Keeping your loft dry

General, Loft conversion

Loft conversions remain a very popular home improvement, providing many houses with useful additional living space. Not until after the conversion work has been completed do the occupants really understand and appreciate how beneficial a loft space can be. Likewise with any building work, it is crucial to take care of your newly-converted space and understand the potential problems that could occur.


One of the problems you may encounter is excess condensation, but do not worry as this is not linked to any building fault.  Day-to-day activities such as showering, washing and cooking can all produce large amounts of warm air therefore producing water vapour. If this warm air does not have anywhere to escape, it circulates and rises until it can find a cold surface onto which it forms condensation. The amount of insulation laid above the loft ceiling can determine how effectively energy is restored and subsequently the overall warmth of the house. If there is a lack of insulation the loft ceiling and roof will remain cold, making it an ideal area for the formation of condensation. However, condensation is a minor issue and is often temporary, so not to panic.

Tips to reduce condensation:

  • Reduce the amount of moisture you produce
  • Improve ventilation in your house
  • Reduce the number of cold surfaces by adding insulation
  • Maintain an adequate temperature in the house

Condensation can sometimes be a predecessor for larger issues, namely mould and damp, which are common but largely treatable problems. It is important to identify the problem earlier rather than later to avoid possible damage to your loft conversion.

Mould and damp are a result of a combination of wet and cold weather and commonly appear in poorly ventilated areas. The lack of ventilation means that the excess moisture can become trapped and cause dampening.  Identifying any possible trouble areas in your loft conversion can help you prepare and prevent getting mould or damp.  Taking preventative action against excess moisture can significantly reduce your chances of getting mould or damp.  For those who already have damp/mould or potential symptoms of it, there are various builders and specialists that can offer valuable and tailored advice.

It’s easy to forget about this sort of thing but by thinking ahead you can ensure you get the most out of your converted (and hopefully dry) loft space.
