Residential Electrician Services in Houston, TX

Electrical Masters Company provides licensed, bonded, and insured residential electrical service for Houston homeowners — whole-home standby generators, EV charger installation, electrical panel and breaker upgrades, rewiring, lighting, and safety inspections. Our master electricians pull the proper permits, work clean, and leave your home better than they found it.

Whether you are replacing an aging panel that can no longer carry modern loads, adding a circuit for a kitchen remodel, chasing a breaker that keeps tripping, installing a charger for a new EV, or putting in a standby generator before the next storm season, we deliver safe, code-compliant work and explain the options in plain language before anything is installed.

Whole-home and standby generator installation

Houston homeowners lose power to hurricanes, tropical storms, ice events, and grid strain during summer peaks. A permanently installed standby generator sits outside the home like a condenser unit, monitors utility power, and starts automatically within seconds of an outage — no extension cords, no refueling in the dark, no carbon monoxide risk from a portable unit parked too close to the house.

We size the unit to what the home actually needs rather than selling the largest model on the shelf. That means walking the home, listing the circuits that genuinely have to stay live — refrigeration, air conditioning, well or sump pumps, medical equipment, internet and security — and matching the generator and transfer switch to that load. Undersizing leaves you in the dark; oversizing is money spent on capacity you will never call on.

A correct installation involves more than setting the unit on a pad. It includes the automatic transfer switch, a code-compliant gas supply with adequate volume, the concrete or composite pad, bonding and grounding, permitting and inspection, and a commissioning test under real load. We handle the whole sequence and register the equipment so the manufacturer warranty starts clean.

EV charger installation for Houston homes

A Level 1 charger on a standard household outlet adds only a few miles of range per hour, which is why most Houston EV owners move to a Level 2 charger on a dedicated 240-volt circuit and recover a full battery overnight. The install itself is usually straightforward; the part that needs an electrician's judgment is whether the existing service can carry the new load.

We perform a load calculation before quoting, not after. If the panel has capacity, we run a dedicated circuit with the correct breaker, conductor size, and GFCI protection for the location. If it does not, we tell you plainly and price the panel upgrade alongside it, rather than discovering the problem mid-install. Garage, carport, and outdoor installations each carry different requirements for conduit, weather rating, and mounting height.

See our EV charger installation page for hardwired versus plug-in options, charger placement, and permitting.

Electrical panel and breaker upgrades

Many Houston homes are still running the service panel they were built with. Air conditioning, EV charging, induction ranges, tankless water heaters, pool equipment, and home offices place demands on that panel no one anticipated when it was installed. The warning signs are familiar: breakers that trip under normal use, lights that dim when a large appliance starts, warm cover plates, a burning smell, or a panel with no space left to add a circuit.

Some panels are worth more than an upgrade conversation — certain older brands have documented failure histories, and insurers increasingly ask about them. We inspect what is actually in the home, tell you whether a repair, a sub-panel, or a full service upgrade is the honest answer, and handle the utility coordination, permitting, and inspection that a service change requires.

Rewiring, circuits, and remodel electrical

Older Houston housing stock often hides cloth-insulated wiring, ungrounded two-prong outlets, aluminum branch circuits, or a decade of undocumented handyman work behind the drywall. Whole-home rewiring is disruptive and we do not recommend it lightly — but partial rewires, dedicated circuits for heavy appliances, and grounding corrections solve most problems without gutting the house.

For remodels and additions, bringing an electrician in during planning is far cheaper than after the walls close. We lay out circuits, lighting, and device locations against how the room will actually be used, and keep the work inspection-ready from the start.

Electrical safety inspections

A safety inspection is worth booking when you are buying or selling a home, after major storm or flood exposure, when an insurer asks, or simply when a house has never had its electrical system properly looked at. We check the panel and breakers, grounding and bonding, GFCI and AFCI protection in the locations code requires, outlet polarity, visible wiring condition, and smoke alarm placement — then give you a written summary separating genuine safety issues from things that are merely dated.

Emergency residential electrical repair

Some faults cannot wait for business hours. Burning smells, scorched or discolored outlets, sparking devices, a panel that is hot to the touch, a partial outage while neighbours still have power, or arcing after storm damage all warrant an immediate call. Our 24/7 emergency line is (832) 970-3101. If you smell burning or see smoke, cut power at the main breaker if it is safe to reach and call from outside the home.

Houston neighborhoods and surrounding areas we serve

We work throughout the Houston metro, including Memorial and Spring Branch, the Heights and Garden Oaks, Oak Forest, Near Northside, Uptown and the Galleria area, Jersey Village, Champions and northwest Houston, and south and southwest Houston. Beyond the city we serve Katy, Sugar Land, Cypress, Pearland, Spring, Tomball, Humble, The Woodlands, and more across the Houston metro service area.

Common questions from Houston homeowners

Do I need a permit for residential electrical work? Panel changes, service upgrades, new circuits, generator installations, and EV charger circuits generally require a permit and inspection in the City of Houston and surrounding jurisdictions. We pull permits as part of the job — unpermitted work tends to surface later during a sale or an insurance claim.

How long does a standby generator installation take? The on-site electrical and gas work is typically completed in a few days once equipment is on hand, but permitting, utility or gas coordination, and inspection scheduling extend the overall timeline. We give you a realistic schedule up front rather than an optimistic one.

Will a Level 2 EV charger require a panel upgrade? Not always. It depends on your existing service size and current load. We run the calculation before quoting so the answer is known before work begins.

Why does my breaker keep tripping? A breaker doing its job is a symptom, not the fault. It usually means an overloaded circuit, a short, a ground fault, or a failing breaker. Repeatedly resetting it without finding the cause is how electrical fires start.
