MEK
Industrial electrical tools on a steel workbench

Family owned & operated

Brought the Standards.
Kept the Grit.

A family company launching in Sioux Falls — industrial I&C, premium home work, and discreet specialized cleanup.

Why MEK exists

New name in South Dakota. Not new standards.

Simon spent 18+ years inside power plants. Klemen ran quality and process in automotive. Mateja runs finance and the cleanup division. The work is split on purpose — so a homeowner never sits in an industrial RFQ, and a plant engineer never gets a handyman form.

Owners on the job

We are not a franchise and we do not rotate strangers from an app. The people on this page show up.

Industrial first

Home and cleanup work run under the same loop, code, and documentation habits used on generation equipment.

Disclosed up front

Licensing for the South Dakota entity is in process. Team credentials are public. No surprises in the quote.

Leadership

Three people. Three tracks. One standard.
