Your Trusted Electrician in St. Louis, MO
Electrical work in St. Louis, 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 in St. Louis face. Many homes in the City 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 work we run for St. Louis homeowners includes knob-and-tube wiring replacement, 60A or 100A to 200A service entrance upgrades on permit with Ameren Missouri coordination, ground wire installation per NEC 250 for two-prong outlet upgrades, electrical remodeling for kitchen and bath renovations in historic homes, and outdoor lighting for historic curb appeal.

Frequently Asked Questions
Yes. Whole-home rewires on knob-and-tube homes are one of our most common scopes in the City of St. Louis and the historic neighborhoods (Central West End, Tower Grove, Soulard, Lafayette Square, Compton Heights). 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 single fixture swap is the smallest residential call we run. A whole-home rewire on a historic City of St. Louis home is in the larger end of the residential spectrum. A full panel/service replacement or new-construction project gets every St. Louis 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. Typical drive from our Florissant headquarters to most City of St. Louis neighborhoods is 15 to 25 minutes via I-270 or I-70. 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 residential calls are scheduled for the next business day.
