Pipe Replacement Services in New Lynn

New Lynn's 1940s-60s homes along Great North Road, Clark Street, and Portage Road near LynnMall were built with galvanised steel water pipes. After decades, those pipes are corroded inside — restricting water flow, discolouring water, and springing leaks.

Rust builds up inside the pipe walls over decades, narrowing the bore until you're getting a trickle from taps that used to run full pressure. We replace old galvanised pipes with copper or PEX (cross-linked polyethylene) — both proven, long-lasting materials that won't corrode.

Every re-pipe job in New Lynn starts with a full assessment so we can map the existing pipework and quote accurately before any work begins.

Signs Your New Lynn Home Needs Pipe Replacement

—

Banging or rattling pipes — loose corroded fittings and weakened pipe supports.

—

Pipes over 40 years old — Most New Lynn galvanised pipes from the 1940s-60s era are well past their lifespan.

Frequent repairs — if you're patching leaks every few months, a full re-pipe saves money long-term.

Frequently Asked Questions

How much does pipe replacement cost in New Lynn?

A full re-pipe for a typical 3-bedroom New Lynn home ranges depending on the pipe material you choose and how accessible the existing pipes are. We assess your property first and provide a fixed quote — no hourly rate surprises.

How long does a re-pipe take?

Most re-pipe jobs take 2-3 days for a standard 3-bedroom house. We keep water running as long as possible and minimise downtime.

Should I choose copper or PEX?

Both are excellent choices. Copper is the traditional option with a proven 50+ year track record. PEX is flexible, faster to install, and often more cost-effective for homes where pipes run through tight spaces. We'll recommend the best option after the assessment.

Do I need consent for pipe replacement?

Like-for-like pipe replacement generally doesn't need a building consent. If we're changing the pipe layout significantly or working on the mains connection, we'll handle the consent process for you.
