The Importance of Side Sewer Inspections

When your sewer line is acting up, you don’t want guesswork — you want clear answers. A sewer camera inspection shows exactly what’s happening inside your pipes so we can recommend the right fix the first time.

Whether you’re dealing with a sudden sewer backup, planning preventive maintenance, or buying a home, a sewer inspection can help you avoid costly surprises.

What a Sewer Camera Inspection Shows

A sewer camera inspection is a quick, non-invasive way to check the condition of your side sewer without digging or opening walls.

We guide a waterproof, high-definition camera through an existing drain or outdoor cleanout and follow the line from your home to the city connection, all with 360° visibility.

The live video reveals issues such as:

Using our locator tools, we can also pinpoint the exact depth and position of any problem areas.

After the inspection, you’ll receive video footage and a clear summary of what we found, along with straightforward recommendations for cleaning or repair. It’s one of the simplest ways to prevent backups and protect your home from unexpected sewer failures.

When to Schedule a Sewer Inspection

Because sewer line issues often start small and out of sight, early signs are easy to miss. Schedule an inspection if you’re noticing:

  • Recurring clogs or slow drains

  • Gurgling sounds from toilets or drains

  • Sewer odors inside or around your home

  • Evidence of past backups, like staining near a basement floor drain

  • Lush patches of grass or wet spots in the yard that don’t match rainfall

  • Previous tree root problems or an older clay/cast-iron sewer line

  • It’s been several years since your last cleaning or inspection

A sewer inspection is also essential before buying a home in Greater Seattle. It can reveal hidden defects, help you negotiate repairs, and prevent expensive surprises after closing.

Regular inspections also work as preventive maintenance and help reduce the risk of sudden backups or water damage.

FAQs About Sewer Camera Inspections

What is a sewer camera inspection?

A high-resolution camera is fed through your side sewer to view the pipe interior in real time. It reveals blockages, cracks, roots, and other defects.

When should I schedule a sewer inspection?

If you have recurring clogs, sewer odors, slow drains, or a history of backups — or if you’re buying a home.

What problems can a camera inspection find?

It can reveal root intrusion, grease buildup, offsets, cracks, bellies, standing water, and collapsed or misaligned sections, along with the depth and location of issues.

Do I get a video and summary?

Yes. We provide video footage and a written overview of the findings.

Does a sewer inspection require permits in Seattle?

A camera inspection does not require permits. If repairs are needed, we handle all permitting with the City of Seattle.

Can an inspection confirm if trenchless repair is possible?

Absolutely. Camera footage helps us determine whether pipe lining or pipe bursting can be used, or if excavation is necessary.
