Moisture Testing Auckland
Know exactly where the moisture is.
Hidden moisture is the kind that does the damage, quietly, behind the wall, long before it shows. A Datum moisture test works through every area water gets into and collects in, with non invasive meters, then hands you a mapped, photographed report the same day, so you know exactly where the water is and how much it matters. Moisture testing is included in every full Datum building inspection.
Water you cannot see is the kind that does the damage.
The leaks that matter rarely announce themselves. By the time a stain shows on the ceiling or a skirting feels soft, water has often been getting in for months, quietly feeding rot, mould and, in the wrong house, a weathertightness problem.
Moisture testing finds it while it is still a reading on a meter, not a repair bill. Caught early it is a fix. Caught late it can be the framing.
Where water hides, and where we look.
Moisture testing is about the places water gets in and the places it collects, most of them out of sight. This is where we test.
Wet areas
Bathrooms, kitchens and laundries, and the walls and floors around showers, baths and sinks, where a leak starts small and spreads unseen.
Windows and joinery
Reveals, sills and the junctions around windows and doors, a classic way for water to get in and show up inside as a stain long after.
Cladding and weathertightness
The junctions, penetrations and details on the cladding, with extra attention on the plaster and monolithic homes the leaky building era left behind.
Subfloor and base
Under the floor, where rising damp, poor ventilation and ground moisture build up out of sight and feed rot in the timber above.
Ceilings and roof space
Ceilings under wet rooms and around roof penetrations, where a slow roof or plumbing leak first shows as a darkening patch.
The reading
Non invasive meters first, probes where they are warranted, every reading mapped, photographed and explained, so a number on a wall actually means something.
What a moisture test covers, and what it does not.
Moisture testing is included in every Datum building inspection. This page is for when you want the moisture check on its own. Either way, here is what it does, and where it stops.
In every moisture test
- Non invasive moisture readings across every at risk area
- Targeted probe readings where a surface reading warrants it
- Wet areas, windows, cladding, subfloor and ceilings all checked
- A report with the readings, where they were taken, and what they mean
- Photos of every area of concern, in plain English
- Same day delivery by 6pm, and a call to walk you through it
Where we draw the line
- Non invasive meters read moisture at and just below the surface, not deep inside a sealed cavity, and we flag where that needs opening up
- We do not remove linings, cut into walls or lift floors
- Readings are a snapshot of the day, and moisture moves with the weather
- This is a focused moisture test, not a full building inspection
- For a heat map across a whole elevation, thermal imaging is the deeper tool, and a separate service
A reading you can actually act on.
A moisture meter on its own just beeps. A number with no map and no interpretation tells you nothing about whether you have a problem.
Ours takes a position. Every reading is placed, photographed and called, normal, elevated or wet, so you know exactly where the moisture is and how much it matters. Booked before 10am, it is in your inbox by 6pm.
From $249, shown before you book.
What is included
- Non invasive readings across every at risk area
- Probe readings where they are warranted
- A mapped, photographed report with what each reading means
- Delivered the same day, by 6pm

Book a moisture testA moisture reading is only as useful as the person taking it.
Anyone can buy a moisture meter and wave it at a wall. Whether the reading means anything depends on testing the right places, in the right way, and knowing what normal looks like for that material and that day.
Every Datum moisture test is mapped, photographed and interpreted, so you get a clear read on where the water is and what it means, not a list of numbers you have to guess at.

Auckland is built for moisture problems.
A warm, humid, high rainfall climate, a lot of plaster and monolithic homes from the leaky building era, and clay ground that holds water. Auckland has the full set of conditions that let moisture take hold, and most of it works away unseen until it is expensive. The plaster and monolithic clad homes of the late 1990s and 2000s are the ones we test hardest, because their cladding junctions are exactly where that era is known to let water in.
Moisture testing, answered.
A focused check for hidden moisture in a property, using meters to find water in walls, floors, ceilings and the areas around windows and wet rooms, before it shows up as a stain or soft timber. You get a report that maps every reading and says what it means.
If you are getting a full building inspection, moisture testing is already included in it, so you may not need this as well. A standalone moisture test is for when you have a specific concern, a stain, a smell, a patch you can feel, or a known weathertightness risk, and you want the moisture check on its own.
Yes. Moisture testing is included in every full Datum building inspection. This page is the standalone service for when a full inspection is not what you need.
We start with non invasive meters that read moisture through the surface, so nothing is damaged. Where a reading warrants it, we use a probe for a more precise figure. Every reading is placed on a map of the property and photographed.
Non invasive meters read moisture at and just below the surface, so they show where water is present without opening anything up. Where a reading suggests water deeper in the cavity, we flag exactly where it needs investigating further. We do not cut into walls or remove linings.
Moisture meters measure moisture content directly, at a point on a surface. Thermal imaging reads temperature across a whole area, which can reveal hidden damp, gaps and missing insulation that a single reading would miss. They work well together, and thermal imaging is a separate, deeper service.
Homes clad in plaster or monolithic systems through the late 1990s and 2000s are the ones most associated with weathertightness problems in New Zealand. It does not mean yours has one, but the cladding junctions are exactly where targeted moisture testing earns its keep.
From $249 as a standalone test, with the full price shown before you book and varying with the size of the property. If you book a full building inspection, moisture testing is included at no extra charge.
