Passive Radon Install Ashburn VA

Already Protected Before You Need a Fan

Not every Ashburn home needs a fan right away. For new construction or homes with lower readings and good sub-slab communication, a passive radon system creates a ready-to-activate pathway—no drilling later, no disruption down the road. Northern Virginia Radon Solutions installs passive systems that meet Virginia building codes, satisfy buyers, and upgrade easily if radon levels rise.

Passive systems work by creating a dedicated vent pipe from beneath the slab to the roof line, relying on natural air pressure differences to draw radon up and out. If post-occupancy testing shows levels above 4.0 pCi/L, we can add a fan to the existing pipe in under an hour—no new core drilling, no extra wall penetrations. Getting the pipe in right the first time saves cost and headaches later.

Is a Passive Install Right for You?

Passive installs make the most sense in specific situations. If any of these apply to your home or project, call Northern Virginia Radon Solutions for a free assessment.

If you’re building new construction and want a code-compliant, fan-ready radon rough-in from day one.
If a radon test came back between 2.0 and 4.0 pCi/L and you want a low-cost protective measure before it rises.
If you’re selling a home and a buyer is asking for radon-readiness documentation without full mitigation.
If your current system has no vent pipe and adding one now is more affordable than emergency work later.
If you’re finishing a basement and want the rough-in done before drywall goes up.
If a home inspector flagged missing radon provisions and you need a clean, documented fix.

What a Passive Install Gives You

A passive system is the smart first step for homes that aren’t yet at the mitigation threshold. Here’s what a properly installed passive system delivers for Ashburn homeowners.



Meets Virginia Code

Virginia requires radon-resistant features in new construction. Our passive installs meet current IRC and Virginia Uniform Statewide Building Code requirements, with documentation you can hand to an inspector.



Lower Cost, Full Upgrade Path

Passive installs cost less than full active mitigation. You get radon protection now without paying for a fan you may not need yet, with a clear upgrade path if the situation changes.



Add a Fan in Under an Hour

When—or if—levels require a fan, we attach it to the existing pipe stub-out. No new penetrations, no patching, no disruption. The upgrade takes under an hour.



Stays Out of Sight

We route pipe through interior walls or utility chases when possible, keeping visible runs neat and consistent with your home’s finish level. HOA-friendly and show-ready from day one.
