Tools and Techniques Used in House Mold Inspections

To properly locate and evaluate mold development in a home, qualified mold inspectors utilize a variety of specialized instruments and methods.

Below is a summary of several popular techniques:

Visual inspection

The basis of every mold examination is the visual inspection. Inspectors thoroughly inspect every component of the property with their trained eyes, paying special attention to high-risk areas such as kitchens, bathrooms, basements, and attics.

They search for outward indicators of mold development, such as discoloration, textures that are fuzzy or slimy, and water damage that may point to future mold issues.

Moisture meters

Moisture meters are portable instruments used to determine the amount of moisture present in construction materials such as wood, drywall, and flooring.

Because mold grows best in moist conditions, moisture meters aid inspectors in locating high-moisture locations that may be favorable to the formation of mold.

Cameras using infrared technology

These specialist cameras are able to identify temperature changes that may not be visible to the human eye.

Surfaces that have mild temperature variations due to mold development can be easily identified for more research using infrared cameras. This is especially helpful for finding mold in concealed spaces or behind walls.

Inspectors will use tape lifts or swabs to get samples if they see obvious mold. After that, the samples are submitted to a lab for examination in order to identify the particular kind of mold and assess its potential for damage.

Air Sample Procedure

To determine the total quantity of mold spores in the air, air sampling may be necessary in some circumstances.

Knowing the level of mold exposure and associated health problems can be aided by this. After being collected by air sampling pumps, air samples are transferred to a lab for examination.
