Window Sash Repairs

Window sashes must be regularly checked for mold, mildew, and damage. You can save future repair costs by catching problems early before they become too much.

The sash is an internal frame that is able to move upwards and downwards in windows that are open. This article will teach you how to do simple repairs to sash.

Weather Stripping

Wood window sashes add a classic aesthetic to your home and, when properly maintained, they can last for a long time. However, they may become damaged or deteriorate over time due to exposure to the elements and normal wear and wear and tear. Sash repair experts can restore windows back to their original condition and maintain their appearance much longer than replacement windows.

The first step for repair sash window damage is to fix weather stripping, which is found on both the sash as well as the frame. If it's worn or loose, out, it can cause drafts and other issues. Begin 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). Take the sash off, and mark its size and width so that you can purchase new weather stripping that is compatible with the original.

Then, remove the sash from the holder and place it on flat surfaces to allow you to reach all four sides. If your sash is double-hung, you'll have to remove the weights and their ropes, which should have fallen into the pocket of the jamb liner. After you've removed the sash, use a utility knife to cut off the weather stripping that was formerly in place at the corners, and then remove it by hand or with a putty knife.

Once the sash is clear it is time to replace the parting stops. These are long pieces wood that divide the two sashes. Pam likes to replace these with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard, but you could also use scrap wood.

After removing the stopper for the parting and cutting it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound with your putty knife, then let it dry for at least a day. After the putty has completely dried it is possible to apply an acrylic latex topcoat. This will protect the putty, and give your sash an updated look.

Sash Hardware

The hardware that supports the windows sashes can become worn out over time and with use. This could lead to the window or door that is difficult to open or close. It's a good idea to know that replacing or repair of this hardware is typically easy and affordable. If a sash isn't easy to operate, try spraying some grease into the jamb channel then open it to see if this solves the issue. If not, the problem is likely to be with the sash balance and you'll have to take off the sash to gain access to this hardware.

The ideal situation is for window sashes to swing open and closed with very little effort, but this can be difficult when the weights wear out or if the sash meeting rail isn't properly glazed. This issue could be caused by various reasons such as an absence of maintenance or an unmatched weight rating.

If the hinge arms on a window begin to sag this can cause the sash drag and then hit the frame at the opposite corner (Photo 1). To fix this problem, first ensure that the sash is squarely inserted into the opening of the frame and then take it out of the window doctor near me. If the sash is screwed to the hinge arm, you'll need to remove the hinge arm and replace it (Photo 2). Then, you can install the new sash (Photo 3).

Due to hinges that are sagging, and a general lack of energy efficiency, older windows especially in older homes, can be difficult to open or close. In most instances, a few minor repairs can transform these windows into smooth operators again and save the homeowner cash on energy costs.

To make these repairs to sash, it's important to have all the necessary tools lined up before you begin. Begin by marking the location of the hinge channel on the frame with a pencil (Photo 1). This will help you get the channel back in place correctly when you're finished. Remove the sash and take off the hardware including the beads that separate (Photo 2) and the chains or cords that secure it. Heat gun with nozzle shield and medium setting will soften any putty that has been hardened. Remove the old sash and place it in a bag with a label.

Sash Weights

If your window sash repairs are to replace a damaged cord or simply to keep your windows functioning and functional, replacing worn-out weights for sash will improve its operation and cut down on the energy cost. Sash weights are heavy, lead or iron cylinders, which are enclosed in a hidden cavity and attached to the movable sash by rope. These weights provide counterbalance which allows the window to be shut and opened without using mechanical or electrical devices. The sash-weights are typically disregarded or disabled by homeowners and turned into scrap when they fail; therefore you may have to locate replacements.

A weight in a sash that has fallen out of the cavity is difficult to recover and you'll need to find a new one that is suitable for the. You will also require a new piece string, a length of sashcord and a few sashpulleys for tying the new weights to the cord.

Older windows made of wood are joined with mortise and tenon joints. Hammers and pins can be used to cut off the wood pegs that hold the parts together. The majority of them have an enormous diameter on one side and a smaller one on the other, which is why it is essential to remove the small-diameter sides first. Sashes that were made later in the century used glue instead of pegs and can be separated by cutting through the glue line with the help of a knife, and then tapping the mortised area loose with mallets.

After the sash is released, you can remove the sash stops and gain access to the weight pockets. Usually, this is done through an opening at the bottom of each jamb. This hole is then covered by an access panel made of wood which can be removed so that you can view the inside of the frame.

After you have the sash stopped and the access panel removed, you will be able to remove the old sash weight and replace it with new. Be sure to weigh the sash before you begin, as the old weights may be a different size than what is needed. After the new weight is in place you can tie a string around it and thread it through the pulley of the sash. Then, nail the string to the boxed frame. Leave a few inches protruding at the end of the string to allow future adjustments.

Sash Cords

The majority of double-hung windows with a history have a cord or chain attached to the weights that keeps the sashes balanced in the jamb. Over time, these cords can become damaged and make it impossible to raise the windows. A new sash cable will restore the ability to raise and lower the sash and keep it in place when it is opened.

The first step in replacing sash cords is to locate and remove the access panels in the jambs. They are usually fixed or screwed in and will require to be removed or relocated. It may be possible to take them out using an axe or hammer, but it is always better to lay out dust sheets prior to beginning any work.

After the access panel has been removed, you can start 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 in, but they can be prised free and it's worth your time. If the sash is still in place, pull the mortise and tenon joints free with a hammer or screwdriver, then remove each wood peg. The sash should be able to move freely, however it might require some lubrication in order to feel less stiff.

Measure the length of sash cord/chain needed to reach the sash slot at the bottom from the pulley located at the top of the jamb. Cut the cord or chain and fix it as described in Step 6 above. You can use a hammer and screws or nails, but nails are less likely to cause damage.

If you haven't purchased an upgrade kit to replace the counterbalance system that was in place before, it is recommended to keep the original weights for balancing in place. They're not expensive and simple to install if you purchase them from architectural salvage stores. Based on the size and shape of your window, you may need to use one or two sashweights in order to keep the sash open.
