Then, remove the sash and mark its height and width to find new weather stripping that matches.

Then, remove the sash and set it on a table so that you can reach all four sides. If your sash has a double-hung, you'll need to remove the weights as well as 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 with a putty knife.

After the sash has been cleared it is time to replace the parting stops. These are long pieces that split the sashes. Pam likes to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard. However, you could also use a piece of scrap wood.

After removing the parting stops and cutting them to the desired length, apply a thin layer of glazing compound to the bottom of the sash.

If the hinges on a window begin to sag this could cause the sash to drag and eventually hit against the frame in the opposite corner (Photo 1). To address this problem, first ensure that the sash is firmly seated in the opening of the frame and then take it out of the window. If the sash has been screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).

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

Sash Weights

Sash weights are composed of iron or lead cylindricals that are contained inside a concealed cavity, and attached by ropes to the movable Window Repair (Global.Su) sash. These weights provide counterbalance which allows the window to be shut and opened without using mechanical or electrical devices.

Mortise and Tenon joints can be used to join windows made of older wood. The wood pegs that keep the parts together can be removed by pin punches and hammers. Most of these pegs have an enormous diameter on one side and a smaller size on the other, which is why it is important to remove the small-diameter sides first. Later sashes used glue instead of pins. They can be cut by using a knife or mallet.

After the sash is removed and removed, you can take off the stopper on the sash and get access to the weight pocket. This is usually done through an opening at the bottom of each jamb. This hole is covered with an unfinished wooden panel that can be removed to reveal the inner workings.
