Remove the sash, and mark its size and width so that you can find a replacement weather stripping that matches.

Then, remove the sash from its holder and place it on flat surfaces to allow you to see all four sides. If the sash is double glazed window repairs-hung, you'll need to take off the weights and the ropes that go with them, which should have fallen into the pocket that was intended to be in the jamb liner. After you have removed the sash using the utility knife, take off the old weather stripping by hand or using the putty blade.

Once the sash is clear, you can replace the parting stops. 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, but you could also use scrap wood.

After removing the parting stops and trimming them to your desired length, apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound using your putty tool, and allow it to dry for at least a day. Once it's fully cured and dried, apply a second coat of acrylic latex paint. This coating will protect the putty and give your sash a fresh look.

Sash Hardware

The hardware that supports window sashes is prone to wearing out from time and usage, and the result can be a window repair or door that can't be opened or closed easily. It's a good idea to know that replacing or fixing this hardware is usually simple and inexpensive. If you're having trouble opening a sash spray some lubricant into the jamb channel. Then, you can slide the sash open to see if it resolves the issue. If the issue persists it's likely to be due to the sash's balance.

Ideally, window sashes must be able to open and close without effort, but this is difficult when the weights are worn or if the sash's meeting rail isn't properly coated. This issue can be due to various reasons, including the lack of maintenance or a mismatched weight rating.

If the hinge arms of a window are beginning to sag, this can cause the sash to drag and eventually hit the frame in the corner that's directly opposite the hinge arm (Photo 1). To remedy the issue make sure the sash is aligned in the frame opening and then take it off. If the sash has been attached to the hinge arm, remove the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

Due to hinges that are sagging, and a general lack of energy efficiency, older windows particularly those in older homes, can be difficult to open and close. In most instances, a few minor repairs can turn these windows into smooth operation again and save the homeowner cash on energy costs.

It is essential to have the tools you need before you begin. Mark the location of the hinge channel on the frame (Photo 1) using pencil.

They are counterbalancers that allows the window to be shut and opened without using mechanical or electrical devices. When they fail, sashweights are usually neglected or not used by homeowners.

A weight in a sash that has fallen out of the cavity is difficult to recover It is therefore important to find a new one that fits correctly. You will also need an additional piece of string, a length sash cord and some sash pulleys that will tie the new sash weights the sash cord.

Mortise and Tenon joints are used to join old wood windows. Pin punch and hammer can be used to remove the wood pegs that hold the parts together. The majority of them are large on one side, and smaller on the other. It is essential to first remove the smaller diameter sides. Later sashes made use of glue instead of pins. They can be separated with a knife and a 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 in the bottom of each jamb. This hole is covered with a wooden panel that can be removed to reveal the inner workings.

Once you have the sash stopped and the access panel removed, you'll be able to take off the old sash weight and replace it with new. Make sure you weigh the sash prior to you do this, as the weights that were previously used may be different sizes than what you require.

Then attach the string to the boxed frame, but only leave a few inches of string protruding from the head for future adjustment.

Sash Cords

In the majority of double-hung windows the chain or cord is attached to the weights. This helps keep the sashes within the jamb balanced. Over time, these cords could break, making it difficult to raise the window. A new sash cable will restore the ability to move and lower the sash and keep it in position when it is opened.

The sash should be able move around freely now, however it might require some lubrication to make it feel less stiff.

With the sash open, measure enough sash cord/chain to reach from the pulley in the top of the jamb to the sash slot in the bottom. Cut the chain or cord, and then attach it as described in the previous step. You can use a hammer, nails, or screws. However nails are less likely than screws to cause damage.
