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.

Yes. Whole-home rewires on knob-and-tube homes are one of our most common scopes in Cottleville 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 Cottleville 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.
