Nathan Williamson, founder of DrainPro, comes from three generations of drainage professionals and over 45 years of valuable industry experience and expertise. So, it came as no surprise to anyone when he decided to start his own drainage company in 2014. Since then, the business has grown considerably and now has operations in Christchurch, Central Otago and soon to be expanding into Auckland as well. Our headquarters are in Rolleston, Christchurch which houses our office-based team members and full range of support staff.

The success of our business has been built on providing responsive, high quality, specialist services to residential builders supporting better outcomes for their projects.

We actively partner with some of New Zealand's best known residential building brands providing modern, well qualified and competitive services including new drainage, septic systems and other underground services.

We know how important it is for you to get things done on time and keep costs down, which is why we've created efficient project delivery systems to help you achieve just that. For residential new builds, we can complete both the laying and backfilling in one day. This means less disruption to other tradies working on-site and increase efficiencies for your build time. By not holding up other work on-site, you can move on with other aspects of the build quickly.

Increased efficiency for us means we can keep our costs down and increase your cost efficiencies for each job.

For one-off projects, we provide full quotes free of charge. For ongoing business relationships, we can provide you with set rates, that way you don't need to talk to us when you've got a new job to quote, this is just another way we're working smarter to save you time.

You can trust that every DrainPro team member that turns up to your site are either Certified or Registered Drainlayers, or apprentices. Everyone who works on-site for DrainPro is put through their Registered Drainlayer Apprenticeship as soon as they start.

It's important to us to deliver a quality service to each and every customer. This is why we invest in training our people and make sure that everyone working on your site has the skills and knowledge to complete your job to the highest possible standard.

All work completed by DrainPro is quality assured and covered by the Master Drainlayers 12-month Guarantee. We stand by our work and pride ourselves on delivering the best quality job and service you can get.
