However, if you have a “Sewer Backup” or “Service Line Coverage” endorsement on your policy, you may be covered. Always have your plumber provide a detailed report for your insurance adjuster.

depends on where the pipe is. There is a “Sticker Price” vs. a “Total Project Cost” to consider.
The Upfront Cheapest (Shallow & Accessible): If your sewer line is only 2–3 feet deep in a grassy yard, Traditional Trenching is usually the cheapest upfront. You pay roughly $50–$150 per linear foot for a crew to dig a ditch, swap the old pipe for PVC (the most affordable material), and bury it.
The Long-Term Cheapest (Deep or Under Landscaping): If your pipe is deep or runs under a driveway/expensive garden, Trenchless Pipe Bursting is the winner. While the plumbing bill might be $150–$250 per foot, you save thousands by not having to replace your concrete driveway or professional landscaping.
The “Surgical” Cheapest (Isolated Issues): If a camera inspection shows that only a 5-foot section is broken (often due to a single tree root), a Spot Repair is your best bet. Instead of a $10,000 full replacement, you might pay $1,500–$3,500 to fix just the affected area.
Rerouting is the “Bypass Surgery” of plumbing. Instead of breaking through your foundation to fix a leaky pipe, we abandon the old pipe in the ground and run a brand-new line through your walls or attic.
Average 2026 Cost: $1,500 to $7,000+
The price varies wildly based on the scope:
Single Line Reroute (e.g., to a kitchen sink): Usually $1,500 – $3,500. This covers the new pipe and the labor to “fish” it through the walls.
Whole-House Reroute (Repipe): For older homes with failing copper or galvanized lines, a full reroute typically starts at $6,000 and can reach $15,000+.
Protects the Slab: You don’t have to jackhammer your foundation, which can lead to structural cracks later.
Preserves Flooring: If you have expensive tile or hardwood, rerouting saves you from having to replace it.
Texas Clay Factor: Since our soil shifts so much, any pipe not in the ground is a pipe that won’t snap when the earth moves.
Next Step for You: If you are smelling sewer gas or seeing a spike in your water bill, the first move is a Camera Inspection (usually $150–$400). This is the only way to know if you can get away with a cheap spot repair or if you need a full reroute.
