A report that actually answers the question.
Every survey produces a plain-English report covering sampling methodology, laboratory results, building observations and prioritised action — suitable for repairs, insurance claims and tribunal cases alike.
"Mould is a moisture problem before it is a fungal problem. Identify the species, then follow the water — that is what a defensible report does."

№ 04 — Why Mould Testing Matters
Mould is common in UK buildings. The answer is evidence, not panic.
Damp and mould affect a significant share of UK housing stock and a meaningful slice of the country's office, school and healthcare buildings. The Homes (Fitness for Human Habitation) Act 2018, the Social Housing (Regulation) Act and the Awaab's Law framework have raised the bar for how landlords and housing providers must respond when occupants report visible mould, musty smells or related symptoms.
Behind every mould complaint is a moisture mechanism — condensation on a cold surface, penetrating damp through a failed render or flashing, rising damp through a defective damp-proof course, a leak from plumbing or rainwater goods, or construction moisture trapped in a recently built or refurbished property. Treating the visible patch without identifying that mechanism guarantees recurrence.
Mould air testing and spore testing quantify what is actually airborne. On-site inspection records the building context. Damp and mould surveys diagnose the moisture mechanism. Water-damage testing verifies safe re-occupation after leaks and floods. Each service produces evidence that holds up with builders, insurers, housing officers and tribunals.
We are deliberately non-alarmist. We do not use "toxic mould" language where the evidence does not support it, and we do not make medical claims that belong to a clinician. We report what the sampling and inspection show, in language that the people who need to act on it can use.
