StreamLine Pipe Relining is a Sydney-based drainage and plumbing specialist focused on repairing pipes without excavation. The company says it has served Sydney since 1989 and pioneered domestic pipe relining in New South Wales. Its services cover residential, commercial and industrial properties across Sydney, including pipe and sewer relining, trenchless pipe repair, blocked drain clearing, drainage solutions and drain camera inspections.

Using camera equipment to assess pipe damage and an epoxy-resin relining system, StreamLine repairs pipes from the inside, aiming to reduce digging, property disruption and repair time. The company states that its resin is Watermark certified, that many jobs are completed within a day, and that its relining work comes with a warranty of more than 60 years. It also offers free quotes and a relining cost estimate calculator, and promotes a price-beat guarantee. StreamLine identifies itself as a Sydney Water contractor and says it provides environmental, EPA and council-compliant solutions.
