Window Sash Repairs

window repair sashes need to be inspected regularly for signs of mold, mildew and damage. By catching problems before they become serious, you can save money on future repairs.

The sash is an internal frame that moves upwards and downwards in windows that open. This article will teach you how to do a variety of simple repairs to the sash.

Weather Stripping

Wooden window sashes can add an elegant look to your home. They are also sturdy and last for a long time if they are properly maintained. However, they can become damaged or deteriorate as time passes due to exposure to elements and normal wear and wear and tear. Sash repair specialists can restore windows back to their original condition and keep them looking great much longer than replacement windows.

The first step for sash window repairs is addressing weather stripping, which can be found on both the sash and frame. If it's damaged or worn out, it can cause drafts and other issues. Start by identifying the window brand and the manufacturer's date (etched on the corner of the glass or on the aluminum spacers between panes). Remove the sash and mark its width and height so you can find a new weather stripping that is compatible with the original.

Then, remove the sash from its holder, and place it on a flat surface to allow you to see all four sides. If your sash has a double-hung, you'll also need to remove the weights as well as their accompanying ropes, which should have fallen into the pocket of the jamb liner. After you've removed the sash, use a utility knife to remove the weather stripping from the corners, and then remove it manually or using a putty blade.

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

After removing the parting stops and trimming them to the desired length then apply a thin layer of glazing compound over the bottom of the sash. Smooth out the compound using your putty knife and let it dry for at least a day. Once it's fully cured, apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a new appearance.

Sash Hardware

The hardware that supports windows sashes can become worn out over time and use. This can result in windows or doors that is difficult to open or close. It's important to know that replacing and repair of this hardware is typically straightforward and cost-effective. If a sash becomes difficult to operate try spraying lubrication into the jamb channel then open it to see if this solves the issue. If not, the issue is likely to be with the sash balance and you'll need to take out the sash to access this hardware.

Ideally, window sashes must swing open and closed with minimal effort but this can be an issue if the weights become worn or if the sash that joins rail isn't properly coated. This issue can be caused by a number of reasons, such as the lack of maintenance or a mismatched weight rating for the particular sash.

If the hinge arms of a window begin to lose their elasticity, this could cause the sash's to drag and eventually hit the frame in the corner that's directly opposite the hinge arm (Photo 1). To fix the problem ensure that the sash is in the proper position within the frame opening, and then remove it. If the sash is screwed to the hinge arm, you'll have to remove the hinge arm and replace it (Photo 2). Install the new sash (Photo 3).

Old windows, especially those in older homes, may be difficult to close and open due to sagging hinges and an overall lack of energy efficiency. In many cases it is a matter of making a few minor adjustments that can allow these windows to operate smoothly again and save homeowners money on energy costs.

To make these repairs to the sash, it's important to have all of the necessary tools in place before you begin. Mark the hinge channel's location on the frame (Photo 1) with pencil. This will help you get the channel back into position correctly after you've completed. Remove the sash, and remove all the hardware including the parting beads, cords, and chains that help to hold the sash. A hot gun with nozzle shield and a medium setting will soften any hardened glue. Remove the old sash, and put it in a bag with a label.

Sash Weights

If your window sash repairs are to replace a damaged cord or just to keep your windows functioning, replacing worn out sash weights will improve sash operation and window repairs cut down on energy costs. Sash weights are hefty lead or iron cylinders that are enclosed inside a hidden compartment and connected to the movable the sash with a rope. These weights act as counterbalances and allow you to open and shut the window without having to use mechanical or electrical devices. When they fail, sashweights are often left unnoticed or disabled by homeowners.

It's not easy to retrieve an sash-weight which has fallen from the cavity, so you'll need to find one that fits correctly. You will also require a fresh piece of string, a length of sashcord and a few sashpulleys for tying the new weights to the cord.

Older windows made of wood are joined using mortise and tenon joints. The wood pegs that hold the parts together can be removed using 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 crucial to take out the smaller-diameter ones first. Later sashes used glue instead of pins. They can be separated by using a knife and mallet.

Once the sash is freed and removed, you can take off the stopper on the sash and get access to the weight pocket. Usually this is accomplished by drilling an opening at the bottom of each jamb. This hole is covered by an access panel of wood that can be ripped off so that you can see the inner workings of the frame.

When the sash has been shut off and the access panel has been removed, you can take off the weight you used and replace it. Make sure you weigh the sash prior to you do this, since the old weights may be different sizes than the one you need. Once the new weight is installed, you can thread a string through the sash pulling mechanism. Then, you can attach the string to the boxed frame. Leave a few inches protruding at the end of the string for future adjustments.

Sash Cords

In most old double-hung window repairs near me the chain or cord is affixed to the weights. This keeps the sashes within the jamb balanced. Over time these cords can break, making it impossible to raise the window. A new sash cable will give you 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 take out the access panels located in the jambs. They are usually installed by screws or nails and will need to be removed or moved. You might be able to use a hammer and chisel to remove them but it's best to lay down dust sheets prior to beginning any work.

After you have removed the access panel, you can begin to work on the sash. Take the narrow beads (also known as "tie rails") out of their grooves with flat bar or chisel. They are typically wedged into or nailed but can be removed and it's worth your time. If the sash is still in place, pry out the mortise and tenon joints with pin punch and hammer or screwdriver, then remove the wood pegs that are on the components. You should now be able to move the sash back and forth without difficulty, though it may require lubrication if it feels stiff.

With the sash in an open position Take a measurement of the sash chain to extend from the pulley on the top of the jamb to the sash slot on the bottom. Cut the chain or cord and attach it as described in the step 6 above. You can use a hammer, nails or screws. However nails are less likely than screws to cause damage.

It is best to keep the weights that came with the original counterbalance unless you have purchased a kit to replace the counterbalance that was previously installed. It's not too expensive 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 it open.
