Radon Mitigation in Ashburn, VA
Local, Certified Radon Pros Serving Loudoun County Homes
Northern Virginia Radon Solutions protects Ashburn, VA families with tailored mitigation systems. Our team in Ashburn, 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?
Ashburn, 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 Ashburn, VA
Radon concerns in Ashburn stem from the area’s position in the Piedmont geological province, where granite bedrock contains naturally occurring uranium deposits. Homes in planned communities like Ashburn Farm and Broadlands built in the 1990s-2000s often feature full basements with poured concrete foundations—prime entry points for radon gas migration. Our technicians regularly service radon mitigation systems in Ashburn’s newer construction, where builders implemented passive radon systems that require activation with fan units. We conduct testing throughout Ashburn Village and Ashburn Farms neighborhoods, where soil gas surveys reveal elevated uranium content in the underlying metamorphic rock formations. System maintenance in this area typically involves inspecting active soil depressurization fans mounted in attics or garage spaces, checking the pressure differential gauges that confirm proper suction, and ensuring that PVC discharge pipes remain clear of seasonal debris accumulation.
Ashburn, VA Success Story
Passive System Activation & First-Time Radon Test Ashburn Farm Subdivision
The Problem
A first-time homebuyer in Ashburn Farm purchased a 2002 colonial and assumed the PVC pipe stubbing up through the basement slab was a plumbing vent. Their home inspector noted it as a passive radon rough-in but did not test for radon. Six months after move-in, the homeowner read a county health advisory about radon in Loudoun County’s Piedmont geological zone — where granite bedrock contains naturally occurring uranium deposits — and called Northern Virginia Radon Solutions for a baseline test.
Preliminary testing revealed an indoor radon concentration of 6.8 pCi/L — nearly twice the EPA’s 4.0 pCi/L action level. The passive system installed by the builder was functioning as designed but was insufficient to depressurize the sub-slab aggregate enough to keep radon from migrating into the living space.
What We Did
- Conducted a short-term EPA-protocol radon test using a calibrated continuous monitor, confirming the 6.8 pCi/L reading over 48 hours.
- Performed sub-slab diagnostic testing by drilling a small probe hole adjacent to the existing passive pipe and measuring pressure field extension — confirming the aggregate layer had adequate communication for single-point depressurization.
- Activated the passive system by connecting an inline radon mitigation fan to the existing 3-inch PVC stub in the basement. Fan was mounted in the attic space above the passive pipe run, keeping it away from living areas and shielded from weather.
- Sealed all visible foundation cracks and pipe penetrations in the basement floor using polyurethane caulk before activating the fan.
- Installed a U-tube manometer on the vent pipe so the homeowner can visually confirm the system is maintaining negative pressure at a glance.
CLIENT OUTCOME
Post-mitigation test conducted 48 hours after fan activation confirmed radon levels reduced to 0.9 pCi/L — an 87% reduction. The homeowner was particularly relieved given they had been using the basement as a home office throughout the six-month period before testing. The system has operated without interruption and the manometer has read consistently in the correct range at every follow-up check.
“I had no idea what that pipe in my basement was for. Now I understand how the whole system works and my levels are well below the safe threshold. Wish I’d tested on move-in day.”
