Northwood is one of Christchurch's newest suburbs, developed from 2000 as a subdivision of Belfast on land that was previously apple orchards. The wider Belfast area saw only minor liquefaction and little damage in the Canterbury earthquakes. We start every leak detection job in Northwood 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.
Northwood's orchard-era subdivision and the leaks newer homes get
Northwood was developed from 2000 on land that had been apple orchards, so almost every home is from the last quarter century. Leaks here are seldom about corroded old pipe. They are more often a fitting behind a shower, a joint on a hot line in a slab, or a connection disturbed during building or a later renovation. Those leaks hide inside concrete and framing, and the first clue is usually a damp skirting, a musty wardrobe or an unexplained excess water charge.
We begin with the meter and isolate the hot and cold systems. If the hot side is losing water, thermal imaging usually shows a warm trail across the floor. On the cold side, an acoustic microphone on the slab picks up the hiss. Once we have the spot, the aim is a small, neat opening, which matters in a modern home where tiles and flooring are expensive to replace and hard to match.
Northwood sits on the open plains near Styx Mill Reserve and The Groynes, and calm winter nights bring hard frosts. Outdoor taps, garden irrigation connections and pipes in garages are the parts most exposed, and a frozen fitting can crack without any sign until it thaws. The wider Belfast area had only minor liquefaction, so ground movement is rarely the cause of a leak here.
Local tip: In a Northwood home, a musty smell in a wardrobe that backs onto a bathroom is worth a leak test before the board swells.
Leak Detection in Northwood: Local Factors
Frost can split pipes in garages, roof spaces and under floors, and the leak may only show once the pipe thaws. We find it and recommend lagging for exposed runs.

Leak Detection Northwood FAQs
Our Northwood house is about 20 years old. Is a leak likely to be under the slab?
It could be under the slab, but in homes of this age many leaks are at shower and tap fittings inside walls. We test both systems first, which tells us whether to search the floor or the walls.
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 Northwood?
The repair is priced separately once we know where the leak is.
