Window Sash Repairs

Regularly inspect the window sashes for signs of damage, mildew and mold. By catching problems before they become serious you can save money on future repairs.

The sash is the internal framing that can be moved vertically up or down in windows that open. This article will teach you how to perform simple sash repairs.

Weather Stripping

Wooden window sashes can add a classic look to your home. They are also sturdy and will last for many years provided they are properly maintained. However, they may become damaged or degrade in time due to exposure to elements and normal wear and tear. Thankfully, sash repair experts can restore your windows back to their original condition and keep them looking fantastic for much longer than newer replacement windows.

The first step to sash window repairs is addressing weather stripping, which is found on both the sash as well as the frame. It could cause drafts if damaged or is loose. Start by identifying the window's brand and the glass manufacturer's date (etched on the corner of the glass or on the aluminum spacers between panes). Then, take the sash off and mark its width and height, so you can find new weather stripping that matches.

Then, remove the sash and place it on a surface so you can access all four sides. If your sash was double-hung, you must remove the ropes and weights that should be buried in the jamb lining. After you've removed the sash, use a utility knife to remove the weather stripping from the corners, then take it off by hand or window repairs using a putty blade.

After the sash has been cleaned, you can replace the stoppers that separate the two sashes. These are long pieces that split the sashes. Pam prefers standard 1/2-inch by 3/4-inch window trim from the lumberyard. But, you can also use with a scrap piece of wood.

After removing the stoppers for parting and trimming them to the desired length then apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty knife, and then let it dry for at least a few days. When it's completely dried, apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that holds the windows sashes can become worn out with time and window repairs use. This could result in the window or door that is difficult to open or close. The good news is that repairing and replacing this hardware is typically quite simple and inexpensive. If a sash is difficult to operate you can try spraying some lubrication into the jamb channel and then open it to see if it solves the issue. If the issue continues, it is most likely the sash balance. You'll need to take off the window sash in order to get access to this part of the hardware.

Window sashes should open and close with little effort. However, this could be difficult if weights are worn out or the sash-to-rail connecting rail isn't covered with. This issue could be caused by a variety of reasons, such as lack of maintenance or by the wrong weight rating for the particular window sash.

If the hinge arms on a window begin to sag this could cause the sash to drag and eventually hit against the frame at the opposite corner (Photo 1). To fix the problem ensure that the sash is in the proper position within the frame's opening and remove it. 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, especially those in older homes, can be difficult to open and close, due to hinges that are sagging and a general lack of energy efficiency. Many times just a few easy fixes can make these windows operate smoothly and help homeowners save money on their energy bills.

To complete these repairs to the sash it is essential to have all of the tools needed before you begin. Begin by marking the location of the hinge channel on the frame with pencil (Photo 1). This will assist you in getting the channel back in position correctly after you've completed. Remove the sash and take out all the hardware, including the parting beads, cords, and chains that help to hold the sash. Soften any hardened putty using an electric heat gun set to medium and fitted with an nozzle shield. Remove the old sash, and place it in a bag with a label.

Sash Weights

No matter if your window sash repair needs are to replace a broken cord or simply to ensure that the windows are functional by replacing worn out weights for sash will improve its operation and reduce energy costs. Sash weights are composed of heavy iron or lead cylindricals that are contained in a concealed cavity and connected by ropes to the moveable window sash. They are counterbalancers which allows the window to be closed and opened without the need for mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners and then turned into scrap when they fail; therefore, you may need to search for replacements.

A weight in a sash that has fallen out of the cavity is difficult to recover It is therefore important to find a new one that fits properly. You will also require a new piece of string, a length of sash cord and some sash pulleys that will tie the new sash weights the sash cord.

Mortise and Tenon joints can be used to join older wood windows. Pin punch and hammer can be used to cut off the wood pegs holding the components together. The majority of these pegs are large on one side, and smaller on the other. It is crucial to remove first the smaller diameter sides. Later sashes made use of glue instead of pins. They can be separated with a knife and mallet.

After the sash is released, you can remove the stops on the sash and get access to the pockets for weights. This is typically done by drilling a small hole at the bottom of each jamb. The hole is then covered with an access panel made of wood that can be ripped off to let you observe the inner workings of the frame.

After the sash has been stopped and the access panel removed, you will be able to take off the weight from the sash and replace it with the new. Weigh the sash first, as the weights you have might not be of the right size. Once the new weight is in place then tie a string to it and thread it through the pulley for the sash. Then, attach the string to the boxed frame. Leave a few inches at the head of the string to allow for future adjustments.

Sash Cords

Most double glazing repairs-hung windows of the past come with a chain or cord attached to the weights which supports and keeps the sashes in balance within the jamb. Over time, these cords could break, making it difficult to raise the window. A new sash cord will restore the ability to move the sash upwards and downwards and keep it in place when opened.

The first step in replacing cords for sash is to locate and remove the access panels in the jambs. These are usually nailed or screwed in and will need to be removed or repositioned. It is possible to remove them with an axe or hammer, but it is always better to lay out dust sheets before beginning any work.

After the access panel has been removed, you can begin working on the sash. Take the narrow beads (also known as "tie rails") out of their grooves using the chisel or flat bar. They are usually wedged in or nailed but can be removed which is why it's worth your time here. 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. You should be able to move the sash around freely, although it might require lubrication if it feels stiff.

With the sash open With the sash in an open position, measure the sash chain or cord to reach from the pulley in the top of the jamb to the sash slot in the bottom. Cut the cord/chain and then secure it as in the previous step. You can use either nail, hammer or screws. However nails are less likely than screws to cause damage.

If you haven't purchased a kit that replaces the old counterbalance system, it's recommended to keep the original weights for balancing in place. It's cheap to purchase these from salvage shops for architectural purposes and they'll be easy to install once you've got the sash opened. Based on the size of your window, two or three sash weights may be needed to keep it open.
