Expert Well Service & Repair in Dousman, WI & Metro Milwaukee
A well that stops working is an immediate problem. There's no workaround, no delay that makes sense—when the water is off, everything stops. For a household, that's a serious disruption. For a farm or commercial facility, it's an operational crisis. Herr Well Drilling, Inc. has been providing well service and repair throughout Dousman, WI and Metro Milwaukee since 1964, and this is the part of the work where response time and accurate diagnosis matter most.
We handle the full range of well service and repair needs—pump failure, pressure loss, water quality changes, aging infrastructure, and routine inspections—for residential, agricultural, and commercial customers across Southeast Wisconsin. Our crew knows the well systems and local geology of this region in a way that a generalist contractor or out-of-area service company simply doesn't. That familiarity shows up most clearly in the diagnostic phase, where pattern recognition built over decades in one market makes a real difference.
What We Do
Our well service and repair work covers every major component of a private water well system. That includes fixing and replacing well pumps for both submersible and jet pump systems, installing new well pumps and upgrading equipment, installing and replacing pressure tanks, inspecting wells for regular maintenance and real estate sales, repairing and rehabilitating damaged wells, providing well abandonment services that follow Wisconsin DNR rules, diagnosing and troubleshooting system issues, testing water quality to find contamination or chemical problems, improving water quality with treatment system advice, and testing pumps to check how well the system works.
We work on all major brands and types of well pump equipment and carry the pulling equipment needed to access deep submersible pumps. When a property has lost water entirely, we prioritize getting someone out there.
Diagnosis First
This is usually where repair calls go sideways with less experienced contractors—replacing the most obvious component without understanding why it failed and then watching the new component fail for the same reason.
A pump that burned out because of a waterlogged pressure tank will burn out again if the pressure tank doesn't get replaced. A pump that's cycling rapidly isn't necessarily failing—it may be signaling a pressure system problem that a pump swap won't fix. We run pump tests, examine pressure system components, evaluate water quality when the symptoms point that direction, and look at the well itself when necessary. That process takes a little more time upfront and prevents many expensive surprises later.
Our crew has worked through virtually every well problem that occurs in Waukesha County and the surrounding region. The intermittent issues, the gradual pressure declines, and the seasonal fluctuations that only make sense in the context of local aquifer behavior—those kinds of diagnostic experiences don't come from a manual.

Well Pump Repair and Replacement
Submersible pump failure is the most common well emergency we respond to throughout the Metro Milwaukee area. Complete loss of water, a pump that runs but won't build pressure, rapid cycling, or unusual sounds from the pump or pressure tank all point toward a pump or pressure system problem. We diagnose before we pull—because sometimes the pump is fine and the issue is elsewhere in the system. When replacement is the right answer, we install equipment sized appropriately for the well's yield and the property's actual demand.
Well Pump Installation
New pump installations are needed for new wells, system upgrades, and properties transitioning between pump types. The critical piece here is matching pump capacity to the well's sustainable yield. Oversizing a pump relative to what the well can reliably deliver causes drawdown problems and accelerated pump wear. We size these systems to work with the well, not against it.
Pressure Tank Installation and Replacement
The pressure tank is the component that most well owners don't think about until it fails — at which point the pump is usually cycling every few seconds and wearing itself out rapidly. A waterlogged pressure tank is one of the most common causes of premature pump failure we see. Replacing a tank that's showing signs of failure before the pump goes is a straightforward repair that prevents a much more expensive one.
Well Inspections
We perform impressively inspections for routine maintenance purposes and for real estate transactions where a property with a private well is changing hands. A professional inspection covers wellhead and casing conditions, pump performance through a flow test, pressure system function, and a basic water quality screen. We provide written documentation of findings—which matters both to buyers trying to understand what they're purchasing and to sellers who want to demonstrate a well-maintained system.
Well Abandonment
Old wells that are no longer in use need to be properly abandoned under Wisconsin DNR requirements. This isn't optional—an improperly abandoned well creates a direct pathway for surface contaminants to reach groundwater, and the liability sits with the property owner. Herr Well Drilling handles abandonment in full regulatory compliance, including grouting from bottom to top and filing the required DNR abandonment report.
Water Quality Testing and Treatment
We facilitate water quality testing in a laboratory and can advise on treatment options based on results. Testing is recommended for all new wells, for wells that have been rehabilitated, and for households with specific health concerns. While our focus is on the well and pump system rather than whole-house treatment installation, we help property owners understand their water chemistry and connect with appropriate treatment solutions for whatever the testing reveals.

Frequently Asked Questions
How do I know if my well pump has failed?
Complete loss of water, a pump that runs without building pressure, rapid on-off cycling, or unusual sounds from the pump or pressure tank are the main indicators. Any of these are worth a prompt service call—the longer a failing pump runs, the more damage it can do to itself and surrounding components.
How long does pump replacement take?
Most submersible pump replacements wrap up in a single day. Deeper wells take more time to pull and reinstall—we'll give you an accurate estimate of the timeline before the work starts.
What is the lifespan of a well pump?
Typically 10 to 25 years, depending on water quality, usage volume, and whether the pressure tank is functioning correctly. A waterlogged pressure tank that causes rapid cycling can shorten that lifespan to just a few years.
How often should a well be inspected?
Annually, for year-round residences, it is ideal. At minimum, a professional inspection every three to five years catches developing problems before they turn into emergency calls.
What does a well inspection include?
Physical condition of the wellhead and casing, pump performance testing, pressure system function, and a basic water quality assessment. We provide written documentation of everything we uncover.
Is well abandonment required in Wisconsin?
Yes. Wisconsin law requires non-used wells to be properly abandoned under DNR guidelines. The contamination risk from an improperly sealed well is real, and the liability sits with the property owner. We handle abandonment in full compliance.
Can you test my well water quality?
Yes. We facilitate laboratory testing and offer advice on treatment options based on results. Testing is recommended for new wells, rehabilitated wells, and households with health-related water quality concerns.
Do you service wells installed by other contractors?
Yes. We work on all major types and brands of well pump equipment regardless of who originally installed the system. Our concern is getting the water system working correctly—not who did the original job.
