Radon rises silently from the rock under your home — odourless, invisible, and a leading cause of lung cancer. Onyx Radon brings certified testing and mitigation to your foundation.
Alberta sits on some of the highest radon levels in Canada. Radon gas seeps up from the ground into homes, where it concentrates in the air your family breathes every day. The only way to know your level is to test — and the only way to fix it is proper mitigation.
Accurate short- and long-term measurement of radon levels in your home, to the C-NRPP standard. Know exactly where you stand.
Professionally designed sub-slab depressurization systems that pull radon out before it reaches your living space — built into your foundation.
We re-test after mitigation and provide documented proof that your home is safe — ideal for real-estate transactions.
Onyx has stood for protection for centuries — a stone, drawn from the same earth, that guards the home. We bring that same solidity to your radon defense.
Radon comes from below. So does our solution. A properly engineered mitigation system intercepts the gas at the foundation and vents it safely away — before it ever reaches the air you breathe.
Fast, certified radon testing and mitigation for real-estate transactions — documented, reliable, and on your timeline. Build us into your buying and selling process.
