Air Quality Testing Mold Inspection

It is again the time of the year when seasonal allergies start to bother people all around but did you know that the cause of your allergies can be mold? It is part of our everyday calls to speak with homeowners and tenants about why they are getting sick inside their houses, even without any visible presence of mold and our recommendation always is to have an indoor air quality test for mold done in their houses. Let's explore more about this type of mould inspection and how it works. 

Mold Testing Business

Mold is not always visible and can be harmful to you and your family. Depending on which species of mold you have in your house it can cause allergic reactions and screw up your indoor environmental air quality. 


Our first recommendation is to always look for a professional mold inspection company to assist you with your testing services needs. With all the years of experience, those companies will provide you with a throughout service helping you understand your results and defining the next step to remediate the possible mold growth affecting the indoor air quality in your house. 


Below it is a few tips on how to pick the best mold remediation company for your project: 

  • Search for the following sentence on google: Mold testing services near me
  • Pay attention to the company's reviews and star rates. 
  • Explore their website and the services offered. 
  • Call and ask about the service: how it works, how long it takes, and what are the specifics. 


Air Quality Test for Mold: How Does it Work

After picking your professional remediation company a day and time will be scheduled for a visit, in this visit the manager/technician will visually assess your place while collecting information from you and after determining the concerned area(s) they will collect an air sample from the affected area and one from the outdoor area or in the "controlled environment". It is important to notice that if there is more than one area of concern multiple samples will be required. 

It is always necessary to have an outdoor or controlled environment sample collected because it will serve as a base to compare the number and species of mold that are floating in your house. 


Professional mold inspection companies usually use an analysis method called "spore straps" which is when a sample of the air is collected and taken to the lab to be analyzed. Results will show all the species of mold spores in your house and if the count of the outside/controlled environment is lower than the concerned area, you have mold problems in your house. 


The turnaround time to receive the results is up to you, after determining your urgency you can request from a range of available options. Industry standards are to deliver test results after 48 hours. 

Mold Air Quality Inspection: Understanding Your Results

A lot of times the most common question after completing and delivering the results of a mold air test service is how to properly read and understand the results. Any professional remediation company will help you understand and read, but in case you don't have access to this option here are three steps that can be followed to understand your report and what is it saying: 

  1. Compare the count of mold spores from the outside with the inside concerning area counting. 
  2. Anytime that an inside counting is higher than the outside one, you should pay attention to it. 


Not all types of mold spores are dangerous to human health like black mold is, research their name and their effects will always be the best practice to determine if it needs mold removal services.

Intrusive Mold inspection

If after receiving your results you determine that there is a mold infestation that needs to be dealt with you should need an intrusive mold inspection. 



Mold is not always on the surface and in a lot of cases, the origin of mold growth can be in your house structure and the mold inspector will tell what is affected and the process required to properly remediate it. A lot of times the source of the mold growth is water damage related.
