Plumbing Services in Blenheim & Marlborough

When it comes to plumbing in Marlborough, experience and reliability matter. At Marlborough Plumbing & Heating, we've been solving plumbing problems and completing installations across the Blenheim area and the wider Marlborough region for over 23 years. Our team of qualified, PGDB-licensed plumbers brings genuine expertise to every job — from a dripping tap in Renwick to a full bathroom renovation in Picton.

We handle the full range of residential and commercial plumbing work. That includes emergency callouts for burst pipes and flooding, routine maintenance and repairs, kitchen and bathroom tapware installation, hot water cylinder replacement, and new builds. Whether you're a homeowner dealing with an unexpected plumbing issue or a builder needing a reliable plumbing contractor for a new development, we have the skills, licensing, and local knowledge to get the job done right.

Bathroom & Kitchen Plumbing

Bathroom renovations are one of the most popular home improvement projects in Marlborough, and for good reason — a well-designed bathroom adds real value to your property. We work closely with homeowners and builders to plan and install complete bathroom plumbing, from shower and bath fixtures to vanity units and toilet connections. We're experienced with all leading brands stocked at Plumbing World and Reece, and we're happy to advise on the most practical and cost-effective choices for your space.

In the kitchen, we install sinks, tapware, waste disposal units, and filtration systems. Blenheim's water supply is drawn from the Wairau Aquifer and is mildly plumbosolvent — meaning it can, over time, corrode older copper pipes and brass fittings. If you've noticed a metallic taste in your water or premature corrosion on your taps and fittings, this is a likely contributing factor. We can assess your pipework and recommend upgrades or filtration solutions to address the issue.

Drainlaying & Drainage

Our team holds Master Drainlayers accreditation, which means we can carry out all aspects of below-ground drainage work. This includes new drain installations, blocked drain clearing, drain relining, and compliance inspections. For rural properties around Seddon, Awatere Valley, and the Marlborough Sounds, we're experienced with septic systems and effluent disposal systems that are common outside the reticulated network.

Emergency Plumbing

Plumbing emergencies don't wait for a convenient time. A burst pipe or blocked drain can cause serious damage quickly. If you're facing an urgent plumbing issue, call us directly on 03 577 9278 or 027 218 2329 — we'll assess the situation and respond as quickly as possible to minimise damage and restore your services. While we're primarily a Monday to Friday operation, we take urgent calls seriously and will advise you on the best course of action.

Hot Water Cylinders

We install, replace, and repair all types of hot water cylinders, including mains pressure and low-pressure models. If your cylinder is more than 15–20 years old, it's worth getting an assessment — older cylinders lose efficiency and can fail unexpectedly. We also install heat pump water heaters (see our Hot Water Heating page) and continuous flow systems. We're Stiebel Eltron Accredited Installers, meaning we're qualified to install and warranty their market-leading heat pump hot water units.

Wetback Systems

Wetback connections — where your wood fire or log burner heats your hot water cylinder — are popular in Marlborough, particularly in rural properties and older homes. We install and service wetback systems, ensuring safe and efficient connections that comply with current standards.

Whatever your plumbing need, the team at Marlborough Plumbing & Heating will give you honest, straightforward advice and quality workmanship. We use quality materials from trusted New Zealand suppliers, and we stand behind everything we do.
