Instructions

- 1
  Measure your window's length on the edge where you plan to install the aluminum trim. Factor in the appropriate amount of overhang for each window. The degree to which the aluminum trim coil should extend beyond the window's corners varies, depending on the style of coil and your personal preference.
- 2
  Mark the location for each edge of trim coil with chalk on your home's exterior.
- 3
  Measure the appropriate length for the trim piece. Lay a straightedge across the trim and trace a scoring line into the trim with the chalk.
- 4
  Score the length of aluminum trim coil with a utility knife. Bend the trim back and forth until it breaks at the scored line.
- 5
  Hold the aluminum trim coil steady against the house. Give the trim a minimum clearance of 1/16-inch. Like wood, aluminum needs space to expand and contract as the weather changes.
- 6
  Drill two 3/4- to 1-inch pilot holes at each end of the length of trim with a power drill.
- 7
  Hammer aluminum nails into the pilot holes to secure the aluminum trim coil to the house.
