Commercial Specialty Lighting

Specialty commercial lighting options usually serve a specific function. For example, certain lamps may be used to develop photography or sterilize medical equipment. These specialized lighting solutions often require specific electrical services, which we can provide.

Commercial Electrical Safety

By maintaining and updating your circuit boards and wiring, we can increase the safety of your electricity.

In severe circumstances, they can even lead to electrical fires. Let our technicians ensure the integrity of your electric system with regular and consistent inspections!

Commercial Electrical Security Installations

Many commercial buildings rely on security systems to deter and help prevent crime. Even an empty commercial building is vulnerable to theft and property destruction. Don’t panic! We can:

  • Secure the doors and windows of your facility with an alarm system
  • Hard-wire a security system directly into your electrical system
  • Install a CCTV video surveillance camera and wire a monitoring station

Why Professional Electrical Work Matters to Your Commercial Business

Electricity disruptions and expenses can severely hamper the operations of any commercial property. Regardless of your industry, a safe and reliable electrical system is pivotal. Taking shortcuts or leaving compromised or faulty electrical issues unattended is risky. At the same time, having an amateur perform electrical work can be hazardous. Improper electrical work can nullify insurance coverage, violate national and local electrical codes, and even spark structural fires. By hiring our trusted and professional technicians, you can avoid these scenarios.

Benefits of Hiring a High-Quality Electrician for Commercial Electrical Work

Our top-notch electrical work will give you the peace of mind you deserve. We will make sure your business satisfies local electrical codes by being safely and properly wired.


Our electricians wear flame-resistant clothing and personal protective equipment (PPE) for added safety. We also arrive with all the essential tools, including:

  • Approved volt detectors/indicators
  • Insulated screwdrivers
  • Side cutters
  • Wire strippers
  • Electrical wall chasers
  • Electrical tape

Our commitment to never cutting corners or rushing a job is as important as the equipment we show up with. We fully inspect all electrical components, power cords, and cables before performing any electrical service.


Our team of certified electricians never stops learning – even after they put on the uniform. From continuing education courses to seasonal seminars, they consistently undergo rigorous training to stay up to date. Servicing all kinds of industries and facilities, our electricians are committed to constantly growing and evolving. Given our years of experience handling cabling, lighting, and wiring electrical services for offices, hotels, hospitals, schools, and other venues, our expertise cannot be beaten.


Becoming a certified electrician takes years. At the very minimum, our electricians graduate from courses that take months to complete. After learning the ins and outs of the trade in the classroom, they must then shadow a licensed professional for four years of on-the-job training. This experience is integral – electrical systems are complicated, dangerous, and require seasoned specialists backed by years of expertise.


With professional electricians, mistakes and errors are extremely rare. However, electrical work is complex and unfortunate situations can happen. In the rare case that a problem materializes, Mister Sparky® insures all our electricians to cover claims concerning bodily injury or property damage sustained during electrical work.

Quality Work Done Right the First Time

We always strive to get the job done right in one go! That is why our electricians follow expert techniques and protocols to optimize electrical durability. Following the highest industry standards, our electrical repairs, installations, and upgrades strictly adhere to the best industry practices around.

Knowledge and Adherence to Regulations and Code

We adhere to all electrical codes and regulations prescribed by federal, state, and municipal ordinances to ensure your property will be covered by insurance and pass electrical inspections if you ever want to sell. We are also familiar with safety code compliance regulations pertaining to fire alarms, smoke alarms, CO2 detectors, and CO alarms.


We understand your time is valuable and waiting around for a late electrician is inexcusable. That's why we guarantee to arrive on time. Our promise is simple: “We're On Time, You'll See, Or The Repair Is Free!”™. That’s why we’re known as America's On-Time Electrician®!

Peace of Mind

All Mister Sparky® contractors agree to display the U-Win seal, which backs our electrical services with a 100% satisfaction guarantee for two years. By reaching out to U-Win, customers can receive detailed warranty tips and resolution assistance. Every one of our locations also adheres to our drug-free workplace and formal drug testing mandates.

Commercial Buildings We Provide Electrical Services For

Our electricians have the flexibility to work in every kind of commercial facility and industry. Fully equipped with trusted tools and techniques, we can improve all types of electrical setups.

Restaurants, Bars, and Other Eateries - Restaurants rely on multiple specialized pieces of equipment that must function safely and efficiently. When called upon to service walk-in coolers, freezers, grills, and hood vents, our electricians will ensure all electrical components are robustly installed and well-maintained. We can also install lighting arrangements that will be sure to make a decorative splash.

Motels, Hotels, and Resorts - Hotels have uniquely complicated electrical demands. Whether your establishment is a few bungalows or 20-stories tall, we have the training and technologies to complete electrical renovations, low-/high-voltage installations, and emergency circuitry repairs quickly.

Business Offices - If your office needs quality electrical service, we are the go-to solution. Our electrical specialists can handle everything from LED lighting installations to circuit panel replacements to automating your electrical system. If you are thinking of retrofitting your commercial lighting to reduce energy costs or your carbon footprint, we can deliver promising and impactful results.

Assisted Living and Nursing Homes - Our electricians have been thoroughly trained to work with commercial buildings that house multiple tenants. Senior care facilities and nursing homes are extremely dependent on electricity. Many elderly patients rely on the life-saving assistance of electrical medical equipment. Our trusted technicians can ensure your equipment is backed up with generators and protected electrical supply units. They can also install fire alarm and security systems, surge protectors, intercom units, and retrofit electrical circuits to help prevent future disasters from happening.

Sports Arenas & Venues -Entertainment venues and stadiums use a high volume of electricity to energize:

  • Booming sound systems
  • Luminescent luxury boxes
  • Flashing video screens
  • Mammoth floodlights
  • Myriad food stands
  • Expansive air conditioning needs

These electrical components require regular maintenance. Our electricians can routinely inspect your wiring and circuit breakers to ensure they are in prime condition to handle electrical demands at 100% capacity. We are also available to regularly maintain your outlets, cables, displays, wiring, and lighting.

Malls & Shopping Centers - When it comes to lighting parking lots, illuminating individual stores, wiring HVAC systems and security alarms, and providing backup electricity for large shopping centers, a certified commercial electrician is essential. A minor power disruption can compromise the safety of thousands of customers and cause considerable losses in revenue. Be proactive and contact Mister Sparky® as soon as possible to make sure your electrical system is well-maintained!

Food Retailers & Grocery Stores -Grocery stores and supermarkets depend on massive electrical systems. Our electricians can perform:

  • Service panel & backup power distribution
  • Network cabling
  • Fire alarm electrical service
  • Mechanical, refrigeration, appliance, HVAC, BMS, AV, and security system wiring
  • Interior and exterior lighting installations
  • Repairing and installing lighting control systems

Convenience Stores & Gas Stations -Gas stations and convenience stores have many opportunities to decrease energy consumption. With lighting, refrigeration, and HVAC systems running nonstop, utility bills are often very high. Long operating hours also add stress to these electrical systems, consequently requiring frequent maintenance or even full replacement. Unfortunately, saving energy by cutting back on usage isn't viable–lights, freezers, and HVAC units are necessary during business hours. One electrical solution we can install is an anti-sweat heat (ASH) controller. This can be applied to refrigerated display cases to prevent fogging, condensation, and energy loss.

Schools, Colleges & Universities - Educational facilities and large campuses can have jaw-dropping utility bills. We can help. By installing electrical timers and controls, retrofitting lighting fixtures with LED options, and modernizing HVAC systems with high-efficiency materials and sensors, we can help you save thousands by smartly mitigating electricity usage.

Public Buildings & Airports - Municipal buildings and airports require a high level of electrical backing to sustain power supply during power outages and electrical emergencies. We can install backup generators and upgrade electrical control panels to help safeguard against unexpected events. When it comes to skyscrapers and airports, we can also supplement indoor lighting with occupancy sensors and timers to save electricity during off-peak hours when foot traffic is nonexistent or minimal.

How Much Does It Cost to Hire an Electrician for a Commercial Property?

More than anything, the price of commercial electrical work depends on the size of the task at hand. Other factors that will affect the final cost include:

  • Hours & complexity of labor
  • Materials required
  • Distance to the worksite
  • Inspection & permit fees

Regardless of the scope and specifics of the electrical work, we will go above and beyond to offer fair, competitive, straightforward prices that are free of hidden fees or surprises.
