Window Sash Repairs

Make sure to check the sashes of your windows regularly for signs of damage, mildew and mold. You can reduce future repair costs by catching these issues early on, before they get out of hand.

The sash is an interior frame that is able to move vertically up and down in windows that open. This article will show you how to carry out a few simple sash repair.

Weather Stripping

Wooden window sashes can give an elegant appearance to your home. They are also durable and last for a long time when they are maintained properly. However, they can become damaged or deteriorate as time passes due to exposure to elements and normal wear and wear and tear. However, sash repair experts can restore your windows back to their original condition and keep them looking fantastic for a longer period of time than replacement windows.

The first step to sash window repairs is addressing weather stripping. It's found on both the sash and frame. If it's worn or loose, out, it could cause drafts, as well as other issues. To fix it, start by determining the brand of your window repair and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Take the sash off and mark its width and height so that you can get replacement weather stripping that matches.

Then, you can remove the sash from its holder, and place it on a flat surface to allow you to reach all four sides. If your sash has a double-hung, you'll have to remove the weights as well as their accompanying ropes that should have fallen into the pocket of the jamb liner. After you've removed the sash using a utility knife, you can use it to remove the old weather stripping at the corners. Then, take it off by hand or with a putty knife.

Once the sash has been cleared, you can install parting stops. These are long pieces of wood that divide the two sashes. Pam prefers to replace them with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard. However, you could also use scrap wood.

After removing the stoppers for parting and trimming them to the desired length then apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound using your putty knife, and let it dry for at least a day. When the putty is fully cured it is possible to apply a topcoat of acrylic latex. This 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 due to time and usage and the result could be a window or door that can't be opened or closed 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 oil into the jamb channel and then slide it open to see if that resolves the issue. If not, the problem is most likely due to the sash balance, and you'll need to remove the sash in order to access this hardware.

Window sashes should be able to open and close with minimal effort. However, this could be a challenge if the weights have been worn out or the sash-to-rail connecting rail isn't properly glazed. This problem can be caused by a number of reasons, such as lack of maintenance or by an incorrect weight rating for the specific window sash.

If the hinge arms of a window begin to lose their elasticity, 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 fix this problem, first ensure that the sash is squarely inserted into the frame's opening and then take it out of the window. If the sash has been attached to the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Because of sagging hinges and a general deficiency in energy efficiency, windows that are old, especially those in older homes, can be difficult to open and close. In many cases, a few simple fixes can make these windows operate smoothly again and save homeowners money on energy costs.

To complete these sash repairs it is essential to have all of the necessary tools in place before you begin. Mark the hinge channel's location on the frame (Photo 1) using a pencil. This will assist you in getting the channel back into position correctly after you've completed. Then, 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 a heat gun set to medium and fitted with an shield for the nozzle. 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 also reduce energy costs. Sash weights are composed of heavy iron or lead cylindricals that are contained inside a concealed cavity, and connected by a rope to the movable window sash. These weights act as counterbalances and allow you to open and shut the window without requiring mechanical or electrical devices. The sash-weights are typically neglected or ignored by homeowners, and are turned into scrap when they break; therefore you may have to search for replacements.

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

Mortise and Tenon joints can be used to join old wood windows. The wood pegs that keep the components together can be removed using pin punches and hammers. The majority of them have an enormous diameter on one side and a smaller diameter on the other, which is why it is crucial to take out the small-diameter sides first. Sashes that were made later in the century utilized glue instead of pegs. They can be separated by cutting through the glue line using the help of a knife, and then tapping the mortised section loose using a mallet.

Once the sash has been removed, you can take off the stops on the sash and get access to the weight pockets. Usually, this is done through an opening at the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the interior workings.

Once you have the sash stopped and the access panel removed, you will be able to take off the weight from the sash and replace it with new. First, weigh the sash to ensure that the weights you have may not be the correct size. Once the new weight is installed you can tie a string around it and then thread it through the pulley for the sash. Then nail the string to the frame, but only leave a few inches of string hanging from the head for future adjustment.

Sash Cords

In the majority of double-hung windows, a chain or cord is attached to the weights. This keeps the sashes within the jamb in a balanced manner. As time passes, these cords may break, making it difficult to raise the window. A new sash cable will restore the ability to raise and lower the sash and ensure it stays in place when it is opened.

The first step in replacing sash cords is to find and remove the access panels in the jambs. They are usually installed by screws or nails and will need to be removed or moved. You could employ a hammer and chisel for removing them but it's best to lay down dust sheets prior to commencing any work.

Once the access panel is removed, you can start working on the sash. Use a flat bar or chisel to pull the tiny partsing beads out of their grooves. These are often wedged in or nailed but can be prised free which is why it's worth your time. If the sash remains in place, break the mortise-and-tenon joints out with a screwdriver or hammer and then take out each wood peg. The sash should move freely now, but it might require some lubrication to make it feel less stiff.

With the sash in an open position, measure enough sash cord/chain to extend from the pulley at the top of the jamb to the sash slot at the bottom. Cut the chain or cord and attach it in the previous step. You can do this with a hammer, nails, or screws. However, nails are less likely to cause damage.

If you haven't purchased a kit that replaces the old counterbalance system it's recommended to keep the original weights for balancing in place. It's not too expensive to purchase these from salvage shops for architectural purposes and they will be easy to install once you've got the sash opened. Depending on the size of your window two or three sash weights could be needed to keep the sash in an open position.
