Cast-Iron Pipe Descaling
Many older Twin Cities homes still have their original cast-iron pipes. Over the decades, rust and hard-water minerals build up inside them as “scale,” narrowing the pipe and causing slow drains and repeat backups.
Cast-iron pipe descaling grinds that buildup off the pipe walls with specialized tools and flushes it away with water. We check the pipe on camera before and after. The result is a pipe that drains like new, often without the cost of replacement.
Does Your Home Have Cast-Iron Pipes?
Cast iron was the standard drain pipe in most homes built before the 1970s.
You may have it if:
Your home was built before the mid-1970s.
You see heavy, dark gray or black pipes in your basement or utility room.
Not sure? A camera inspection will tell you exactly what’s in your walls and under your floor.
Signs of Scale Buildup
Slow drains throughout the house, not just one fixture.
Clogs that return soon after snaking.
Gurgling drains or toilets.
Sewer odors coming from basement floor drains.
Rust-colored stains on pipes or around joints.
How It Works
Before any messy cleaning starts. We protect your floors with canvas tarps during the job and clean up any mess afterward. We strive not to leave a mess.
Camera inspection. We look inside the pipe to measure buildup and check its condition.
Descaling. A specialized tool spins inside the pipe and grinds scale, rust, and debris off the walls.
Flush it out. Water washes the loosened material downstream and out of your system.
Camera check. We inspect the pipe again to check the before-and-after difference.
Why Descale Instead of Replace?
Replacing cast-iron pipe often means cutting into floors, walls, or concrete. If the pipe is still solid, descaling restores its full width at a much lower cost and with far less disruption.
Lower cost than pipe replacement.
No need to tear up your basement floor or finished walls.
Faster than replacement.
Restores full flow, often like new.
When Descaling Isn’t Enough
Badly cracked, collapsed, or worn-thin cast iron doesn’t need cleaning. It needs repair. Our camera inspection shows us where you stand. If the pipe needs repair, we’ll tell you and explain your options, including section repair or trenchless lining.
Slow drains in an older home?
Your cast-iron pipes may only need cleaning, not replacing. We’ll inspect them with a camera and show you what we find.
