From installing a ceiling fan to complete rewiring, no job is too big or too small for the Althoff team. In business for over 60 years, we’re the company you can trust for safe, efficient, expert electrical services.

Althoff’s residential electricians serve the Greater Chicago area, including the northwest suburbs.

Electrical Repair

Circuit breakers keep tripping? Lights flickering? Faulty wiring? Electrical problems are not something to ignore. Putting off electrical repairs can cause inefficiencies in energy use or even increase your risk of electrical fires—one of the most common causes of house fires nationwide.

Your best move is to get in an electrician who can diagnose the problem correctly and get it fixed right the first time. Our licensed, bonded and insured team of electricians will get it done, satisfaction guaranteed.

24/7 Emergency Electricians in Chicago and the Northwest Suburbs

Some electrical problems, like a loss of power or smoking or sparking wires, just can’t wait. Our 24/7/365 emergency electrical services help get your home life back to normal safely. We have two Chicago area locations to provide fast, friendly service.

Not sure if your electrical problem is an emergency? Play it safe and give us a call anyway. There’s no charge for the call.

Electrical Installations, Upgrades & Replacements

Due to the complexity and safety concerns, most electrical installations are not a DIY job. Many homeowners also prefer to leave even relatively simple installations, like ceiling fans and CO/smoke detectors, to the experts for safety reasons.

There’s no electrical installation job, big or small, that you can’t hand off to Althoff. We’ll make sure your electrical installation is done safely, correctly, and according to code. Our electricians have decades of experience in installing, upgrading and replacing electrical fixtures, wires and panels.
