Premier Commercial Lighting Services

Your company’s lighting choices can have a significant impact on your employees’ productivity and your customers’ experience. Fortunately, you don’t have to sort through the variety of lighting types, colors, and intensities on your own. Our commercial electrical contractors can provide a lighting analysis and help you decide on the best lighting for your company’s needs.


Our commercial lighting installation services include parking lot, security, and safety lighting, as well as practical and design lighting solutions. Before starting the installation process, we’ll inspect your current electrical system and ensure it can handle new lighting. If you experience any issues with your lights down the road, our commercial lighting services also include timely repairs so that you can keep your business running.

Effective & Reliable Commercial Wiring Services

When you hire us for commercial electrical services, you can expect our electricians to provide expert advice on the best layout and quality installation of new wiring and rewiring solutions to suit the specific needs of your business and industry. All our professionals know how to use and read blueprints and can safely troubleshoot problems with circuits, switch gears, controls, and lighting systems.


If you notice wiring issues, such as electrical sparks, heat or smoke coming from your outlets or fixtures, or circuit breakers frequently tripping, it’s time to schedule commercial wiring services. We’ll closely inspect your electrical system to detect the root cause of the problem and then perform quick and effective repairs. We can also provide electrical panel and wiring services as part of a renovation or new construction project. No matter the size of your project, our commercial electricians are equipped to handle it.

Dependable Commercial Surge Protection Services

Plug-in surge protectors can only do so much to protect your devices from high power voltages. It only takes one thunderstorm or utility disturbance to result in extensive damages that require costly commercial electrical services. Instead of relying on power strips, protect your devices and equipment with commercial surge protectors.

Our commercial surge protection services can help reduce the chance of damage to your systems and data records by protecting them against power surges. With our commercial surge protection solutions, the moment an irregularity in the power supply is detected, the surge protector shuts the power off, so all your equipment and wiring are protected.

Professional Services For Phone, Cable, & Data Systems

Our commercial electricians will expertly install all your communication wiring for telephone, cable, and data services. We can install additional sockets or move them to more convenient locations.

Commercial Backup Power Generator Installations

If your business experienced a power outage today, would it be able to remain productive, or will things come to a screeching halt? Installing a commercial generator can ensure your business has efficient power to keep equipment operating, devices connected to the internet, and security systems functioning. When the main power goes out, your generator will auto-start, providing you with a seamless transition to backup power. Once the utility supply is restored, it will switch off without you needing to lift a finger.


When you hire our technicians for commercial electrical services, you can trust we will consult with you on generators that suit your commercial capacities. We will also ensure you have the power you need to keep your communication, data, and security systems, refrigeration, production line, medical equipment, and the rest of your essential services operating.


The next time a storm blows through town or an accident occurs, you will not have to worry about gaps in your productivity. You can rely on your commercial backup power generator installation to rise to the challenge when you need it most.
