Cast Iron Drain Pipes in Older Homes

Cast iron drain pipes are common in older homes, valued for their durability. But time, tree-root intrusion, shifting soil, and internal corrosion can eventually turn a steady system into one that leaks, clogs, or vents foul odors.

Deciding between repair and replacement comes down to the type and extent of damage, how accessible the pipe section is, and whether the underlying cause is likely to continue. The right call can prevent repeated, costly fixes while protecting your home from water damage and sewage backups.
