Weather Stripping

Wood window sashes provide the classic look to your home. If properly maintained, they can last for many years.

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). Take the sash off and mark its width and height so you can find a replacement weather stripping that matches.

Then, remove the sash from its holder, and place it on an even surface that allows you to access all four sides. If your sash was double-hung, remove the ropes and weights that should be buried inside the jamb lining. After you have removed the sash using the utility knife, take off the weather stripping from the old sash by hand or using the putty blade.

Once the sash has been cleared, you can install the parting stops. These are long pieces that split 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 scrap wood.

After removing the stopper for the parting and trimming it to length, apply a thin coat of glazing compound to the bottom of the sash. Smooth the compound with your putty knife and let it dry for at least a day. Once the putty has fully cured, you can apply a topcoat of acrylic latex. This will protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that supports window sashes prone to wearing out from the wear and tear of use, and the result can be a window or door that can't be opened or closed easily. It's important to know that replacing and repair of this hardware is typically easy and affordable. If a sash is difficult to operate try spraying oil into the jamb channel then open it to see if that solves the issue. If not, the problem is most likely due to the sash balance, and you'll have to take off the sash to gain access to the hardware.

Ideally, window sashes must be able to open and close with minimal effort however, this can be an issue if the weights become worn or if the sash meeting rail isn't properly coated. This problem can be caused by a variety of reasons, such as lack of maintenance or by a mismatched weight rating for a particular window sash.

If the hinges on a Window Replacement Near Me begin to sag this could cause the sash to drag and then hit the frame at the opposite corner (Photo 1). To resolve this problem, first ensure that the sash is squarely inserted into the opening of the frame and then remove it from the window. If the sash is fixed to the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Due to hinges that are sagging, and a general deficiency in energy efficiency, windows that are old particularly those in older homes, can be difficult to open or close. In many cases it is a matter of making a few minor adjustments that can make these windows operate smoothly again and help homeowners save money on energy costs.

It is crucial to have the tools you require before you start. Start by marking the location of the hinge channel on the frame using a pencil (Photo 1). This will help you get the channel back in position correctly after you've completed. Remove the sash, and remove all the hardware, including the beads for parting cords, chains, and cords that keep the sash in place.

Sash Weights

If your window sash repairs are to replace a broken cord or just to ensure that the windows are functional by replacing worn out sash weights will improve sash operation and cut down on energy consumption. Sash weights are made of heavy lead or iron cylinders that are enclosed inside a concealed cavity, and are connected via ropes to the moveable window sash. They provide counterbalance that allows the window replacement near me to be closed and opened without using mechanical or electrical devices. If they fail, sashweights tend to be left unnoticed or disabled by homeowners.

It is difficult to recover a sash-weight that has fallen from the cavity, so you'll want to find one that fits properly. You will also need an additional piece of string, a length sash cord, and a few sash pulleys to connect the new sash weights to the sash cord.

Older wood windows are joined with mortise and tenon joints. Hammers and pins can be used to take out the wood pegs holding the parts together. The majority of them are large on one side and smaller on the other. It is crucial 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 through the glue line with a knife, then tapping the mortised part loose with a mallet.

After the sash has been removed then you can take out the stopper on the sash and get access to the weight pocket. This is usually done through a small hole in the bottom of each jamb. This hole is covered with a wooden panel that can be removed to reveal the inside workings.

After the sash has been stopped and the access panel is removed, you can take off the old weight and replace it. Weigh the sash first, as the weights you've got may not be the correct size. Once the new weight is installed then tie a string to it and thread it through the pulley of the sash. Then attach the string to the frame, but only leave a few inches of string sticking out from the head to allow for future adjustments.

Sash Cords

Most old double-hung windows have a cord or chain connected to the weights that keeps the sashes level in the jamb. Over time, these cords may become damaged and make it impossible to raise windows. A new sash cable will restore the ability to raise and lower the sash and keep it in place when it is opened.

The first step to replace sash cords is to find and remove the access panels in the jambs. These are usually attached by nails or screws and require removal. It is possible to remove them using a hammer or chisel, but it is always best to lay out dust sheets prior to beginning any work.

Once the access panel is removed, you can start working on the sash. Take the narrow beads (also known as "tie rails") out of their grooves using a chisel or flat bar. They are usually wedged in or nailed but can be snipped out, so it's worth taking your time here. If the sash remains in place, break the mortise and tenon joints free with a screwdriver or hammer, then remove each wood peg. The sash should move around freely now, however it might require some lubrication to feel less stiff.

Measure the length of sash chain/sash cord needed to reach the sash slot at the bottom from the pulley located at the top of the jamb. Cut the chain or cord and then secure it in the previous step. You can use nail, hammer or screws. However, nails are less likely to cause damage.
