The average sewer line repair cost ranges from $150 to $3,800 depending on the type of damage and the repair method your plumber uses. Minor clogs and small cracks sit on the low end. Collapsed lines, deep excavation, and full-section replacements push the price much higher. Most Houston homeowners land somewhere between $1,500 and $5,000 for a standard repair.

Now let’s break down what drives these costs so you know exactly what you are paying for.
What Affects Your Sewer Line Repair Cost?
No two sewer repairs cost the same. The price depends on several factors that are unique to your home and your pipe. Here are the biggest ones.
Type of Damage
A simple clog costs far less than a cracked or collapsed pipe. Here is how common problems compare:
- Drain snaking for a basic clog: $200 to $500
- Hydro jetting for roots or heavy buildup: $350 to $1,400
- Spot repair for a single crack or break: $500 to $2,000
- Partial line replacement (1 to 15 feet): $1,000 to $4,000
- Full sewer line repair or replacement (30 to 50 feet): $2,000 to $10,000+
As a result, the severity of your problem is the single biggest factor in what you will pay.
Repair Method
How your plumber fixes the problem matters just as much as what the problem is. There are two main approaches:
- Traditional excavation: Digging a trench to access and replace the damaged section. Trenching alone adds $5 to $12 per linear foot, plus you will pay for yard and concrete restoration afterward.
- Trenchless repair: Fixing the pipe from the inside using pipe lining (CIPP) or pipe bursting. This costs $60 to $250 per linear foot but skips the yard destruction and restoration bills.
On the surface, trenchless methods look pricier per foot. However, once you add up the landscaping repair, concrete cutting, and extra labor that comes with traditional digging, trenchless sewer repair often costs less overall.
Pipe Depth and Location
Deeper pipes require more digging, heavier equipment, and additional labor hours. Sewer lines in Houston can sit anywhere from 2 to 8 feet underground. Additionally, pipes that run under driveways, sidewalks, patios, or your home’s foundation cost more to access. If your plumber needs to cut through concrete, expect to add $3 to $8 per square foot to the total.
Pipe Material
Older Houston homes often have clay, cast iron, or Orangeburg sewer lines. These materials break down faster and are more expensive to repair than modern PVC. If your plumber recommends replacing the damaged section with new pipe, the material choice also affects cost:
- PVC: $3 to $8 per foot (most affordable, corrosion-resistant)
- ABS: $3 to $11 per foot (good for cold climates)
- Cast iron: $20 to $75 per foot (durable but heavy)
- Copper: $30 to $80 per foot (longest lifespan, highest price)
Permits and Inspections
Most sewer line repairs in Houston require a city permit. Plumbing permits typically cost $30 to $500 depending on the scope of work. You may also need a camera inspection before and after the repair, which runs $125 to $500. A reputable plumber handles all of this for you so you do not have to chase down paperwork on your own.
Sewer Line Repair Cost by Common Problem
Sometimes it helps to see what specific problems cost to fix. Here are the most common sewer line issues Houston homeowners face and their typical price ranges.
Tree Root Intrusion
Tree roots are the number one cause of sewer line damage in Houston. Roots sneak into tiny cracks at pipe joints and grow until they block or crush the line. Removing roots with hydro jetting costs $350 to $1,400. However, if the roots caused structural damage, you may need a trenchless liner ($90 to $250 per foot) or a spot replacement ($500 to $2,000) to fully fix the problem.
Cracked or Offset Pipes
Ground shifting, soil settling, and age can crack your sewer pipe or push sections out of alignment. A trenchless CIPP liner can seal cracks and restore the pipe from the inside for $90 to $250 per linear foot. If the offset is severe, your plumber may need to excavate and realign that section instead.
Collapsed Sewer Line
A full collapse is the most expensive repair. The pipe has lost its shape, so lining is usually not an option. Your plumber will need to excavate or use pipe bursting ($60 to $200 per foot) to replace the collapsed section entirely. Total costs for a collapsed line typically range from $3,000 to $10,000 or more depending on the length and depth.
Bellied Pipe
A belly happens when a section of pipe sags and creates a low spot where waste collects. This causes repeated backups and slow drains. Fixing a bellied pipe usually requires excavation to lift and re-support that section. Expect to pay $1,500 to $5,000 depending on how deep the pipe sits.
How to Know if You Need Sewer Line Repair
Many homeowners do not realize they have a sewer problem until it gets serious. Watch for these warning signs:
- Multiple drains in your home are slow at the same time
- Sewage backs up into your lowest drains or toilets
- You smell rotten eggs or sewage inside your home or yard
- There are wet, soggy patches in your lawn that never dry
- One area of your grass is much greener than the rest
- Your toilets gurgle when you run water elsewhere
- You notice new cracks in your foundation or walls
If you spot any of these signs, do not wait. According to HomeAdvisor, catching sewer problems early helps you avoid sewage backups, property damage, and repair bills that grow the longer you delay.
Can You Save Money on Sewer Line Repair?
A sewer repair is never cheap, but there are smart ways to keep costs down:
- Get a camera inspection first. A $125 to $500 inspection can save you thousands by pinpointing the exact problem so your plumber does not guess or over-repair.
- Ask about trenchless options. Skipping excavation cuts out landscape restoration, concrete repair, and extra labor days.
- Do not ignore early warning signs. A $350 hydro jetting today can prevent a $5,000 replacement next year.
- Compare estimates. Get at least two or three quotes so you understand the fair price for your specific job.
- Ask about financing. Many plumbers offer payment plans so you can fix the problem now and pay over time.

When Does Repair Turn Into Replacement?
Sometimes a repair is not enough. If your sewer line is over 50 years old, has damage along its entire length, or keeps breaking down after repeated fixes, a full sewer line replacement may be the smarter long-term move.
A camera inspection will tell you whether a targeted repair can solve the problem or if the whole line needs to go. Either way, knowing the full picture helps you make the right call for your home and your budget.
