Plumbing & Heating in Rai Valley

Rai Valley sits on the Rai River in the southern Marlborough, about 50 kilometres northwest of Blenheim via the scenic Pelorus Valley. It's a small community in a beautiful, heavily forested valley — and one of the wettest parts of the Marlborough region.

Annual rainfall in the Rai Valley area reaches 1,600–1,800mm, and the combination of high rainfall, dense bush, and cooler temperatures makes moisture management critical for homes in the area. Condensation, mould, and damp are common issues in houses here, particularly older ones built without modern vapour barriers and insulation. A quality positive pressure ventilation system makes a significant difference to air quality and prevents the structural damage that long-term dampness causes.

We service the Rai Valley area and surrounding communities including Pelorus Bridge and Canvastown. Many properties in this area are on private water supplies — rainwater tanks, bores, or river-fed systems. We have extensive experience with rural water supply systems and can design, install, and service complete water treatment solutions.

Rai Valley's cold winters (the valley can trap cold air and frost heavily even by Marlborough standards) make heating a priority. We've installed both underfloor and radiator systems in valley properties, and the results speak for themselves — a warm, dry home in the Rai Valley is a pleasure to live in year-round.
