Home inspections catch code violations and major defects. ESG's indoor air quality assessments catch what they are not designed to find: odors, mold and moisture intrusion. Independent, peer-reviewed results your clients can act on inside the due diligence window.

Timing matters. Testing early in due diligence leaves room to gather remediation quotes before the window closes.

Why add an assessment

An inspection and an assessment answer different questions

Home inspections and IAQ assessments overlap in places, but they are built to find different things. Your buyers benefit from both.

What a home inspection covers

Inspections primarily seek to identify code violations and major building defects: the visible, structural, systems-level picture of the property.

Code violations
Major building defects
Visible and accessible conditions

What an ESG IAQ assessment adds

Assessments concentrate on factors an inspection is not designed to measure, and the data speaks to the current state of the air your client would be living in.

Odors, mold and moisture intrusion
Current air quality data, lab analyzed
Potential problems from hidden issues
A certified determination of whether suspect growth is mold, which only an Indoor Environmental Professional can make

Timing

Test early in due diligence

If there are suspected issues, it is in your client's best interest to test immediately. Estimates and contractor scheduling can take weeks, and the goal is to have every quote in hand before due diligence ends.

Contract signed

Schedule the assessment as soon as due diligence begins, especially if anything about the property raises questions.

Assessment and sampling

ESG visits the property, evaluates odors, mold and moisture concerns, and collects samples for laboratory analysis.

Results and quotes

Findings come back in a peer-reviewed report. If remediation is needed, your client starts gathering contractor estimates right away.

Decision before the deadline

Ideally all quotes are received before due diligence ends. If they are not, your client may want to discuss extending the due diligence period.

The referral relationship

A referral that protects your reputation

When you refer ESG, your client gets an independent answer. We have never performed remediation, so we have no incentive to find problems that are not there, and no reason to soften findings that are. Every report is peer reviewed by two certified professionals before it goes out.

If the assessment does find a problem, we do not leave your client stranded. Remediation should be performed by trusted companies, so we provide a list of remediators based on industry-standard qualifications and help your client understand which standards the work should meet.

Realtor FAQ

Questions realtors ask us

How is an IAQ assessment different from a home inspection?

A home inspection primarily identifies code violations and major building defects. An IAQ assessment concentrates on odors, mold and moisture intrusion. The data collected speaks to the current state of the air quality and flags potential problems that may come from hidden issues a general inspection is not designed to find.

When during a transaction should testing happen?

As early in due diligence as possible, and immediately if there are suspected issues. It can take weeks to receive cost estimates and schedule contractor work, and ideally your client has every quote in hand before due diligence ends. If not, an extension may be worth discussing.

Who can determine whether suspect growth is mold?

Only an Indoor Environmental Professional is certified to determine whether suspect growth is mold. ESG's certified consultants make that determination with lab-analyzed sampling, and every report is peer reviewed by two certified professionals.

Can ESG help if the assessment finds a problem?

Yes. Remediation should be performed by trusted companies, and we can provide a list of remediators based on industry-standard qualifications. We also help your client understand which industry standards the work should meet, and we can verify the work independently once it is done.
