Window Sash Repairs

Check the windows sashes regularly for damage, mildew, and mold. You can avoid the cost of repairs in the future by catching these issues early on, before they become out of control.

The sash is the internal framing that moves vertically either up or down in windows that open. This article will demonstrate how to carry out a few simple repairs to sash.

Weather Stripping

Wood window sashes give a classic aesthetic to your home and, when properly maintained, they will last for many years. They may, however, be damaged or degraded over time, due to exposure and normal wear and tear. Sash repair experts can restore windows back to their original condition and maintain their appearance much longer than replacement windows.

The first step for sash window repairs is addressing weather stripping. It's found on both the sash and frame. It can cause drafts if worn out or loose. Start by identifying the window brand and the date of manufacture for the glass (etched on the glass's corners or on the aluminum spacers between panes). Remove the sash, and mark its size and width so that you can find a replacement weather stripping that matches.

Then, remove the sash and set it on a surface so you can access all four sides. If your sash was double-hung, remove the weights using their ropes that should fall into the pocket in the jamb lining. Once you've taken the sash off using a utility knife, you can use it to remove the old weather stripping at the corners, then take it off by hand or using a putty knife.

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

After removing the stoppers for parting and trimming them to your desired length then apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound with your putty knife, and then let it dry for a minimum of a day. When the putty is fully dried, you can apply a topcoat of acrylic. This will help protect the putty, and give your sash a modern look.


Sash Hardware

The hardware that supports window sashes is prone to wearing out from age and use, and the result can be a door or window that can't be opened or closed easily. It's important to know that replacing or repairing this hardware is often simple and inexpensive. If you are having trouble opening a sash, spray some oil into the jamb channel. Then, slide the sash up and open to see if that fixes the problem. If not, the problem is most likely due to the sash balance, and you'll need to take out the sash to access this hardware.

Sashes for windows should be able to be able to open and close with minimal effort. However, this could be difficult if weights are worn out or the sash connecting rail isn't glazed. This issue could be caused by a variety of factors, including a lack of maintenance and a mismatched weight rating.

If the hinge arms of a window are beginning to slide, this could cause the sash's to drag and eventually land on the frame in the corner opposite the hinge arm (Photo 1). To fix the problem, make sure that the sash is centered in the frame opening, and then remove it. If the sash was attached to the hinge arm, remove the hinge and replace it. (Photo 2). Then, put in the new sash (Photo 3).

Due to sagging hinges, and a general deficiency in energy efficiency, old windows especially in older homes, can be difficult to open and close. In many cases just a few easy fixes can help these windows function smoothly again and save homeowners money on energy bills.

It is essential to have the tools needed before you start. Mark the location of the hinge channel on the frame (Photo 1) with pencil. This will assist you in getting the channel back into the correct position after you've finished. Remove the sash and then remove all hardware, including the parting beads cords, chains, and cords that hold the sash in place. Heat gun with nozzle shield and a medium setting will soften any hardened putty. Remove the old sash and store it in a bag labeled.

Sash Weights

Sash weights can be replaced to improve the performance of your window sash and decrease the cost of energy. Sash weights are hefty lead or iron cylinders, which are enclosed in a concealed cavity and linked to the moveable window sash using a rope. These weights act as counterbalances, which allows you to open and shut the window without having to use mechanical or electrical devices. When they fail, sashweights tend to be left unnoticed or disabled by homeowners.

A weight in a sash that has fallen out of the cavity is difficult to recover, so you will want to find a replacement that fits properly. You will also need a new piece of string, a length of the sash cord, as well as some sash pulleys to tie the new sash weights onto the sash cord.

Older windows made of wood are joined with mortise and tenon joints. The wood pegs that keep the parts together can be removed by the use of a pin punch and hammer. Most of these pegs have a large diameter on one side and a smaller diameter on the other side, so it is important to remove the smaller-diameter sides first. Sashes that were made later in the century utilized glue instead of pegs and can be separated by cutting through the glue line with the help of a knife, and then tapping the mortised area loose with a mallet.

After the sash is released, you can remove the stops on the sash and get access to the weight pockets. Usually this is accomplished by drilling an opening at the bottom of each jamb. This hole is covered with the wooden panel which can be removed to reveal the inner workings.

Once you have the sash stopped and the access panel removed, you will be able to remove the old sash weight and replace it with new. Be sure to weigh the sash first, as the weights you've got may not be the correct size. After the new weight is installed then tie a string to it and thread it through the pulley for the sash. Then, you can nail the string to the frame, leaving a few inches of string protruding from the head for future adjustments.

In most old double-hung window the chain or cord is affixed to the weights. This keeps the sashes in the jamb balanced. As time passes, these cords may become damaged and make it difficult to raise the windows. A new sash cord will restore the ability to move the sash up and down and will keep it in its place when it is opened.

The first step to replace cords for sash is to locate and remove the access panels in the jambs. They are usually screwed or nailed into and require removal. You might be able to use a hammer or chisel to prise them off but it's best to lay down dust sheets prior to starting any work.

After the access panel has been removed, you can begin working on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves with flat bar or chisel. They are usually wedged in or nailed, but they can be removed and it's worth your time. If the sash remains in place, break the mortise and tenon joints free with a hammer or screwdriver and then remove each wood peg. It should now be possible to move the sash back and forth freely, although it might require oil if it feels stiff.

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

Unless you've bought a kit that replaces the old counterbalance system it's recommended to keep the original weights for balancing in place. They're not costly and simple to install if purchased them from salvage shops for architectural use. Based on the size of your window two or three sash weights might be required to keep the sash in an open position.
