Duncanville Electrical Company serves Duncanville and the surrounding Dallas County area for residential and commercial electrical work. Whether you need a tripped breaker diagnosed, a panel upgraded for a new appliance, or a full wiring inspection before a home sale, this is the call to make. We trace the fault. We fix the wiring. We restore the power.
Call (469) 249-3264 for a quote and get straight answers about your panel and wiring before anything is scheduled.
Here's what most people get wrong about their wiring: the symptom they can see is rarely the whole problem. Flickering lights usually point to a loose connection somewhere in the circuit, not the bulb. A dead outlet is often a tripped GFCI upstream, but it can also be a failed breaker or a wiring fault deeper in the wall. A breaker that trips repeatedly is telling you the circuit is overloaded or that the breaker itself is failing.
Partial power loss, where half the house goes dark while the rest stays on, typically means one leg of the service entrance has a problem. A burning smell from an outlet or a switch that feels warm to the touch are signs of resistance building up in a connection, and those warrant a call without delay. Sparking outlets and smoke from the panel fall into the same category. We run diagnostics to find where the fault actually lives, not just where it shows up.
GFCI and AFCI protection failures get misread often, too. A GFCI that won't reset may have tripped from a fault downstream, and replacing the device without tracing the cause leaves the problem in place. We'll find the fault and fix it right.
Some homes need a full rewire. Others just need one outlet fixed. And some need a panel that can actually carry the load the house is putting on it.
The most common request we handle in this category is the 100-to-200-amp service upgrade. Older homes in Duncanville and across Dallas County were built when electrical loads were far lighter than what modern households place on a service. A fuse box or an undersized breaker panel that was adequate for a 1970s household is not adequate for a home with a modern kitchen, a home office, and a Level 2 EV charger on the same service. Load calculations determine what the panel actually needs to carry before any work is scoped.
Panels also get upgraded ahead of a major appliance installation, after a failed inspection, or when a homeowner adds square footage and the existing service can't support the new circuits. Electrical work done to the code inspectors here enforce is what gets the permit closed and the project finished without callbacks.
GFCI outlets are required by code in kitchens, bathrooms, garages, and outdoor locations. AFCI protection is required in bedrooms and living areas in most residential builds and renovations. These are not optional upgrades in most situations. When an older home hasn't been updated to current code, a remodel or a pre-sale inspection will surface the gaps quickly.
Dimmer switch installation, standard switch replacements, and adding outlets to rooms that were wired for a different era are straightforward jobs that make a real difference in how a space functions. Adding a circuit is often simpler than people expect. We assess what the panel can support, run the wiring, and install the device correctly the first time. Call and we'll handle the lights, outlets, and panel.
For residential and commercial electrical work alike, lighting is one of the most requested installs we handle. Interior work covers recessed lighting layouts, under-cabinet wiring, fixture swaps, and task lighting in kitchens and workspaces. Exterior work includes security lights, motion sensor lights, and landscape wiring for paths and driveways.
Ceiling fan installation involves more than swapping a fixture. Where no ceiling box exists, we run the wiring, install a rated box, and hang the fan correctly. Replacements in rooms that already have a box are faster, but the wiring still needs to be confirmed before anything goes up. We handle both.
Dryers, electric ranges, refrigerators, and hot tubs each require their own dedicated circuit. Sharing a circuit with other loads is a code violation and a practical problem. When a large appliance trips a breaker repeatedly, a dedicated circuit is usually the fix.
Remodels and additions create demand for new circuits across the board. A kitchen renovation typically needs updated outlet placement, new circuits for appliances, and GFCI coverage throughout. A basement finish needs lighting circuits, outlets, and often a sump-pump circuit on its own breaker. Garage builds and additions follow the same pattern.
Pool and hot tub electrical work covers the supply side: the wiring, the disconnect, and the dedicated circuit that feeds the equipment. When the main panel is full, a subpanel may be the right answer before any of that work begins.
The homes and wiring in this area have their own quirks, and older neighborhoods in Duncanville are no exception. Knob-and-tube wiring, aluminum branch circuit wiring, and ungrounded two-prong outlets show up regularly in homes built before the 1980s. None of those systems are compatible with the way modern homes use power, and insurance carriers increasingly take notice.
Pre-sale inspections surface these issues more often than homeowners expect. Buyers call after an inspection report flags the wiring. Sellers call to get ahead of it before the house goes on the market. In both cases, we assess the scope, explain what the inspection found, and give a clear picture of what a partial or full rewire involves before any work starts. The work area is left as it was found when the job is done.
A Level 2 home charger runs on a dedicated 240V circuit. That means a new circuit from the panel, wiring run to the garage or driveway, and a panel capacity check before anything else. If the panel is already running near its limit, an upgrade may need to happen first.
The practical questions to settle before the visit: where the charger will be mounted, how far the run is from the panel, and whether the panel has capacity to spare. We work through all of that on the call and confirm the price before scheduling. If you have a vehicle arriving soon and no charger in place, call for a quote now rather than after delivery.
Dallas County's climate puts specific demands on residential electrical systems that homeowners in milder parts of the country don't face in the same way. Long summers, severe thunderstorm seasons, and the occasional ice storm or grid event make the following services a regular part of what we handle in this area.
Texas summers run long and hot, and extended air conditioning seasons put sustained load on panels for months at a time. A panel running near capacity under that kind of continuous demand is more likely to show stress than one that only sees peak loads occasionally. Older neighborhoods in Duncanville still have fuse boxes and 100-amp panels that were sized for a different era. The 200-amp upgrade is the most common solution, and load calculations tell us whether that's the right size or whether the service needs to go further.
Texas grid events and severe weather have made generator hookups a practical conversation across Dallas County rather than a niche request. We handle the electrical side of the installation: the transfer switch, the dedicated circuit, and the connection to the home's panel. The transfer switch is what keeps the generator from back-feeding the grid and what allows the home to switch between utility power and generator power safely. Call to discuss what the hookup involves for your specific panel and home layout.
Summer thunderstorm activity in the Dallas area is consistent and sometimes severe. A surge that comes through the utility line during a storm can damage electronics, appliances, and the equipment that runs your home's climate control. Whole-panel surge protection catches that energy at the point of entry before it reaches individual circuits. It is a single installation at the panel, and it covers the whole house from that point forward. Give us a call and consider it handled.
Property managers have their own priorities when the power goes out, and they differ from a homeowner's. A dead outlet in a rental unit needs to be addressed before it becomes a habitability issue. A tripped breaker in a commercial space affects operations, not just convenience. We work with homeowners, landlords, property managers, and small businesses across Duncanville and nearby areas including Cedar Hill, DeSoto, Lancaster, Grand Prairie, and Glenn Heights.
For residential clients, that covers everything from older-home rewiring to new construction circuits. For commercial and rental clients, it covers repairs, panel work, outlet and lighting upgrades, and code-compliance corrections. We are available every day from 6:30 AM to 8:30 PM, which makes scheduling around tenant access or business hours a practical conversation rather than a problem.
An electrical inspection covers the panel condition, grounding and bonding, outlet types and placement, visible wiring, and AFCI and GFCI coverage. The result is a clear picture of what the system looks like against current code and where the gaps are.
People call for inspections before buying a home, before listing one, to satisfy rental compliance requirements, or after a renovation to confirm the work is ready for sign-off. If the inspection finds issues, we explain what each one means and what fixing it involves. Nothing gets scheduled without a price confirmed first.
The price for any job is confirmed on the call, before anything is scheduled. Ask what it covers and you get a straight answer. We are open every day from 6:30 AM to 8:30 PM, which means evenings and weekends are available for homeowners who can't take time off during the week and property managers who need work done around tenant schedules.
Emergency calls are answered. Ask what the schedule allows when you call. One call. One electrician. One price, agreed first.
Breakers that trip under normal use and won't stay reset, a panel that runs warm to the touch, a buzzing or humming sound from the panel, and no room to add new circuits are the most common signs. Older 100-amp panels feeding homes with central air conditioning, large appliances, and home offices are frequently the ones that have outgrown their capacity. A load calculation on the call helps determine whether an upgrade is the right next step.
A Level 2 EV charger requires a dedicated 240-volt circuit, and whether your panel can support it depends on the current load and the available breaker space. We run a panel capacity check before quoting the charger circuit. If the panel is already near its limit, a panel upgrade may need to happen first, and we factor that into the conversation before anything is scheduled.
A whole-home surge protector installs at the service panel and intercepts voltage spikes before they reach the wiring and connected devices. Dallas County's summer thunderstorm season sends surges through utility lines regularly, and cumulative spike damage to appliances and electronics often goes unnoticed until something fails. The installation is a single visit at the panel and covers every circuit in the home from that point forward.
The electrical side of a generator installation covers the transfer switch, the dedicated circuit the generator connects to, and the disconnect that isolates the generator from the utility line. The transfer switch is the critical piece: it prevents back-feed to the grid and allows the home to switch between utility and generator power safely. We handle the wiring and the panel connection. The generator itself is a separate piece of equipment.
GFCI protection is required by code in kitchens, bathrooms, garages, crawl spaces, and outdoor locations. AFCI protection is required in bedrooms and living areas in most residential builds and renovations. Older homes often lack both, and a pre-sale inspection or remodel will surface the gaps. We install both types as replacements and as part of larger circuit work.
Discoloration or scorch marks around the face of the outlet, a warm or hot cover plate, a loose fit when a plug is inserted, and a buzzing or crackling sound when something is plugged in are all signs that the outlet needs attention. A warm outlet is a warning sign, not a quirk, and it is worth a call rather than a wait-and-see approach.
If the scope changes on site, for example if the fault turns out to be in the wiring inside the wall rather than at the outlet, or if the panel needs additional work that was not visible during the initial description, that conversation happens before the additional work proceeds. You are told what the new scope involves and what it costs before anything changes. Nothing is added after the fact without your agreement.
Yes. An adult needs to be present to provide access to the panel and the affected areas, to confirm the scope before work begins, and to walk through the completed work before the electrician leaves. If you cannot be there, arrange for someone else who can make decisions about the job.
Every circuit or device worked on is tested before the job is called complete. Outlets are checked for correct wiring and ground continuity. Breakers are cycled. Lights and fans are run through their functions. For panel work, load distribution is confirmed and the panel is inspected before it is closed. We do not leave without verifying the repair or installation is functioning correctly.
Clear the area around the panel so it is fully accessible. Move furniture, storage, or anything else that blocks access to the outlets, switches, or fixtures involved in the job. In kitchens and bathrooms, clear the counter space near the outlets being worked on. The more accessible the work area, the faster the job goes.
Wiring inside finished walls is not visible until it is opened up. If a fault is located in a section of wiring that runs through a finished wall or ceiling, accessing it takes more time than a repair at an exposed junction. Older wiring, including aluminum branch circuit wiring or knob-and-tube, may also require additional steps to bring the repair up to current standards. We explain what is involved before the additional work proceeds.
A dedicated circuit is a single circuit run from the panel to one specific outlet or connection point, sized for the load it will carry. For a dryer, range, or EV charger, that means a 240-volt circuit with the correct wire gauge and breaker. For a workshop or large tool, the size depends on the equipment. We confirm the right specifications on the call and check panel capacity before quoting the work.
Outdoor wiring uses materials and methods rated for exterior exposure, including weatherproof boxes and covers, conduit where required, and GFCI protection at all outdoor outlets. The scope of exterior work, whether it is a security light, a driveway outlet, or wiring for a detached garage or outbuilding, is confirmed on the call before the visit.
Duncanville Electrical Company handles the full range of residential and commercial electrical work, from a single outlet repair to a whole-home rewire or panel upgrade. We serve Duncanville, Dallas County, and surrounding communities including Midlothian, Mansfield, Lancaster, and DeSoto.

What causes a breaker to trip repeatedly?
A breaker that trips under normal use is usually signaling one of three things: the circuit is carrying more load than it was sized for, a device on the circuit has a fault drawing excess current, or the breaker itself is failing and can no longer hold its rated load. Resetting it without finding the cause does not fix the problem. We run diagnostics to determine which of those is actually happening before recommending a repair or a circuit upgrade.
How do I know if the wiring in an older home is safe?
Older wiring systems, including knob-and-tube and aluminum branch circuit wiring, were designed for electrical loads that are a fraction of what modern homes use. They are not inherently dangerous in every case, but they are not compatible with how homes use power today, and they are increasingly flagged by insurance carriers. Flickering lights, warm outlets, and frequently tripped breakers are signs worth investigating. An inspection gives you a clear picture of what is in the walls and what, if anything, needs to change.
What does it mean when lights flicker or dim?
Occasional flickering when a large appliance starts up is common and usually points to a load issue on the circuit rather than a wiring fault. Persistent flickering, flickering across multiple rooms, or flickering that happens without an obvious trigger often points to a loose connection somewhere in the circuit or at the panel. Flickering lights and warm outlets are warning signs, not quirks, and they are worth a call rather than a wait-and-see approach.
Faults Traced Before Anything Is Replaced
We run diagnostics to find where the fault actually lives, not just where it shows up. Replacing a device without tracing the cause leaves the problem in place.
How do I know if my home needs a full rewire or just targeted repairs?
The answer depends on what is in the walls and how the existing wiring is performing. A home with knob-and-tube or aluminum branch circuit wiring throughout may be a candidate for a full rewire, especially if the system is being asked to carry loads it was never designed for. Homes with mostly updated wiring and isolated problem areas are often handled with targeted repairs or partial rewiring. We assess the scope on the visit and explain what the inspection found before any work is quoted.
What electrical work is needed to support a new air conditioner or heat pump?
We handle the electrical supply side: the dedicated circuit, the disconnect, and the panel capacity to carry the load. A new cooling unit typically requires a dedicated 240-volt circuit sized for the equipment's draw, and if the panel is already running near capacity, an upgrade may need to happen first. We confirm what the panel can support on the call and factor that into the quote before anything is scheduled. The equipment installation itself is handled by an HVAC contractor.
When should I call an electrician instead of handling something myself?
Replacing a light bulb or resetting a tripped breaker is a reasonable first step. Beyond that, anything involving wiring inside a wall, work at the panel, adding or replacing outlets and switches, or diagnosing a fault you cannot clearly identify is work that warrants a call. The risk with electrical DIY is not just the immediate task but what gets left behind in the wall or the panel. We can scope the job on the call and tell you what it actually involves before you decide.
Code-Compliant Work on Every Job
Electrical work done to the code inspectors here enforce is what gets the permit closed and the project finished without callbacks. That applies to every job, not just the ones that require a permit.
How are emergency electrical faults handled?
We are available every day from 6:30 AM to 8:30 PM, and emergency calls are answered within those hours. Ask what the schedule allows when you call. If you are dealing with a sparking outlet, a burning smell, smoke from the panel, or a partial power loss, call immediately rather than waiting for a convenient time. Those symptoms warrant prompt attention, so call as soon as you notice them.
What do I need to know about grounding and bonding in an older home?
Grounding and bonding are the parts of an electrical system that direct fault current safely away from people and equipment. Older homes often have two-prong ungrounded outlets, missing ground wires in junction boxes, or bonding that does not meet current standards. These gaps show up in pre-sale inspections and insurance reviews. We check grounding and bonding as part of a safety inspection and explain what updating it involves.
Scope Agreed Before the Panel Is Opened
The price and the scope are confirmed before any work starts. If something on site changes what the job involves, you hear about it and agree to it before we proceed.
How does pricing work and what do I find out when I call?
The price for any job is confirmed on the call, before anything is scheduled. We ask about the symptom or the work you need, scope what is likely involved, and give you a price before the visit is booked. If the scope changes on site because something in the wall or the panel is different from what was described, that conversation happens before the additional work proceeds. Nothing is added without your agreement.
What is involved in adding circuits for a workshop or home office?
A workshop or home office circuit is sized for the load it will carry, whether that is a 120-volt circuit for general outlets or a 240-volt circuit for larger equipment. We confirm the right wire gauge and breaker size on the call, check whether the panel has capacity to add the circuit, and run the wiring from the panel to the new location. If the panel is full, a subpanel may be the right answer before the circuit work begins.
How long does a panel upgrade typically take?
A standard 100-to-200-amp service upgrade is typically a full-day job. The timeline depends on the condition of the existing panel, whether the meter base or service entrance needs work, and whether any wiring inside the home needs to be updated at the same time. We give you a realistic scope on the call so you know what to expect before scheduling.
Call (469) 249-3264 any day between 6:30 AM and 8:30 PM and we will walk through what the job involves, confirm a price, and get it on the schedule.
