Professional radon screening that fits inside a property sale. We schedule around your transaction, place the monitor correctly and deliver a clear, documented report that buyers and sellers can use to make more informed decisions before closing.
Conducted by a C-NRPP certified radon measurement professional, following CARST's Radon Screening Assessment protocol (opens in a new tab).

Your report uses CARST's three result categories to show how likely it is that the home's long-term radon average is above Health Canada's guideline. Every result, including a low one, gives you useful, documented information for the transaction.
Green result
A Green result is useful, documented information for buyers and sellers. Under CARST's protocol, no additional testing is generally needed before purchase. It isn't a guarantee that the home's long-term average is below Health Canada's guideline, so a long-term test after possession is still recommended.
Yellow result
A Yellow result means there is a higher likelihood that the home's long-term average could be above Health Canada's guideline. It's worth discussing as part of the deal, for example by planning long-term testing after possession and allowing for possible radon reduction.
Red result
A Red result means there is a strong likelihood that the home's long-term average is above Health Canada's guideline. It can inform discussions about possible mitigation or other arrangements in the transaction. A long-term test confirms the home's actual average.
Categories as defined in CARST's Radon Screening Assessment (opens in a new tab) guidance.
A screening assessment gives a time-specific indication of the likelihood of elevated radon during a transaction. It isn't a substitute for long-term testing, so buyers should arrange a long-term test after taking possession, ideally during the heating season.
We start a 48-hour preliminary check with a professional radon monitor and place a long-term laboratory detector at the same visit. You get an early snapshot within days, while the long-term test builds the clearer picture of your home's average radon level.
