Window Sash Repairs

Check the windows sashes regularly for damage, mildew, and mold. By catching these problems early you will save money on future upvc repairs.

The sash is an inside frame that is able to move up and down vertically in windows that are open. This article will show you how to make several simple sash upvc repairs.

Weather Stripping

Wooden window sashes can add an elegant look to your home. They are also durable and will last for many years when they are maintained properly. However, they can be damaged or degrade as time passes due to exposure to elements and wear and wear and tear. Sash repair experts can restore windows to their original state and keep them looking great much longer than replacement windows.

Weather stripping is the most important thing to address when repairing windows that have sash. It's located on both the frame and the sash. It could cause drafts if worn out or loose. Start by identifying the window's brand Window Doctor and the manufacturer's date (etched on the glass's corner or the aluminum spacers between panes). Remove the sash and mark its width and height so you can purchase replacement weather stripping that matches.

Then, you can remove the sash from the holder and place it on a flat surface to allow you to reach all four sides. If your sash has been double-hung, you must remove the weights using their ropes that should be buried inside the jamb lining. After you've removed the sash using a utility knife, you can use it to cut away the old weather stripping at the corners. Then, remove it manually or using a putty knife.

After the sash is cleaned, you can replace the parting stops. These are long pieces of wood that divide the two sashes. Pam prefers standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you could substitute a scrap piece of wood.

After removing the stoppers for parting and cutting them to the desired length then apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound using your putty tool, and allow it to dry for at least one day. Once the putty has fully dried it is possible to apply a topcoat of acrylic latex. This will protect the putty, and give your sash a fresh appearance.

Sash Hardware

The hardware that supports window sashes may wear out with time and use. This could result in a door or a window that is difficult to open or close. The good news is that repairing and replacing this hardware is usually very simple and cost-effective. If you're having trouble opening a sash, spray some oil into the jamb channel. Then slide the sash open to see if it resolves the problem. If not, the problem is likely with the balance of the sash and you'll need to take out the sash in order to access the hardware.

Ideally, window sashes should move open and shut with minimal effort however, this can be a difficult task if the weights become worn or if the sash that joins rail isn't properly glazed. This issue can be caused by a variety of factors, including insufficient maintenance or an incorrect weight rating for a particular sash.

If the hinge arms of a window are beginning to slide, this could cause the sash to slide and eventually strike the frame in the corner that's opposite the hinge arm (Photo 1). To resolve this problem, first ensure that the sash fits squarely in the opening of the frame and then remove it from the window. If the sash is screwed to the hinge arm, you'll need to loosen the hinge arm and replace it (Photo 2). Next, install the new sash (Photo 3).

Due to sagging hinges, and a general deficiency in energy efficiency, old windows particularly those in older houses, could 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 and help homeowners save money on their energy bills.

It is crucial to have the tools you require before you start. Begin by marking the location of the hinge channel on the frame using a pencil (Photo 1). This will help you get the channel back into position correctly after you've completed. Remove the sash and then remove all hardware including the parting beads, cords, and chains that help to hold the sash. A hot gun with nozzle shield and a medium setting will soften any hardened glue. Remove the old sash and store it in an bag with a label.

Sash Weights

Sash weights are able to be replaced to enhance the efficiency of your window sash, and also reduce energy costs. Sash weights are composed of heavy iron or lead cylinders that are encased in a concealed cavity and attached by ropes to the moveable window sash. These weights act as counterbalances and allow you to open and shut the window without the need for mechanical or electrical devices. When they fail, sashweights tend to be left unnoticed or disabled by homeowners.

A sash weight that has fallen out of the cavity is difficult to retrieve and you'll need to locate a new one that is suitable for the. You will also require a new piece string, a length 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. The wood pegs that hold the parts together can be removed using a pin punch and hammer. Most of them have an enormous diameter on one side and a smaller one on the other, which is why it is crucial to take out the smaller-diameter ones first. Sashes that were made later in the century made use of glue instead of pegs and can be separated by cutting the glue line using the help of a knife, and then tapping the mortised part loose using mallets.

After the sash has been removed and removed, you can take off the stopper on the sash and get access to the weight pocket. This is usually done via tiny holes in the bottom of each jamb. This hole is then covered by an access panel made of wood that can be cut off to let you view the inside of the frame.

After the sash has been stopped and the access panel is removed, you can take off the old weight and replace it. Be sure to weigh the sash first, as the weights you have may not be of the right size. After the new weight has been installed, run the string through the sash pulling mechanism. Then, you can attach the string to your boxed frame. Leave a few inches at the end of the string to allow for future adjustments.

Sash Cords

The majority of double-hung windows with a history include a chain or cord attached to the weights which supports and keeps the sashes balanced within the jamb. Over time, these cords could break, making it impossible to raise the window. A new sash cord can restore the ability to move the sash upwards and downwards and hold it in position when it is opened.

The first step in replacing cords for sash is to locate and remove the access panels in the jambs. These are usually screwed or nailed in and need to be removed. 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.

Once the access panel is removed, you can begin working on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves with the chisel or flat bar. It is important to be patient as they're often stuck or nailed to the floor. If the sash is in place, pry out the mortise and tenon joints using pin punch and hammer or screwdriver, then remove the wood pegs attached to each piece. The sash should be able to move around freely now, however it may require some lubrication to make it feel less stiff.

Take a measurement of the length of the sash chain or sash cord needed to reach the sash slot on the bottom, and the pulley located at the top of the jamb. Cut the cord/chain and then attach it in Step 6 above. You can use either a hammer, nails or screws. However nails are less likely to cause damage.

It's best to leave the weights that came with the original counterbalance unless you've purchased a kit to replace the old counterbalance. They're not costly and are easy to install if purchased them at architectural salvage stores. Depending on the size of your Window Doctor two or three sash weights may be needed to keep it in an open position.
