5 Types of Sewer Line Repair Methods Compared (2026 Guide)
Filter by difficulty:
1
Cured-In-Place Pipe (CIPP) Lining Creates a New Pipe Inside the Old One
🟡 intermediate 🔥 high Impact
A resin-saturated fabric liner is inserted into the cleaned pipe and cured with steam or hot air, forming a seamless pipe that lasts 50+ years.[1][5] Costs range $60-$250 per linear foot, ideal for cracks, corrosion, or leaks without full replacement.[2] Repairs complete in hours with minimal digging, reducing landscape damage by 90%.[1]
Pro tip: Clean pipes first with hydro jetting to boost CIPP adhesion by 25%, preventing liner failure in root-intruded lines.
2
Pipe Bursting Replaces the Entire Damaged Pipe Without Trenches
🔴 advanced 🔥 high Impact
A bursting head fractures the old pipe while pulling a new HDPE pipe into place, perfect for collapsed or severely damaged lines up to large diameters.[2][4] Average cost $100-$200 per foot for 50-200 ft runs, 40% cheaper long-term than excavation.[6] No-dig process finishes in 1-2 days, minimizing property disruption.[8]
Pro tip: Use for pipes over 6 inches diameter where flow capacity must stay within 5% of original to avoid backups.
3
Pull-In-Place Lining Seals Large Cracks with Fast-Curing Liners
🟡 intermediate 💪 medium Impact
A pre-shaped liner is pulled through two access points, inflated, and cured in 20 minutes with steam, sealing gaps up to 50% of pipe diameter.[1] Costs $80-$180 per foot, effective for accessible pipes with fractures but not total collapse.[1] Extends pipe life by 30-50 years with 95% success rate on straight runs.[1]
Pro tip: Limit to pipes with <3 bends; more bends increase pull force by 30%, risking liner tears.
4
Sliplining Inserts a New Smaller Pipe to Reinforce the Host
🔴 advanced 💪 medium Impact
A smaller HDPE or PVC pipe is pulled into the old one, grouted to seal voids, reducing flow capacity by 10-15% but stopping leaks.[1][2] Costs $135-$150 per foot, best for mostly intact pipes where digging is impossible.[2] Installation takes 1 day, with 40-60 year lifespan.[1]
Pro tip: Account for 10% diameter reduction; upgrade to larger host access points to maintain 90% original flow.
5
Epoxy Pipe Coating Sprays Resin for Quick Interior Restoration
🟢 beginner 👍 low Impact
Epoxy resin is spun or sprayed onto the pipe interior via robotic nozzle, curing to seal minor cracks and corrosion for 20-30 years.[2][6] Costs $50-$120 per foot, 20% less than full CIPP for short runs under 50 feet.[6] Process completes in 2-4 hours with zero excavation.[6]
Pro tip: Apply only after jetting removes 95% debris; untreated buildup cuts coating bond strength by 50%.

Bonus Tip
Get a Professional Camera Inspection Before Choosing a Method
A $200-$400 sewer camera scan reveals exact damage like root intrusion (40% of failures) or collapse, ensuring 90% method success.[1] Avoid mismatched repairs that fail in 2-3 years. Schedule annually for pipes over 20 years old to catch issues early.
