Calculate dew point and condensation risk in your home. Understand when and where moisture will form, leading to damp and mould problems.
This tool helps understand condensation, but persistent damp needs professional diagnosis. Our surveyors identify the true cause of your moisture problems.
Learn why condensation forms and how it leads to damp and mould problems.
Dew point is the temperature at which air becomes saturated with moisture. When air cools to this point, water vapour condenses into liquid water.
When warm, humid air touches a cold surface (like a window or wall), the air cools locally. If it cools below dew point, moisture condenses on that surface.
Persistent condensation creates perfect conditions for mould growth. Mould spores are always present - they only need moisture and organic material to grow.
While this calculator helps understand condensation, persistent damp problems need professional diagnosis. Condensation can often be confused with rising damp or penetrating damp - each requires different treatments.
