Scientific Condensation & Mould Surveys
Persistent black mould (Aspergillus niger) is a serious hazard to respiratory health, yet landlords and contractors routinely claim it's "lifestyle condensation issues." We provide scientific, independent moisture and ventilation mapping to isolate the real diagnostic root causes of indoor dampness.
Our Scientific Indoor Climate Diagnostics Include:
Dew Point Mapping
We combine thermodynamic relative humidity checks with surface temperatures using laser thermometers to determine precisely where wall temperatures fall below the local dew point.
Fan Extraction Flow-Rate Testing
We measure the physical volumetric extraction rates (litres per second) of kitchen and bathroom extractors using professional anemometers to verify compliance with Part F of Building Regulations.
Thermal Cold Bridging Inspections
High-resolution thermal camera scans reveal missed insulation layers, lintel cold pockets, or cavity bridge stones that create persistent, damp condensation spots inside rooms.
Sub-Floor Mechanical Ventilation reviews
Blocked air vents beneath suspended timber floors cause damp stagnation, which quickly climbs internal walls and causes mould blooms behind skirting boards.
Curing Mould Permanently (No Spray "Cover Up" Tricks)
Wiping masonry or wallpaper with bleach or toxic mould sprays provides only a temporary aesthetic improvement. If the relative surface humidity index exceeds 70%, fungal spores germinate and returns within weeks. Curing black mould permanently requires resolving the physical damp source (bridged cavity walls, roof leaking, gutters overflowing) or establishing adequate, constant domestic air exchanges (such as trickling window vents or positive input ventilation systems). Our diagnostic reports give you the exact technical adjustments required.
Condensation & Mould FAQ
What is PIV, and can it eliminate mould?
Yes, Positive Input Ventilation (PIV) is highly effective. Mounted in the loft, it pumps dry, filtered air throughout the central hallway, creating a slight positive atmospheric pressure that forces damp-laden air out of window extractors or brick joints, keeping humidity levels below spores germination points.
Why does mould grow behind wardrobes on external walls?
External walls are colder. Heavy wooden wardrobes block heated room air from circulating against the wall surface, trapping stagnant, moisture-heavy air behind, which drops below the dew point, creating damp condensates perfect for Aspergillus mould growth.
