 Trustindex verifies that the original source of the review is Google. We had the pleasure of welcoming Drainage Control to our property in August this year to install a new drainage system. I’d like to extend my appreciation to Les and his team for their outstanding work. Their professionalism and expertise truly proved themselves during the recent severe weather, a situation that would have normally caused waterlogging after raining, but our place remained dry now. In addition, the construction is more like an artistic work in the gallery. They are highly skilled, communicative, and very flexible. I would recommend them.

Follow Les, and you’ll find yourself `less` worried, `less` concerned, `less` chaos, `less` flooding, and far `less` stressed in this Wellington city.

 Trustindex verifies that the original source of the review is Google. Les and his team did an excellent job, not cutting any corners but working in a cost effective way.  This may have taken slightly longer but as our job was not too urgent it worked well for us.  They were flexible and helpful to ways in which I could do some of the work (reconcreting the path) to reduce the cost with without reducing the quality of the drainlaying work.

Definitely recommend and would employ again.

Common drainage questions

Can’t see your question? Call us or send the details and we’ll help you work out what’s going on.

Why does my drain keep blocking?

A recurring blocked drain can indicate more than a temporary blockage. Common causes include tree roots, broken or displaced pipes, debris buildup or deterioration of older drains. A CCTV drain inspection can identify the underlying cause before repairs are recommended.

Do I need a CCTV drain inspection?

A CCTV inspection is worthwhile if a drain keeps blocking, if you suspect a broken pipe or if you need evidence of a drain’s condition. It shows the cause before any repairs are recommended.

What’s the difference between a plumber and a drainlayer?

Drainlayers specialise in the underground pipes that carry sewage and stormwater away from a property. Plumbers mainly work on water supply, fixtures and pipework inside the building.

Can you provide a drain report for an insurance claim?

Yes. Our CCTV drain inspections include footage and a written report, which can be used for insurance claims.

Which areas do you cover?

We work across Greater Wellington, including Wellington, Hutt Valley, Porirua and Kāpiti.
