Window Sash Repairs

Sashes for windows must be inspected regularly for signs of mold, mildew, and damage. By catching problems before they become serious you will save money on future repairs.

The sash is the internal framing that moves vertically either up or down in windows that open. This article will show you how to perform easy repairs to your sash.

Weather Stripping

Wood window sashes add the classic look to your home. When properly maintained, can last for a long time. However, they may become damaged or deteriorate as time passes due to exposure to elements and wear and tear. Sash repair specialists can restore windows back to their original condition and maintain their beauty much longer than replacement windows.

Weather stripping is the first issue to take care of when fixing windows with sash. It's located on both the frame and the sash. It could cause drafts if damaged or is loose. Begin by identifying the brand of window and the manufacturer's date (etched on the glass's corner or on the aluminum spacers between panes). Remove the sash and mark its size and width so that you can find a new weather stripping that is compatible with the original.

Then, remove 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 have to remove the weights as well as the ropes that go with them which should have slipped into the intended pocket in the jamb liner. Once you've taken the sash off using a utility knife, you can use it to cut away the weather stripping from the corners, and then remove it manually or with a putty knife.

Once the sash has been cleaned, you can replace parting stops. These are long pieces that divide the sashes. Pam likes to replace them 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 and cutting it to length after which, apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound with your putty knife, and then let it dry for at least a few days. Once it's fully cured, apply a top coat of acrylic latex paint. This will protect the putty, and give your sash a modern look.

Sash Hardware

The hardware that supports window sashes can wear out with time and use. This can result in windows or doors 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 you're having trouble opening a sash spray some oil into the jamb channel. Then slide the sash open to see if this resolves the issue. If not, the issue is most likely due to the sash balance, and you'll need to take out the sash to gain access to the hardware.

Ideally, window sashes should be able to open and close with very little effort, but this can be an issue when the weights wear out or if the sash's meeting rail isn't properly coated. This problem can be caused by a number of things, such as the lack of maintenance or a mismatched weight rating for the particular sash.

If the hinge arms on a window begin to sag this can cause the sash drag, and then eventually to hit the frame in the opposite corner (Photo 1). To correct the issue make sure the sash is aligned in the frame opening and then remove it. If the sash is fixed to the hinge arm, unbolt the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).

Due to hinges that are sagging, and a general lack in energy efficiency, windows that are old particularly those in older homes, can be difficult to open and close. Many times just a few easy fixes can help these windows function smoothly again and help homeowners save money on their energy bills.

It is crucial to have the tools you require before you begin. Mark the location of the hinge channel on the frame (Photo 1) using a pencil. This will help you get the channel back in position correctly after you've completed. Take the sash off, and remove all the hardware including the parting beads cords, chains, and cords that keep the sash in place. Soften any hardened putty using a heat gun set to medium and fitted with a nozzle shield. Take off the old sash and place it in a labelled bag.


Sash Weights

Sash weights are able to be replaced to improve the performance of your window sash and reduce the energy cost. Sash weights are heavy lead or iron cylinders that are enclosed in a hidden cavity and linked to the moveable the sash with rope. These weights act as counterbalances, allowing you to open and close the window without having to use mechanical or electrical devices. The sash weights are often disregarded or disabled by homeowners, and are turned into scrap when they fail; therefore you might need to find replacements.

A weight from a sash that fell out of the cavity is difficult to get back It is therefore important to find a replacement that fits properly. You will also require a fresh piece of string, a length sashcord and a few sashpulleys to secure the new weights to the cord.

Mortise and Tenon joints are used to join older wood windows. The wood pegs that hold the components together can be removed using the use of a pin punch and hammer. Most of them have a large diameter on one side and a smaller one on the other, which is why it is essential to remove the smaller-diameter sides first. Later sashes utilized glue instead of pins. They can be cut with a knife and mallet.

Once the sash has been removed, you can take off the stops on the sash and get access to the weight pockets. Usually, this is done through an opening at the bottom of each jamb. The hole is surrounded by the wooden panel which can be removed to reveal the interior workings.

After the sash has been stopped and the access panel is removed, you can remove the old weight and replace it. First, weigh window repairs Hackney because the weights you've got may not be the correct size. Once the new weight is installed, run a string through the sash pulling mechanism. Then attach the string to the frame, but only leave a few inches of string protruding from the head for future adjustment.

Sash Cords

The majority of double-hung windows with a history come with a chain or cord attached to the weights that supports and keeps the sashes in balance in the jamb. Over time, these chains may become damaged and make it difficult to raise the windows. A new sash cable will restore the ability to move and lower the sash and keep it in position when opened.

The first step in replacing sash cords is to locate and remove the access panels within the jambs. They are typically fixed or screwed in and will need to be removed or relocated. It may be possible to remove them using a hammer or chisel, but it is always better to lay out dust sheets before beginning any work.

After removing the access panel, you can begin working on the sash. Prise the narrow parting beads (also known as "tie rails") out of their grooves with the chisel or flat bar. It's important to take your time, as these are often placed in a wedge or nail. If the sash is in place, remove the mortise and tenon joints using a hammer and pin punch or screwdriver, then unhook the wood pegs on each piece. The sash should be able to move around freely now, however it might require some lubrication in order to feel less stiff.

Measure the length of sash cord/chain required to reach the sash slot at the bottom of the pulley on the top of the jamb. Cut the cord or chain and secure it as in the previous step. You can employ a hammer and screws or nails, however nails are less likely to cause damage.

It is best to keep the original weights if you've purchased a kit to replace the counterbalance that was previously installed. They're not expensive and simple to install if you buy them at architectural salvage stores. Based on the size and shape of your window, you might need to install one or two sashweights to keep the sash open.
