We have been providing professional, friendly and qualified indoor air quality assessments and testing for families, businesses, schools, realtors and building contractors in Southwest Florida since 1999.    

We have been the leader in radon testing and mold inspections for Naples, Bonita Springs, Estero and Fort Myers, FL  for more than 15 years. 

Our acac.org Certified Indoor Environmentalist were among the first in Florida to qualify as licensed mold assessors, #2 and #5.

Mold testing (mold air sampling) alone is not used to determine if a home has a mold problem. Air Sampling alone indicates the need for further investigation and/or helps determine the extent of a mold contamination.

Homebuyers that have a "mold test" (mold air sampling) performed during their pre-purchase inspection should understand the seriousness of Aspergillusmold growth often indicated by air sampling.

Mold is always a concern for Florida homebuyers, you should understand that "mold tests" (mold air sampling) cannot tell you if a home has a mold problem. Mold air sampling results can be affected by many factors, simply vacuuming prior to air sampling can give a false "elevated" mold count.  A visual inspection (assessment) is required to determine if there is a mold contamination in a home. Your mold inspection report must document any suspected mold and identify the source or cause of the mold growth. Mold tests (mold air sampling/air quality tests) can indicate that further investigation is needed and also are used to determine the extent of a mold contamination.

Any Naples, Marco Island, Bonita Springs or Ft Myers mold assessment should meet or exceed the proposed Florida rule: 61-31.701 Minimum Standards and Practices for Mold Assessors. https://www.flrules.org/Gateway/View_Notice.asp?ID=13624346

You NEVER decide a home or structure has a mold contamination based solely on Mold Air Sampling alone.

You DO NOT call the remediation company based on just air sampling. 

Our mold assessment is to determine the sources, locations, and extent of mold growth in a building and to determine the conditions that caused the mold growth.

Our mold assessment includes a visual inspection to identify the presence of visible mold and/or excessive, unplanned moisture intrusion (past and present). Our visual assessment will include documenting suspected mold growth, musty odors, moisture damage and damp building materials and conditions. Mold assessment also includes mold air sampling to help determine the extent of any mold contamination.

 Mold Inspectors (assessors) cannot do an inspection and cleanup on same job within 12months.

Naples and Bonita Springs consumers should be aware that some local home inspector / mold inspectors are inspecting for mold and then offering to remediate the mold. They find it, clean it up and then check the cleanup themselves.  This is unethical and against Florida statutes.

Also Naples consumers should know that a mold assessment must identify (document) source of a mold problem and the extent of problem.

Radon testing in Naples communities such as Pelican Bay, Pelican Marsh, Grey Oaks, Lely and Fiddlers Creek are common during a Real Estate sale.  Our experience suggests that Condo’s have elevated radon levels more often than single family homes. Naples Homebuyers should understand that generally the seller pays for the installation of a radon mitigation system if the radon test is 4.0 pCi/l or above (the recommended action level / FL DOH & EPA).

Hundreds of homes have radon mitigation systems installed throughout  Naples,
Bonita Springs, Estero, Ft Myers communities.  We have performed over 300 post mitigation radon tests just this year (5 months).  Elevated radon levels are a health concern but generally treated as just another home repair. Collier county requires a permit to install a radon mitigation system, If someone tries to convince you a permit is not required, call the county.  Buyers need a copy of required permits to protect themselves.

As you read through our site please take advantage of the numerous links available.  We encourage you to not only educate yourself more fully as to the ongoing science and debate relating to the complex topic of indoor air quality but also to assure yourself as to the accuracy and source of any and all information presented here.  Also keep in mind that we do not perform any remediation of any kind.  In other words, we do not fix anything.  Nor should we as an inspection and testing entity.  Having Radon and Mold Professionals as your assessment and testing company assures you that we are there only to objectively assess and document the existing interior conditions of your property.  As a result, we have no potential gain or financial interest in the results.  This is a critical point to remember and is absolutely in your best interest.  Anyone, or any company, operating (in Florida) in the currently unregulated and unlicensed field of mold, that tells you they can not only inspect your property but fix a problem "if" they find one, is pretty likely to "find" one.  The new Florida law will not allow for one company to do both.  This addresses the clear conflict of interest of one company offerring both.  Currently however, as consumers, you need to be very careful about who tells you what.

Florida Statutes


468.8419 Prohibitions; penalties.
