Naples Mold Inspectors

All inspector licenses are not the same.

Naples consumers should understand that Mold Assessors have a different license than Naples Home Inspectors. Home inspectors have different insurance requirements and experience requirements. In Florida Home Inspectors do not need experience to be licensed Mold Inspectors that are Certified Indoor Environmentalists have proven experience and passed an exam required by the Florida DBPR.  Most licensed  Mold Assessors / Inspectors are not CIE's and were "grandfathered" into the license and did not pass the required CIE or CIEC or CMC exam. ( http://acac.org/certify/FL.aspx )  Less than a dozen CIE's in this area and over a hundred mold inspectors licensed.

Mold Inspector identifing the source of a mold problem and the extent of the problem during their inspections sounds simple but requires experience and effort.

Visible mold can be under furniture, behind bifold doors, etc; if the inspector does not look at ALL accessible areas, he isn't doing his job.  Mold inspectors collecting  ONLY mold air samples (tests)- should recommend further investigation if air sampling is elevated.  "You cannot label a home as having a mold problem based soley on air sampling" (EPA).

Mold Tests do not replace Mold Inspection
Humidity Bloom can occur when home has elevated humidity

In Florida. Mold inspectors cannot do remediation work & inspection on same job within 12 months.

All must maintain $1 million in liability insurance with E&O coverage. Smart Consumers always hire mold inspectors that are Certified Indoor Environmentalists (CIE).  A CIE has proven experience and can write recommendations for corrections if you have a mold problem in your naples home or business.

Our Naples mold assessment (inspection) reports are always being improved but even our older reports are better than our competition.  Look at our sample inspection mold report to see what should be included as a minimum. 

This CIE certification, from The American Council for Accredited Certifications (ACAC), we believe, provides our Collier county clients an additional level of confidence in our understanding of indoor environments and the mechanical systems in place to control them. We know that our clients, as well as the educated consumer, will always appreciate hiring a Florida mold assessor that is also an ACAC Council- certified Indoor Environmentalist. Please note that all "certifications" are not the same and as a consumer, you would be wise to educate yourself on the differences.  The American Council for Accredited Certification is one of the few ANSI (American National Standards Institute) approved certification bodies in the country. The ACAC's website:acac.org is a great resource for those interested. 

Many Naples mold inspectors operate like they are in the  "wild west" / anything goes. Consumers should understand what their mold assessor MUST do.  A mold assessment /inspection (visual) report (MAR) needs to identify where the mold is, what caused the mold problem AND how to clean up the mold problem. It also must have requirements (criteria) to establish that the mold contamination has been remediated properly.    

Professional, licensed Naples mold inspectors should used Infrared cameras to help find water intrusions, then verify the area is "wet" using a moisture meter. Mold growth occurs when moisture is present (food & water).


Florida will soon begin to enforce rules for mold assessors (inspectors) in Naples, Bonita Springs, Estero, Marco Island, Ft Myers and all of Florida. It has taken several years of  meetings and public comments to have the “rules” approved.


61-31.701 Minimum Standards and Practices for Mold Assessors.

            (minimum requirements fo Mold Assessments (inspections)

468.8411 Definitions. http://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0400-0499/0468/Sections/0468.8411.html

(1) The purpose of a mold assessment is to determine the sources, locations, and extent of mold growth in a building and to determine the condition(s) that caused the mold growth.

       (2) disposable respirators (e.g. N-95) are considered the minimum level of protection for mold assessment activities


(3) A visual inspection to identify the presence of visible mold and/or excessive, unplanned moisture intrusion (past and present).

(a) A visual inspection should include all surfaces inside the building, hidden areas where moisture sources may be present, such as but not limited to, crawl spaces, attics, and behind vinyl wallpaper, baseboards, carpets, and wallboard wherever possible.

(b) Specific indicators:

1. Suspect mold growth;

2. Musty odor;

3. Moisture damage; and

4. Damp building materials and/or conditions.

(4) Sampling and Data Collection.


Your Naples mold assessor will include protocols in their report based on nationally accepted industry standards such as the S-520 and S-500.  The days of the mold inspector telling you “you have a mold problem, call the remediator to find and clean it up” should be over soon.

It is against Florida law for mold remediators to inspect (find the mold) and clean it up on the same job within 12 months.  Too many Naples mold inspectors are in a hurry and don’t want to take the time to do their job right or they just don’t know how. Remember most obtained their mold license by being ‘grandfathered”. Home inspectors and others hired lobbyists to get “grandfathered” into a mold license.

(5) An assessor shall prepare a Mold Assessment Report (MAR), to include a Mold Remediation Protocol (MRP), that is specific to each remediation project and provide the MRP to the client before the remediation begins. The MRP must specify:

(a) The rooms or areas where the work will be performed;

(b) The estimated quantities of materials to be cleaned or removed;

(c) The methods to be used for each type of remediation in each type of area;

(d) The PPE to be used by remediators.

(e) The suggested types of containment to be used

(f) The proposed post-verification procedures and criteria for each type of remediation in each area.

(6) Containment must be specified in a mold remediation protocol when the mold contamination affects a total surface area of 10 contiguous square feet or more for the project.

(7) An assessor who suggests in a MRP the use of a disinfectant, biocide, or antimicrobial coating for a mold remediation project shall indicate a specific product or brand only if it is registered by the United States Environmental Protection Agency (EPA)




Your Naples or Ft Myers mold assessment/inspection report will include what is to be inspected to determine that the mold contamination was done properly.

(8) Post-Verification Procedures and Criteria. In the MRP for the project, the assessor shall specify:

(a) The method by which the remediation is deemed complete and adequate;

(b) The criteria to be used for evaluating analytical results to determine whether the remediation project passes post-remediation verification;

(c) The post-verification shall be conducted while walk-in containment is in place, if walk-in containment is specified for the project.




You don’t ask your auto mechanic if your car will make it from Naples to California and not allow him to check / look under the hood.

Why expect your Naples mold inspector to know if a home has a mold problem when he is hired to collect air samples and not hired to perform a visual inspection to identify mold location, source of contamination and extent.

Mold air samples are used to help "clear" a mold remediation and help determine the extent of a mold problem. 

  • Some mold spores are not airborne unless someone disturbs them or there is a drastic humidity change. 
  • Some mold spores become airborne when barometric pressure changes.

Mold Air sampling (mold testing) is helpful during a mold inspection but cannot replace the need for a visual mold inspection.

Minnesota Department of Health

"Testing may be useful as part of an investigation, but it is never a substitute for a thorough visual inspection."

Poor reason for testing #1 "To find out if there is mold"

Poor reason for testing #2 "To identify what type of mold is present"

North Dakota Department of Health

Testing is not recommended as the first step to determine if you have a mold problem.

 Visible mold should never be disturbed to have mold spores show up in an air sample; this action could contaminate other areas of the structure, increasing the area needed to be remediated.

Naples Beach

Collecting mold air samples should be performed following accepted industry standards which include having a controlled environment; this does NOT mean having the doors and windows open.  Unfortunately for consumers many local mold “inspectors” fail to follow simple protocols and create false alarms over mold problems that may or may not exist.  Hiring a mold assessor that has proven his experience and knowledge is always in your best interest.  ACAC certified individuals MUST prove their experience and knowledge, no other certification requires this.

Indoor Mold and Health

A Fungus Among Us


How can I prevent mold growth in your Naples home or business?Water (moisture) is the key. Without it, mold growth cannot start, much less multiply and spread. The easiest way to prevent the mold from gaining a foothold is to control dampness. Keep your home or business clean and dry. If water stands for even 24 hours, common molds can take hold.Keeping humidity levels below 60% and venting moisture from showering and cooking to the outside are several ways to prevent the conditions that can lead to mold growth.  Other ways include:§ Clean and dry up spills within 24 hours§ Dry out wet building materials and carpets within 24 hours§ Use an air conditioner or a dehumidifier to reduce the indoor humidity levelsbelow 60%. If you have a central air conditioning system and need adehumidifier to reduce relative humidity below 60%, you should have the airconditioning system examined for problems§ Do not carpet bathrooms or basements We recommend Naples homeowners keep their humidity levels below 55% if possible.Note: While most experts suggest a relative humidity of less than 60%, below 50% is best for controlling both mold growth and dust mites. Dust mites are microscopic animals related to spiders, ticks and other mites. Dust mites eat mold and dead human or animal skin scales (flakes) and leave allergenic proteins. Dust mites reduce allergen production at these lowerhumidity levels.

Hello. This is for John Cosgrove...  In 2007, my husband and I did a complete roof tear off, including replacing the sheathing on our home. Unfortunately the roofer we hired was negligent in protecting us from water intrusion during the reroof process. We discovered after the permit was finaled that we had mold in our attic where the roofer had flooded it, but was supposed to have been taken care of it, but wasn't. John was one of the many Mold Assesors I called to give me an estimate for remedying the problem..  John was very friendly, professional and compassionate from the get go. He impressed me with his detailed knowledge of what to do and explained it step by step to me as I like to understand the entire process and what to expect. At the time Mold Assessors and Remediators could do both, but John educated me that it was a conflict of interest and that the law was changing in 2010. No other mold assessor informed me of this information. I appreciated his honesty..  John is top notch and I'd recommend him highly to anyone in need of mold assessment. There are few professionals like John who truly care about fixing your problem, but also shows compassion for the stress you're under -- I know as I've remodeled our entire home inside and out and have dealt with many contractors. John is tops in his field! Long after I have paid his company, I've called to ask for his advice on other issues and he always returns my phone calls, cheerfully and in a timely manner. I consider John a friend! April H
