Downpipe repair and replacementSydney
A gutter is only as good as the downpipe it drains to. If water is backing up, leaking at the elbows or pouring out at ground level, we clear it, repair it or replace it.
- Blockages cleared from the outlet to the stormwater pit
- Colorbond, Zincalume and PVC downpipes
- Extra downpipes added where gutters overflow
Common downpipe problems
Downpipes block at the bends, where leaves and sludge collect, and at the base where they enter the stormwater line. A blocked downpipe makes the gutter above it overflow even when the gutter itself is clear. Steel downpipes also rust from the inside, typically at the bottom elbow and the back face against the wall where you cannot see it.
On older homes we often find downpipes that discharge straight onto the ground beside the house. Over time that undermines footings and causes damp in sub-floor areas.
Repair, replace or add
We clear blocked downpipes by hand and with water jetting, and can run a camera where the blockage is underground. Split or rusted downpipes are replaced in round or rectangular Colorbond, Zincalume or PVC to match what is there, with new brackets and a proper connection at the bottom.
Where a long gutter run has only one downpipe, adding a second one is often the cheapest way to stop overflow. The number of downpipes needed depends on roof area and local rainfall intensity under AS/NZS 3500.3.

Downpipe repair & replacement: common questions
How do I know if my downpipe is blocked?
The gutter above it overflows in rain, water bubbles out of joints in the pipe, or little or no water comes out at the bottom. Tapping a blocked steel downpipe gives a dull sound instead of a hollow one.
How many downpipes does a house need?
It depends on roof area, gutter size and rainfall intensity. The National Construction Code housing provisions allow a maximum of 12 metres of gutter per downpipe, and fewer where the roof area is large.
Can downpipes be connected to a rainwater tank?
Yes. Downpipes can be redirected to a tank with a first-flush diverter and leaf screen. The tank overflow still needs to connect to stormwater.
