Radon gas is an insidious carcinogen which may appear through basement floors or perforations (cracks, sewer, water and gas pipes). It is also variable and dependent on the underlying geology. Several years ago, our board tested our three multi-storey towers; they were radon-free (I was told!).
Kenida, I suggest you approach the board to have all the buildings in your complex tested and spread the (reduced?) per-unit cost across all units. If you have forced-air heating systems, all units could be affected. As we try to make our homes more airtight for energy efficiency, we increase the risk (if testing finds there is one) from radon.
CHECK YOUR BYLAWS – who pays for testing? It may be something which the corporation could contract and get paid back by unit owners if it isn’t covered as a safety expense covered by the corporation.
If some remediation is required – again – who pays? Do your bylaws say who is responsible for such expenses? If all the basements were found to be affected, does the corporation have the power to contract for a significant remediation job and charge it back to all the owners?
Please let us know what you decide – this is a question that all owners of at-ground units should be concerned about.
