Full Answer

Most windows in homes, apartments and offices have one or two locks. Each lock is connected to a screw or valve that opens and closes it. If the valves rust or get stuck in the closed position due to sloppy painting, the window cannot move. Rusty valves benefit from a liberal application of a hardware lubricant.

To open a window that is painted shut, cover the lock with a soft towel and gently knock it with a hammer. Tap the hammer from right to left. These and other screw locks open when turned counter-clockwise, and aiming the hammer blows accordingly encourages the lock to pop open.

Window locks are easy to reach from inside. It is much more difficult to open a window while standing outside. If the window is part of a door, it does not have a separate lock. Bypassing the window is still useful, however, because it makes it easy to reach inside and turn the doorknob. Insert the tip of a Philips head screwdriver into the bottom edge of the window and wiggle it around until it fits beneath the glass. Apply gentle, steady upward pressure until the window pops out.

    How do you measure windows?

    A:

    To measure windows for replacement, measure the width of the window between the jambs at the top, middle and bottom, and use the smallest measurement. Measure the height at the left, right and center of the window. Be sure to measure from the surface of the jambs, not from the extensions that hold the window. Measure the depth at the shortest point, and if you can't open the window, measure the width on the inside and multiply it by two.

    How can someone caulk around windows?

    A:

    To caulk around a window, scrape off old caulking with a putty knife, and clean the surface of any remaining caulking. Prepare a caulking gun for use, place the tip of the gun on the edge between the window and the wall, and compress the handle of the caulking gun to produce a steady stream of caulk. Move the gun along the window until the entire perimeter is sealed with caulk.
