It is common belief that the only way to clear dampness and mould is to turn on your heating for long hours, or to leave your windows wide open until the house is freezing. These methods can be sometimes uncomfortable, and your concern is the energy bill is going to skyrocket.

The reality of building science is much simpler: mould thrives on trapped indoor moisture. By making small, budget-friendly changes to how you manage that moisture, you can drastically improve your home’s indoor air quality without relying on your thermostat.

Many residents and landlords struggle with this simple question: when should you open your windows, and will it cost a lot to heat up again? It sounds funny, but it’s a real dilemma.

During winter, people often hesitate to open windows because they don’t want to lose heat and waste energy. 

However, keeping windows closed all the time can create costly problems like poor indoor air quality (high CO2), condensation, and even mould.

The government announced a landmark move: Awaab’s Law will require landlords to fix problematic homes, starting with damp and mould. This affects social landlords immediately, and potentially later for private landlords too. 

In 2020, Awaab Ishak died in social housing in Rochdale, due to a severe respiratory condition.
