Mold Testing


When Should I Have Mold Testing Performed? 


In general the EPA does not recommend sampling unless an occupant of the space is symptomatic. When sampling is necessary it should be performed by a trained professional who has specific experience in designing mold-sampling protocols, sampling methods, and the interpretation of findings.


Sampling or mold testing should only be conducted to answer a pertinent question: examples “what is the spore concentration in the air” “or is there a particular species of fungi present in the building.”


The additional question should be asked before sampling or mold testing “what action can or should a person take upon obtaining data.”

There Are Three Types of Mold Testing Including:

1. Air Sampling

  • This is the most common form of mold testing to assess the level of mold. Sampling of the indoor areas in question and outdoor air is conducted and the results are compared. If the samples taken indoors are at lower levels than were found outside – this is an indication of acceptable air quality. If the mold levels indoors are higher than what was found outdoors –  this is an indication that there is a problem in the property and further investigation may be required.

2. Swap & Tape Lift Sampling

  • These are common methods of sampling for surface mold where we use swabs / tape to lift a sample off surfaces in question.

3. Bulk Material Sampling

  • Removing items like carpet and drywall and submitting those items to the lab is another method of sampling for mold in a property.

How Are the Inspections Performed:

Mold Testing with United Fire & Water Damage includes a comprehensive inspection of the property and areas in question. Typically, these inspections are performed by the owner of our company, who brings 17 years of experience with him to the inspections he performs. We will use many tools that we have as a restoration company – including, infrared cameras, hammer probes, hydro sensors, and penetrating and non-penetrating moisture meters.


We also have the ability to create a scope of work and estimated costs for any required remediation and / or reconstruction. Estimates are created using Xactimate estimating software – this is the same software that the vast majority of insurance companies use to estimate property losses.

Proper Mold Testing Analysis:

The sampling or mold testing analysis should follow the recommendations of Occupational Safety and Health Administration (OSHA), National Institute for Occupational Safety and Health (NIOSH), Environmental Protection Agency (EPA), and the American Industrial Hygiene Association (AIHA).


Most importantly, when a sample is taken the proper chain of custody should be adhered to. The AIHA offers lists of accredited laboratories that submit to required quarterly proficiency testing.
