When something goes wrong with the plumbing in your Thiensville home, you want to know what the visit covers before anyone shows up. Cox Plumbing handles the full range of residential and commercial plumbing work: drain cleaning, leak detection and repair, water heater service, fixture replacement, sewer and main line work, sump pump installation, garbage disposal installation, and emergency calls when a problem will not wait. Every job is carried out by licensed plumbers. You get a price before anything is scheduled, and you know what the work involves before a wrench comes out.
Thiensville is a small town, and the housing stock here reflects that. Older homes on their original pipework, basements that need working sump systems, and supply lines that have never been touched since they were installed are all common in a place this size. Property managers and homeowners alike call us when something breaks and when they want to get ahead of a problem before it turns into one. Working here keeps us accountable to the neighbors we serve.
The price depends on what the fault turns out to be and what has to come apart to reach it. A dripping faucet that needs a washer swapped is one job. A dripping faucet that turns out to have corroded fittings behind the wall is a different one. We do not know which it is until we look, which is why we scope the work before we schedule it.
When you call, we ask enough questions to understand what you are dealing with. That lets us give you a realistic quote on the phone before anyone drives out. If we open something up and find the situation is more involved than it looked, we explain what we found and confirm the revised price before we continue. You are not agreeing to a blank check when you book.
What moves a quote up or down is the condition of the existing pipework, how accessible the affected section is, and whether related fittings or connections need replacing at the same time. Age of the plumbing matters too. Older pipe that has been in the ground or behind a wall for decades sometimes reveals more once work begins. We tell you what we find and let you decide how to proceed.
Plumbing calls in a town like Thiensville tend to fall into a few distinct situations. A repair call is different from a replacement job, and both are different from a planned installation. Knowing which one you are dealing with shapes everything that follows.
Slow drains, low pressure, a pipe that is making noise, a water heater that runs but does not deliver consistent heat - these are all fault-finding jobs before they are repair jobs. We locate the source first. For leaks inside walls or under floors, that means checking access points and working outward until we find where the water is coming from. For drain problems, it means understanding whether the blockage is at a single fixture or further down the line. Getting this right the first time is what keeps the repair from coming back.
Some plumbing holds up for decades. Some does not. When a water heater is aging and losing efficiency, when a toilet keeps running no matter what has been replaced, or when corroded galvanized pipe is behind a third slow-pressure call in as many months, a replacement is the cleaner answer. We explain the options, confirm the price, and carry out the work. The service page carries the full breakdown of what replacement jobs involve and what to expect from each.
Not every call is an emergency. Homeowners in Thiensville planning a bathroom update, adding a garbage disposal, or replacing aging fixtures before they fail can schedule installation work around their own timeline. We work with contractors on larger projects and with individual homeowners who want the plumbing side handled by licensed plumbers. Same-day appointments are often available for urgent calls. For planned work, earlier scheduling gives you more flexibility on timing.
A sewer backup or a drop in water pressure can mean two very different things depending on where the problem sits. A clog in a drain line inside the house is one job. A damaged or root-intruded sewer line running from the foundation out to the street connection is another. Both cause the same symptoms at the fixture. Finding out which one you are dealing with is the first step.
We handle both. Inside the property, that means drain cleaning, clog removal, and pipe repair. Outside, it means the sewer run from the house out to the main. We clear blockages in that line, inspect it, and repair or replace sections that have cracked, shifted, or been compromised by root intrusion. We do not service the septic tank or the drain field. Our work stops at the line itself.
The distinction matters for cost and for planning. A drain cleaning inside the house is a shorter job than a sewer line repair under the yard. If the symptoms suggest the problem is underground, we will tell you that on the call and explain what the inspection involves before you commit to anything.
We are available every day from 6:00 AM to 8:30 PM. Same-day appointments are often available, and for urgent situations, we prioritize calls where water is actively causing damage or where a household or business has lost a critical fixture. When you call, you reach someone who takes the details of the job and gives you a quote before anything is scheduled.
For tenants and businesses that need to stay open, we work around the situation. That means being clear about what the job involves, how long it is likely to take, and whether any part of the property will be without water while the work is done. You get that information before we arrive, not when we are already there.
Scheduled calls get a confirmation before the visit. Emergency calls are handled as quickly as the situation allows. We do not promise arrival windows we cannot keep. What we do promise is that the job is scoped and priced before a wrench comes out, and that a licensed plumber handles the work. Simple scheduling. Competitive rates. Water back fast.
Whether it is a single fixture or a line that runs under the yard, the goal is the same: the water goes where it is supposed to go and stops where it is supposed to stop. The jobs below are the ones that come up most often in a place like Thiensville.
When symptoms suggest a problem in the sewer line, a camera inspection tells us what we are dealing with before we recommend a repair. A small waterproof camera goes into the line through a cleanout or toilet flange and shows us the interior condition in real time. Root intrusion, cracked pipe, offset joints, and heavy buildup all look different on camera, and knowing which one we are dealing with determines the right fix.
Where the pipe condition and the access allow it, trenchless repair methods let us fix a damaged sewer line without opening up the full length of the yard above it. This is not the right approach for every situation. When it is, it reduces disruption significantly. We assess the line condition from the camera inspection first and explain whether trenchless is the right call before any digging begins.
A backflow preventer stops contaminated water from reversing into the supply line. These devices are required in certain plumbing configurations and need periodic inspection to confirm they are functioning correctly. We install new backflow prevention devices and service existing ones. If yours has not been looked at in some time, or if you are not sure whether your property has one, a call is the right place to start.
A toilet that rocks, leaks at the base, or has cracked porcelain is not a repair candidate. Replacement is the right answer, and it is a straightforward job when handled correctly. We pull the old unit, inspect the flange, replace the wax ring, and seat the new toilet properly before we test it. A toilet that is not seated correctly will leak again. We stand behind every pipe and fixture we touch.
A dripping faucet wastes water and gets worse over time. A tap that has seized and will not close fully is a more urgent problem. Both are jobs we handle in the same visit. For older faucets where the internal parts are corroded beyond a simple repair, replacement is often the cleaner answer. We assess the condition on site and tell you what makes sense before we proceed.
We serve Thiensville and the communities nearby throughout Ozaukee County. That includes Mequon, Cedarburg, Brown Deer, River Hills, and Bayside. Whether the job is in the heart of town or in one of the surrounding communities, residential and commercial plumbing work across the area is what we handle.
If you are outside Thiensville and are not sure whether we reach your address, call and ask. We will confirm right away.
the page about drains and pipes describes what happens once the 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.
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.
We start with the most likely routes based on the age and layout of the building, then use access points like cleanouts, shutoff valves, and fixture connections to work outward. For underground or concealed lines, we use inspection tools to locate the run without unnecessary excavation. If a property has no drawings, that is not unusual and it does not prevent us from finding and fixing the problem.
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.
Older homes in a small town like Thiensville often have original supply lines, galvanized fittings, and drain configurations that have never been updated. That means recurring low pressure, joints that corrode faster than newer materials would, and fixtures that are harder to match when they need replacing. None of that makes the work impossible. It does mean a thorough look at what is behind the walls before committing to a repair plan.
No. Opening access to concealed pipework is part of the job when it is needed. We assess what access is required once we see the situation, and we explain what that involves and what it costs before we proceed. If you already know a pipe is behind a wall or under a cabinet, mention it when you call so we can plan accordingly.
We are open every day from 6:00 AM to 8:30 PM. Scheduling within those hours is straightforward, and same-day appointments are often available for urgent situations. If your business needs drain service before opening or after closing, call and describe the timing and we will work out what is possible within our available hours.
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.
Any leak that is actively spreading water into a wall, floor, or ceiling, or that you cannot stop with an isolation valve, should be treated as urgent. Sewage backing up into the home, a burst pipe, or a water heater that is leaking from the tank itself also fall into that category. Call us during our hours, 6:00 AM to 8:30 PM every day, and we will assess the situation and work to get someone out the same day.
The most useful steps are checking that any exposed supply lines in unheated spaces are insulated, confirming that outdoor faucets and hose bibs are properly shut off and drained, and making sure the sump pump is running correctly before snowmelt season arrives. If any of those have not been looked at recently, or if you are not sure what condition they are in, a call before the season turns is the right move. Catching a problem in October is much easier than dealing with it in January.
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.
Cox Plumbing is available every day from 6:00 AM to 8:30 PM. Call (262) 955-2935 for a quote, and we will scope the job before anything is scheduled. For planned work, including pipe insulation, sump pump installation, and fixture upgrades before winter sets in, earlier is better. The calls pick up once the season turns. One call. One plumber. One fair price.

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