What we do
Residential &
commercial electrical
From a dead outlet to a new panel, and from a single light fixture to a shopping center's camera circuits. Done to code and cleaned up before we leave.
Troubleshooting & Repair
Lost power to part of the house, breakers that keep tripping, flickering lights. We test our way to the actual fault, then fix it.
Lighting & Fans
Light fixtures, recessed lighting, ceiling fans and exterior lights, including high ceilings and replacing what's already up there.
Outlets & New Circuits
Add an outlet, move a switch, or run a dedicated circuit for a mini-split, appliance, shop or home office.
EV Chargers
Level 2 charger installs in the garage or driveway, on a circuit sized for your car and checked against what your panel can carry.
Commercial
Retail, office and shopping-center work: receptacles, camera and network power, exterior enclosures and lighting, scheduled around your business hours.

Customers say
Five stars, every review
“They were amazing about everything from the time they arrived. Very efficient and knowledgeable about how to resolve my issue. Quickly diagnosed my issue and fixed it in no time. I would highly recommend and I will be using them for all of my electrical needs in the future.”
“I had Tharp Electrical install an outdoor enclosure and receptacle for cameras on a major shopping center as well as an additional outlet at the backboard for internet. They worked with the changing schedule we had to adjust to. Their quality of work was top notch. I was extremely happy with the service I received.”
