Weather Stripping

Wood window sashes add an elegant look to your home. If properly maintained, they will last for many years. However, they may become damaged or degraded over time due to exposure to elements and wear and tear. Sash repair experts can restore windows to their original state and maintain their beauty much longer than replacement windows.

The first step to sash window repairs is addressing weather stripping, which can be found on both the sash as well as the frame. If it's worn or loose, out, it can lead to drafts, as well as other issues. To fix it, begin by determining your window's brand and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its width and height 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 see all four sides. If your sash is double-hung, you'll need to remove the weights as well as the ropes that go with them that should have fallen into the pocket that was intended to be in the jamb liner. After removing the sash with the utility knife, remove the weather stripping that was left by hand or with the putty blade.

After the sash has been cleared, you can replace the stoppers that separate the two sashes. These are long pieces of wood that are used to separate the two sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. However, you could also substitute with a scrap piece of wood.

After removing the stopper for the parting and trimming it to length, apply a thin coat of glazing compound on the bottom of the sash. Smooth it out using your putty knife, and then let it dry for at least a day. Once the putty has fully dried and dried, you can apply a topcoat of acrylic latex. This will protect the putty and give your sash a new appearance.

Sash Hardware

The hardware that holds the window sashes may wear out over time and use. This can result in the window or door that is difficult to open or close. It's good to know that replacing and repair of this hardware is typically easy and affordable. If a sash is difficult to operate, try spraying some lubrication into the jamb channel and then slide it open to see if that fixes the problem. If the issue continues, it is most likely to be due to the sash's balance. It is necessary to remove the window sash in order to get access to this part of the hardware.

The ideal situation is for window sashes to swing open and closed with minimal effort but this is a difficult task if the weights become worn or if the sash that joins rail isn't properly glazed. This issue can be due to various reasons that include an absence of maintenance or a mismatched weight rating.

If the hinges on a window begin to sag this could cause the sash to drag and then hit the frame at the opposite corner (Photo 1). To correct the issue ensure that the sash is in the proper position within the frame opening, and then take it off. If the sash has been screwed to the hinge arm, you'll have to remove the hinge arm and replace it (Photo 2). Then, you can install the new sash (Photo 3).

Because of sagging hinges and a general deficiency in energy efficiency, old windows particularly those in older homes, may be difficult to open or close. Many times it is a matter of making a few minor adjustments that can make these windows operate smoothly and help homeowners save money on their energy bills.

In order to make these sash repairs it is essential to have all of the necessary tools in place before you begin. Mark the hinge channel location on the frame (Photo 1) using a pencil. This will assist you in getting the channel back on the correct position after you've finished. Take the sash off and window sash repairs then remove all hardware including the parting beads cords, chains, and cords that keep 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 keep it in a labeled bag.

Sash Weights

Whether your window sash repairs are to replace a broken cord or simply to keep your windows functioning and functional, replacing worn-out weights on sash can improve sash operation and cut down on energy costs. Sash weights are composed of heavy iron or lead cylinders that are encased in a hidden cavity and attached by a rope to the movable window sash. They are counterbalancers which allows the window to be shut and opened without the need for mechanical or electrical devices. The sash weights are usually ignored or discarded by homeowners and then turned into scrap when they break; therefore, you may need to search for replacements.

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

Older wood windows are joined using mortise and tenon joints. The wood pegs holding the components together can be removed using pin punches and hammers. The majority of them are large on one side, but smaller on the other. It is important to remove first the smaller diameter sides. Later sashes made use of glue instead of pins. They can be cut by using a knife and mallet.

After the sash has been removed then you can take out the stopper on the sash and get access to the weight pocket. Usually, this is done through an opening in the bottom of each jamb. The hole is then covered with an access panel made of wood that can be cut off to let you view the inside of the frame.

Once you have the sash stopped and the access panel removed, you will be able to take off the old sash weight and replace it with new. First, weigh the sash, as the weights you have might not be the correct size. Once the new weight is installed, tie a string to it and then thread it through the pulley for the sash. Then, you can attach the string to the boxed frame. Leave a few inches at the end of the string to allow future adjustments.

Sash Cords

Most old double-hung windows include a chain or cord attached to the weights that keeps the sashes level within the jamb. Over time, these cords could break, making it impossible to raise the window. A new sash cord will restore the ability to move the sash up and down and keep it in place when opened.

To replace sash cords the first step is to remove the access panels from the jambs. These are usually nailed or screwed in and will need to be removed or moved. It may be possible to take them out using a hammer or chisel, but it is always better to lay out dust sheets prior to starting any work.

Once the access panel is removed, you can start working on the sash. Make the small parting beads (also called "tie rails") out of their grooves using the chisel or flat bar. It is essential to be patient, as these are often placed in a wedge or nail. If the sash remains in place, break the mortise and the tenon joints by using the help of a hammer and pin or screwdriver, then remove the wood pegs on each component. The sash should be able move freely now, but it might require some lubrication to feel less stiff.

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

It's best to leave the weights that came with the original counterbalance unless you have purchased a kit that will replace the counterbalance that was previously installed. It's not too expensive to purchase these from salvage shops for architectural purposes and they will be easy to install once you have the sash opened. Depending on the size of your window, one or two sash weights might be required to keep the sash in an open position.
