Weather Stripping
Wood window sashes add an elegant look to your home and, when properly maintained, they will last for many years. They can, however, get damaged or deteriorated over time, due to exposure and normal wear.

Weather stripping is the most important thing to address when repairing sash windows. It's located on both the frame and the sash. If it's damaged or worn out, it could cause drafts, as well as other issues. Begin by identifying the window brand and the manufacturer's date (etched on the glass's corners, or the aluminum spacers between panes). Take the sash off, and mark its width and height so that you can purchase replacement weather stripping that matches.
Then, remove the sash and set it on a work surface to allow access to all four sides. If your sash is double-hung, you'll also need to remove the weights and their ropes, which should have fallen into the pocket that was intended to be in the jamb liner. Once you've taken the sash off using a utility knife, you can use it to cut off the old weather stripping at the corners, then take it off by hand or with a putty knife.
After the sash has been cleaned, you can replace the stoppers that separate the two sashes. These are long pieces that divide the sashes. Pam likes to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard, but you can also replace them with a piece of scrap wood.
After removing the stopper for the parting and cutting it to length, apply a thin coat of glazing compound over the bottom of the sash. Smooth out the compound using your putty knife, then let it dry for at least a few days. Once it's fully cured, apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a fresh look.
Sash Hardware

Ideally, window sashes must swing open and closed with very little effort, however, this can be an issue if the weights become worn or if the sash that joins rail isn't properly double glazed window repairs near me. This issue can be due to many factors such as an absence of maintenance or an unmatched weight rating.
If the hinge arms on the window begin to move, this could cause the sash to drag and then hit the frame in the opposite corner (Photo 1). To address this problem, first ensure that the sash fits squarely 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 need to loosen the hinge arm and replace it (Photo 2). Then, you can install the new sash (Photo 3).
Old windows, especially those in older houses, can be difficult to close and open due to sagging hinges and general inefficiency. Sometimes it is a matter of making a few minor adjustments that can allow these windows to operate smoothly once more and save homeowners money on energy costs.

Sash Weights
Sash weights can be replaced to improve the operation of your window sash and reduce the energy cost. Sash weights consist of heavy lead or iron cylindricals that are contained inside a concealed cavity, and connected by ropes to the movable window sash. These weights function as counterbalances, allowing you to open and close the window without the need for mechanical or electrical devices. When they fail, sashweights tend to be left unnoticed or disabled by homeowners.
A weight from a sash that fell out of the cavity is difficult to recover It is therefore important to find a new one that fits correctly. You will also require a new piece of string, a length sashcord and a few sashpulleys to secure the new weights to the cord.
Mortise and Tenon joints are used to join old wood windows. Pin punch and hammer can be used to cut off the wood pegs that hold the components together. 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 made use of glue instead of pins. They can be cut by using a knife and mallet.
Once the sash is freed then you can take out the sash stop and gain access to the weight pocket. This is usually done through tiny holes at the bottom of each jamb. The hole is then covered with an access panel of wood which can be removed to let you view the inside of the frame.
Once you have the sash stopped and the access panel removed, you'll be able to remove the weight from the sash and replace it with new. First, weigh the sash, as the weights you have might not be the right size. After the new weight is installed you can tie a string around it and then thread it through the pulley of the sash. Then, you can attach the string to your boxed frame. Leave a few inches protruding at the head of the string to allow for future adjustments.
Sash Cords
Most old double glazed window repairs near me-hung windows have a cord or chain connected to the weights that supports and keeps the sashes level within the jamb. Over time, these cords can get damaged and make it difficult to raise windows. A new sash cable can restore the ability to move and lower the sash, and ensure it stays in place when opened.
To replace sash cords, the first step is to remove the access panels from the jambs. These are usually installed by screws or nails and will need to be removed or repositioned. It is possible to remove them with the hammer or chisel however, it is best to lay out dust sheets prior to beginning any work.
After the access panel has been removed, you can start working on the sash. Use a flat bar or chisel to pull the narrow parting beads out of their grooves. These are often wedged in or nailed but can be prised free which is why it's worth your time here. If the sash is still in place, pull the mortise-and tenon joints using a hammer or screwdriver, then remove each wood peg. The sash should move freely now, but it might require some lubrication in order to feel less stiff.
Measure the length of sash chain/sash cord needed to reach the sash slot at the bottom, and the pulley located at the top of the jamb. Cut the chain or cord and secure it in the step 6 above. You can use nail, hammer or screws. However nails are less likely to cause damage.
It's best to leave the original weights if you've purchased a kit that will replace the counterbalance. They are not expensive and easy to install if purchased them at architectural salvage stores. Depending on the dimensions and shape of your window, you might need to install one or two sashweights in order to keep it open.
