Weather Stripping
Wood window sashes provide a classic aesthetic to your home. When properly maintained, they can last for a long time. They may, however, be damaged or degraded over time, due to exposure and normal wear. Fortunately, sash repair specialists can restore your windows back to their original condition and maintain their appearance for longer than replacement windows.
The first step to repair sash windows is to address weather stripping, which can be found on both the sash and frame. It could cause drafts if worn or loose. Start by identifying the window's brand and the date of manufacture for the glass (etched on the corner of the glass or the aluminum spacers between panes). Then, remove the sash and mark its height and width to find replacement weather stripping to match.
Then, remove the sash and set it on a surface to allow access to all four sides. If your sash has been double-hung, remove the weights with their ropes that should fall into the pocket inside the jamb lining. After you've removed the sash using a utility knife, you can use it to cut away the old weather stripping at the corners, and then take it off by hand or with a putty knife.
After the sash has been cleared, you can replace the parting stops. These are long pieces that separate the sashes. Pam likes to replace these with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard, however you can also replace them with a piece of scrap wood.
After removing the parting stops and trimming them to your desired length, apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using a putty tool and let it dry at least one day. When the putty is fully cure and dried, you can apply a topcoat of acrylic. This will help protect the putty and give your sash a modern look.
Sash Hardware
The hardware that holds the window sashes can wear out over time and use. This could lead to the window or door that is difficult to open or close. It's good to know that replacing or fixing this hardware is usually straightforward and cost-effective. If you are having trouble opening a sash, spray some lubricant into the jamb channel. Then, slide the sash up and open to see if that fixes the problem. If not, upvc window repairs is most likely due to the sash balance and you'll need to remove the sash to access the hardware.
Window sashes need to be able to open and close with minimal effort. However, this could be a challenge if the weights have been worn out or the sash-to-rail connecting rail isn't properly glazed. This could be caused by a variety of factors that include a lack of maintenance and an unmatched weight rating.
If the hinges on windows begin to slide, this can cause the sash drag and then hit the frame in the opposite corner (Photo 1). To fix this issue, first make sure the sash is firmly seated in the opening of the frame and then take it out of the window. If the sash has been screwed to the hinge arm, you'll have to loosen the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).
Windows that are old, especially in older homes, can be difficult to open and close because of sagging hinges and a general inefficiency. In most instances, a few easy repairs can turn these windows into smooth operation again and save the homeowner cash on energy costs.
It is crucial to have the tools you need before you begin. Begin by marking the location of the hinge channel on the frame using pencil (Photo 1). This will allow you to get the channel back in the correct position after you've finished. Then, remove the sash, and then remove the hardware including the parting beads (Photo 2) and the chains or cords that hold it in place. A hot gun with nozzle shield and a medium setting can soften any putty that has been hardened. Take off the old sash and store it in a labeled bag.
Sash Weights
No matter if your window sash repair needs are to replace a damaged cord or just to ensure that the windows are functional and functional, replacing worn-out weights for sash will improve its operation and reduce energy consumption. Sash weights are made of heavy lead or iron cylindricals that are contained in a hidden cavity and are connected via ropes to the movable window sash. They provide counterbalance which allows the window to be shut and opened without the use of electrical or mechanical devices. The sash weights are often disregarded or disabled by homeowners, and are turned into scrap when they break; therefore, you may need to search for replacements.
A weight in a sash that has fallen out of the cavity is difficult to get back and you'll need to locate a new one that fits correctly. You will also require a new piece of string, a length of sashcord and some sashpulleys to tie the new weights to the cord.
Older wood windows are joined by mortise and tenon joints. The wood pegs holding the components together can be removed using a pin punch and hammer. Most of these pegs have a large diameter on one side and a smaller size on the other side, so it is crucial to take out the smaller-diameter sides first. Sashes that were made later in the century made use of glue instead of pegs and can be separated by cutting through the glue line using an instrument, and then tapping the mortised part loose with mallets.
Once the sash is freed and removed, you can take off the sash stop and access the weight pocket. Usually, this is done through an opening in the bottom of each jamb. This hole is then covered by an access panel of wood that can be cut off to let you observe the inner workings of the frame.
After you have the sash stopped and the access panel removed, you will be able to take off the weight from the sash and replace it with new. First, weigh the sash to ensure that the weights you have might not be of the right size. After the new weight has been installed, you can thread the string through the sash pulling mechanism. Then, you can nail the string to the boxed frame, leaving a few inches of string sticking out from the head to allow for future adjustments.
Sash Cords
In the majority of old double-hung windows, a chain or cord is attached to the weights. This keeps the sashes in the jamb in a balanced manner. Over time, these cords could break, making it impossible to raise the window. A new sash cable will restore the ability to move and lower the sash and keep it in place when it is opened.
To replace sash cords, the first step is to remove the access panels from the jambs. They are usually attached by nails or screws and must be removed. You may be able to employ a hammer and chisel to remove them however, it is always best to lay down dust sheets before starting any work.
After you have removed the access panel, you can begin to work on the sash. Take the narrow beads (also known as "tie rails") out of their grooves with a chisel or flat bar. It's important to take your time, as these are often wedged or nailed in place. If the sash is still in place, pry out the mortise and tenon joints with the help of a hammer and pin or screwdriver, then remove the wood pegs attached to each component. The sash should move freely, however it may need some lubrication in order to feel less stiff.
With the sash open, measure enough sash cord/chain to extend from the pulley at the top of the jamb to the sash slot in the bottom. Cut the cord/chain and fix it using Step 6 above. You can either use a hammer and screws or nails, however nails are less likely to cause damage.
It is recommended to keep the weights that came with the original counterbalance unless you've purchased a kit to replace the counterbalance that was previously installed. It's not too expensive to purchase them from a salvage store and they will be easy to install once you have the sash opened. Depending on the dimensions and shape of your window, you may require one or two sashweights in order to keep it open.
