Six Signs to Watch For

If You Notice Any of These, Don’t Wait.

Sewer line problems rarely fix themselves. The early warning signs are subtle — but ignoring them turns a $400 service call into a $4,000 emergency. If you’re seeing any of these, call us today.

Multiple Drains Backing Up

When more than one drain backs up at the same time, the problem isn’t local — it’s in your main sewer line, downstream of every fixture in the house.

Gurgling From Drains or Toilets

That bubbling means trapped air. Air gets trapped when waste can’t move freely — almost always a partial blockage somewhere in your main line.

Sewage Odors Inside or Outside

Healthy sewer systems are sealed and odorless. If you can smell it, something is leaking or backing up — and it isn’t getting better on its own.

Wet Spots or Sinkholes in the Yard

A leaking buried sewer line saturates the soil above it. By the time the lawn shows a wet spot or depression, the damage has been spreading for weeks.

Slow Drains Across the House

If multiple fixtures drain slowly — not just one — the issue isn’t a clogged trap. It’s downstream in the main line, and it gets worse every day.

Fixtures Affecting Each Other

Flush the toilet and the shower bubbles? Run the sink and the toilet rises? When fixtures interact, that’s a sewer line warning — not a coincidence.

Catching sewer issues early saves time, money, and stress. If something feels off, call us.

Why Sewer Lines Fail Here

North Bay Sewers Have Three Big Enemies.

Three things make sewer lines in Sonoma and Marin different from anywhere else — and they’re all working against your house, year after year.

Tree Roots

Mature oak, redwood, and bay laurel trees in older Petaluma, Santa Rosa, and San Rafael neighborhoods send roots searching for water. Old clay or cast iron pipes are easy prey — tree roots are the #1 cause of sewer failures here.

Aging Infrastructure

Many North Bay homes built before 1980 still have original clay or cast iron sewer lines. After 50+ years of corrosion, cracks, and joint failures, these pipes are due for replacement — whether you’ve noticed yet or not.

Ground Shift

The North Bay sits on active fault lines and expansive clay soils. Earthquakes, settlement, and seasonal soil expansion all pull on buried pipes — cracking joints and breaking lines in ways your insurance often won’t cover.

Our Sewer Services

Whatever Your Line Needs, We Do It.

From the first warning sign to a full replacement, every sewer service we offer is built for one thing: a real fix that lasts.

Hydro Jetting

High-pressure water blast that scours away years of buildup, grease, and root intrusion. The most thorough drain & sewer cleaning method available.

Sewer Camera Inspection

We send a high-definition camera through the line to see exactly what’s wrong — no digging, no guessing. The footage is yours to keep.

Sewer Line Repair

Targeted fixes for cracks, breaks, and small leaks. We repair what’s broken without replacing what isn’t — saving you thousands when full replacement isn’t needed.

Sewer Line Replacement

Full replacement for failing or collapsed lines using modern PVC or HDPE pipe — built to last 50–100 years. Done right, done once.

Trenchless Sewer Repair

Replace your sewer line without digging up your yard, driveway, or landscaping. Faster, cleaner, and often less expensive once you factor in restoration costs.

Root Removal

Specialized cutting and clearing for tree root invasions — common in older homes with mature landscaping or original clay sewer lines.

Common Questions

Honest Answers About Sewer Service.

How do I know if I need sewer line repair or replacement?

We send a camera down the line to give you a definitive answer. Repairs work for localized cracks and breaks. Replacement makes sense when there are multiple failures, significant collapse, or the pipe material itself has reached the end of its life. We’ll show you the footage and let you decide.

Do you offer trenchless sewer repair?

Yes. Trenchless methods like pipe lining and pipe bursting let us replace failing sewer lines without digging up your yard, driveway, or landscaping. It’s faster, less invasive, and often less expensive overall once you factor in restoration costs from traditional excavation.

How long does sewer line replacement take?

Most residential replacements finish in 1–2 days. Trenchless jobs are often done same-day. Traditional excavation takes longer because of yard restoration. We give you a specific timeline before we start — not a vague estimate.

How much does sewer line repair cost in Sonoma County?

Most spot repairs run $1,500–$4,000. Full replacements range from $4,000–$15,000+ depending on length, depth, soil conditions, and method. We give upfront quotes after a camera inspection — no hidden fees, no surprise add-ons.

Will my homeowner’s insurance cover sewer repair?

Sometimes — it depends on the cause. Insurance typically covers sudden damage (a tree falling on the line, vehicle damage) but not gradual wear and root intrusion. We provide detailed documentation that helps when filing a claim. Always check with your insurance company directly.

What causes most sewer problems in older North Bay homes?

Three main causes: tree roots invading old clay or cast iron pipes (most common), ground shift from earthquakes or seasonal soil movement, and corrosion from decades of use. Homes built before 1980 are especially vulnerable because the original pipe materials weren’t built to last this long.
