 This week, we sit down with Rebecca Coates, Head of Radon Projects at PropertEco. Who has spent over 16 years managing radon testing and mitigation programs across the UK, to explore a question that fundamentally challenges how we think about indoor air quality and home safety: Our complete failure to recognise that for the price of a family meal out, any homeowner can test their property, that remediation is not tearing up floors or spending tens of thousands, but drilling one hole from outside and installing a fan in an afternoon, and that until we treat radon mitigation like servicing a boiler, something routine and well understood, over 1,100 people a year in the UK alone will continue to die from lung cancer caused by a gas they never knew was there? Key Topics Discussed: What Radon Remediation Actually Looks Like: Radon remediation is not about cleaning contaminated materials or tearing up your home. Once the gas is gone, the problem is solved. The most common solution is a radon sump system installed from outside the building. A small hole is core drilled beneath the foundations, a void is excavated to create a point of low pressure, and pipework with an inline fan draws radon out from beneath the building and discharges it safely above roof level. The work is completed in a day. It costs around three to three and a half thousand pounds for a standard residential property. No one needs to leave their home. There is no dust inside. It is not disruptive. And in 95 percent of cases, it works first time. The Suspended Floor Challenge: Suspended timber floors are more complicated than solid floors. You have a ready made void running under the whole footprint of the building. Sometimes extracting from that void works beautifully. Sometimes it makes levels worse by drawing more radon up through the floorboards. There is no one size fits all solution. It can require trial and error. Sometimes the answer is to ignore the floor void completely and drill deeper beneath the building to create a sump at a lower level. Suspended floors bring moisture risk, thermal performance, air movement and radon together in ways that require multidisciplinary expertise. Many radon specialists come from property preservation backgrounds precisely because of this complexity. Ventilation as a First Line of Defence: Where radon levels are moderate, improving ventilation can be enough. Radon is a gas. Dilution works. Somewhere between 50 and 75 percent of homes do not have adequate ventilation. Fixing that can solve radon problems and bring co benefits for damp, mould and condensation. Positive input ventilation can work by gently increasing air pressure in the building to inhibit radon ingress and by diluting what is already there with fresh filtered air from outside. For low to moderate radon levels, this can be a very effective first step before considering a sump system. The Awareness Gap and the Path Forward: The biggest problem is that people do not know what they do not know. Carbon monoxide awareness has grown dramatically over the last two decades. Most homes now have a carbon monoxide alarm as standard. Considerably fewer people die each year from carbon monoxide poisoning than radon induced lung cancer. Yet radon remains invisible in public consciousness. The UK has one of the best radon maps in the world. Testing costs about fifty pounds. Remediation is straightforward. But unless the message reaches the man on the street, nothing changes. Social housing and schools are starting to take this seriously. The missing piece is the homeowning population. Radon testing should be as routine as an MOT on your car. You spend far more time in your house than your car. It is a one off cost to know whether the environment where your family spends 90 percent of their lives is safe.
