Direct Exam Sampling Advantages: The direct exam can be done rapidly. Direct examination of a surface indicates all mold present in a given area. Direct sampling may reveal indoor reservoirs of spores that have not yet become airborne.

Advantages to Air sampling: It is very useful for testing the site, especially if fungal growth is not visible. Low chances of sample contamination. It is useful as a secondary tool to measure spores within the affected area or within the room of a interior space suspected of fungal growth. Note: All samples are controlled through a EMSL Chain of Custody Control (COC) directly to the Lab.

Questions to ask before you move forward.


Unfortunately, mold screening costs vary tremendously. Costs vary from company to company and mold screening costs vary based on where you live geographically. We recommend calling at least two (preferably more) mold testing companies to ask for a price quote and to the following questions:


  • What qualifications do you have to perform mold screening?
  • What certifications does your company have? What are the qualifications of your mold inspectors?
    (Note: Ask what the certification requirements for any certifications they have either as a company or the individuals who will be performing the work. There are many certifications with some requiring much more work than others. Some are probably quite simple and, unfortunately, do not connote qualification to perform a mold inspection. Further, some may require a lot of work, but are not related to nor do they touch on mold itself. Take a moment to look online to find out what's required for any certifications they list.)
  • How many mold screenings did the person who will inspect my property do in the last year? How long he/she been in this line of work?
  • What is your hourly rate?
  • What is your philosophy regarding mold sampling?
    (Tip: You're looking for conflicts of interest here. Does the mold inspector always recommend mold screening? Or are there situations where he/she says mold screening is not needed?)
  • What are the costs of each air and surface mold sample?
  • How many mold samples do you normally take?
  • Do you perform the mold sample analysis yourself? Do you perform mold remediation?
    (Tip: You're looking for conflicts of interest here. If they also perform remediation, they have a vested interest in finding mold to clean up.)
  • Do you receive any kickbacks, commissions, or referral fees for sending work to mold re-mediators?
  • Do you recommend a mold re-mediator? If so how long have they been in business and what are their qualifications?
  • How long has the mold lab been in business and what are the lab's qualifications?
