About this service
What Cast Iron Sewer Pipe Replacement in Marietta, Georgia Involves
Cast iron sewer pipe replacement in Marietta, Georgia means removing corroded, cracked, or root-choked cast iron pipe and installing new PVC, ABS, or HDPE pipe in its place. We start with a sewer camera inspection to map the line, then we either dig and replace or use trenchless methods like pipe bursting to pull new pipe through the old. The goal is simple: a smooth, watertight line that drains fast and lasts decades.
Most cast iron lines in Marietta were installed between 1940 and 1975. After 50-plus years, the pipe walls scale down to half their original diameter, joints separate, and roots find every crack. If you're dealing with recurring sewer clogs or a backup that keeps coming back, you're likely looking at cast iron sewer line replacement in Marietta GA. We see it constantly in Historic Marietta and the Whitlock Avenue Historic District.

What's included
What's Included in Our Cast Iron Sewer Pipe Replacement
Every cast iron replacement we do includes the full scope: inspection, permits, excavation, new pipe, testing, and cleanup. We don't nickel-and-dime you with add-ons after the fact. If something extra comes up during the dig, we stop and show you before we do anything.
Permits and Inspections
We pull the local Georgia plumbing permit and schedule the inspection. You don't have to call the city or fill out forms. We handle the paperwork and give you the signed-off permit when the job is done.
Excavation and Pipe Installation
We dig the trench or access pits, remove the old cast iron, and install new PVC or HDPE pipe. We bed the pipe in compacted stone, set the slope at 1/4 inch per foot, and join every section with approved couplings.
Backwater Valve and Cleanout
We install a new cleanout at the property line if you don't have one, and we add a backwater valve if your line is prone to city backups. Both are included in the quote, not extra.
Testing, Backfill, and Cleanup
We pressure-test the line, run the camera one final time, and backfill in compacted lifts. We restore the surface, haul off all debris, and leave your yard ready to use. You get the final video and warranty paperwork.
How it works
Our Cast Iron Sewer Pipe Replacement Process
We run a push rod camera from the cleanout to the city main. You watch the monitor with us. We mark the depth, the material changes, and every defect on the surface with paint. This takes 30 to 45 minutes and tells us whether you need spot repair or full replacement.
You get a line-item price before we break ground. It covers excavation, pipe, fittings, permits, and restoration. If we find something unexpected during the dig, we stop and show you before doing any extra work. No change orders without your OK.
For open-cut, we use a mini excavator to dig a trench along the marked path, usually 3 to 5 feet deep. For trenchless, we dig two small pits and pull new HDPE through the old pipe with a pipe bursting machine. Most residential jobs take one to two days.
We lay new PVC or HDPE pipe on a compacted bed, set the slope at 1/4 inch per foot, and connect to the city main with approved couplings. Every joint is primed and glued or heat-fused. We install a backwater valve if your line is prone to backups.
We pressure-test the line and run the camera through it one more time. Then we backfill in lifts, compact the soil, and restore the surface. You get a copy of the final video and the permit sign-off. We haul off all debris the same day.
STEP 01Camera Inspection
We run a push rod camera from the cleanout to the city main. You watch the monitor with us. We mark the depth, the material changes, and every defect on the surface with paint. This takes 30 to 45 minutes and tells us whether you need spot repair or full replacement.
Tools & methods
Tools and Methods We Use for Cast Iron Replacement
RIDGID Sewer Camera
We use a push rod camera to inspect the inside of the cast iron line and record the video. It shows scale, cracks, roots, and bellies.
Spartan Tool Hydro Jetter
High-pressure water scours grease and scale off the pipe walls. We use it before camera inspections and to clear lines before replacement.
HammerHead Trenchless Pipe Bursting Machine
This pulls new HDPE pipe through the old cast iron, breaking it outward. It lets us replace the line without digging a long trench.
Perma-Liner CIPP Inversion Drum
We use this to install cured-in-place pipe liners when the cast iron is structurally sound but rough. It restores the pipe from the inside.
Sewer Line Locator Transmitter
We send a signal down the line and trace it from the surface. It tells us exactly where the cast iron runs and how deep it sits before we dig.
Mini Excavator
For open-cut replacements, we use a mini excavator to dig the trench. It's small enough to fit through a gate but powerful enough to dig 5 feet deep.

Cast Iron Problems We Solve in Marietta
Cast iron doesn't fail all at once. It scales, cracks, and separates over decades. Here are the problems we see most often in Marietta and how we fix them for good.
Ask a pro →Recurring clogs in the same spot
We camera the line and find the actual cause, usually scale buildup or a root mass at a separated joint. If the pipe is too far gone, we replace that section or the whole run with smooth PVC that waste can't catch on.
Sewage smell in the yard or basement
We locate the leak with a camera and a sewer line locator transmitter, then replace the damaged section. If the whole line is corroded, we replace it. We also check for stormwater infiltration while we're in there.
Slow drains throughout the house
We hydro jet the line to clear the scale and grease, then camera it to see how much pipe wall is left. If it's too thin, we replace the cast iron with new pipe sized for your home's fixtures.
Backups during heavy rain
We install a backwater valve on your main line to stop the flow from reversing. If your cast iron is also failing, we replace it at the same time so you get one fix instead of two.

Most residential cast iron sewer replacements in Marietta run $4,500 to $12,000 in 2026, depending on length, depth, and whether we open-cut or go trenchless. A simple 30-foot run at 3 feet deep is on the low end. Longer runs under driveways or mature trees push toward the high end. We give you a written price before we dig.
The telltale signs are recurring clogs in the same spot, gurgling toilets, sewage smells in the yard, and a slow drain that a snake can't fix. If your house was built before 1980 and you've had two or more backups in a year, the cast iron is likely scaled or cracked. A $250 camera inspection confirms it in under an hour.
Yes, if the pipe still holds its shape and has no major collapses. We clean the line, then pull a CIPP liner or spray an epoxy liner inside the existing cast iron. Lining costs about 30% less than full replacement and avoids excavation. We won't line a pipe that's bellied or crushed, because it will fail again.
