Your local Longmont electrician. From historic Old Town bungalows to new builds in Prospect, we provide code-compliant electrical services with same-day availability.
Usually on-site in 10-15 minutes for emergencies
We're not just contractors with a truck—we're your neighbors. Our office is at 350 Terry Street in downtown Longmont, which means when you call, you're talking to someone who knows the difference between Old Town wiring and Prospect new construction.
We've rewired historic homes in the Old Town Historic District, installed EV chargers in Sandstone Ranch, and upgraded panels throughout Prospect New Town. We understand Longmont's mix of 1880s Victorians, mid-century ranches, and cutting-edge zero-energy homes—and the unique electrical challenges each presents.
