Signs Your Sewer Line Needs Repair

You can’t see your sewer line fail because it runs under your property, out of view. However, plumbing fixtures and drains in your home can offer some clues about sewer damage.

For example, waste flowing from your floor drain, shower, or toilet is a warning sign that your sewer line may need repair. It is a good idea to have it inspected at least once a year.

Other signs your sewer line needs repair:

If more than one drain in your home, such as sinks, tubs, or showers, is draining slowly, it’s often a sign of a deeper issue in your main sewer line. A single slow drain might just be a localized clog, but widespread drainage problems typically point to a larger blockage or damage.

Toilets that frequently clog or overflow, especially without a clear reason, could indicate a problem in your sewer line. This is often due to a blockage or break that prevents wastewater from flowing freely. If plunging doesn’t help, it’s time for a professional inspection.

Unpleasant sewer smells coming from your drains or around your property are not normal. These odors often signal that a cracked or leaking sewer line is allowing gases to escape. Don’t ignore it, these fumes can be hazardous and warrant immediate attention.

Unusually soggy, sunken, or bright green patches in your yard, especially along the sewer line path, can indicate a leak. Sewage may be seeping into the soil, creating health hazards and damaging your landscaping. This is a common warning sign of a compromised pipe.

If you hear gurgling noises from your drains, it may mean air is trapped due to a blockage in your sewer line. These sounds often accompany other symptoms, like slow drainage or backups, and should be checked by a plumbing professional promptly.

Ongaro Sewer Repair Process

At Ongaro & Sons, we begin every sewer repair with a thorough, noninvasive inspection. Using a high-definition sewer camera, we feed a flexible scope through your sewer line to pinpoint the exact location and cause of the problem, whether it’s a blockage, crack, corrosion, or invasive tree roots. This step allows us to assess the extent of the damage and determine the most effective repair strategy.

Once the issue is identified, our experienced technicians will explain your options. Whenever possible, we recommend trenchless repair methods to minimize disruption to your property. Techniques like pipe lining or pipe bursting allow us to repair or replace damaged pipes without extensive excavation.

If a traditional repair is necessary, we take extra care to protect your landscaping and restore your property as neatly as possible. Throughout the process, we maintain open communication, keep the work area clean, and ensure all repairs are code-compliant and built to last.

With decades of experience and a commitment to quality craftsmanship, Ongaro & Sons ensures your sewer line is repaired efficiently, safely, and with long-term performance in mind.

Sewer Repair Options

We can diagnose the problem accurately and provide the best solution after looking at the inside of your sewer line. We offer traditional and trenchless methods for repair and replacement.

Traditional Sewer Repair Method

We excavate in your front yard to access the damaged sewer line and repipe areas that need it. This method may involve digging in your driveway or uprooting some landscaping to uncover it.

We know how stressful and inconvenient sewer problems can be. Our qualified pros complete repairs efficiently and safely. We make every effort to finish the job as quickly as possible while minimizing disturbances.

Trenchless Sewer Repair Method

The trenchless repair process is less invasive than the traditional method. We dig two holes at each end of the damaged sewer line rather than excavate your property. Repair options include pipe lining or pipe bursting techniques.

Pipe lining involves placing a lining and resin coating inside the damaged sewer line. The materials adhere to the inside of the pipe and harden within a few hours.

The trenchless pipe bursting method uses a tool that destroys the damaged sewer line as it simultaneously places a new pipe.

Prevent Sewer Repairs With Maintenance

Ongaro & Sons recommends an annual cleaning to keep waste from building up in your sewer line. We offer hydro jetting, which sends a powerful blast of water through the sewer pipe to flush sludge, grease, and other materials.

Hydro jetting is ideal for a structurally sound sewer line. We can suggest an alternative cleaning method for an older, weakened pipe that cannot withstand high-pressure water jetting.

You can help keep your sewer pipe free of clogs. Avoid putting nonflushable products in your toilet, and refrain from pouring grease down sink drains.

Ongaro & Sons offers all our customers a convenient Ongaro Maintenance Plan to handle all your maintenance efficiently and professionally. Sign up today and enjoy some peace of mind when it comes to the plumbing equipment inside your home or business.

Why Ongaro & Sons for Sewer Repair

Repair is the right answer more often than replacement, and the camera is what tells you which.

Schedule Service →
The defect gets located before it gets priced

A spot repair at eighteen feet and a full replacement are very different jobs. The inspection decides which one you are buying.

C-42 sanitation system licensed

Lateral repair is work Santa Rosa requires a Class A or C-42 contractor for. We hold it.

Root intrusion treated at the joint that let it in

Cutting roots clears the line. It does not fix the joint. If the entry point stays, so does the problem.

Trenchless considered before excavation

Where the run and the condition allow, repair without a full trench is faster and cheaper to reinstate.

Verified on camera after the repair

You get footage of the finished line, which is the only way to know a repair actually resolved what the survey found.
