Sewer Line Replacement Cost Factors
How much you’ll pay for a sewer line replacement in Austin, Texas, depends on a variety of factors. Here’s a closer look at how your total breaks down.
Pipe Material
The most common pipes used for sewer lines are PVC (the most budget-friendly option), ABS (the mid-range option), cast iron (higher-end), and copper (the most expensive). Each has its own cost range and preferred use case scenario; however, in Austin, PVC pipes are the most popular option for their affordability and ease of installation. Heavier cast-iron pipes are not commonly used in new Austin homes, but are still found in older properties built before the 1970s.
Here’s how sewer line replacement costs are affected by pipe material:
| Pipe Material | Average Cost per Linear Foot (Installed) | Pros | Cons |
|---|---|---|---|
| PVC | $50–$120 | Most common choice in Austin; easy to install; widely available; corrosion-resistant; 50–100 year lifespan | Not as impact-resistant; can crack from ground movement |
| ABS | $70–$150 | Good impact resistance; stronger than PVC for similar price; 50–70 year lifespan | Not as universally accepted; less thermal stability than PVC |
| Cast iron | $100–$200 | High-load bearing capacity; durable; 50–100 years | Not common in new Austin homes; can rust; more expensive option; can become blocked by mineral buildup; heavy |
| Copper | $150–$250 | Durable; corrosion-resistant; 50+ year lifespan | Most expensive option; not as commonly used for sewer laterals |
Pipe Length
The cost of running a new sewer pipe ranges from $50 to $225 per linear foot, with an average price of $140 per linear foot, which includes both materials and labor. When replacing the sewer line from your house to the main, the distance depends on your specific neighborhood and property, but an average of 40 feet is a reasonable estimate to help you determine your budget. The further your house is from the hookup, the longer the sewer pipes and the higher the costs.
Of course, the entire length of the pipe may not need to be replaced, so discuss options with your pro to get answers to all your sewer questions.
Type of Replacement
A partial replacement will be the most affordable option, with complete replacement and burst-pipe replacement ranging from $60 to $250 per linear foot. Knowing how often to clean your sewer drain can help prevent premature full replacements. Here’s how costs break down by type of sewer line replacement:
| Replacement Type | Average Cost per Linear Foot |
|---|---|
| Complete | $60–$250 |
| Partial | $50 |
| CIPP lining | $90–$250 |
| Burst pipes | $60–$200 |
Sewer Line Replacement Pro Costs
In addition to the materials needed for your sewer line replacement, Austin homeowners should consider professional labor-related costs that impact the project’s total. Here’s a closer look at the professional expenses to add to your budget.
Labor
On average, labor accounts for 50% of your total sewer line replacement costs, which includes work completed by licensed plumbers, equipment operators, general contractors, and excavation specialists. You can expect to pay between $170 and $450 per hour, depending on the Austin sewer repair pros you hire and your project’s complexity.
Permits
The city of Austin requires permits for sewer line replacements, averaging $1,150 to $2,000. Here’s a breakdown of the permit costs that you should build into your budget:
Building Sewer Tap permit: $750
Excavation permit: $400
Plumbing permit: variable cost depending on your project scope
Your sewer line pro can usually handle the permitting process for you, but it’s always wise to confirm this before starting work on your project.
Taxes
Sales tax in Austin is 7.25%, but you’re only required to pay tax on the materials portion of your project. Labor on real property repair or remodeling is not taxable in Texas.
Before starting your project, ask your contractor for a clear breakdown of all costs so you can budget accordingly and avoid surprises on your final invoice.
Does Sewer Line Replacement Increase Home Value?
Replacing your sewer line doesn’t offer a direct financial return on investment (ROI), but it still adds value to your home by avoiding future damage costs, preventing signs of a clogged sewer line, and providing peace of mind. Many prospective homeowners value a well-maintained property, and an old or failing sewer line can negatively impact your home’s resale value. To weigh your project’s value, consider your own reduced risk of damage while living in your home, and the appeal of a well-functioning sewer line to potential buyers.
