Electrical contractors are essential to the design, installation, and maintenance of electrical systems in commercial, residential, and industrial settings.
Whether you’re upgrading a retail space or constructing a new office building, choosing experienced professionals matters.
If you’re looking for licensed and reliable electrical contractors in Denver, it helps to understand exactly what their work involves.
Below, we outline the main responsibilities, core services, and key benefits of working with certified electrical contractors so you can make informed decisions for your next project.
What Is an Electrical Contractor?
While the terms electrical contractor and electrician are often used interchangeably in casual conversation, they are distinct.
An electrical contractor is a trained and licensed specialist who manages every aspect of an electrical system.
They differ from electricians as they oversee teams, coordinate projects, and handle electrical planning, code compliance, and installations.
Electrical Contractor vs. Electrician (At a Glance)
- Electrical contractor: Designs and oversees projects, pulls permits, coordinates inspections, manages crews, and ensures code compliance on new builds, remodels, and complex upgrades.
- Electrician: Performs hands-on work, including wiring, fixture installations, and repairs. Ideal for smaller, single-scope jobs.
If you’re unsure which you need? A licensed contractor can help determine the right service for your project.
9 Core Services Offered by Electrical Contractors
A reputable electrical contractor provides a wide range of services tailored to each client’s needs. These include:
1) System Design and Planning
The process starts with assessing your space and power needs, followed by creating a safe electrical plan that meets industry standards and local codes.
Contractors also prepare load calculations, drawings, and permit documentation to ensure compliance with inspection requirements.
2) New Installations
Contractors manage all aspects of electrical installation in new constructions and remodels, including electrical panels, breakers, outlets, lighting, and heavy equipment connections.
Electrical contractors coordinate with general contractors and other trades to integrate the electrical system smoothly into the project.
3) Upgrades and Retrofitting
Aging electrical systems can cause outages and code violations.
Contractors upgrade these systems to meet current standards, improve safety, and support modern energy needs.
Upgrades usually involve replacing electrical panels, rewiring circuits, and enhancing capacity for high-demand appliances or EV chargers.
4) Routine Maintenance
Preventive maintenance extends the life of electrical equipment and minimizes downtime through regular inspections and repairs.
Contractors provide maintenance logs and testing reports to help business owners document compliance and identify potential issues early.
5) Emergency Repairs
Electrical issues can arise unexpectedly.
Quick-response services safely restore power and minimize operational disruptions. Experienced contractors handle urgent repairs and provide temporary power solutions until permanent fixes are in place.
6) Safety Inspections & Code Compliance
Safety checks identify hazards, confirm grounding and bonding, and ensure compliance with NEC and local standards. Contractors manage permits and inspections, providing detailed reports for recordkeeping.
7) Lighting Design & Installation
Indoor, outdoor, and parking-lot lighting projects, plus retrofits to modern LED systems for better visibility and lower energy costs.
Lighting design may also include photometric planning to ensure brightness levels comply with local codes and client requirements.
8) Energy-Saving Upgrades
LED conversions, smart controls, and panel or circuit additions for high-demand loads such as HVAC systems, appliances, or EV chargers.
Contractors may also recommend system monitoring or submetering to track energy use and reduce long-term operating costs.
9) General Repairs & Troubleshooting
Flickering lights, tripped breakers, warm outlets, or unexpected shutdowns are all diagnosed and safely fixed by qualified technicians.
Troubleshooting services often involve advanced testing tools and thermal imaging to detect underlying faults before they become serious issues.
