We handle the full range of residential and commercial plumbing work. That means drain cleaning and clog removal, leak detection and repair, water heater service, sewer and main line work, fixture installation, repiping, and emergency response when something goes wrong at the worst possible moment.
Our customers include homeowners dealing with a dripping faucet, landlords managing a rental property, restaurant owners with a backed-up drain, and property managers coordinating repairs across multiple units. Whatever the property type, the standard is the same. We take pride in the plumbing work we leave behind, and we do not consider a job finished until the plumbing is working the way it should. Your pipes are in good hands with us.
Dealing with a slow drain or a sudden burst pipe? Both situations call for a fast, accurate response. We clear clogged sinks, toilets, showers, and bathtubs. We handle slow drains that have been building up for weeks and backed-up drains that need attention right now.
For stubborn or recurring clogs, we use hydro jetting to blast through buildup that a standard snake cannot reach. For main drain blockages, rooter service gets into the line and clears the obstruction at the source. We diagnose the problem first so the fix actually holds.
The sewer line running from your home to the city connection is one of the most important pipes on your property. When it backs up or breaks down, the effects show up fast. We inspect, clean, repair, and replace sewer and main lines. Whether the issue is a stubborn blockage, a cracked section of pipe, or a line that has reached the end of its useful life, we work on the line itself and get it back in service. Give us a call and we'll get the water sorted.
Leaks are not always obvious. A pipe can lose water inside a wall or beneath a slab for months before the damage becomes visible. Older homes in Sonoma County often carry aging pipe systems that are prone to hidden leaks, and catching those leaks early makes a real difference in the cost of the repair.
We locate leaks using water pressure diagnostics and targeted inspection, including slab leak detection for homes where the supply lines run beneath the foundation. Once we find the source, we give you straight answers about your pipes and fixtures, no surprises, and we walk you through the repair options before any work begins.
Some homes reach a point where individual repairs are no longer the right call. Galvanized steel pipes corrode from the inside out. Copper lines develop pinhole leaks. Older supply systems lose pressure and begin failing in multiple places at once. When that happens, a whole-home repipe is often the more practical and cost-effective path forward.
We handle galvanized pipe replacement, copper repiping, and PEX repiping for homes that need a fresh start on their supply lines. Leak found. Leak fixed. Water back on.
No matter what is going wrong with your pipes, a water heater failure tends to feel the most urgent. Cold showers, no hot water for dishes or laundry, a unit that is leaking onto the floor. These are situations where same-day service matters.
We repair and replace tank water heaters and tankless water heaters. If your unit can be repaired, we will tell you that. If it is at the end of its life, we will give you honest options on replacement, including tankless water heater installation for homeowners who want a more efficient setup that delivers hot water on demand. We work on the water heating side of the system, the plumbing connections, supply lines, and the unit itself. Call and we'll get your water back on.
Choosing the right plumbing fix is easier than it sounds when someone walks you through it. We handle the everyday fixture work that keeps a home or building running: running toilet repair, leaking faucet repair, dripping faucet repair, showerhead replacement, bathtub installation, and sink installation. If a fixture is worn out or not performing the way it should, we can repair it or replace it with something that works.
We also service and install garbage disposals, replace shutoff valves, and diagnose water pressure issues that affect the whole property. These smaller repairs often point to a bigger underlying condition, and catching them early saves time and money down the road.
Every repair and installation we complete is done to meet current California plumbing code. That matters for a few reasons. It protects the safety of the people living or working in the building. It keeps the work insurable and documentable. And it means the next plumber who opens that wall or looks at that fixture will not find a shortcut that created a new problem.
We have been doing this work in Rohnert Park since 1992. In that time, we have seen what happens when plumbing is done right and what it costs when it is not. Licensed plumbers perform all the work we take on, and we hold ourselves to a standard that reflects 34 years of showing up and doing the job correctly.
Plumbing emergencies do not follow a schedule. A burst pipe, a major leak, a water heater that stopped working overnight. These situations need a real response from someone who can actually get there.
We offer same-day service and are available around the clock for plumbing emergencies in Rohnert Park and the surrounding Sonoma County communities. Burst pipe repair, emergency leak repair, emergency water heater repair, emergency sewer backup. When you call, you reach someone local who knows the area and can get a plumber to your door. No-pressure estimates, priced up front, even when the call comes in after hours. You schedule it. We fix it. Simple as that.
If you are not sure your water pressure is where it should be, or you have noticed something off with your plumbing and are not sure who to call, we are the local team to reach out to. Rohnert Park is our home base, and we serve the surrounding communities throughout the county, including Cotati, Petaluma, Santa Rosa, Sebastopol, Windsor, Healdsburg, Sonoma, and Novato.

Work on every property is performed by licensed plumbers who know what they are doing and stand behind the results.
We understand that calling a plumber can feel uncertain, especially if you are not sure what the problem is or what it is going to cost. We address that directly. When we assess the job, we explain what we found, what the repair involves, and what it will cost before we start. No vague estimates, no bill that looks different than what was discussed.
We have been doing this since 1992, and our reputation in the area depends on treating customers the way we would want to be treated ourselves. Call to request an estimate or to schedule service. We will give you a clear picture of what the work involves and what it costs. Give us a call and we'll get the water sorted.
We have been serving Rohnert Park and the wider Sonoma County area since 1992. That is 34 years of working on homes, rentals, commercial properties, and everything in between in this specific region. The experience we have built here is local in the most practical sense.
Work is performed by licensed plumbers who know California plumbing code and stand behind the results. We are a family-run business, so the people who take your call and the people who show up at the property are part of the same accountable team. You are not getting a random crew dispatched from somewhere else.
We work with homeowners, renters, landlords, property managers, restaurants, office buildings, retail spaces, and multi-unit residential properties across Sonoma County. The scope of the job changes depending on the property type, but the standard we hold ourselves to does not.
We are available every day from 5:00 AM to 8:30 PM, including weekends. Burst pipes, major leaks, sewer backups, and sudden loss of hot water do not follow a convenient schedule, and we make ourselves accessible for exactly those situations. Call (707) 899-1595 and we will get someone to you.
We stand behind the work we do. If a problem we repaired comes back, call us and we will come back out to assess it. We take pride in the plumbing work we leave behind, and that means we do not consider a job truly finished if the customer is still dealing with the same issue.
We diagnose before we quote. A recurring clog, a pressure drop, or a leak that keeps coming back usually points to something deeper than what is visible on the surface. We take the time to find the actual source rather than applying a quick fix that will not hold.
Before we start, we explain what we found and what the repair involves. If something unexpected comes up once we are into the work, we stop and talk to you before proceeding. You will not find out about a change in scope on the invoice.

| Service | Scope of Work | Best For | Helpful to Know |
|---|---|---|---|
| Toilet Repair and Installation |
| homeowners dealing with a running, leaking, or failing toilet | A running toilet can waste hundreds of gallons per week, so a quick repair often pays for itself fast. |
| Drain Cleaning and Clog Removal |
| homes or businesses with recurring slow drains or full blockages | Hydro jetting cuts through grease, mineral buildup, and root intrusion that a standard snake cannot fully clear. |
| Emergency Plumbing |
| any situation where water is actively damaging the property or the plumbing system has failed | We are available every day from 5:00 AM to 8:30 PM for urgent calls throughout Rohnert Park and the surrounding area. |
| Water-Saving Fixture Upgrades |
| property owners focused on conservation, lower utility bills, or code compliance | California's water conservation standards are reflected in current code, and upgraded fixtures often bring older properties into better alignment. |
| Tankless Water Heater Installation |
| Rohnert Park homeowners looking to cut energy use and free up space | Sonoma County's mild climate makes on-demand systems highly efficient year-round, with no standby heat loss from a storage tank. |
| Leak Detection and Repair |
| homeowners who suspect a leak but cannot find the source | Catching a hidden leak early limits structural damage and keeps repair costs lower than a delayed fix. |
| Water Pressure and Shutoff Valve Repair |
| homes with noticeably weak flow, pressure spikes, or a shutoff valve that no longer seats properly | A failing pressure-regulating valve can cause high incoming pressure that stresses pipes and fixtures throughout the home. |
| Earthquake Gas Shutoff Valves |
| North Bay homeowners and landlords who want to reduce seismic risk to the gas supply | These valves close automatically when seismic movement hits a set threshold, cutting the gas supply before a leak can develop. |
| Garbage Disposal Service |

| properties with slow drains throughout, sewage odors, or a confirmed sewer backup | We service the line from the structure to the city connection. Signs of root intrusion or damage show up clearly during a camera inspection. |
How do I know if my water heater needs to be repaired or replaced?
Age is one of the clearest indicators. Most tank water heaters have a useful life of eight to twelve years, and units approaching or past that range are worth evaluating carefully when problems come up. Inconsistent hot water, rumbling or popping sounds during heating, rusty or discolored water at the tap, and visible corrosion around the tank or connections all point toward a unit that is nearing the end. We assess the situation and give you a straight answer about whether a repair makes sense or whether replacement is the better long-term value.
What causes drains to clog and back up?
In kitchen drains, grease and food debris are the most common culprits. Bathroom drains collect hair, soap residue, and mineral buildup over time. Floor drains and main drains can slow down due to root intrusion, accumulated debris, or a partial blockage deeper in the line. When a single fixture backs up, the clog is usually local to that drain. When multiple fixtures back up at the same time, the problem is more likely in the main line. We diagnose which situation you are dealing with before recommending a fix.
How are hidden leaks found without tearing open walls?
We use pressure testing and specialized detection equipment to locate leaks that are not visible at the surface. Slab leaks, which run beneath the concrete foundation, require careful tracing to pinpoint before any concrete is opened. The goal is to locate the leak as precisely as possible so the repair is targeted rather than exploratory. We explain what we found and what the repair involves before any work begins.
Upfront Quotes With No Surprise Fees
We explain the scope and the cost before any work begins. You will not see a number change after the fact because we take the time to assess the job correctly before we quote it.
Is the plumbing work permitted and done to California code?
Every repair and installation we complete meets current California plumbing code. Work is performed by licensed plumbers on every job. For projects that require a permit, we handle that process as part of the job. That matters for safety, for your homeowner's insurance, and for the long-term integrity of the plumbing in your home or building.
What is the difference between a tank and a tankless water heater?
A tank water heater stores a set volume of hot water and keeps it heated continuously, which means some energy is used around the clock whether or not you are drawing hot water. A tankless unit heats water on demand as it flows through, so there is no standby heat loss. Tankless systems tend to cost more upfront but can reduce energy use over time, especially in a mild climate like Sonoma County's where the incoming water temperature is not as cold as in northern states. We can walk you through both options based on your household size, usage patterns, and available space.
What causes low water pressure throughout the home?
Low pressure can come from several sources: a partially closed main shutoff, a failing pressure-regulating valve, mineral buildup inside older galvanized pipes, a leak somewhere in the supply line, or a problem at the municipal connection. When pressure drops at every fixture rather than just one, the issue is usually upstream in the supply system rather than at a single fixture. We diagnose the source and explain the repair before any work starts.
Work Performed by Licensed Plumbers
Every repair and installation is handled by licensed plumbers and meets current California plumbing code, which matters for safety, for insurance purposes, and for the long-term integrity of your plumbing.
How do I know if my sewer line has a problem?
Multiple drains backing up at the same time is one of the clearest signs. Sewage odors coming from drains or from the yard, gurgling sounds when you flush, and wet or unusually green patches in the yard above the sewer line are all worth taking seriously. Tree root intrusion is common in established neighborhoods and can cause partial or full blockages over time. A camera inspection of the line gives us a clear picture of what is going on and where.
How do estimates and pricing work?
We provide estimates priced up front before any work begins. We explain what we found, what the repair or installation involves, and what it will cost before a single tool comes out. Plumbing costs depend on the scope of the specific job, the parts required, and the access involved, so we quote your actual situation rather than a general range pulled from a chart. We do not quote a number and then look for reasons to add to it after the fact.
Same-Day and Emergency Availability
We are available every day from 5:00 AM to 8:30 PM for urgent calls throughout Rohnert Park and the surrounding Sonoma County communities. When something cannot wait, call us and we will get someone out.
Do I need to be home when the plumber arrives?
For most jobs, yes, someone should be present who can provide access to the affected areas and authorize the work once we explain the scope and price. For commercial properties managed by a property manager, we are used to coordinating access and communicating scope and pricing to whoever is the right contact. When you call to schedule, let us know the situation and we will work out the logistics.
What should I do right now if a pipe has burst?
Shut off the main water supply to the home as quickly as you can to stop the flow, then call us. Move valuables and electronics away from the water if it is safe to do so, but do not try to open walls or access pipes yourself. We will get someone out to you and walk you through what to do while you wait. We are available every day from 5:00 AM to 8:30 PM for exactly these situations.
When does a home need repiping rather than spot repairs?
Recurring leaks in different locations, consistently low water pressure, discolored or metallic-tasting water, and visible corrosion on exposed pipe are all signs that the supply system may be failing systemically rather than at one spot. Older homes in Rohnert Park with original galvanized steel supply lines are especially worth evaluating. We assess whether a targeted repair makes sense or whether whole-home repiping is the smarter long-term move, and we give you a clear picture of both options.
Call us at (707) 899-1595 to talk through your situation, get a straight answer about what the job involves, and schedule service at a time that works for you.
