Types of Services Offered by Electricians

Electricians offer a range of services to tackle electrical problems. The following are some of their most frequently requested services for residences.

Electrical System Installation

Installing electrical systems involves careful planning, wiring, and connecting various components to ensure safe and efficient electricity flow. It begins with assessing your home’s energy usage and needs and selecting appropriate cables, conduits, and light fixtures. Finally, they connect the main electrical panel, distribute circuits to the outlets and fixtures, ground the system for safety, and integrate protective devices, such as circuit breakers.


Maintaining your home's safety hinges on repairing electrical problems, such as faulty wiring, as soon as possible. A skilled electrician can diagnose the problem and root cause and repair it.

Whole-House Rewiring and Panel Upgrades

Older houses may require whole-home rewiring and panel updates, which involves replacing the faulty electrical system in your home. Electricians inspect existing wiring, look for potential hazards, and create a strategic plan. Based on their findings, they take out old wiring, install new cables, and update outlets, switches, electrical panels, and fixtures to comply with up-to-date building codes and safety standards.

Surge Protection

Getting professional surge protection ensures your expensive devices are protected from damage induced by power surges. Electricians will evaluate your needs and set up surge protectors, which redirect excess electricity from electronics when there are spikes and surges. Professional surge protection installation at strategic points, like at individual outlets or the main electrical panel, will protect against power surges and lessen the risk of expensive damage.

Emergency Electrical Services

Emergency electrical services supply crucial help. These 24/7 services offer a fast fix for the issue. Professional services for emergencies tackle electrical fires, power outages, damage from weather, and faulty wiring. Professional services provide peace of mind and a quick resolution.

Factors To Consider When Choosing an Electrician in Gaithersburg

The following are a few key factors to consider when choosing an electrician in Gaithersburg.

  • Cost: Choose an electrician who's open about their pricing. Compare quotes from multiple contractors to find one that fits your budget.
  • References: Request references, so you can get direct feedback about the electrician's work.
  • Reputation and reviews: Read through sites such as the Better Business Bureau and Google Reviews to learn about other customers’ experiences. Look for a licensed electrician with a reputation for good customer service.
  • Safety measures: Choose an electrician who prioritizes safety and takes necessary precautions to prevent accidents and injuries. Ask for information on their safety program and ensure they use proper gear. If you notice an electrician working too quickly or sloppily, you may want to cancel service and find another technician.
  • Qualifications: Look for a licensed electrician who's qualified to perform electrical work in Maryland. The Maryland State Board of Master Electricians has more information on the requirements for electricians in the state.

How Much Does an Electrician Cost?

Electricians may charge a fixed price or an hourly rate. Most electricians charge $48–$72 an hour in Gaithersburg, which adds up to $180–$360 for most small to medium tasks. Discuss the project in detail with the electrician for the most accurate price.

Frequently Asked Questions About Electrical in Gaithersburg

What should I do in case of an electrical emergency?

In case of an electrical emergency, put safety first. First, switch off the power supply to the affected area if possible. Then, reach out to a professional electrician to evaluate the situation and have it repaired.

How often should I have my electrical system inspected?

Have an electrical inspection professionally done every 3–5 years at the minimum. You may need more frequent inspections if you have recurring issues such as flickering lights or tripped breakers, as these may indicate old wiring, overburdened circuits, or other deficiencies.

What causes circuit breakers to trip repeatedly?

Circuit breakers trip repeatedly for various reasons including overloaded circuits, an old breaker that needs replacement, or outdated wiring. Overloaded circuits happen when too many devices are using electricity, causing the circuit breaker to shut off to prevent the circuit from overheating.

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

Prevent electrical fires by having a licensed electrician routinely inspect your home's wiring, promptly addressing any identified hazards, and installing quality surge protectors. Also don't overload your circuits and ensure all electrical work meets local building codes. Taking these safety precautions can greatly lower electrical risks.

How can I make my electrical system more energy efficient?

You can improve your electrical system through energy-efficient upgrades such as smart thermostats and LED lighting. Additionally, consider Energy Star-certified appliances, which use less electricity. You can also install solar panels, which can help cut your carbon footprint by up to 10 pounds cut annually.
