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.
