Commercial Electricians

Where Business Operations Meet Reliable Electrical Power

Your commercial property’s electrical system is the backbone of your daily operations. When it functions correctly, you don’t think about it. When it fails, your business suffers — lost revenue, frustrated customers, interrupted service, and potentially unsafe conditions for employees and visitors. Fowles Electric provides expert electrical solutions for retail stores, office buildings, medical facilities, restaurants, warehouses, and multi-tenant commercial properties throughout the Inland Empire. As experienced commercial electricians, we understand that every hour without full electrical function costs you real money. That’s why we prioritize clear communication, efficient work practices, and minimal disruption to your business operations while delivering the same code-compliant, safety-focused installations that have earned our reputation.

Commercial electrical work differs from residential in almost every way — voltage levels, equipment types, code requirements, and the simple fact that you can’t just “work around” a business that needs to stay open. Our team of skilled electricians commercial specialists arrives with the training and equipment needed for commercial environments. We work with three-phase power systems, commercial lighting controls, emergency egress lighting, fire alarm integrations, and specialized equipment connections that don’t exist in homes. We’re also experienced at working around your schedule — nights, weekends, or during planned closures — so your customers and employees never experience unnecessary disruption. From small retail boutiques to large shopping centers, we adapt our approach to fit your specific business needs.

Why Choose Us

Commercial property owners and facility managers have many options for electrical services, but few deliver the combination of technical expertise, business awareness, and genuine customer care that Fowles Electric provides. We’re large enough to handle complex commercial projects — multiple crews, after-hours availability, full permitting and inspection coordination — but small enough that every client gets personalized attention from an owner who cares about their success. Our commercial electricians are trained in OSHA workplace safety, lockout/tagout procedures, and the specific codes that apply to commercial occupancies. We carry full liability insurance, workers’ compensation, and a state electrical contractor license. When you hire Fowles Electric, you’re hiring a partner who treats your business’s uptime as seriously as you do.

Dennis helped me add some dedicated circuits to my kitchen and laundry room. He found a solution to a wiring problem that an earlier electrician had missed. Consequently, Dennis was able to do more for me, in less time, and for notably less money and complications than the earlier quote. He was quick, professional, friendly and very fair and transparent. You never feel like you're being 'sold' anything. Fowles will be my first call, next time. I highly recommend.

Fowles Electric Inc. is a life saver. We had an outlet spark out and Dennis found the outlet was still hot which could have caused a catastrophic event. Dennis and Brice were extremely professional, courteous and were very respectful of our property. They went above and beyond with taking an extra trip to the hardware store to obtain additional products to replace light switches. I highly recommend Fowles Electric Inc.!

Needed someone to install a brand new Tesla wall charger in my home. They were very quick with the installation appointment and was able to accommodate my days and times I was available. Installation did not take all day and the price was affordable. Have recommended them to my friends that have EV and needed chargers installed. Would def use them again in the future for any electrical work needed.
