The science
How structural drying actually works
Drying is a science of vapour pressure. We engineer a low-vapour-pressure environment that pulls moisture out of saturated materials — fast enough to beat the 24–48 hour mould window.
Vapour-pressure differential
High vapour pressure inside wet materials migrates to the lower vapour pressure of dehumidified air. We control air movement, dehumidifier capacity and temperature to keep that gradient steep — that's how a slab that would air-dry in months goes to spec in days.
Step 01
Water extraction
Truck-mounts, flood pumpers and portable extractors remove free water within hours of arrival.
Step 02
Moisture detection
Pin and pinless moisture meters plus thermal cameras locate hidden moisture in cavities and subfloors.
Step 03
Air movement
High-velocity air movers create vapour-pressure differentials that drive moisture out of materials.
Step 04
Dehumidification
LGR and desiccant dehumidifiers capture water vapour before it can condense or feed mould.
Step 05
Heat drying
Targeted heat drying systems accelerate evaporation in dense substrates like concrete and double subfloors.
Step 06
Verification
We confirm dry standard with documented moisture readings and provide a full report for your inspector or insurer.

How we work
How we work with builders
A drying programme that lives inside your build programme — not bolted on at the end.
Programme review
We look at your build sequence and pick the right drying windows — slab, post-lining, pre-paint, pre-floor.
Fixed quote
Written quote with cubic-volume calc, equipment list, drying days and target moisture content per substrate.
On-site delivery
Equipment delivered and commissioned by our technician. Daily moisture logs uploaded to your foreman.
Trade-ready sign-off
Signed report at each milestone — proof for the BCA, the flooring sub, the painter and your insurer.
Why Christchurch builders choose us

Christchurch owned and run since 2023. We work with group home builders, custom builders, renovators and main contractors.
Right-sized equipment
LGR + desiccant fleet sized to actual cubic volume — never under-spec'd, never billing for kit that isn't earning.
Liability protection
Documented pre-line and pre-floor moisture is your insurance against future weathertightness and warranty claims.

What builders say
On the tools, not on the sidelines
Trusted by Christchurch's most-respected house builders and renovators.
"We had a slab sitting at 88% RH two weeks before our flooring guy was due in. PrestigePro Dry Build came in, ran the numbers, set up the kit and had it under 75% in five days. Saved the programme."
"I run a small renovation crew. These guys are the only sub I trust to call my clients direct — they never up-sell, never try to take work off me. Honest moisture readings, signed reports, on to the next."
"Their pre-line E2 moisture reports have been accepted by every CCC inspector we've seen. Cheaper than the cost of one weathertightness claim, and the paperwork is bulletproof."

FAQ
Builder & client FAQs
Do you only work with builders, or with homeowners too?
Our main client base is Christchurch house builders and renovators, but we also help homeowners directly — particularly when they're managing their own renovation or dealing with a leak before the builder is on site.
How fast can you mobilise a drying setup on a Christchurch site?
Same-day for emergencies, next-business-day for scheduled jobs across Christchurch, Selwyn and Waimakariri. Repeat trade clients get priority dispatch.
Do you provide moisture reports for council inspections?
Yes — our NZBC E2/AS1 moisture verification reports are accepted by Christchurch City Council, Selwyn District Council and Waimakariri District Council building inspectors.
What does structural drying cost on a typical new build?
Costs scale with cubic volume, target moisture and drying urgency. Most domestic new-build drying programmes sit between $1,800 and $6,500 + GST. We quote fixed before mobilising.
