Drainage Services
Auckland

A straightforward drain unblocking typically costs $200-$400 including GST. This usually involves machine clearing with an electric eel. If the blockage is more severe or requires hydro jetting (high-pressure water), expect $400-$800. A CCTV inspection is usually $300-$500 and is highly recommended to identify the root cause and prevent recurring blockages.

As a property owner, you're responsible for all drainage within your property boundary — from your house to the property boundary. Beyond your boundary, the public sewer is Watercare's responsibility. If the blockage is in the public sewer, contact Watercare on 09 442 2222. If it's on your property, that's where we come in. We can determine the location during a CCTV inspection.

Absolutely — it's one of the most important pre-purchase inspections you can do. Many Auckland homes, particularly those built before the 1970s, have earthenware drains that are prone to cracking, root intrusion, and collapse. A full drain replacement can cost $10,000-$30,000+, so discovering this before purchase gives you negotiating power or saves you from a costly surprise.

Recurring blockages usually indicate an underlying issue rather than just a one-off. Common causes in Auckland include: tree root intrusion (very common with older earthenware pipes), a belly or sag in the pipe causing water to pool, pipe collapse or cracking, grease buildup (particularly in kitchen drains), or incorrect pipe falls. A CCTV inspection will identify the exact cause and allow us to recommend a permanent fix rather than repeated clearing.

Repairs to existing drains (like-for-like replacement) are generally exempt from building consent, though the work must be done by a registered drainlayer. New drainage installations, significant alterations, or connections to the public sewer typically require Auckland Council building consent and Watercare approval. We'll advise you on what's needed for your specific situation and handle the paperwork.
