Redwood was drained swamp and farmland until the late 1950s, when rural sections began to be subdivided for houses. It grew rapidly from the 1970s, and further subdivisions followed in the 2000s with Regent's Park in the north-west and Redwood Springs in the north-east. We start every leak detection job in Redwood with a simple meter and pressure test, then use listening gear and a thermal camera to pinpoint the leak so only a small area needs opening.
Redwood leak detection on former swamp land
Before it was drained for farming, Redwood was raupÅ swamp and marsh, and the suburb only began to be subdivided from the late 1950s. Most homes date from the 1970s onward, with Regent's Park and Redwood Springs added in the 2000s. That gives two common leak pictures. In the 1970s houses, an ageing supply pipe or a corroded fitting under a timber floor is typical. In the 2000s homes, pipe is more often hidden in concrete slabs and walls.
Low, formerly wet ground can make a leak harder to spot from the surface. Soil that holds moisture may already look damp after rain, so a soggy patch does not prove a broken pipe, and a leaking pipe may not show at all. We rely on the meter first, with every tap off, and then pressure test individual lines to prove which one is losing water before any listening or digging. Ground that was once swamp can settle unevenly, which puts strain on buried joints over the years.
On slab homes in the newer streets, thermal imaging finds hot water lines leaking in the floor by the heat they spread, and acoustic gear picks up cold leaks under pressure. Frost also settles on Redwood's flat streets on calm nights, so we check pipes in garages and along outside walls for splits. We aim for one small access hole and give you a price before the repair.
Local tip: If you are in a 1970s Redwood home, ask us to check the condition of the line from the toby while we are there, because original pipe of that age is the usual weak point.
Leak Detection in Redwood: Local Factors
Homes from this era commonly have early plastic or copper pipe that develops leaks at fittings. We check the subfloor and walls to find the source.

Leak Detection Redwood FAQs
Can you find a leak under the slab of our Redwood Springs home without digging up the floor?
Usually. We pressure test the lines in the slab, then use thermal imaging and listening gear to find the spot, so the repair needs only a small opening.
Who is responsible for a leak at my Redwood property?
In Christchurch City the council looks after the pipe up to your boundary and the toby box, and you look after the supply pipe from the boundary into the house. Selwyn and Waimakariri set their own rules, so we check them for your address.
Can you find leaks under concrete slabs?
Yes. We use pressure testing and listening gear to locate leaks under slabs.
