Stains and leaks in walls
Moisture on ceilings or walls near plumbing chases can mean a failing stack.
CIPP Pipe Lining
Vertical Drain Stack Lining in Knoxville, TN
Rebuild corroded vertical drain stacks in multi-story buildings without opening walls.
- DiggingAccess points only
- MethodCured in place
- ResultSeamless pipe within a pipe
In apartments, condos, hotels, hospitals and older homes, vertical drain stacks run up through walls and chases, serving many fixtures. When they corrode or crack, the leak happens inside finished spaces and the repair usually means demolition and downtime for many occupants. Vertical stack lining renews the pipe from a top or bottom access point, keeping walls closed and residents in place.
We inspect the stack by camera, clean it with descaling and jetting tools, and install a liner using methods suited to vertical runs. Branch connections are reinstated. We plan work to limit water shutoffs and coordinate with building managers and tenants so the impact is as small as possible, and we give property managers clear scopes and documentation.
When this is the right call
Gurgling in several units
Air and noise across floors can signal a restriction in the stack.
Rust in old iron stacks
Heavy scale and thin walls call for rehab.

Drain Stack Lining: answers
Can stacks be lined while the building is occupied?
Yes, with planning. We coordinate shutoffs and notices with management.

Branch openings are reinstated after lining so each fixture works.

A well-installed liner is a long-life structural repair, though condition and use vary.

Lining is mainly for iron, clay and aging pipes, and we confirm fit after inspection.
