Mold Testing in Denver

What Is Mold Testing?

Mold testing involves collecting samples from your property — from the air, from surfaces, or from bulk materials — and sending them to a certified laboratory for analysis. The results identify the specific types of mold spores present, their relative concentrations, and how indoor levels compare to outdoor baseline levels.

Mold testing is distinct from a mold inspection. An inspection is a visual and physical assessment by a trained professional. Testing adds a laboratory data component that can confirm the presence of mold where it is not visible, identify specific mold species, and provide documentation for insurance, real estate, or remediation purposes.

Types of Mold Testing

There are several types of mold testing available, each suited to different situations:

Air Testing (Air Sampling)

Air sampling captures a volume of indoor air and filters it for analysis. The resulting data shows what types of mold spores are present and at what concentrations. Air samples are typically compared to an outdoor control sample taken at the same time. Elevated indoor spore counts compared to the outdoor baseline suggest an active mold source inside the building. Air testing is useful for detecting hidden mold and for verifying that remediation was successful.

Surface Testing (Swab or Tape Lift)

Surface testing involves collecting a sample directly from a visible growth or suspicious surface. A swab or adhesive tape lift is applied to the area and sent to the lab for identification. Surface testing is particularly useful for confirming whether a visible discoloration is actually mold and, if so, what type. It can help determine the appropriate remediation approach when dealing with specific species of concern.

Bulk Testing

Bulk sampling involves collecting an actual piece of building material — such as drywall, wood, or carpet — from a suspected mold area. This type of testing can reveal how deeply mold has penetrated a material, helping to determine whether cleaning is feasible or whether complete removal is necessary.

When Is Mold Testing Useful?

Mold testing is particularly valuable in situations such as:

• You have musty odors or symptoms but no visible mold, and want confirmation before investing in remediation
• You want to identify whether a dark or discolored area is actually mold
• You need to confirm the mold species present, such as when Stachybotrys (black mold) is suspected
• You are completing a real estate transaction and need documentation of air quality
• You want to verify that a remediation project was successful before reoccupying a space
• You are dealing with an insurance claim and need laboratory evidence to support it

Mold Testing and Remediation Planning

Mold testing results can directly inform the remediation approach. Knowing the specific mold species present, the concentration levels, and where spore counts are elevated helps our team develop a more targeted and effective remediation plan. It also provides a before-and-after comparison to confirm that remediation achieved its goal.
