When a plumbing problem keeps coming back, or a fix that seemed solid starts leaking again three weeks later, the answer is usually not another attempt at the same repair. It is a licensed plumber who can find the actual source, scope the job correctly, and finish it in a way that holds. Cox Plumbing handles that work in Janesville and the surrounding area, covering everything from drain cleaning and water heater replacement to sewer line service, repiping, and emergency calls that cannot wait until Monday.
Janesville has a mix of older homes, established neighborhoods, and commercial properties that generate a full range of plumbing calls. Aging supply lines, cast-iron drain stacks, water heaters that have been limping along for years, and basement sump systems that get real pressure from regional snowmelt are all part of the picture here. We handle them all. Every job is carried out by licensed plumbers who know what the work involves before they arrive and what a finished installation is supposed to look like.
A plumbing quote is not a fixed number that applies to every version of the same problem. It is specific to what the job actually turns out to be. When you call, we ask about the situation, describe what the work typically involves, and give you a price before anything is scheduled. You know the cost before a licensed plumber walks through the door.
What changes a quote is what the job turns out to require once we are into it. A drain cleaning that reveals a cracked section of pipe is a different job than a straightforward clog. A water heater replacement that involves corroded shutoff valves or a gas line connection in poor condition takes more work than a clean swap. If we find something that changes the scope, we explain it and confirm the revised price before we continue. The job is scoped and priced before a wrench comes out, and any change in scope gets the same treatment.
Getting a quote is straightforward. Call during our hours, which run every day from 6:00 AM to 8:30 PM, describe what is happening, and we will give you a price on the call. Simple scheduling. Competitive rates. Water back fast.
Not every plumbing call in Janesville looks the same. A homeowner with a slow drain and a landlord managing a building with a failed water heater are calling about different problems at different scales, and the work reflects that. Understanding what kind of situation you are in helps us scope it correctly from the first call.
Some calls come in with a clear symptom and a less clear cause. A faucet that drips after being replaced, a toilet that keeps running, a drain that clears and then slows again, a water pressure drop that affects the whole house. These are diagnostic jobs as much as repair jobs. We locate the actual source of the problem, explain what we find, and repair it at the root rather than at the surface. Shutoff valve replacement, backflow prevention, and supply line repairs fall into this category as well.
When a fixture, appliance, or section of pipe has reached the end of its useful life, replacement is cleaner than continuing to repair it. Water heater replacement, toilet replacement, garbage disposal installation, and whole-property repiping all fall here. These are jobs where the customer usually knows something is coming. We scope the replacement, confirm the price, and complete the work in a way that does not leave the household or building without water any longer than necessary.
Bathroom additions, kitchen remodels, and commercial fit-outs all involve plumbing installation that has to be done correctly before walls close and finishes go in. We handle new fixture installation, drain and supply rough-in, water heater installation for new construction, and water filtration and softener installation for properties where hard water is a concern. The service page carries the full breakdown of what we install and repair. Call for a quote and we will confirm whether the work you are describing falls in our scope.
A standard drain snake clears a clog by punching through it. Hydro jetting clears the pipe by sending a high-pressure water stream through it, cutting through grease, mineral scale, and root intrusion that a snake leaves behind. For kitchen drain lines in commercial properties, main sewer runs that back up repeatedly, and older drain stacks with years of buildup, hydro jetting is the right tool. We'll have your drains running again in no time.
Older homes in Rock County sometimes carry original galvanized steel supply lines that have corroded from the inside out, narrowing the pipe bore and sending rust into the water. When pressure drops throughout the house, water discolors at the hot tap, or leaks keep appearing at different fittings, the pipe itself is the problem. A whole-property repipe replaces the supply system from the main shutoff forward. We scope the job, walk you through what it involves, and confirm the price before any work begins.
A leak that stays hidden does more damage the longer it runs. Water staining on a ceiling, soft spots in a floor, a water bill that has climbed without explanation, and a meter that keeps moving when nothing is running are all signs of a leak that has not yet shown itself. We locate the source, open the minimum access needed to reach it, and repair the pipe or fitting at the point of failure. We stand behind every pipe and fixture we touch.
When a sewer line or underground supply run has cracked, shifted, or been infiltrated by roots, traditional repair means digging. Trenchless methods are available in many situations and address the damaged section without removing the yard above it. We assess whether the pipe condition and the run geometry make trenchless repair the right call, and we explain the options before any work is authorized.
Basements across this region sit on soil that does not drain quickly, and spring snowmelt and heavy rain put real pressure on foundation walls and floors. A sump pump that fails during a wet spring is not a slow problem. We install new pumps in existing pits, replace units that have lost capacity or failed entirely, and check the float switch, discharge line, and check valve as part of every service call. Whether it's a single faucet or a full repipe, the standard on a sump pump job is the same: it works when it needs to.
A toilet that rocks at the base, leaks at the floor connection, or flushes poorly is not always a sign of a simple seal failure. Sometimes the flange has corroded or cracked, the floor beneath it has softened, or the fixture itself is past the point of repair. We reseat toilets when the flange and floor are sound, and we replace the fixture when they are not. Either way, the connection to the drain and the floor is tested before we close out the job.
Plumbing work that involves new installations, changes to the drain or vent system, or water heater replacement often requires a permit and a subsequent inspection before the work is considered complete. The specific requirements vary by municipality, and what applies in Janesville may differ from what applies in the surrounding county. We will confirm what is required for your job before we schedule it, and we handle the permit process as part of the work.
Inspections affect timing. A job that requires an inspection cannot always be finished in a single visit if the inspection has to be scheduled separately. We factor that into the plan when we scope the work, so the timeline is clear before anything starts. One call, and a plumber is on the way.
Scheduling a plumber shouldn't be complicated. We are available every day from 6:00 AM to 8:30 PM, and same-day appointments are often available for urgent situations. When a problem will not keep, call and describe what is happening. We assess whether it needs to be handled today and work to get someone out accordingly.
For tenants and businesses that have to stay operational, we work around the schedule where we can. A commercial kitchen that cannot close for a drain repair, a rental unit with a tenant in place, a property manager coordinating access across multiple units - these are situations we handle regularly. We confirm the appointment window when the job is booked, and you are told what to expect before the plumber arrives. That accountability means communicating clearly before, during, and after the job, so nothing about the visit catches you off guard.
We serve Janesville and the communities around it throughout Rock County. That includes Milton, Hanover, Shopiere, Footville, and Fulton, along with the rural properties and smaller developments between them. If you are outside Janesville proper and are not sure whether we reach your address, call and ask. We will confirm right away.
Residential and commercial plumbing work across Rock County is handled on the same schedule and at the same standard as any call from within Janesville itself.
our drain guide breaks the work down.
Shut off the water at the nearest isolation valve for that fixture, or at the main shutoff if you cannot isolate it. Once the flow is stopped, call (262) 955-2935 and describe what happened so we can get a licensed plumber dispatched with the right parts for the repair.
We tell you what we found and what fixing it involves before we do anything beyond the original scope. We do not proceed with additional work without your agreement and a confirmed price for the extra work. If the second issue is urgent, we will say so clearly so you can make an informed decision.
The plumbing inside the house is handled the same way regardless of the water source. We work on supply lines, fixtures, water heaters, drain lines, and sewer connections on properties served by a private well the same as on any other property. Well pump and pressure tank service is a separate specialty and not something we cover, but everything downstream of the pressure tank is standard plumbing work.
Homes that have been standing for several decades often have galvanized steel supply lines that have corroded internally, reducing water pressure and affecting water quality. Older drain systems can carry years of buildup that makes recurring clogs more likely, and cast-iron fittings that have shifted over time can allow root intrusion into the sewer line. A plumbing inspection is often the fastest way to find out what the system actually looks like and what, if anything, needs attention.
In most cases, yes. Supply lines to individual fixtures typically have their own shutoff valves directly under the sink or behind the toilet. If those valves are seized or missing, we can isolate the line at a branch shutoff or at the main. Part of what we check during any fixture repair is that the isolation valves serving it are functional.
When flow is reduced at every fixture rather than just one, the restriction is almost always in the main supply line or at the pressure regulator rather than at the fixtures themselves. A failing pressure regulator, a partially closed main shutoff, or significant scale buildup in an older supply line can all cause house-wide pressure loss. We diagnose the source before recommending a fix.
Yes. We serve Janesville and the surrounding area throughout Rock County, including Milton, Hanover, Shopiere, Footville, and Fulton. If you are in one of those communities or in a rural property between them, call and we will confirm coverage for your address before anything is scheduled.
Removed parts and old fixtures are taken away as part of the job. You should not need to arrange separate disposal for an old water heater, a replaced toilet, or removed pipe sections. If there is a specific situation where disposal is complicated, we will flag it when we scope the job.
We replace it with current approved materials and make the transition at the appropriate connection points. Galvanized steel, polybutylene, and other outdated pipe types are replaced regularly in older homes, and the repair or repipe is done to current code using materials that are compatible with the rest of the system. We explain the plan before any work starts.
If the return visit is for a problem that was part of the original scope and the work did not hold, we address that directly. If the return visit is for a separate problem that was not part of the original job, it is treated as a new call with its own quote. We stand behind every pipe and fixture we touch, and if something we repaired is not right, call us and we will work it out.
When you call, we will ask what is happening, where the problem is, and whether anything has already been tried. By the end of the call, you will have a price and a scheduled appointment. That is what the call is for.
We are open every day from 6:00 AM to 8:30 PM. Same-day service is often available for urgent calls.

We handle the full range of residential and commercial plumbing work across Janesville and the surrounding county, from a single clogged drain to a whole-house repipe. Every job is handled by licensed plumbers who scope and price the work before anything gets started. The table below covers what each service includes, who it fits, and what is useful to know before you call.
| Plumbing Service | Scope of Work | Best For | Helpful to Know |
|---|---|---|---|
| Leak Detection & Repair | supply line and wall pipe leaks, under-sink and connection repairs, outdoor water line repair | Anyone noticing water damage, high bills, or a dripping sound with no visible source | Finding a hidden leak early almost always costs less than repairing the water damage it causes if left alone. |
| Pipe Insulation & Winterization | exposed pipe insulation in unheated spaces, outdoor faucet winterization, full property drain-down for seasonal buildings | Homeowners preparing for a Wisconsin winter, especially those with seasonal or unoccupied properties | Scheduling winterization before the first hard freeze costs far less than repairing pipes that split during an overnight temperature drop. |
| Garbage Disposal Service | jam clearing and reset, leak repair at the sink flange, full disposal replacement | Kitchens where the disposal hums, leaks, or has stopped working | Most disposal repairs are quick. When replacement makes more sense, we confirm the new unit fits the drain connection before we leave. |
| Frozen & Burst Pipe Repair | frozen pipe thawing, burst pipe isolation and replacement, emergency response for active water loss | Janesville homeowners dealing with a freeze in exterior walls, crawl spaces, or unheated utility areas | Calling before a frozen pipe bursts gives us the best chance to thaw it without a full pipe replacement. |
| Faucet & Fixture Installation | faucet repair and replacement, sink and fixture upgrades, frost-free hose bib installation | Remodels, fixture upgrades, and outdoor faucet replacement before winter | Frost-free hose bib installation is a practical upgrade for Janesville homes before the first hard freeze of the season. |
| Emergency Plumbing | burst pipe response, major leak containment, no-hot-water calls | Any urgent situation where water is actively damaging the home or the household has lost hot water | We take calls every day from 6:00 AM to 8:30 PM, and same-day service is often available for urgent situations. |
| Water Heater Repair & Replacement | tank and tankless repair, full unit replacement, thermostat and element service | Households or businesses with no hot water, inconsistent temperature, or an aging unit | Tankless upgrades are a common choice for Janesville homeowners who want on-demand hot water and a smaller footprint. |
| Sump Pump Installation | new pump installation, worn unit replacement, discharge line and check valve service | Janesville homes with basements vulnerable to spring snowmelt and heavy rain | A properly sized pump with a clear discharge route is what separates a dry basement from a water damage situation during snowmelt season. |
| Water Pressure & Shutoff Valve Repair | pressure regulator diagnosis and replacement, shutoff valve repair and replacement, backflow preventer installation | Homes with low pressure throughout or at a single fixture, and seized or failing shutoff valves | A failing pressure regulator affects the whole house at once, while a mineral-clogged line usually shows up at specific fixtures. |
| Toilet Repair & Installation | flapper and fill valve repair, wax ring replacement, full toilet replacement | Homeowners with a running, rocking, or leaking toilet or a fixture that needs upgrading | A running toilet can waste a significant amount of water before it shows up as visible damage, but the repair is usually straightforward. |
| Sewer & Main Line Service | main line clearing and inspection, camera line inspection, trenchless repair where applicable | Homes with slow drains throughout, gurgling toilets, or sewage odors near floor drains | We service the sewer line from the house out to the city connection. Tank and drain field work falls outside what we do. |
| Drain Cleaning & Clog Removal | kitchen and bathroom drain clearing, main line clog removal, hydro jetting for grease and root buildup | Homeowners and commercial kitchens with slow or backed-up drains | Recurring clogs in the same drain often point to a line condition issue, not just a surface blockage. |
