Electrical Upgrades
More power, safer wiring, fewer tripped breakers.

Full House Renovations

A renovation is the best time to bring your electrical up to date. Whether you're remodeling one room or the whole house, we plan the layout with you, rough in the wiring, and finish with fixtures and devices, working alongside your contractor or directly with you.
