The sash is the interior frame that is vertically moved either up or down in windows that open. This article will demonstrate how to carry out a few simple upvc repairs to sash.

Weather Stripping

Wood window sashes provide the classic look to your home. If properly maintained, can last for a long time. They can, however, become damaged or degraded with time due to exposure and normal wear. Sash repair specialists can restore windows back to their original condition and maintain their beauty longer than replacement windows.

The first step in repair sash windows is to address weather stripping. It's found on both the sash and frame. If it's loose or worn out, it can lead to drafts and other problems. Start by identifying the window's brand and the date of manufacture for the glass (etched on the glass's corners, or the aluminum spacers between panes). Then, remove the sash and mark its width and height to find replacement weather stripping to match.

Then, take the sash from its holder and place it on flat surfaces to allow you to access all four sides. If your sash has been double-hung, you must remove the ropes and weights that should fall into the pocket within the jamb lining. Once you've taken the sash off and the weights, use a utility knife to cut away the weather stripping from the corners, and then remove it manually or using a putty blade.

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

After removing the stopper and trimming it to length after which, apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound with your putty knife, then let it dry for at least a few days. After it has fully dried, apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a new look.

Sash Hardware

The hardware that holds the window sashes may wear out with time and use. This can result in a door or a window that is difficult to open or close. It's important to know that replacing or repair of this hardware is typically simple and inexpensive. If you're having trouble opening a sash spray some lubricant into the jamb channel. Then slide the sash out to see if it resolves the problem. If not, the issue is likely with the balance of the sash and you'll have to take off the sash to gain access to the hardware.

Window sashes should be able to open and close with minimal effort. However, this may be difficult if the weights are worn out or the sash-to rail connecting rail isn't properly coated. This could be caused by a variety of factors such as an absence of maintenance or an unmatched weight rating.

If the hinges on the Window Doctor begin to move, this could cause the sash to drag, and then eventually to hit the frame at the opposite corner (Photo 1). To fix this issue, first make sure the sash is squarely inserted into the frame's opening and then take it out of the window. If the sash is attached to the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Due to sagging hinges, and a general lack in energy efficiency, old windows, especially those in older houses, could be difficult to open and close. In many instances, a few minor repairs can turn these windows into smooth operation for the first time and save the homeowner money on energy costs.

To complete these repairs to the sash it is essential to have all the necessary tools lined up before you begin. Mark the location of the hinge channel on the frame (Photo 1) using pencil. This will make it easier to position the channel in the correct position after you've finished. Remove the sash, and then remove the hardware, including the parting beads (Photo 2) and the chains or cords that hold it in place. Soften any putty that has been hardened with an electric heat gun set to medium and equipped with an nozzle shield. Remove the old sash, and store it in an bag that is labeled.

Sash Weights

Sash weights can be changed to enhance the efficiency of your window sash and decrease energy costs. Sash weights are composed of heavy iron or lead cylinders that are encased in a hidden cavity and are connected via ropes to the moveable window sash. These weights provide counterbalance which allows the window to be shut and opened without the need for mechanical or electrical devices. When they fail, sashweights are often neglected or not used by homeowners.

It's difficult to retrieve a sash-weight that has fallen from the cavity, so you'll need to find one that fits correctly. You will also require an additional piece of string, a length the sash cord, as well as some sash pulleys that will tie the new sash weights the sash cord.

Older windows made of wood are joined using mortise and tenon joints. Pin punch and hammer can be used to take out the wood pegs holding the components together. The majority of these pegs are large on one side and smaller on the other. It is crucial to first remove the smaller diameter sides. Later sashes made use of glue instead of pins. They can be cut by using a knife and mallets.

Once the sash has been removed, you can take off the stops on the sash and get access to the pockets for weights. This is typically done by drilling tiny holes at the bottom of every jamb. The hole is then covered with a wooden access panel 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 are able to remove the weight that was previously installed and replace it. Weigh the sash first because the weights you have may not be the right size. After the new weight is in place, tie a string to it and then thread it through the pulley for the sash. Then, you can nail the string to the boxed frame, but leave a few inches of string hanging from the head for future adjustments.

Sash Cords

The majority of double-hung windows with a history include a chain or cord attached to the weights which helps keep the sashes balanced in the jamb. Over time these cords can break, making it difficult to raise the window. A new sash cord can restore the ability to move the sash up and down and hold it in place when it is opened.

To replace sash cords the first step is to remove the access panels from the jambs. They are usually screwed or nailed in and require removal. You may be able to use a hammer or chisel to prise them off however, it is always best to lay down dust sheets before commencing any work.

After you have removed the access panel, you are able to begin working on the sash. Utilize a flat bar, or chisel, to pry the tiny parting beads out of their grooves. It's important to take your time, as these are often wedged or nailed in place. If the sash is still in place, pry out the mortise and tenon joints with pin punch and hammer or screwdriver, then unhook the wood pegs attached to the components. It should now be possible to move the sash around freely, although it may require oiling if it seems stiff.

With the sash open, measure enough sash cord/chain to reach from the pulley in the top of the jamb to the sash slot in the bottom. Cut the chain or cord and secure it in the previous step. You can either employ a hammer, screws or nails, however nails are less likely to cause damage.

If you don't have an item that replaces the old counterbalance system it is recommended to keep the original weights for balancing in place. It's not expensive to buy these from salvage shops for architectural purposes and they'll be simple to install once you have the sash opened. Depending on the size and shape of your window you might need to install one or two sashweights to keep it open.
