Some plumbing problems get scheduled. A water heater that has been running rough for a season, a bathroom fixture that needs replacing before a renovation wraps up, a toilet that has been running longer than it should. Those calls come in during business hours, with time to talk through the options. Then there are the calls that do not wait: a pipe that has let go overnight, a basement drain backing up while guests are in the house, a water heater that stopped working sometime before dawn. Cox Plumbing handles both kinds, every day from 6:00 AM to 8:30 PM, and same-day appointments are often available when something cannot wait until tomorrow.
Lake Geneva draws a mix of year-round residents, seasonal property owners, and rental properties that turn over on a schedule nobody controls. The plumbing work that comes out of that mix is just as varied. Whether it is a landlord dealing with a tenant call on a Sunday morning or a homeowner who has been putting off a repipe for two seasons, we take the job, scope it on the phone, and send a licensed plumber to handle it. One call. One plumber. One fair price.
Not every plumbing call looks the same, and the work that follows depends almost entirely on what the situation actually is. A dripping faucet and a flooded utility room are both plumbing problems. What they call for is completely different.
Most calls start here. Something stopped working, or something started doing something it should not. A toilet that runs between flushes, a faucet that drips after the handle is fully closed, a drain that is slow in one fixture and fast in every other. We locate the source, explain what we find, and fix it. For problems that are harder to pin down, such as a leak inside a wall or a pressure drop that appears at some fixtures but not others, we work through the likely causes before recommending a fix. The job is scoped and priced before a wrench comes out.
Some jobs are not repairs. A water heater that has reached the end of its useful life, a toilet that has been patched twice and needs to come out, a section of galvanized pipe that has corroded past the point of repair. These are replacement jobs, and they follow a different process. We confirm what is coming out, what is going in, and what the installation involves before anything is scheduled. Fixture installation, tankless water heater upgrades, garbage disposal replacement, and full repiping all fall into this category. The full breakdown of what we handle lives on the services page.
Not every call is a problem. Some are improvements: a homeowner adding a bathroom, a rental property getting updated fixtures before a new tenant moves in, a seasonal property being winterized before the owner heads south. Planned work gets scheduled around the property and the people in it. We coordinate the scope on the phone and confirm the price before anything is booked.
Older homes in the Lake Geneva area were built with pipe materials that have not aged well. Galvanized steel corrodes from the inside out, narrowing the pipe over time and reducing water pressure throughout the house. Polybutylene, installed widely in homes built through the 1990s, becomes brittle and fails at the fittings. When either material is the problem, spot repairs stop making sense after a point. We assess what is in the walls, explain the scope of a repipe, and give a price before any work begins.
When a sewer line or underground supply line has cracked, shifted, or been intruded by roots, the repair does not always require digging up the yard. Trenchless methods allow us to repair or line a damaged section of pipe from access points at either end, which is less disruptive and faster to complete in many situations. We inspect the line first to confirm what we are dealing with, and we explain the options before recommending an approach.
A toilet that rocks, leaks at the base after flushing, or has a crack in the porcelain needs to come off the floor. Reseating involves pulling the fixture, replacing the wax ring and inspecting the flange, and resetting the toilet so it sits correctly. Full replacement follows the same process with a new fixture going back in. Both are straightforward jobs that take a few hours when the flange is in good condition.
A toilet that runs between flushes is almost always a worn flapper or a float that is not shutting off the fill valve correctly. It wastes more water than most people expect, and it shows up on the water bill before it shows up anywhere else. A toilet that leaks at the base is typically a failed wax ring. Both repairs are quick, and catching them early costs less than the accumulated water waste. We'll have your drains running again in no time.
Gas line work requires the same licensed plumbers who handle water and drain work, and the standard for the job is the same. We install gas lines for new appliances, repair lines that have developed a leak, and extend existing runs when a range, dryer, or outdoor grill connection needs to be added. If you smell gas, leave the building and call from outside. For everything else, call us during business hours and we will scope it on the phone.
Scheduling a plumber shouldn't be complicated. We are available every day from 6:00 AM to 8:30 PM, and when you call, you reach someone who can take the details of the job and get something on the schedule. Same-day appointments are often available for urgent situations. For calls that cannot wait, we prioritize based on what is happening and get a licensed plumber moving.
For rental properties and seasonal homes, we work around occupancy. If a tenant needs to be home, we coordinate the window with whoever is there. If a business has to stay open, we work around the hours that matter. We confirm the appointment window when you call so the property is ready when the plumber arrives.
Working here keeps us accountable to the neighbors we serve. That means doing the work the way it was described on the phone. Whether the job is a quick toilet repair or a full sewer line inspection, the process is the same: call, get the price, schedule, and let a licensed plumber take care of it.
A single slow drain is usually a clog in that fixture's trap or drain line. Hair, grease, and soap buildup are the most common causes, and a standard cleaning clears most of them. When the clog is deeper in the line, hydro jetting sends a high-pressure water stream through the pipe to cut through buildup that a drain snake cannot reach. We'll have your drains running again in no time.
When every drain in the house is backing up at the same time, the problem is not in any single fixture. That is a main line issue, and it needs to be treated as one. We inspect the sewer line to find the blockage or the damage, clear it, and assess the condition of the pipe to determine whether the problem is likely to come back. A main line backup that gets cleared without an inspection often returns, because the cause is still in the pipe.
The difference matters because the fix is different. One slow drain gets cleaned. A full backup gets inspected. Call and describe what you are seeing, and we will tell you on the phone which situation you are dealing with.
The price for a plumbing job depends on what the job actually involves. A toilet repair and a sewer line replacement are both plumbing, but they do not cost the same, and the factors that move the price are different for each. When you call, we ask about the situation, scope the work, and give you a price before anything is scheduled. You know what you are paying for before a licensed plumber walks through the door.
What changes a quote is usually what the plumber finds once the work is underway. A pipe that looked accessible from the outside may run through a finished wall. A fitting that was supposed to be in good condition may need replacing before the repair will hold. When that happens, we explain what we found and confirm the revised price before continuing. We do not proceed with additional work without your agreement.
Backflow prevention, sewer line inspection, fixture installation, and repiping all follow the same process. Call for a quote, get the price up front, and ask what it covers. Simple scheduling. Competitive rates. Water back fast.

It depends on the scope and layout of the property. A full repipe requires the water to be off for periods during the work, and access to walls and ceilings is often needed. We can walk through the job with you before scheduling to discuss what disruption is realistic and how to plan around occupied units. Some properties can be done in sections to reduce the impact on tenants.
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.
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. 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.
Either the property owner or the tenant can call us directly at (262) 955-2935. We take the details of the situation on the phone, confirm the scope and price, and get a licensed plumber scheduled. For urgent situations, same-day service is often available. We coordinate the appointment window with whoever needs to be present at the property, so the repair gets handled without unnecessary back-and-forth.
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.
Same-day service is available throughout the area we cover, including smaller communities. If you are not sure whether your address falls within our service area, call (262) 955-2935 and we will confirm right away. Urgent calls are handled the same way regardless of where in the service area the property is located.
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.
Yes. Seasonal properties have specific needs, including winterization before the owner leaves, de-winterization in the spring, and repairs that come up between stays. We work with property owners and the people managing those homes to schedule around occupancy, and we can coordinate with a caretaker or property manager if the owner is not in town. Call and describe the situation and we will work out the right approach.
We handle underground supply line and sewer line repairs, including runs that go beneath driveways or other surfaces. The scope of that kind of job depends on what the line is, how deep it runs, and what access is available. Where trenchless methods are an option, we use them to minimize disruption to the surface. Call and describe the situation and we will tell you what the job involves before anything is scheduled.
Cox Plumbing takes calls every day from 6:00 AM to 8:30 PM. Describe what is happening, get a price on the phone, and we will get a licensed plumber scheduled. Same-day appointments are often available for urgent situations.

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