Drainlayer Upper Hutt
Home turf — Trentham, Heretaunga, Silverstream, Te Marua, Wallaceville and Pinehaven.
View Upper Hutt →Double Dz Drainage covers Wellington City the same way we cover the Hutt — fixed quotes, qualified drainlayer, CCTV before we dig. We work 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.
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.
Targeted fixes. Cheaper than full re-lay where the camera shows it's worth it.
Council-spec stormwater pits sized to your section, soil type, and rainfall.
Full drainage scope for new Khandallah, Johnsonville and Karori builds.
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.
