Mold Inspection & Testing in Fairfax, VA

Mold inspection and testing answers two distinct questions: is mold present, and if so, where and at what concentration? These questions matter before buying a home, after water damage, when occupants report symptoms, or when you can smell mold but can't find it.

What a Mold Inspection Involves

Visual Assessment: A trained inspector examines accessible areas including attic, crawlspace, HVAC system, and areas of known or suspected moisture intrusion. Visual assessment identifies visible mold growth and moisture indicators (staining, swelling, efflorescence).

Air Sampling: Air cassette samples are collected from affected areas and outdoors (as a baseline). Laboratory analysis identifies mold species and spore counts. Elevated indoor counts relative to outdoor baseline indicate active mold growth or reservoir.

Surface Sampling: Tape lift or swab samples from visible growth identify species for remediation planning. Surface sampling does not reveal total spore load in air.

Clearance Testing After Remediation

Clearance testing confirms that remediation has reduced mold levels to background concentrations before walls are closed and rebuild begins. We recommend clearance testing by an independent inspector - not the company that performed the remediation - to avoid conflicts of interest.
