Window Sash Repairs
Sashes for windows must be inspected regularly for signs of mold, mildew and damage. If you catch these issues early, you can save money on repairs in the future.
The sash is the internal frame that is vertically moved upwards or downwards in windows that are open. This article will teach you how to make several simple sash repairs.
Weather Stripping
Wooden window sashes can give a classic look to your home. They are also sturdy and will last for many years provided they are properly maintained. They may, however, be damaged or degraded over time due to exposure or normal wear and tear. Fortunately, sash repair specialists can restore your windows back to their original condition and keep them looking great for much longer than newer replacement windows.
Weather stripping is the primary thing to address when repairing windows with sash. It's located on both the frame and sash. It could cause drafts if worn out or loose. To fix it, begin 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). Take the sash off, and mark its width and height so you can find a new weather stripping that is compatible with the original.
Then, you can remove the sash from the holder and place it on a flat surface to allow you to see all four sides. If the sash is double-hung, you'll also need to remove the weights as well as their ropes that should have fallen into the intended pocket in the jamb liner. Once you've removed the sash and the weights, use a utility knife to cut off the weather stripping that was formerly in place at the corners. Then, remove it manually or using a putty knife.
Once the sash has been cleared, you can install the stoppers that separate the two sashes. These are long pieces wood that are used to separate the two 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 stopper for the parting and trimming it to length after which, apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound using a putty tool, and allow it to dry for at least a day. When the putty is fully cure, you can apply an acrylic latex topcoat. This will help protect the putty, and give your sash a fresh appearance.
Sash Hardware
The hardware that supports the window sashes may wear out over time and use. This can result in a door or a window that is difficult to open or close. The good thing is that fixing and replacing this hardware is generally quite simple and inexpensive. If you are having trouble opening a sash spray some grease into the jamb channel. Then slide the sash out to see if this resolves the problem. If the issue continues, it is most likely that the sash balance is off. You'll need to take off the window sash in order to reach this hardware.
Ideally, window sashes must swing open and closed without effort, but this can be difficult when the weights are worn or if the sash meeting rail isn't properly coated. This problem could be caused by a variety of factors that include a lack of maintenance and a mismatched weight rating.
If the hinge arms of a window are beginning to sag, this can cause the sash to slide and eventually hit the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To fix the problem ensure that the sash is in the proper position within the frame's opening and take it off. If the sash has been fixed to the hinge arm, remove the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).
Due to sagging hinges, and a general lack in energy efficiency, windows that are old, especially those in older homes, may be difficult to open or close. Many times, a few simple fixes can make these windows operate smoothly again and save homeowners money on their energy bills.
To complete these repairs to the sash, it's important to have all of the tools needed before you begin. Begin by marking the location of the hinge channel on the frame using pencil (Photo 1). This will assist you in getting the channel back on position correctly after you've completed. Then, remove double glazing Sidcup and remove the hardware including the beads that separate (Photo 2) and the cords or chains that secure it. Soften any hardened putty with an electric heat gun set to medium and fitted with an nozzle shield. Take off the old sash and keep it in a labeled bag.
Sash Weights
Sash weights are able to be replaced to enhance the efficiency of your window sash and reduce the cost of energy. Sash weights are heavy, lead or iron cylinders that are enclosed in a hidden cavity and attached to the movable sash by a rope. They function as counterbalances and allow you to open and close the window without the need for mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners, and are turned into scrap when they fail. Consequently you may have to search for replacements.
It is difficult to recover the sash-weight that fell from the cavity, so you'll want to find one that is suitable for the. You will also require an additional piece of string, a length of sash cord, and a few sash pulleys that will tie the new sash weights onto the sash cord.
Older wood windows are joined by mortise and tenon joints. The wood pegs that keep the components together can be removed by 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 important to first remove the smaller diameter sides. Later sashes used glue instead of pins. They can be cut by using a knife or mallet.
After the sash has been removed then you can take out the sash stop and access the weight pocket. This is usually done via tiny holes at the bottom of each jamb. The hole is then covered with the wooden panel which can be removed to reveal the inner workings.
After the sash has been stopped and the access panel has been removed, you can remove the weight you used and replace it. Be sure to weigh the sash prior to you do this, since the weights that were previously used may be a different size than what is needed. After the new weight is installed, thread a string through the sash pulling mechanism. Then, you can attach the string to your boxed frame. Leave a few inches protruding at the top of the string for future adjustments.
Sash Cords
The majority of double-hung windows with a history come with a chain or cord attached to the weights which supports and keeps the sashes in balance in the jamb. Over time, these cords may become damaged and render it impossible to raise windows. A new sash cord will give you the ability to move the sash upwards and downwards and will keep it in its position when it is opened.
To replace sash cords, the first step is to remove the access panels from the jambs. They are typically installed by screws or nails and will require to be removed or repositioned. You may be able to employ a hammer and chisel to remove them however, it is always best to lay down dust sheets prior to beginning any work.
After removing the access panel, you can begin to work on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves using the chisel or flat bar. They are usually wedged in or nailed, but they can be removed which is why it's worth your time. If the sash is still in place, remove the mortise and tenon joints with pin punch and hammer or screwdriver, then unhook the wood pegs attached to the components. The sash should be able move around freely now, however it may need some lubrication to feel less stiff.
Measure the length of sash cord/chain needed to reach the sash slot at the bottom of the pulley located at the top of the jamb. Cut the cord or chain and secure it as in Step 6 above. You can do this with a hammer, nails or screws. However, nails are less likely than screws to cause damage.
It is best to keep the original weights if you've purchased a kit that will replace the counterbalance that was previously installed. They're not costly and simple to install if purchased them from salvage shops for architectural use. Depending on the size of your window one or two sashweights might be required to keep the sash in an open position.
