Cast Iron Pipe Replacement in Franklin & Nashville, TN
Cast iron pipe replacement renews the corroded cast iron sewer lines common in older Nashville and Franklin homes, where decades of interior scaling and rust have narrowed and weakened the pipe.
What It Is
Because more than half of Nashville homes were built before 1983, cast iron failure is one of the most common sewer problems we see in Middle Tennessee.
How It Works — Our Process
Our cast iron replacement process renews the line cleanly:
A Camera Inspection
A camera inspection that documents the scaling, corrosion, and any cracks in the cast iron
A Method Decision
trenchless lining or pipe bursting when the line allows, excavation when it does not
Permit Pull Where Required
Permit pull where required
Installation
Installation of new, corrosion-resistant pipe to replace the cast iron
A Final Camera Pass
A final camera pass documented for your records
When You Need It
Replace cast iron when a camera inspection shows heavy interior scaling, corrosion that has thinned the pipe wall, cracks, or recurring backups in an older home. Pre-purchase inspections of pre-1975 Nashville homes frequently reveal cast iron that needs attention.

Frequently Asked Questions
Why does cast iron pipe fail?
Cast iron corrodes and scales from the inside over decades, narrowing the pipe and eventually cracking or collapsing. Most cast iron lines in Nashville's older homes are now near or past their service life.
Can corroded cast iron be lined instead of replaced?
If the pipe still holds its shape, CIPP lining can renew it without digging. If it is collapsed or too thin, pipe bursting or excavation replaces it. The camera inspection tells us which.
How much does cast iron pipe replacement cost?
Trenchless methods run $180–$200 per linear foot (includes prep — hydro jetting and descaling) for lining or $150–$180 per linear foot for bursting; a traditional dig-and-replace is $8,000–$10,000 (80-ft typical residential, depending on depth, transitions, and fittings).
My home is from the 1960s — should I be worried about cast iron?
Cast iron from that era is often at the end of its life. A camera inspection is the competitively priced way to know its condition before a backup forces an emergency repair.
