The mould issue is almost universal in London property – we live in an often damp climate and struggle to remain dry, and this damp can lead to mould. It’s a particular issue in older properties with new double glazing as there is less of a through-flow of air. The advantage is added warmth in winter, but the disadvantage that you need to be rigorous in damp management.

For this reason, we recommend opening windows on both sides of the house for a sufficient time in the morning, making sure doors in between are held open. You need to factor this into your routine – if it’s cold you can open windows, put a coat on, do 30 mins chores, close up and go.

It really is down to how long you let the air come through. If you object to the sufficient degree of ventilation – eg., if it’s particularly cold – you can do a daily wipe where the condensation is collecting, before the mould gets established.

Sometimes mould collects behind furniture, and it can also help to move items away from the wall, but the emphasis is “Whole House Ventilation.”

It’s recommended to keep specialist anti-mould cleaners in your home for regular cleaning, but time and again experience shows that increasing ventilation is the answer.

Key concepts – “whole-house” and “through-flow of air”-

In short:

  • Wipe down affected areas with specialist mould spray. This can be purchased from most supermarkets or hardware shops.
  • Avoid using products like bleach or washing up liquid as they do not kill the mould effectively.
  • Wipe down surfaces where moisture settles.
  • Ventilate your home by opening windows and vents each day.
  • It is important not to disturb the mould by vacuuming because this can increase risk of breathing problems
