Professional Mold Inspection & Testing in Houston, Texas

What is mold testing and how does it work?

Mold testing in Houston, Texas, offered by Reagan Environmental, is the process of assessing the presence and type of mold in a given environment. This is typically done through several methods, such as air sampling, bulk sampling, or tape lift sampling, to collect samples. These samples are then analyzed in a laboratory.

In the laboratory, the collected samples are analyzed for the presence of mold and identified at either the species or genus level. This information is important for assessing potential health risks and for determining appropriate remediation measures if necessary. Mold testing helps in identifying and managing mold issues in indoor environments.

Sample Types

Air Sampling

Indoor air quality assessments commonly employs air sampling, which can be accomplished through either viable or non-viable methods:

  • Viable Method: In the viable method, spores are gathered using agar impaction plates. These spores must be living during the sampling to enable growth and subsequent analysis.
  • Non-Viable Method: On the other hand, the non-viable method involves collecting spores using air-o-cell cassettes or allergenco-D cassettes. This method identifies both living (viable) and deceased (non-viable) mold spores during the analysis.

Tape Lift Sampling

Highly effective and non-invasive technique for sample collection.

This method involves the use of a transparent adhesive tape or slide to minutely inspect stains, settled dust, and spores. The transparent adhesive is gently pressed onto the surface, delicately removed, affixed to a clear slide or surface inside a sample bag, and subsequently submitted to the laboratory for analysis.

Bulk Sampling

Bulk sampling takes pieces of materials, like parts of buildings or segments of carpet, to check for mold. A small sample, often a 2" x 2" square piece, is collected for easy transport and handling in the lab. The lab can then identify the mold's species through culture or its genus through direct microscopy.

Swab Sampling

Swab sampling uses a sterile cotton or synthetic fiber-tipped swab to test an area of suspected mold growth. Samples are cultured for species identification or analyzed using direct microscopy for genus identification. Identified spores are typically reported as ‘present/absent.’

Carpet Cassette Sampling

Carpet cassette sampling uses a special device with an air pump to collect mold, pollen, and other particles from carpets. These samples are then checked for the type of species or group of organisms they belong to, just like the previous methods.

Understanding Your Lab Report

When reading a mold assessment report, it's helpful to understand a few key terms:

Mold Count:  This tells you how many mold spores were found, usually per a certain area or volume.

Mold Types: Lists the specific molds found; for more details on their potential health risks, check online resources.

Raw Count: The actual number of spores in the sample.

Count/M3: An estimate of spores per cubic meter of air, based on the Raw Count.

% of the Total: Shows how much a specific mold type contributes to the overall mold samples.

Common Types of Mold Identified

Here are the most common types of mold found during the average inspection:

Penicillium/Aspergillus: This is the most prevalent type of mold. While most of these species can trigger allergies, only a few are toxic. They thrive in humid areas and are often found in bathrooms, kitchens, and basements.

Basidiospores: Typically found outdoors, these molds can develop indoors in water-damaged wood, indicating wood rot or decay. They often appear after flooding or heavy rain.

Cladosporium: Another common mold found in many homes, Cladosporium thrives in poorly ventilated spaces with high moisture levels.

Curvularia: This mold is a common cause of allergic reactions.

Chaetomium: Often found growing on walls, Chaetomium suggests high humidity levels in the air.

Stachybotrys: This is a very common toxic mold, and even low levels should be a cause for concern. It can grow on various paper materials and furniture.

Memnoniella: Another highly toxic mold type that should be carefully removed if even small concentrations are detected.
