Common Questions

Do you work with general contractors on build-outs?

Yes. Build-outs and remodels usually run on a general contractor's schedule, and we work alongside GCs on commercial projects across St. Charles County. We coordinate with the other trades on site, show up when we say we will, and keep our punch-list items moving so your close-out date holds.

Can you schedule work outside business hours?

Yes. Offices and retail spaces cannot always host electrical work during business hours, so we schedule build-outs, lighting upgrades, and repairs for early mornings, evenings, and weekends when it works for your building.

Do you offer free estimates for commercial work?

Yes. We offer free estimates throughout St. Charles County.

Can you set up a maintenance schedule for parking lot and exterior lighting?

Yes. We repair and upgrade pole fixtures, photocells, and controls, and we can set up a maintenance schedule so burned-out heads get replaced fast.
