Burst pipes, sewage overflows, leaks and no hot water across Castle Hill, any hour. We stop the damage first, then fix the cause.

Plumbing emergencies in Castle Hill usually trace back to the ground. Reactive clay moves the long drainage runs under Hills homes, so a sewer can crack or separate well away from the house, and a toilet that keeps blocking is often the first sign. Castle Hill also has shops and offices, with the business park at Norwest next door, so we attend commercial callouts here as well as homes.

Repairing a water pipe a demolition crew put through during a bathroom strip-out. Trade damage is one of the more common reasons we get called out mid-job.

A concealed leak found in a Sydney office. By the time it shows on the floor it has usually been running for weeks.

Reactive clay swells and shrinks with the seasons and pulls joints apart. Debris catches at the fault until the line blocks. Clearing it fixes the emergency; a camera finds the structural cause.

A toilet that blocks along with a shower or floor waste usually points further down the line, which on a long Hills drainage run can be well away from the house. Plunging clears the symptom, not the cause.

Clay does not absorb well, so stormwater has to be carried away. Where a system is undersized or partly blocked, water ponds on the surface and can reach the house in heavy rain.

Common Questions

A toilet you can't use is urgent, and one that keeps blocking is telling you something. We clear it first, then put a camera through the line, because on Hills blocks the cause is often a cracked or separated joint further down.
