Buying a Home with Cast Iron Pipes? What You Need to Know Before Closing

Buying a home is exciting — but if the house has old cast iron sewer lines, you need to be cautious. Cast iron will fail eventually, and if replacement hasn’t been done, you could be inheriting a big problem.

Here are a few things every buyer should consider:

• Don’t assume credits equal costs. If the seller offers money instead of replacing the system, push for more than the estimate amount. Underground pipe replacement can uncover surprises, and once you close, the cast iron pipe replacement cost is yours.
• Check for permits. If work was done without permits, you may end up redoing the entire job to meet code.
• Know what’s included. Spot repairs or trenchless fixes aren’t permanent solutions. A full cast iron to PVC conversion is the only way to ensure long-term reliability.
• Understand the risks. With North Texas soils, even PVC can shift over time, but replacing cast iron now removes a guaranteed failure from your future.

Pipe replacement services aren’t just another repair — they can make or break your investment.
