Why are they a problem?
Cast Iron Sewer Pipes
Cast iron sewer pipes were commonly used in homes built before 1980 and typically have a lifespan of 50–70 years. Over time, these pipes begin to corrode from the inside out, causing cracks, leaks, root intrusion, and even complete collapse. Early signs often go unnoticed until there’s serious damage under your slab or yard.
Step 1
Leak Detection
We start with a hydrostatic test to check for leaks in your plumbing system. A drop in water level means we’ve got a leak—and it’s time to inspect further.
Step 2
Camera Inspection & Isolation Testing
Camera Inspection –
We send a high-resolution camera through your sewer lines to identify breaks, bellies, and root damage.
Isolation Testing –
We test specific sections of the line to pinpoint the exact leak location.
Marking Problem Spots –
Clear marking on the floor or ground for planning repairs.
Step 3

Once we’ve located the damage, we’ll provide a detailed quote for repairs—whether it’s a targeted spot fix or full pipe replacement. We often schedule work the same week.
If you don’t move forward with repairs, you only pay for Steps 1 & 2.
Part of Step 1 to see if you have a leak , $450

Final repair costs depends on depth, access and scope (spot repair, reroute, or full system replacement).
Temporary repairs can actually speed up pipe failure by weakening adjacent sections. If your cast iron pipes are nearing 50 years old, a full system replacement is often the most cost-effective and stress-free solution.
Top Reasons to Replace:
-
Prevent repeat leaks and ongoing repair bills
-
Protect your foundation and avoid hazardous sewage leaks
-
Increase your home's resale value and plumbing reliability
-
Each repair on cast iron weakens the pipe further, often causing new leaks. You could spend more on patches over time than on a full replacement done right the first time.
We don’t recommend it. Epoxy liners may sound like a quick fix, but they’re not a long-term solution and often hide problems rather than solving them. You’ll likely end up paying for replacement down the line anyway.
Initial detection usually takes 1–2 visits. Repairs can often be scheduled within the same or following week, depending on the severity and access.
Some homeowner insurance policies cover sudden plumbing failures—especially if they lead to property damage. We’ll help document everything so you can submit a solid claim.
We don’t just detect leaks—we fix them the right way. Our team handles everything from start to finish, including:
-
Tunneling under slab foundations
-
Crawling under pier-and-beam homes

Partnering with trusted local excavators
