Dave's Plumbing & Heating handles full-service residential and commercial plumbing across Waukesha and the surrounding Waukesha County area. Whether you own a home, manage rental units, or run a commercial property, we are here when something goes wrong and when you are planning ahead. We are open daily from 6:30 AM to 10:30 PM, with same-day service available for calls that cannot wait. Licensed plumbers handle every job, from a dripping faucet to a burst pipe on a January night. Built for homeowners. Ready for property managers. Ready for your pipes.
Keeping a home dry starts with the pipes behind the walls, and that work covers more ground than most people realize until something goes wrong. We handle the full range of everyday plumbing: drain cleaning and clog removal, leak detection and repair, water heater repair and replacement, toilet and faucet and fixture installation, sewer and main line service, garbage disposals, water pressure diagnostics, shutoff valve repair, and whole-house repiping. Residential or commercial, single-family home or multi-unit rental, we bring experienced plumbers on every callout.
You're talking to someone who knows the area and the older pipes in it. Waukesha's housing stock includes homes of all ages, and older properties especially can carry galvanized or cast-iron plumbing that has reached the end of its useful life. When a repair turns into a conversation about pipe replacement, we walk you through what is involved and what it costs before anything is scheduled. Code-compliant plumbing is the baseline on every job, whether we are fixing one fixture or repiping a full floor.
Property managers and landlords rely on us to keep rental units functional without a lot of back-and-forth. We work efficiently, communicate clearly about what we found and what we did, and get the job closed so your tenants are not waiting around. We'll handle the pipes so you don't have to.
A slow drain is an early warning. Kitchen lines collect grease and soap over time. Bathroom drains catch hair and soap scum. Main line blockages can back up every fixture in the building at once. We clear clogs at the source, whether that means a simple drain cleaning or running a line through a stubborn main line blockage. If a drain is giving you trouble, call for a quote and we will tell you what we are dealing with before we start.
Hearing a running toilet or a drip behind the wall? Leaks caught early stay small. Left alone, they cause structural damage, mold, and a water bill that climbs every month. We locate the source, whether it is a pinhole in a supply line, a joint that has let go, or a water line that needs replacing, and we repair or replace what is needed. When a pipe bursts, we treat it as the emergency it is. We'll get your water flowing again fast.
No hot water is one of those problems that stops a household cold. We repair and replace both tank and tankless water heaters, handle sediment buildup and thermostat issues, and install new units when a water heater has run its course. Domestic hot water is squarely in our lane. If your water heater is struggling or has given out entirely, call us and we will confirm what the job involves and what it costs before we schedule the visit.
A running toilet wastes more water than most people expect, and a leaking faucet does the same. We repair and replace toilets, fix running and leaking faucets, and install new fixtures in bathrooms and kitchens. Shower and bathtub plumbing, kitchen sink work, outdoor faucet repair, and hose bib replacement all fall in this category. If you are updating fixtures during a remodel or just replacing something that has worn out, we handle the installation and make sure everything is properly connected and leak-free.
A blocked or damaged sewer line affects every drain in the building. We clean, repair, and replace main lines and sewer lines, clearing blockages and addressing damage to the line itself. Our work stops at the line. We do not service septic tanks or drain fields, but we handle everything on the house side of that connection: the pipe, the cleanout, and the repair or replacement when the line needs it.
A garbage disposal that hums but does not spin, leaks under the sink, or trips the reset repeatedly is usually a straightforward repair or replacement. We install, repair, and replace disposals in kitchens of all sizes.
When a home's pipes are corroded, undersized, or failing in multiple spots, repiping is often the more practical answer than repeated repairs. We handle whole-house repiping and targeted pipe replacement, working with you on scope and timeline.
Low water pressure and faulty shutoff valves are more than minor annoyances. We diagnose pressure problems, repair and replace shutoff valves, service pressure-reducing valves, and repair main water shutoffs. If the pressure in your home has dropped or a shutoff valve will not fully close, that is worth a call.
Wisconsin winters are not gentle, and Waukesha County homes deal with conditions that push plumbing systems hard. Deep sub-freezing temperatures, freeze-thaw cycles through late winter and early spring, and significant snowmelt all create specific risks for pipes, basements, and outdoor plumbing. The services below address the problems that come up most often here.
When temperatures drop well below freezing, pipes in exterior walls, crawl spaces, garages, and unheated areas are at real risk. A frozen pipe that thaws on its own is lucky. One that bursts sends water into the structure fast. We respond to burst pipe calls and handle emergency pipe repair, working to shut off the water, address the damage, and restore service. If you suspect a pipe has frozen but has not yet burst, call before it does. We'll sort out what is going on and tell you what the repair involves.
Most Waukesha County homes sit on basements, and spring snowmelt combined with seasonal rain puts those basements at risk of flooding. A properly installed sump pump moves groundwater out before it becomes a problem. We install new sump pumps, replace units that have failed, and repair pumps that are running but not keeping up. If your basement has taken on water or your current pump is aging, it is worth getting a quote before the next heavy melt season arrives.
Staying ahead of plumbing problems keeps your home dry through a Wisconsin winter. Exposed pipes in crawl spaces, garages, and along exterior walls are the most vulnerable. We insulate supply lines and winterize outdoor plumbing, including frost-free hose bib installation, to reduce freeze risk before cold weather sets in. When insulation is not enough because the pipe itself is too far gone, we move into pipe replacement or repiping to give the system a sound foundation going forward.
Getting your plumbing problem handled starts with a quick call. We are open daily from 6:30 AM to 10:30 PM for emergency plumbing repairs, including burst pipes, major leaks, no hot water, and backed-up drains that cannot wait for a scheduled appointment. Same-day plumbing service is available, and we handle urgent calls across Waukesha and the surrounding area. Pick the date. We do the plumbing. We clean up after.
When something goes wrong fast, call (262) 955-2282. We will confirm what we can do and get you a quote before anything is scheduled.
Doing plumbing work right matters, and we'll help you get it right, whether you own one home or manage a portfolio of properties. Homeowners call us for repairs, upgrades, and emergencies. Landlords and apartment owners count on us to respond quickly and keep units habitable. Commercial property managers need plumbing work done on a timeline that does not disrupt tenants or operations.
We handle plumbing for home renovations and remodels, including rough-in work, fixture installation, and water line reconfiguration. For renovation and commercial projects that involve gas-line work, we service gas lines, handle gas line repair, and install new gas lines where the project calls for it. We stand behind every pipe and fixture we touch, and we communicate clearly at every stage so you know what was done and why.
Beyond the core services, we also install and repair backflow preventers, which protect the water supply from contamination and are required in certain commercial and irrigation applications. Water softener installation is a common request in this part of Wisconsin, where hard water is the norm and mineral buildup shortens the life of water heaters, fixtures, and appliances. We handle water line repair and replacement, plumbing fixture replacement, and a range of other work that does not always fit a neat category. Call with what you have and we will tell you whether it is something we handle.
Simple booking. Clear pricing. Sound, lasting pipes.
When you call for a quote, we ask about the problem, confirm what the job involves, and give you the price before anything is scheduled. You know what you are paying for before a licensed plumber shows up at your door. We do not lock you into a schedule until the price makes sense for you.
We are open daily from 6:30 AM to 10:30 PM, including weekends. If you need a plumber on Saturday, Sunday, or any day of the week, call and we will tell you what is available. Plumbing repair costs vary by job, and the honest answer is that the quote happens on the phone, not on this page. What we can tell you is that the price is confirmed before we schedule, and the work is performed by licensed plumbers on every visit.
We serve Waukesha as our primary market and cover the broader Waukesha County region, including Brookfield, Pewaukee, Oconomowoc, Menomonee Falls, New Berlin, and Mukwonago. If you are searching for a plumbing contractor near you in this part of Wisconsin, we are the call to make. Whether the job is in the city or out in the county, we cover the area and handle the full range of residential and commercial plumbing work.
The most common signs are inconsistent water temperature, water that takes much longer than usual to heat up, discoloration or a metallic taste in the hot water, and visible corrosion or moisture around the base of the unit. A tank that makes popping or rumbling sounds is often dealing with sediment buildup at the bottom, which reduces efficiency and can shorten the unit's life. If you are noticing any of these, call for a quote and we will assess whether a repair makes sense or whether replacement is the more practical path.
A reduction in hot water capacity is usually caused by sediment accumulation at the bottom of the tank, a failing heating element, or a thermostat that is no longer calibrated correctly. In some cases, the unit has simply reached the end of its service life and can no longer keep up with demand. We diagnose the cause during the service call and give you a clear answer on whether a repair resolves it or whether a replacement is the better option.
A clog in a single fixture, like one sink or one toilet, is usually localized to that drain. When multiple fixtures back up at the same time, or when flushing a toilet causes water to back up in a nearby tub or sink, the blockage is most likely in the main sewer line. We assess the situation when we arrive and clear the blockage at the right point in the system, whether that is a branch drain or the main line itself.
A camera is run through the cleanout or an access point into the sewer line, sending back a live video feed that shows the condition of the pipe interior. This lets us locate blockages, identify root intrusion, spot cracks or collapsed sections, and confirm whether a repair or a replacement is the right call. It takes the guesswork out of diagnosing a sewer line problem and gives you a clear picture of what is actually happening underground.
Water stains on ceilings or walls, a persistent mildew or musty smell in a room with no obvious source, soft spots in flooring near plumbing fixtures, and an unexplained spike in your water bill are all common indicators. Hidden leaks can cause significant structural damage before they become visible, which is why catching them early matters. We locate the source and repair it cleanly, whether it is a supply line, a fitting, or a section of pipe that has given out.
A spot repair addresses a single failed section of pipe, which makes sense when the rest of the system is in good condition. A repipe replaces the supply lines throughout the home, which is the right call when a system has corroded pipes in multiple locations, recurring leaks, or persistent low pressure that does not improve after individual repairs. We assess the overall condition of the plumbing and give you a clear recommendation on which approach makes more sense for your situation.
Recurring leaks at different points in the system, consistently low water pressure throughout the home, rust-colored water, and pipes that are visibly corroded or scaled on the outside are all signs that the system may be past the point of individual repairs. Many older Waukesha homes still have galvanized steel supply lines that corrode from the inside out over time. A service call gives us a look at what the pipes are actually doing and whether a repipe is the practical answer.
We start with a call to understand the scope, then confirm the pricing and timeline before scheduling the work. For a water heater replacement, the visit typically involves removing the old unit, installing the new one, connecting the supply lines and any gas or electrical connections, and testing the system before we leave. A whole-house repipe is planned in stages, and we walk you through what access is needed, what to expect during the job, and how long the work will take before anything is scheduled.
A tank water heater stores a set volume of hot water and keeps it heated continuously. A tankless unit heats water on demand as it flows through the system, which eliminates the standby heat loss of a tank but requires adequate flow rate and gas or electrical capacity to work correctly. We install and repair both types, and if you are considering switching from a tank to a tankless system, a call will help you understand what the upgrade involves for your home's existing setup.
For most repairs involving supply lines, fixtures, or water heaters, yes. The main shutoff or a local shutoff valve will need to be closed while the work is in progress. We handle the shutoff as part of the job and restore water service before we leave. If you have a shutoff valve that is stuck or no longer closes fully, let us know when you call, as that affects how we approach the repair.
We start by asking detailed questions on the phone to narrow down the likely cause before arriving. On site, we check the fixtures, supply lines, and drain system in the affected area, and use camera inspection or pressure testing when the source is not immediately visible. The goal is to find the actual cause rather than treat the symptom, so the repair addresses the problem rather than just the most visible result of it.
Outdoor supply lines, hose bibs, and pipes in unheated spaces are vulnerable to freezing when temperatures drop well below freezing, which happens regularly in Waukesha County every winter. Underground lines can also shift during freeze-thaw cycles in late winter and early spring, which can stress joints and cause leaks to develop. Insulating exposed pipes and installing frost-free hose bibs before winter sets in is the most straightforward way to reduce that risk.
We are open every day from 6:30 AM to 10:30 PM and take emergency calls alongside scheduled work during those hours. Same-day plumbing service is available for burst pipes, major leaks, sewer backups, and water heater failures. Call (262) 955-2282, describe what is happening, and we will tell you what we can do and when.
Permit requirements depend on the type of work and whether it falls under local jurisdiction rules for the city or the county. When a job requires a permit, that is part of the conversation when we scope the work, before anything is scheduled. We confirm what applies to your address and your specific job so there are no gaps in the process.
Dave's Plumbing & Heating is open daily from 6:30 AM to 10:30 PM. Call (262) 955-2282 for a quote or to schedule a service call. We'll sort out what you need, confirm the price, and get licensed plumbers on the job. Simple booking. Clear pricing. Sound, lasting pipes.

| Drain Cleaning & Clog Removal | kitchen and bathroom drain clearing, main line blockages, slow drain diagnosis | Homes or rentals with recurring slow drains or a full backup | A slow drain is often an early sign of a developing main line problem, catching it early keeps the repair smaller |
| Leak Detection & Repair | supply line and joint leaks, pinhole pipe repair, hidden leak location | Anyone with an unexplained water bill spike or visible moisture with no clear source | Hidden leaks cause structural damage before they surface, locating the source early limits the repair scope |
What actually causes a drain to back up, and when does it become a main line problem?
Most single-drain clogs come from grease and soap buildup in kitchen lines or hair and soap scum in bathroom drains. Those are localized and clear up with a drain cleaning. When multiple fixtures back up at the same time, or when flushing a toilet pushes water into a nearby tub or sink, the blockage is most likely in the main sewer line rather than a branch drain. We assess the situation on arrival and clear the clog at the right point in the system.
How do tree roots damage a sewer line, and how do you fix it?
Tree roots follow moisture and naturally migrate toward sewer lines, entering through small cracks or loose joints in older pipe. Once inside, they grow and eventually block the line or cause it to collapse. We use camera inspection to confirm root intrusion and locate the affected section. Depending on the extent of the damage, the fix is either clearing the roots and repairing the pipe or replacing the damaged section of line entirely.
What causes low water pressure throughout the house, and is it a serious problem?
Low pressure affecting the whole house rather than a single fixture usually points to a failing pressure-reducing valve, a partially closed main shutoff, or corrosion and mineral buildup inside older galvanized pipes restricting flow. In some cases, the municipal supply pressure has dropped. We diagnose the cause during the service call and repair or replace what is responsible. A shutoff valve that will not fully open or a pressure valve that is out of range is worth addressing before it gets worse.
Same-Day and Emergency Availability
We are open every day from 6:30 AM to 10:30 PM and same-day service is available for calls that cannot wait. Burst pipes, major leaks, and sewer backups are handled the same day you call.
When is it worth calling a plumber instead of attempting a DIY fix?
A simple drain cleaning with a store-bought snake or a toilet flapper swap is something many homeowners handle on their own. The call to bring in a licensed plumber makes sense when the problem involves supply lines, shutoff valves, water heaters, sewer lines, or anything behind a wall or under a slab. Mistakes on pressurized supply lines or drain connections can cause water damage that costs far more than the original repair. If you are not sure what you are dealing with, a call costs nothing and gets you a straight answer.
What should I do immediately if a pipe bursts in my home?
Shut off the water at the closest shutoff valve, or at the main shutoff if you cannot isolate the affected line. If the water is near electrical outlets or panels, do not enter the area until the power is off. Then call us. We handle burst pipe calls during our daily hours of 6:30 AM to 10:30 PM, and same-day service is available. We will ask what is happening, confirm what we can do, and get a licensed plumber to you as quickly as the schedule allows.
How does a sump pump failure lead to a flooded basement, and what are the warning signs?
A sump pump fails to remove groundwater from the pit before it overflows into the basement. The most common failure points are a burned-out motor, a stuck float switch that prevents the pump from activating, a clogged intake, or a power interruption during a storm. Warning signs include a pump that runs constantly without cycling off, one that does not run at all when the pit is filling, unusual noise during operation, or visible rust and corrosion on the unit. If your pump is aging or showing any of those signs before melt season, it is worth a call.
Work Performed by Licensed Plumbers
Every job, from a single faucet repair to a whole-house repipe, is handled by licensed plumbers. We do not send out unqualified help on jobs that require trade knowledge.
What does hydro jetting clear that a standard drain snake cannot?
A drain snake breaks through a clog and restores flow, but it does not clean the pipe walls. Hydro jetting uses high-pressure water to scour the interior of the line, removing grease buildup, mineral scale, and debris that a snake leaves behind. For lines with recurring clogs or heavy buildup, jetting addresses the root cause rather than just clearing the immediate blockage. We recommend it when camera inspection shows significant accumulation along the pipe walls.
How long does a water heater replacement typically take?
A standard tank water heater replacement is usually completed in two to three hours. That covers removing the old unit, installing the new one, connecting the supply lines and the gas or electrical connections, and testing the system before we leave. A tankless installation can take longer depending on whether the existing gas line or electrical service needs to be upgraded to meet the unit's demand. We confirm the timeline when we scope the job so you know what to plan for.
Experienced With Older and Newer Homes
Waukesha's housing stock runs the full range, and we are familiar with the galvanized and cast-iron systems in older homes as well as the materials and standards in newer construction.
What is the risk of ignoring a running or leaking toilet?
A toilet that runs continuously can waste several hundred gallons of water a day, which shows up directly on your water bill. A leaking base or supply line connection can cause floor damage and mold growth over time. Most running toilet repairs involve the flapper, fill valve, or flush handle assembly and are straightforward to fix. A leaking base often means the wax ring seal has failed and needs to be replaced. Neither is a problem worth deferring, and both are quick calls.
How do I know if my water pressure issue is related to the shutoff valve or something deeper in the system?
If pressure dropped suddenly, check whether the main shutoff or a branch shutoff was recently bumped or partially closed. A valve that is only partially open restricts flow and drops pressure quickly. If the valve is fully open and pressure is still low, the cause is more likely a failing pressure-reducing valve, mineral buildup in older pipes, or a supply issue upstream. We work through the system from the most accessible point inward and confirm the cause before recommending a repair.
How is pricing determined for a plumbing job, and when do I find out what it costs?
You get the price on the call, before anything is scheduled. We ask about the problem, confirm what the job involves, and give you the rate before a licensed plumber is dispatched. Plumbing repair costs vary by job type, materials, and scope, so the honest answer is that the quote happens on the phone rather than on this page. What we can tell you is that the price is confirmed before we schedule, and there are no additions after the fact that were not discussed upfront.
Call (262) 955-2282 to get a quote on any of the services above, and we will walk you through what the job involves and what it costs before anything is scheduled.
