Window Sash Repairs

Window sashes must be inspected regularly for signs of mold, mildew, and damage. You can save future repair costs by catching the issues early on before they become out of control.

The sash is an inside frame that moves vertically up and down in windows that open. This article will show you how to do simple sash repairs.

Weather Stripping

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

The first step for sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. If it's loose or worn out, it can lead to drafts and other problems. To fix it, begin by determining your window doctor's brand and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Then, remove the sash and mark its height and width so that you can locate new weather stripping that matches.

Then, take it off and place it on a table to allow access to all four sides. If your sash has a double glazing repair-hung, you'll need to remove the weights as well as the ropes that go with them, which should have fallen into the pocket that was intended to be in the jamb liner. After removing the sash using the utility knife, take off the weather stripping that was left by hand or with a putty blade.

After the sash is cleared, you can replace the parting stops. These are long pieces that split the sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trimmings from the lumberyard. But, you can also use a scrap piece of wood.

After removing the parting stop and cutting it to length and then apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound with your putty tool and let it dry at least one day. When the putty is fully dried and dried, you can apply a topcoat of acrylic. This will help protect the putty and give your sash an updated appearance.

Sash Hardware

The hardware that holds the window sashes may wear out over time and with use. This could lead to a door or a window that is difficult to open or close. The good thing is that fixing and replacing this hardware is usually very simple and cost-effective. If a sash becomes difficult to operate try spraying grease into the jamb channel then open it to see if it solves the issue. If the issue continues it's likely the sash balance. It is necessary to remove the window sash to get access to this part of the hardware.

Window sashes should open and close without much effort. However, this could be a challenge if the weights have been worn out or the sash-to-rail connecting rail isn't coated. This can be due to many factors, including the lack 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 that's directly opposite the hinge arm (Photo 1). To address this problem, first ensure that the sash is squarely inserted into the frame's opening and then take it out of the window. If the sash is screwed onto the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

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

To make these repairs to the sash 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 pencil. This will allow you to get the channel back on the correct position after you've finished. Take the sash off, and remove all the hardware, including the parting beads, cords, and chains that keep the sash in place. Soften any hardened putty using an electric heat gun set to medium and fitted with a shield for the nozzle. Take off the old sash and put it in a bag with a label.

Sash Weights

Whether your window sash repairs are to replace a broken cord or simply to ensure that the windows are functional and functional, replacing worn-out weights on sash can improve sash operation and cut down on energy costs. Sash weights are composed of heavy lead or iron cylinders that are encased in a concealed cavity and are connected via ropes to the moveable window sash. They provide counterbalance that allows the window to be shut and opened without the use of electrical or mechanical devices. If they fail, sashweights are often ignored or disabled by homeowners.

It is difficult to recover a sash-weight that has fallen from the cavity, so you'll need to find one that is suitable for the. You will also need a new piece of string, a length sash cord, and a few sash pulleys to tie the new sash weights the sash cord.

Older wood windows are joined by mortise and tenon joints. Hammers and pins can be used to take out the wood pegs holding the components together. Most of these pegs have an enormous diameter on one side and a smaller one on the other, so it is essential to remove the smaller-diameter ones first. Later sashes made use of glue instead of pins. They can be cut with a knife and mallet.

Once the sash is freed, you can remove the sash stop and access the weight pocket. This is usually done via tiny holes in the bottom of each jamb. This hole is covered with a wooden panel that can be removed to reveal the inner workings.

After the sash has been stopped and the access panel has been removed, you can take off the weight that was previously installed and replace it. Be sure to weigh the sash before you begin, as the old weights could be different in size from what you require. After the new weight is installed, tie a string to it and thread it through the sash pulley. Then, you can nail the string to the frame, but only leave a few inches of string hanging from the head for future adjustments.

Sash Cords

In the majority of old double-hung windows the chain or cord is affixed to the weights. This keeps the sashes of the jamb balanced. As time passes, these cords may break, making it difficult to raise the window. A new sash cable can restore the ability to raise and lower the sash and keep it in 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. These are usually screwed or Window Doctor nailed into and need to be removed. You could employ a hammer and chisel to prise them off however, it is always best to lay down dust sheets prior to commencing any work.

After removing the access panel, you are able to begin to work on the sash. Make the small parting beads (also called "tie rails") out of their grooves using a chisel or flat bar. They are typically wedged into or nailed, but they can be prised free which is why it's worth your time. If the sash is still in place, pry the mortise and tenon joints free with a hammer or screwdriver and then remove each wood peg. It should now be possible to move the sash back and forth freely, though it might require oiling if it seems stiff.

Measure the length of the sash chain or sash cord needed to reach the sash slot on the bottom from the pulley located at the top of the jamb. Cut the cord or chain, and then fix it using Step 6 above. You can either employ a hammer, screws or nails, however nails are less likely to cause damage.

If you haven't purchased an item that replaces the counterbalance system that was in place before, it's best to keep the original weights for balancing in place. It's not too expensive to purchase them from architectural salvage stores and they will be easy to install once you have the sash opened. Depending on the dimensions and shape of your window you may require one or two sashweights to keep the sash open.
