Radon Testing and Mitigation in Ottawa

Radon is a radioactive gas that comes up out of the ground and collects in basements. You cannot smell it or see it, which is why the only way to know is to measure. Health Canada sets the action level at 200 becquerels per cubic metre. We test first, and only recommend a system if the reading calls for one.

What We Do

Gas Line Installation

New lines run to a barbecue, a garage heater, a range, a dryer or a pool heater. Sized for the appliance and for everything already on the system, not just the new load.

Appliance Gas Hookup

Connecting a new range, dryer, fireplace or heater to an existing line, with the shut-off and connector the appliance actually requires.

Gas Leak Testing

If you can smell gas, leave the building and call the utility emergency line first. For a suspected slow leak or a peace-of-mind check, we pressure-test the system.

Permits Handled

Gas work requires permits and inspection. We pull them as part of the job rather than leaving you to arrange it afterwards.

Capacity Checked First

Adding an appliance to an already-loaded line starves everything on it. We calculate before we connect.

Documented and Tested

Every line is pressure-tested and the result recorded. That record matters when you sell the house.

Why Ottawa Homes Test

Radon levels depend on the ground under the house and how tightly the house is sealed, not on the age or price of the building. Two identical homes on the same street can read very differently. Winter is the honest time to measure, because the house is closed up and the readings reflect the worst case rather than the best.

What a Mitigation System Is

A fan draws air from beneath the concrete slab and vents it above the roofline, so the gas never enters the living space. The pipe runs where it can be hidden. A monitor on the pipe shows at a glance that the fan is still pulling. Most installations are a single day.

Common Questions

How long does a radon test take?

A long-term test runs at least three months, and that is the measurement Health Canada asks for. A short-term test gives you an early indication in a few days, but it is a screen, not a verdict.

What reading means I need a system?

Health Canada’s guideline is 200 Bq/m³. Above that, remediation is recommended. Between 100 and 200 it is a judgement call and worth discussing.

Will the fan be noisy?

It runs continuously but it is a small, low-wattage fan, usually mounted outside or in an attic. Inside the house you are unlikely to notice it.

Do you retest after installing?

Yes. A system that has not been verified is only a guess. We measure again once it has been running so you have a before and after.

Book a Radon Test

Tell us roughly when the house was built and whether the basement is finished. That is usually enough for us to say what the test will involve.
