How can damp be detected if there are no visible signs?

Damp can often be detected before visible signs appear by looking for:

• Musty odours – A persistent damp smell is often an early warning sign.
• Cold or clammy walls – Damp areas feel colder due to moisture retention.
• Peeling wallpaper or paint – Moisture weakens adhesives, causing finishes to bubble or peel.
• Condensation issues – Excess moisture on windows or mirrors can indicate high humidity.
• Professional damp meters – These can measure moisture levels in walls and floors.
