Damp & Mould Surveys in South Wales – Don’t Treat the Symptoms, Find the Cause
Damp and mould are among the most common problems affecting homes and commercial buildings across South Wales. While many people assume a quick coat of anti-mould paint or a dehumidifier will solve the issue, these are often only temporary fixes. Unless the underlying cause is correctly identified, damp and mould will usually return – sometimes worse than before.
At Surveying Cymru, we specialise in professional, independent damp and mould surveys that identify the true cause of the problem. Rather than selling unnecessary treatments, we provide honest, evidence-based reports with practical recommendations that save property owners time, money and unnecessary disruption.
Why Damp & Mould Should Never Be Ignored
Damp isn’t simply an aesthetic issue. Left untreated, it can lead to:
- Mould growth affecting indoor air quality
- Damage to plaster, timber, decorations and flooring
- Rotting structural timbers
- Increased heating bills through heat loss
- Poor insulation performance
- Respiratory problems, particularly for children, the elderly and asthma sufferers
- Reduced property value
- Mortgage and homebuyer concerns
The earlier the cause is identified, the easier and often cheaper it is to rectify.
We Find the Cause – Not Just the Symptoms
One of the biggest misconceptions within the industry is that every damp problem is rising damp.
In reality, many properties suffering from damp are actually experiencing issues such as:
- Condensation caused by inadequate ventilation
- Cold bridging
- Penetrating damp
- Defective rainwater goods
- Plumbing leaks
- External masonry defects
- Failed pointing
- Cavity wall insulation defects
- Poor insulation
- Roof defects
- Blocked cavities
- Construction defects
Every building behaves differently.
Our surveys investigate the property as a complete system rather than simply testing one wall with a moisture meter.
What Our Damp & Mould Surveys Include
Every inspection is carried out methodically using professional surveying techniques.
Our surveys typically include:
✔ Full internal and external inspection
✔ Moisture profiling where appropriate
✔ Identification of moisture pathways
✔ Assessment of ventilation performance
✔ Thermal bridging observations
✔ Building defect identification
✔ Roof, guttering and external wall observations
✔ Cavity wall considerations
✔ High-resolution photographs
✔ Easy-to-understand written report
✔ Practical remedial recommendations
We explain exactly why the damp is occurring—not simply where it is.
Independent Advice You Can Trust
Unlike many damp companies, our surveys are completely independent.
We do not attend your property to sell chemical injections or unnecessary treatments.
Our only objective is to accurately diagnose the problem and provide honest recommendations based on the evidence found during the inspection.
This gives homeowners, landlords, letting agents, buyers and commercial clients confidence that they are receiving impartial professional advice.
Common Signs You Should Arrange a Damp Survey
You should consider arranging a professional damp and mould survey if you notice:
- Black mould around windows
- Peeling wallpaper
- Damp patches on walls or ceilings
- Musty smells
- Bubbling paint
- Salt deposits on walls
- Wet skirting boards
- Rotting timber
- Condensation running down windows
- Cold internal walls
- Persistent mould despite repeated cleaning
Ignoring these signs often allows the underlying issue to worsen over time.
Damp Surveys for Home Buyers
Buying a property is one of the biggest investments you’ll ever make.
If you’ve noticed damp during a viewing or your survey has highlighted possible moisture issues, we can provide a specialist damp inspection before you commit to the purchase.
Knowing the true cause—and likely repair costs—can help you negotiate confidently or avoid expensive surprises after moving in.
