Table of Contents

TLDR

What Is Sewer Line Unclogging

What Is Sewer Line Unclogging

Sewer line unclogging is the process of removing blockages in the main pipe that carries wastewater from your home to the city sewer or septic system.
 Minor clogs involve grease, debris, or paper buildup. Severe blockages often come from tree roots, collapsed pipes, or years of buildup.
 When left untreated, these clogs lead to sewage backups, foul odors, and yard flooding.

Average Cost to Unclog a Sewer Line in 2025

Average Cost to Unclog a Sewer Line in 2025
  • National average: $150 to $800

  • Louisiana average: $200 to $600

  • Simple clog: $100 to $300

  • Severe blockage with roots: $500 to $800+

  • Sewer line repair if damage is found: $1,000 to $4,000

Emergency calls at night or on weekends add $100 to $300 more. Hydro jetting, which uses high-pressure water, often costs between $400 and $1,000.

Factors That Affect the Cost

Factors That Affect the Cost

Several factors influence the total price:

  • Length and depth of sewer line

  • Type of clog (grease vs tree roots vs collapsed pipe)

  • Method used (snaking, hydro jetting, camera inspection)

  • Labor rates in your area

  • Accessibility of cleanout points

  • Emergency or after-hours service fees

Sewer Solutions advises homeowners to get a camera inspection before major work. Inspections usually cost $100 to $300 but prevent unnecessary repairs.

Methods to Unclog a Sewer Line and Their Costs

Methods to Unclog a Sewer Line and Their Costs
  • Snaking: $150 to $300, best for minor clogs
  • Hydro jetting: $400 to $1,000, ideal for tree roots and heavy buildup
  • Chemical treatments: $50 to $150, often temporary and not recommended for major clogs
  • Trenchless repair: $1,500 to $4,000+ if a clog reveals pipe damage

Snaking is quick and affordable. Hydro jetting gives longer-lasting results but requires specialized equipment. For severe cases, especially when you need to remove tree roots from sewer line, professionals often combine hydro jetting with a camera inspection to ensure the pipe is fully cleared and undamaged.

Signs You Need Sewer Line Cleaning

Signs You Need Sewer Line Cleaning
  • Slow draining sinks and tubs

  • Toilets gurgling when other drains are used

  • Sewage backup in basement or lowest-level drains

  • Bad odors coming from drains

  • Wet spots or sinkholes in your yard

If you notice more than one of these signs, your main sewer line likely needs professional cleaning.

Sewer Line Maintenance to Avoid Costly Clogs

Sewer Line Maintenance to Avoid Costly Clogs
  • Schedule regular inspections every 1 to 2 years

     

  • Never pour grease, oil, or fat down drains

     

  • Avoid flushing wipes, hygiene products, or paper towels

     

  • Install root barriers near trees close to sewer lines

     

  • Consider annual hydro jetting if you live in older neighborhoods with root problems

     

Preventive maintenance costs less than dealing with a full clog. Sewer Solutions often sees clients spend $200 annually on maintenance instead of thousands on emergency repairs.

DIY vs Professional Sewer Line Unclogging

DIY vs Professional Sewer Line Unclogging

DIY methods sometimes work for minor clogs. Renting a plumbing snake costs $50 to $100. Store-bought chemicals cost less than $50 but often fail on major clogs.

Professional plumbers charge more but bring experience and proper equipment. A misstep with DIY can damage pipes, leading to repairs that cost thousands. Call a professional if:

  • Multiple drains back up at once

  • Yard flooding is visible

  • Toilets gurgle or overflow after other fixtures are used

Louisiana prices are slightly lower than national averages because of regional labor rates, but emergency or root-related jobs often push costs higher.

FAQs

How much does it cost to snake a sewer line?

Many modern sewer systems, including ATUs, come with alarms that notify you of issues such as low air pressure or system malfunctions. If your alarm goes off:

  1. Do not ignore it. The alarm is designed to alert you to problems that may need professional attention.
  2. Contact a professional: Reach out to a licensed service provider or installer to inspect the system and perform necessary maintenance.

Recognizing the early signs of a failing sewer system can help you avoid costly repairs and health hazards. Look out for these common indicators:

  • Slow drains: If your sinks, showers, or toilets drain slowly, it may indicate a clog or backup in your septic system.
  • Unpleasant odors: Foul smells around the drain field, septic tank, or inside your home could mean there is a problem with the system.
  • Standing water or wet spots: If you notice soggy patches of ground near the septic tank or drain field, this could be a sign of overflow or system failure.
  • Backed-up sewage: A severe backup of sewage inside the house is a major red flag that your septic system is malfunctioning and needs immediate attention.
  • Lush green grass over the drain field: If the grass over your drain field is unusually green and lush, it may indicate an excess of untreated wastewater.

If you notice any of these symptoms, it’s important to call a professional sewer service provider for an inspection and possible repair.

As a sewer system owner, there are a few key responsibilities to ensure your system works properly and lasts longer:

  • Keep the area clear: Avoid placing vehicles, heavy equipment, or structures over your septic tank or ATU. Roots or pests (like fire ants) should be kept away from the system.
  • Monitor the system: Regularly check the system’s operation and make sure the control panel is functioning properly. If your system has an alarm, ensure it’s working and responds to malfunctions.
  • Avoid overloading: Use water efficiently, and avoid flushing non-biodegradable items or harmful chemicals (like bleach or disinfectants).
  • Professional service only: Always have licensed professionals perform inspections and repairs. Unauthorized servicing can cause damage or void your warranty.

The frequency of sewer system pumping depends on the type of system you have and how much water your household uses. Here are some general guidelines:

  • Septic tanks: Pump every 3-7 years, depending on your water usage and the size of your tank.
  • Aerobic Treatment Units (ATUs): These systems typically require less frequent pumping due to their more efficient treatment, but you may still need to pump every 5-10 years or as needed.

 

Regular maintenance checks are crucial. If you notice odors, slow drainage, or unusual discharges, it may be time for an inspection or pump-out.

For your sewer system to function efficiently, it’s important to use only approved products. Here’s a list of safe items for your system:

  • Household cleaners: It’s safe to use household cleaners in moderation, provided they follow the directions on the label. Avoid excessive use, especially with bleach or harsh chemicals.
  • Toilet paper: Only use biodegradable toilet paper designed for septic systems.
  • Laundry detergent: Use sewer-safe detergents in recommended amounts.

 

However, certain products should never go into your sewer system, including:

  1. Large amounts of bleach or disinfectants that kill bacteria
  2. Feminine hygiene products, diapers, and other non-biodegradable items
  3. Cooking oils, grease, coffee grounds, or shrimp shells
  4. Chemical drain cleaners
  5. Plastics, rubber, and large paper products

 

These items can harm the system’s bacteria or cause blockages, reducing efficiency and increasing maintenance needs.

Both Aerobic Treatment Units (ATUs) and septic tanks treat wastewater, but they use different methods:

  • Septic Tank: A septic tank relies on anaerobic bacteria (bacteria that do not require oxygen) to break down waste. The wastewater is held in the tank where solids settle, and liquids are filtered out. Over time, sludge builds up at the bottom of the tank, requiring periodic pumping.
  • Aerobic Treatment Unit (ATU): An ATU uses aerobic bacteria (bacteria that require oxygen) to break down organic waste. Air is pumped into the unit, promoting a more efficient biological process. This method results in cleaner effluent (treated wastewater) and often requires less frequent pumping.

 

Key Differences:

  • Aerobic systems (ATUs) are generally more efficient, producing cleaner treated water and requiring less maintenance.
  • Septic tanks are simpler but can require more frequent pumping and can produce less treated effluent.
