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

Then, you can remove the sash from its holder and place it on an even surface that allows you to reach all four sides. If your sash was double glazing window repairs-hung, you must remove the weights with their ropes that should have fallen into the pocket in the jamb lining. Once you've removed the sash, use a utility knife to cut away the weather stripping from the corners. Then, take it off by hand or with a putty knife.

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

After removing the parting stop and cutting it to length, apply a thin coat of glazing compound to the bottom of the sash. Smooth out the compound using your putty knife, then let it dry for at least a few days. After the putty has completely dried it is possible to apply an acrylic latex topcoat. This will protect the putty and give your sash a fresh appearance.

Sash Hardware

The hardware that supports window sashes may wear out with time and use. This can result in windows or doors that is difficult to open or close. It's good to know that replacing and repair of this hardware is typically simple and inexpensive. If you are having trouble opening a sash, spray some grease into the jamb channel. Then slide the sash up and open to see if this resolves the issue. If the problem persists it's likely that the sash balance is off. You'll need to take off the window sash in order to get access to this part of the hardware.

Window sashes should be able to open and close with minimal effort. However, this could be difficult if weights are worn out or the sash-to-rail meeting rail is not properly coated. This issue can be due to various reasons such as an absence of maintenance or an unmatched weight rating.

If the hinge arms on windows begin to slide, this can cause the sash drag and eventually hit against the frame in the opposite corner (Photo 1). To address 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 has been screwed to the hinge arm, you'll need to unscrew the hinge arm and replace it (Photo 2). Then, you can install the new sash (Photo 3).

Old windows, particularly those in older houses, can be difficult to open and close due to sagging hinges and an overall inefficiency. In most instances, a few easy repairs can transform these windows into smooth operation and save homeowners money on energy bills.

It is essential to have the tools you require before you begin. Begin by marking the location of the hinge channel on the frame using a pencil (Photo 1). This will assist you in getting the channel back in place correctly when you're finished.

Sash Weights

Whether your window sash repairs are to replace a damaged cord or just to ensure that the windows are functional and functional, replacing worn-out weights on sash can improve sash operation and cut down on the energy cost. Sash weights are composed of iron or lead cylinders that are encased in a hidden cavity and attached by ropes to the moveable window sash. They function as counterbalances, allowing you to open and close the window without requiring mechanical or electrical devices. If they fail, sashweights are usually left unnoticed or disabled by homeowners.

A sash weight that has fallen out of the cavity is difficult to retrieve and you'll need to locate a new one that fits properly. You will also require a new piece of string, a length of sashcord and a few sashpulleys for tying the new weights to the cord.

Older windows made of wood are joined using mortise and tenon joints. Hammers and pins can be used to cut off the wood pegs holding the parts together. The majority of them have large diameters on one side and a smaller one on the other side, so it is crucial to take out the small-diameter sides first. Later sashes utilized glue instead of pins. They can be separated with a knife and mallet.

After the sash has been removed and removed, you can take off the stopper on the sash and get access to the weight pocket. This is typically done by drilling an opening in the bottom of each jamb. This hole is then covered by an access panel of wood that can be ripped off so that you can see the inner workings of the frame.

Once the sash is stopped and the access panel is removed, you can take off the weight you used and replace it. Weigh the sash first to ensure that the weights you've got may not be the correct size. After the new weight has been installed, thread an appropriate length of string through the pulling mechanism. Then nail the string to the frame, but only leave a few inches of string sticking out from the head for future adjustment.

Sash Cords

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

The first step in replacing cords for sash is to locate and remove the access panels within the jambs. They are usually screwed or nailed into and need to be removed. It is possible to remove them using the hammer or chisel however, it is best to lay out dust sheets before starting any work.

After you have removed the access panel, you are able to begin to work on the sash. Utilize a flat bar, or chisel to pull the narrow parting beads out of their grooves. It's important to be patient because they are usually stuck or nailed to the floor. If the sash is still in place, pry out the mortise and the tenon joints by using a hammer and pin punch or screwdriver, then remove the wood pegs attached to each component. You should be able to move the sash back and forth freely, although it may require oil if it feels stiff.

Measure the length of sash cord/chain needed to reach the sash slot on the bottom, and the pulley on the top of the jamb. Cut the chain or cord and attach it in the previous step. You can employ a hammer and nail or screws, but nails are less likely to cause damage.

If you haven't purchased a kit that replaces the old counterbalance system it's best to keep the original weights for balancing in place. It's cheap to purchase them from architectural salvage stores and they'll be simple to install once you've got the sash unlocked.
