What Is A Mold Inspection?

what is a mold inspectionA mold inspection is a visual and non-intrusive inspection of a building performed by a licensed mold inspector, also known as a mold assessor.   The purpose of a mold inspection is to identify and to document any red flags that are present or conditions that could lead to mold growth.  If a mold contamination is found, the mold inspector will formulate a hypothesis about its origin, so that he can outline solutions in his mold inspection report.

Can Mold Testing Prove A Building Is Mold-Free?

can mold testing prove a building is mold freeThe answer is no! Mold testing does not prove or guarantee that a building is mold-free. Some home-buyers mistakably equate mold testing as insuring a mold-free building.

No-one can guarantee 100% that a home is mold-free, and this is why:

If we tested every room of a typical 3 bedroom home, we would have, as a minimum, 3 bedrooms, 2 baths, a kitchen, a living room, a dining room, and a laundry room.  That’s 9 rooms plus the outdoor sample making a total of 10 air samples.

When Is Mold Testing Warranted?

when is mold testing warrantedThe question as to when mold testing is warranted is dictated by the goal or objective of the homeowners or building occupants.  Many people who call for a mold inspection actually only need mold testing.  Once we start asking questions about their objective, 95% of the time we will recommend mold testing over a formal inspection of the entire building.

We recognize that every situation is different and there are times

Who Pays For A Second Post-Remediation Mold Testing?

who pays for a second post remediation mold testingWho pays for a second  post-remediation mold testing is a contingency that should be spelled out in the contract—not when this unhappy situation arise.

A second mold testing following remediation means that the mold remediation failed air clearance.  It is customary for homeowners to pay for the first mold testing following mold remediation; and, if the remediation is covered under the homeowner’s insurance policy, the cost of the post remediation testing is normally part of the remediation process and covered by insurance.

But, when the mold inspector delivers the bad news that the remediation failed air clearance, and he recommends in his report that additional mold remediation is necessary, the question becomes …

Is Mold Testing Following Remediation Necessary?

is mold testing following remediation necessaryMold testing following mold remediation, known as post-remediation testing, is an absolute must!  This verification testing  ensures that the mold remediation has been performed correctly, as evidenced by the laboratory results, which should show that the levels of mold spores are within the normal range for all types of mold spores compared to an outside control sample.

After mold remediation is completed, but before containment is removed and before any reconstruction has taken place, such as closing the wall by installing new drywall, a post remediation testing is necessary.  No matter how “clean” the area remediated may be, skipping this mold testing is not a good idea.

Is ERMI Testing Reliable To Test A Home For Mold? – Part 1

Beware! The EPA mold scale ERMI© is misleading

Charles and Danielle Dobbs

EERMI testingRMI testing, developed by the EPA to test a home for mold is, in our opinion, totally meaningless, flawed, and impractical.  This post is actually a paper we published several years ago, and we thought the information would interest our readers.  The post is in two-parts.  The first part, Is ERMI Testing Reliable to Test a Home For Mold, explains how the ERMI test was developed.  In the second part, we point out the flaws of ERMI testing.

ERMI testing involves testing a home for mold with a single dust sample.
