Buying a Home With Cast Iron Pipes? Know the Risks

If you’re buying a North Texas home built before 1986, there’s a good chance it still has cast iron sewer lines. Before you sign, know what you’re walking into.

Old cast iron pipe replacement is often unavoidable. Failing pipes cause backups, leaks, and even foundation movement. An underground pipe replacement may cost tens of thousands — and once you own the home, it’s your responsibility.

Some buyers accept a seller credit, planning to handle the work later. But remember: estimates are not guarantees. Hidden conditions can increase the cast iron pipe replacement cost once excavation begins. If you go this route, negotiate extra room in case costs rise.

The safest move is having the work addressed before closing with a permitted cast iron to PVC conversion. Pipe replacement services done right give you confidence that your dream home won’t turn into a nightmare.
