Mold Inspection Course

Lesson 1 • Common Mould Genera in Buildings

Profiles Cladosporium, Penicillium, Aspergillus, Stachybotrys, and other frequently encountered genera. Connects morphology to inspection significance.

Lesson 2 • Mould Growth Requirements

Covers the four essential growth factors: moisture, temperature, nutrients, and oxygen. Understanding these factors enables inspectors to predict and locate mould growth.

Lesson 3 • Mould Spore Dispersal and Colonisation

Explains how spores travel via air, water, and contact, then colonise new substrates. Informs sampling strategy and contamination pathway analysis.

Lesson 4 • Health Effects of Mould Exposure

Summarises allergenic, irritant, and toxigenic health effects linked to mould exposure. Establishes the public health rationale for thorough inspection practice.

Lesson 1 • Moisture Intrusion Pathways

Identifies bulk water entry, capillary action, and air-transported moisture as the three primary intrusion modes. Connects each pathway to specific building failure points.

Lesson 2 • Building Materials and Moisture Retention

Compares moisture absorption and drying capacity of common substrates including drywall, wood, and concrete. Guides substrate-specific risk assessment during inspections.

Lesson 3 • Condensation and Thermal Bridging

Explains interstitial and surface condensation caused by thermal bridges and inadequate insulation. Prepares inspectors to identify hidden moisture accumulation zones.

Lesson 4 • HVAC Systems and Moisture

Examines how heating, cooling, and ventilation systems generate, distribute, or control moisture. Inspectors learn to evaluate HVAC as both a mould source and a control tool.

Lesson 1 • Defining Inspection Scope and Objectives

Establishes how to gather client history, define inspection boundaries, and set measurable objectives. A clear scope prevents missed areas and scope creep.

Lesson 2 • Personal Protective Equipment Selection

Covers respirator classes, glove types, eye protection, and protective clothing appropriate to mould exposure levels. Correct PPE selection prevents inspector health risk.

Lesson 3 • Regulatory and Professional Standards

Surveys applicable occupational health standards, indoor air quality guidelines, and professional codes of practice. Inspectors align their methods with recognised benchmarks.

Lesson 4 • Inspection Equipment Preparation

Details calibration, maintenance, and staging of all inspection tools prior to site arrival. Properly prepared equipment ensures accurate data collection from the first measurement.

Lesson 1 • Recognising Mould Visual Indicators

Trains inspectors to distinguish active mould growth, staining, and biofilm from non-mould discolouration. Accurate visual identification reduces unnecessary sampling costs.

Lesson 2 • Moisture Damage Pattern Recognition

Covers water stains, efflorescence, paint bubbling, warping, and rust as moisture damage indicators. Pattern recognition links visible damage to underlying moisture sources.

Lesson 3 • Systematic Room-by-Room Protocol

Introduces a structured inspection sequence covering exterior, interior, attic, crawlspace, and basement zones. Systematic sequencing eliminates missed areas and ensures reproducibility.

Lesson 4 • Photographic Documentation Standards

Establishes protocols for capturing orientation, close-up, and scale-referenced photographs. Consistent photo documentation supports report writing and client communication.

Lesson 1 • Integrating Multi-Instrument Data

Teaches how to correlate readings from multiple instruments to build a coherent moisture map. Integrated data reduces false positives and strengthens inspection conclusions.

Lesson 2 • Borescopes and Probing Tools

Introduces borescopes, probes, and wall cavity access tools for minimally invasive investigation. These tools confirm hidden mould or moisture without full demolition.

Lesson 3 • Thermal Imaging for Moisture Detection

Explains infrared thermography principles and how thermal anomalies indicate moisture and insulation defects. Inspectors learn to distinguish thermal patterns from mould-unrelated causes.

Lesson 4 • Pin and Pinless Moisture Meters

Compares pin-type and pinless moisture meters, covering operating principles, calibration, and substrate correction factors. Correct meter selection prevents false readings.

Lesson 1 • Sampling Strategy and Decision Logic

Establishes when sampling adds value beyond visual inspection and how to design a statistically sound sampling plan. Strategy decisions directly affect result reliability.

Lesson 2 • Air Sampling Techniques

Covers spore trap, impactor, and cassette air sampling methods, including pump calibration and sample volume. Correct technique ensures representative airborne spore counts.

Lesson 3 • Surface Sampling Techniques

Details tape lift, swab, and contact plate methods for collecting surface mould samples. Each method suits different surface types and analytical goals.

Lesson 4 • Bulk and Dust Sampling

Explains collection of building material fragments and settled dust for mycological analysis. Bulk samples provide substrate-level contamination data unavailable from air sampling.

Lesson 1 • Understanding Laboratory Report Formats

Explains spore count units, analytical methods, and quality control indicators found in lab reports. Familiarity with report structure prevents misinterpretation of results.

Lesson 2 • Interpreting Surface and Bulk Results

Covers qualitative and semi-quantitative interpretation of surface and bulk sample findings. Results are linked back to visual findings and moisture data for context.

Lesson 3 • Identifying False Positives and Negatives

Addresses sampling errors, background contamination, and analytical limitations that produce misleading results. Inspectors learn to flag and address data quality issues.

Lesson 4 • Comparing Indoor and Outdoor Spore Levels

Teaches the indoor-to-outdoor ratio method and its limitations for evaluating contamination significance. Correct comparison prevents both over- and under-reaction to results.

Lesson 1 • Communicating with Clients and Stakeholders

Develops skills for presenting findings verbally and in writing to property owners, tenants, and contractors. Clear communication prevents misunderstanding and supports informed decisions.

Lesson 2 • Inspection Report Structure and Standards

Defines required report sections: scope, methods, findings, conclusions, and recommendations. A standardised structure ensures completeness and professional credibility.

Lesson 3 • Writing Remediation Recommendations

Explains how to recommend containment, removal, drying, and post-remediation verification based on contamination level. Recommendations must be specific, prioritised, and feasible.

Lesson 4 • Report Quality Control and Review

Establishes a self-review checklist and peer-review process to catch errors before report delivery. Quality control protects professional reputation and reduces liability exposure.
