Commercial electrical projects need clear communication from the start. Here is how we move from first contact to finished work.
We discuss your project scope, timeline, and any specific code or permitting considerations. You get a clear picture of what the work involves before anything begins.
One of our licensed electricians visits your location to evaluate existing systems, identify any issues, and confirm what the project requires.
We provide a written scope of work so you know exactly what is planned. No vague estimates or surprise changes mid-project.
We coordinate the work around your business operations as much as possible, keeping disruption to a minimum while meeting code and safety requirements.
Before we close out the job, we walk through the completed work with you, answer questions, and confirm everything meets the agreed scope and local code standards.
Find clear answers about service options, scheduling, preparation, and what to expect before you request an estimate.
Q1
We work on offices, retail spaces, restaurants, warehouses, and other commercial facilities across Columbia, Lexington, Irmo, Chapin, and West Columbia. If you are unsure whether your project fits, call us and we can talk through it.
Q2
Yes. Permitted work is required for most commercial electrical projects in South Carolina. We handle the permitting process so the work is code-compliant and your business is protected.
Q3
We do our best to schedule work in a way that minimizes disruption to your operations. This is something we discuss during the planning phase so everyone is on the same page before work starts.
Q4
Common signs include breakers that trip frequently, limited capacity for new equipment, outdated panels from older construction, or failing a commercial inspection. An on-site assessment from one of our electricians can give you a clear answer.
Q5
Yes. We install EV charging stations for commercial parking areas, including the panel work and wiring needed to support the load. This is a growing request from businesses in Columbia and the surrounding area.
Q6
Commercial generator installation includes sizing the unit for your load requirements, running the necessary wiring, installing a transfer switch, and connecting to your panel. We handle the full scope and ensure the system meets local code.
Q7
Yes. Older commercial buildings often have outdated wiring, overloaded circuits, or undocumented modifications. Our electricians diagnose the problem systematically before recommending repairs, so you are not paying to fix the wrong thing.
Q8
Call us at (803) 784-8386 or email Andrew.craig@overwatchelectric.com. We will set up a time to discuss your project and, when needed, schedule an on-site visit to put together an accurate proposal.
