In Their Own Words

Mainline Inspection Services, LLC provides comprehensive video examinations of sewer lines, downspouts, drains and other pipes, empowering you to make educated decisions about major investments and repairs. Unlike other companies that offer video inspections, we are not a plumbing sales organization. Instead, we provide unbiased, objective examinations and assessments of the condition of your pipes. We do not up-sell repair work, nor do we offer repair services. We want our customers to have a complete picture of the condition of their sewer lines and other commonly overlooked infrastructure–giving them a real advantage when making decisions about home purchases, sewer line maintenance and repairs, real estate investments and more.

Before You Call Mainline Inspection Services

1. Do you take moisture readings every day and will you give me the drying log?
2. Are your technicians certified in water damage restoration?
3. Where do you think the moisture is coming from, and who fixes it?
4. Will you set up containment and negative air, and how will you protect the rest of the home?
5. How will you deal with smoke odor inside wall cavities and the HVAC ducts?

Ohio, Kentucky and Indiana have no statewide general contractor license, so check with your city or county and ask for state trade licenses for plumbing or electrical work. Also ask for proof of insurance and industry certification for the restoration crew.
