Radon in New Homes: What Alberta Builders and Homeowners Need to Know

It’s a common misconception that new construction homes are somehow naturally protected from Radon, but that isn’t the case at all. To address this, given Alberta's interest in energy-efficient buildings with Radon in New Homes, it is essential for builders to incorporate Radon prevention into the design and initial build phases to ensure Alberta homes remain safe from contaminated indoor air.

Understanding of Radon in New Homes

Ironically, the current trend of constructing tightly sealed, energy-efficient homes may actually exacerbate Radon buildup. With less airflow to dilute indoor gases, it is crucial to know about Radon in New Homes.

Alberta's Radon Risk of Radon in New Homes

Health Canada and C-NRPP professionals have shown that radon levels in Alberta exceed the recommended safe threshold. That data underscores that new construction alone does not eliminate risk; proactive measures are still required during and after construction to mitigate Radon in New Homes.

Thinking About Post-construction Prevention of Radon in New Homes

Construction techniques also influence how a home resists Radon accumulation in New Homes. Primary preventive measures include subslab gravel layers to vent soil gases, sealing cracks in building foundations, and installing a soil gas barrier system.

Builders' Radon Mitigation in Alberta: Radon in New Homes

According to the Alberta Building Code, all new homes with a foundation in contact with soil must have rough-in Radon mitigation systems in place. By collaborating with certified professionals in the Radon mitigation community, best practices can ensure that these goals are met. 

Testing Radon in New Homes: When and How to Do It

Tests lasting 91 days or more are considered the most accurate. Homeowners can test using do-it-yourself kits or contract with certified Radon measurement professionals. Should higher levels be found, new construction installation is a breeze with the pre-installed rough-in system, enabling you to get your home up to Health Canada’s recommended guidelines.

What to do About Radon in New Homes

The most common and efficient Radon mitigation method for new homes is active soil depressurization, which pulls the gas from beneath a house before it can seep into the living quarters. 

Roles and Responsibilities (Builders vs. Homeowners)

Builders can also help protect homeowners by installing Radon-resistant materials and systems in new homes during construction, in accordance with provincial building codes. Regular testing every several years or whenever there is significant remodeling can help ensure that Radon levels stay low and protect the home’s occupants for years to come.

Regulations and Assistance with Radon Safety in Alberta for Radon in New Homes

Federal and provincial programs also encourage Radon education and testing, including through initiatives such as Take Action on Radon. These resources help keep homeowners and builders informed about available mitigation options, test kits, and certified professionals throughout the province.

Conclusion: Safer, Healthier Homes All Over Alberta

As Radon knowledge continues to grow, the addition of Radon control systems in every new residential construction will soon become a standard practice. 

FAQ: Radon in New Homes

Can brand-new homes still have high Radon levels?

Absolutely. New homes can have a high Radon level, just like any other home, especially in Radon-endemic areas of Alberta, due to natural soil gas intrusion.

What is a Radon rough-in, and how does it function?A Radon rough-in is a network of pipes beneath the foundation that can be used to vent Radon outside, but must be upgraded to a fan-activated system.
