Other checks for Dublin

Designated parts of the Fingal County Council area are in the Defective Concrete Blocks grant scheme (mica and pyrite in blocks). Only those parts are covered, not the whole county, so ask the council whether a particular address is inside the designated area.

Dublin is in the pyrite belt. Houses built roughly 1997 to 2013 with hardcore from the affected quarries may have heave in floors; the Pyrite Resolution Board ran the remediation scheme. The report flags the build years and the scheme for the exact house.

Questions people ask

Is Dublin a high radon county?
17 of the 279 town centres we sampled in Dublin are in an EPA High Radon Area (1 in 5 homes or more predicted above 200 Bq/m³). Nationally it is 36% of towns. High towns include Sandyford, Killiney, Leopardstown, Stepaside, Foxrock, Sandyford Dublin 18.
What does a High Radon Area mean for a buyer?
Houses built after 1998 in a High Radon Area must have a radon barrier. Older houses usually have none, and one in five will test above the reference level. It costs €50 to €60 to test after you move in and €1,500 to €3,000 to fix. Ask the seller for any test result.
Why does radon vary so much within a county?
Radon comes from uranium in the underlying rock. Granite and some limestones give high readings; the map follows the geology, so it changes over a few kilometres. The exact Eircode grid square is what matters.
