Window Sash Repairs

Window sashes need to be checked regularly for mold, mildew, and damage. You can avoid future repair costs by catching the issues early on before they get out of hand.

The sash is the internal framing that moves vertically either up or down in windows that open. This article will show you how to do a variety of simple repairs to the sash.

Weather Stripping

Wooden window sashes are a great way to add an elegant appearance to your home. They are also durable and will last for many years when they are maintained properly. However, they can be damaged or degraded in time due to exposure to the elements and normal wear and tear. However, sash repair experts can restore your windows back to their original condition and maintain their appearance for much longer than newer replacement windows.

Weather stripping is the first issue to take care of when fixing windows with sash. It is located on both the frame and sash. If it's worn or loose, out, it can cause drafts, as well as other issues. Start by identifying the window brand and the date of manufacture for the glass (etched on the corner of the glass or the aluminum spacers between panes). Remove the sash and mark its width and height so that you can purchase replacement weather stripping that matches.

Then, remove the sash and place it on a table so you can access all four sides. If the sash is double-hung, you'll need to remove the weights and their ropes, which should have fallen into the pocket of the jamb liner. Once you've removed the sash using a utility knife, you can use it to cut off the weather stripping that was formerly in place at the corners. Then, take it off by hand or using a putty knife.

After the sash is cleared, you can install the stoppers that separate the two sashes. These are long pieces wood that are used to separate the two sashes. Pam prefers standard 1/2-inch by 3/4-inch window trim from the lumberyard. But, you can substitute with a scrap piece of wood.

After removing the stopper and cutting it to length and then apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using your putty knife, and allow it to dry for at least one day. After it has fully dried then apply a top coat of acrylic latex paint. This coating will protect the putty and give your sash a fresh appearance.

Sash Hardware

The hardware that holds the windows sashes can become worn out over time and 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 and fixing this hardware is usually simple and inexpensive. If you're having difficulty opening a sash spray some lubricant into the jamb channel. Then, slide the sash open to see if this resolves the problem. If the issue persists it's most likely that the sash balance is off. You'll need to remove the window sash to reach this hardware.

Window sashes should open and close without much effort. However, this could be difficult if the weights are worn out or the sash-to-rail meeting rail is not properly glazed. This problem can be caused by a number of things, such as insufficient maintenance or an incorrect weight rating for a particular sash.

If the hinge arms on windows begin to slide, this could cause the sash to drag, and then eventually to hit the frame at the opposite corner (Photo 1). To fix this issue, first make sure the sash is squarely inserted into the opening of the frame and then take it out of the window repairs near me. 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 deficiency in energy efficiency, old windows, especially those in older homes, can be difficult to open and close. In most instances, a few easy repairs can turn these windows into smooth operators again and save the homeowner money on energy costs.

To complete these sash repairs, it's important to have all of the tools needed before you begin. Start by marking the location of the hinge channel on the frame using pencil (Photo 1). This will make it easier to place the channel in the right place when you are finished. Then, remove the sash and take off the hardware, including the parting beads (Photo 2) and the chains or cords that hold it in place. A hot gun with nozzle shield and a medium setting can soften any putty that has been hardened. Take off the old sash and put it in a labelled bag.

Sash Weights

If your window sash repairs are to replace a broken cord or simply to keep the windows functional, replacing worn out weights for sash will improve its operation and help reduce energy consumption. Sash weights are heavy lead or iron cylinders enclosed in a concealed cavity and connected to the movable sash by rope. They provide counterbalance that allows the window to be shut 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 have to search for replacements.

A sash weight that has fallen 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 to the sash cord.

Mortise and Tenon joints can be used to join windows made of older wood. The wood pegs that hold the parts together can be removed with the use of a pin punch and hammer. The majority of them are large on one side and smaller on the other. It is essential to first remove the smaller diameter sides. Sashes made later in the century utilized glue instead of pegs and can be separated by cutting through the glue line with a knife, then tapping the mortised section loose using mallets.

Once the sash has been released, you can remove sash stops and gain access to the pockets for weights. This is usually done through an opening at the bottom of each jamb. This hole is covered by an access panel of wood that can be cut off to let you see the inner workings of the frame.

Once the sash is 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 do this, as the weights that were previously used may be different sizes than what you require. Once 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 boxed frame, but leave a few inches of string sticking out from the head to allow for future adjustments.

Sash Cords

Most double-hung windows of the past include a chain or cord attached to the weights which keeps the sashes level within the jamb. Over time, these cords could break, making it impossible to raise the window. A new sash cord can restore the ability to move the sash upwards and downwards and will keep it in its place when it is opened.

The first step to replace cords for sash is to locate and remove the access panels in the jambs. They are usually installed by screws or nails and will require to be removed or repositioned. You may be able to use a hammer or chisel to prise them off, but it's always better to lay down dust sheets before beginning any work.

After removing the access panel, you can begin working on the sash. Take the narrow beads (also known as "tie rails") out of their grooves with a chisel or flat bar. They are typically wedged into or nailed but can be removed, so it's worth taking your time here. If the sash remains in place, break the mortise and tenon joints using the help of a hammer and pin or screwdriver, then remove the wood pegs that are on the components. The sash should move freely, however it may need some lubrication in order to feel less stiff.

Measure the length of sash chain/sash cord required to reach the sash slot at the bottom, and the pulley at the top of the jamb. Cut the cord/chain and then attach it in Step 6 above. You can use a hammer, nails, or screws. However, nails are less likely than screws to cause damage.

It is recommended to keep the original weights if you have purchased a kit to replace the counterbalance that was previously installed. It's not expensive to buy these from salvage shops for architectural purposes and they'll be easy to install once you've got the sash open. Depending on the dimensions and shape of your window, you might need to install one or two sashweights to keep the sash open.
