Our Clients Testimonials

Learn More About Our Family

Family Owned

Kay-Bee Electric was founded after World War II in 1948 by John Kohnen and Jack Behlmann and has been headquartered in Florissant for 75 years. Working mostly in the northern suburbs of St. Louis, MO, Kay-Bee established itself as a mainstay in the local community and contributed to the rapid growth of the area.

Frequently Asked Questions

St. Louis City and County, St. Charles County, Jefferson County, Lincoln County, Warren County, and Franklin County. If you’re on the edge of all that and not sure whether we cover you, just call. We’d rather tell you over the phone than send a truck that has to turn around in your driveway.

Yes. Licensed in Missouri, with full liability insurance and workers’ comp. If you need a current certificate of insurance before we start (property managers and commercial clients almost always do), just ask. We keep them ready.

Both, roughly fifty-fifty. Residential calls are mostly service work, panel upgrades, rewires, and additions. Commercial is tenant build-outs, restaurant kitchens, retail spaces, and small office work. We do take on heavy industrial and high-voltage work.

Since 1948. The shop was founded just after WWII by John Kohnen and Jack Behlmann, and it’s stayed family-owned ever since. A lot of what we know about older St. Louis homes (knob-and-tube, old fuse-box conversions, plaster-wall fishes) comes from actually being behind those walls for decades, not from a textbook.

Honestly, anything from one dead outlet to a full house rewire. Most weeks that means panel replacements, EV chargers, generator hookups, ceiling fans, and dedicated circuits for big appliances like ovens or hot tubs. Plus a steady stream of breakers that won’t stop tripping and code fixes when a house is going on the market. If it’s electrical and it’s inside a building, it’s probably us.

We do, for the real ones. No power to part of the house, burning smell at the panel, a breaker that won’t stay set, water in a light fixture. Call the main line and tell whoever picks up that it’s an emergency, and we’ll get a truck out as fast as we can. After-hours rates are higher than normal. We’ll tell you the number before anyone is dispatched, never after.

Yes, any time the job legally needs one. Panel changes, service upgrades, additions, EV chargers, generator transfer switches, most rewires. We pull the permit, schedule the inspector, and meet them on site so you don’t have to take time off work. If a job is small enough that no permit is needed, we’ll tell you that straight up instead of charging for one you don’t need.

Yes. One year on workmanship from the day we finish. If something we wired fails because of how we wired it, we come back and fix it, no charge. Manufacturer warranties on the parts themselves (panels, breakers, EV chargers, fans) run separately and are usually longer. We’ll register them in your name when the manufacturer requires it.
