Types of Services Offered by Electricians

Electricians provide services that cover a variety of electrical problems. These are some of the home services they provide.

Electrical System Installation

Most electricians set up electrical systems, which involves careful planning, wiring, and joining various components. First, the contractor evaluates your home's electricity usage and requirements. Then they will plan the wiring and choose appropriate cables, conduits, and light fixtures. Finally, they connect the main electrical panel, distribute circuits to individual outlets and fixtures, ground the system, and integrate protective devices, such as circuit breakers.


Maintaining your home's safety relies on addressing electrical problems, such as faulty wiring, promptly. Skilled electricians can repair any problems with your system. They have experience troubleshooting complex systems, safely replacing damaged components, and restoring functionality.

Whole-House Rewiring and Panel Upgrades

Whole-home electrical rewiring and panel upgrades involves replacing old wiring and panels throughout your whole house. This is typically necessary for aging homes with systems that may present potential hazards or don't adequately meet modern electrical demands. The process involves the electrician examining the wiring for potential risks, mapping out the project, and removing the old cables. Then, they install new wires, outlets, panels, fixtures, and switches that adhere to current building codes and safety standards.

Surge Protection

Professional surge protection defends your electrical system and valuable devices from the damaging effects of power surges. Electricians will appraise your needs and install surge protection devices. These devices serve as barriers, redirecting excess energy from sensitive equipment during power surges. Professionally setting up surge protection devices at key points, such as at the main electrical panel or individual outlets, will protect your devices against power surges and lessen the risk of heavy damage.

Emergency Electrical Services

Emergency electrical services are vital when you have sudden breakdowns, hazards, or disruptions. They're available 24 hours a day to get your electricity running again. Electricians tackle electrical emergencies such as power losses, fires, weather destruction, and damaged or hazardous wiring safely and promptly.

Factors To Consider When Choosing an Electrician in Knoxville

Consider the following factors when choosing an electrician in Knoxville.

  • Cost: Choose an electrician who's transparent about their pricing. Compare quotes from multiple contractors to find one that fits your budget.
  • References: Request references from past clients. Get in touch with these references to discuss their experience working with the electrician.
  • Reputation and reviews: Checking feedback on sites such as Google Reviews and the Better Business Bureau can offer you some insight into the service provider's work standards and customer service.
  • Safety measures: Your electrician should adhere to proper safety precautions to prevent accidents and injuries. Ask about their safety protocols, such as wearing the proper gear.
  • Qualifications: Electricians in Tennessee must have a license. Local municipalities regulate journeyman and master electrician licenses, while electrical contractor licenses are issued through the Tennessee Board for Licensing Contractors.

How Much Does an Electrician Cost?

Several factors influence the cost of hiring an electrician, including the electrician’s experience and qualifications, your location, the project’s complexity, and the specific services required. Most electricians in Knoxville charge $31–$47 by the hour, but some may charge a fixed price. It can add up to $120–$240 for most small to medium tasks. It’s important to get multiple quotes and discuss project details for the most accurate price.

Frequently Asked Questions About Electrical in Knoxville

What should I do in case of an electrical emergency?

Safety should be your first priority if an electrical emergency occurs in your Knoxville home. Don't go near sparking wires and shut off the power at the main breaker panel. Seek a safe spot and call 911 if necessary. You can also call an emergency electrician for quick help pinpointing the cause and handling the issue safely.

How can I tell if my home's electrical system needs an upgrade?

Some warning signs your electrical system needs updating may include outdated wiring, burning smells from outlets, outlets not working, frequent tripped circuit breakers, flickering or dimming lights, or using fuse boxes instead of circuit breakers. If your home was built more than 30 years ago—which many homes in Knoxville are—and hasn't had an upgrade, it likely needs system improvements to increase efficiency, safety, and capacity to handle modern electrical demands.

What causes circuit breakers to trip repeatedly?

Circuit breakers usually trip due to various reasons including an old breaker that needs replacement, overloaded circuits, or outdated wiring. Circuits become overloaded when too many appliances are plugged in, triggering the circuit breaker to trip to prevent hazards such as fires.

How can I reduce the risk of electrical fires in my home?

Prevent electrical fires by having routine inspections of your home's wiring, addressing issues quickly, and using quality surge protectors. Also ensure circuits aren't overloaded, electrical appliances and tools are UL certified, and all electrical work meets local building codes. Taking these safety precautions can greatly lower electrical risks.

Can electricians help with energy-efficient upgrades?

We recommend contacting an electrician for energy-efficient improvements to your electrical system. An electrician can identify beneficial upgrades, such as smart-home devices, programmable thermostats, and energy-saving electrical systems.
