The sash is an interior framing that can be moved vertically upwards or downwards in windows that are open. This article will show you how to perform simple sash repairs.

Weather Stripping

Wood window sashes add a classic aesthetic to your home. When properly maintained, they will last for a long time. However, they can get damaged or deteriorated over time due to exposure and normal wear. Sash repair experts can restore windows to their original condition and keep them looking great longer than replacement windows.


repairmywindowsanddoors.co.uk to repair sash windows is to address weather stripping, which is found on both the sash as well as the frame. If it's damaged or worn out, it can lead to drafts and other issues. To fix it, begin by finding your window brand and glass manufacturer date (etched in the corner of the glass or on the aluminum spacer between panes). Take the sash off, and mark its size and width so that you can purchase new weather stripping that is compatible with the original.

Next, remove the sash and set it on a surface to allow access to all four sides. If your sash has a double-hung, you'll also need to take off the weights and their ropes that should have fallen into the pocket that was intended to be in the jamb liner. After removing the sash with the utility knife, remove the old weather stripping by hand or using a putty blade.

After the sash is cleaned, you can replace the parting stops. They are long pieces of wood that separate the two sashes. Pam likes to replace these with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard. However, you can also use scrap wood.

After removing the stopper for the parting and cutting it to length after which, apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using a putty knife, and let it dry for at least a day. After it has fully dried and dried, apply a second coat of acrylic latex paint. This coating will protect the putty and give your sash a fresh appearance.

Sash Hardware

The hardware that supports window sashes is susceptible to wear and tear from the wear and tear of use and the result could be a window or door that isn't able to open or close easily. The good news is that repairing and replacing this hardware is usually quite simple and inexpensive. If a sash is difficult to operate try spraying oil into the jamb channel, and then slide it open to see if that resolves the issue. If not, the issue is most likely due to the sash balance, and you'll need to take out the sash to gain access to this hardware.

The ideal situation is for window sashes to 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 glazed. This problem can be caused by a number of reasons, such as the lack of maintenance or the wrong weight rating for a particular window sash.

If the hinge arms of a window begin to slide, this could cause the sash to drag and eventually strike the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To address this problem, first ensure that the sash is squarely inserted into the opening of the frame and then take it out of the window. If the sash is secured to the hinge arm, you'll have to loosen the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).

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

It is crucial to have the tools you require before you begin. Mark the location of the hinge channel on the frame (Photo 1) with pencil. This will assist you in getting the channel back in position correctly after you've completed. Then, remove the sash and remove the hardware including the parting beads (Photo 2) and the cords or chains that hold it in place. Soften any putty that has been hardened with a heat gun set to medium and equipped with an nozzle shield. Remove the old sash and put it in a labelled bag.

Sash Weights

Sash weights can be changed to enhance the efficiency of your window sash and decrease the energy cost. Sash weights are made of heavy iron or lead cylinders that are encased in a hidden cavity and are connected via a rope to the movable window sash. These weights function as counterbalances, which allows you to open and shut the window without having to use mechanical or electrical devices. If they fail, sashweights tend to be neglected or not used by homeowners.

A sash weight that has fallen out of the cavity is difficult to retrieve and you'll need to locate a new one that fits properly. You will also require a new piece string, a length of sashcord and a few sashpulleys to secure the new weights to the cord.

Mortise and Tenon joints are used to join old wood windows. The wood pegs that hold the components together can be removed by the use of a pin punch and hammer. The majority of them have large diameters on one side and a smaller one on the other, which is why it is essential to remove the smaller-diameter ones first. Later sashes utilized glue instead of pins. They can be separated by using a knife and mallets.

After the sash is removed and removed, you can take off the stopper on the sash and get access to the weight pocket. This is typically done by drilling tiny holes at the bottom of every jamb. The hole is then covered with the wooden panel which can be removed to reveal the interior workings.

When the sash has been shut off and the access panel is removed, you can take off the weight you used and replace it. Weigh the sash first because the weights you have might not be the right size. After the new weight is installed then tie a string to it and thread it through the pulley of the sash. Then nail the string to the frame, but leave a few inches of string sticking out from the head for future adjustment.

Sash Cords

In the majority of double-hung windows, a cord or chain is connected to the weights. This supports and keeps the sashes of the jamb level. As time passes, these cords may break, making it impossible to raise the window. A new sash cord will give you the ability to move the sash up and down and hold it in place when opened.

The first step to replace cords for sash is to locate and remove the access panels within the jambs. They are usually installed by screws or nails and must be removed or relocated. It is possible to remove them using the hammer or chisel but it is always better to lay out dust sheets prior to beginning any work.

After you have removed the access panel, you can begin to work on the sash. Make the small parting beads (also called "tie rails") out of their grooves using flat bar or chisel. These are often wedged in or nailed but can be prised free which is why it's worth your time. If the sash is still in place, pull the mortise-and-tenon joints out using a hammer or screwdriver, then remove each wood peg. The sash should be able move around freely now, however it may need some lubrication in order to feel less stiff.

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

Unless you've bought an item that replaces the counterbalance system that was in place before, it is recommended to keep the original balancing weights in place. It's cheap to purchase them from a salvage store and they will be easy to install once you've got the sash opened. Based on the size and shape of your window you might need to install one or two sashweights to keep the sash open.
