Onyx Building Sciences

What They Do

Asbestos

Before You Call Onyx Building Sciences

1. Is your company licensed for asbestos abatement here?
2. Who takes the samples, and which lab tests them?

Ask for the contractor license your city or county requires, since Colorado has no statewide general contractor license, and use a state licensed plumber for pipe repairs. Also ask for proof of insurance and industry certification for the technicians.

They list no storefront. Ask where the business is based and whether the crew is their own.
