Why Full Replacements Beat Spot Repairs for Cast Iron Sewer Pipes

When it comes to cast iron sewer problems, many homeowners ask if they can get by with a spot repair instead of a full replacement. But here’s the truth: old cast iron pipes don’t fail in just one place. Once they start to go, the entire system is at risk.

It’s common to see companies offer “quick fixes” or trenchless spot repairs — but these are often just temporary solutions. You might fix one section, only to face another leak or blockage a few feet away. And any portion you spot-repair today will still need to be replaced later when you do a full system replacement — meaning you’ll pay for the same section twice.

At In-House Plumbing Company, we don’t offer repairs because we believe in solving the real problem — not just covering it up. We focus exclusively on full underground pipe replacement under the home and in the yard. We remove all the old cast iron in those areas and replace it with new PVC designed to last for decades.

Yes, the cast iron pipe replacement cost may seem higher upfront. But when you factor in the cost of repeat repairs and inflation, a full replacement now can save you significantly in the long run. You’re paying once — not over and over again.

When considering pipe replacement services, the smart investment is often the one that eliminates future headaches.
