Here's what some of our customers have to say about DVS® ...


"I don't have to go around in the mornings anymore with a big towel drying the wet windows. The DVS will save you money, work, and time in the long run."

Mrs Cullen from Island Bay, Wellington


"I've had a DVS for over 5 years & would have no hesitation in recommending this product to anyone. The service provided is 1st class."

Mr Neville Choat from Rotorua


"We used to have water pouring down our windows everyday. Since installing the DVS in our home we haven't had a single drop, not even when we cook or have showers."

Mr Roy Collis from Hamilton


"We have found the DVS to be really great. We get no condensation on our windows, and no sign of dampness or mildew on our curtains. We wouldn't be without it."

Mr & Mrs Howan from Kilbrinie, Wellington


"The DVS consultant left not one thing unturned. She has a great sense of humour and was not at all pushy with the sale. It was refreshing to have someone as good as Helen giving me a quote. I am always praising the DVS system and benefits to friends."

Ms Davison from Featherston


"We put aluminum joinery into our old stucco home. This effectively sealed in moisture. After installing the DVS, we found we had no condensation and our home is once again breathing."

Mr & Mrs Knowles from Taranaki


"We've had the DVS system now for 12 months and find the system to be all we were promised. Would recommend to anyone with moisture issues and even for heat."

Mr & Mrs Prescott from Otorohanga

"We have a holiday house in Turangi which is often left closed up for weeks at a time in between guests. The house had a faint mouldy smell (we thought from just being closed up) and we kept wondering why our son got a bad cough every time we stayed at the house. Since we had our DVS installed it has been fantastic. The house feels warmer when we arrive (as now it is really dry). And our son never gets sick while we are there -- which is obviously better for him and everyone else on holiday. Thanks DVS - we love our ventilation system!!"

Mr & Mrs Swarbrick, home in Turangi



"We are extremely happy with the system and will recommend it to anyone. We would go so far as to say we would never be in a home without one."

Mr & Mrs Coggan from Auckland


"We inherited the DVS system when we bought our home. It's a great system that keeps the house free of condensation and circulates fresh air. We strongly recommend it."

Mr V Pere from North Shore City


"I am very pleased with our DVS. Within 24 hours of installation, I noticed a marked improvement in condensation. It has been FANTASTIC!"

Mr Lewis from Orewa


"We've had a DVS for 10 years and recommend it to all and sundry to solve condensation problems and for air circulation around the home."

Mr Ruane from Tauranga


"We would not be without it. We never have to clear the windows or see any mildew on the curtains or walls."

E Dooley from Mt Maunganui


"We haven't seen mould in the two years we have had the DVS installed. Now we have a dry wardrobe, no condensation and no dampness. We are very happy with our DVS and happy to recommend it to anyone."

Mrs Davis from Hamilton


"We've had no condensation whatsoever 3-4 days after the DVS was installed. All our clothes are dry in our wardrobes and when we go away on holiday the house is nice and fresh when we come back. We find that the house is warmer because the DVS circulates the warm air around the house. I have been a strong supporter ever since we had it installed."

Mr Scott from Hamilton


"We had the DVS installed 3 days ago and for the first time in years we have woken up to clear dry windows. It's a great system!"

Mr & Mrs Prince from Whakatane


"We installed the DVS into our 99-year old concrete home. It turned our damp home into a livable house. We have found it much easier to heat and have virtually no condensation. We feel this is the best money we ever spent on the house."

Mr & Mrs Nixon from Timaru
