Most homeowners in Nova Scotia pay between $2,200 and $3,800 for a complete radon mitigation system. Actual cost depends on your foundation type, home size, and the complexity of the installation. Request quotes from multiple professionals to compare.

Dartmouth follows Health Canada's national guideline of 200 Bq/m³. If your home tests above this level, Health Canada recommends taking action to reduce radon within two years for levels between 200 and 600 Bq/m³, and within one year if above 600 Bq/m³.

Yes. Health Canada recommends testing every home in Canada, regardless of age, construction type, or location. Radon levels vary from house to house and even neighbouring homes can have very different readings. A long-term test of at least 91 days during the heating season is the most reliable method.

The most common system is active sub-slab depressurization (ASD). A certified professional installs a pipe through your foundation slab connected to a fan that draws radon from beneath the home and vents it safely above the roofline. Installation typically takes one day.
