Cast Iron Pipe Lining: Trenchless Options for Corroded Drain & Sewer Pipe

What homeowners should know

• Heavy scale or corrosion may require extensive cleaning and prep.
• Missing pipe wall, collapse or severe deformation can rule out some lining systems.
• Document branch connections and how they will be reopened after lining.
• Compare lining against pipe bursting or excavation when structural condition is poor.

Start with inspection and measured scope

A good proposal should explain what the contractor saw, where the defect is, how much pipe is being repaired, why the recommended method fits the condition, what access will be created and what restoration is included.

Questions to ask before approving work

• Can I receive the camera footage and a written defect description?
• Where is the failed section located and how was it measured?
• Why is this method preferable to the alternatives on this specific pipe?
• What permits, access pits, cleanouts, branch reinstatement and restoration are included?
• What does the warranty cover, and what could void it?
