Find practical answers about hiring a licensed electrician, electrical safety, project costs, permits, upgrades and how Houston Electrician Pros matches customers with independent contractors.

Safety notice: Smoke, fire, active sparking, electrical shock or an immediate threat to life or property may require emergency services. Move away from the hazard and call 911 when appropriate.

Hiring & Licensing

Are electricians in Texas required to be licensed?

Yes. In Texas, electricians and electrical contracting businesses are licensed and regulated by the Texas Department of Licensing and Regulation (TDLR). Individuals hold classifications such as Apprentice, Residential Wireman, Journeyman and Master Electrician, while businesses that offer electrical contracting services generally need a licensed Electrical Contractor with a Master Electrician of record. When you're matched through our platform, partner electrical contractors are reviewed for applicable Texas licensing before work is routed to them.

How do I verify an electrician's license in Texas?

You can look up a license holder directly on the TDLR website using their name or license number to confirm the classification, status and expiration date. A reputable contractor will readily provide their license number. We review partner licensing, insurance and coverage as part of matching, but you should always confirm the credentials of the specific contractor before signing a contract.

What is the difference between a Master Electrician and a Journeyman?

A Journeyman Electrician can perform electrical work under the general supervision of a Master Electrician. A Master Electrician has additional experience and testing, can design and plan electrical installations, and is the level of license typically required to serve as the Master Electrician of record for an electrical contracting business. For contracting work, the business itself also needs an Electrical Contractor license.

Should I hire a licensed electrician or a handyman for electrical work?

For anything beyond the most trivial task, hire a licensed electrician. Licensed electricians are trained in code, safety and permitting, and their work is far more likely to pass inspection and protect your home. Unpermitted or unqualified electrical work can create fire and shock hazards and can complicate insurance claims or a future home sale.

What questions should I ask before hiring an electrician?

Ask for their Texas license number and classification, proof of liability insurance, whether they'll pull the required permits, a written estimate with a clear scope, their warranty on labor, and an expected timeline. Confirm who will actually perform the work and that the scope matches your project. Getting more than one estimate on larger projects helps you compare fairly.

Do electricians offer free estimates?

Many electrical contractors offer free estimates for planned projects, while diagnostic or emergency visits often carry a service fee because they require on-site troubleshooting. Through our platform you can request quotes for planned projects and, where partners participate, receive up to three competitive estimates so you can compare scope and price.

Costs & Estimates

How much does an electrician cost in Houston?

Electrician pricing in the Houston area varies by the type of work and the contractor. Many charge either a flat rate per task or an hourly rate that commonly falls in the roughly $80–$150 range, sometimes with a separate service or trip fee. Small jobs like installing an outlet or switch are typically at the lower end, while panels, rewiring and service upgrades are priced as projects. The only accurate number is a written quote from the contractor you choose.

Why do electricians charge a service or trip fee?

A service or trip fee covers the electrician's time to travel to your property and diagnose the problem — the expertise required to safely find the root cause. For emergency and troubleshooting calls this fee is common; for planned installations many contractors fold it into a project quote or waive it. Ask up front how the fee is handled and whether it's applied toward the repair.

How much does it cost to replace an electrical panel?

Electrical panel replacement is a project-priced job that commonly ranges from around $1,500 to $4,000 or more in the Houston area, depending on the amperage, the condition of the service entrance, permit and inspection requirements, and whether the meter or wiring also needs work. Because the panel is the heart of your electrical system, price should be weighed alongside the contractor's licensing and reputation.

How much does it cost to rewire a house?

Whole-home rewiring is one of the larger electrical projects and is priced by the size and age of the home, accessibility of the walls, and the scope of what's replaced. Costs can range widely — often from several thousand dollars for a partial rewire to well over $10,000 for a full rewire of a larger home. A licensed contractor will inspect first and provide a detailed written estimate.

How much does it cost to install an outlet or light switch?

Adding or replacing a standard outlet or switch is usually a lower-cost task, though the final price depends on wiring access, whether a new circuit is required, and any service or trip fee. Specialty work — GFCI/AFCI protection, dedicated circuits, or adding an outlet far from the panel — costs more because of the additional materials and labor involved.

What factors affect the cost of an electrical project?

Key cost factors include the scope and complexity of the work, the age and condition of your existing wiring and panel, how accessible the work area is, the materials and fixtures selected, permit and inspection requirements, and urgency. Emergency and after-hours work typically costs more. Houston's older housing stock and coastal, storm-prone conditions can also influence what's needed.

Should I get multiple estimates for electrical work?

For larger or planned projects, yes — comparing two or three estimates helps you understand the fair scope and price and spot outliers. Make sure each quote covers the same scope so you're comparing fairly. Our platform can route planned projects to up to three eligible partners so you can compare estimates before deciding who to hire.

Panels & Upgrades

How do I know if I need an electrical panel upgrade?

Common signs include breakers that trip frequently, a panel that can't accept new circuits, reliance on multiple power strips, flickering lights when large appliances start, a fuse box or an outdated/recalled panel brand, or plans to add major loads like an EV charger, HVAC system or hot tub. A licensed electrician can assess your capacity and tell you whether an upgrade is warranted.

What is a 200-amp service upgrade and do I need one?

A 200-amp service increases the total electrical capacity coming into your home, which many modern households need to support today's appliances plus additions like EV charging or a whole-home generator. Older homes may have 100-amp or smaller service. Whether 200 amps is right depends on your current and planned load — a contractor performs a load calculation to recommend the correct size.

How long does an electrical panel replacement take?

A straightforward panel replacement is often completed in a single day, though it typically involves a temporary power shutoff and coordination with the utility, plus a permit and inspection. More complex jobs — where the service entrance, meter or wiring also need work — can take longer. Your contractor will give you a timeline as part of the estimate.

Are Federal Pacific and Zinsco panels dangerous?

Certain older panel brands, including some Federal Pacific (FPE) Stab-Lok and Zinsco panels, have a documented history of breakers that may fail to trip properly, which is a recognized fire-safety concern. If you have one of these panels, have it evaluated by a licensed electrician, who can advise whether replacement is recommended.

Safety & Emergencies

What counts as an electrical emergency?

Treat burning smells, smoke, sparks or arcing, buzzing from outlets or the panel, a panel that is hot to the touch, exposed or damaged wiring, and electrical shocks as urgent. If there is smoke, fire, active sparking, a shock or an immediate threat to life or property, move away from the hazard and call 911 when appropriate. For non-life-threatening but urgent issues, request an emergency electrician right away.

Why does my circuit breaker keep tripping?

A breaker trips to protect the circuit. Frequent tripping usually means one of three things: an overloaded circuit (too many devices drawing power), a short circuit (hot and neutral wires contacting), or a ground fault. Repeated tripping is a signal to have a licensed electrician diagnose the cause rather than simply resetting it — never bypass or defeat a breaker.

What should I do if I smell burning near an outlet or panel?

A burning or hot-plastic smell near an outlet, switch or panel is a serious warning sign of overheating that can lead to fire. Stop using the affected area, and if it's safe to do so, turn off the circuit at the breaker. If you see smoke or flames or feel there's an immediate danger, leave and call 911. Then have a licensed electrician inspect the cause before restoring power.

Why do my lights flicker or dim?

Occasional dimming when a large appliance starts can be normal, but persistent flickering across the home may indicate loose connections, an overloaded circuit, a failing panel, or a service issue. Because some causes are safety concerns, ongoing flickering is worth having a licensed electrician evaluate.

Why do I have partial power in my home?

Losing power to only some outlets or half your home — while it isn't a utility outage — often points to a specific fault, such as a tripped GFCI, a failed breaker, a loose neutral or a problem at the service. Partial power can be a sign of a connection issue that should be diagnosed promptly by a licensed electrician.

Permits & Inspections

Do I need a permit for electrical work in Houston?

Some electrical work requires a permit and inspection and some minor repairs do not — it depends on the scope of work and the local authority having jurisdiction (for work inside the city, the City of Houston Permitting Center). Panel replacements, service upgrades, new circuits and rewiring commonly require permits. The licensed contractor performing the work is typically responsible for determining and pulling the required permits unless your contract states otherwise.

Who is responsible for pulling the electrical permit?

For most projects, the licensed electrical contractor you hire is responsible for determining whether a permit is required and for pulling it, then arranging the inspection. You should receive permit information in writing when it's relevant. Be cautious of anyone who suggests skipping a required permit — unpermitted work can cause problems with inspections, insurance and resale.

Does an electrician handle the inspection too?

When a permit is required, the work is inspected by the local authority having jurisdiction, and the contractor coordinates that inspection. HoustonElectricianPros.com does not issue permits or perform inspections — permits, inspections and code approval are the responsibility of the selected electrical contractor and the applicable jurisdiction.

EV, Generators & Upgrades

How much does it cost to install a home EV charger?

Installing a Level 2 home EV charger commonly ranges from a few hundred dollars to well over a thousand, depending on the distance from your panel, whether your panel has spare capacity, the amperage of the circuit, and any permit requirements. If your panel is near capacity, a service upgrade may be recommended first. A licensed electrician sizes the circuit and installs it safely.

Can any electrician install a whole-home generator?

The electrical side of a generator — the transfer switch and connection to your home's circuits — should be handled by a licensed electrician, and larger standby units also involve gas and placement considerations. In storm-prone Houston, a properly installed transfer switch is essential. Never connect a portable generator by 'backfeeding' an outlet; it's dangerous and illegal. Ask your contractor about a safe transfer-switch setup.

Is whole-home surge protection worth it?

Whole-home surge protection installed at the panel helps shield your appliances and electronics from voltage spikes, including those from grid switching and nearby lightning — a real consideration during Houston storm season. It works alongside point-of-use surge strips for sensitive equipment. A licensed electrician can recommend the right level of protection for your home.
