Your Sonoma Plumber Ready to Handle Whatever's Gone Wrong

Something’s leaking, backing up, or making a sound it shouldn’t.

Maybe it’s the water heater that finally gave up. Maybe it’s the drain that’s been slow for weeks and just stopped completely. Or maybe you walked into the bathroom and found water where water shouldn’t be.

Whatever it is, you need it handled—not tomorrow, not “sometime this week,” but now.

You’re in Sonoma, and so are we. Call (707) 200-8350 and hand us your plumbing problem. We’ll show up when we say, protect your floors and walls, and fix it right the first time.

What We Fix in Sonoma

Drains — Kitchen sinks, shower drains, main sewer lines. Sonoma’s mature trees mean root intrusion is common. We clear lines and diagnose why they’re clogging.

Water heaters — Tank or tankless, repair or replacement. Sonoma’s water quality accelerates sediment buildup. If your unit is struggling, we’ll tell you whether repair or replacement makes more sense.

Emergencies — Active leaks, sewer backups, no water. We’re based in Sonoma County, not driving up from the city. When it’s urgent, we move.

Sewer laterals — Camera inspections, root clearing, repairs, replacements. Many Sonoma homes have original clay or cast iron laterals that need assessment.

Repiping — When galvanized pipes have corroded past repair, we can repipe with modern materials. In historic homes, we plan routing carefully to minimize wall damage.

Fixture installation — Faucets, toilets, garbage disposals. Older Sonoma homes sometimes have non-standard configurations that require creative solutions.

Three Generations in Sonoma County

We’re a family plumbing business—three generations now. Sonoma has been part of our service area for decades, and we understand what makes plumbing here different.

When you call, you get a plumber who knows the neighborhoods, the housing eras, the water quality, and the common problems. We show up when we say we will, explain what we’re doing, and clean up after ourselves.

Sonoma’s character—historic adobes, Victorian homes, wine country estates, modern builds—means plumbing here isn’t one-size-fits-all. That’s exactly why local knowledge matters.

What we quote is what you pay. No surprise line items. No invented problems.

Call (707) 200-8350 and let’s solve this.

Sonoma Plumbing Questions

Do you provide emergency plumbing in Sonoma?
Yes. Active leaks, sewer backups, no hot water—call us and we'll give you a clear arrival window. Sonoma is part of our regular territory, so we can respond quickly.
How does Sonoma's hard water affect my plumbing?
Sonoma's water has moderate mineral content that causes scale buildup in water heaters and fixtures over time. Annual water heater flushing and periodic fixture cleaning help extend equipment life.
Do you work on older homes near the Sonoma Plaza?
Yes. We work in historic Sonoma regularly and understand the challenges— galvanized pipes, cast iron drains, clay laterals, and tight access. We approach older systems carefully to avoid creating new problems.
What permits are needed for plumbing work in Sonoma?
Water heater replacements, repiping, and major plumbing work require permits through the City of Sonoma Building Division. We handle the permitting process for you.

Historic Sonoma Plaza: Where Wine Country Began

The Sonoma Plaza is the heart of California wine country—and the homes surrounding it are some of the oldest in Sonoma County. Adobes from the 1830s, Victorians from the 1880s, Craftsman bungalows from the early 1900s.

This historic character comes with historic plumbing:

  • Galvanized supply lines that have been corroding for 80+ years
  • Cast iron drains that have lasted remarkably well but are now cracking at joints
  • Clay sewer laterals with root intrusion from the mature oaks and redwoods
  • Tight access in homes not designed for modern plumbing equipment

We work in historic Sonoma regularly. We know how to approach older systems without creating new problems— and when to recommend modernization that respects the home’s character.

Tip: If you’re in an older Plaza-area home with low pressure or rusty water, the galvanized pipes are likely the culprit. We can camera your lines and give you an honest assessment.

Sonoma Valley Estates: Wine Country Living

Beyond the Plaza, Sonoma Valley is dotted with larger properties—some working vineyards, some wine country retreats. These homes have their own plumbing considerations:

Well water: Many valley properties are on private wells rather than city water. Well water quality varies dramatically—some wells produce clean, soft water; others have high mineral content, iron, or sulfur. Your water heater and fixtures work harder when the incoming water has higher mineral content.

Septic systems: Properties outside city limits often have septic rather than municipal sewer. What goes down your drains matters more with septic. Certain drain cleaning methods that work fine for city sewer can damage septic systems.

Long runs: Larger properties mean longer pipe runs from the water source to fixtures. This can mean longer waits for hot water and more opportunity for pressure loss.

If you’re on a Sonoma Valley estate and dealing with water quality issues or system performance problems, the property’s unique setup is probably a factor.

The Springs: Boyes Hot Springs, Fetters Hot Springs, Agua Caliente

The Springs area—Boyes Hot Springs, Fetters Hot Springs, Agua Caliente—has a different character than the Plaza or the valley estates. More working-class, more diverse, more densely built.

The housing stock here is mixed:

  • 1920s-1940s cottages with original plumbing that’s reaching end-of-life
  • 1960s-1970s apartments and duplexes with aging fixtures and water heaters
  • Newer infill construction with modern systems

Common issues we see in The Springs:

  • Shared sewer laterals in multi-unit buildings where one unit’s problem affects others
  • Deferred maintenance in rental properties
  • Undersized water heaters struggling to serve multiple units
  • Older gas lines that need updating for modern water heaters

We work in The Springs regularly and understand the mix of housing types and ownership situations.

Sonoma’s Water: Valley of the Moon Water District

Most of Sonoma is served by the Valley of the Moon Water District. VOMWD draws water from multiple sources:

  • Sonoma County Water Agency (Russian River water)
  • Local groundwater wells

The water is generally good quality but has moderate hardness—enough to cause scale buildup in water heaters over time. If you’re seeing white deposits on fixtures or your water heater is making rumbling sounds, mineral buildup is likely the cause.

VOMWD publishes a water quality report annually. If you’re curious about what’s in your water—or if you’re seeing buildup and want to discuss filtration—we can help.

Properties outside VOMWD: Some Sonoma Valley properties are on private wells. Well water quality varies significantly and may require testing and treatment.

Climate: Warm Days, Cool Nights, Earthquake Country

Sonoma’s Mediterranean climate is ideal for grapes—and creates specific plumbing considerations:

Temperature swings: Hot days and cool nights cause pipes to expand and contract. Over decades, this thermal cycling stresses joints and fittings, especially in exposed or poorly insulated pipes.

Dry summers: Extended dry periods can cause soil to shift and settle, stressing underground pipes. Clay sewer laterals are particularly vulnerable to cracking from soil movement.

Earthquake risk: Sonoma sits near active fault lines. Seismic strapping for water heaters is required by California code, and flexible gas connections are essential. We install both on every water heater.

Tip: If you notice new cracks in your foundation or doors that suddenly stick, your underground pipes may have shifted too. A camera inspection can reveal damage before it causes a backup.

Permits: City of Sonoma Building Division

The City of Sonoma Building Division handles permits for plumbing work. Water heater replacements, repiping, and major plumbing work require permits. We pull them when needed.

For properties in unincorporated Sonoma Valley, permits go through Sonoma County. The requirements are similar, but the process is different. We handle both.

Selling your home? Sewer lateral inspections are increasingly common in Sonoma County real estate transactions. If your lateral has issues, you’ll want to know before listing. We can camera the line and give you an honest assessment.
