Stop Chasing Drain Problems. We Fix the System

If your home has cast iron drain pipes and you’re dealing with recurring clogs, backups, sewer odors, or slow drains, the issue is usually not a single blockage, it’s the pipe itself.
Cast iron is a good material. Many systems last 50–60 years. But once cast iron reaches the end of its service life, problems accelerate and become more frequent. At that point, repeated cleanings only delay the inevitable.
A cast iron repipe addresses the root cause by replacing failing sections of pipe with modern materials designed to drain cleanly and reliably.
Why Cast Iron Drains Fail
Cast iron was designed to convey water not to hold it. Over decades of use:
- Internal corrosion reduces pipe diameter
- Scale and sludge build up on rough interior walls
- Horizontal runs deteriorate first
- Pipes become brittle and prone to cracking
Most failures occur in horizontal drain lines under crawl spaces or slabs. Vertical stacks and vent pipes often remain in good condition and may not need replacement.
Signs You May Need a Cast Iron Repipe
- Frequent or recurring drain clogs
- Backups that return shortly after cleaning
- Sewer gas odors inside the home
- Gurgling toilets or drains
- Slow drainage throughout the house
- Problems moving from one fixture to another
These symptoms usually indicate system-wide deterioration, not isolated issues.
Cleaning vs. Replacing Cast Iron Pipes
Some companies attempt to rehabilitate old cast iron using:
- Cabling or augering
- Chain knockers or descaling tools
- Hydro jetting
While these methods may restore temporary flow, old cast iron becomes brittle with age. Aggressive cleaning can crack or collapse weakened pipe — especially under slabs.
If the pipe walls are already thin or heavily corroded, replacement is often the
Our Cast Iron Repipe Approach
We don’t guess. We inspect.
Our process typically includes:
- Camera inspection so you can see the condition of the pipes
- Drain clearing and electronic locating to identify problem areas
- A clear recommendation such as spot repair, partial repipe, or full repipe
In many homes, we replace deteriorated horizontal cast iron while preserving vertical stacks that are still sound. This minimizes wall damage and disruption.
Why We Replace Cast Iron with PVC
Modern PVC drain pipe offers:
- Smooth interior walls that resist buildup
- Proper drainage velocity when installed correctly
- Long service life
- Reliable performance with correct support and pitch
When PVC fails, it’s almost always due to poor installation, not the material. Experience matters.
Kitchen & Laundry Lines Matter
Kitchen sink and washing machine drains are often the worst offenders in cast iron systems.
Grease from kitchens combines with lint from modern washing machines to form heavy sludge that:
- Cables pass through without removing
- Returns quickly after cleaning
- Shortens the life of the pipe
Replacing these shared lines is often one of the highest-value improvements during a cast iron repipe.
Spot Repair vs. Full Cast Iron Repipe
Every home is different.
- Spot repairs may be appropriate for isolated failures or slab sections
- Partial repipes replace failing horizontal runs
- Full repipes eliminate recurring problems entirely
We’ll explain your options clearly with no pressure, no guesswork.
Why Experience Is Critical
Cast iron repipes are not entry-level plumbing.
A qualified contractor must understand:
- Proper pipe pitch and support
- Venting and trap design
- Drainage velocity and pressure balance
- Safe removal of cast iron
- How to avoid bellies, siphoning, and sewer gas issues
Poor workmanship leads to new problems even with new pipe.

Service couldn’t be completed due to needing a new system. We appreciate the very informative visit as well as insight that could help after a new unit install.
Plumbing Express was great. I had a failed sump pump that had partially overflowed into the basement. Nasty. Josh was the tech that did the work. He was efficient, neat and courteous. I will use Plumbing Express if I have any other plumbing needs and I will recommend them to my family and friends.
The technician was very knowledgeable and professional. I believe they did a very good job.
Ron was our second plumber from this company. The first plumber came, examined pipes and said he found no leak, even though we had experiences a large amount of water leaking from the ceiling in the finished basement. Several days later we had another leak-same area but less water the second time. Ron came in, listened to our frustration and did a more thorough inspection of the pipes and identified the problem. He was very personable and professional. On his third visit, we had several replacement pipes installed and are without leaks again. Our frustration, with the situation, was my son had used your company to replace pipes when he purchased the home and founding out not all the pipes were included with that process.
Tim arrived on time and was very professional. He took his time to explain the problem and the process it would take fix the water line.
Called Plumbing Express as tankless hot water not operating. Their website states "Get Free Plumbing Quote ". When service man showed up an looked at unit he said there would be a $207 charge to look into unit in order to give me a quote to fix unit. Due to not having hot water and time required to get another company to address the problem I agreed to pay $207 for quote. After looking in unit I was told he would not be able to fix due to age of unit and parts not available. I think he should have said parts not available when seeing model number on front of unit and I would not have wasted $207.
Outstanding customer service, we will definitely be using them in the future for any plumbing needs. Can’t thank them enough!
Extremely knowledgeable and very helpful. The team was excellent. The job was completed in 1 day with a great team. Very expressive.
Daniel Perez was great in coming out to check the problem I had with a water leak from my air conditioner line. His recommendation was correct.
Great and informative service while I was in a bind without a functioning water heater.
Plumbing Express is my go-to plumbing support team. They have fair pricing, well-vetted technicians, and a truly exceptional scheduling system. Rod, my technician, was the best. He quickly assessed the problem and gave a fair estimate, working hard to keep to the schedule. He even brought Josh along on the day of service, and the two of them worked well together. They addressed the bathtub drain repair with expertise and caused the least sheetrock damage. It was difficult to replace the broken pipe and get to the upstairs drain, but together they made it a success.
Daniel did a great job and was very professional during his service call last week!
Rod and Josh did an awesome job taking care of my clogged sinks. Knowledgable, professional and great to work with - I really appreciated their help today and would highly recommend them and Plumbing Express!
Daniel was excellent. The work he did was simply superb. I highly recommend your company and hopefully Daniel will get more and more work
Dylan from Plumbing Express came over and replaced our garbage disposal for us. It was older, had a massive leak, and needed to be replaced. He did a great job and was in and out in about 30 minutes! I also asked him to check out a potential leak I had been hearing in my ceiling. He used a thermal camera to investigate and was very honest and upfront about what he found. Rather than immediately cutting into the drywall to confirm something uncertain, he explained that the sound could simply be pipes expanding and that opening the wall might be unnecessary. He recommended monitoring the area and waiting to see if a wet spot appears, which would clearly indicate an actual leak. I really appreciated that he didn’t try to upsell or push unnecessary work. Overall, great service and a great guy. They will definitely be our go-to plumbing service from now on.
Once again we had some problems under our kitchen sink so we called Plumbing Express who were able to get us on their schedule pretty quickly after these storms Tim Robinson came out to do the job. Tim has been to our house for a number of different plumbing problems. He is personable & professional. As usual he did a great job even though this particular problem turned out to be far more difficult than anyone had expected. As frustrating as it was, Tim worked through it until he finished the job. We can't thank him enough.
Anthony was very competent, professional and friendly. He answered all my questions throughly. Highly recommend!
Frequently Asked Questions
How do I know if my cast iron pipes need to be replaced?
The clearest sign is a pattern of recurring problems that keep coming back after cleaning. Watch for these warning signs:
- Frequent or recurring drain clogs that return shortly after clearing
- Backups at multiple fixtures, not just one
- Sewer gas odors inside the home
- Gurgling sounds from toilets or drains
- Slow drainage throughout the house
These symptoms usually point to system-wide deterioration, not a single blockage. A camera line inspection shows the actual condition of the pipe walls so you can make an informed decision.
Why do cast iron pipes fail over time?
Cast iron was built to move water, not to sit in contact with it indefinitely. Over decades of use, the interior walls corrode and accumulate a rough layer of scale and sludge. This reduces the pipe’s diameter, slows drainage, and traps debris. Horizontal runs under crawl spaces and slabs deteriorate fastest because they hold standing water longer. Once the pipe walls become thin and brittle, aggressive cleaning methods like cabling or hydrojetting can crack or collapse weakened sections rather than clear them.
Should I clean my cast iron pipes or replace them?
It depends on what a camera inspection reveals. Methods like cabling, chain knockers, and hydrojetting can restore temporary flow in pipes that still have wall integrity. But if the pipe is already thin, heavily corroded, or showing structural cracks, cleaning only delays the next failure. In those cases, replacement solves the root cause rather than the symptom. Plumbing Express will show you the inspection footage and explain your options clearly, with no pressure.
Do I need to replace all of my cast iron pipes?
Not always. Every home is different. In many Metro Atlanta homes, the horizontal drain lines under the crawl space or slab fail well before the vertical stacks and vent pipes. Plumbing Express evaluates each system individually and may recommend a spot repair for isolated failures, a partial repipe of deteriorated horizontal runs, or a full cast iron repipe when recurring problems have spread throughout the system. The goal is the right fix for your home, not the largest job.
What material replaces cast iron pipes?
Plumbing Express replaces failing cast iron with PVC. Modern PVC drain pipe has smooth interior walls that resist the sludge and scale buildup that shortens cast iron’s life. It drains cleanly, holds up reliably over time, and performs well when installed with correct pitch, support, and venting. Kitchen and laundry lines are often the highest priority, since grease and lint combine to form heavy sludge that keeps returning in old cast iron.
How do you start the cast iron repipe process?
The process starts with a camera inspection so you can see the condition of your pipes firsthand. From there, the team uses drain clearing and electronic locating to confirm problem areas. You receive a clear recommendation, whether that is a spot repair, partial repipe, or full replacement, before any work begins.
