Fairfax County, VA
Post-war ramblers inside the Beltway, 1980s colonials in Burke and Centreville, Reston cluster homes and Tysons high-rises. Fairfax County inspections change with the decade the house was built.
Fairfax County is big enough that its housing reads like a timeline. The inner suburbs along the Beltway were built for the post-war boom; Reston and the planned communities of the 1960s and 1970s came next; Burke, Centreville and Chantilly filled in with townhouse and colonial subdivisions through the 1980s and 1990s; and today the growth is vertical, around Tysons and the Silver Line. A lot of Fairfax homes are now old enough that their original builder-grade systems are due, and that is where we focus.
Homes in Fairfax County: what we inspect
Housing eras & styles
Annandale, Springfield, Falls Church-area neighborhoods and the Mount Vernon corridor are rich in 1950s–1960s brick ramblers, split-levels and colonials. Reston, begun as a planned community in the 1960s, mixes townhouses, cluster homes and condos with detached homes. Burke, Centreville, Fair Oaks and Chantilly are mostly 1970s–1990s colonials and townhouses, while McLean, Great Falls and Oakton have large custom homes on big lots and Tysons and Merrifield add high-rise and mid-rise condos.
Water & sewer
Fairfax Water supplies most of the county, and the county’s wastewater division handles sewer. Even so, Fairfax County still has thousands of private wells and septic systems, concentrated in large-lot areas — Great Falls is the best known. If the listing mentions a well or septic, add a water test and a septic evaluation; on public sewer, a camera scope is worth it for older lines.
Radon
- EPA Zone 1 Fairfax County
- EPA Zone 1 City of Fairfax
- EPA Zone 1 City of Falls Church
EPA rates Fairfax County — along with the cities of Fairfax and Falls Church — Zone 1, its highest-potential category. With so many split-levels and finished basements, we treat radon testing as standard here rather than optional, and run the 48-hour monitor in the lowest lived-in level.
Zone 1 = highest potential (predicted average indoor level above 4 pCi/L). Source: EPA Map of Radon Zones
New construction
New condos and townhouses keep going up around Tysons and the Silver Line stations in Reston and Herndon, and teardown-and-rebuild custom homes are common in McLean, Vienna and the Falls Church area. Lorton’s Laurel Hill grew on the site of the old prison. New homes here are worth a pre-drywall inspection and an 11-month warranty inspection.
What's different about inspecting in Fairfax County
Stucco and EIFS on 1990s–2000s homes
Synthetic stucco (EIFS) and some hard-coat stucco installed in that era can trap water behind the cladding, especially around windows and roof-wall intersections. We look for the visible warning signs and recommend invasive moisture testing by a stucco specialist when they are present.
Big lots, long driveways, lots of water to manage
Larger lots in Great Falls, Oakton, Clifton and Fairfax Station mean more grading, more downspout runs, retaining walls and sometimes a well and septic system. We follow the water across the whole property, not just around the foundation.

Fairfax County home inspection FAQ
Should I test for radon in Fairfax County?
Yes — radon levels vary house to house even on the same street, and the only way to know is to test. A 48-hour continuous monitor can run during your inspection period so you have results before your contingency deadline.
How do I know if a Fairfax home has polybutylene plumbing?
Polybutylene is a gray (sometimes blue or black) plastic supply pipe used in many homes built from the late 1970s to the mid-1990s. We look for it at the water heater, under sinks and anywhere supply lines are visible, and flag it because many insurers treat it as a risk.
Can you tell if stucco or EIFS has water damage?
We can identify the cladding type and spot visible warning signs — staining, cracks, soft spots, missing sealant and poor flashing at windows. Confirming hidden damage takes invasive moisture probes, which a stucco specialist performs; we will tell you when that is warranted.
Are Great Falls homes on wells and septic?
Many are. Large-lot areas in Great Falls and parts of Clifton, Oakton and Fairfax Station often have private wells and septic systems. If the listing shows a well, add a lab water test; with septic, add a septic evaluation.
Do you inspect condos in Tysons and Reston?
Yes. A condo inspection covers everything inside the unit — HVAC, water heater, electrical, plumbing, windows, appliances — plus any balcony or storage you have exclusive use of. Common elements belong to the association, but we note anything that looks like a building-wide problem.
