If you’ve got mould, wet windows, musty smells, or damp corners — you need evidence, not guesswork. Our condensation reports confirm what’s happening using measured humidity, dew point analysis and clear on-site findings.
Perfect for homeowners, landlords, tenants, letting agents, and property managers who need a written assessment to prove cause, stop repeat callouts, and fix the issue properly.
Book a Condensation Risk Assessment and get a clear report covering moisture behaviour, ventilation, cold bridging indicators, and practical fixes to reduce mould risk.
Because “wipe it down” and “open a window” isn’t a strategy. Evidence matters.
We record temperature, relative humidity and calculate dew point to assess whether conditions are conducive to surface condensation.
Extractor performance, background ventilation, trickle vents, airflow limitations and typical moisture production are considered properly.
Clear steps that actually help: airflow improvements, heating strategy, insulation/bridging considerations, and moisture reduction measures.
Thermal imaging highlights cold spots and suspected bridging patterns where mould commonly appears first (corners, reveals, ceilings, junctions).
A structured report that explains mechanisms clearly, documents findings, and helps prevent the same argument happening again next winter.
Condensation doesn’t exist in isolation. We consider building fabric, defects, airflow and heat loss so causes aren’t mislabelled as “damp”.
A systematic check of moisture behaviour, environment and building factors.
We discuss where mould or moisture shows (corners, window reveals, ceilings, behind furniture) and when it worsens (cold snaps, after showers, overnight).
We measure indoor conditions (temperature and RH) and calculate dew point to assess the likelihood of surface condensation at the time of inspection.
Extractor fans, background ventilation, occupancy factors and moisture sources (drying clothes, unvented bathrooms, kitchens) are reviewed realistically.
Thermal imaging highlights cooler zones that commonly correlate with mould/condensation risk, including thermal bridging and heat-loss patterns.
Where relevant, we check for obvious external factors that can mimic condensation (leaks, failed sealants, gutters, bridging, saturated materials).
You receive a clear condensation report with findings, evidence, and practical recommendations to reduce mould risk and stabilise internal conditions.
Condensation is about air moisture meeting cold surfaces. We prove the conditions, then fix the reasons.
We record internal air conditions and explain what those readings mean in real terms:
Thermal imaging helps identify cooler zones that can promote condensation and mould:
Real clarity beats repeat mould treatments every time.
"We kept cleaning mould and it kept coming back. The report explained the real cause and what to change. It finally stopped."
"As a landlord, having a written condensation risk assessment made everything clear. It helped resolve a dispute quickly."
"Thermal imaging showed exactly where the cold spots were. We improved ventilation and it made a massive difference."
A condensation report (condensation risk assessment) documents humidity, dew point conditions and contributing factors such as ventilation, cold bridging and moisture load. It explains the likely mechanism and gives a clear action plan to reduce mould risk.
No. Mould often aligns with condensation risk, but leaks, penetrating damp and bridged materials can mimic it. We assess the full context to avoid the wrong conclusion.
Yes. We look at real-world airflow, typical moisture production, and practical improvements. Where relevant, we highlight weak points like poor extraction, blocked vents and limited background ventilation.
Written reports are typically delivered within 48 hours of inspection, depending on scope and workload.
We cover Pembrokeshire, Carmarthenshire, Ceredigion, Swansea, Cardiff and surrounding areas. View coverage.
