Considering including sewer scopes with every inspection

We are considering including sewer scopes in our base home inspection due to the prevalence rates of defects we see in lines regardless of age and the expense associated with repairs. Has anyone else looked at moving in this direction? I think its in the client's best interests to have it performed and the 1yr sewer guard warranty with the scoping defrays the cost with extra protection for repairs over the next year. Out of all the home inspectors in Opelika, I believe we are the only Opelika home inspectors performing Opelika home inspections with sewer scopes and a sewer guard warranty to provide protection for our clients. I believe this is the direction in which the industry needs to move.
