In Their Own Words

Professional home inspection services. Veteran owned and operated serving the greater central Indiana region

Written by the business on its public profile. We have not verified these claims.

Before You Call Tier One Inspection Services

1. Do you also do remediation? If so, who checks your work?
2. How many air samples will you take, and will you take an outdoor control sample?
3. Is your company licensed for asbestos abatement here?
4. Who takes the samples, and which lab tests them?
5. Is your firm certified under the federal lead renovation rule?

Ask for the contractor license your city or town requires, since Indiana 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.
