Services
Airtightness and moisture risk in residential buildings are examined through onsite visits and analysis.
Airtightness and Leakage Diagnostics
Airtightness and leakage are assessed using an on-site blower door test combined with diagnostic thermal imaging to locate infiltration through the building envelope.
When this is used
-
during construction, prior to internal linings and at lock-up
-
in buildings where mould and condensation are visible or suspected
-
prior to, during or following, retrofit and remediation work
What you receive
-
pre-inspection review of plans
-
2-hour site visit
-
blower door testing to measure airtightness (ACH₅₀)
-
thermal imaging to identify leakage paths
-
a concise report including airtightness results, documented leakage locations, and practical recommendations
Fees
Airtightness and leakage diagnostics are typically $1,100 (ex GST), with adjustments for building size or complexity.
Service Area
This service is provided in Tasmania and the Melbourne metropolitan area. Travel fees may apply.
Moisture, Condensation and Mould Risk
Assessment of moisture related issues considering air movement, surface temperatures, insulation continuity, ventilation, and occupant use patterns in a cohesive study - together, rather than in isolation.
When this is used
-
mould or condensation is visible or suspected
-
occupant discomfort is linked to high internal humidity
-
recent changes have been made to insulation, airtightness, ventilation, or heating systems
What you receive
-
pre-inspection review of available plans, including orientation and site context
-
on-site inspection
-
examination of relevant areas using thermal imaging
-
assessment of insulation continuity in areas affected by mould or condensation
-
a concise report documenting observations, identified contributing factors, and practical recommendations
Fees
Fees are scoped per project and depend on building size, complexity, and the location of moisture-affected areas. Additional contractors may be required where access to interstitial spaces is necessary.

Hygrothermal (WUFI) Risk Assessment
Hygrothermal simulations are not a compliance check and do not guarantee performance. They are used to understand the behaviour of moisture under defined assumptions.
WUFI Pro is used to simulate heat and moisture movement within specific building assemblies using climate data for the project location. This allows areas of potential condensation and mould growth to be identified where behaviour cannot be confidently inferred from precedent alone.
When this is used
- assemblies are non-standard
- moisture behaviour is uncertain
- alternative wall, roof, or floor assemblies are being compared
What you receive
- a concise report presenting modelling results showing the location and extent of potential condensation and mould risk within the simulated assembly
- a clear statement of assumptions and limitations used in the modelling
Fees
Fees are quoted after review of the relevant drawings and confirmation that hygrothermal simulation is appropriate for the project.

This service can be performed remotely.
