Sewer Line Cleaning & Maintenance
Sewer Line Cleaning & Maintenance in Marin, Sonoma & Napa County
Your home's sewer line is a vital part of your plumbing system, out of sight, but never out of importance. Neglected sewer lines and pipes will eventually lead to a buildup of grease, limescale, and chemical deposits. Leaks can also develop, encouraging unhealthy mold growth.
Regular sewer line maintenance ensures that waste and wastewater flow properly from your home to the municipal system or septic tank, preventing costly and unsanitary backups.
Ongaro & Sons provides comprehensive sewer line maintenance services to homeowners throughout Marin, Sonoma, and Napa counties. With decades of experience and state-of-the-art equipment, our licensed plumbers help extend the lifespan of your sewer lines and protect your property from unexpected plumbing disasters.
Why Sewer Line Maintenance Matters
Over time, your sewer line can develop issues like grease buildup, root infiltration, corrosion, or pipe misalignment. Without regular maintenance, these small issues can become major repairs, or worse, a full sewer line replacement.
Routine maintenance can:
- Detect minor clogs and corrosion before they escalate.
- Prevent tree roots from breaching your sewer pipe.
- Improve overall system efficiency and flow.
- Save money on emergency plumbing repairs.
- Extend the life of your sewer infrastructure.
What's Included in Sewer Line Maintenance?
Ongaro & Sons has the highest level of licensing available in California. Our knowledgeable professionals continue to advance their skills through extensive research and hands-on training.
You can rely on our experts to get the job done right when it comes to maintaining your sewer line and pipes. We offer the best pipe rehabilitation that includes a thorough evaluation of your sewer line to determine the appropriate action to support optimal efficiency. When you call Ongaro & Sons, maintaining your sewer line may include:
Video Camera Inspections
We insert a high-definition camera into your sewer line to visually inspect its interior. This allows us to detect hidden issues like cracks, clogs, corrosion, or invasive tree roots with pinpoint accuracy. Our non-invasive inspection gives you a clear picture of your pipe's condition, without the need to dig up your yard.
Hydro Jetting
Using a powerful stream of high-pressure water, hydro jetting scours the inside of your sewer line to remove stubborn clogs, grease buildup, tree roots, and mineral deposits. It's one of the most effective and environmentally safe methods to restore optimal flow without the use of harsh chemicals or invasive equipment.
Grease and Debris Removal
Over time, everyday waste, including food grease, soap scum, and hair, can accumulate and narrow your sewer pipes. We use professional-grade tools to safely break down and clear away this debris, helping to prevent blockages and unpleasant odors while keeping wastewater moving freely through your plumbing system.
Condition Reports
After completing your maintenance service, we provide a detailed report summarizing the condition of your sewer line. You'll know exactly what's going on underground, including any areas of concern and recommended next steps. This documentation gives you peace of mind and helps you plan future plumbing decisions with confidence.
Signs You Need Sewer Line Maintenance
If you're experiencing any of the following, it may be time to schedule a maintenance visit:
- Frequent drain clogs or slow drains throughout the home.
- Foul odors are coming from drains or the yard.
- Gurgling noises in toilets or sinks.
- Wet patches or sunken areas in your yard.
- Backups in sinks, showers, or toilets.
Don't wait for these symptoms to get worse, proactive maintenance can prevent the need for costly repairs or sewer line replacement.

The Benefits of Hydro Jetting
Hydro jetting involves using industry-approved tools to thoroughly scrub your sewer lines. It is similar to power washing, as the process flushes out the buildup inside your pipes. Hydro jetting offers more than just a powerful pipe cleaning, it can also remove blockages and support a more efficient sewer line system.
Some benefits of hydro jetting include:
- Provides a thorough cleaning
- Helps you reduce the risk of plumbing problems
- Prevents new clogs from forming

The Benefits of Pipe Descaling
Mineral and rust buildup can severely restrict water flow inside your sewer line. Pipe descaling clears these deposits from the inner walls of your pipes and delivers lasting benefits for your plumbing system.
Improves Water Flow
Descaling clears the inner walls of your pipes, allowing water to move freely through your plumbing system and improving overall performance and pressure.
Prevents Major Damage
Ignoring scale buildup can lead to cracks, corrosion, or even collapsed pipes. Regular descaling helps prevent severe plumbing issues that could result in disruptive, expensive repairs to your sewer line or water pipes.
Enhances System Efficiency
When your pipes are clean and free of obstructions, your plumbing system runs more efficiently. Descaling minimizes strain on your equipment, helping extend its lifespan and lowering your energy and water bills over time.
Protects Your Health
Scale buildup can harbor bacteria and contaminants that affect your water quality. Descaling removes these harmful elements, helping to ensure the water flowing through your pipes remains safe and clean for your household.
Supports Preventative Maintenance
Pipe descaling is a smart part of your overall plumbing maintenance plan. It allows technicians to inspect your pipes, catch early signs of trouble, and recommend solutions before small issues become major problems.
Importance of Routine Flushing
Regular system flushing helps maintain consistent water flow and removes minor sediment buildup before it causes problems. This preventative approach extends the life of your pipes and ensures your sewer line operates efficiently year-round, especially in homes with older plumbing or frequent use from large households.
