Drain Specialist explained
Damaged drains need repair before causing flooding or structural problems. Three main methods: lining, excavation, or patch repair. Expect to pay £400–£3,500 for UK drain repair.
What Does the Work Involve?
Specialist assesses damage via CCTV. Drain lining: epoxy-resin liner pulled through pipe, cured in place. No digging. Excavation: dig down to pipe, remove section, install new. Disruptive. Patch repair: smaller area localized lining. Quickest but limited.
