Cast iron soil stacks, drain stacks, and roof drain leaders run vertically through the walls and chases of homes, apartment buildings, and commercial properties. After decades in service they corrode from the inside, scale up, crack, and develop pinhole leaks, often showing up as stains, odors, or water damage on the floors below.
Replacing a stack the traditional way means opening walls and ceilings on every floor it passes through, then patching, painting, and cleaning up afterward. Trenchless lining renews the stack from the inside instead: we clean the pipe, then install a cured-in-place liner that forms a new, seamless pipe within the old one.
Signs your stack or roof drain is failing
- Water stains or leaks on ceilings and walls along the stack
- Sewer odor inside the building
- Rust, cracks, or pinholes on exposed cast iron
- Slow drains on upper floors
- Roof drains that back up or leak into the building during storms
How we do it
- Run an HD camera through the stack or roof drain to locate cracks, corrosion, and blockages.
- Descale and clean the pipe with high pressure hydro jetting.
- Install a cured-in-place liner through an existing access point.
- Camera the finished pipe so you can see the result.
Why line instead of replace
- No opening walls and ceilings on every floor
- Minimal disruption to tenants, residents, and businesses
- Seamless pipe with no joints to leak
- Works for residential, multi-family, and commercial buildings
