Questions about condensation and mould ventilation fixes in County Armagh

Is the survey free in County Armagh?

Visits here are by arrangement. Because of the ferry or long travel involved, we quote travel separately and in writing before you commit, and we can often combine visits to keep the cost down.

Can you tell if it is rising damp?

We can tell you when the pattern does not look like condensation, such as a tide mark low on a wall or damp that appears after rain, and point you to the right specialist.

What is the main cause of condensation in a house?

The main cause is moisture from everyday living, such as showers, cooking and drying clothes, that is not being extracted, combined with cold surfaces where it condenses. Poor or failed extract fans are a very common cause.

Which rules apply to ventilation in County Armagh?
