Believe it or not, there are up to 900 chemicals in indoor air. Not only this, but according to the Environmental Protection Agency, indoor air is found to be up to 70 times more polluted than outdoor air.

Bryony Perry, Specialist Ventilation Expert at the UK's leading ventilation manufacturer, EnviroVent, gives her advice on preventing mould and condensation issues in landlords’ properties.

There are several types of condensation: surface condensation, cold-bridge condensation, warm-front condensation, interstitial condensation, reverse condensation, radiation condensation.

As any architect, planner or developer knows, the process of building and maintaining any property is hedged around at every corner with various regulations to ensure the safety of occupants. Ventilation is no exception to this rule.

All homes need to have adequate ventilation - it can help to prevent damp and mould caused by condensation, and can reduce the chances of contracting health issues caused or exacerbated by poor indoor air quality.

The majority of the world’s population breathes air that is harmful, according to a major new study. The State of Global Air report, released in April 2018 by the Health Effects Institute, estimates that 95% of people around the globe live in areas where concentrations of fine particulate matter, such as dust or soot particles in the air, exceed the World Health Organization’s Air Quality Guideline of 10 micrograms per cubic metre of air (µg/m3).

Many tenants tend to ignore the early signs of condensation and never mention it to their landlord until the problem has exacerbated, causing mould to spread across your walls, windows and ceilings. Despite the problem lingering for months beforehand the tenant then expects you to solve the problem in a timely manner and completely redecorate the damage that has been done.

Most of us first encounter mould when we are children whilst at school learning all about Alexander Fleming and his famous discovery of penicillin. Today many of us may also be experiencing mould in our own homes, around our windows, walls and even doors.
