Since 1952

One truck, one pipe threader.

Walter Kowalczyk came home from the Army, apprenticed with a South Side plumber, and opened his own shop in 1952. We still have the pipe threader.

Seventy-four years.

  1. 01

    1952

    Walter opens the shop in his garage on the South Side, with one truck and a hand pipe threader. Most of the work is coal-to-oil boiler conversions and new bathrooms in old houses.

  2. 02

    1971

    Stan takes over. The work shifts to gas boilers, copper repipes, and the first wave of basement bathrooms.

  3. 03

    1990s

    The steam boilers Walter installed start coming back for their second replacement. Stan starts keeping a notebook of every one.

  4. 04

    2009

    Mike takes over the license. The notebook becomes a spreadsheet, and it has more than three thousand Milwaukee boilers in it.

  5. 05

    2024

    Danny starts his apprenticeship. Four generations have now worked in the same garage.

What hasn’t changed

We still give you the bad news before the bill. We still tell you when something can be repaired rather than replaced. And the phone number is still answered by somebody named Kowalczyk.
