The City of Falls Church traces its name to a colonial parish church; the city's history pages record it was founded in 1734, that the settlement became a township in 1875, and was chartered as an independent city in 1948. At about 2.2 square miles by that account, Falls Church ranks among Virginia's smallest cities, so an older home near the historic core and a newer townhouse near the Metro can sit blocks apart, worth naming when you describe which room is affected.
For a house inside the Little City, tell us about the crawlspace or basement and any work done since the original construction; older brick and frame homes near the historic core may have had additions or updated systems layered in over time. In a newer condominium or townhouse near a Metro station, a shared wall or a stacked bathroom line is often the more useful detail. This page also serves the Fairfax County neighborhoods that carry a Falls Church mailing address, including Sleepy Hollow and West Falls Church; package prices there follow our Virginia schedule.
Local background: City of Falls Church: About the City.
01
In a condominium near a Metro station, plumbing for stacked bathrooms often runs through a shared chase behind a closet or wall. Record which unit reported the concern and whether the building manager has records of past repairs to that line.
02
On a compact lot near the historic core, a neighboring roofline or downspout may discharge close to your foundation. Describe drainage patterns you have observed between the houses and whether grading has changed during any nearby construction.
03
A rear addition on a wooded lot can create a lower roofline and a new interior seam where materials meet. Note when the addition was built relative to the main house and whether the seam has ever shown a stain.
Where we test in Falls Church, and what to tell us
City of Falls Church (The Little City)
In the historic core, identify whether the affected room is in the original structure or a later addition, and describe any updates made to plumbing or electrical systems nearby. A mix of older homes, condominiums and newer infill sits close together here.
Broadmont, Falls Hill
On a wooded lot with an older or mid-century house, describe the crawlspace access and any work done near the roofline. Tell us if a lower level has been finished since the house was built, and what was changed.
Sleepy Hollow, West Falls Church
For a condominium or a larger single-family house on the Fairfax County side, note whether the concern involves a shared wall, a balcony, or a window, and describe access if the building is Metro-adjacent.
No version of your result is worth more to us than another one. If the report says you need work, you choose the remediator. A separate post-remediation assessment can document conditions after the work within its agreed scope.
Virginia's residential disclosure statement advises buyers to exercise due diligence, including considering a mold assessment conducted by a business following EPA guidance. Confirm the scope and timing with your agent before settlement. A laboratory sample documents a selected place and time; it does not certify an entire home as mold-free or replace advice about your transaction.
Va. Code section 55.1-703. Current as of September 2026. General information, not legal advice.
In a condominium the scope usually follows one room, one wall or one balcony door, which makes it a targeted area for Mold Basic, with Mold Plus adding the moisture and thermal evaluation. If the concern touches a wall or balcony shared with a neighboring unit, say so, since that side may need the association's help to reach.
No. Many Fairfax County neighborhoods carry a Falls Church mailing address without being part of the independent city. Tell the office your street name so we can confirm which jurisdiction applies and which package prices to quote. The visit itself follows your address and the areas you want evaluated, not the postal city name.
Yes. Describe any renovation, rewiring, or replumbing done since the house was built, and when it happened relative to when the concern appeared. Older construction methods and newer finishes can behave differently when moisture is present, so that history helps the technician plan an accessible, targeted visit.
Describe the stain or odor's location relative to the fixtures above it, and ask your condo association who can grant access to the unit overhead. A single-unit visit can document your own space; establishing a shared source in another unit usually needs that owner's direct cooperation as well.
