// CLIPS FROM Radon Repair Inc.
“so that's the problem is when we're in a building or a home we tighten it all up”
“there's warnings that I have in that you can cause other problems by trying to fix your radon problem”
“if you could picture our house like a chimney right it's basically a chimney”
“so in Canada we are mandated when we fix a home to take air pressure differentials”
“so I went home started Googling and get on the machine and realized that New Brunswick has the highest levels”
“we're focused on energy efficiency right in our homes and buildings and that's a good thing”
“our prices on our radon mitigations are probably five times higher than theirs in Canada”
“the typical test what Health Canada recommends is a long-term test 90 days or more”
“so right now a lot of it tends to be government bodies right so in New Brunswick every school has been tested”
// LESSONS FROM Radon Repair Inc.
Tightening a building's thermal envelope for energy efficiency simultaneously increases radon accumulation — the two goals are in direct tension and contractors need to account for both.
The real carcinogenic hazard in 'radon' is not radon gas itself but its decay products — polonium and bismuth — which stick to lung tissue; understanding the mechanism helps contractors communicate risk credibly to clients.
Canada's residential radon action level dropped from 800 to 200 Bq/m³ roughly a decade ago, effectively quadrupling the number of non-compliant homes; the commercial OSHA standard is still at 800 and is expected to follow — creating a large retrofit wave for contractors who are ready.
New Brunswick adopted the 2010 National Building Code radon rough-in requirements in 2015; contractors who understand why — stack-effect sub-slab pressure — install the rough-ins correctly rather than as a box-tick obligation.
Over-sizing a sub-slab radon fan can depressurise the house enough to back-draft combustion appliances and blow out pilot lights; Canadian practice mandates measuring and optimising differential pressures before specifying fan size — a discipline the US radon industry is only beginning to adopt.
Real-estate transactions create a structural demand for 4-day radon screening assessments even though Health Canada recommends 90-day tests — operators who offer both services (screening + long-term follow-up) capture the transaction trigger and the remediation lead.
