What’s Hiding in the Air Beneath Your Feet?
Radon is a colorless, odorless gas that can enter your home through cracks in the foundation – and long-term exposure is the number one cause of lung cancer for non-smokers in the U.S.
Unfortunately, many Maine waterproofing companies unintentionally make radon problems worse. The same holes created to remove water and moisture from your home can actually make it easier for radon to enter.
At Evergreen, we take a different approach. Our basement waterproofing services don’t just keep water out – they keep your air safe as well.
When you work with Evergreen, you get:
- A free basement consult with a free radon test kit (*as long as you don’t already have a mitigation system in place and haven’t recently tested for radon)
- Solutions that protect both your basement and your indoor air quality
- A partnership with trusted local radon experts at Air & Water Quality, if mitigation is needed
Whether you already have a radon system in place or haven’t yet tested, we’ll make sure your waterproofing plan doesn’t just fix one problem while creating another. Radon levels can change over time due to weather, soil conditions, and home renovations. We recommend testing every 2-5 years, especially after significant home improvements (including air sealing and waterproofing services) or changes in occupancy.
Why Maine Radon Awareness Matters
Most of Maine is in Zone 1 on the EPA’s radon map – meaning we’re at the highest risk for naturally occurring radon gas. Approximately 36.5% of all radon tests in Maine exceed the EPA action level of 4.0 pCi/L, which underscores the importance of testing and mitigation.
If your home has:
- A dirt-floor basement or crawlspace
- Cracks in the basement floor or walls
- A sump pit or drainage channel
- Musty smells or signs of high humidity
- Open, non-radon-tight drains
…then radon is a potential concern. And if you’re doing any kind of waterproofing, it’s essential to make sure it’s done right.
Drain the Water Out Right, Radon Tight!
At Evergreen, we combine water control with air quality awareness. That means:
- Using sub-slab or sub-vapor barrier depressurization systems
- Sealing sump pits
- Properly installing vapor barriers
Homes naturally draw air up from their bottom levels into living spaces due to a building science concept known as the stack effect. That’s why depressurization in your basement or crawlspace is so important, as well as exhausting any soil gas outside of the home with a piped fan.

We’re not just here to stop puddles. We’re here to improve your entire home – starting at the ground level. You shouldn’t have to choose between a dry basement and a healthy one. With Evergreen, you get both.
