Landlords Warned About Hidden Gas Risks Inside Rental Properties

Understanding the Hidden Gas Hazard

Health authorities and industry monitors have issued important warnings reminding a property owner or landlord to look out for invisible gas risks inside rental properties. Specifically, experts highlight that radon accumulation remains a major health concern for occupants across residential spaces.

Radon is described as an invisible, odourless, and tasteless radioactive gas formed by the natural breakdown of uranium in soil and rock. While it safely disperses outdoors into the atmosphere, it can seep through foundation cracks, gaps around pipes, and floor drains to build up inside enclosed lower building levels.

Testing Rental Properties for Safety

Experts emphasize that neither the age nor the market price of a building serves as a reliable indicator of its safety. Elevated concentrations can occur in newly built expensive houses just as easily as in older structures. Because exposure to the gas over prolonged periods is a leading cause of lung cancer among non-smokers, routine assessment is vital.

Property managers and any responsible landlord should understand that proper evaluation requires a long-term test spanning at least three months, ideally conducted during the fall or winter seasons when windows remain shut and heating systems operate normally. Residents can utilize do-it-yourself kits placed on the lowest regularly occupied level or employ certified measurement professionals.

Mitigation and Next Steps

When monitoring reveals elevated concentrations, corrective measures must be implemented promptly because no level is entirely risk-free. Certified mitigation professionals typically resolve high readings by installing specialized extraction systems designed to draw the gas from beneath foundations and safely vent it outside.

Following any mitigation work, re-testing is necessary to confirm that the installed system functions correctly. Stakeholders navigating property transactions or major renovations are also advised to check historical testing records or incorporate assessments directly into upcoming project timelines.
