Double Dz Drainage is a qualified drainlayer covering all of Wellington City — fixed quotes, CCTV before we dig, and the full range of drainage work. We cover Karori, Kelburn, Newtown, Island Bay, Miramar, Khandallah, Johnsonville and everywhere in between.
Wellington City drainage is its own beast. A lot of Karori, Mt Victoria, Kelburn, Aro Valley and Newtown homes are over 100 years old with original earthenware lay. They've usually been patched a dozen times, and most "blocked drain" calls are really old pipes asking to be replaced.
Add the slopes — Brooklyn, Khandallah, Mt Cook — and access for excavators becomes a real planning exercise. We run the camera first, talk through the options, and quote it fixed before anyone touches a spade. No hourly clock, no surprises on the invoice.

Wellington drainage guides: what a CCTV drain inspection finds, when to re-lay old drains, why “flushable” wipes block drains, and when a section needs a soak pit.
Seven drainage services. Same crew. From a Karori blocked toilet to a full Khandallah new-build scope.
Hydro-jetting, root-cutting, after-hours. Camera included on repeat blockages.
Pre-purchase reports for old Wellington homes. Footage on USB or shared link.
Old Karori, Newtown and Aro Valley earthenware replaced with modern uPVC.

Full drainage scope for new Khandallah, Johnsonville and Karori builds.
Scheduled CCTV + hydro-jet servicing so a Wellington drain never becomes a 2am emergency.
Real 5.0★ reviews from Wellington and Hutt Valley customers — verified across all 10 Google reviews.
Devon has gone out of his way to not only help us after hours with a blocked drain in our bathroom but gave us some great pointers on drain care. One thing that sets them apart from the bigger companies is his energy and willingness to just get things done.
We had an urgent drainage issue that needed to be fixed with our older home. The team responded quickly and they were able to fix the issue promptly and stop any further damage. Highly recommend these guys!
Really impressed with the level of professionalism. They showed up on time, explained everything clearly, and got the drainage issue sorted quickly. Would definitely recommend.
Yes — Karori, Kelburn, Mt Cook, Newtown, Island Bay, Miramar, Khandallah, Johnsonville, Mt Victoria, Brooklyn, Aro Valley, Thorndon, Hataitai, Kilbirnie and Lyall Bay. We're based in Upper Hutt so travel is roughly 40–50 minutes depending on traffic.
Because the work is the same, and we charge a fixed quote up front — no hourly clock penalising us for travel time. Most Wellington City customers come to us through word-of-mouth from their Hutt or Wairarapa friends. We've never lost a job over the postcode.
Steep sites and old houses. A lot of Karori, Mt Victoria, Kelburn and Aro Valley homes are over 100 years old with original earthenware lay — and they're often on slopes where access for excavators is a real planning exercise. CCTV before quoting is non-negotiable on these jobs.
Wellington City is part of the patch — but the Hutt Valley is home base.
Home turf — Trentham, Heretaunga, Silverstream, Te Marua, Wallaceville and Pinehaven.
