The first step to sash window repairs is addressing weather stripping. It's found on both the sash as well as the frame. It can cause drafts if worn out or loose. Begin by identifying the window brand and the manufacturer's date (etched on the glass's corner or on the aluminum spacers between panes). Take the sash off, and mark its width and height so you can get replacement weather stripping that matches.

Next, remove the sash and set it on a work surface to allow access to all four sides. If the sash is double-hung, you'll have to remove the weights as well as the ropes that go with them that should have fallen into the intended pocket in the jamb liner. Once you've removed the sash using a utility knife, you can use it to remove the weather stripping that was formerly in place at the corners, then take it off by hand or using a putty blade.

After the sash has been cleaned, you can replace the parting stops. These are long pieces that separate the sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. However, you can substitute with a scrap piece of wood.

After removing the stopper for the parting and cutting it to length and then apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound using your putty tool and let it dry for at least one day. Once the putty has fully cure, you can apply a topcoat of acrylic latex. This will protect the putty and give your sash a new look.

Sash Hardware

The hardware that supports window sashes is susceptible to wear and tear due to age and use, and the result can be a door or window that isn't able to open or close easily. The good thing is that fixing and replacing this hardware is typically relatively easy and affordable. If you're having difficulty opening a sash, spray some lubricant into the jamb channel. Then, you can slide the sash open to see if that fixes the issue. If not, the problem is likely with the balance of the sash and you'll have to take off the sash in order to access the hardware.

The ideal situation is for window sashes to swing open and closed with very little effort, but this can be a difficult task when the weights are worn or if the sash meeting rail isn't properly glazed. This problem could be caused by many factors, including an absence of maintenance or a mismatched weight rating.

If the hinge arms on a upvc window repair begin to sag this could cause the sash to drag, and then eventually to hit the frame at the opposite corner (Photo 1). To resolve this issue, first make sure the sash is firmly seated in the opening of the frame and then remove it from the window. If the sash is attached to the hinge arm, remove the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

Due to hinges that are sagging, and a general lack of energy efficiency, windows that are old, especially those in older houses, could be difficult to open and close. Sometimes just a few easy fixes can make these windows operate smoothly and save homeowners money on their energy bills.

It is important to have the tools you require before you start. Begin by marking the position of the hinge channel on the frame with pencil (Photo 1). This will help you to place the channel in the correct location after you've completed. Remove the sash and remove the hardware, including the parting beads (Photo 2) and the cords or chains that secure it. Heat gun with nozzle shield and medium setting will soften any putty that has been hardened. Remove the old sash, and put it in a bag labeled.

Sash Weights

Whether your window sash repairs are to replace a damaged cord or to ensure that the windows are functional and functional, replacing worn-out weights on sash can improve sash operation and cut down on energy costs. Sash weights are heavy lead or iron cylinders enclosed in a concealed cavity and attached to the movable window sash using rope. These weights provide counterbalance, allowing the window to be closed and opened without the use of electrical or mechanical devices. The sash-weights are typically disregarded or disabled by homeowners, and are turned into scrap when they fail. Consequently, you may need to locate replacements.

It is difficult to recover 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 new weights to the cord.

Mortise and Tenon joints can be used to join windows made of older wood. The wood pegs that keep the components together can be removed by a pin punch and hammer. Most of these pegs 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 sides first. Later sashes utilized glue instead of pins. They can be separated by using a knife and a mallet.

After the sash is released, you can remove stops on the sash and get access to the pockets for weights. Usually this is accomplished by drilling an opening at the bottom of each jamb. The hole is then covered with an access panel made of wood that can be cut off to let you see the inner workings of the frame.

When the sash has been shut off and the access panel has been removed, you can remove the weight you used and replace it. Be sure to weigh the sash before you do this, since the old weights could be different in size from the one you need. Once the new weight is installed then tie a string to it and thread it through the pulley for the sash. Then, nail the string to the boxed frame. Leave a few inches at the top of the string to allow for future adjustments.

Sash Cords

In most old double-hung window Repair the chain or cord is connected to the weights. This supports and keeps the sashes in the jamb level. Over time, these cords can become damaged and render it impossible to raise the windows. A new sash cord will give you the ability to move the sash up and down and keep it in place when it is opened.

The first step in replacing sash cords is to locate and remove the access panels within the jambs. These are usually attached by nails or screws and must be removed. It may be possible to remove them with an axe or hammer, but it is always better 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 pry the narrow parting beads out of their grooves. It's important to take your time as they're often stuck or nailed to the floor. If the sash is in place, remove the mortise and tenon joints using the help of a hammer and pin or screwdriver, and then take out the wood pegs attached to each piece. The sash should be able to move freely now, but it might require some lubrication to feel less stiff.

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

If you don't have a kit that replaces the old counterbalance system it's recommended to keep the original balancing weights in place. They are not expensive and are easy to install if you buy them from salvage shops for architectural use. Based on the size of your window, one or two sashweights could be needed to keep the sash in an open position.
