What Counts as Low Voltage Wiring?
Low voltage covers electrical systems running at 50 volts or less — everything that carries data, video, audio, and signal rather than building power. In a typical Chicago commercial space that means network and data cabling, security camera wiring, access control and door wiring, intercom lines, WiFi access point drops, speaker and PA wiring, TV and AV cabling, and phone system wiring. Your electrician handles the panels and outlets; we handle everything that makes the building smart, connected, and secure.

Code-Compliant, Inspection-Ready Work
Chicago inspectors care about low voltage more than most cities: plenum-rated cable in air-handling spaces, fire-stopping at rated wall penetrations, proper supports (no cable resting on ceiling grid), and conduit where the building demands it. Every Windy City Voltage install follows NEC Article 725/800 practices and City of Chicago requirements — and we hand over labeled, tested, documented work your inspector and IT team will sign off on.

Why Hire a Low Voltage Specialist Instead of an Electrician?
Licensed electricians are essential for power — but data and signal wiring is a different trade. Termination quality, cable categories, bend radius, separation from power lines, and testing/certification determine whether your systems run at spec or limp along. We test and certify every run. When a business searches for "low voltage wiring contractors" after an electrician's Cat6 fails certification, we're usually the second call — be smart and make us the first.

Frequently Asked Questions — Low Voltage Wiring in Chicago
Do you work with general contractors on buildouts?
Yes — a large share of our work is as the low voltage sub on commercial buildouts. We provide drawings, coordinate rough-in with framing and electrical schedules, and deliver closeout documentation for the project file.
What does low voltage wiring cost?
Most commercial work is priced per drop or per device: standard Cat6 drops typically run $150–$350 each depending on distance and construction; device wiring (cameras, readers, APs) similar. Larger projects are quoted as a fixed scope after a free walkthrough.
Can you wire through finished walls without destroying them?
Yes. Retrofit fishing is a core skill — we use existing pathways, minimal openings, and clean patch-ready cuts when openings are unavoidable. Occupied-space work is scheduled to keep your business running.
Do you remove old abandoned cable?
Yes. Code requires abandoned plenum cable to be removed, and clearing decades of dead wire is often the first step of a clean upgrade. We include removal scope in upgrade quotes.
