Window Sash Repairs

Window sashes must be checked regularly for mold, mildew, and damage. By catching problems before they become serious, you can save money on repairs in the future.

The sash is an inside frame that can move up and down vertically in windows that are open. This article will show you how to carry out a few simple repairs to sash.

Weather Stripping

Wood window sashes add an elegant look 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 and tear. Sash repair specialists can restore windows to their original condition and maintain their appearance much longer than replacement windows.

The first step to sash window repairs is addressing weather stripping. It's found on both the sash and frame. It could cause drafts if damaged or is loose. To fix it, start by finding your window 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, remove the sash and mark its height and width to find the appropriate weather stripping replacement to match.

Then, you can remove the sash from its holder and place it on an even surface that allows you to see all four sides. If your sash has a double-hung, you'll 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 and the weights, use a utility knife to cut off the weather stripping from the corners, then remove it by hand or using a putty blade.

After the sash has been cleared, you can replace parting stops. These are long pieces of wood that divide the two sashes. Pam prefers to use the standard 1/2-inch by 3/4-inch window trimmings from the lumberyard. But, you can substitute for a scrap piece of lumber.

After removing the parting stop and cutting it to length after which, apply a thin layer of glazing compound on the bottom of the sash. Smooth it out using your putty knife and let it dry for window repairs at least a day. When the putty is fully dried it is possible to apply a topcoat of acrylic latex. This coating will protect the putty and give your sash a fresh appearance.

Sash Hardware

The hardware that supports the window sashes can wear out over time and with use. This can result in a upvc door repairs near me or a window that is difficult to open or close. The good news is that fixing and replacing this hardware is usually relatively easy and affordable. If you're having trouble opening a sash spray some lubricant into the jamb channel. Then slide the sash up and open to see if this resolves 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 reach this hardware.

Ideally, window sashes must be able to open and close with very little effort, but this can be difficult if the weights become worn or if the sash's meeting rail isn't properly coated. This issue can be caused by a variety of things, such as the lack of maintenance or the wrong weight rating for a particular sash.

If the hinges on the window begin to move, this can cause the sash drag, and then eventually to hit the frame at the opposite corner (Photo 1). To resolve this issue, first make sure the sash fits squarely in the opening of the frame and then remove it from the window. If the sash has been fixed to the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash (Photo 3).

Old windows, particularly those in older houses, can be difficult to close and open due to sagging hinges and a general inefficiency. In many cases, a few simple fixes can help these windows function smoothly once more and help homeowners save money on energy costs.

It is essential to have the tools needed before you start. Begin by marking the location of the hinge channel on the frame with a pencil (Photo 1). This will assist you in getting the channel back on the correct position after you've finished. Remove the sash and then remove all hardware, including the beads for parting cords, chains, and cords that hold the sash in place. A hot gun with nozzle shield and a medium setting can soften any hardened putty. Remove the old sash, and keep it in a bag labeled.

Sash Weights

Whether your window sash repairs are to replace a broken cord or to keep your windows functioning by replacing worn out sash weights will improve sash operation and cut down on energy costs. Sash weights are composed of iron or lead cylinders that are encased in a concealed cavity and connected by ropes to the movable window sash. They are counterbalancers that allows the window to be shut and opened without the need for mechanical or electrical devices. The sash weights are often disregarded or disabled by homeowners and then turned into scrap when they break; therefore you might need to find replacements.

A weight from a sash that fell out of the cavity is difficult to get back and you'll need to locate a new one that fits correctly. You will also require a new piece of string, a length of the sash cord, as well as some sash pulleys that will tie the new sash weights the sash cord.

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

Once the sash has been removed, you can take off the stops on the sash and get access to the weight pockets. This is usually done via tiny holes at the bottom of every jamb. This hole is covered with a wooden panel that can be removed to reveal the inside workings.

After you have the sash stopped and the access panel removed, you'll be able to remove the weight from the sash and window repairs replace it with new. Make sure you weigh the sash before you begin, as the old weights may be different in size from what you require. Once the new weight is installed, you can thread a string through the sash pulling mechanism. Then attach the string to the boxed frame, leaving a few inches of string sticking out from the head for future adjustments.

Sash Cords

Most old double-hung windows have a cord or chain attached to the weights that supports and keeps the sashes level within the jamb. Over time, these cords could 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 position when opened.

To replace sash cords the first step is to remove the access panels from the jambs. They are typically screwed or nailed in and need to be removed. You could use a hammer and chisel to prise them off, but it's always better to lay down dust sheets before starting any work.

After removing the access panel, you are able to begin working on the sash. Make the small parting beads (also called "tie rails") out of their grooves using a chisel or flat bar. It's important to take your time as they're often placed in a wedge or nail. If the sash remains in place, break the mortise and tenon joints with the help of a hammer and pin or screwdriver, and then take out the wood pegs attached to the components. You should now be able to move the sash around freely, although it will probably need some lubrication if it feels stiff.

Determine the length of sash chain/sash cord required to reach the sash slot at the bottom of the pulley at the top of the jamb. Cut the cord/chain and then attach it in the previous step. You can use either nail, hammer or screws. However, nails are less likely than screws to cause damage.

If you don't have an upgrade kit to replace the old counterbalance system it's recommended to keep the original balancing weights in place. They're not expensive and simple to install if purchased them from architectural salvage stores. Based on the size of your window, one or two sash weights may be needed to keep the sash in an open position.
