Basement Renovation Ottawa
Basement Radon Mitigation Ottawa: Make Your Basement Safe to Live and Sleep In
Ottawa sits in a high-radon region. We test and mitigate radon in basements, sub-slab depressurization integrated with your finish, suite, or bedroom. Book a radon assessment.
Typical Ottawa cost
Tested first, then quoted
Health Canada describes mitigation as comparable to other common home repairs, usually installed in under a day. We only recommend a system when your reading is above the guideline.
Permits
Pulled on every job
We pull every required City of Ottawa permit and manage the inspections, documented, insurable work.
Built to code
Confirmed before we build
Testing and mitigation follow Health Canada’s guidance (the 200 Bq/m³ guideline) and are carried out with C-NRPP-certified professionals, with a post-mitigation re-test to prove the result.
Why Radon Matters in Ottawa Basements
Radon is a natural radioactive gas that seeps up from the ground, and Health Canada notes it can be found in almost any home in Canada, the Ottawa region included. It collects in basements, which matters most exactly when you’re about to spend more time down there: a new bedroom, a finished family room, or a suite where someone sleeps every night.
This isn’t fear-mongering, it’s the reason to test. Health Canada’s guideline is 200 Bq/m³; below that you’re fine, and above it the gas should be reduced by a certified professional. The only way to know your level is to measure it, which is why radon is worth checking before you finish the space, not after.
Testing & Mitigation
Radon is measured, not guessed, so the process starts and ends with a number.
-
Long-term test
Health Canada recommends measuring for at least three months for an accurate reading, the number you act on.
-
Sub-slab depressurization
If you’re above the guideline, a quiet vent system draws radon from under the slab and releases it safely above the roofline.
-
Sealing
We seal entry points so the system works as efficiently as possible.
-
Post-mitigation re-test
We re-test to prove the level actually came down below 200 Bq/m³, documented results, not just an installed fan.
Mitigation Built Into Your Renovation
The smart time to deal with radon is during the finish or suite build, while the slab and walls are still open, not bolted on awkwardly afterward. We sequence the mitigation into the renovation so it’s tidy and hidden, and we work with C-NRPP-certified radon professionals so the testing and system meet the national standard. A mitigation system can usually be installed in under a day and reduces radon by more than 80% in most homes.
