How Does Mold Inspection Detect Hidden Wall and Ceiling Mold

Investigators gather evidence in a bedroom while a detective observes during a mold inspection.

Moisture is the biggest enemy of your home, which resides silently behind the walls and ceilings, pushing your home towards an ugly, disastrous, and dangerous state without you noticing.

Moisture gives birth to mold and mildew, which damages the structure physically, destroys the aesthetics with rot marks, and affects the indoor environment with nasty odors and toxic mold particles. CA Mold Inspection suggests getting a mold inspection done if any of the signs are visible to you.

The Invisible Household Threats a Mold Inspection Can Reveal

If you have experienced an unusual, smelly odor in your home that you can’t shake, even after deep cleaning, or unprovoked, unexpected sneezing fits, headaches, or watery eyes, you may have a mold problem that can be solved after a health-risk mold inspection. 

A mold inspection is an important step in your health, as mold thrives in dark, damp areas. Unfortunately, if you neglect these hidden signs, your home’s structure may remain infested, and your family’s well-being and health may be affected.

The Strategy of Hidden Mold Detection

A certified mold inspector in Los Angeles, CA, follows a multi-layered approach to pinpointing hidden moisture and mold without ripping out walls and ceilings. Inspectors use high-tech diagnostic equipment to detect mold inside walls or ceilings, such as:

  • Infrared Thermal Cameras: 

These are cameras that can detect temperature variations throughout your walls. Wet insulation and moist wood are cooler than dry, making it easy to see hidden leaks right away with a thermal camera.

  • Moisture Meters: 

Specialized pins or ultrasonic scanners are pressed against the drywall to gauge the amount of moisture within the walls.

  • Borescopes:

A small flexible fiber optic cable camera is placed through a very small hole in the wall to give a visual assessment of what is going on in the dark interior cavity and whether any fungal growth is present.

Mold Control and Remediation Methods

Mold that develops on the back of a wall emits invisible mold spores into living areas. Full mold testing and inspection includes air sampling both within and around the property. In a laboratory, the spore counts can be compared after analyzing these samples.
