Who runs A.J. Alberts

Steve Grohn has owned A.J. Alberts since 1996. He lives in Woodbury, raised his kids through Woodbury Public Schools, and treats every job like it is in his own neighborhood, because most of the time it is.

Day-to-day operations are led by Jason Wallraff, a master plumber, Hudson Wisconsin resident, and former U.S. Marine. Jason is also a licensed RPZ backflow technician and licensed boiler technician.

James Walker, a master plumber and U.S. Navy veteran, leads our south metro service in Lakeville, Burnsville, Apple Valley, Farmington, and Rosemount.

We employ 10 plumbers total, including 5 master plumbers. That is unusually deep bench strength for a locally owned plumbing operation of our footprint, and it means every job is led by a credentialed plumber, not an apprentice.

The “0 commissioned salespeople” policy

The most important number about A.J. Alberts is zero. We do not pay our technicians based on the size of the ticket. Our techs are paid to diagnose your problem and recommend what you actually need. Nothing more.

Ask what problem a proposed repair addresses, what evidence supports it, and what alternatives are available before approving the work.

What we do

Water conditioning is a core service, including softening, iron and odor assessment, water filtration, and reverse osmosis drinking-water systems.

We also provide general residential plumbing: leaks, fixtures, sump pumps, water service lines, gas lines, water heaters, boilers, and drain cleaning.

We do not take on commercial new construction or large industrial projects. We focus on doing residential plumbing exceptionally well.

Our service area

Primary depth in Washington County (Woodbury, Cottage Grove, Stillwater, Lake Elmo, Mahtomedi, Hugo, Hastings) and the St. Croix Valley (Hudson, River Falls).

Active across the broader Twin Cities Metro: Ramsey County, Dakota County, Hennepin County, and Anoka County. See our service areas hub for the full city list, or the water quality map for our city-by-city water context.

How to book

Call 651-738-0580 or schedule online. Most appointments are booked within a day or two. For emergencies (active leaks, no heat in winter, burst pipes), call immediately and we will prioritize you.

We offer a free basic in-home water test. The free basic in-home test checks hardness, iron, chlorine, pH, total dissolved solids, and alkalinity, plus nitrate for well-water customers. It does not measure PFAS or establish drinking-water safety. A.J. Alberts offers separate paid PFAS testing for municipal-water and private-well customers. We collect and submit the sample and explain the laboratory report. Ask about the scope and price when booking.
