Fix a leaky gutter: a handy how to

What you will need

  • Ladder, tall enough to reach your gutters
  • Wire brush or sandpaper
  • Clean rags and a solvent (such as acetone)
  • Fibreglass or metal patch
  • Scissors or tin snips
  • Fibreglass resin or gutter sealant
  • Paintbrush or putty knife
  • Work gloves (if required)
  • Pop rivets and rivet gun (for metal patches)

Readying the surface before you begin

  • Be diligent about cleaning away dirt or rust with a wire brush or sandpaper, then wipe the area with solvent and allow it to dry completely.

Using a fibreglass patch

1. Cut your fibreglass patch to size

  • When using a fibreglass patch, cut a piece that will cover the area that you're patching with an overlap of 5 centimetres (2 inches) on all sides.

2. Make the bed

  • For a fibreglass patch, use a paintbrush to apply a thin coat of prepared fibreglass resin to the gutter.
  • Wear gloves so the resin doesn't touch your hands.

3. Secure your fibreglass patch

  • Press the patch into the resin with a rag.
  • Apply a thin coat of resin over your patch,
  • Then, after 24 hours, sand the patch and apply another coat of resin.

Using a metal patch

1. Cut your metal patch to size

  • If you opt to use a metal patch, you'll need to allow an overlap of 10 centimetres (4 inches) between the hole and your patch.

2. Make the bed

  • For a metal patch, use a putty knife to spread a 3 millimetre (1/8 inch) layer of sealant over the entire surface that you'll be patching.

3. Secure the metal patch

  • Press the patch into the sealant with a rag.
  • Then, rivet the patch at both ends, and spread a layer of sealant over the edges.
  • Leave your patch to dry.

Follow this handy how to and you'll be able to keep your home from taking on water damage.
