Mold Inspection Service in Northern California

In some cases, mold is readily apparent, visible right before your eyes. However, in unseen areas such as behind cabinets or within drywall, mold may lurk undetected, yet still pose health risks. This hidden mold, though out of sight, can still cause illness. Our services extend across Del Norte, Siskiyou, Modoc, Humboldt, Trinity, Shasta, Lassen, and Tehama counties, addressing mold issues wherever they may arise.

Air Quality Testing

*Most Common Air Quality tests are the most common form of mold testing in the industry. They are not perfect in their measurements but can be a great tool in determining the condition of a building. Air quality tests are usually taken by collecting a 75-liter air sample from inside the home and pulling it through a small filter. That filter is analyzed by the lab and a report is given. These tests are often compared to a similar test taken outside the area.

Tape Testing

Tape tests are best for determining the type of mold when you can visually see mold growth. These tests are less expensive than air tests but fail to provide the scope of the issue like the other tests would.

Often these tests are unnecessary when a visual inspection shows mold growth without testing.  

ERMI Testing

ERMI is widely accepted as the most accurate testing method available but is also the most expensive method. ERMI tests are taken by pulling dust and mold using a vacuum and filter system. These tests are more accurate than air quality tests but the price of the testing is sometimes as expensive as the treatment itself.
