Firstline Restoration is 5-star rated on Google and available 24/7/365 for emergency restoration, claim support, and reconstruction.
Radon Mitigation, Handled Start to Finish
Radon is a radioactive gas you cannot see, smell, or taste, and Health Canada names it the leading cause of lung cancer among Canadians who have never smoked. If a test has shown your level is high, every day you wait is another day of exposure, and the only real fix is a properly engineered mitigation system.
Firstline has spent 20 years solving exactly these problems across Caledon and the GTA. We are fully licensed and insured, WSIB covered, and 5-star rated on Google. We do not just install a fan and leave, we seal the entry points, vent the gas safely above your roofline, and re-test to prove the level dropped, all with one accountable team.

A High Radon Reading Is Not Something to Sit On
Radon comes from the natural breakdown of uranium in the soil and rock beneath your building. It pushes up through foundation cracks, sump pits, slab joints, and the gaps around pipes and services, then concentrates in the lowest occupied levels where your family, staff, or tenants spend their time.
Health Canada sets a guideline action level of 200 becquerels per cubic metre (Bq/m³). If your test came back at or above that line, the gas is not going to clear on its own, concentrations build over the heating season when the building is sealed tight. The sooner a mitigation system is in place, the sooner the exposure stops.
What Radon Mitigation Covers
Mitigation is the engineered work of permanently lowering the radon concentration inside an occupied building. A complete job is more than a single component, it is a system designed for your specific foundation and floor plan. It typically includes:
- A diagnostic assessment of your slab, sump, foundation, and how soil gas is entering
- Active sub-slab depressurization, a sealed pipe and continuously running fan that draws soil gas from beneath the slab
- Safe venting of that gas through a dedicated stack discharging above the roofline, away from windows and intakes
- Sealing of foundation cracks, slab joints, sump covers, and gaps around services to cut off entry points
- A system monitor or gauge so you can confirm the fan is working at a glance
- Post-mitigation re-testing to confirm the level has actually dropped below the guideline
Done right, all of this works together as one system. Skip a piece and the result is a fan that runs without delivering the reduction you paid for.
The Real Threat Is Cumulative, Quiet Exposure
Radon does its damage slowly. There is no smell, no irritation, no symptom in the moment, just a radioactive gas being breathed in day after day, year after year, until it shows up as lung cancer decades later.
- It is the number-one cause of lung cancer in Canadians who have never smoked, according to Health Canada.
- It is invisible and odourless, so no one in the building has any way to sense that the level is dangerous.
- Levels are highest in basements and ground floors, exactly where people sleep, work, and gather most.
You already did the hard part by testing. The reading is only useful if you act on it, call Firstline and we will get a system installed before another season passes.
Why One Fan Off the Shelf Is Not a System
The instinct after a high reading is to buy a fan, run a pipe, and hope the number comes down. The problem is that radon mitigation depends on what is happening under a slab you cannot see, soil permeability, the location of the sump, hidden footings that divide the sub-slab space into separate zones, and where the gas is actually pooling.
A system that is not designed around those conditions can move air without moving the radon, leaving the level barely changed while you assume the problem is solved. That false sense of safety is the worst outcome of all. Proper mitigation is sized, placed, and balanced for your building, then proven with a re-test, not guessed at.
How Firstline Handles Radon Mitigation
Why DIY and the Cheapest Quote Both Fail
Radon mitigation looks simple from the outside, a pipe, a fan, a hole in the slab. What it actually requires is reading an invisible gas under a concrete floor and proving you moved it. A homeowner kit or a bargain installer can leave you with a running fan, a real bill, and a level that never came down.
The cheap quote usually cuts the same corners: no proper diagnostic, no full sealing of entry points, a fan that is undersized, and critically, no post-mitigation re-test to confirm the result. Without that final test you have no proof the exposure stopped. We re-test every job because a radon system you cannot verify is not protection, it is a guess on your wall.
Homes and Businesses
In your home, the goal is simple, get the air your family breathes below the guideline and keep it there permanently. We design the system to run quietly, route the stack discreetly, seal your basement entry points, and leave you with documented before-and-after readings you can hand to a buyer or hold for peace of mind.
For businesses and managed properties, radon is a duty-of-care and liability issue across the spaces your staff and tenants occupy. We mitigate multi-unit, commercial, and managed buildings with minimal disruption, provide the documentation owners and property managers need on file, and coordinate the work around your operating hours so the building keeps running.
Where Insurance and Documentation Fit In
When radon mitigation is tied to a larger covered loss, a flooded basement, a foundation repair, a rebuild, carriers pay for what is documented, not for what was actually damaged. We manage the claim from first notice to final payment and document the work thoroughly so nothing legitimate gets left off the file.
