Halswell began as a separate village and was joined to the city by successive subdivisions: Oaklands in the 1960s, Westlake in the late 1980s and Aidanfield in the 1990s. Since the 2011 earthquakes it has grown rapidly, with Longhurst and Knights Stream developed to the west. The Rocks subdivision sits on the Port Hills at the top of Kennedys Bush Road, while the rest of Halswell is on the flat Canterbury Plains. We start every leak detection job in Halswell 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.
Halswell's newer subdivisions and leaks inside the slab
Halswell has grown in waves, from 1960s Oaklands through Westlake and Aidanfield to the newer Longhurst and Knights Stream developments west of the old village. A large share of its homes are slab-on-ground houses with plastic pipe running inside concrete and walls. When one of those lines leaks, nothing appears for a while; the first sign might be a warm spot on tiles, a damp carpet edge or a bigger water charge.
We start with the meter and then split the system into hot and cold and inside and out. Hot water leaks in slabs show up well on a thermal camera because the escaping water warms the concrete around it. Cold water leaks are found with acoustic gear and a pressure test on each line. The goal is a small hole above the leak rather than lifting floors in a near-new home.
Older Oaklands homes are more likely to have timber floors and original supply pipe from the boundary, so the search there looks more like one in an older suburb. Hillside homes at The Rocks, above Kennedys Bush Road, can have long, steep supply runs. Parts of Halswell use individual property pump stations for wastewater, which are separate from your water supply but worth mentioning when you book. Westlake and Aidanfield homes from the late 1980s and 1990s sit between the two, so we confirm the floor type and pipe material before choosing the gear.
Local tip: In a newer Halswell home, walk the floors barefoot on a cold morning; a warm patch that is not near a heat pump can be a hot water leak in the slab.

Leak Detection Halswell FAQs
Our Knights Stream home has a warm patch on the kitchen tiles. Does that mean a leak?
A warm patch with no heater nearby often points to a hot water line leaking in the slab. We isolate the hot side, pressure test it and use thermal imaging to find the spot.
How do I check for a leak myself?
Turn off every tap and watch the meter at the toby. If it keeps moving, there may be a leak.
How much does leak detection cost in Halswell?
The repair is priced separately once we know where the leak is.
