Condensation Surveys in Cardiff
Independent condensation surveys across Cardiff. We measure humidity, surface temperatures and ventilation performance to diagnose condensation properly, not just sell a fan.
Independent, evidence-based surveys
Most 'damp' problems in Cardiff homes are actually condensation. A proper condensation survey measures relative humidity, surface temperatures and ventilation rates to confirm the cause before recommending any work.
Our independent condensation survey Cardiff service uses hygrometer logging, thermal imaging and ventilation checks to find cold bridges, ventilation failures and lifestyle drivers.
Because we don't sell PIV units, extract fans or insulation work, our report is unbiased and based purely on the data.
Common condensation issues in Cardiff properties
Victorian terraces
Solid-wall properties in Cathays and Roath have cold internal surfaces that condense moisture in winter.
Modern flats
Cardiff Bay apartments are airtight, ventilation failures push humidity straight onto cold surfaces.
Bathroom & kitchen moisture
Underspecified extract fans let moist air migrate to bedrooms and reception rooms.
Cold bridges
Failed cavity wall insulation creates cold spots where condensation forms in patterns.
Window condensation
Older glazing in inner-city properties produces heavy frame and sill condensation.
Drying laundry indoors
Without ventilation, indoor drying overwhelms even good extract systems.

Why independent surveys matter
We don't sell treatments, chemicals, or remedial work. That means our only job is to find the truth and explain it to you clearly.
We don't sell PIV units, extract fans, ventilation systems or insulation.
Every finding is supported by hygrometer logs, surface temperatures and photographs.
Where the answer is a £150 fan or a habit change, we'll tell you, not push £3,000 of equipment.
