Local considerations
Under-slab lining
Cured-in-place lining of interior drains is common for mid-century homes and condos, often reinstating branch connections from inside the pipe.
Preparation matters
Cast iron must be descaled and cleaned before lining. Poor preparation is a leading cause of liner problems.
Terrazzo and tile floors
Many older Miami homes have terrazzo or tile that is costly to replace, which makes avoiding floor demolition especially valuable.
Before you book: checklist
- Pre-lining camera inspection with video
- Confirm which sections are lined and which branches are reinstated
- Ask about descaling method
- Post-lining camera inspection
- Confirm permit requirements
How the work is done
The standard process, step by step, plus a comparison with alternatives and its limits, is covered in our national trenchless sewer repair guide. The key limit to keep in mind: lining needs a pipe that is not fully collapsed; it follows the existing path, including sags.
Trenchless Sewer Repair in Miami: questions
Can cast iron under a terrazzo floor be lined?
Yes, if the pipe is structurally intact enough to host a liner. Lining is done from cleanouts and access points, not by breaking up the floor.
How long does a pipe liner last?
Manufacturers commonly rate cured-in-place liners for many decades. Actual performance depends on installation quality and preparation.
What happens to branch lines during lining?
After the main liner cures, branch connections are reopened with a robotic cutter. Some branches may be lined separately.
Does a condo association handle cast iron lining?
Shared stacks and common drain lines are usually the association's responsibility, while lines serving one unit may be the owner's. Check the governing documents before planning work.
