Residential plumbing
Kitchens, bathrooms, laundries and outdoor areas benefit from smart plumbing design that keeps pipe runs efficient, water pressure consistent and future maintenance simple. We replace or relocate fixtures, install or upgrade hot water cylinders, fix leaks, repair taps and toilets, and tidy up legacy pipework so it is safe and accessible. If you are planning an alteration, we coordinate with your builder and other trades to keep your programme on track.
Commercial plumbing
Shops, cafes, offices and light industrial sites need robust systems and fast responses. We design and install plumbing that meets hygiene and durability requirements, size water heating to demand, and schedule works to minimise downtime for staff and customers. For multi‑stage projects we sequence tasks carefully, maintain clean work areas and provide progress updates so everyone knows what is next.
Renovations and new builds
Good plumbing starts early. We review plans, suggest fixture options and confirm pipe sizing and layouts before slab pours or wall linings. This avoids rework and ensures access points, isolation valves and future service clearances are in the right places. On site, our team works neatly, labels clearly and documents what we install so the next person who services the system can find what they need quickly.
We are based in Blenheim and service the Greater Marlborough Area - including the Sounds. Regular locations include Blenheim, Picton, Renwick, Havelock, Seddon, Ward, Spring Creek and Wairau Valley.
Hot water and water pressure solutions
Whether you prefer a mains pressure cylinder or a continuous flow system paired with gas, we size and specify hot water so showers are strong, temperatures are stable and running costs are sensible. We also address low or uneven pressure with correct pipe sizing, pressure limiting and valve selection. Our designs follow the intent of G12 Water Supplies in the Building Code so potable water remains safe and systems perform as designed. For reference, MBIE’s Building Performance guidance on water supplies outlines key compliance principles and good practice, which we align to in our designs and installations: MBIE Building Performance - Water supplies (G12).
In Marlborough, water quality and hardness can vary by network and location, especially for properties in the Sounds. We take this into account when recommending fixtures, valves and filtration so scale and corrosion are managed sensibly. You can learn more about local water information here: Marlborough District Council - Water quality.
Leak detection, repairs and emergencies
Dripping taps, constantly running toilets, damp patches and unexpected high water bills are signs of issues that need attention. We use practical methods to locate and fix leaks, replace failed valves and cartridges, and reinstate surfaces carefully. Where emergencies occur, we act fast, isolate the problem, make safe temporary repairs if required and return to complete permanent fixes with tidy workmanship.

They can. Water hardness and salinity can influence scaling and corrosion over time, especially in the Sounds.
