Radon Mitigation Kelowna

Radon is an invisible gas that can threaten the health of anyone spending time indoors.

In Canada, radon gas is now the leading cause of lung cancer next to smoking. An estimated 30% of homes in the BC interior have dangerous radon concentration levels.

Our solution? A cutting-edge spray foam insulation that’s engineered to prevent radon from entering your home. With our professional installation service, we can create a protective barrier between your loved ones and help you mitigate the health risks of radon exposure.


What is Radon Gas?

Radon is a naturally occurring radioactive gas that’s colorless, odorless, and tasteless.

Radon forms during the decay of uranium in rocks, soil, and water. Once released, radon can attach to dust particles and enter the air we breathe.

According to the radon map published by the BC Centre for Disease Control, an estimated 30% of homes in the BC interior are above the safe radon level of 200 Bq/m³.

Dangers of High Radon Levels

Radon is classified as a carcinogen by the International Agency for Research on Cancer (IARC). The longer you are exposed to high levels of radon, the greater your chances of developing cancer.

Health Canada estimates that about 16% of lung cancer deaths are related to radon exposure at home – resulting in over 3,300 lung cancer deaths every year.

Interior Health stresses the importance of radon awareness, recommending that people living in the Okanagan Valley test their homes using radon test kits available at libraries, hardware stores, through the BC Lung Foundation, or through a radon professional.

To keep radon levels as low as possible, it’s important to have high quality insulation and a radon mitigation system installed by a C-NRPP Certified radon professional.

Spray Foam: The Best Insulation for Radon Mitigation

Closed cell spray foam insulation is considered the best insulation for radon gas mitigation due to its air & moisture sealing properties, high R-value, and durability.

Air Sealing Properties

Closed-cell spray foam creates a uniform barrier against air infiltration, tightly sealing the tiniest gaps, cracks, and openings in walls, floors, and foundations.

Dense closed-cell foam restricts gas diffusion, creating an impermeable barrier against microscopic radon gas atoms.

Strong Vapor Barrier

Radon tends to move more easily through damp soil, making moisture control essential for any home radon mitigation effort. Closed-cell spray foam acts as a vapor barrier, preventing moisture from seeping through walls and floors.

High R-Value

Closed-cell foam has an impressive R-value (thermal resistance), keeping your home warm in winter and cool in summer.

The high R-value also helps maintain consistent indoor temperatures, reducing the stack effect that draws radon into your house.


Once cured, closed-cell foam is a dense and rigid barrier that doesn’t sag or settle over time.

Unlike other insulation materials, it won’t degrade due to moisture or pests, ensuring long-term protection against radon gas.

How Radon Enters Your Home

Radon gas moves through the ground and enters homes through openings where the house contacts the ground:

  • Cracks in foundation walls and floor slabs
  • Basement window casements and seals
  • Crawl space access points and walls
  • Gaps around utility penetrations like electrical, plumbing service pipes, or HVAC conduits
  • Ducts, floor drains, sumps or wall cavities
  • Construction joints and concrete/masonry floor-to-wall joints
  • Hollow block walls or bricks with mortar joints
  • Gravel or dirt floors in crawl spaces

Why Radon Levels Are Higher in Winter

During winter, indoor radon levels are usually higher compared to other seasons, making it a time of increased radon exposure risk in Canadian homes.

When the ground freezes in winter, the soil becomes less permeable, forcing radon atoms upwards.

With our homes heated to be warmer than the outdoors, the higher air pressure inside causes a pressure differential that suctions radon gas from the soil into your home.

Due to snow buildup around the foundation and keeping doors & windows closed, radon accumulates indoors due to reduced ventilation and airflow.

The stack effect further contributes to radon exposure risk in winter. When rising warm air escapes through the upper levels of the house (such as the attic or roof), it creates a negative pressure zone at the base of the house. Radon gas, being denser than air, moves upward from the soil and enters the home through openings in the foundation.

Just like water flowing downhill, radon takes the easiest path available into your home. Quality insulation is essential to sealing these entry points effectively, safeguarding your health from this invisible threat.

While insulation alone is not a direct method for radon mitigation, it plays a crucial role in reducing radon levels and increasing the effectiveness of your radon mitigation system.
