Radon Mitigation
Radon mitigation for homes with a crawl space
Perforated drain pipes are installed underneath the home around the interior perimeter along with a radon fan. These systems paired with our heavy duty vapor barriers provide an optimal solution to keep radon out of your home.
Radon mitigation for homes with a concrete slab
Radon is pulled from underneath the slab through a pipe drilled into the foundation of the home. Typically this is done through the garage or on the side of the home.
With both systems, radon is discharged above the roof line and heavy-duty schedule 40 PVC pipe is used. This is the most effective and quietest way to discharge radon. All of our systems meet NC building code requirements.

The Silent Threat Lurking in Your Crawl Space
What if the most dangerous thing in your home was something you couldn't see, smell, or taste?
For many homeowners in Raleigh NC and surrounding areas, that threat is radon gas.
Radon is a naturally occurring radioactive gas that seeps from the ground into your home. It's the #1 cause of lung cancer for non-smokers and is responsible for over 21,000 deaths in the U.S. every year.
Because your house "breathes" air up from the ground, your crawl space or basement is the primary entry point for this dangerous gas.
What is Radon Gas?
Radon is created by the natural radioactive decay of uranium found in soil, rock, and water. It's a problem in all 50 states, and [Your Region] has areas known for higher concentrations.
Here’s the simple-but-scary truth:
It's invisible, odorless, and tasteless.
It can be found in any home: new or old, with or without a basement.
It enters through cracks in the foundation, gaps in construction, and, most commonly, through a dirt or unsealed crawl space.
The "stack effect" (where warm air rises and escapes from your home's upper levels) creates a vacuum that actively pulls this soil gas—and the radon it contains—directly into your living area.
How to Know if You Have a Radon Problem
You can't see or smell it, so the only way to know if your home has dangerous radon levels is to test for it.
The EPA recommends that all homes be tested. You can use a DIY short-term test, but for maximum accuracy, we recommend a professional long-term test or continuous electronic monitor, especially if you're buying or selling a home.
If your home's radon level is 4.0 pCi/L (picocuries per liter) or higher, the EPA urges you to take immediate action.
Our Solution: Crawl Space Radon Mitigation
As crawl space experts, we are uniquely qualified to stop radon at its source. A "one-size-fits-all" system won't work. We design a custom radon mitigation system specifically for your home's foundation.
Our systems don’t just trap radon; it actively removes it 24/7/365, giving you permanent peace of mind.
Why Consider Combining Radon Mitigation with an Encapsulation?
For homes with a crawl space, radon mitigation and a crawl space encapsulation can go hand-in-hand.
By combining services, you're not only solving your radon problem but also:
Stopping Moisture & Mold: The vapor barrier prevents mold growth and musty smells.
Improving Air Quality: You'll stop mold spores and dust mites, not just radon.
Saving on Energy: A sealed crawl space is more energy-efficient, lowering your utility bills.
Protecting Your Foundation: You'll prevent wood rot and protect your home's structural integrity.

The "Slab Myth": Why Your Concrete Slab Home Is Still at Risk
Many homeowners believe that if they have a concrete slab foundation (and no crawl space or basement), they are safe from radon gas.
This is a dangerous and common myth.
Radon gas, a cancer-causing radioactive gas, comes from the soil. A concrete slab is not a perfect, airtight barrier. Radon can—and does—find its way into slab homes through tiny, unseen pathways.
Your home's foundation type does not make you immune. The only way to know if your family is safe is to test your home for radon.
How Radon Enters Your Slab Home
Your concrete slab may look solid, but it's porous and has numerous vulnerabilities that radon gas can exploit. The "stack effect" (warm air rising in your home) creates a vacuum that actively pulls these gases from the soil into your living area.
Radon's most common entry points in a slab home are:
Cracks in the Slab: Even hairline cracks, which are a normal part of a home settling, are an open door for radon.
Utility Penetrations: The openings cut for plumbing pipes, electrical wires, and sewer lines are rarely perfectly sealed.
Control/Expansion Joints: The joint where the slab meets the foundation wall (the "cold joint") is a primary entry point.
The Solution: Sub-Slab Depressurization (SSD)
For homes with a concrete slab foundation, the most effective, reliable, and common radon mitigation method is Sub-Slab Depressurization (SSD).
This system is designed to intercept the radon before it ever enters your home.
This system runs 24/7/365, actively removing radon gas and ensuring the air you breathe inside your home is safe.
