Sewer line replacement is the single biggest plumbing expense most DFW homeowners face. Quotes range from $4,000 to over $25,000 — for what looks like the same job. Here's what's inside those numbers and how to read a sewer quote.
Quick numbers (DFW, 2026)
| Approach | Cost range | Time | |---|---|---| | Trenchless pipe bursting (40 ft) | $7,500 – $14,000 | 1 day | | Trenchless CIPP lining (40 ft) | $9,000 – $16,000 | 1 day | | Traditional dig and replace (40 ft, easy) | $5,000 – $10,000 | 2–3 days | | Traditional dig and replace (40 ft, under driveway/landscaping) | $10,000 – $25,000 | 3–5 days | | Yard cleanout install | $1,200 – $2,500 | 1 day |
Why the wild range?
Sewer pricing depends on six big variables:
1. Length and depth
A 30 ft replacement at 5 ft depth is straightforward. A 75 ft replacement at 12 ft depth (because of grade) is a different job entirely. Plano and Frisco lines often run deeper than Dallas lines.
2. Access
Front yard with grass on top? Easy. Crossing a driveway, sidewalk, mature trees, or under a deck? Each adds days and dollars.
3. Trenchless vs. open cut
- Trenchless pipe bursting — pulls a new HDPE pipe through the old one, breaking it apart. Two access pits instead of a trench. Best for straight runs.
- Trenchless CIPP lining — pulls a resin-saturated liner through and cures in place. Best when the existing pipe path is intact.
- Open cut — dig a trench, replace, backfill. Always available, sometimes the only option.
Trenchless saves your landscaping, driveway, and patio. Open cut destroys them and you pay to put them back.
4. Material
- PVC — most common today, $5–$8/foot installed
- HDPE (trenchless) — pulled in one continuous piece, no joints
- Cast iron — almost never spec'd for new residential
5. Permits and inspections
DFW cities all require permits. Typical costs:
- Dallas: $250–$600
- Plano: $300–$700
- Frisco: $400–$900
- Allen / McKinney: $250–$550
Inspection is required before backfill. Add 1 day to the schedule.
6. Cleanouts
Most DFW homes built before 1990 don't have a yard cleanout — it's required by current code on a replacement. Add $800–$1,500.
What sewer line replacement should include
Look for these line items on any quote:
- ✅ Camera inspection before and after
- ✅ City permit and inspection fees
- ✅ Replacement pipe (PVC schedule 40 or HDPE)
- ✅ Yard cleanout install if missing
- ✅ Concrete saw-cutting if needed
- ✅ Backfill with proper compaction
- ✅ Surface restoration (sod or concrete patch)
- ✅ Written warranty (10+ years on pipe, 1+ year on labor)
If a quote doesn't include surface restoration, you'll be paying a second contractor to put your yard back together.
Will my insurance cover it?
Standard homeowners policies don't cover sewer line failure. Many insurers offer a service line endorsement for $40–$100/year that does — covers up to $10,000 typically.
If you've had multiple plumbing issues and don't have this endorsement, get it. Today.
Should I really go trenchless?
Not always. Trenchless works great when:
- The path is reasonably straight
- The existing pipe isn't crushed flat
- There's room for the entry/exit pits
Open cut wins when:
- The pipe path includes a sharp bend
- The pipe is collapsed or offset by 50%+
- The job is short (under 25 ft) — open cut is sometimes faster
A camera inspection up front tells you which is the right choice.
The "warning signs" that lead to replacement
- Recurring backups (especially with rain)
- Slow drains in multiple fixtures simultaneously
- Sewer smell in the yard or basement
- Patches of unusually green grass over the sewer line
- Foundation cracks parallel to the sewer line path
If you're seeing two or more, get a camera inspection before things get worse.
How to evaluate sewer quotes
- Get a camera inspection on a CD or USB. Watch it. Make sure the plumber can show you the actual problem.
- Get 2–3 written quotes that include all the line items above.
- Ask whether the price includes restoration.
- Ask about the warranty in writing.
- Verify the company has a sewer license, not just a plumbing license. (Texas separates these.)
Real DFW examples
- 40 ft straight run, front yard, Garland: $8,200 (trenchless)
- 65 ft, crossing a driveway and a tree, Plano: $18,500 (open cut)
- 35 ft, yard only, Mesquite: $5,800 (open cut)
- 80 ft pipe bursting under a backyard pool deck, Frisco: $14,200 (trenchless saved $25k+ in deck removal)
