Window Sash Repairs

Make sure to check the sashes of your windows regularly for any damage, mildew and mold. You can reduce the cost of repairs in the future by catching problems early before they become out of control.

The sash is an interior frame that moves vertically up and down in windows that open. This article will teach you how to make several simple sash repairs.

Weather Stripping

Wood window sashes add an elegant look to your home and, when properly maintained, can last for years. However, they may become damaged or degraded as time passes due to exposure to elements and wear and wear and tear. Sash repair specialists can restore windows to their original condition and maintain their beauty much longer than 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 can cause drafts if worn out or loose. To fix it, start by determining your window repair's brand and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Then, remove the sash and mark its height and width to find replacement weather stripping to match.

Then, remove the sash from its holder, and place it on a flat surface to allow you to access all four sides. If your sash was double-hung, remove the weights with their ropes that should have fallen into the pocket within the jamb lining. Once you've removed the sash, use a utility knife to remove the weather stripping from the corners, and then remove it manually or 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 divide the sashes. Pam prefers to replace them with standard 1/2-inch-by - 3/4-inch window trim from the lumberyard. However, you could also use a piece of scrap wood.

After removing the stoppers for parting and cutting them to the desired length and thickness, apply a thin layer of glazing compound over the bottom of the sash. Smooth it out using your putty knife and let it dry for a minimum of a day. When it's completely dried then apply a top coat of acrylic latex paint. This will protect the putty and give your sash a fresh appearance.

Sash Hardware

The hardware that supports the window sashes may wear out with time and use. This could result in windows or doors that is difficult to open or close. The good thing is that fixing and replacing this hardware is usually relatively easy and affordable. If you're having difficulty opening a sash spray some oil into the jamb channel. Then slide the sash open to see if this resolves the problem. If not, the problem is likely with the sash balance and you'll need to take out the sash in order to access this hardware.

Sashes for windows should be able to open and close without much effort. However, this can be difficult if the weights are worn out or the sash connecting rail isn't properly glazed. This issue can be caused by a variety of reasons, such as the lack of maintenance or the wrong weight rating for the specific window sash.

If the hinge arms of a window begin to slide, this could cause the sash's to drag and eventually hit the frame in the corner opposite the hinge arm (Photo 1). To fix this problem, first ensure that the sash fits squarely in the frame's opening and then take it out of the window. If the sash is secured to the hinge arm, you'll have to remove the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).

Due to sagging hinges, and a general lack in energy efficiency, old windows, especially those in older homes, can be difficult to open or close. In many instances, a few minor repairs can transform these windows into smooth operation and save homeowners cash on energy costs.

To complete these sash repairs, it's important to have all the tools needed before you begin. Begin by marking the position of the hinge channel on the frame using pencil (Photo 1). This will help you get the channel back in position correctly after you've completed. Then, remove the sash and take off the hardware, including the parting beads (Photo 2) and the cords or chains that secure it. Heat gun with nozzle shield and a medium setting can soften any putty that has been hardened. Remove the old sash and store it in a bag labeled.

Sash Weights

Whether your window sash repairs are to replace a broken cord or to ensure that the windows are functional by replacing worn out sash weights will improve sash operation and cut down on energy consumption. Sash weights are heavy, lead or iron cylinders, which are enclosed in a hidden cavity and linked to the moveable sash by a rope. These weights provide counterbalance which allows the window to be shut and opened without using mechanical or electrical devices. If they fail, sashweights are often left unnoticed or disabled by homeowners.

It is difficult to recover an sash-weight which has fallen from the cavity, so you'll want to find one that is suitable for the. You will also require a new piece of string, a length of sashcord and a few sashpulleys to secure the weights you are replacing to the cord.

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

After the sash is removed, you can take off the sash stops and gain access to the pockets for weights. Usually, this is done through a hole near the bottom of each jamb. This hole is covered by an access panel of wood which can be removed to let you view the inside of the frame.

After the sash has been stopped and the access panel removed, you will be able to remove the old sash weight and replace it with new. Weigh the sash first because the weights you've got may not be of the right size. Once the new weight is installed, run the string through the sash pulling mechanism. Then, nail the string to the boxed frame. Leave a few inches of space at the head of the string to allow future adjustments.

Sash Cords

Most old double-hung windows come with a chain or cord attached to the weights which keeps the sashes in balance 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 up and down and will keep it in its position when it is opened.

To replace sash cords the first step is to remove the access panels from the jambs. These are usually nailed or screwed in and will need to be removed or moved. You might be able to use a hammer or chisel to prise them off but it's best to lay down dust sheets before beginning any work.

After you have removed the access panel, you are able to begin working on the sash. Use a flat bar or chisel to pry the narrow parting beads out of their grooves. These are often wedged in or nailed but can be snipped out and it's worth your time here. If the sash is still in place, pull the mortise-and-tenon joints out with a screwdriver or hammer and then take out each wood peg. It should now be possible to move the sash around freely, though it might require oiling if it seems stiff.

With the sash in an open position With the sash in an open position, measure the sash chain or cord to extend from the pulley on the top of the jamb to the sash slot at the bottom. Cut the cord/chain, and then fix it using Step 6 above. You can either employ a hammer, nail or screws, but nails are less likely to cause damage.

It's best to leave the weights that came with the original counterbalance unless you've purchased a kit to replace the counterbalance that was previously installed. They are not expensive and are easy to install if you buy them at architectural salvage stores. Depending on the dimensions and shape of your window, you may require one or two sashweights in order to keep the sash open.
