  • Breakers that trip frequently or won't reset. Lights that flicker when you run appliances. A fuse box instead of a breaker panel. Burning smell or scorch marks near the panel. You're adding an EV charger, hot tub, or major appliance. Your home is 30+ years old and has never had an upgrade.

  • Most residential panel upgrades are completed in one day. We schedule the permit, coordinate the utility disconnect, do the work, and pass the inspection — all handled by our crew. You'll have power back the same day in most cases.

  • Yes. Spark Shark handles the permit application, the utility coordination, and the final inspection. You don't have to deal with any of it. Every panel upgrade we do is fully permitted and code-compliant.

  • Panel upgrade costs vary based on panel size (100A, 200A, 400A), the age of your wiring, and whether a subpanel is needed. We give you an upfront price before any work starts — no surprises. Call us for a free estimate: (262) 587-5887.

Hear what the buzz is all about

I would give them a 10. VERY knowledgeable and professional. I needed a hazard issue looked at asap and he fit me in same day. He also did an inspection to let me know if there were any issues I needed to address. He also answer all of my questions on a couple things I was unsure of. I will definitely recommend him. Also very clean. wore booties and cleaned up the mess. very reasonably priced!

We were extremely impressed with the quality of service we received from SPARKSHARK. The customer service is outstanding as is the work. We had outside light poles installed, garage sconces that needed to be custom mounted and indoor ceiling lights installed. We highly recommend SPARKSHARK for their excellent customer service, their quality of work, their knowledge and expertise and getting the job done right.
