The first step in sash window repairs is addressing weather stripping, which can be found on both the sash as well as the frame. If it's loose or worn out, it can lead to drafts and other problems. To fix it, start by determining your window's brand and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Remove the sash and mark its width and height so you can get new weather stripping that is compatible with the original.

Then, you can remove the sash from its holder, and place it on flat surfaces to allow you to reach all four sides. If your sash has been double-hung, you must remove the ropes and weights that should be buried within the jamb lining. After removing the sash using the utility knife, remove the weather stripping that was left by hand or using the putty blade.

After the sash has been cleared, you can install parting stops. These are long pieces that divide the sashes. Pam prefers the standard 1/2-inch by 3/4 inch window trim from the lumberyard. However, you can also use with a scrap piece of wood.

After removing the stoppers for parting and trimming them to your desired length and thickness, apply a thin layer of glazing compound to the bottom of the sash. Smooth it out using your putty knife and let it dry for a minimum of a day. Once it's fully cured, 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 supports window sashes prone to wearing out from the wear and tear of use, and the result can be a window or door that won't open or close easily. The good news is that fixing and replacing this hardware is typically relatively easy and affordable. If you are having trouble opening the sash, spray some lubricant into the jamb channel. Then, you can slide the sash up and open to see if this resolves the problem. If not, the issue is likely with the balance of the sash 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 may be difficult if the weights are worn out or the sash-to-rail connecting rail isn't properly covered with. This issue can be caused by a number of things, such as the lack of maintenance or an incorrect weight rating for the specific window sash.

If the hinge arms of a window begin to lose their elasticity, this could cause the sash to drag and eventually hit the frame in the corner that's opposite the hinge arm (Photo 1). To correct the issue ensure that the sash is aligned in the frame opening, and then take it off. If the sash is secured to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).

Windows that are old, especially in older homes, can be difficult to open and close due to hinges that are sagging and general inefficiency. In most instances, a few minor repairs can transform these windows into smooth operation and save homeowners money on energy costs.

It is essential to have the tools needed before you begin. Begin by marking the location of the hinge channel on the frame using pencil (Photo 1). This will make it easier to put the channel in the right position after you've finished. Remove the sash and then remove all hardware, including the beads for parting, cords, and chains that keep the sash in place. Soften any putty that has been hardened with a heat gun set to medium and equipped with a shield to block the nozzle. Remove the old sash, and keep it in a labeled bag.

Sash Weights

If 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 reduce the energy cost. Sash weights are made of heavy iron or lead cylinders that are enclosed inside a concealed cavity, and connected by a rope to the movable window sash. These weights function as counterbalances, allowing you to open and shut the window repairs near me without the need for mechanical or electrical devices. The sash-weights are typically ignored or discarded by homeowners, and are turned into scrap when they fail. Consequently you might need to locate replacements.

It's difficult to retrieve the sash-weight that fell from the cavity, so you'll want to find one that fits properly. You will also require a new piece of string, a length of sashcord and some sashpulleys to tie the weights you are replacing to the cord.

Mortise and Tenon joints are used to join older wood windows. Pin punch and hammer can be used to cut off the wood pegs holding the parts together. The majority of these pegs are large on one side, and smaller on the other. It is important to remove first the smaller diameter sides. Sashes made later in the century made use of glue instead of pegs. They can be separated by cutting the glue line using an instrument, and then tapping the mortised area loose with a mallet.

Once the sash has been 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. The hole is surrounded by an unfinished wooden panel that can be removed to reveal the inside workings.

After the sash has been stopped and the access panel is removed, you are able to remove the old weight and replace it. Be sure to weigh the sash first because the weights you have might not be of the right size. After the new weight is installed, 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 protruding at the end of the string for future adjustments.

Sash Cords

Most double-hung windows of the past have a cord or chain connected to the weights that supports and keeps the sashes in balance in the jamb. Over time, these chains can become damaged and make it impossible to raise the windows. A new sash cable will give you the ability to move and lower the sash, and keep it in position when opened.

To replace sash cords the first step is to remove the access panels from the jambs. They are typically fixed or screwed in and must be removed or repositioned. You might be able to use a hammer or chisel to remove them however, it is always best to lay down dust sheets before starting 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 pull the narrow parting beads from their grooves. It's important to take your time as they're often wedged or nailed in place. If the sash is still in place, break the mortise and tenon joints using a hammer and pin punch or screwdriver, then remove the wood pegs on each component. The sash should be able to move freely now, but it may need some lubrication in order to feel less stiff.

Take a measurement of the length of sash chain/sash cord required to reach the sash slot at the bottom, and the pulley located at the top of the jamb. Cut the cord/chain and secure it in the step 6 above. You can use either a hammer, nails or screws. However nails are less likely than screws to cause damage.

If you don't have an item that replaces the old counterbalance system, it's best to keep the original balancing weights in place. It's not expensive to buy these from salvage shops for architectural purposes and they will be easy to install once you've got the sash open. Depending on the dimensions and shape of your window you may need to use one or two sashweights to keep the sash open.
