Cox Plumbing - Plumber in Waukesha

From century-old homes to new commercial builds, we handle the kind of plumbing work that keeps a property running. That means drain cleaning and clog removal, leak detection and repair, water heater service, toilet and faucet installation, sewer line work, garbage disposals, repiping, and water pressure diagnostics. Every job is carried out by licensed plumbers who know what code-compliant work looks like and what it takes to get it done right.

Working here keeps us accountable to the neighbors we serve. That accountability shows up in how we scope a job, explain the work, and follow through once the wrench comes out. Whether you're a homeowner dealing with a slow drain or a property manager coordinating repairs across multiple units, we're a straightforward choice for homeowners and property managers who want the work done without the runaround.

Call and we'll get the water running right.

Drain Cleaning, Leak Repair, and the Everyday Calls We Handle

Whether it's a single faucet or a full repipe, the most common plumbing calls share a pattern: something stopped working, and it needs to be fixed today. We cover all of it.

Drains and Clogs

Slow drains and full clogs show up in kitchen sinks, bathroom drains, and main lines alike. We clear them with the right tool for the job, including hydro jetting for stubborn buildup in sewer drains and main lines. If a clog keeps coming back, we'll tell you why and what it takes to fix it for real.

Leak Detection and Pipe Repair

A dripping faucet is easy to spot. A water line leak inside a wall or underground is not. We locate the source, assess the damage, and repair or replace the affected section. Catching a pipe leak early keeps a small problem from turning into a large one, and we'll walk you through what we find before any work begins.

Water Heaters

No hot water is one of the most disruptive plumbing problems a household or business can face. We repair and replace both tank and tankless water heaters. If your unit is aging or underperforming, we can assess whether a repair makes sense or whether a replacement is the better call. Tankless water heater installation is available for customers looking to upgrade.

Toilets, Faucets, and Fixtures

A running toilet, a dripping faucet, or a fixture that needs replacing - these are jobs we handle every day. We also install garbage disposals, repair sink connections, and swap out fixtures in kitchens and bathrooms. We stand behind every pipe and fixture we touch. One call, and a plumber is on the way.

Sewer and Main Line Service

Getting your water flowing again is easier than you think when you know who to call. Sewer line problems range from a slow main drain to a full backup, and the cause is not always obvious from the surface. We clean, inspect, repair, and replace sewer lines, and we handle main water line repair when a break or leak affects your supply.

A sewer line inspection is often the first step - it tells us what we're dealing with before we commit to a repair plan. Where the situation allows, trenchless sewer repair is an option that avoids unnecessary excavation. Main line clogs, sewer backups, and line damage from tree roots or shifting soil are all jobs we take on regularly across Waukesha County.

We'll have your drains running again in no time.

Plumbing Built for Waukesha's Climate

Waukesha County winters are hard on plumbing. Sub-freezing temperatures, heavy snowmelt, and older housing stock with uninsulated supply lines create a specific set of problems that show up every year. The three services below address what local conditions actually cause - not what looks good on a list.

Frozen and Burst Pipe Repair

Wisconsin winters push pipe temperatures below freezing in unheated crawl spaces, exterior walls, and garages. When a pipe freezes, the pressure that builds inside can split it open before the thaw even begins. When you call with a burst or frozen pipe, we assess the situation, thaw what can be thawed safely, and repair or replace the damaged section. Speed matters with a burst pipe - the longer water runs unchecked, the more damage it does.

Sump Pump Installation

Waukesha County's clay-heavy soils don't drain quickly, and spring snowmelt puts real pressure on basement walls and floors. A working sump pump is the first line of defense against water intrusion in a basement. We install new sump pumps, inspect existing pits and discharge lines, and replace failed units. If your pump is running constantly or not running at all, that's a call worth making before the next hard rain.

Pipe Insulation and Winterization

Older Waukesha homes often have supply lines running through unheated spaces - garages, crawl spaces, exterior walls - that were never properly insulated. Before winter sets in, we can wrap exposed pipes, inspect shutoff valves, and flag anything that's likely to cause a problem when temperatures drop. A shutoff valve that hasn't been used in years is also worth inspecting and replacing if it's stuck or corroded. Winterization is one of those jobs that's easy to skip until a pipe bursts at 2 AM in January.

Shutoffs Labeled Before We Go

Emergency Plumbing When You Need It

Scheduling a plumber shouldn't be complicated. When something goes wrong fast - a burst pipe, a sewer backup, no hot water, a major leak, an overflowing toilet - you need someone who picks up the phone and can get the situation under control. We're available every day from 6:00 AM to 8:30 PM, and same-day service is available for urgent calls.

The price is confirmed before work starts. You'll know what the job involves and what it costs before anything is scheduled. Same-day service. Upfront pricing. Licensed plumbers. We'll have your drains running again in no time.

Clogs, Leaks And Low Pressure

Plumbing for Property Managers and Commercial Clients

From century-old homes to new commercial builds, the scale of the job changes but the standard doesn't. Property managers, apartment owners, restaurant operators, and office building managers all deal with plumbing problems that can't wait. We handle commercial drain cleaning, commercial water heater installation, fixture installation across multiple units, sewer line service, repiping, water pressure diagnostics, and backflow prevention. Work is carried out by licensed plumbers who understand the demands of a commercial property - faster turnaround, clear communication, and repairs that hold up under heavier use. Call and we'll get the water running right.

Transparent Pricing and Straightforward Scheduling

Getting a plumbing quote shouldn't feel like a negotiation. When you call, we scope the job and give you a price before anything is scheduled. You know what you're getting and what it costs before a wrench comes out. That's how it works for a routine drain cleaning, a water heater replacement, a sewer line repair, or a full repipe.

For bigger jobs - repiping, sewer line replacement, water heater upgrades - a clear quote up front matters most. We explain what the work involves, what it will take to complete it, and what the price covers. Simple scheduling. Competitive rates. Water back fast. One call, and a plumber is on the way.

Frequently Asked Questions

What areas does Cox Plumbing serve beyond Waukesha?

We serve Waukesha and the communities throughout Waukesha County, including Pewaukee, Brookfield, Menomonee Falls, Oconomowoc, Mukwonago, New Berlin, and Delafield. If you are outside Waukesha proper and are not sure whether we reach your address, call and we will confirm right away. We handle residential and commercial work across the county, not just in the city limits.

Yes. We work with homeowners, landlords, property managers, restaurant operators, and commercial building managers across Waukesha and the surrounding area. The scope of the job changes, but the process is the same: we scope the work, give you a price before anything starts, and send licensed plumbers to do the job. Whether it is a single fixture in a bathroom or a multi-unit building with a sewer backup, we handle it.

We are open every day from 6:00 AM to 8:30 PM, including Saturdays and Sundays. Weekend calls are handled on the same schedule as any other day, and same-day appointments are often available for urgent situations. Call (262) 955-2935 and we will get the details and work to fit you in.

Call (262) 955-2935 during our hours, which are every day from 6:00 AM to 8:30 PM. Describe what is happening and we will give you a quote on the call before anything is scheduled. Same-day appointments are often available, so the sooner you call, the better the chance we can get someone out the same day.

When every drain is backing up at the same time, the problem is almost always in the main sewer line, not in a single fixture. Shut off water use in the house if sewage is coming up through a drain or toilet, and call us right away. We handle main line clogs and sewer backups and can often get someone out the same day. Do not run water or flush toilets until the line is cleared.

For routine plumbing work, we can often schedule within a day or two depending on the current call volume. Same-day appointments are frequently available for urgent situations. Call and describe what you are dealing with, and we will give you a realistic window based on the schedule that day.

Pricing is based on the work involved, not on square footage or fixture count. When you call, we scope the job and give you a price for what needs to be done. A single drain cleaning is priced as a single drain cleaning whether the house is a two-bedroom bungalow or a large commercial building.

The most common reason a job costs more than the initial estimate is that the plumber finds a related problem once the work is underway, such as corroded fittings behind a wall or a second section of damaged pipe. We do not proceed with additional work without explaining what we found and what it costs first. You agree to any change in scope before the work continues.
