Home Inspections in
Loudoun County, VA
Ashburn and Brambleton new builds, Sterling originals, historic Leesburg and farms on wells in western Loudoun. We know the defect patterns of each.
Loudoun spent the last three decades turning farmland into some of the region’s largest planned communities, and most of its homes were built in that window. That means fewer century-old surprises and more builder-grade systems reaching the end of their first lifespan, stucco and siding details that didn’t age well, and new homes where builder defects matter. West of Leesburg, it is a different county: villages, farms and private wells.
Homes in Loudoun County: what we inspect
Housing eras & styles
Sterling, Sugarland Run and Cascades in eastern Loudoun are mostly 1970s–1990s townhouses and single-family homes. Ashburn Farm, Ashburn Village, Lansdowne, Broadlands and South Riding filled in from the late 1980s through the 2000s, and Brambleton, Stone Ridge and Willowsford continued the build-out. Leesburg has an 18th- and 19th-century historic district surrounded by newer subdivisions, and western Loudoun — Purcellville, Round Hill, Hamilton, Lovettsville, Waterford — is villages, farms and large-lot homes.
Water & sewer
Loudoun Water serves the designated service areas in eastern Loudoun, and the incorporated towns — Leesburg, Purcellville and others — run their own water and sewer. The county’s plan keeps central water and sewer out of the Rural Policy Area, so most of rural western Loudoun relies on private wells and septic systems.
Radon
- EPA Zone 2 Loudoun County
EPA rates Loudoun County Zone 2 (moderate), though the Virginia Department of Health has said Loudoun should be treated as high risk. Either way, finished basements are the norm in Loudoun homes, so a 48-hour test belongs on most inspections here.
Zone 2 = moderate potential (predicted average 2–4 pCi/L). Source: EPA Map of Radon Zones
New construction
Brambleton is still building out, with several national builders active, and new sections keep opening around Ashburn, Aldie and Leesburg. Loudoun new construction is where pre-drywall, final walkthrough and 11-month warranty inspections pay for themselves.
What's different about inspecting in Loudoun County
Stucco and EIFS from the boom years
Many Loudoun homes built from the mid-1990s through the 2000s used synthetic stucco (EIFS) or stucco accents. Water trapped behind the cladding at windows and roof lines is a known regional problem. We look for the warning signs and recommend invasive moisture testing by a specialist when they show up.
Large lots and drainage
Outer Loudoun’s bigger lots mean grading, swales and drainage systems matter more than in tighter developments. We trace water across the whole property and note low spots, negative grading and downspouts that dump next to the foundation.
Common findings in this housing stock
- •Moisture damage behind EIFS and stucco at windows and roof-wall intersections
- •Builder-grade HVAC that struggles to keep finished basements and upper floors comfortable
- •Original water heaters and furnaces at 15–20 years old
- •Deck ledger-board attachment problems
- •Grading and drainage deficiencies on large lots
- •Septic system age and condition in western Loudoun
- •Well water bacteria and nitrates on rural properties

Loudoun County home inspection FAQ
Do you inspect new homes in Brambleton and Ashburn?
Yes. We inspect at pre-drywall, before your final walkthrough and before the 11-month builder warranty expires. Most of what we find in Loudoun new construction is fixable — if it is on the builder’s list in time.
Can you test stucco or EIFS for hidden water?
We identify the cladding and the visible warning signs — staining, cracks, soft spots, failed sealant and missing kick-out flashing. Confirming hidden damage takes invasive probes from a stucco specialist, and we will tell you when that is worth doing.
Is western Loudoun on wells and septic?
Outside the towns, mostly yes. Add a lab water test for the well and a septic evaluation — our Rural bundle combines both with radon at a discount.
Should I test for radon in Loudoun County?
Yes, particularly with a finished basement. A 48-hour continuous test during your inspection period gives you a result in time to act on it.
Is there a travel fee for Loudoun County?
No — Loudoun is inside our standard service area, including the western towns.
