Testing & Assessment
Mold Inspection & Testing in Fairfax, VA
An assessment establishes whether mold is present, where it is growing, and how far it extends — before anyone quotes removal. A mold inspection locates moisture and growth that a room-level look would miss, reading wall cavities, subfloor, and the areas behind finished surfaces. The result is a scope: what is affected, what has to come out, and what is driving the moisture.
Most people reach this page after noticing something rather than after something broke: a smell that returns, a stain that spreads, a room that feels damp. An inspection answers what is actually there and where the moisture comes from, which is the information every later decision depends on. Several states, Texas among them, keep assessment and remediation as separate licensed roles specifically so the party identifying the problem is not the party selling the fix. Nothing here is medical advice — if you have health questions, those are for a clinician.

Frequently asked questions
The rain lasted an hour. Why is the wall still wet on Thursday?
Clay. May water that entered the marine clay is still there days later because the soil will not give it up. A basement wall is a dam against that perched layer. The storm is over; the soil is not. Waiting for a dry day on the calendar is not the same as a dry soil.
The side yard is three feet wide. Where is the water supposed to go?
Down that slot, which is why a single clogged downspout wets two houses. On lots this tight there is no lawn to buffer Accotink's overflow. Roof water hits the swale and the swale hits the buried wall, and when Accotink is high there is no unused room at the end of the slot.
A 1967 split-level. Which floor is the moisture floor?
The buried one. That elevation is a basement in everything but the listing. Original footer drains in this clay often sit collapsed. The upper floor can look fine while the lower one is a cave. Check the buried face first, not the rooms that face the street.
