Window Sash Repairs

Check the windows sashes regularly for any damage, mildew and mold. If you catch these issues early you can save money on repairs in the future.

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

Weather Stripping

Wood window sashes add a classic aesthetic to your home. When properly maintained, they can last for many years. They may, however, become damaged or degraded with time due to exposure and normal wear. Sash repair experts can restore windows back to their original condition and keep them looking great longer than replacement windows.

The first step in sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. If it's damaged or worn out, it could cause drafts and other problems. Begin by identifying the window's brand and the glass manufacturer's date (etched on the glass's corner or on the aluminum spacers between panes). Then, remove the sash and mark its height and width to find new weather stripping that matches.

Then, take the sash from its holder, and place it on a flat surface to allow you to access all four sides. If the sash is double-hung, you'll need to remove the weights and the ropes that go with them, 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, then remove it manually or using a putty blade.

After the sash has been cleared and clean, you can put in the parting stops. They are long pieces of wood that divide the two sashes. Pam likes to replace them with standard 1/2-inch-by 3/4-inch window trim from the lumberyard, however you can also replace them with scrap wood.

After removing the parting stop and cutting it to length, apply a thin coat of glazing compound on the bottom of the sash. Smooth the compound with your putty knife, and let it dry for at least one day. When the putty is fully dried, you can apply a topcoat of acrylic. This coating will protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that supports window sashes susceptible to wear and tear from time and usage and the result could be a window or door that isn't able to open or close easily. It's a good idea to know that replacing or repair of this hardware is typically straightforward and cost-effective. If a sash isn't easy to operate try spraying oil into the jamb channel, and Window Repair then open it to see if this resolves the issue. If the problem persists it's likely that the sash balance is off. It is necessary to remove the window sash in order to access the hardware.

Ideally, window sashes should move open and shut without effort, however, this can be a difficult task when the weights wear out or if the sash meeting rail isn't properly glazed. This issue can be due to a variety of factors that include an absence of maintenance or a mismatched weight rating.

If the hinge arms of a window are beginning to sag, this can cause the sash to slide and eventually strike the frame in the corner directly opposite the hinge arm (Photo 1). To fix this issue, first make sure the sash is squarely inserted into the frame's opening and window repair then remove it from the window. If the sash is fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Old windows, especially those in older houses, can be difficult to close and open due to sagging hinges and general inefficiency. In many cases just a few easy fixes can allow these windows to operate smoothly and save homeowners money on energy costs.

It is crucial to have the tools you require before you begin. Mark the hinge channel's location on the frame (Photo 1) with pencil. This will allow you to place the channel in the right position after you've finished. Take the sash off and then remove all hardware including the parting beads, cords, and chains that hold the sash in place. Soften any hardened putty using the help of a heat gun set at medium and fitted with a nozzle shield. Remove the old sash, and place it in a labelled bag.

Sash Weights

Sash weights are able to be replaced to enhance the efficiency of your window sash and decrease the cost of energy. Sash weights are heavy lead or iron cylinders enclosed in a concealed cavity and linked to the moveable sash by a rope. They are counterbalancers, allowing the Window Repair to be opened and closed without the need for mechanical or electrical devices. When they fail, sashweights are often ignored or disabled by homeowners.

It's difficult to retrieve the sash-weight that fell 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 some sashpulleys to tie the new weights to the cord.

Older windows made of wood are joined by mortise and tenon joints. The wood pegs holding the parts together can be removed using the use of a pin punch and hammer. The majority of them have a large diameter on one side and a smaller size on the other, so it is crucial to take out the small-diameter sides first. Later sashes used glue instead of pins. They can be cut with a knife and mallets.

After the sash is released, you can remove sash stops and gain access to the weight pockets. This is typically done by drilling an opening at the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the inside workings.

Once the sash is stopped and the access panel is removed, you are able to remove the weight you used and replace it. Be sure to weigh the sash first, as the weights you have may not be of the right size. Once the new weight is installed, you can thread an appropriate length of string through the pulling mechanism. Then nail the string to the frame, but only leave a few inches of string sticking out from the head for future adjustments.

Sash Cords

Most double-hung windows of the past come with a chain or cord connected to the weights that keeps the sashes balanced within the jamb. Over time, these chains can become damaged and make it impossible to raise the windows. A new sash cord can restore the ability to move the sash up and down and will keep it in its position when it is opened.

The first step in replacing cords for sash is to locate and take out the access panels located in the jambs. They are typically attached by nails or screws and require removal. It may be possible to remove them using the hammer or chisel but it is always best to lay out dust sheets before starting any work.

After you have removed the access panel, you can begin working on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves using a chisel or flat bar. It's important to be patient because they are usually wedged or nailed in place. If the sash remains in place, break the mortise and tenon joints using a hammer and pin punch or screwdriver, then remove the wood pegs that are on the components. The sash should move freely now, but it might require some lubrication to feel less stiff.

Take a measurement of 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/chain and then attach it in Step 6 above. You can do this with a hammer, nails or screws. However, nails are less likely to cause damage.

It is best to keep the original weights if you've purchased a kit that will replace the counterbalance that was previously installed. It's not too expensive to purchase them from architectural salvage stores and they'll be simple to install once you've got the sash open. Depending on the size of your window, one or two sashweights may be needed to keep it in an open position.
