Was Your Austin-Area Home Built 1950-1986? Your Sewer Pipes Could Be at Risk

If you own an older home in Austin, Georgetown, Round Rock, or Pflugerville, there’s a hidden problem lurking beneath your slab foundation — aging cast iron sewer pipes. These pipes, common in homes built between 1950 and 1986, have a limited lifespan and may already be causing costly damage without you realizing it.

Why Are Cast Iron Sewer Pipes a Problem?

Cast iron sewer pipes were the industry standard for decades due to their durability and strength. However, they aren’t built to last forever. The typical lifespan of cast iron pipes is about 50 years, after which they begin to deteriorate, corrode, and develop leaks.

If your home was built:

• Between 1950 and 1969 — Your pipes are likely past their prime and should be replaced immediately to avoid raw sewage leaks, flooding, and structural damage.

• In the 1970s — Replacement is probably needed within the next 5 to 10 years before major failure happens.

The key takeaway: It’s not if your cast iron sewer pipes will fail, but when.

What Happens When Cast Iron Sewer Pipes Fail?

Once corrosion sets in, cast iron pipes can develop small cracks that quickly turn into leaks. These leaks aren’t just minor annoyances; they can cause:

• Foul odors emanating from your yard or basement

• Raw sewage leaking into your yard or under your home’s slab

• Damage to your home’s foundation and floors

• Frequent backups and plumbing issues

Ignoring these problems can lead to severe property damage and expensive emergency repairs.

Why You Should Completely Replace, Not Just Repair

You might wonder why you can’t just fix leaking spots as they appear. The truth is, patch repairs on cast iron pipes are temporary band-aids that often make the problem worse.

Every repair weakens the surrounding metal, creating two new leak points near the repair site over time. These stopgap fixes add up and drain your wallet, while failing to address the root cause: the pipe system is deteriorating as a whole.

Replacing your entire cast iron sewer line all at once is the safest and most cost-effective long-term solution. It protects your home, saves you from repeated costly repairs, and ensures your plumbing is up to modern code.

What About Trenchless Pipe Relining for Cast Iron Pipes?

You may have heard of trenchless epoxy pipe relining as a “less invasive” alternative to replacement. However, for cast iron sewer pipes, relining often isn’t a reliable fix:

• Before applying epoxy, the pipes must be cleaned and prepped—this sanding and cleaning process is very harsh and can cause weakened pipes to rupture or crack further.

• If the pipes are too deteriorated, relining can’t be completed, and you’ll still need a full replacement anyway.

• Even when applied, epoxy liners can trap corrosion underneath, causing ongoing damage and reducing pipe diameter, which restricts sewer flow.

• Unlike full replacements, epoxy relining isn’t inspected or regulated by any governmental agency, so quality and durability aren’t guaranteed.

• Plus, relining doesn’t fix external corrosion, which is often the primary issue with old cast iron pipes.

In short, trenchless relining may sound like a quick fix, but it’s often just a costly delay before a full replacement becomes unavoidable.
