STS Electric is a licensed Chicago electrical contractor serving homes, condos, restaurants, and light commercial sites across the Northwest Side, Downtown, and Cook County suburbs. We dispatch from 939 W North Ave #746, Chicago, IL 60642. Call (773) 721-1111 for inspections, upgrades, and 24/7 emergencies. This page explains why we work the way we do: safety first, clear scopes, correct permits, and workmanship that holds up under Chicago inspection.
Who STS Electric Is
Since 1980 we have focused on full-service electrical work for private and commercial properties in Chicago and nearby suburbs. Jobs range from a single GFCI replacement to service upgrades, tenant build-outs, EV garage feeds, and storm-related outages. No job is too small when the hazard is real, and no job is too large when the scope is documented and permitted.
We maintain an A+ Better Business Bureau rating, offer competitive pricing, and extend discounts for seniors and military customers. Satisfaction means the circuit works, the panel is labeled, and the customer knows what was done and why.
Mission
Our mission is to deliver accurate, reliable electrical service for residential, commercial, and light industrial clients that meets current Chicago and Illinois standards. Safety for crews and customers sits ahead of speed. Old-fashioned work ethics still apply: show up when promised, communicate clearly, and leave the site cleaner than we found it.
Every electrician we send is trained, experienced, licensed, insured, and bonded for the work assigned. Materials match the job. Temporary fixes that hide a fire risk are not part of our process.
Vision
Our vision is to be the Chicago electrician homeowners and property managers recommend because the work is safe, on time, and within the agreed budget. We want customers to feel confident that we finish the task, pull the right permits, and explain options in plain language.
We grow by staying faithful to those standards, learning new technology as code and equipment change, and assigning the right technician for the specification. High-quality products at fair prices, proper tools, and the right safety gear are non-negotiable on every site.
Core Values We Hire and Fire By
We are locally owned and based in the neighborhoods we serve. Values are not a poster on a wall. They are how we decide who gets the truck keys.
Safety first means lockout/tagout, PPE, and stopping work when conditions are unsafe. Expertise and precision mean load calculations, labeled panels, and code-correct installs. Courtesy and clear communication mean written scopes, honest timelines, and no surprise invoices for work that was never discussed.
Honesty, loyalty, integrity, ownership, and accountability cover callbacks and warranty follow-through. Continuous education keeps crews current on AFCI/GFCI rules, EV charging, and Chicago Department of Buildings expectations. Quality performance means organized crews and problem-solving on imperfect older buildings, not blame when a bungalow surprises us.
How This Shows Up on Real Chicago Jobs
On a bungalow panel upgrade we size the service for future loads, not only today’s microwave and furnace. On a restaurant cooler trip we make the scene safe first, then schedule permanent repair. On a condo EV install we handle association COI and meter-room access before equipment arrives.
That is the difference between marketing copy and field practice. For how to evaluate any Chicago contractor, see our hiring checklist. For residential scope and scheduling, see licensed residential electrician services.
Licensing, Insurance, and Local Accountability
Chicago electrical work that fails inspection costs time and money. We pull City of Chicago or village permits when required, document load calculations when capacity is tight, and leave labeled panels so the next buyer or inspector can read the history. Why licensing matters in this market: why licensed electrical services matter in Chicago.
Commercial property managers can review broader tenant and facility scope on our commercial electrical services. For a wider comparison of Chicago electrical options, see the Chicago electrician guide.
