Spring Metal on Doors Spring metal weatherstripping is installed on the doorjamb next to the door stop. Measure along the sides and the top of the door jamb and cut the spring metal to the correct length with tinsnips. Begin with the hinge side of the doorway, then do the latch side above and below the latch plate. Install the top piece last miter-cutting the corners. Tack each strip at the ends to align it and stretch it flat against the jamb before nailing along its length.
Some manufacturers provide a strip to fit behind the strike plate.
You can also trim a piece to fit When all the strips have been installed, run an awl or a screwdriver along the outside edge to spring the metal spring into position. Now that we're ready to weatherstrip the windows, it is best to begin by discussing the different types of windows, in relation to the types of weatherstripping. Manufacturers require different fastening techniques. But the plastic V-types run a very close second. A double-hung window is probably the most complicated to weatherstrip.
