Cast Iron Pipe Replacement in Delaware County, PA

Most Delaware County homes built before 1980 have cast iron sewer pipes. They last 50-75 years, then corrode from the inside out. Here’s how to replace them without tearing up your property.

Signs Your Cast Iron Pipe is Failing

• Rust-colored water in toilets or sinks
• Recurring clogs (interior rust narrows the pipe)
• Sewage smell in basement or yard
• Cracks in foundation (from shifting soil around corroded pipe)
• Patches of extra-green grass (sewage leaking underground)

Cast Iron Pipe Replacement Options

Option 1: CIPP Pipe Lining ($5,000-$12,000)

Best for: Pipes with <50% corrosion, small holes, separated joints

We insert a resin liner inside the existing cast iron pipe. It cures into a new pipe with a 50+ year lifespan. No excavation required.

Option 2: Pipe Bursting ($8,000-$15,000)

Best for: Severely corroded pipes, collapsed sections

We pull a bursting head through the old cast iron pipe, breaking it apart while pulling a new HDPE pipe behind it. The old pipe fragments stay underground.

Option 3: Traditional Excavation ($12,000-$25,000)

When required: Pipe under house foundation, multiple 90-degree bends

Dig a 3-4 foot trench from house to street, remove old pipe, install new PVC or HDPE pipe, backfill, restore landscaping/driveway.

Why Cast Iron Pipes Fail

Cast iron corrodes from the inside out due to:

• Hydrogen sulfide gas (from sewage) reacts with iron to form sulfuric acid
• Interior rust builds up, narrowing the pipe until it clogs constantly
• Corrosion holes develop, causing leaks
• Complete failure after 50-75 years
