"KJM Plumbing, Kurt, responded quickly to my request for a quote on replacing our leaking water heater. He quoted installing a high quality, Bradford White unit at a reasonable price. The plumber who did the full installation was a very skilled, professional and friendly worker. The final invoice had no unexpected charges and included a nice breakdown of the major portions of the project. I highly recommend KJM Plumbing, for work in the Madison, WI area."

"Very quick response to receive a quote. They arrived on time and did awesome work! They left me with a new tub, surround and fixtures and cleaned up all the mess. New tub looks great! I would definitely hire again. Thank You!"

"My service technician, Mason, arrived on time and got straight to work. He was very thorough and explained everything that he was doing as he was doing it, and prior to doing it. He arrived with another associate, and both men were very nice. I like the fact that they’re thoroughly explain everything and don’t try to pressure you into buying anything at the very end. He fully explained that in a few months I would be due for another filter, but that everything else was OK. He also explained what would happen if I did not change the filter which was helpful. I would highly recommend Cardinal if you are in need of heating or air conditioning repair or service."

"The plumber was very friendly and professional. The price they quoted me was over $200 less than other plumbers for the same level of service. I was very pleased with the competence of the plumber. He took the time to explain the controls to me, the type of salt I should use, and how much salt for my new water softener. He was an hour late, however he finished the job in less time than I was quoted."

FAQs for sump pump or interior foundation drains installation projects in Madison, WI

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
