Your Trusted Electrician in Florissant, MO
Kay-Bee Electric has called Old Town Florissant home since 1948. Our shop and dispatch office at 250 St. Francois Street is the same address where the company was founded, three blocks from the Florissant Civic Center and four blocks from St. Ferdinand Shrine. When Florissant homeowners call us, the truck is rolling from across town, not from the next county over. That proximity matters when something goes wrong.
Electrical work in Florissant, MO requires a focus on safety, dependability, and real expertise with historic housing stock. At Kay-Bee Electric, we understand the unique challenges that homeowners and businesses in Florissant face. Many homes in Florissant were built before modern grounding standards, with knob-and-tube wiring, plaster and lath walls, and 60-amp or 100-amp service entrances that were sized for a different century. Whether you’re dealing with flickering lights, planning a major renovation, or upgrading a 1920s home to handle a modern kitchen, our licensed electricians are ready to deliver exceptional service.
Common electrical work we run for Florissant homeowners:
- Knob-and-tube wiring replacement and whole-home rewires for pre-1950s homes
- 60A / 100A to 200A service entrance upgrades on permit with Ameren Missouri coordination
- Ground wire installation for two-prong outlet upgrades to grounded three-prong receptacles (NEC 250)
- Electrical remodeling for kitchen, bath, and basement renovations in historic homes

Excellent job!!Posted on Google Mary WeinmanTrustindex verifies that the original source of the review is Google. Beyond impressed and satisfied with Kay Bee Electric! They were kind, efficient, quick, knowledgeable, trustworthy and did a fantastic job. Corrected the issue without trying to sell us on much more costly work another company had insisted we “had to have” at the cost of thousands of dollars and Kay Bee fixed the issue to code for under $300. HIGHLY recommend!Posted on Google Rebecca CaldwellTrustindex verifies that the original source of the review is Google. I have used Kay Bee three different times and all have been great! We have had a variety of jobs done; total replacement of electrical panel to upgrade it, moved an electrical outlet to higher in the wall for tv, replaced four lights with wafer lighting, and updated all electrical boxes on our main floor). They take care of you in a couple of days and offer a good price. They brought all materials needed, and when I added more tasks, Scott called the main office and had the supplies delivered that day so he could complete the job. You can trust them to take care of you without killing the bank account. This last time, Scott came out and he did a super job. He has worked for the company for over 20 years, that says something about the company.
Frequently Asked Questions
Yes. Whole-home rewires on knob-and-tube homes are one of our most common scopes in Florissant and the surrounding historic neighborhoods. The work usually includes pulling new branch circuits to current NEC requirements (GFCI in kitchens and baths, AFCI in bedrooms and living rooms), upgrading the panel to 200A, replacing the service entrance, and bonding the grounding electrode system to current code. Whole-home rewires are multi-week projects. Because the scope depends entirely on what's behind the walls, we don't quote these over the phone or promise a free walk-through — we price it once we're on site and can see the actual conditions (wall access, existing wiring, panel location). See our Panel Replacement and Ground Wire Installation pages for the supporting scope.
Depends on the scope. A full panel/service replacement or new-construction project gets every Florissant homeowner a free on-site estimate and a written quote before any work starts — that's the only work we quote in advance. Smaller jobs aren't priced over the phone or before the visit; we price them once we're on site. If you're calling about a repair to something that's not working, that's a troubleshooting call, not an estimate — we diagnose the problem first, then quote the fix.
Same-week for most residential calls during business hours (Monday through Thursday 8AM to 4:30PM, Friday 8AM to 3:30PM). Same-day is sometimes available when we have a cancellation. For emergency residential scenarios where the power is out and the utility is fine, see our Restore Power page for what to check on your end while we schedule the visit. We don't operate a 24/7 residential dispatch line, so after-hours calls are scheduled for the next business day.
