Inspection and maintenance each spring and autumn can prevent most serious gutter problems.

You may need permission from you local council and/or water and power authorities before work is carried out, and we suggest you make contact before you start your project.

Tools Required

  • Whisk Broom
  • Extension ladder
  • String Line
  • Hammer
  • Level

Always keep tools and materials away from children. Read the instructions before beginning your project.

General Maintenance

Remove leaves and other debris with a whisk broom that fits inside the gutter and a garden hose to wash away the small pieces. If downpipes need cleaning, use the garden hose, threading it down the pipe with the water and nozzle turned on full blast. Danger: If using a hose do not walk on any wet roof.

Keep out leaves with gutter guard. This is a plastic mesh that easily fits into the gutter and stops leaves blocking gutters and downpipes. Gutter guard should be fitted at the end of summer and cleaned if necessary through winter.

If gutters develop pinhole leaks and leaks at connections, you can usually seal these breaks with roofing sealant.

Check gutter straps and hangers on an annual basis. If loose, re-nail. If broken, replace.

Installing Guttering

Whether you are installing new gutters and downpipes or replacing sections or parts of an existing system, you’ll find the project fairly easy to do with normal tools. Gutter systems, both plastic and metal, go together almost like a Lego set; modern silicones and slip-joint connections eliminate soldering and all of its problems.

Existing gutter and downpipe shapes can usually be matched from stock. If however you have an unusual profile this may require special manufacture, or if this is not practical, replace sections in complete runs with a pattern that closely matches the existing.

Guttering must have a fall. If you are utilising the same slope that existed on the old guttering, check its fall prior to removing by running a hose at one end. If the water is ponding, the end opposite the downpipe will need raising.

After removing old guttering and any damaged brackets, fasten the two end brackets first. Spring a chalk line onto the fascia and attach remaining brackets to the line at the recommended spacing. Then install the gutter.

Joins and stop ends can be carried out after installation. Dropper sections for downpipes should be riveted and sealed in place at gravel level.


To calculate how many lengths and accessories you need for a project, simply measure along the fascia of the house – from corner to corner. Note where the gutter makes inside and outside turns, where downpipes are located (and length), and how many end caps are needed for the project. You can determine from these measurements and components how many hangers, connectors, downpipes, etc., you have to buy. It’s a good idea to make a sketch of the system on paper, noting the distances, corners and so on. When you’re finished you have an “automatic” shopping list.

    In some states and countries you must have proper guttering to comply with building regulations. Some home insurers also consider your guttering.
