$0 call-out fee — any hour, any day · Available 24/7

Emergencies in North Sydney are as likely to be in an office as a home. In the towers along Miller, Walker and Berry Streets, a leak or a blocked drain on one floor can come from a connection made in someone else's fit-out years ago. In the older streets on the sandstone ridges, it is steep blocks shedding stormwater and sewers sitting close to rock.

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.

Kitchens and bathrooms added during fit-outs connect into risers that serve the whole building. Stopping water on one floor and finding the source can mean access to more than one tenancy, so building management needs to be in the loop from the first call.

Homes on the slopes towards Lavender Bay and the harbour shed water quickly. Where a pit has silted up or a line has lost its fall, heavy rain pools against the downhill wall of the house.

Rock sits close to the surface on the ridges, so the first job in a sewer emergency is clearing it and getting a camera down the line. Whether the fix afterwards means relining or cutting rock depends on what the camera shows.

Fixed price quoted before we start. $0 call-out fee.

Common Questions

Yes. We work with building management to isolate the water and find the source, including when it starts in another tenancy. Non-urgent follow-up work can be scheduled outside business hours.

If it is getting inside or under the house, yes. A silted pit or a broken stormwater line on a steep block is the usual cause. We clear the blocked pits and lines first, then trace the rest.
