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.
Depends on your panel size and current load. A typical 200A panel in a 2,200 to 3,200 sqft St. Peters home with central AC and a gas dryer usually has room for a 50A EV circuit. A 100A panel almost always needs an upgrade before adding 50A. We run the load calculation once we're out for the job and give you the honest answer in writing before any work starts — panel capacity isn't something we quote over the phone. See our Install Electric Car Charger and Panel Replacement pages for the technical detail.
Depends on the scope. A single fixture swap is the smallest residential call we run. A whole-home panel replacement plus EV charger plus generator install is in the larger end of the residential spectrum. A full panel/service replacement or new-construction project gets every St. Peters 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 residential calls are scheduled for the next business day.
