About us

The stone that guards your home

Radon rises silently from the rock beneath your home — invisible, odourless, and one of the leading causes of lung cancer. We built Onyx Radon to stand between that threat and the people you love.

Our name

Why "Onyx"

Onyx has stood for protection for centuries — a stone, drawn from the same earth, that guards the home and those within it. It felt right: radon comes from the ground, so does onyx, and so does our solution. We bring that protection to your foundation — rock-solid defense against the threat from below, so the air your family breathes stays clean.

Our standard

Certified, diagnostics-driven, honest

Our promise

To treat your home like our own, to measure honestly, and to fix it properly — so radon becomes one thing you never have to worry about again.
