Drainlayers Wellington — Your Job On Time, Or It’s Free
Southern’s drainlayers have been digging, clearing, relining and replacing Wellington drains since 1982. 40+ years, around 29,000 jobs, every suburb from Seatoun to the Kapiti Coast. Fixed-price quotes before we start. And if we don’t turn up when we said we would — you don’t pay.
Phone 0800 484 353 for fast response across Wellington, the Hutt Valley, Porirua and Kapiti.
Every Drainage Service Under One Roof
We own all the kit — excavators, CCTV rigs, hydro-jets, pipe-reline equipment. One company, one invoice, one point of contact:
- New drain laying for renovations, extensions and new builds
- Sump, gully trap, and drain pit replacement
- Stormwater line repairs and soakpits
- Sewer line replacement (house-to-boundary)
- Basement seepage and ground-water drainage
- CCTV drain inspection with USB footage
- Drain unblocking — mechanical, water-blast, hydro-jet
- Septic tank servicing and pump-out
- Pipe relining (no-dig repairs)
- Drainage investigations and dye testing
Built for Wellington’s Terrain
Wellington drainage is harder than most cities. Steep sections in Karori and Khandallah, reactive clay soils in Island Bay, rock in Seatoun, high water tables along the Hutt River flats, seismic movement everywhere.
That’s why we’ve built a team that knows how to work it: mini excavators that fit Wellington driveways, tracked dumpers for wet sites, specialist no-dig relining rigs for heritage villas where you can’t trench. And a Certifying Drainlayer to sign off every job.
Fixed-Price Quotes, Council Sign-Off Included
Before we dig, you get a price in writing. That price is the price. No “we found another problem halfway through, that’s another $2,000”. If unknowns genuinely need to be investigated first (old pipes, unmapped services), we say so up front and charge a diagnostic fee — which is credited back if you proceed.
Every new drain is:
- Designed and laid to NZ Building Code
- Council-notified and inspected
- Pressure-tested before backfill
- CCTV-recorded as-built
- Covered by the Master Plumbers Guarantee
24/7 Emergency Drain Response
Sewage overflowing onto the lawn isn’t a “we’ll get to it next Tuesday” problem. Southern is open 24/7, every day of the year, including Christmas. When you call, a real person answers — not a pager service.
We keep drainlaying vans stationed across the region so response is fast: Wellington city, the Hutt Valley, Porirua, Kapiti, Wairarapa. Call 0800 484 353.
