Weather Stripping

Wood window sashes give the classic look to your home. When properly maintained, can last for a long time. They may, however, get damaged or deteriorated over time, due to exposure and normal wear and tear.

The first step in sash window repairs is addressing weather stripping. It's found on both the sash as well as the frame. If it's loose or worn out, it can lead to drafts and other issues. To fix it, start by determining your window's brand and glass manufacturer date (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 that you can locate the appropriate weather stripping replacement to match.

Then, remove the sash from the holder and place it on an even surface that allows you to access all four sides. If your sash has a double glazed window repairs near me-hung, you'll have to remove the weights and the ropes that go with them that should have fallen into the pocket of the jamb liner. After you have removed the sash using the utility knife, remove the old weather stripping by hand or using a putty blade.

When the sash is clean, you can replace the parting stops. These are long pieces that separate the sashes. Pam prefers to use the standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you can substitute a scrap piece of wood.

After removing the stoppers for parting and trimming them to your desired length then apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound using your putty knife, and allow it to dry for at least one day. After it has fully dried and dried, apply a second coat of acrylic latex paint. This will protect the putty, and give your sash a fresh appearance.

Sash Hardware

The hardware that supports window sashes is susceptible to wear and tear from the wear and tear of use and the result could be a door or window that isn't able to open or close easily. It's good to know that replacing and fixing this hardware is usually straightforward and cost-effective. If a sash is difficult to operate you can try spraying some grease into the jamb channel and then open it to see if it solves the issue. If the problem persists it's likely the sash balance. You will need to remove the window sash to reach this hardware.

Sashes for windows should be able to open and close without much effort. However, this could be difficult if the weights are worn out or the sash-to rail connecting rail isn't coated. This issue could be caused by a variety of things, such as insufficient maintenance or a mismatched weight rating for the specific sash.

If the hinge arms of a window begin to lose their elasticity, this could cause the sash to drag and eventually strike the frame in the corner in the opposite direction of the hinge arm (Photo 1). To address this problem, first ensure that the sash fits squarely in the frame's opening and then take it out of the window repair. If the sash is screwed to the hinge arm, you'll have to loosen the hinge arm 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 especially in older homes, can be difficult to open and close. In most instances, a few minor repairs can transform these windows into smooth operators and save homeowners cash on energy costs.

It is important to have the tools needed 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 correct position after you've finished. Remove the sash and take out all the hardware, including the parting beads cords, chains, and cords that keep the sash in place.

Sash Weights

If your window sash repairs are to replace a damaged cord or just to ensure that the windows are functional, replacing worn out weights for sash will improve its operation and cut down on the energy cost. Sash weights are hefty lead or iron cylinders that are enclosed inside a hidden compartment and attached to the movable the sash with a rope. They are counterbalancers that allows the window to be opened and closed without the use of electrical or mechanical devices. If they fail, sashweights are usually neglected or not used by homeowners.

It's not easy to retrieve the sash-weight that fell from the cavity, so you'll need to find one that fits correctly. You will also require a new 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 using mortise and tenon joints. Pin punch and hammer can be used to remove the wood pegs that hold the components together. The majority of these pegs have an enormous diameter on one side and a smaller diameter on the other, so it is important to remove the smaller-diameter sides first. Later sashes made use of glue instead of pins. They can be separated with a knife and mallet.

Once the sash is freed then you can take out the sash stop and gain access to the weight pocket. Usually this is accomplished by drilling an opening in the bottom of each jamb. This hole is covered by an access panel of wood that can be cut off to allow you to see the inner workings of the frame.

After you have the sash stopped and the access panel removed, you will be able to remove the weight of the old sash and replace it with new. Make sure you weigh the sash before you do this, since the old weights may be a different size than the one you need. After the new weight is in place, tie a string to it and then thread it through the sash pulley. Then, nail the string to the boxed frame. Leave a few inches of space at the head of the string to allow for future adjustments.

Sash Cords

The majority of double-hung windows with a history have a cord or chain attached to the weights which helps keep the sashes in balance within the jamb. As time passes, these cords can get damaged and make it difficult to raise windows. A new sash cord will restore the ability to move the sash up and down and keep it in position when it is opened.

The first step to replace sash cords is to find and take out the access panels located in the jambs. These are usually attached by nails or screws and need to be removed. It may be possible to remove them using the hammer or chisel however, it is best to lay out dust sheets prior to beginning any work.

Once the access panel is removed, you can begin working on the sash. Utilize a flat bar, or chisel, to pry the small partsing beads out of their grooves. It is important to be patient because they are usually stuck or nailed to the floor. 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 each piece. You should be able to move the sash around freely, although it will probably need some oil if it feels stiff.

Take a measurement of the length of sash cord/chain required to reach the sash slot at the bottom of the pulley on the top of the jamb. Cut the cord/chain and then attach it in the previous step. You can employ a hammer, nail or screws, but nails are less likely to cause damage.

It is recommended to keep the original weights in place unless you have purchased a kit to replace the old counterbalance. They're not expensive and are easy to install if you buy them from salvage shops for architectural use. Depending on the size and shape of your window you might need to install one or two sashweights to keep the sash open.
