National Environmental Consulting Firm for Due Diligence, Risk Assessment & Site Remediation
CRB delivers fast, defensible environmental insight that helps lenders, developers, and property owners move forward with clarity and confidence.
Built for Transactions That Can’t Afford Uncertainty
Delays, unexpected contamination, and unclear reporting can stall deals, disrupt financing, and create unnecessary liability.
Lenders, developers, and commercial real estate stakeholders rely on clear, defensible environmental due diligence to move forward with confidence.
Common issues that stall transactions:
Delayed environmental reports impacting closing timelines
Unexpected contamination discovered too late
Reports that don’t hold up to lender or regulatory scrutiny
In most transactions, that process begins with a Phase I Environmental Site Assessment — the industry standard for identifying risk, protecting liability, and maintaining deal momentum.

FREQUENTLY ASKED QUESTIONS
Your Questions.
Clear Answers.
We know environmental due diligence can raise complex questions. Here are the answers to some of the questions we get most.
-
A Phase I Environmental Site Assessment (ESA) is a standardized report that evaluates a property for potential environmental risks and liabilities.
It includes a site inspection, historical records review, regulatory database search, and interviews to identify Recognized Environmental Conditions (RECs). Phase I ESAs are typically required during commercial real estate transactions to meet lender requirements and qualify for liability protections under ASTM E1527-21 and EPA All Appropriate Inquiry (AAI) standards.
-
A Phase I ESA is typically required before purchasing, refinancing, or developing commercial real estate.
Lenders almost always require it to assess environmental risk before issuing a loan. It is also commonly used by developers, investors, and attorneys to identify potential liabilities early and avoid costly delays during transactions.
-
Most Phase I Environmental Site Assessments are completed within 2 to 4 weeks.
Timing can vary depending on property complexity, historical use, and data availability. Expedited timelines may be available for time-sensitive transactions.
-
If environmental concerns are identified, the next step is typically a Phase II Environmental Site Assessment.
A Phase II involves targeted sampling of soil, groundwater, or vapor to confirm whether contamination is present. From there, remediation or risk management strategies can be developed to keep the project moving forward.
-
A Phase I ESA identifies potential environmental risks, while a Phase II ESA confirms them through testing.
Phase I is non-invasive and research-based. Phase II involves fieldwork and laboratory analysis to determine if contamination exists and to what extent.
-
Environmental due diligence is the process of evaluating a property for environmental risks that could impact value, financing, or liability.
This includes Phase I ESAs, Phase II testing, regulatory compliance reviews, and remediation planning. It is a critical step in commercial real estate transactions to protect buyers, lenders, and stakeholders.
-
An Indoor Air Quality (IAQ) assessment evaluates the air inside a building for contaminants that may impact health, safety, or operations.
This can include testing for mold, airborne particulates, volatile organic compounds (VOCs), humidity issues, and ventilation performance.
-
IAQ testing should be performed when there are odors, health complaints, visible mold, or concerns about ventilation.
It is also commonly conducted in offices, healthcare facilities, schools, and veterinary clinics where indoor environments directly impact occupants.
-
Common IAQ issues include mold growth, poor ventilation, excess humidity, VOCs, and airborne contaminants.
These issues can lead to occupant discomfort, health concerns, and potential liability if not properly addressed.
-
Yes, environmental consulting services can be performed nationwide depending on project scope and location.
Our firm supports clients across multiple states with consistent reporting, regulatory knowledge, and project coordination.
