Dripping faucet fixed. Slow drain cleared. Water flowing right.
Call (608) 941-9789 for a quote and tell us what you are dealing with.
The hardest part of a plumbing problem is knowing when to call, and the answer is usually sooner than you think. A slow drain that gets ignored long enough becomes a main line clog. A dripping faucet that runs for months adds up on the water bill and can signal a deeper valve problem. We handle the full range of common plumbing work for homes and businesses throughout Sun Prairie, and we come with honest recommendations on repairs, never an upsell.
Here is what a typical service call might cover:
We also install frost-free hose bibs, service well pumps and pressure tanks, and set up water softening and treatment systems where the water quality calls for it. Reach out and tell us what the drain is doing.
When the water won't stop, the first call matters. A burst pipe, a major leak, a water heater that went out overnight, or a main line backup that is backing up into the basement all need a fast response and a clear plan. Urgent calls are answered, and the scope of the problem can be talked through before anything is scheduled, covering Sun Prairie and the surrounding area.
We pick up the phone and get it handled.
When you call, someone who knows the trade answers. We scope the job on the phone, ask the right questions about where the water is coming from and how the system is behaving, and confirm the price before anything gets scheduled. You are not waiting for a callback from a stranger who has never seen this kind of job. Reach out and we will get it diagnosed quickly.
Dane County winters are not mild. Temperatures drop hard and stay there, and the freeze-thaw cycles that come with a Wisconsin spring put real stress on supply lines, outdoor fittings, and basement drainage systems. The homes here are mostly built over basements, not slabs, which changes how cold air moves through a structure and where pipes are most exposed. The three services below come up regularly in this area for exactly those reasons.
A Wisconsin cold snap can freeze a supply line inside an exterior wall or in an unheated garage in a matter of hours. When that happens, the pipe may split before it thaws, and the damage shows up fast once water starts moving again. We thaw frozen lines carefully, inspect the affected sections for splits or stress fractures, and repair or replace whatever the freeze damaged. Drain and pipe work is carried out to code on every job, and we do not move on until the repaired section holds pressure the way it should.
Spring snowmelt in Dane County raises the water table quickly, and a basement without a working sump pump is a basement at risk. Whether you are putting in a pump for the first time or replacing a unit that failed at the wrong moment, we assess the pit, route the discharge line correctly, and get the installation done before the next heavy melt. We protect your floors and finishes while we work, and we leave the space clean when the job is done.
Older Sun Prairie housing stock often has exposed supply lines in crawl spaces, attached garages, and utility rooms that were never properly insulated. Before freeze season sets in, we insulate those vulnerable runs and shut off and drain outdoor supply lines so standing water cannot freeze and split the pipe. It is straightforward preventive work that costs far less than a burst pipe repair in January. Let us handle the plumbing and the permits.
Keeping a home dry starts with the pipes behind the walls, and the same is true for a rental unit, an office building, or a retail space. We work with homeowners who need a toilet replaced before the weekend, landlords who need a leaking faucet fixed between tenants, property managers coordinating repairs across multiple units, and businesses that cannot afford a plumbing problem to interrupt operations.
The scope and the price are confirmed on the call regardless of the property type. We do not treat a commercial job differently from a residential one when it comes to how the work gets done. Plumbing work is finished to the local code on every callout, whether we are repiping a single-family home or clearing a main line clog in a commercial building.
We answer when you call. We explain the work. We leave it dry.
If you're not sure your water pressure is where it should be, or you have a drain that has been slow for weeks and you want to know what it will cost to clear it properly, a call is the right first step. We give you a price on the phone once we understand what the job involves, and that price is confirmed before anything is scheduled.
When you call, it helps to know where in the home the problem is, what you are seeing or hearing, and what type of property it is. That information lets us scope the job accurately and give you a rate that reflects the actual work. There is no obligation to schedule until you have the price and you are comfortable with it. Reach out and we will get it diagnosed quickly.
We take calls from across Sun Prairie and the wider Dane County area. Nearby communities we regularly serve include:
If your property is outside this list but still in the area, call and ask. We confirm service availability when you reach out.
A burst pipe, a major supply line leak, a sewer backup spreading through the building, or a complete loss of hot water all qualify. The common thread is that waiting creates more damage or leaves a property without a basic function. We take urgent calls every day from 8:00 AM to 8:00 PM and scope the job on the phone so whoever handles the work arrives knowing what they are dealing with.
A pipe that has frozen may show up as no water flow from a fixture on an exterior wall, or as a bulge or frost on an exposed line in a garage or crawl space. Once the pipe thaws, a split shows up as water flowing from the wall or ceiling.
If you suspect a frozen line, locate your main shutoff and call (608) 941-9789.
We assess the affected section, confirm what needs repair or replacement, and handle the work the same visit when the scope allows.
A sump pump that runs constantly, makes grinding or rattling sounds, or fails to cycle off after heavy rain is telling you it is working harder than it should. A unit that does not activate at all when water enters the pit is the more urgent sign. We inspect the pump, the pit, and the discharge line and tell you whether the unit can be serviced or whether replacement makes more sense before the next melt season.
Sediment buildup at the bottom of the tank is the most common cause in older units. As sediment accumulates, the heating element or burner has to work through it to heat the water above, which reduces efficiency and effective capacity. A flush may restore performance in a unit that is otherwise sound. A water heater that is past its useful life or corroding internally is a replacement job, and we will tell you which situation you are in.
A spike in the water bill without a change in usage, a soft spot or discoloration on a floor or ceiling, a mildew smell in a room with no visible moisture, or a water meter that keeps moving when all fixtures are off are all signs of a hidden leak. We use pressure testing and electronic detection methods to locate the source before any wall or floor is opened. The goal is to find the leak with as little disruption to the structure as possible.
We run a camera through the drain line from a cleanout or fixture access point to see the condition of the pipe from the inside. The camera shows us whether the blockage is a grease buildup, a root intrusion, a collapsed section, or something else. That information determines whether the line needs cleaning, a targeted repair, or a full replacement, and we explain what we find before any work is scoped.
A sewage smell that comes up through a floor drain, a sink, or a toilet is usually a sign that a trap has dried out, a vent line is blocked, or there is a crack or break in the drain line itself. A dried trap is the simplest fix. A blocked vent or a damaged line takes more investigation. We diagnose the source before recommending a repair, because the fix depends entirely on where the odor is coming from.
A targeted repair addresses a single failed or damaged section of pipe. A repipe replaces the supply lines throughout the house, typically when the original pipe material has corroded to the point where individual repairs are no longer a reliable solution. For older Sun Prairie homes with galvanized steel supply lines, a repipe in copper or PEX restores consistent water pressure and eliminates recurring leaks. We assess the system and tell you which approach makes sense.
Whole-house pressure loss usually points to the main supply line, a failing pressure-reducing valve, or significant buildup inside older galvanized pipe that has narrowed the interior diameter over time. A pressure problem that affects only one fixture is a different diagnosis. We check the supply side first, test the pressure at multiple points, and trace the drop to its source before recommending a repair.
Before buying a home, after a major freeze event, when a property has been vacant for an extended period, or when an older home starts showing signs of recurring leaks or pressure problems are all good reasons to have the system looked at. We assess the supply lines, drain lines, water heater, fixtures, and shutoff valves and tell you what the system actually needs. It is more useful than a guess and less expensive than a repair that could have been caught earlier.
A plunger is a reasonable first step for a toilet or a slow sink drain. Chemical drain cleaners are harder on older pipe materials and rarely clear a blockage fully. If the drain is completely stopped, if the problem is affecting multiple fixtures, or if the same drain keeps clogging after you clear it, those are signs the problem is further down the line than a home fix will reach.
Call (608) 941-9789 and describe what the drain is doing.
When we find a condition that does not meet current code during a repair or replacement, we explain what it is and what bringing it up to standard involves before any work proceeds. All drain and pipe work is carried out to the code that local inspectors enforce, and we handle the permit side of that process. You are not left to figure out the code requirements on your own.

Call (608) 941-9789 to talk through what you are dealing with.
| Service Type | What the Job Covers | When to Call | Things to Keep in Mind |
|---|---|---|---|
| Frozen & Burst Pipe Repair | Frozen line thawing, Split pipe repair or replacement, Pressure testing after repair | Properties that lost water flow during a cold snap or found water damage after a thaw | Exterior walls, unheated garages, and crawl spaces are the most common places a Wisconsin freeze damages supply lines |
| Water Softening & Treatment | Softener installation and setup, Whole-house filtration, Water quality assessment | Homes with hard water, scale buildup on fixtures, or water that affects the taste or smell at the faucet | Hard water accelerates wear on water heaters and fixtures, so treatment often extends the life of other plumbing equipment |
| Well Pump & Pressure Tank Service | Well pump diagnosis and repair, Pressure tank inspection and replacement, Pressure switch service | Properties on private wells with inconsistent pressure, short cycling, or a pump that has stopped drawing water | A pressure tank that short cycles puts extra wear on the pump and shortens its service life |
| Toilet Repair & Installation | Running or leaking toilets, Clogged toilets, Full toilet replacement and installation | A toilet that runs constantly, will not flush, or needs to be replaced before a sale or renovation | A running toilet can waste a significant amount of water before the problem becomes obvious on the bill |
| Faucet & Fixture Installation | Dripping faucet repair, Kitchen and bathroom fixture replacement, Utility and laundry room fixtures | Fixture upgrades, persistent drips, or faucets that have corroded or lost pressure | We confirm the shutoff valve is working properly before any fixture work begins |
| Frost-Free Hose Bib Installation | Outdoor faucet replacement, Frost-free bib installation, Supply line connection | Homes with standard outdoor faucets that are vulnerable to freezing in a Wisconsin winter | A frost-free bib drains the line automatically when the faucet is shut off, removing the standing water that freezes and splits the fitting |
| Leak Detection & Repair | Supply line leaks, Pipe leaks behind walls or under floors, Pressure testing and electronic detection | Rising water bills, soft spots in floors or ceilings, or a meter that keeps moving with all fixtures off | We locate the source before opening any wall or floor so the repair is targeted and the disruption is minimal |
| Drain Cleaning & Clog Removal | Kitchen and bathroom drain clogs, Main line blockages, Slow drain diagnosis | Any drain that is slow, gurgling, or fully stopped | A clog that keeps coming back often means the problem is further down the line than a simple clearing will reach |
| Pipe Insulation & Winterization | Insulating exposed supply lines, Shutting off and draining outdoor lines, Crawl space and garage pipe protection | Older homes with unprotected supply runs in garages, crawl spaces, or utility rooms before freeze season | Preventive insulation costs far less than a burst pipe repair in January |
| Sewer & Main Line Service | Sewer line cleaning and clearing, Camera inspection, Root intrusion and blockage repair, Line repair and replacement | Multiple drains backing up at once, sewage odors, or a main line that has not been inspected in years | A camera inspection shows exactly what is in the line before any repair is recommended |
| Water Pressure & Shutoff Valve Repair | Whole-house pressure diagnosis, Pressure-reducing valve service, Shutoff valve repair and replacement | Low pressure throughout the home, a shutoff that will not close fully, or pressure that fluctuates unexpectedly | A failing pressure-reducing valve is one of the most common causes of sudden whole-house pressure loss |
| Water Heater Repair & ReplacementMost Popular | Tank and tankless units, No-hot-water calls, Sediment flush and element repair, Full unit replacement | Homes or businesses with inconsistent hot water, an aging unit, or a heater that stopped working | Replacement work is carried out to the local code on every callout, and we confirm the right unit size before anything is ordered |
| Sump Pump Installation | New pump installation, Failed pump replacement, Discharge line routing | Basements at risk from spring snowmelt or a pump that failed during the last heavy rain | Dane County snowmelt raises the water table quickly, and a failed pump in April is one of the more common calls we take |
| Garbage Disposal Service | Disposal repair, Full replacement and installation, Jam clearing | A disposal that hums but does not spin, leaks from the bottom, or has stopped working entirely | Most disposals that hum without spinning have a jam that can be cleared without a full replacement |
| Emergency Plumbing | Burst pipe response, Major leak containment, Sewer backup, No-hot-water urgent calls | Any situation where waiting creates more damage or leaves a property without a basic function | We are available every day from 8:00 AM to 8:00 PM and scope urgent jobs on the phone so the work starts without delay |
What are the signs that a water heater needs to be replaced rather than repaired?
A unit that is corroding at the tank seams, leaking from the base, or producing discolored water is typically past the point where a repair makes sense. A heater that has lost significant capacity and does not respond to a sediment flush is usually in the same category. We assess the unit on the call and tell you whether the problem is serviceable or whether replacement is the more reliable path forward.
What is the difference between a clog in a single fixture and a main line blockage?
A clog in one fixture affects only that drain. When multiple fixtures back up at the same time, or when flushing a toilet causes water to come up in a nearby sink or tub, the blockage is further down in the main line. Main line clogs require different tools and a different approach than a fixture-level clearing, and we diagnose which situation you are in before recommending a method.
What is the difference between a tank water heater and a tankless unit?
A tank water heater stores a fixed volume of hot water and keeps it ready. A tankless unit heats water on demand as it flows through the unit, so there is no stored volume to run out of. Tankless units take up less space and can handle continuous demand well, but they require a certain flow rate and may need a gas line or electrical upgrade depending on the installation. We walk through the options based on your household size and how the hot water is used.
Cause Found Before Anything Is Replaced
We diagnose the source of the problem before recommending a repair or replacement. Honest recommendations on repairs, never an upsell, is how we approach every job.
How do tree roots get into a sewer line, and what does the repair involve?
Roots follow moisture, and a sewer line that has any small crack or a slightly loose joint is enough of an entry point. Once inside, roots grow into the flow path and catch debris until the line slows or backs up completely. We run a camera to confirm root intrusion before recommending a repair. Depending on how far the roots have grown and whether the pipe wall is structurally sound, the fix may be a targeted cutting and clearing or a section of pipe replacement.
How long does a water heater replacement typically take?
Most water heater replacements are completed in a few hours. The timeline depends on the unit type, whether the gas line or water connections need any adjustment, and whether a permit is required for the installation. We confirm what the job involves on the call.
What can hydro jetting clear that a standard drain snake cannot?
A drain snake breaks up or pulls out a blockage, but it does not clean the pipe wall. Hydro jetting uses high-pressure water to scour grease, scale, and debris from the interior of the pipe, which restores closer to full flow capacity. It is particularly useful on lines that have accumulated years of grease buildup or where the same stretch of pipe keeps clogging after repeated snaking.
Code-Compliant Work on Every Job
All drain and pipe work is carried out to the code that local inspectors enforce. We handle the permit side of that process so you are not left to figure it out on your own.
How do I handle a running or leaking toilet while I wait for a repair visit?
A toilet that runs continuously is wasting water but is not an emergency in most cases. You can shut off the supply valve behind the toilet at the base of the wall to stop the flow until we get there. A toilet that is leaking at the base or overflowing is a different situation.
If water is spreading onto the floor, shut off the supply valve and call (608) 941-9789 so we can assess how quickly it needs to be addressed.
How do you respond to a burst pipe, and what should I do before you arrive?
Locate your main water shutoff and close it as soon as you suspect a burst pipe. That stops water from continuing to flow into the damaged section. Move anything that can be damaged away from the wet area if it is safe to do so. When you call, we ask where the break appears to be, what the water is doing, and whether the shutoff is accessible. That information lets us arrive with the right materials and scope the repair accurately.
Clean and Respectful Workmanship
We protect your floors and finishes while we work and leave the space clean when the job is done. The work area should look the same as we found it, minus the plumbing problem.
What causes a faucet or fixture to drip after it is turned off?
A dripping faucet is almost always a worn internal component. In a cartridge faucet, the cartridge itself degrades over time. In a compression faucet, the seat washer wears down. In a ball faucet, the springs and seats inside the ball assembly wear out. The fix is usually a component replacement rather than a full fixture swap, though a faucet that is corroded or has failing threads may be a candidate for replacement. We diagnose which situation applies and explain the options before any work starts.
What does a whole-house repipe involve, and how long does it take?
A repipe replaces the supply lines throughout the home, typically when the original pipe material has corroded to the point where individual repairs are no longer a reliable solution. Older Sun Prairie homes with galvanized steel supply lines are the most common candidates. The work involves opening walls and ceilings at strategic points to run new copper or PEX throughout the system. The timeline depends on the size of the home and how the existing lines are routed, and we walk through the scope with you before anything is scheduled.
What should I do if my water pressure drops suddenly and the problem seems to affect the whole house?
A sudden whole-house pressure drop is worth investigating promptly. Shut off any running fixtures and check whether the pressure-reducing valve near the main supply line is accessible. Do not attempt to adjust it yourself.
Call (608) 941-9789 and describe when the drop started and whether anything changed recently, such as recent work on the supply line or a new appliance connected to the water supply.
We trace the cause from the supply side and confirm the repair before work begins.
