Underslab Plumbing Done Right, the First Time

Underslab plumbing forms the foundation of a building’s water supply and drainage, and it needs to be right before the concrete goes down. JD’s Plumbing has the expertise to handle underslab plumbing installation, repair, and maintenance for both residential and commercial builds across Auckland, Otago, and Northland. Getting this stage wrong can mean costly rework later, so we take the time to get pipe placement, gradients, and connections correct from the start.

Specialist Repairs Without Unnecessary Disruption

If there’s a suspected issue with existing underslab plumbing, our team can diagnose the problem accurately before recommending a repair approach, avoiding unnecessary excavation or cost where possible.

Frequently Asked Questions

What is underslab plumbing?

Underslab plumbing refers to the water supply and drainage pipework installed beneath a concrete slab, usually before a building’s foundation is poured. It needs to be planned and installed correctly since it’s difficult to access once the slab is down.
Cost depends on the extent of the issue and whether excavation is required. We assess each situation individually and provide an upfront quote before starting work.
We use diagnostic techniques to narrow down the likely location of a leak before any excavation, helping to minimise disruption and cost.

Jared and his team are amazing! We had our bathroom fully revamped by his team, at first we didn’t know what we wanted. So jared came around and helped us decide. The 2 guys that came in and changed the bathroom were really easy to work with. Great communication between everyone. Would highly recommend Jds plumbing and will definitely be calling Jared in future
