About This Service
A downpipe takes the water from the gutter down to the stormwater. When it blocks, the gutter overflows at that corner of the house. When it leaks, rusts through or comes apart at the joints, water runs down the wall. When it's disconnected at the bottom, roof water soaks into the ground beside the house. We find where it's failing, whether that's the outlet at the gutter, a joint along the downpipe or the connection at the ground, clear any blockage, and repair or replace the downpipe, including in Colorbond steel. If the downpipe is clear but water still backs up at the ground, the problem is in the stormwater line underneath, and we check it on camera. You get a fixed price before we start, and 12 months on our workmanship.

The gutter overflows at one corner
When a gutter overflows next to a downpipe but nowhere else, the downpipe or its outlet is usually blocked.
Water spraying from joints
Joints that have pulled apart or seams that have rusted let water out down the wall, which stains render and wets the footings.
Rust and holes
Old steel downpipes rust from the inside, often at the bottom bend first.
Water pooling at the base
A puddle or soggy ground at the foot of the downpipe means the water isn't getting into the stormwater.
A downpipe pulling off the wall
Loose brackets let the downpipe move, which opens up the joints.
Blocked Above Ground or Below?
Above ground
If the downpipe itself is blocked, water backs up into the gutter. Leaves at the outlet are the usual cause.
Below ground
If the downpipe is clear but water bubbles out where it meets the ground, the stormwater line underneath is blocked or broken. We check it on a CCTV camera and clear it with the jet blaster.
Where the Water Should Go
Into the stormwater
Downpipes connect into the property's stormwater, which takes the water to the street or another approved point.
Never into the sewer
Roof water must not go into the sewer. Stormwater and sewer are separate systems.
Or into a rainwater tank
A downpipe can feed a rainwater tank, with the tank overflow connected to the stormwater.

Common Questions
FAQs
How do I know if my downpipe is blocked?
If the gutter overflows next to the downpipe in rain, or water backs up when you run a hose into the gutter there, the downpipe or its outlet is probably blocked.
Can you replace just one length of downpipe?
Yes, if the rest is sound. If the downpipe is rusted along its length, replacing the whole run usually makes more sense.
My downpipe isn't connected to anything at the bottom. Is that a problem?
Usually, yes. Roof water dumped beside the house soaks into the ground near the footings. It should go into the stormwater or a rainwater tank.
Can downpipes be connected to the sewer?
No. Roof water has to go to the stormwater, not the sewer.
Water bubbles out where my downpipe meets the ground. Why?
The stormwater line below is blocked or broken. We check it on camera and clear or repair it.
How much do downpipe repairs cost?
We give you a fixed price before we start, with a $0 call-out fee.
