Radon Mitigation and Testing
After you receive the results for a 91+ day test, making the decision to mitigate can be easily decided. Radon Mitigation's can come in all shapes and sizes.
New homes after 2015 should have a rough-in already in place. This makes mitigating the home, relatively straight forward.
Older homes can be a challenge, but can still be done. Depending on the situation of the house, whether there were additions or alterations, load bearing walls in the basement, etc., these can all affect how the mitigation will proceed. If you are about to renovate or are in the middle of one, deeply consider implementing a system before the project is finished as this will make integration of the system seamless.
Radon Measurement
We also provide measurement services. Using the Alpha Track products from RADONOVA, you can rest assured knowing that your test is being handled by one of the many approved devices by the C-NRPP. It is HIGHLY recommended that you make the decision to mitigate based on long-term test results, 91+ days or longer.
Canada's acceptable radon level is 200 Bq/m3, any higher and it is recommended to mitigate. Just for comparison, the World Health Organization sets the standard at 100 Bq/m3.

New Home Mitigation
Some times, the builder could have missed putting the pipe in, or the house could have been permitted before new codes took effect and did not require a roughed-in system. All that is required for a Roughed-In System for a new build is a effective air barrier that meets the guidelines and a pipe that extends 300mm or One Foot above the slab, this pipe should connect to approximately the center of the space under the concrete. After communication testing, we will be able to determine the next course of action.
Older Home Mitigations
Homes before ~2015 did not require roughed-in systems for Radon. Depending on the house, double extraction points may be needed. Typically if there is a load bearing wall in the basement, it will be difficult to get air movement between the suction hole and the Air Test holes. Quite a few Radon Mitigators do not do what we call "communication" testing. Communication testing means drilling small holes, usually in the corners of the basement slab, and testing for an air flow between those holes and the central extraction point. If the air movement proves to be adequate, Radon concentration levels have no where to go but down.
Real Estate Measurements
There are multiple options for a Short-Term test. There are one-time use devices that can be sent off for analysis, similar to the long-term devices. Or, there are Continuous Radon Monitors that can release a report after a few days.
Commercial Mitigations
Commercial buildings are more intricate to perform and may require additional experts to be consulted for a successful mitigation.
