The Trenchless Innovations tech was very informative. Walked me through the process from start to finish. The only thing was I had to unscrew and remove the register covers before he could start. Glad I had a screwdriver.

Televised ducts under slab floor. Ducts are corrugated metal ducts and are very rusted in several areas. Suggest spin cast mortaring and spray lining with Duct Armor duct lining material.
