Weather Stripping

Wooden window sashes can give a classic look to your home. They are also sturdy and will last for many years when they are maintained properly. They may, however, become damaged or degraded with time, due to exposure and normal wear. Thankfully, sash repair experts can restore your windows back to their original condition and keep them looking fantastic for longer than replacement windows.

The first step to sash window repairs is addressing weather stripping, which can be found on both the sash and frame. It could cause drafts if worn out or loose. To fix it, begin by finding your window brand and the date on which the glass was manufactured (etched in the corner of the glass or on the aluminum spacer between panes). Remove the sash and mark its width and height so that you can find a replacement weather stripping that matches.

Next, remove the sash and set it on a work surface so that you can reach all four sides. If your sash has been double-hung, take out the ropes and weights that should be buried in the jamb lining. After removing the sash with the utility knife, take off the old weather stripping by hand or using a putty blade.

After the sash has been cleaned, you can replace the parting stops. These are long pieces that separate the sashes. Pam prefers to use the standard 1/2-inch by 3/4 inch window repairs trimming from the lumberyard. But, you can also use for a scrap piece of lumber.

After removing the stopper and trimming it to length and then apply a thin layer of glazing compound on the bottom of the sash. Smooth the compound with your putty tool, and allow it to dry for at least one day. When the putty is fully dried, you can apply an acrylic latex topcoat. This will help protect the putty, and give your sash an updated appearance.

Sash Hardware

The hardware that holds window sashes is prone to wearing out from age and use, and the result can be a door or window that can't be opened or closed easily. The good news is that repairing and replacing this hardware is typically relatively easy and affordable. If you're having difficulty opening a sash spray some oil into the jamb channel. Then, slide the sash out to see if this resolves the problem. If not, the issue is likely to be with the balance of the sash and you'll need to remove the sash to access the hardware.

The ideal situation is for window sashes to be able to open and close without effort, but this can be difficult when the weights are worn or if the sash's meeting rail isn't properly glazed. This can be due to various reasons, including an absence of maintenance or a mismatched weight rating.

If the hinge arms of a window begin to lose their elasticity, this could cause the sash to drag and eventually strike the frame in the corner opposite the hinge arm (Photo 1). To fix the problem, make sure that the sash is centered in the frame opening, and then take it off. If the sash is screwed onto the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

Due to hinges that are sagging, and a general lack in energy efficiency, older windows particularly those in older houses, could be difficult to open and close. In many instances, a few easy repairs can transform these windows into smooth operation again and save the homeowner cash on energy costs.

To make these repairs to the sash, it's important to have all of the necessary tools lined up before you begin. Mark the hinge channel location on the frame (Photo 1) using pencil. This will assist you in getting the channel back in place correctly when you're finished. Then, remove the sash and take off the hardware including the beads that separate (Photo 2) and the cords or chains that hold it in place. Soften any hardened putty with an electric heat gun set to medium and fitted with an nozzle shield. Remove the old sash, and put it in a bag with a label.

Sash Weights

Sash weights can be replaced to improve the performance of your window sash and reduce the energy cost. Sash weights are hefty lead or iron cylinders that are enclosed in a concealed cavity and connected to the movable the sash with rope. These weights act as counterbalances, allowing you to open and close the window without requiring mechanical or electrical devices. The sash weights are often ignored or discarded by homeowners, and are turned into scrap when they fail. Consequently you might need to search for replacements.

A weight from a sash that fell out of the cavity is difficult to get back and you'll need to find a replacement that is suitable for the. You will also require a new piece of string, a length sash cord, and a few sash pulleys to connect the new sash weights the sash cord.

Mortise and Tenon joints are used to join windows made of older wood. Pin punch and hammer can be used to cut off the wood pegs that hold the parts together. The majority of these pegs are big on one side and smaller on the other. It is essential to first remove the smaller diameter sides. Sashes that were 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 area loose using mallets.

Once the sash is freed then you can take out the sash stop and access the weight pocket. This is typically done by drilling a small hole in the bottom of each jamb. The hole is then covered with a wooden panel that can be removed to reveal the inner workings.

When the sash has been shut off and the access panel has been removed, you can take off the weight you used and replace it. Be sure to weigh the sash prior to you do this, since the weights that were previously used may be different in size from what you require. After the new weight is installed then tie a string to it and then thread it through the pulley for the sash. Then, you can nail the string to the frame, leaving a few inches of string protruding from the head to allow for future adjustments.

Sash Cords

Most double-hung windows of the past include a chain or cord connected to the weights that supports and keeps the sashes in balance in the jamb. Over time, these cords could break, making it impossible to raise the window. A new sash cable will give you the ability to move and lower the sash and keep it in place when opened.

The first step in replacing sash cords is to find and take out the access panels located in the jambs. These are usually fixed or screwed in and will need to be removed or relocated. You could use a hammer and chisel to prise them off, but it's always better to lay down dust sheets before commencing any work.

After you have removed the access panel, you can begin working on the sash. Make the small parting beads (also known as "tie rails") out of their grooves with flat bar or chisel. They are typically wedged into or nailed, but they can be prised free and it's worth your time here. If the sash remains 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, although it will probably need some lubrication if it feels stiff.

With the sash open Take a measurement of the sash chain to reach from the pulley in the top of the jamb to the sash slot in the bottom. Cut the cord or chain and secure it in the previous step. You can use nail, hammer or screws. However, nails are less likely to cause damage.

Unless you've bought an upgrade kit to replace the old counterbalance system, it is recommended to keep the original balancing weights in place. They're not costly and easy to install if purchased them from architectural salvage stores.
