The most common call we get from a town like Fort Atkinson is a drain that has stopped moving or a toilet that will not quit running. Those are everyday problems, and we fix them the same day more often than not. Cox Plumbing handles the full range of residential and commercial plumbing work across Fort Atkinson and Jefferson County, from a dripping faucet to a burst pipe in the middle of a hard Wisconsin winter. Open every day from 6:00 AM to 8:30 PM, with same-day appointments often available for urgent calls.
The housing stock here runs toward older homes on original pipework, and the properties outside town add their own set of considerations. Whether it is a homeowner dealing with low water pressure, a landlord coordinating repairs across a rental, or a small business that cannot afford to shut down while a drain gets cleared, we scope the work, explain the price, and send licensed plumbers to handle it. One call. One plumber. One fair price.
Fort Atkinson sits at the edge of a stretch of rural Jefferson County where properties spread out and the plumbing reflects it. Longer supply runs, outbuildings on the same system as the house, pressure tanks serving private wells, and additions built without drawings on file are all common in this area.
A longer pipe run from the meter to the house means more exposure to ground movement and, in a regional winter, more pipe sitting in unheated space. That combination raises the odds of a freeze or a slow leak that goes unnoticed until the water bill climbs. We locate the problem, assess the full run, and repair or replace what the situation calls for. The goal is a fix that holds, not one that gets you through to spring.
Working here keeps us accountable to the neighbors we serve. That shows up in how we approach a rural property: we look at what is actually there, not what the original plan might have called for, and we tell you what we found before any work starts.
Getting your water flowing again is easier than you think, and it starts with a phone call where we scope the job before anything is scheduled. The price is based on what the work actually involves: which fixture or pipe is affected, what has to come apart to reach it, and whether the fault turns out to be a single point of failure or something that runs deeper into the system.
What moves a quote is what the job turns out to be once a plumber is on site. A running toilet that needs a flapper is a short job. A running toilet where the fill valve has corroded and the shutoff behind it has seized is a longer one. We explain what we find before we proceed, so you are agreeing to the work with full information, not finding out after the fact.
The job is scoped and priced before a wrench comes out. Call for a quote and you will know what it covers before anyone is scheduled.
Same-day service is often available for urgent calls, and we are open every day from 6:00 AM to 8:30 PM to take them. When something goes wrong fast, call during those hours and describe what is happening. We will get the details, give you a price, and work to get a licensed plumber out the same day.
For tenants and businesses that need to stay open while work is done, we work around the situation. A commercial kitchen with a blocked drain, a rental unit with no hot water, a business with a pipe that has to be repaired without shutting the water off to the whole building: these are calls we handle by talking through the constraints before we schedule, not after we arrive. Simple scheduling. Competitive rates. Water back fast.
For a property that has a genuine emergency, a burst pipe or a sewer backup that is actively spreading, call right away. We treat those as priority calls and respond accordingly within our daily hours.
Whether it is a single faucet or a full repipe, the job types below cover most of what we handle on a given day across Fort Atkinson and the surrounding area. Each one has its own set of causes and its own right way to fix it.
A toilet that runs between flushes is almost always a worn flapper or a float that is not shutting off the fill valve at the right level. Left alone, it wastes a meaningful amount of water and shows up on the bill before it shows up anywhere visible. A toilet that leaks at the base after flushing has usually lost its wax ring seal. Both repairs are straightforward when caught early and more involved when the underlying fittings have corroded.
When water pressure drops throughout the house rather than at a single fixture, the pressure regulator is often the cause. These valves sit on the main supply line and reduce street pressure to a level the home's plumbing can handle. When they fail, pressure either drops too low or climbs too high. We test the regulator, confirm it is the source of the problem, and replace it with the correct unit for the line size and supply pressure.
A pipe that has frozen and split needs to be isolated and replaced before water spreads further into the structure. We shut off the supply, locate the damaged section, and replace it with code-compliant material. In older Fort Atkinson homes with galvanized or original copper, a burst in one section is sometimes a sign that the surrounding pipe is also at risk. We check the condition of the adjacent run and tell you what we find.
The small supply line running to a refrigerator or ice maker is easy to overlook until it fails. A pinhole leak at a compression fitting or a kinked line behind the appliance can drip for a long time before it becomes obvious. We connect new appliances, replace aging lines, and repair fittings that have worked loose over time.
Supply connections and drain hoses on washing machines and dishwashers take more wear than most homeowners expect. A loose connection at the supply valve, a drain hose that has slipped off the standpipe, or a corroded shutoff valve behind the machine are all common calls. We handle new appliance hookups and repair existing connections that have started to leak or drain slowly.
A drain that is running slowly is easier to clear than one that has stopped completely. Kitchen drains accumulate grease and food debris. Bathroom drains collect hair and soap buildup. Main line blockages from root intrusion or accumulated scale are a different category and need a different approach. We assess which part of the system is affected and clear it with the right method, including hydro jetting for stubborn buildup that a standard snake will not move.
Not every plumbing call in Fort Atkinson looks the same, and the situation that leads to a call shapes how we approach it.
Something stopped working and nobody is sure why. A drain is slow but the fixture looks fine. The water pressure has dropped but only in one part of the house. A pipe is wet but the source is not obvious. These calls start with diagnosis: finding the fault before committing to a fix. We check the accessible points first, work outward from there, and explain what we found before any repair begins. We stand behind every pipe and fixture we touch.
A water heater that is aging out, a set of fixtures being replaced during a bathroom update, a whole-house repipe on a property with corroded galvanized pipe: these are jobs that get scheduled in advance rather than called in as emergencies. The scope is clearer from the start, which makes the quote more straightforward. We handle fixture installation, water heater replacement, repiping, and backflow prevention installation on planned timelines as readily as we handle emergency calls.
Before a hard regional winter, properties with exposed pipe runs in unheated crawl spaces, garages, and outbuildings benefit from insulation and winterization work. Sump pump inspection and replacement before spring snowmelt is the same category: work that is far easier to schedule before the problem than after it. The full breakdown of what each type of job involves is on the service page.
When a licensed plumber arrives at a Fort Atkinson property, the first thing that happens is a look at what is actually there. Not an assumption based on the address or the age of the house, but a real assessment of the fixture, the pipe, the drain, or the line that prompted the call.
We explain what we find before we start. That means telling you what the fault is, what fixing it involves, and what it costs. You agree to the work before a wrench comes out. If we find something related that needs attention, we tell you about it and give you the choice. Nothing additional happens without your knowledge and agreement.
After the repair or installation is complete, we test the work. Water runs through the affected lines, connections are checked for leaks, and fixtures are confirmed to be operating correctly before we close out the job.
We serve Fort Atkinson and the communities around it throughout Jefferson County. That includes Jefferson, Whitewater, Hebron, Lake Koshkonong, and Lake Ripley, along with the rural properties in between. Residential and commercial plumbing work across the county, not just inside the city limits.
If you are outside Fort Atkinson proper and are not sure whether we reach your address, call and ask. We will confirm right away.
our drain guide goes into what to expect step by step.
A quote can change if the plumber finds a related problem that was not visible or describable before the work began, such as corroded pipe behind a wall or a fitting that has to be replaced before the repair will hold. We explain what we found and confirm a revised price before continuing. The original quote covers what was described and agreed to at the start.
Yes. Sump pump installation, replacement, and inspection are handled during our regular hours, every day from 6:00 AM to 8:30 PM. A sump pump that has stopped running or is running constantly without shutting off is a call worth making before the next heavy rain or snowmelt event, not after the basement has already taken on water. Call (262) 955-2935 and describe what the pump is doing and we will get it assessed.
Call (262) 955-2935 during our hours, 6:00 AM to 8:30 PM, and explain the situation. We work with property managers and landlords regularly and can coordinate access with a tenant, a building manager, or another authorized contact. The key is getting us the right information on the call so we can make the visit work without a delay.
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.
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.
Call and let us know the situation when you book. We can work within a construction or renovation schedule and coordinate with the general contractor or site manager on timing. Rough-in work, fixture installation, and final connections each happen at different stages of a project, and we plan around those stages rather than treating the job as a single visit.
Shut off the water at the main supply valve as soon as you can locate it. If the leak is near an electrical panel or outlet, do not step into standing water. Move anything nearby that can be damaged by water if there is time to do so safely. When you call, describe where the leak is and whether the water has been shut off. That information helps us arrive with the right materials for the repair.
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.
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. When original materials are no longer manufactured or are not code-compliant, we use current approved materials and make the transition properly. We explain what the replacement material is and why it is the right choice for the repair. The goal is a repair that meets current standards and holds up, not one that matches what was originally installed.
If nobody is available to provide access, we will make contact by phone to work out next steps. Access to the affected area is required to do the work, so if the property is unoccupied we will coordinate with whoever can let the plumber in. When you book, let us know if access arrangements are anything other than straightforward so we can plan accordingly.
Older homes in this area were often built with galvanized steel supply lines that corrode from the inside over time, narrowing the pipe and reducing pressure throughout the house. Fittings and shutoff valves that have not been replaced since the original installation are also more likely to fail or seize when turned. If a home has not had any plumbing work done in a number of years, a call about one problem sometimes turns up a second one nearby that was already developing.
Describing what you are seeing is enough. Cox Plumbing is available every day from 6:00 AM to 8:30 PM. Call (262) 955-2935, tell us what is happening, and we will take it from there.

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