Services & What We Do
Mold Testing
Air sampling and lab-analyzed results.
Moisture Intrusion Investigations
Identify sources of unwanted moisture.
Visual Interior Inspections
Thorough visual evaluation of the property.
Post-Remediation Verification
Confirm remediation was successful via measured tests and data.

Mold Inspections
We always start by taking a detailed background and history of the property. We also talk about your concerns and how we can help you. We then formulate an inspection plan, taking into account the areas of concern.
With an infrared camera, handheld moisture meter, and temperature and humidity device, we can look for signs of moisture and any physical potential mold growth.
A detailed report will be written, outlining our findings and any recommendations we may have. If water or mold damage is suspected or visualized, we can then recommend next steps.
Mold Testing
We use specialized instruments to take “air samples” of your indoor areas, if desired. We take an exterior air sample as a baseline comparison.
The areas and number of samples are usually determined on site after inspection. If any visible “suspected” mold is found, we can also take a physical tape lift sample of the surface and that will give us a bigger picture along with the air sampling.
After sampling is complete, we then hand-deliver to our independent microbiology laboratory to be analyzed. You'll receive a report and/or summary of findings.
