Condensation Surveys in South Wales
Independent condensation survey Wales service across Bridgend, Cardiff, Swansea, Newport and beyond. We find the real cause of condensation, streaming windows and mould so the problem can finally be solved.
Independent, evidence-based surveys
Most 'damp' problems reported in South Wales homes are actually condensation. Streaming windows, mould around frames, musty bedrooms and black spots on ceilings usually point to a humidity, ventilation or thermal-bridging issue, not rising damp.
Our condensation survey Wales service measures internal humidity, surface temperatures, ventilation performance and external defects to pinpoint why condensation is forming in your specific property. It's an independent property survey South Wales homeowners can rely on.
Because we don't sell extractor fans, PIV units or insulation, our recommendations are tied to your property's actual conditions, not a product range.
Common condensation issues in South Wales homes
Streaming windows
Heavy morning condensation pooling on sills is usually a humidity and ventilation imbalance.
Bedroom mould
Cold external corners and behind-wardrobe mould patches are a classic South Wales winter pattern.
Bathroom & kitchen humidity
Extractor fans that are weak, blocked or vented into the loft simply move the problem.
Modern airtight homes
New builds across South Wales seal in moisture without enough ventilation to remove it.
Cold solid-wall properties
Older Welsh terraces have cold internal surfaces that act as natural condensation traps.
PIV units installed incorrectly
Positive input ventilation is often mis-sized or wrongly positioned, masking rather than fixing the issue.

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 are not a ventilation installer or damp-proofing company. Our condensation survey Wales reports recommend solutions based on the evidence in your home.
Mis-diagnosed condensation costs South Wales homeowners thousands in unnecessary damp-proofing every year. An independent report avoids that risk.
Reports use measured data, humidity, surface temperature, dew point, so any contractor you appoint has a clear, evidence-backed brief to work from.
