Weather Stripping
Wood window sashes give the classic look to your home. If properly maintained, can last for many years. They may, however, be damaged or degraded over time due to exposure and normal wear and tear. Sash repair experts can restore windows to their original condition and keep them looking great longer than replacement windows.
The first step to repair sash windows is to address weather stripping, which is found on both the sash as well as the frame. It can cause drafts if it's damaged or is 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). Remove the sash and mark its width and height so that you can find a replacement weather stripping that matches.
Next, remove the sash and place it on a work surface to allow access to all four sides. If your sash has a double-hung, you'll need to remove the weights as well as their accompanying ropes that should have fallen into the intended pocket in the jamb liner. Once you've taken the sash off using a utility knife, you can use it to cut away the weather stripping that was formerly in place at the corners. Then, remove it by hand or using a putty knife.
Once the sash has been cleared, you can install parting stops. These are long pieces that divide the sashes. Pam likes to replace these with standard 1/2-inch-by 3/4-inch window trim from the lumberyard, but you could also use scrap 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 with your putty knife, then let it dry for at least a day. After it has fully dried, apply a top coat of acrylic latex paint. This will help protect the putty and give your sash a modern look.
Sash Hardware
The hardware that supports window sashes may wear out over time and with use. This could 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 very simple and cost-effective. If you're having trouble opening a sash spray some lubricant into the jamb channel. Then, slide the sash open to see if that fixes the problem. If not, the issue is most likely due to the sash balance, and you'll need to take out the sash in order to access this hardware.
Window sashes need to open and close with little effort. However, this may be difficult if the weights are worn out or the sash-to rail connecting rail isn't covered with. This problem could be caused by a variety of factors that include an absence of maintenance or an unmatched weight rating.
If the hinge arms on windows begin to slide, this could cause the sash to drag and eventually hit against the frame at the opposite corner (Photo 1). To fix this problem, first ensure that the sash is squarely inserted into 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 need to loosen the hinge arm and replace it (Photo 2). Then, you can install the new sash (Photo 3).
Due to sagging hinges, and a general lack of energy efficiency, windows that are old, especially those in older homes, may be difficult to open and close. In many cases just a few easy fixes can allow these windows to operate smoothly again and help homeowners save money on energy bills.
In order to make these repairs to the sash it is important to have all of the necessary tools in place before you begin. Begin by marking the position of the hinge channel on the frame with pencil (Photo 1). This will make it easier to put the channel in the proper position after you've finished. Remove the sash and remove the hardware including the beads that separate (Photo 2) and the chains or cords that hold it in place. A hot gun with nozzle shield and medium setting will soften any hardened putty. Remove the old sash and keep it in a bag labeled.
Sash Weights
Whether your window sash repairs are to replace a damaged cord or simply to keep your windows functioning, replacing worn out sash weights will improve sash operation and cut down on the energy cost. Sash weights are made of heavy lead or iron cylinders that are encased in a concealed cavity and attached by ropes to the moveable window sash. These weights function as counterbalances, which allows you to open and shut the window without requiring mechanical or electrical devices. The sash-weights are typically disregarded or disabled by homeowners and turned into scrap when they fail. Consequently, you may need to locate replacements.
A sash weight that has fallen out of the cavity is difficult to retrieve It is therefore important to find a replacement that is suitable for the. You will also need an additional piece of string, a length of the sash cord, as well as some sash pulleys to connect the new sash weights onto the sash cord.
Older wood windows are joined using mortise and tenon joints. The wood pegs that hold the components together can be removed using a pin punch and hammer. The majority of these pegs are big on one side, but smaller on the other. It is important to remove first the smaller diameter sides. Sashes made later in the century made use of glue instead of pegs. They can be separated by cutting the glue line with a knife, then tapping the mortised part loose with a mallet.
Once the sash has been released, you can remove the sash stops and gain access to the pockets for weights. Usually this is accomplished by drilling an opening at the bottom of each jamb. This hole is covered with an unfinished wooden panel that can be removed to reveal the interior workings.
Once the sash is stopped and the access panel is removed, you are able to remove the old weight and replace it. Be sure to weigh the sash first, as the weights you have may not be the right size. After the new weight is installed, tie a string to it and thread it through the pulley for the sash. Then, attach the string to the boxed frame. Leave a few inches at the top of the string for future adjustments.
Sash Cords
Most old double-hung windows have a cord or chain attached to the weights which keeps the sashes in balance in the jamb. Over time, these cords may become damaged and make it difficult to raise windows. A new sash cable can 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 screwed or nailed into and must be removed. You could use a hammer or chisel to prise them off, but it's always better to lay down dust sheets prior to starting any work.
After you have removed the access panel, you are able to begin working on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves using the chisel or flat bar. It's important to be patient because they are usually stuck or nailed to the floor. If the sash is in place, break the mortise and tenon joints with pin punch and hammer or screwdriver, then remove the wood pegs on each piece. The sash should move around freely now, however it may need some lubrication to make it feel less stiff.
With the sash in an open position, measure enough sash cord/chain to extend from the pulley on the top of the jamb to the sash slot in the bottom. Cut please click the following web site or chain and attach it as described in the previous step. You can use a hammer and nail or screws, but nails are less likely to cause damage.
It is best to keep the weights that came with the original counterbalance unless you've purchased a kit that will replace the counterbalance. It's not expensive to buy these from salvage shops for architectural purposes and they will be easy to install once you've got the sash open. Depending on the dimensions and shape of your window you may need to use one or two sashweights in order to keep it open.
