Downpipe Installation Services

Downpipes are the critical link between your gutters and the stormwater system. Incorrectly sized, poorly placed or missing downpipes lead to gutter overflow, foundation erosion, damp subfloors and landscaping washout. We design and install Colorbond downpipe systems that efficiently carry roof water from your gutters to stormwater drains, soakaway pits or rainwater tanks. Every installation is calculated to handle your roof's catchment area and local rainfall intensity, ensuring your property stays dry even in the heaviest storms.

Benefits

Prevent Foundation Damage

Properly routed downpipes direct water away from your home's foundations, preventing erosion, cracking and moisture ingress.

Reduce Gutter Overflow

Adding or upgrading downpipes increases your gutter system's drainage capacity, reducing the chance of overflow during storms.

Rainwater Harvesting Ready

We can connect downpipes to rainwater tanks with first-flush diverters, turning roof runoff into a usable water resource.

Our Process

1

Drainage Assessment

We assess your roof catchment area, existing drainage and stormwater connection points to determine the optimal downpipe layout.

2

Design & Quote

A downpipe layout is designed with correct sizing and placement, and a detailed quote is provided including colour selection.

3

Install Downpipes

Colorbond downpipes are cut, shaped and fixed to the wall with brackets, then connected to gutter outlets with sealed pop-riveted joints.

4

Connect to Drainage

Each downpipe is connected to the stormwater drain, soakaway pit or rainwater tank, and the full system is flow-tested.

Frequently Asked Questions

How many downpipes does my house need?

The number depends on your roof's catchment area and the gutter profile. As a general rule, a downpipe is needed every 12 to 15 metres of gutter run. We calculate the exact requirement during our assessment.

Can downpipes be connected to a rainwater tank?

Yes. We regularly connect downpipes to rainwater tanks and can install first-flush diverters that discard the initial dirty runoff before clean water enters the tank.

What is the difference between round and square downpipes?

Both perform equally well. Round downpipes suit traditional and heritage homes, while square downpipes offer a more contemporary look. Square profiles also sit flatter against the wall.
