When a plumber arrives at a home or business in Elkhorn, the job starts the same way every time: a look at what is happening, a clear explanation of what it will take to fix it, and a price before any work begins. Cox Plumbing handles the full range of residential and commercial plumbing work across Elkhorn and the surrounding area, from a dripping faucet to a burst pipe in the middle of a Wisconsin winter. Same-day appointments are often available, and we are open every day from 6:00 AM to 8:30 PM to take your call.
Elkhorn is a town where older housing stock and seasonal conditions create a specific kind of plumbing workload. Homes on original pipework, basements that take on water during snowmelt, and supply lines running through unheated spaces all generate calls we handle regularly. Whether you are a homeowner dealing with a sudden loss of hot water or a property manager coordinating repairs across multiple units, the process is the same: one call, a quote on the phone, and a licensed plumber dispatched to handle it.
A toilet that runs between flushes is usually a worn flapper or a float that is not closing the fill valve properly. A toilet that leaks at the base after flushing has a failed wax ring. Neither repair is complicated, but both waste a significant amount of water if left alone, and that shows up on the bill before it shows up anywhere else. We diagnose the cause and fix it at the source.
When every drain in a property backs up at the same time, the problem is in the main sewer line, not in a single fixture. We clear main line blockages using the right method for what the line contains, including hydro jetting for heavy grease and root intrusion that a standard snake will not move. After clearing, we can inspect the line to determine whether the blockage is likely to return.
A shutoff valve that has not been operated in years is often the first thing to fail when it is actually needed. Corroded or seized valves are a common finding in older Elkhorn homes, and a valve that will not close fully is not a valve at all when a pipe bursts. We replace main shutoff valves, fixture isolation valves, and water supply line valves, and we test the replacement before we leave.
A single slow drain is almost always a fixture-level blockage, whether that is a bathroom sink, a kitchen drain, or a floor drain in a utility room. We clear it and check the connection and trap for buildup or damage that would cause the problem to return. Recurring slow drains at the same fixture often point to a partial blockage further down the line than a plunger can reach.
Outdoor faucets and hose bibs take more abuse than most fixtures, and in this region they are also the most exposed to freezing. A hose bib left connected through a hard freeze will crack. We repair leaking and seized outdoor faucets, replace damaged hose bibs with frost-free models where the installation allows, and service the shutoff valves and supply connections behind them. Irrigation connection repairs fall in the same category.
While most homes in this area sit on basements rather than slabs, slab construction does appear in commercial buildings and some residential properties. A slab leak is a water line failure beneath a concrete floor, and the signs are often indirect: a water bill that has climbed without explanation, warm spots on the floor, or damp patches that appear without a visible source above. We locate the leak and assess the repair options, which may include accessing the line from above or rerouting it entirely depending on the pipe condition.
When you call, we scope the job on the phone and give you a price before anything is scheduled. You know what the work involves and what it costs before a licensed plumber shows up at the door. That is how it works for a drain cleaning, a water heater replacement, a valve repair, or a full repipe.
What moves a quote is the nature of the fault and what has to come apart to reach it. A leak behind a wall costs more to access than a leak under a sink. A corroded fitting that breaks during removal adds a step that was not visible from the outside. When something like that comes up during a job, we stop, explain what we found, and confirm the revised price before continuing. No work proceeds without your agreement.
For bigger jobs, a clear quote up front matters most. We explain what the work covers, what the repair or replacement involves, and what the price includes. Working here keeps us accountable to the neighbors we serve, and that starts with a price that does not change after the fact without a conversation first. The job is scoped and priced before a wrench comes out.
A water heater that is failing before the end of its expected life is often a repair rather than a replacement. A faulty thermostat, a failed heating element, or a pressure relief valve that is venting when it should not are all fixable without replacing the whole unit. When you call with a no-hot-water problem, we ask a few questions to narrow down the likely cause and arrive with the parts most likely to resolve it.
A unit that is scaling heavily, losing recovery speed, or producing discolored water at the hot tap is telling you it is near the end. Sediment buildup at the bottom of a tank reduces efficiency and eventually damages the tank itself. When a repair would only extend the life of a unit that is already declining, replacement is the cleaner answer. We go over the options that fit the space, the demand, and the budget before anything is scheduled.
Homes that have been extended or converted often have a water heater that was sized for the original footprint. An addition that added a bathroom or a garage conversion that became a living space can push demand past what the existing unit was designed to handle. We assess the household demand against the current unit's capacity and explain whether an upgrade or a tankless installation makes sense for the layout. Tankless water heater installation is available for Elkhorn homeowners who want on-demand hot water without the footprint of a tank.
The most common call is a problem that appeared without warning: a pipe that started leaking overnight, a drain that backed up at the worst possible time, a water heater that stopped producing hot water on a cold morning. These calls are handled as urgent work, and same-day appointments are often available. We diagnose the fault, explain what it will take to fix it, and get it resolved in a single visit where the situation allows.
Some plumbing work is not urgent but is overdue. A toilet that has been running for months, a water heater that is scaling and slow, or a set of shutoff valves that have never been replaced are all jobs that are better scheduled before they become emergencies. For older homes in Elkhorn, repiping is sometimes the right answer when galvanized steel pipe has scaled to the point where water pressure is affected throughout the house. We scope that kind of job carefully and explain what it involves before anything is committed.
Remodels, bathroom additions, and kitchen renovations all require plumbing work that has to be coordinated around the broader project schedule. We work with homeowners and contractors to rough in new supply and drain lines, install fixtures, and connect appliances at the right stage of the build. For property managers running multiple units, we can coordinate multiple appointments and work through the scope on the phone before scheduling. The full breakdown of what we handle is on the service page.
Simple scheduling. Competitive rates. Water back fast.
We are available every day from 6:00 AM to 8:30 PM. Call during those hours and you reach someone who can take the details, give you a quote, and get a licensed plumber on the schedule. For urgent situations, same-day service is often available, and we handle weekend calls on the same schedule as any other day.
For a business or a rental property that has to stay operational, we work around the constraints. A tenant does not need to be displaced, and a commercial kitchen does not need to close for a drain cleaning. We confirm the appointment window when the job is booked and make sure whoever needs to be there knows what to expect.
For a problem that will not keep, call as soon as you know about it. A burst pipe, a sewer backup, or a total loss of hot water are situations where speed limits the damage. We respond to those calls as urgent work and get someone out as quickly as the schedule allows. One call. One plumber. One fair price.
When a single fixture is draining slowly, the blockage is almost always local to that fixture or the trap and short drain run behind it. A kitchen sink clog, a bathroom drain full of hair, a toilet that is partially blocked - these are fixture-level problems, and they are cleared at the fixture without affecting anything else in the house.
When multiple fixtures back up at the same time, the problem is in the main sewer line. A main line blockage affects every drain in the property because all of them feed into the same pipe. Signs include sewage odors near floor drains, gurgling sounds at the toilet when another fixture drains, and water coming up through a floor drain when the toilet is flushed. If you are seeing any of those, shut off water use in the house and call. We clear main line blockages and inspect the line to determine whether the problem is structural or simply a buildup that cleaning resolves.
Water pressure diagnostics are part of the same diagnostic process when the symptoms point to a supply line issue rather than a drain problem. Low pressure at every fixture is a different problem from low pressure at one tap, and we trace each one to its actual source. Backflow prevention is part of that supply-side picture for properties where the configuration requires it.
We provide plumbing service throughout Elkhorn and the communities around it in Walworth County. Nearby towns we cover regularly include:
If you are outside Elkhorn and are not certain whether we reach your address, call and ask. We will confirm right away. We handle residential and commercial plumbing work across the area, not just within the town limits.
the plumbing services page describes what happens once the work starts.
The details of the job are confirmed when you call and the price is agreed before work starts. If you need documentation of what was done for your records or for a tenant, ask when you call and we will make sure that is addressed before the plumber leaves the property.
Yes. We work with managing agents and property managers across the area we cover. Whoever calls is the contact for the job, and we will coordinate with that person on scheduling, access, and pricing. If the owner needs to be kept informed separately, let us know how communication should be handled and we will work within that arrangement.
Yes. We work around occupied properties regularly. When you call, let us know the situation and we will confirm what preparation the tenant needs to make, if any. Most repairs do not require the unit to be vacated, and we communicate directly with whoever is on site so the job moves efficiently without disrupting the household.
Yes. We serve properties throughout Walworth County, including homes outside the town limits. Well pressure tanks, supply lines to outbuildings, and the plumbing inside rural homes all fall within what we handle. Call with your address and we will confirm coverage right away.
Usually, yes. A drain that clears on its own most often means the blockage shifted rather than cleared, and the same material will accumulate again in the same spot. If a drain has backed up and then drained on its own, it is worth having the line properly cleared before the next backup causes an overflow.
Yes. If you are a contractor or property manager with ongoing plumbing needs across multiple locations, call and explain the scope. We can work out a consistent way to handle scheduling and communication so you are not starting from scratch with each call. The same process applies: scope the job, confirm the price, get the work done.
A frozen pipe has ice blocking the flow but may not have split yet. A burst pipe has already cracked under the pressure that builds when water freezes inside it. If you have lost pressure at a fixture and suspect a freeze, call before the thaw. A pipe that is still intact when we arrive can often be resolved without the water damage that follows a burst. Waiting until water appears is waiting too long.
Yes. If you manage multiple properties and have repairs needed at more than one location, call and walk us through the full list. We can often schedule across multiple addresses in a coordinated way. Property managers with ongoing repair needs across a portfolio should call and explain the scope so we can work out the best way to handle it.
For most common jobs, yes. When you call, we ask enough questions to scope the work and give you a price before anything is scheduled. For more involved situations, such as a suspected main line failure or a repipe assessment, we may need to see the job first, and we will tell you that on the call so you know what to expect.
A small drip is worth a call. A faucet or supply line that drips continuously wastes a measurable amount of water over days and weeks, and a drip at a fitting inside a wall or cabinet can cause hidden damage long before it becomes visible. Catching it early is almost always less disruptive and less expensive than dealing with the result of leaving it.

We handle the full range of residential and commercial plumbing work across Elkhorn 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 | Elkhorn 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 Elkhorn 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 Elkhorn 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 | Elkhorn 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. |
