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

Then, take the sash from its holder and place it on an even surface that allows you to reach all four sides. If the sash is double-hung, you'll also need to take off the weights and their accompanying ropes that should have fallen into the intended pocket in the jamb liner. Once you've removed the sash and window the weights, use a utility knife to cut off the weather stripping from the corners, then remove it by hand or using a putty knife.

Once the sash is clear it is time to replace the parting stops. These are long pieces that separate the sashes. Pam prefers to replace them with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard, however you can also replace them with a piece of scrap wood.

After removing the stopper for the parting and cutting it to length after which, apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty knife, and then let it dry for at least a day. After the putty has completely cure and dried, 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 holds window sashes is prone to wearing out from the wear and tear of use and the result could be a door or upvc window repairs that isn't able to open or close easily. It's important to know that replacing and fixing this hardware is usually straightforward and cost-effective. If you're having trouble opening a sash spray some lubricant into the jamb channel. Then, slide the sash out to see if that fixes the problem. If not, the problem is most likely due to the sash balance and you'll have to take off the sash to gain access to the hardware.

Ideally, window sashes should move open and shut 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 coated. This issue can be caused by a number of factors, including insufficient maintenance or the wrong weight rating for the specific window sash.

If the hinges on a window begin to sag this can cause the sash drag and eventually hit against the frame in the opposite corner (Photo 1). To correct the issue ensure that the sash is in the proper position within the frame opening and then take it off. If the sash is screwed to the hinge arm, you'll have to unscrew the hinge arm and replace it (Photo 2). Then, you can install the new sash (Photo 3).

Because of sagging hinges and a general lack of energy efficiency, old windows, especially those in older houses, could be difficult to open or close. In most instances, a few easy repairs can transform these windows into smooth operation again and save the homeowner money on energy bills.

In order to make these repairs to sash it is important to have all the necessary tools in place before you begin. Mark the hinge channel's location on the frame (Photo 1) using pencil. This will assist you in getting the channel back on the correct position after you've finished. Remove the sash and take off the hardware including the parting beads (Photo 2) and the cords or chains that hold it in place. Soften any hardened putty using a heat gun set to medium and equipped with an shield to block the nozzle. Remove the old sash and keep it in a labeled bag.

Sash Weights

No matter if your window sash repair needs are to replace a damaged cord or simply to ensure that the windows are functional, replacing worn out sash weights will improve sash operation and reduce the energy cost. Sash weights consist of iron or lead cylindricals that are contained inside a concealed cavity, and attached by a rope to the movable window sash. These weights function as counterbalances, allowing you to open and close the window without requiring mechanical or electrical devices. If they fail, sashweights are usually left unnoticed or disabled by homeowners.

A weight from a sash that fell out of the cavity is difficult to get back, so you will want to find a replacement that fits correctly. You will also need a new piece of string, a length of sash cord, and a few sash pulleys to connect the new sash weights the sash cord.

Mortise and Tenon joints can be used to join windows made of older wood. Hammers and pins can be used to take out the wood pegs holding the components together. Most of them have large diameters on one side and a smaller size on the other side, so it is crucial to take out the smaller-diameter sides first. Sashes made later in the century utilized glue instead of pegs and can be separated by cutting the glue line with the help of a knife, and then tapping the mortised part loose using a mallet.

Once the sash is freed, you can remove the sash stop and access the weight pocket. Usually, this is done through an opening at the bottom of each jamb. The hole is then covered with an access panel of wood which can be removed so that you can view the inside of the frame.

Once you have the sash stopped and the access panel removed, you'll be able to remove the weight from the sash and replace it with the new. Be sure to weigh the sash first to ensure that the weights you've got may not be the correct size. After the new weight is installed, tie a string to it and then thread it through the pulley for the sash. Then, attach 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

In the majority of old double-hung windows the chain or cord is affixed to the weights. This keeps the sashes within the jamb level. Over time, these cords may become damaged and make it difficult to raise the windows. A new sash cord can restore the ability to move the sash upwards and downwards and hold it in position when it is opened.

To replace sash cords the first step is to remove the access panels from the jambs. These are usually attached by nails or screws and need to be removed. You might be able to use a hammer and chisel to remove them however, it is always best to lay down dust sheets prior to starting any work.

After the access panel has been removed, you can start working on the sash. Take the narrow beads (also called "tie rails") out of their grooves with flat bar or chisel. They are usually wedged in or nailed but can be prised free, so it's worth taking your time here. If the sash remains in place, pry the mortise-and-tenon joints out with a screwdriver or hammer, then remove each wood peg. You should be able to move the sash back and forth freely, although it may require lubrication if it feels stiff.

With the sash open, measure enough sash cord/chain to extend from the pulley at the top of the jamb to the sash slot on the bottom. Cut the cord or chain and attach it in Step 6 above. You can either employ a hammer and nail or screws, but nails are less likely to cause damage.

It is recommended to keep the original weights if you have purchased a kit that will replace the counterbalance that was previously installed. It's not expensive to buy them from a salvage store and they will be easy to install once you've got the sash open. Depending on the size of your window one or two sashweights might be required to keep the sash in an open position.
