Mr. Clog Plumbing

Plumber North Sydney

Office, strata and older-home plumbing across North Sydney, Waverton and McMahons Point.

Our guarantee: 12 months on our workmanship, in writing. What it covers

North Sydney is one of Sydney's main office centres, with towers along Miller, Walker and Berry Streets, and a growing number of apartment buildings around the Victoria Cross Metro station. Behind them are streets of Victorian and Federation houses on sandstone ridges that fall towards the harbour and Lavender Bay.

Commercial and residential work sit side by side here. In the office towers and mixed-use buildings, plumbing faults usually mean tenancy fit-outs, shared risers and work booked around building hours. In the older streets it is the sandstone that matters: rock sits close to the surface, so trenching is slow, and a relined pipe is often a better answer than a dug-up one. North Sydney Council is the local authority for both.

$0 call-out fee — available 24/7, 365 days a year across North Sydney and nearby suburbs.

Every part of Sydney has its own plumbing character, shaped by the age of the housing, the ground it sits on, and the weather it takes. Here is what we are called out for most often around North Sydney.

Office kitchens and bathrooms added during fit-outs connect into risers that serve the whole building. A slow drain or a leak on one floor can originate in a connection made years ago by someone else, and locating it needs access to more than one tenancy.

The ridges through North Sydney are sandstone with little soil cover. Replacing a damaged sewer line by digging means cutting rock, so a camera inspection to see whether relining will work is worth doing before anyone quotes an excavation.

Houses on the slopes towards Lavender Bay and the harbour shed stormwater quickly. Where a pit has silted or a line has lost its fall, the result in a storm is water pooling against the downhill wall of the house.

Common Questions

Yes. Commercial work that needs water isolated is usually best done outside business hours, and we schedule it with building management.

Yes. Testable backflow prevention devices generally need an annual test by an accredited plumber, and we can test, repair and lodge the results.

Not necessarily. If the pipe is intact enough to line, relining through existing access points avoids cutting sandstone altogether. A camera inspection tells us which.
