Our teams are known for showing up when scheduled, working efficiently, keeping job sites clean, and communicating clearly throughout the project. We operate with organized systems that reduce mistakes, speed up timelines, and help general contractors avoid delays, rework, and coordination headaches.
While our primary focus is new construction and multi-family projects, we do work with homeowners for specific services such as EV chargers, service upgrades, panel swaps, and other professional-grade electrical installations.

Yes. Wires R Us has been serving the Black Hills since 1999 and is now a second-generation electrical contractor. Our work is fully licensed, code-compliant, and built to pass inspections without surprises. We regularly work across Rapid City, Spearfish, Sturgis, Belle Fourche, Hot Springs, Hermosa, Black Hawk, and surrounding communities.
Reliability is one of our core values. We schedule realistically, communicate proactively, and follow through on commitments. General contractors continue working with us long-term because we keep projects moving, coordinate well with other trades, and eliminate the common frustrations that come with unreliable subcontractors.
In the tract home builder world, demand is high. Standards are extremely high and scheduled are locked in. We work….
We choose products for long-term performance and low callbacks. In practice, that means we install brands that have shown consistent build quality, low failure rates, and good field support. For example, we prefer RAB, Maxim, and Cooper for lighting, Schneider Electric for panelboards and breakers, King Wire for SER service entrance cable, and Briggs & Stratton for standby generators because of their track records. Choosing reliable brands, installing them correctly, and inspecting connections during installation are the largest factors in long-term reliability.
