What moves the price
- Size of the property — a larger home may need radon detectors in more rooms and, for mitigation, a bigger system.
- Complexity of the mitigation required — a high radon level may need a sump with a fan rather than passive ventilation.
- Existing infrastructure — solid floors, cavities and existing pipework change how a radon mitigation system is fitted.
- Testing alone or full mitigation — a radon test costs much less than designing and installing a mitigation system.
Services for the maintenance and repair of the dwelling prices in Ireland are up 23% over five years (CSO Consumer Price Index, Services for the maintenance and repair of the dwelling, to 2025 December). Five years ago a typical radon testing & mitigation would have cost about €320 — an estimate from today's guide price and that index, not a recorded price. Source: CSO CPM18, CPM12 →

How to pay less
- Starting with a radon test costs far less than mitigation, and the result shows whether any further work is needed.
- Where radon levels are only slightly raised, better ventilation may cost less than a full sump system; you can ask which suits.
- Having radon mitigation fitted during other floor or extension work can cost less than lifting floors for it later.
- A postal radon test, where you place and return the detectors yourself, usually costs less than a site visit.
Before you book
- Tell the provider whether you need a radon test only or mitigation too, and share any earlier test results.
- It helps to say how the ground floor is built, such as solid concrete or suspended timber, before the radon visit.
- You can ask how long the radon detectors stay in place and which rooms they go in.
- Agree before the day where any radon sump pipe and fan will be placed outside the house.
- You can ask whether the provider is trained and registered for radon testing and mitigation work, and whether any local rules apply.

If high levels are detected, a mitigation plan will be developed to reduce radon exposure effectively. Radon testing and mitigation is a crucial service aimed at identifying and reducing radon gas levels in residential and commercial properties.
While DIY kits are available, professional testing is recommended for accurate results and proper mitigation. The process typically involves measuring radon concentrations in the air and, if necessary, implementing solutions to lower exposure to this harmful gas.
It is advisable to test for radon every two years or after any major renovations. Be aware that mitigation systems require regular maintenance for continued effectiveness.
