High-Margin Service
Pipe relining has some of the highest margins in plumbing. The equipment investment is significant ($30,000–$80,000), but once you're set up, material costs are low relative to what you can charge. A single full-house reline can generate $5,000–$10,000 in profit.
Compliance
Pipe relining is notifiable work in QLD as it constitutes an alteration to the drainage system. Lodge a Form 7 and provide pre/post CCTV footage to the council if requested.
