COMMERCIAL ELECTRICAL COMPANY

Commercial Electricians in Lisle, IL

If you run a business in Lisle, you already know that the electrical system is one of those things nobody thinks about until it stops working. Then it’s everything. Cob Services is a licensed commercial electrical company serving Lisle and the rest of DuPage County, and we have spent more than 15 years wiring, upgrading, and troubleshooting the kind of buildings that keep this town running: restaurants, offices, retail, warehouses, and multi-unit properties.

We work the way a good general contractor wants an electrician to work. We show up when we say we will, we pull the right permits, and we build to current Lisle and DuPage County code so your inspection passes the first time. Most of our work comes from owners and GCs who hired us once and kept our number. If you want to see the kind of jobs we take on, our recent-projects page is worth a look before you call.

Call (630) 427-5923 or request service to talk to a licensed commercial electrician in Lisle today.

Local Commercial Electricians in Lisle, IL You Can Actually Reach

There is a difference between a national booking service that subcontracts your job out and a local commercial electrician who picks up the phone. We are the second kind. When you call Cob Services, you reach the people who do the work, and that matters when a deadline is moving or an inspector flags something the morning of your opening.

Commercial work is its own discipline. Three-phase power, higher loads, tenant build-outs, code requirements that change depending on occupancy type — none of that is the same as wiring a house. Our commercial electricians do this every day, so we can give you a straight answer on scope, timeline, and cost instead of guessing. For a Lisle business, on time and on budget is not a nice-to-have. It is the whole job.

Commercial Electrical Services in Lisle, IL

We handle the full range of commercial electrical services for businesses across Lisle, from a single failing circuit to a ground-up build. Here is what we get called for most.

Commercial Electrical Panel Upgrades in Lisle, IL

Older buildings and growing businesses outgrow their panels. We size and install commercial electrical panel upgrades that give you the capacity you need today and room for what you add next year, with breaker replacements, sub-panels, and dedicated circuits done to code.

Commercial EV Charger Installation in Lisle, IL

More Lisle businesses are adding chargers for staff, tenants, and customers. We are commercial EV charging station contractors who handle the whole job: load calculation, panel capacity, conduit, and the charger itself. Whether you need one Level 2 unit or a row of stations for a parking lot, our commercial EV charging station installation work is built to handle the draw without tripping the rest of your building.

Commercial Electrical Wiring & Rewiring in Lisle, IL

New construction, tenant build-outs, and aging buildings all need someone who can run wire correctly the first time. Our commercial electrical wiring and rewiring covers everything from a full rewire of an older property to clean new circuits for an expansion, including aluminum wiring remediation when we find it.

Commercial Electrical Repair Services in Lisle, IL

When something stops working, you want a diagnosis, not a guess. Our commercial electrical repair services cover dead circuits, failing breakers, flickering or dropped power, faulty outlets, and the strange intermittent problems that other electricians give up on. We find the cause and fix it.

Commercial Emergency Electricians in Lisle, IL

Power problems do not wait for business hours. Our commercial emergency electricians respond when a safety issue or an outage threatens to shut you down, so you can get back open instead of sending staff and customers home.

Commercial Wiring Services & Remodeling Electricians in Lisle, IL

Renovating or reconfiguring your space? Our commercial remodeling and renovation electricians work alongside your GC on layout changes, added circuits, lighting redesign, and data cabling, so the electrical keeps pace with the rest of the build instead of holding it up.

 Trustindex verifies that the original source of the review is Google. I recently hired this company for a full electrical rewire of my home, as well as the installation of a Tesla charger, and the experience was excellent from start to finish. Their pricing was fair and transparent, with no surprises along the way. The team was professional, knowledgeable, and clearly experienced in both residential electrical work and EV charger installations. What stood out most was their reliability — the project was completed on schedule, and the quality of work met high standards. They communicated clearly throughout the process and made sure everything was done safely and correctly. I would highly recommend them to anyone looking for dependable electrical services, whether for a full home rewire or EV charger installation.
