocked. Depending on the dimensions and shape of your window, you may require one or two sashweights in order to keep it open.
