THE SAME PLUMBER FROM QUOTE TO CLEANUP.

Big outfits send whoever is free. Ernstmeyer Plumbing Co. LLC does not work that way. Thadd Ernstmeyer holds Wisconsin Master Plumber license 996751 and stands on the job himself, which means the person who prices your work is the person who does it and answers for it afterward. Nothing gets handed off to a subcontractor you have never met.


Small repair or full commercial installation, the standard does not move: pull the permit, do the work right, and clean up before we go.

  • Weekend service is available at a higher rate than standard weekday service.

WATER DAMAGE COSTS MORE THAN THE FIX.

Most of what we repair started as something small. A supply line weeping behind a vanity. A toilet running through the night. A sewer lateral holding water in a belly that roots found three summers ago. By the time flooring cups or a ceiling stains, the plumbing bill is the cheap part of the project. We would rather find it with a camera and a pressure gauge than meet you after the drywall comes down, which is why we look at the whole system instead of the one fitting that failed.

WE LEAVE THE JOB SITE LOOKING UNTOUCHED.

Plumbing work happens in the parts of a home people do not think about until someone is standing in them. Boots come off or get covered. Furniture gets moved back. Cut access panels are finished, not left ragged behind a plate. We explain what we found, what we changed, and what to watch, then we take our mess with us. Nothing is left for you to sort out later.

WHAT WE DO

OUR PLUMBING SERVICES

12 service lines, one crew, and one standard behind all of them. Here is the work we take on for homes, businesses, and builders across Sauk County and the counties next door.

Residential Plumbing

Everything behind the walls of a house, from a dripping laundry faucet to a full repipe in copper, PEX, or CPVC. We work in occupied homes daily and plan the water shut-off around your schedule, not ours.


  • Fixture, faucet, and valve replacement 
  • Copper, PEX, and CPVC repiping

Commercial Plumbing

Apartment buildings, car washes, clinics, and restaurants run on systems that cannot go down during business hours. We schedule around your operating window and size the piping for real demand rather than the minimum a plan sheet allows.


  • After-hours and weekend scheduling 
  • Backflow assemblies and grease waste lines

Plumbing Repair

Leaks, clogs, weak pressure, noisy pipes, and fixtures that never quite worked right. We diagnose before we quote, so you are paying to fix the cause rather than replacing parts until the symptom happens to disappear.


  • Leak location and pipe repair

Emergency Plumbing

A burst line, a failed water heater, or a water service break will not wait for an appointment slot. Call and you reach Thadd, not a dispatch queue, and after-hours work carries no premium on top of the repair itself.


  • Burst pipes and active leaks
  • Water service breaks and failed water heaters

Water Heater Installation & Repair

Storage tanks in gas and electric, tankless units, and the repairs that buy a good tank a few more years. We size to actual household demand and set the venting, relief piping, and shut offs to code.


  • Tank and tankless installation
  • Thermostat, element, and valve repair

Sewer Line Repair & Replacement

Roots, bellies, offset joints, and collapsed clay all look the same from inside the house. A camera run tells us which one you have, and we repair or replace only the section that has actually failed.


  • Video camera sewer inspection
  • Spot repairs and full lateral replacement

WHAT REEDSBURG NEIGHBORS SAY

ERNSTMEYER PLUMBING REVIEWS.

The reviews that stay with us are the ordinary ones. A same-day water heater when everyone else quoted a week. A holiday weekend call answered. A rental property managed from a thousand miles away, with hot water restored and remote control set up so it would not happen again.

★★★★★

I was thoroughly impressed by the remarkable level of care and foresight shown throughout the entire experience. Every stage reflected a deep understanding of what makes a process truly effective and enjoyable. The final outcome was exceptional and left me with complete satisfaction.


Andrew A.

★★★★★

Many plumbers to chose from, but the honest, friendly, knowledgeable approach is hard to beat. They have helped me out many times after being introduced during a 4000 sqft home build a few years back.

faq

frequently asked
questions.

These are the questions that come up most often on service calls around Reedsburg. If yours is not here, send it through the contact page and we will answer it plainly.

  • Why is my water bill suddenly higher than usual?

    A jump with no change in habits almost always means a leak. Check the toilet flappers first, since a silent one can pass hundreds of gallons a day, then look for damp spots along the service line in the yard.

  • How do I find the main water shut-off valve in my house?

    On a municipal service it sits where the line enters the basement, usually near the meter on the street-facing wall. Homes on a well have it at the pressure tank. Label it now, before you need it in a hurry.

  • What causes low water pressure throughout the whole house?

    Whole-house pressure loss usually traces to a failing pressure-reducing valve, a partly closed main shut-off, or scale narrowing older galvanized pipe. If only the hot side is weak, the water heater or its shut-off is the more likely culprit.

  • Is hard water bad for my plumbing?

    Hard water will not corrode pipe, but the scale it leaves behind shortens water heater life, clogs aerators and shower heads, and coats the inside of fixtures. Softening slows all of that down and cuts soap use noticeably.

  • Why do my drains smell like sewage?

    A dry trap is the usual answer. Guest bathrooms and floor drains that go unused let the water seal evaporate, and sewer gas comes straight up. Pour a gallon of water down each one and see if the smell clears.

  • How do I keep pipes from freezing in a Wisconsin winter?

    Keep heat above 55 degrees in every room with plumbing, open vanity doors on exterior walls, and disconnect garden hoses before the first hard freeze. Pipes in unheated crawl spaces and rim joists need insulation or heat tape.
