Window Sash Repairs

Regularly inspect the window sashes for signs of damage, mildew and mold. You can save the cost of repairs in the future by catching these issues early on before they get out of hand.

The sash is the internal frame that is vertically moved either up or down in windows that open. This article will show you how to make several simple sash repairs.

Weather Stripping

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

The first step in sash window repairs is addressing weather stripping. It's found on both the sash as well as the frame. It can 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 height and width so that you can locate replacement weather stripping to match.

Then, take 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 need to remove the weights and their ropes 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 blade.

Once the sash is clear and clean, you can put in the parting stops. These are long pieces that separate the sashes. Pam likes to replace these with standard 1/2-inch by 3/4-inch window trim from the lumberyard, but you can also use a piece of scrap wood.

After removing the stoppers for parting and trimming them to your desired length then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound with your putty tool and let it dry at least one day. After it has fully dried then apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a new look.

Sash Hardware

The hardware that supports the windows sashes can become worn out over time and use. This can result in windows or doors that is difficult to open or close. The good news is that fixing and replacing this hardware is typically relatively easy and affordable. If you are having trouble opening a sash, spray some lubricant into the jamb channel. Then, you can slide the sash up and open to see if it resolves the issue. If not, the issue is likely with the balance of the sash and you'll have to take off the sash to access the hardware.

Ideally, window sashes must swing open and closed without effort, however, this can be a difficult task if the weights become worn or if the sash meeting rail isn't properly coated. This issue could be caused by a variety of factors, including the lack of maintenance or a mismatched weight rating for a particular sash.

If the hinge arms on the window begin to move, this could cause the sash to drag and eventually hit against the frame in the opposite corner (Photo 1). To remedy the issue, make sure that the sash is centered in the frame opening and then take it off. If the sash was screwed onto the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

Due to hinges that are sagging, and a general deficiency in energy efficiency, windows that are old, especially those in older houses, could be difficult to open or close. In most instances, a few minor repairs can transform these windows into smooth operation for the first time and save the homeowner cash on energy costs.

It is essential to have the tools you require before you begin. Start by marking the location of the hinge channel on the frame using pencil (Photo 1). This will allow you to position the channel in the right place when you are finished. Take the sash off and then remove all hardware including the parting beads, cords, and chains that help to hold the sash. Soften any putty that has been hardened with an electric heat gun set to medium and equipped with an shield for the nozzle. Remove the old sash and store it in an bag with a label.

Sash Weights

Sash weights can be changed to improve the performance of your window sash and decrease the energy cost. Sash weights consist of heavy iron or lead cylinders that are encased in a hidden cavity and attached by ropes to the moveable window sash. These weights act as counterbalances, allowing you to open and close the window without the need for mechanical or electrical devices. The sash weights are usually neglected or ignored by homeowners and then turned into scrap when they fail; therefore you might need to find replacements.

A sash weight that has fallen out of the cavity is difficult to get back, so you will want to locate a new one that is suitable for the. You will also need a new piece of string, a length of sash cord, and a few sash pulleys to connect the new sash weights to the sash cord.

Mortise and Tenon joints can be used to join older wood windows. Pin punch and hammer can be used to cut off the wood pegs that hold the components together. The majority of them are large on one side and smaller on the other. It is crucial to remove first the smaller diameter sides. Sashes that were made later in the century made use of glue instead of pegs and can be separated by cutting the glue line with an instrument, and then tapping the mortised area loose with mallets.

Once the sash is freed then you can take out the sash stop and access the weight pocket. This is typically done by drilling tiny holes in the bottom of each jamb. This hole is then covered by an access panel of wood that can be ripped off so that you can observe the inner workings of the frame.

When the sash has been shut off and the access panel is removed, you can take off the weight you used and replace it. Be sure to weigh the sash prior to you do this, as the weights that were previously used may be different sizes than what you require. After the new weight is installed, thread an appropriate length of string through the pulling mechanism. Then, you can attach the string to your boxed frame. Leave a few inches at the end of the string to allow future adjustments.

Sash Cords

In the majority of old double glazing near me-hung windows, a chain or cord is connected to the weights. This supports and keeps the sashes in the jamb balanced. Over time, these cords could break, making it difficult to raise the window. A new sash cable will give you the ability to raise and lower the sash, and keep it in position when opened.

The first step to replace sash cords is to locate and remove the access panels in the jambs. They are typically nailed or screwed in and will require to be removed or relocated. It is possible to take them out using the hammer or chisel but it is always best to lay out dust sheets before starting any work.

After removing the access panel, you are able to begin to work on the sash. Take the narrow beads (also called "tie rails") out of their grooves using flat bar or chisel. They are typically wedged into or nailed but can be prised free, so it's worth taking your time. If the sash remains in place, break the mortise and the tenon joints by using a hammer and pin punch or screwdriver, and then take out the wood pegs on each piece. It should now be possible to move the sash around without difficulty, though it will probably need some oiling if it seems stiff.

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

It is best to keep the original weights if you have purchased a kit that will replace the counterbalance that was previously installed. It's not expensive to buy them from architectural salvage stores and they'll be simple to install once you've got the sash open. Based on the size of your window, one or two sash weights might be required to keep it open.
