How do you apply weatherstripping to doors and windows?

To apply weatherstripping to a house window you need such equipment as tin snips, a hammer, long-nose pliers, nails, and a putty knife. If you already have the needed equipment, you must follow the following steps:

1) Measure the height of the sash and cut the metal spring strips 2 inches longer using tin snips.

2) Open the sash and slide the stripping into the sash channel, as shown at left.

3) Hold the nails with the long-nose pliers and hammer them in.

4) Trim the stripping to fit around the pulleys and balances.

5) After installing the strips, pry them open with the putty knife, as shown at right. The spring will stick out more and help complete the weather seal.

6) Cut three strips to fit horizontally across the window. One goes along the bottom of the lower sash with its nailing flange flush along the inside edge of the window. The second attaches to the top of the upper sash. And the third attaches to the bottom face of the upper sash so it seals the two sashes when the window is closed.
