With advanced training and extensive field experience, our team delivers objective, comprehensive evaluations of mold conditions in any environment without upselling or conflicts of interest.

What Is Mold Testing?

Mold testing is the process of collecting direct samples of mold and analyzing them to determine the species and quantity present in a building. A certified laboratory performs this analysis using methods such as microscopy, culture, or molecular identification. Samples may be collected through swabs, tape lifts, bulk material, or air sampling, depending on the situation.

Laboratory results play a critical role in guiding remediation decisions and ensuring mold is properly addressed to protect the health and safety of occupants. While mold testing provides essential scientific data, it should always be paired with a visual inspection and moisture assessment to fully understand the source and extent of mold growth.

Our Methods of Mold Testing

Mold testing is essential for identifying the presence and types of mold in a residence or business. Various methods can be used to collect mold samples and analyze them in a laboratory. Here are some common mold testing methods:

  1. Air Sampling: This method involves collecting air samples to detect mold spores in the indoor environment. Air sampling can help identify the concentration of mold spores and determine if they exceed normal levels.
  2. Surface Sampling: Surface sampling involves collecting samples from visible mold growth on surfaces using swabs, tape lifts, or bulk samples. These samples are then analyzed to identify the type of mold present.
  3. Bulk Sampling: Bulk sampling involves collecting pieces of building materials, such as drywall or insulation, that are suspected of having mold growth. These samples are analyzed to determine the type and quantity of mold present.
  4. Swab Sampling: Swab sampling uses a sterile swab to collect mold samples from surfaces. The swab is then sent to a laboratory for analysis to identify the type of mold.
  5. Tape Lift Sampling: Tape lift sampling involves pressing a piece of clear tape onto a surface with visible mold growth. The tape is then analyzed in a laboratory to identify the type of mold present.

Each mold testing method has its advantages and disadvantages, and the most appropriate method will depend on the specific situation and goals of the testing. A professional mold inspector can recommend the best type of testing for your needs.

For comprehensive mold testing services, it is essential to use specialized tools and techniques to ensure accurate results and effective remediation.

When to have a
Surface Mold Sample Taken

  • When visible or suspected mold is present.
  • Where cleanup or removal of visible mold has taken place.
  • When 3rd party will be involved in effecting repairs to ensure those repairs were completed properly.

Surface Sampling Methods

Surface sampling can be useful for differentiating between mold growth and stains of various kinds. This type of sampling is used to identify the type of mold growth that may be present and help investigate water intrusion. Surface sampling can help the interpretation of building inspections when used correctly. The following are the different types of surface samples that are commonly used to perform a direct examination of a specific location. Spore counts per area are not normally useful.

Tape (or tape-lift)
These samples are collected using clear adhesive tape or adhesive slide for microscopic examination of suspect stains, settled dust and spores. Tape lifts are an excellent, non-destructive method of sampling. The laboratory is usually able to determine if the there is current of former mold growth or if only normally settled spores were sampled.

Bulk
This is a destructive test of materials (e.g., settled dust, sections of wallboard, pieces of duct lining, carpet segments, return-air filters, etc.) to determine if they contain or show mold growth. Bulk sampling collects a portion of material small enough to be transported conveniently and handled easily in the laboratory while still representing the material being sampled. A representative sample is taken from the bulk sample and can be cultured for species identification or analyzed using direct microscopy for genus identification. The laboratory is usually able to determine if the there is current of former mold growth or if only normally settled spores were sampled.

Swab
A sterile cotton or synthetic fiber-tipped swab is used to test an area of suspected mold growth. Samples obtained using this method can be cultured for species identification or analyzed using direct microscopy for genus identification. The laboratory is usually able to determine if there is current of former mold growth or if only normally settled spores were sampled. Identified spores are generally reported as “present/absent”.

When you should consider an
Indoor Air Quality Test for Mold

  • When a recent or prior water damage event is suspected or has occurred.
  • When a “Musty” smell is noticed.
  • An occupant of the home is predisposed to respiratory distress.
  • Recent mold remediation has taken place and you want to verify the effectiveness.

Air Sampling Methods

Air samples are possibly the most common type of environmental sample that investigators collect to study bioaerosols (mold, pollen, particulates). The physics of removing particles from the air and the general principles of good sample collection apply to all airborne materials, whether biological or other origin. Therefore, many of the basic principles investigators use to identify and quantify other airborne particulate matter can be adapted to bioaerosol sampling. Common to all aerosol samplers is consideration of collection efficiency. The following are the two most common forms of air sampling methods.

Air-O-Cell Cassette
The Air-O-Cell spore trap cassette is used with a portable air pump (15 liters/minute for 1 to 10 minutes) to collect airborne aerosols including mold, pollen and other airborne particulates. Air is drawn through a small opening at the top of the cassette and spores are trapped on a sticky coated glass slide inside the cassette. These cassettes are efficient at collecting spores as small as 2.6μm.

Z5 Cassette
The Z5 spore trap is used with a portable air pump (5 liters/minute for 1 to 5 minutes) to rapidly collect airborne aerosols including mold, pollen and other airborne particulates. Air is drawn through a small slit at the top of the cassette and spores are trapped on a sticky surface on a small glass slide inside the cassette. They are efficient at collecting spores as small as 1μm.

Pre-Purchase Mold & Moisture Inspection

With the recent real estate boom and intense bidding competition here in Eastern & Coastal NC, the pressure to close on a property quickly or lose it is very real. Do not invest in a property which may have prior or present moisture damage or potential mold issues. Rushing into a purchase may be an extremely costly financial mistake in the future when issues are identified. One of the most important steps in buying a home is having a home inspection performed. While standard home inspections are useful in identify structural and mechanical damages and concerns, they are not thorough regarding moisture and mold issues. Home inspectors generally see mold as a potential liability and may fail to document questionable concerns. Home Inspectors in general will leave Mold Inspection and Mold Testing services to licensed/certified Mold Inspectors. Call Homeworks Environmental Inspections before you purchase any home in or around Raleigh, North Carolina, for mold and moisture inspections.

Post Remediation Inspection & Testing

In any large mold remediation project HEI recommends Post Remediation / Clearance Testing be performed to ensure that “Elevated” mold conditions have been corrected. A post remediation visual verification inspection should be done to ensure that the work has been performed properly. It is advised to use an independent Certified Mold Testing contractor. Following proper mold remediation guidelines is critical in ensuring that there is no further cross contamination of mold spores mold testing can confirm actual conditions. Our mold inspectors are well experienced and educated and will ensure the proper steps are taken for mold remediation inspection and testing in North Carolina.
