Hiring an inspector is often the first time an owner deals with asbestos at all. It is easy to hire whoever can come soonest. Speed matters, especially when water damage is waiting, but a quick inspection that misses the materials your project will disturb wastes more time than it saves.

Use the questions below on the phone or by email. Good inspectors answer them easily. Write the answers down so you can compare.

Pay attention to how the inspector talks about scope. Someone who asks what you plan to do, which rooms will be opened and whether systems will be replaced is thinking about the materials your project will actually disturb. Someone who quotes a flat number of samples before hearing about the job may be planning a generic inspection that leaves gaps.

Common questions

Can my general contractor's employee do the inspection?

Only if that person holds the appropriate current CDPHE certification. Even then, some owners prefer an independent inspector. Verify the certification with CDPHE either way.

Is a home inspector the same as an asbestos building inspector?

No. A general home inspector evaluates the house as a whole and may note suspect materials, but sampling for regulated purposes in Colorado is done by someone holding CDPHE asbestos building inspector certification.

How many samples is normal?

It depends on how many distinct materials the project touches and their size. The inspector should explain the number rather than just state it.
