Pipe Replacement Services in Newmarket

Newmarket's 1920s-50s bungalows along Broadway, Khyber Pass Road, and Remuera Road were built with galvanised steel water pipes. After 70+ years, those pipes are corroded inside — restricting water flow, discolouring water, and springing leaks.

With a mix of original bungalows and modern apartments, Newmarket has plumbing that spans every era. 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 are proven, long-lasting materials that won't corrode. Every re-pipe job in Newmarket starts with a full assessment so we can map the existing pipework and quote accurately before any work begins.

Your Options

Full Re-Pipe (Copper)

Complete replacement of all galvanised pipes with copper. The gold standard for Newmarket homes.

Full Re-Pipe (PEX)

Flexible PEX piping — faster to install, fewer joints, and great for retrofitting through walls and floors.

Partial Pipe Replacement

Replace the worst sections first. Good option when budget is tight but pipes are failing in Newmarket homes.

Galvanised to PEX

Direct swap from old galvanised steel to modern PEX. The most common upgrade we do in Newmarket.

Signs Your Newmarket Home Needs Pipe Replacement

Brown or rusty water — corroded galvanised pipes shedding rust into your Newmarket water supply.

Low water pressure — rust buildup narrows the pipe bore, starving taps and showers of flow.

Pinhole leaks — small leaks appearing in walls or ceilings as corrosion eats through pipe walls.

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

Pipes over 40 years old — most Newmarket galvanised pipes from the 1920s-50s 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 Newmarket?

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

How long does a re-pipe take in a Newmarket home?

Most Newmarket re-pipe jobs take 2-3 days for a standard 3-bedroom house. We keep water running as long as possible and minimise downtime so your Newmarket household isn't disrupted for long.

Should I choose copper or PEX for my Newmarket home?

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

Do I need consent for pipe replacement in Newmarket?

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