Why Does Radon Mitigation Matter?

Leesburg, 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 Leesburg, VA

Leesburg’s status as Loudoun County’s seat combines historic downtown properties with expanding suburban developments, creating a broad spectrum of radon testing and mitigation needs. The town’s geological foundation includes both ancient Piedmont metamorphic rocks and younger Triassic basin sediments, both capable of elevated radon emanation. Historic Leesburg homes feature stone foundations, crawlspaces, and cellar construction that predates modern radon-resistant building techniques, requiring specialized mitigation approaches that preserve architectural character while achieving effective radon reduction. Newer developments in areas like Lansdowne and Exeter feature contemporary construction with either passive radon systems needing activation or full basements requiring new mitigation installations. Our testing services in Leesburg address everything from 18th-century stone houses to 21st-century townhomes, conducting measurements in accordance with EPA protocols while educating property owners about radon risks specific to their structure type. Mitigation work respects Leesburg’s historic district guidelines for downtown properties while employing standard sub-slab depressurization for newer construction. System repairs and maintenance include seasonal checks of fan operation, pressure differential verification, and inspection of vent pipe integrity across the full range of Leesburg’s housing stock.

Leesburg, VA Success Story

Historic Downtown Home: Sensitive Exterior Installation & Stone Foundation Testing Historic Leesburg

The Problem
The owners of an 1840s stone townhouse in Leesburg’s historic district contacted Northern Virginia Radon Solutions after receiving elevated radon results from a long-term alpha track test — 12.6 pCi/L in the ground-level living space above a stone-walled cellar. The home had both ancient Piedmont metamorphic rock geology and a foundation type that predated any radon-resistant construction practices by over a century.

Critically, the property sat within Leesburg’s historic district, where any exterior modifications require Town approval. A standard sub-slab installation would have required drilling through original stone cellar floor — unacceptable to the homeowners and likely to the historic preservation committee.

What We Did

  • Conducted testing throughout the home including the cellar, ground level, and upper floors to map radon gradient.
  • Consulted with the Town of Leesburg historic preservation staff regarding proposed exterior system components prior to any installation planning.
  • Designed an exterior soil gas collection system using perforated pipe buried in a gravel trench along the exterior foundation perimeter — no drilling through historic stone required. Fan unit housed in a small weatherproof cabinet on the rear elevation, approved by the historic review process.
  • Discharge pipe runs vertically along the rear elevation of the home in a location not visible from the public right-of-way, meeting the Town’s visual impact requirements.
  • Applied historic-compatible mortar mix to interior cellar wall joints to reduce direct air infiltration pathways without damaging original construction.

CLIENT OUTCOME
Post-mitigation living space radon confirmed at 1.6 pCi/L — an 87% reduction. Historic preservation review was completed before work began and the installation received approval with no revisions required. The original stone foundation and cellar floor were left completely intact.

“Working in a historic district meant we needed someone who understood the constraints. They handled the historic review process themselves and didn’t touch a single original stone. That was exactly what we needed.”
