Mold, Asbestos and Indoor Air Quality Inspections in DC, Maryland and Virginia
Prescient Environmental is an independent industrial hygiene firm. We inspect, test and verify. We do not sell remediation, so the report you get is the truth about your building, written to be read by buyers, landlords, insurers and attorneys.
What we inspect and test
Residential and commercial, from a single bathroom to a 260-unit building.

Mold inspection and testing
Visual inspection, moisture mapping, air and surface sampling, and a written report within two days of lab results.

Asbestos inspection
AHERA-accredited bulk sampling before renovation or demolition, with clearance and air monitoring during abatement.

Water damage assessment
Category and extent of the loss documented room by room, so drying and demolition stop where they should.
We are not trying to sell you a remediation.
Prescient Environmental does not perform remediation. Our role is to provide objective evaluation without financial conflicts of interest.
- Our work follows IICRC S520 and other recognized industry standards relied upon by insurers, adjusters and environmental professionals.
- We review contractor scopes, remediation protocols and cost estimates so you know the quote you are holding is fair.
- Clear, defensible documentation that protects your time and your financial resources.
- We partner with licensed remediation contractors when you want a referral, and we verify their work when they are done.

"Greg was quick to respond and set us up with testing. He explained the process thoroughly and effectively. The technician Mitch was prompt and did a great job. We are not experts in asbestos, so we really appreciated the help."
"Found significant amounts of mold buried deep in the HVAC system. Was able to get my landlord to replace my HVAC system at no charge to me, and got my ducts cleaned too. Quick and the best price I could find by a long shot."
