Rain gutters and downspouts are designed to move water away from a structure to prevent flooding and moisture damage. Gutters are constructed of PVC, aluminium and, in rare cases, wood. If you want to create an additional downspout in a gutter, create a hole to allow for water drainage. Make the hole using power tools, such as electric drills and jigsaws. A downspout connector is inserted into the hole and screwed into place.

Moderately Easy

Things you need

  • Downspout connector

  1. 1

    Place a connector against the bottom of the gutter where the downspout will be located. Trace around the outer edge of the connector with a pencil to create a cutting layout.

  2. 2

    Equip an electric drill with a 1/2-inch bit designed to cut through the specific gutter material, such as aluminium. Drill a hole through the gutter at each corner of the layout.

  3. 3

    Slip a jigsaw blade through each hole and cut along the line until you reach the opposite side. Continue cutting until the opening is complete.

  4. 4

    Sand the edges of the hole with sandpaper or a file to smooth rough edges. Clean any debris from the area.

  5. 5

    Seal cut metal gutter edges with rustproof spray paint.

Tips and warnings

  • Wear safety glasses to protect your eyes from flying debris when using power tools.
  • Watch out for sharp edges when cutting aluminium and other metal gutters.
