To fix it, begin by finding your window brand and the date of manufacture for the glass (etched in the corner of the glass or on the aluminum spacer between panes). Then, take the sash off and mark its height and width so that you can locate new weather stripping that matches.

Then, take the sash from its holder, and place it on an even surface that allows you to see all four sides. If the sash is double glazed window repairs near me-hung, you'll also need to remove the weights and their accompanying ropes, which should have fallen into the intended pocket in the jamb liner. After you have removed the sash using the utility knife, remove the old weather stripping by hand or using the putty blade.

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

After removing the stopper for the parting and trimming it to length and then apply a thin layer of glazing compound over the bottom of the sash. Smooth the compound with your putty knife, and then 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 look.

Sash Hardware

The hardware that supports window sashes can wear out with time and use. This can result in the window repairs or door that is difficult to open or close. It's a good idea to know that replacing or repair of this hardware is typically straightforward and cost-effective. If you're having difficulty opening a sash, spray some oil into the jamb channel. Then, slide the sash open to see if it resolves the issue. If not, the issue is likely to be with the sash balance and you'll have to take off the sash in order to access the hardware.

Ideally, window sashes should move open and shut without effort, but this is difficult if the weights become worn or if the sash's meeting rail isn't properly glazed. This issue could be caused by a number of reasons, such as insufficient maintenance or an incorrect weight rating for the specific sash.

If the hinge arms of a window begin to slide, this could cause the sash to slide and eventually strike the frame in the corner directly opposite the hinge arm (Photo 1). To remedy the issue ensure that the sash is centered in the frame opening and then take it off. If the sash has been screwed onto the hinge arm, unbolt the hinge and replace it. (Photo 2). Next, install the new sash (Photo 3).

Old windows, especially those in older houses, can be difficult to open and close due to hinges that are sagging and general lack of energy efficiency. In many cases it is a matter of making a few minor adjustments that can help these windows function smoothly once more and help homeowners save money on their energy bills.

It is important to have the tools you require before you begin. Mark the location of the hinge channel on the frame (Photo 1) with a pencil.

Sash Weights

Sash weights are able to be replaced to improve the performance of your window sash and decrease the cost of energy. Sash weights are hefty lead or iron cylinders enclosed inside a hidden compartment and linked to the moveable the sash with rope. They provide counterbalance which allows the window to be opened and closed without using mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners and turned into scrap when they fail. Consequently you may have to find replacements.

A weight in a sash that has fallen out of the cavity is difficult to recover, so you will want to locate a new one that fits properly. You will also need an additional piece of string, a length sash cord, and a few sash pulleys to tie the new sash weights the sash cord.

Older wood windows are joined with mortise and tenon joints. Hammers and pins can be used to take out the wood pegs that hold the parts together. Most of these pegs have large diameters on one side and a smaller diameter on the other side, so it is important to remove the smaller-diameter ones first. Sashes that were made later in the century made use of glue instead of pegs. They can be separated by cutting through the glue line using a knife, then tapping the mortised area loose using a mallet.

Once the sash is freed, you can remove the stopper on the sash and get access to the weight pocket. Usually this is accomplished by drilling an opening in the bottom of each jamb. The hole is then covered with a wooden panel that can be removed to reveal the interior 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 before you do this, since the weights that were previously used may be different sizes than the one you need. Once the new weight is installed you can tie a string around it and then thread it through the sash pulley. 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

In the majority of double-hung windows, a cord or chain is connected to the weights. This keeps the sashes in the jamb balanced. Over time, these chains can become damaged and make it impossible to raise windows. A new sash cable will restore the ability to raise and lower the sash, and ensure it stays in place when it is opened.

The first step in replacing sash cords is to find and remove the access panels within the jambs. They are usually screwed or nailed into and require removal. It may be possible to remove them using a hammer or chisel, but it is always better to lay out dust sheets before starting any work.

After the access panel has been removed, you can begin working on the sash. Utilize a flat bar, or chisel, to pry the small parting beads from their grooves. They are usually wedged in or nailed but can be removed and it's worth your time. If the sash remains in place, break the mortise and tenon joints free with a hammer or screwdriver and then take out each wood peg. The sash should move freely, however it might require some lubrication in order to feel less stiff.

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