Weather Stripping
Wood window sashes provide a classic aesthetic to your home and, when properly maintained, they can last for a long time. They may, however, get damaged or deteriorated over time, due to exposure and normal wear and tear. Sash repair experts can restore windows back to their original condition and keep them looking great much longer than replacement windows.
The first step for repair sash windows is to address weather stripping, which can be found on both the sash as well as the frame. If it's damaged or worn out, it could cause drafts and other problems. To fix it, begin by determining your window's brand and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its width and height, so you can find the appropriate weather stripping replacement to match.
Then, take the sash from its holder and place it on flat surfaces to allow you to reach all four sides. If the sash is double-hung, remove the ropes and weights that should fall into the pocket inside the jamb lining. After you have removed the sash using the utility knife, you can remove the weather stripping that was left by hand or with a putty knife.
Once the sash is clear it is time to replace the parting stops. These are long pieces wood that are used to separate the two sashes. Pam likes to replace them with standard 1/2-inch-by 3/4-inch window trim from the lumberyard. However, you can also use a piece of scrap wood.
After removing the parting stops and trimming them to your desired length, 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. After it has fully dried, apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a fresh appearance.
Sash Hardware
The hardware that supports window sashes prone to wearing out from age and use and the result could be a window or door that isn't able to open or close easily. It's a good idea to know that replacing and fixing this hardware is usually easy and affordable. If a sash is difficult to operate you can try spraying some grease into the jamb channel then slide it open to see if it solves the issue. If not, the issue is most likely due to the sash balance and you'll need to remove the sash in order to access the hardware.
The ideal situation is for window sashes to move open and shut with minimal effort but this can be an issue when the weights wear out or if the sash meeting rail isn't properly coated. This issue could be caused by a variety of reasons, such as lack of maintenance or by an incorrect weight rating for the specific window sash.
If the hinge arms of a window are beginning to lose their elasticity, this could cause the sash to slide and eventually land on the frame in the corner directly opposite the hinge arm (Photo 1). To fix this problem, first ensure that the sash fits squarely in the opening of the frame and then remove it from the window. If the sash is 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).
Windows that are old, especially in older homes, may be difficult to open and close because of sagging hinges and general inefficiency. Many times just a few easy fixes can allow these windows to operate smoothly once more and save homeowners money on energy bills.
To complete these repairs to sash it is important to have all the necessary tools lined up before you begin. Mark the hinge channel location on the frame (Photo 1) using a pencil. This will make it easier to put the channel in the proper location after you've completed. Remove the sash, and then remove the hardware including the parting beads (Photo 2) and the chains or cords which hold it in place. window repairs near me with nozzle shield and a medium setting can soften any putty that has been hardened. Remove the old sash and place it in a bag that is labeled.
Sash Weights
Sash weights can be changed to improve the operation of your window sash and decrease energy costs. Sash weights consist of iron or lead cylinders that are enclosed in a concealed cavity and are connected via ropes to the moveable window sash. These weights act as counterbalances, allowing you to open and shut the window without the need for mechanical or electrical devices. When they fail, sashweights tend to be left unnoticed or disabled by homeowners.
It's not easy to retrieve the sash-weight that fell from the cavity, so you'll want to find one that is suitable for the. You will also require a fresh piece of string, a length of sashcord and a few sashpulleys to secure the weights you are replacing to the cord.
Older windows made of wood are joined by mortise and tenon joints. 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 large on one side, and smaller on the other. It is essential to first remove the smaller diameter sides. Later sashes made use of glue instead of pins. They can be separated by using a knife or a mallet.
After the sash has been removed and removed, you can take off the stopper on the sash and get access to the weight pocket. This is usually done via tiny holes in the bottom of each jamb. This hole is covered by a wooden access panel that can be ripped off to allow you to see the inner workings of the frame.
After the sash has been stopped and the access panel removed, you'll be able to take off the old sash weight and replace it with the new. Make sure you weigh the sash before you do this, since the old weights may be different sizes than what you require. After the new weight is 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 the chain or cord is affixed to the weights. This supports and keeps the sashes within the jamb balanced. As time passes, these cords can get damaged and make it difficult to raise the windows. A new sash cord will give you the ability to move the sash upwards and downwards and hold it in place when opened.
The first step to replace cords for sash is to locate and remove the access panels in the jambs. They are usually nailed or screwed in and will need to be removed or repositioned. It is possible to remove them with a hammer or chisel, but it is always better to lay out dust sheets prior to beginning any work.
After you have removed the access panel, you are able to begin working on the sash. Utilize a flat bar or chisel, to pry the tiny parting beads from their grooves. They are typically wedged into or nailed, but they can be snipped out which is why it's worth your time. If the sash is still in place, break the mortise-and-tenon joints out using a hammer or screwdriver and then take out each wood peg. The sash should move freely, however it may require some lubrication in order to feel less stiff.
Measure the length of sash cord/chain needed to reach the sash slot on the bottom from the pulley on the top of the jamb. Cut the cord/chain and secure it in Step 6 above. You can use a hammer, nails, or screws. However, nails are less likely to cause damage.
Unless you've bought an upgrade kit to replace the counterbalance system that was in place before, it's best to keep the original balancing weights in place. It's cheap to purchase these from salvage shops for architectural purposes and they'll be easy to install once you have the sash open. Depending on the dimensions and shape of your window you might need to install one or two sashweights to keep the sash open.
