Frequently Asked Questions

Damp can be caused by several factors, including condensation, rising damp, penetrating damp, poor ventilation, plumbing leaks, or structural defects. A professional damp survey is the best way to identify the true cause.

Common signs of rising damp include tide marks on lower walls, peeling paint or wallpaper, damaged plaster, salt deposits, and damp skirting boards. However, condensation and penetrating damp are often mistaken for rising damp, which is why proper diagnosis is important.

Condensation is caused by excess moisture in the air settling on cold surfaces, often leading to mould growth. Rising damp comes from moisture travelling upward through walls from ground level. They are different problems and require different solutions.

Not always. Some damp problems are caused by ventilation issues or water ingress rather than a failed damp proof course. A damp survey can determine whether a DPC is actually required.

Yes, prolonged exposure to black mould can affect indoor air quality and may aggravate respiratory conditions, particularly in children, older people, and those with asthma.

A Positive Input Ventilation (PIV) system introduces fresh, filtered air into the home to reduce humidity, improve airflow, and help control condensation and mould.

Yes. Constant running silent extractor fans help remove excess moisture from bathrooms, kitchens, and other humid areas, reducing condensation and supporting damp prevention.

Standard mortgage valuations and many homebuyer surveys are not specialist damp inspections. If damp is suspected, a dedicated pre-purchase damp survey is strongly recommended.

Our pre-purchase damp survey is £100 + VAT, and if you proceed with the property, that cost is deducted from any damp remedial work we carry out.

Costs vary depending on the cause of the problem, extent of the issue, and the solution required. We provide clear recommendations following a professional damp survey.
