You flip a switch and the lights come on. You plug in your phone and it charges. Your AC runs all summer without tripping breakers every other day.
That’s what a properly functioning electrical system looks like. But if you’re dealing with flickering lights, outlets that don’t work, or breakers that trip when you run the dishwasher and microwave at the same time, your system isn’t keeping up with what you’re asking it to do.
Most homes in The Colony built before 2000 weren’t wired for the electrical load we put on them today. You’ve got smart TVs, gaming systems, home offices, EV chargers, and central air running simultaneously. Your panel might be rated for 100 amps when you actually need 200. That’s not a minor inconvenience—it’s a safety issue.
We handle the full scope of electrical work: circuit upgrades, panel replacements, wiring services for additions or remodels, whole-house surge protection, generator installations, and the kind of electric repair company work that fixes the problem instead of masking it. You get code-compliant installations, licensed electricians on every job, and systems designed to handle your actual electrical load—not what worked in 1995.
Carroll Service Co has been serving The Colony and the surrounding DFW area since 1999. We’re a family-owned electrical contractor with an A+ Better Business Bureau rating and multiple Super Service Awards from Angie’s List—not because we’re the cheapest, but because we show up on time, do the work right, and stand behind every job.
Every electrician on our team carries current Texas licensing and full insurance. We pull permits when required, follow NEC code standards, and use commercial-grade materials that last decades longer than the standard residential parts most contractors install.
The Colony sits in a deregulated electricity market, which means you’re already paying attention to energy costs and system performance. We work with that. Our installations are designed for efficiency, safety, and long-term reliability—so you’re not calling someone back in two years to redo what should’ve been done correctly the first time.
You call or submit a request online. We schedule a time that works for you—often same-day if it’s urgent. One of our licensed electricians shows up in a fully stocked truck, which means most repairs get completed during the first visit.
We assess the issue, explain what’s going on in plain terms, and give you upfront pricing before any work starts. No surprises when the job’s done. If it’s a panel upgrade, a generator install, or a bigger project, we walk you through the timeline, permitting process, and what to expect at each stage.
Once the work is complete, we test everything, clean up the site, and make sure you understand how to operate any new equipment. If permits were required, we handle the inspection scheduling. You get documentation of the work, warranty information, and a system that’s safe and up to code.
Most electrical problems don’t fix themselves. They get worse. A breaker that trips occasionally becomes a fire hazard. An outlet that sparks once will spark again. We’ve seen it hundreds of times across The Colony, and the cost of waiting almost always exceeds the cost of fixing it now.

We handle electrical repairs—outlets that don’t work, switches that fail, circuits that trip, and lighting issues. We replace outdated breaker panels that can’t handle modern electrical loads, upgrade wiring in older homes, and install whole-house surge protection to guard against Texas storms and power spikes.
Generator installations are a big part of what we do in The Colony. Summer heat and winter freezes knock out power, and a backup generator keeps your AC, refrigerator, and essential systems running. We size the unit correctly, handle the permitting, and connect it to your electrical system so it kicks on automatically when the grid goes down.
We also install EV chargers, recessed lighting, smart home electrical components, and USB outlet combinations. If you’re adding square footage or finishing a garage, we run the wiring and set up the electrical infrastructure to support it. Every installation meets current code requirements and gets inspected if required by the city.
The Colony’s housing stock ranges from newer builds to homes from the 1980s and 90s. Older homes often need panel upgrades, rewiring, or updated grounding systems to meet today’s safety standards. We assess what you actually need—not what generates the biggest invoice—and explain the options in terms that make sense.
If your breakers trip frequently, you smell burning near the panel, or you see rust and corrosion on the box, those are clear signs your panel is failing. Panels typically last 25 to 40 years, so if your home was built in the 1980s or 90s and still has the original panel, it’s worth having someone take a look.
Another indicator is capacity. Most older homes in The Colony have 100-amp panels, which can’t handle the electrical load of modern appliances, HVAC systems, EV chargers, and home offices running simultaneously. If you’re adding square footage, installing a generator, or upgrading to central air, you’ll likely need a 200-amp panel to support it.
Federal Pacific and Zinsco panels are known fire hazards and should be replaced immediately. These brands were installed in thousands of homes and have documented failure rates that create serious safety risks. If you’re not sure what brand you have, we can identify it in minutes and tell you whether replacement is necessary or just recommended.
A service call covers the cost of sending a licensed electrician to your home, diagnosing the issue, and providing an estimate for the repair. That fee typically ranges from $75 to $150 depending on the company and whether it’s a standard visit or an emergency call.
The repair cost is separate and depends on what’s wrong—replacing a faulty outlet might run $150 to $250, while rewiring a circuit or upgrading a subpanel could be $500 to $2,000 or more. Reputable electrical contractors give you a clear breakdown before starting work, so you know exactly what you’re paying for.
Some companies waive the service call fee if you move forward with the repair. Others build it into their pricing structure. Either way, you should get upfront pricing with no surprises when the job’s done. If an electrician starts work without explaining costs, that’s a red flag.
Most whole-house generator installations take two to three days from start to finish, not counting permitting time. Day one involves site prep, pouring a concrete pad, and setting the generator in place. Day two covers the electrical connections, gas line hookup (if you’re using natural gas), and transfer switch installation. Day three is testing, final inspections, and walkthrough.
Permitting in The Colony typically adds a week or two to the timeline, depending on the city’s workload. We handle the permit applications and schedule inspections, so you don’t have to deal with that process. Once permits are approved, we coordinate the install around your schedule.
Generator size matters. A 22kW unit that powers essential circuits—AC, refrigerator, a few outlets—costs less and installs faster than a 48kW unit that runs your entire home. We’ll assess your electrical load, explain the options, and recommend a size that matches your actual needs and budget. Generators are a significant investment, but if you’ve sat through a Texas summer without power, you already know why people install them.
In most cases, yes. If your panel is undersized but your wiring is in decent shape, you can upgrade to a 200-amp panel without touching the branch circuits. That gives you more capacity for additional appliances, HVAC upgrades, or an EV charger without the cost of a full rewire.
However, if your home still has knob-and-tube wiring, aluminum wiring, or cloth-insulated wiring from the 1950s and 60s, those are safety hazards that need to be addressed. Aluminum wiring, in particular, has a high failure rate and is a known fire risk. In those situations, a full or partial rewire isn’t optional—it’s necessary.
We can assess your wiring during an inspection and tell you what’s safe to keep and what needs replacement. Sometimes it’s just a few circuits that need updating. Other times, especially in older homes, the wiring is degraded enough that a full rewire makes more sense than patching problems as they come up. We’ll give you an honest assessment and explain the costs and benefits of each option.
Start with licensing and insurance. Every electrician working on your property should carry a current Texas electrical license and liability insurance. If they can’t provide proof of both, don’t hire them. Unlicensed work isn’t just illegal—it voids your homeowner’s insurance if something goes wrong.
Check their reputation. Look for an A+ BBB rating, positive reviews on Google and Angie’s List, and a track record of completing jobs on time and within budget. Ask for references from recent projects similar to yours. A contractor who’s been in business for 20+ years and has consistent positive feedback is a safer bet than someone who just started last year.
Get upfront pricing. A reputable electrical contractor will assess the job, explain what needs to be done, and give you a written estimate before starting work. If someone gives you a vague “we’ll figure it out as we go” answer, walk away. You should know what the job costs before anyone picks up a tool.
Power strips protect individual devices, but they don’t stop surges at the source. A whole-house surge protector installs at your electrical panel and blocks voltage spikes before they reach your outlets. That protects hardwired appliances like your HVAC system, water heater, garage door opener, and built-in electronics that aren’t plugged into power strips.
Texas has unpredictable weather, and power surges happen more often than people realize—lightning strikes, grid switching, downed power lines, and even large appliances cycling on and off can cause voltage spikes. A single surge can fry your AC’s control board, damage your refrigerator’s compressor, or destroy your home’s electrical system. Replacing those components costs thousands.
Whole-house surge protection costs a few hundred dollars to install and lasts 10+ years. It’s not glamorous, but it’s one of the smartest investments you can make for long-term electrical safety. Pair it with quality power strips for sensitive electronics, and you’ve got layered protection that actually works.
