Case Studies

Customer reports from real visits — focused on the property type, what residents experienced, and what was wrong.

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
Semi-Detached • B34

Low skirting damp patch

Customer report: “Small patch keeps staining near the skirting — worried it’s rising damp.”

Property type: 3-bed semi

What was wrong: Localised external splashback from a minor rainwater issue; non-systemic internal salts signature. Not consistent with widespread rising damp.

“Helpful to understand it wasn’t a full damp problem.”— Homeowner
HMO • B12

Shared bathroom mould

Customer report: “Mould returns on the ceiling and grout in the shared bathroom.”

Property type: Multi-occupancy house

What was wrong: High moisture load from frequent showers; extractor overrun too short; door routinely left open leading to moisture drift into cooler areas.

“Clear explanation of why it kept appearing.”— Landlord
Top-Floor Flat • B3

Ceiling staining after storms

Customer report: “Brown marks around a light fitting after heavy rain.”

Property type: 2-bed flat (top floor)

What was wrong: Intermittent weather-driven ingress at roof interface; symptoms consistent with wind-directed rainfall and lifted flashing risk.

“Identified the weather pattern and location risk.”— Agent
