The Solution 

How will Mr. Radon fix my home?

Fixing a home with a high radon level is usually referred to as “mitigating” the home.

Our simple guarantee is; “If we fail to reduce the Radon in your home below the Canadian ‘action level’ we will refund all our fees.”
 
If you have a radon test that is higher than the ‘action levels’ that Health Canada recommends for living accommodations, or you just want to lower your families exposure to radon gas we will proceed as follows:

Mr. Radon will analyze your home as to how it was built, type of foundation wall construction, basement floor finishes, size, age of building, and what level of Radon Gas your test showed. This information or as much of it as you know, is usually taken over the phone.

Mr.Radon will then book an appointment to complete a soil permeability or connectivity test. This will show us the permeability of  the gravel bed under the concrete. This will give us key information to determine the type of system that we recommend for your home. This service costs $200.00.

For an average urban home, with typical southern Ontario construction (about 95% of homes) we will recommend an active soil gas depressurization system.

This system averages $1950.00 completely installed including a retest. This retest will prove the system is now protecting your family from Radon Gas. We will be happy to provide you with a firm price to mitigate your home after we have completed the connectivity test.

Now here is the silver lining.....

Active soil depressurization has several other benefits that make your house a nicer place to live. The basement is drier, and most people comment within a few weeks that it smells different. The musty basement smell is gone. Active soil depressurization also removes methane gases and pesticides that may have been entering your home in the same fashion as Radon Gas.

After a mitigation system is installed the radon levels are reduced very quickly, as can be seen from this graph. 
Of course one cannot always assume that these kinds of reductions will occur and that they should be verified with short-term testing, conducted in a similar manner as the pre-mitigation testing.

Post-mitigation testing should start no sooner than 24-hours nor later than 30 days after the installation.  This should be a short-term test to quickly determine the efficiency of the system. 
Once the levels have been confirmed, a test should be conducted at least once every
two-years thereafter.
