Remove the sash and mark its width and height so that you can purchase new weather stripping that is compatible with the original.

Then, you can remove the sash from the holder and place it on a flat surface to allow you to access all four sides. If your sash is double-hung, you'll have to remove the weights as well as their ropes, which should have fallen into the pocket of the jamb liner. After removing the sash with the utility knife, take off the old weather stripping by hand or with a putty knife.

Once the sash is clear and clean, you can put in the parting stops. They are long pieces of wood that separate the two sashes. Pam prefers to use the standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you could also substitute a scrap piece of wood.

After removing the stopper and cutting it to length after which, apply a thin layer of glazing compound on the bottom of the sash. Smooth it out using your putty knife and let it dry for at least a few days. When the putty is fully cure, you can apply a topcoat of acrylic latex. This will help protect the putty, and give your sash a fresh look.

Sash Hardware

The hardware that supports window sashes can wear out over time and use. This could result in a upvc door repairs or a window that is difficult to open or close. The good news is that fixing and replacing this hardware is typically quite simple and inexpensive. If you're having difficulty opening the sash, spray some grease into the jamb channel. Then slide the sash open to see if this resolves the issue. If the issue persists it's most likely the sash balance. It is necessary to remove the window sash in order to access the hardware.

Window sashes should open and close with little effort. However, this may be a challenge if the weights have been worn out or the sash-to-rail connecting rail isn't properly covered with. This problem can be caused by a number of factors, including lack of maintenance or by a mismatched weight rating for the particular window sash.

If the hinge arms of a window begin to lose their elasticity, this could cause the sash's to drag and eventually strike the frame in the corner that's directly opposite the hinge arm (Photo 1). To fix the problem ensure that the sash is aligned in the frame opening, and then remove it. If the sash has been screwed to the hinge arm, you'll have to unscrew 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, older windows especially in older homes, may be difficult to open or close. Sometimes just a few easy fixes can help these windows function smoothly again and save homeowners money on energy bills.

It is essential to have the tools needed before you begin. Mark the hinge channel location on the frame (Photo 1) with pencil. This will help you to position the channel in the proper position after you've finished. Remove the sash and take out all the hardware, including the parting beads cords, chains, and cords that help to hold the sash. Soften any hardened putty using the help of a heat gun set at medium and equipped with a nozzle shield. Remove the old sash, and store it in an labelled bag.

Sash Weights

Whether your window sash repairs are to replace a damaged cord or to keep your windows functioning, replacing worn out weights on sash can improve sash operation and help reduce energy costs. Sash weights are composed of heavy iron or lead cylindricals that are contained in a concealed cavity and attached by ropes to the moveable window sash. They are counterbalancers that allows the window to be closed and opened without the use of electrical or mechanical devices. When they fail, sashweights are usually neglected or not used by homeowners.

It's not easy to retrieve an sash-weight which has fallen from the cavity, so you'll need to find one that fits correctly. You will also need an additional piece of string, a length sash cord, and a few sash pulleys to connect the new sash weights the sash cord.

Older wood windows are joined using mortise and tenon joints. Pin punch and hammer can be used to take out the wood pegs holding the parts together. The majority of these pegs are large on one side, but smaller on the other. It is essential to first remove the smaller diameter sides. Sashes that were made later in the century made use of glue instead of pegs. They can be separated by cutting the glue line using an instrument, and then tapping the mortised part loose with a mallet.

Once the sash is freed then you can take out the sash stop and gain access to the weight pocket. Usually it is done by drilling a hole near the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the inner workings.

When the sash has been shut off and the access panel is removed, you are able to remove the weight that was previously installed and replace it. Be sure to weigh the sash prior to you begin, as the weights that were previously used may be different sizes than what is needed. After the new weight has been installed, you can thread an appropriate length of string through the pulling mechanism. Then, you can nail the string to the boxed frame, but only leave a few inches of string sticking out from the head for future adjustments.

Sash Cords

In the majority of double-hung windows the chain or cord is attached to the weights. This supports and keeps the sashes of the jamb in a balanced manner. Over time, these cords could break, making it difficult to raise the window. A new sash cord can restore the ability to move the sash up and down 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. They are usually fixed or screwed in and will need to be removed or relocated. It may be possible to remove them using a 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 start working on the sash. Take the narrow beads (also known as "tie rails") out of their grooves with the chisel or flat bar. They are typically wedged into or nailed but can be snipped out, so it's worth taking your time here. If the sash remains in place, pry out the mortise and tenon joints with the help of a hammer and pin or screwdriver, and then take out the wood pegs that are on each component. The sash should be able to move around freely now, however it might require some lubrication to feel less stiff.

With the sash in an open position Take a measurement of the sash chain to extend from the pulley on the top of the jamb to the sash slot at the bottom. Cut the cord/chain, and then attach it as described in Step 6 above. You can either employ a hammer, screws or nails, however nails are less likely to cause damage.

If you don't have a kit that replaces the counterbalance system that was in place before, it's best to keep the original weights for balancing in place. It's not expensive to buy them from a salvage store and they will be easy to install once you have the sash opened. Depending on the size of your window one or two sashweights could be needed to keep it open.
