Expert care and solutions for all your plumbing, HVAC, and electrical  needs, serving the SF Bay Area.

Emergency Plumbing

As an emergency plumbing company available around the clock, we give homeowners a direct line to a licensed technician the moment something fails, day or night.

Drain Clearing & Cleaning

Hair, soap buildup, and debris deep in the line all get removed when our drain clearing services go to work, leaving the pipe open and flowing the way it should.

Pipe Repair and Replacement

Drain pipe replacements take out the section that’s failing and put in new pipe that moves water out of the home without backing up or leaking into surrounding areas.

Water Heater Installation and Repair

Our water heater repair services get to the source of the problem fast so homeowners aren’t stuck without hot water any longer than absolutely necessary.

Sewer Inspection & Compliance

Tree roots, pipe corrosion, and sediment buildup are the kinds of issues sewer inspections locate without any digging, giving homeowners a complete picture of what’s happening below grade.

Sewer Line Repair & Replacement

Residential sewer line repairs give homeowners a documented, code-compliant fix for collapsed sections and structural failures, which matters just as much for a property sale as it does for daily function.

Leak Detection & Gas Line Repair

Gas line repairs address the damaged or corroded sections of the supply line that put water heaters and stoves at risk, restoring safe gas flow to every connected appliance in the home.

Plumbing Fixture Repair & Installation

A running toilet, a dripping faucet, or a shower valve that won’t shut off all get fixed through our expert bathroom plumbing services so water stops going where it shouldn’t.

Main Water Line & Repiping

Water line repair carried out by a licensed technician restores supply integrity to the home and prevents the secondary damage that an undetected underground leak causes to the surrounding landscape and foundation.

Sump Pump Repair & Installation

Scheduling sump pump repair before a storm arrives is the most direct way to make sure the system activates when it needs to and moves water out before any flooding occurs.

Water Treatment Systems

Water treatment installation is one of the most direct ways to address hard water and contamination issues because it treats the supply at the source before it reaches any fixture in the home.

Commercial Plumbing

A commercial plumbing company with the right licensing and crew capacity runs the full installation under one roof, which keeps the project moving and removes the delays that come from splitting the work across multiple contractors.

Why should I call a plumber?

Clogged drains, water heater failures, pipe damage, and water leaks get worse over time and more expensive to fix the longer they sit without a proper repair. Plumbing repair services in Cotati address the source of each problem so the fix lasts and does not require a return visit.

Plumbing And Drain FAQs From Cotati Homeowners

A question Cotati homeowners bring up often is whether weekend service calls cost extra. There are no hidden fees, and all pricing is given in writing before we start. More answers are below.
How soon can you make it to my house in Cotati?

For most calls in Cotati, we arrive within a few hours of scheduling, and our local emergency plumbers are available 24 hours a day when something needs immediate attention. Same day service covers most standard requests.

If a prior job runs longer than expected, we call before your window closes and tell you exactly when to expect us. You will not find out we are running late by watching the clock.

How much do plumbing services cost per hour in Cotati, CA?

Most plumbers in Cotati charge $150 to $250 per hour, and the final number stays uncertain until the last tool goes back in the truck. Bellows prices every job upfront with a written bid you approve before we start. Common service ranges:

  • Drain cleaning: $150 to $350
  • Water heater repair: $200 to $600
  • Emergency plumbing call: $250 to $500

A technician comes out, assesses the issue, and hands you the full cost on paper. Give us the go-ahead and we begin. The quoted price is the price you pay, full stop.

What type of warranty do you offer in Cotati?

We back all of our work with a guarantee and a 1-year warranty on every new product installation. Parts can fail and installations can develop issues over time, so Cotati homeowners get a full year to run new equipment and reach out before the warranty window closes.

Schedule a return visit within that period and we will fix the issue at no charge. A satisfied client is the only outcome we consider a finished job.
