Window Sash Repairs

Make sure to check the sashes of your windows regularly for any damage, mildew and mold. You can reduce future repair costs by catching problems in the early stages, before they become too much.

The sash is the internal framing that can be moved vertically either up or down in windows that are open. This article will show you how to do easy repairs to your sash.

Weather Stripping

Wood window sashes add a classic aesthetic to your home. If properly maintained, can last for a long time. They can, however, get damaged or deteriorated over time due to exposure and normal wear and tear. Sash repair specialists can restore windows to their original state and maintain their appearance much longer than replacement windows.

The first step to repair sash window damage is to fix weather stripping, which can be found on both the sash as well as the frame. If it's worn or loose, out, it could cause drafts and other issues. Start by identifying the brand of window and the manufacturer's date (etched on the corner of the glass or the aluminum spacers between panes). Then, remove the sash and mark its height and width to find replacement weather stripping to match.

Then, remove the sash and set it on a surface so you can access 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 which should have slipped into the intended pocket in the jamb liner. After removing the sash with the utility knife, remove the old weather stripping by hand or using a putty knife.

Once the sash has been cleaned, you can replace the stoppers that separate the two sashes. These are long pieces that split the sashes. Pam prefers to use standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you could also use a scrap piece of wood.

After removing the stopper for the parting and trimming it to length, apply a thin coat of glazing compound to the bottom of the sash. Smooth out the compound using your putty knife, then let it dry for at least a day. After the putty has completely cured, you can apply an acrylic latex topcoat. This coating will protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that supports window sashes is susceptible to wear and tear from the wear and tear of use, and the result can be a window or door that won't open or close easily. The good news is that fixing and replacing this hardware is generally relatively easy and affordable. If a sash becomes difficult to operate, try spraying some oil into the jamb channel then open it to see if it resolves the issue. If not, the issue is most likely due to the balance of the sash and you'll need to remove the sash to access the hardware.

The ideal situation is for window sashes to move open and shut with minimal effort but this is difficult if the weights become worn or if the sash that joins rail isn't properly coated. This issue can be due to many factors, including a lack of maintenance and an unmatched weight rating.

If the hinge arms of a window are starting to slide, this could cause the sash's to drag and eventually land on the frame in the corner that's directly opposite the hinge arm (Photo 1). To correct the issue ensure that the sash is centered in the frame opening and then take it off. If the sash has been screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Because of sagging hinges and a general lack of energy efficiency, older windows particularly those in older houses, could be difficult to open and close. In many cases just a few easy fixes can help these windows function smoothly once more and help homeowners save money on energy costs.

It is crucial to have the tools you need before you start. Mark the hinge channel's location on the frame (Photo 1) with a pencil. This will make it easier to position the channel in the correct position after you've finished. Then, remove the sash and remove the hardware including the beads that separate (Photo 2) and the cords or chains that hold it in place. A hot gun with nozzle shield and medium setting will soften any hardened glue. Remove the old sash and place it in a bag that is labeled.

Sash Weights


Sash weights can be changed to improve the operation of your window sash and decrease the energy cost. Sash weights are made of iron or lead cylinders that are enclosed in a concealed cavity and connected by ropes to the moveable window sash. These weights function as counterbalances, allowing you to open and close the window without requiring mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners and then turned into scrap when they fail. Consequently, you may need to search for replacements.

A weight in a sash that has fallen out of the cavity is difficult to recover and you'll need to locate a new one that is suitable for the. You will also require a fresh piece of string, a length of sashcord and some sashpulleys to tie the new weights to the cord.

Older wood windows are joined by mortise and tenon joints. The wood pegs holding the components together can be removed using a pin punch and hammer. The majority of these pegs are large on one side, and smaller on the other. It is important to remove first the smaller diameter sides. Sashes that were made later in the century utilized glue instead of pegs and can be separated by cutting through the glue line with a knife, then tapping the mortised area loose using mallets.

Once the sash has been released, you can remove the sash stops and gain access to the pockets for weights. Usually this is accomplished by drilling an opening in the bottom of each jamb. The hole is then covered with a wooden access panel 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 of the old sash and replace it with new. Weigh the sash first to ensure that the weights you have may not be of the right size. Once the new weight is in place then tie a string to it and then thread it through the pulley for the sash. Then, nail the string to the boxed frame. Leave a few inches protruding at the end of the string for future adjustments.

Sash Cords

In the majority of old double-hung windows, a cord or chain is affixed to the weights. This helps keep the sashes within the jamb balanced. Over time, these cords could break, making it difficult to raise the window.  window repair  will give you the ability to move the sash upwards and downwards and keep it in place when 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 must be removed. It may be possible to remove them using the hammer or chisel but it is always best to lay out dust sheets prior to starting any work.

After you have removed the access panel, you are able to begin to work on the sash. Utilize a flat bar, or chisel to pry the tiny parting beads out of their grooves. They are typically wedged into or nailed but can be removed, so it's worth taking your time. If the sash is still in place, break the mortise-and-tenon joints out using a hammer or screwdriver and then remove each wood peg. The sash should move freely now, but it may need some lubrication to feel less stiff.

Measure the length of sash chain/sash cord needed to reach the sash slot at the bottom, and the pulley on the top of the jamb. Cut the cord/chain and then attach it in the previous step. You can use a hammer and nail or screws, but nails are less likely to cause damage.

It is recommended to keep the weights that came with the original counterbalance unless you've purchased a kit to replace the old counterbalance. It's not expensive to buy these from salvage shops for architectural purposes and they will be easy to install once you have the sash unlocked. Based on the size of your window, one or two sash weights may be needed to keep it in an open position.
