Radon Mitigation in Aldie, VA
Local, Certified Radon Pros Serving Loudoun County Homes
Northern Virginia Radon Solutions protects Aldie, VA families with tailored mitigation systems. Our team in Aldie, 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?
Aldie, 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 Aldie, VA
Aldie’s rural character and older housing stock present unique radon mitigation challenges compared to newer Loudoun County developments. Historic homes dating to the 18th and 19th centuries feature stone foundations, crawlspaces, and cellar construction that creates multiple pathways for radon intrusion from the uranium-rich Piedmont soils. The area’s geology includes weathered granite and schist formations known for elevated radium content, which decays into radon gas. Testing in Aldie requires specialized protocols for homes with dirt-floor crawlspaces, where we measure radon levels in both the crawlspace and living areas. Our mitigation approaches often involve crawlspace encapsulation with heavy-mil vapor barriers combined with active ventilation systems. For homes with stone foundations typical of Aldie’s heritage properties, we install exterior soil gas collection systems that don’t compromise the historic integrity of original masonry work. System repairs in this area frequently address groundwater intrusion issues that can affect radon fan operation and vent pipe integrity.
Aldie, VA Success Story
Crawlspace Encapsulation & Historic Stone Foundation Mitigation Rural Property, Aldie
The Problem
The owners of an 18th-century stone farmhouse in Aldie contacted Northern Virginia Radon Solutions after reading about elevated radon potential in Loudoun County’s weathered granite and schist formations — geology known for elevated radium content that decays into radon gas. The home featured a dirt-floor crawlspace beneath the main structure and a stone-walled partial cellar used for storage.
Testing in the crawlspace registered 22.4 pCi/L — the highest reading we had recorded in that service area. Living area levels measured 7.1 pCi/L, confirming significant radon migration from the crawlspace into the home. The stone foundation walls had numerous gaps and mortar joints providing direct radon entry pathways.
What We Did
- Installed a 20-mil reinforced polyethylene vapor barrier across the entire crawlspace floor (approximately 1,400 sq ft), lapping 12 inches up the stone foundation walls and sealed with butyl tape at all seams.
- Installed an exterior soil gas collection system rather than an interior sub-slab installation — critical for a historic stone foundation where drilling through original masonry would compromise structural integrity. Exterior perforated pipe was buried in gravel trenches at the foundation perimeter.
- Connected the exterior soil gas collection network to a radon mitigation fan mounted on the exterior wall in a weatherproof housing, with a discharge pipe extending above the eave line.
- Applied hydraulic cement to visible interior stone mortar gaps and utility penetrations where radon entry was most concentrated.
- Conducted a post-encapsulation crawlspace test and a living area test 72 hours after system activation.
CLIENT OUTCOME
Post-mitigation living area radon measured 0.8 pCi/L — a 99% reduction from the pre-mitigation crawlspace level. The historic stone foundation was fully preserved with no drilling or penetration of original masonry. The homeowners noted the crawlspace encapsulation had the secondary benefit of significantly reducing moisture and musty odors in the first floor living areas. The exterior system has weathered two full winters without any component failures.
“We were worried about drilling into the old stone walls. They found a way to fix the problem completely without touching a single original stone. The levels are incredibly low now.”
