10 Things That Everyone Is Misinformed About Window Sash Repairs

Window Sash Repairs

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

The sash is the internal frame that is vertically moved either up or down in windows that are open. This article will teach you how to do a variety of simple repairs to the sash.

Weather Stripping

Wooden window sashes can give an elegant look to your home. They are also durable and last for a long time when they are maintained properly. However, they can be damaged or deteriorate as time passes because of exposure to the elements and wear and tear. Thankfully, sash repair experts can restore your windows to their original condition and maintain their appearance for a longer period of time than replacement windows.

Weather stripping is the first thing to address when repairing windows with sash. It is located on both the frame and sash. It could cause drafts if damaged or is loose. Begin by identifying the window brand and the glass manufacturer's date (etched on the glass's corners, or the aluminum spacers between panes). Then, remove the sash and mark its width and height, so you can find the appropriate weather stripping replacement to match.

Then, take it off and place it on a work surface so you can access all four sides. If your sash has a double-hung, you'll need to remove 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 using the utility knife, you can remove the weather stripping from the old sash by hand or with the putty blade.

Once the sash has been cleared, you can replace parting stops. These are long pieces that separate the sashes. Pam prefers to use the standard 1/2-inch by 3/4 inch window trimming from the lumberyard. However, you could substitute with a scrap piece of wood.

After removing the stopper for the parting and trimming it to length and then apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty tool and let it dry for at least a day. After the putty has completely dried it is possible to apply a topcoat of acrylic latex. This will help protect the putty, and give your sash a modern appearance.

Sash Hardware

The hardware that supports window sashes is prone to wearing out from time and usage, repairs and the result can be a window or door that won't open or close easily. It's good to know that replacing and fixing this hardware is usually easy and affordable. If you're having difficulty opening the sash, spray some grease into the jamb channel. Then, slide the sash up and open to see if this resolves the issue. If the issue continues it's most likely the sash balance. It is necessary to take off the window repair sash to access the hardware.

Window sashes need to open and close with little effort. However, this can be a challenge if the weights have been worn out or the sash-to-rail connecting rail isn't coated. This issue can be caused by a variety of things, such as insufficient maintenance or an incorrect weight rating for the specific sash.

If the hinge arms on windows begin to slide, this can cause the sash drag, and then eventually to hit the frame at the opposite corner (Photo 1). To address this issue, first make sure the sash is squarely inserted into the opening of the frame and then remove it from the window. If the sash has been screwed to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Next, install the new sash (Photo 3).

Due to sagging hinges, and a general lack of energy efficiency, old windows, especially those in older homes, can be difficult to open or close. Many times, a few simple fixes can help these windows function smoothly again and save homeowners money on energy costs.

To complete these repairs to sash it is important to have all the necessary tools lined up before you begin. Start by marking the location of the hinge channel on the frame with a pencil (Photo 1). This will allow you to get the channel back into the correct position after you've finished. Remove the sash, and then remove the hardware including the beads that separate (Photo 2) and the cords or chains which hold it in place. A hot gun with nozzle shield and medium setting will soften any hardened putty. Take off the old sash and put it in a labelled bag.

Sash Weights

If your window sash repairs are to replace a damaged cord or just to ensure that the windows are functional and functional, replacing worn-out weights for sash will improve its operation and help reduce energy costs. Sash weights are heavy, lead or iron cylinders enclosed inside a hidden compartment and attached to the movable window sash using a rope. These weights function as counterbalances, which allows you to open and shut the window without having to use mechanical or electrical devices. The sash weights are often ignored or discarded by homeowners and turned into scrap when they fail. Consequently, you may need to find replacements.

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

Older wood windows are joined with mortise and tenon joints. Hammers and pins can be used to cut off the wood pegs that hold the components together. The majority of these pegs are big on one side and smaller on the other. It is essential to first remove the smaller diameter sides. Sashes made later in the century made use of glue instead of pegs and can be separated by cutting through the glue line with an instrument, and then tapping the mortised area loose with mallets.

Once the sash is freed and removed, you can take off the sash stop and access the weight pocket. Usually it is done by drilling a hole near the bottom of each jamb. This hole is then covered by an access panel made of wood that can be cut off so that you can see the inner workings of the frame.

Once the sash is stopped and the access panel is removed, you are able to remove the weight you used and replace it. Weigh the sash first, as the weights you have may not be of the right size. Once the new weight has been installed, run the string through the sash pulling mechanism. Then attach the string to the boxed frame, but leave a few inches of string protruding from the head for future adjustments.

Sash Cords

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

To replace sash cords the first step is to remove the access panels from the jambs. They are usually screwed or nailed into and need to be removed. You might be able to use a hammer and chisel to remove them, but it's always better to lay down dust sheets prior to starting 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 a chisel or flat bar. They are typically wedged into or nailed, but they can be snipped out which is why it's worth your time here. If the sash is still in place, break the mortise and tenon joints with pin punch and hammer or screwdriver, and then take out the wood pegs on the components. You should be able to move the sash around freely, though it will probably need some oil if it feels stiff.

Determine the length of the sash chain or sash cord needed to reach the sash slot on the bottom of the pulley on the top of the jamb. Cut the cord or chain and attach it in Step 6 above. You can use either nail, hammer or screws. However nails are less likely to cause damage.

If you don't have an upgrade kit to replace the old counterbalance system, it's best to keep the original weights for balancing in place. They are not expensive and are easy to install if you purchase them from architectural salvage stores. Based on the size and shape of your window, you might need to install one or two sashweights in order to keep the sash open.
