Radon Mitigation in Round Hill, VA
Local, Certified Radon Pros Serving Loudoun County Homes
Northern Virginia Radon Solutions protects Round Hill, VA families with tailored mitigation systems. Our team in Round Hill, VA understands Loudoun’s high radon potential, basement-heavy homes, and tight new construction that can trap gases—especially during winter’s closed-house conditions. We design neat, HOA-conscious installations for townhomes, single-family homes, and condos, delivering reliable reductions that fit your property and budget.
Why Does Radon Mitigation Matter?
Round Hill, VA sits in an EPA Zone 1 area, where geology commonly releases radon into basements and slabs. Many neighborhoods feature finished lower levels and tight envelopes that elevate concentrations when windows stay closed in winter and during summer AC season. Professional mitigation reduces long-term lung cancer risk, protects resale value, and satisfies real-estate requirements, giving you verifiable results backed by local expertise. Crawlspaces, sump pits, and new-build rough-ins can all be integrated for better performance. A properly sized fan and sealed pathways keep levels down year-round.

Fun Facts About Round Hill, VA
Round Hill’s small-town character in western Loudoun County features homes where radon testing addresses geology at the transition between Piedmont crystalline rocks and Blue Ridge foothills. The area’s older housing stock includes varied foundation types—stone foundations, crawlspaces, and basements—reflecting multiple construction eras. Testing in Round Hill serves village properties and surrounding homes, conducting measurements that follow EPA protocols while accounting for each foundation type’s specific radon entry characteristics. Our mitigation installations implement exterior soil gas collection for historic stone foundation homes, crawlspace encapsulation with comprehensive vapor barriers and active ventilation, and sub-slab depressurization for basement construction. Round Hill’s elevation and proximity to Short Hill Mountain don’t eliminate radon concerns—underlying geology remains the primary factor influencing radon levels. System maintenance includes seasonal inspections of fan operation, verification that vent pipes remain clear and structurally sound through weather changes, and checking that monitoring devices function properly.
Round Hill, VA Success Story
Western Loudoun Small Town: Stone Foundation with Active Exterior System Round Hill, Loudoun County
The Problem
A Round Hill homeowner in an older home with a stone foundation tested at 9.8 pCi/L. The partial basement was used for storage and as a workshop. The home sat at the Piedmont-Blue Ridge geological transition — an area where both crystalline and mountain-derived sediment geology contribute to radon generation. The stone foundation had visible mortar gaps and no original waterproofing.
The homeowner wanted mitigation without altering any original stone construction.
What We Did
- Conducted diagnostic testing in the basement and first floor to map the radon gradient.
- Designed an exterior soil gas collection system using perforated pipe buried along the exterior foundation perimeter.
- Fan mounted on the rear exterior wall in a weatherproof enclosure. Discharge above the roofline.
- Applied compatible lime mortar — matching the original stone and mortar composition — to the most significant interior gap areas, preserving historic character while reducing direct air infiltration.
- Conducted post-installation testing.
CLIENT OUTCOME
Post-mitigation test confirmed 1.9 pCi/L in the basement and 0.8 pCi/L on the first floor. Original stone was fully preserved. The lime mortar application matched the existing mortar appearance closely enough that the repairs are not distinguishable from original construction.
“I use the basement as a workshop so the air quality matters to me directly. The radon is now very low and the stone was completely preserved. Couldn’t ask for more.”
