A material can look like asbestos and test negative. An ordinary-looking material can also test positive.
Shelley shares an example of a homeowner who had been told a material was definitely asbestos. After it was properly sampled, the laboratory result was negative.
Appearance can tell an experienced inspector that a material deserves attention. Appearance cannot confirm what the material contains.
Before you panic, remove it, or keep cutting into it:
Stop disturbing the material and have it professionally evaluated.
The findings should always be interpreted within the documented inspection scope and sample locations, not treated as a visual guess about the entire property.
