HMO • Student Flat • B5
Recurring bedroom mould
Customer report: “Black mould keeps returning on the outside corner wall. Worse in the mornings.”
Property type: 5-bed HMO (student let)
What was wrong: Overnight humidity consistently high; cold external corner (thermal bridging typical of construction). Window trickle vents closed; bathroom extractor underused.
“The report explained why it kept coming back without guessing.”— Tenant lead
Victorian Terrace • B29
Damp patch by staircase
Customer report: “Paint bubbling and musty smell near the stairs. Thought it might be a pipe leak.”
Property type: 3-bed terrace
What was wrong: Localised penetrating damp from weather exposure — failed pointing and rainwater discharging onto masonry. Internal salts pattern supported external ingress.
“Pinpointed the source so we knew what we were dealing with.”— Owner
New-Build Apartment • B1
Condensation on window reveals
Customer report: “Water beads on the reveals most mornings; occasional mould dots.”
Property type: 1-bed flat
What was wrong: Evening/everyday humidity elevated from cooking and occupancy; low fresh air provision (vents closed). Condensation formed at cold reveal edges.
“Made sense of the readings and the pattern we were seeing.”— Resident
