Your breakers keep tripping. Your lights dim when the AC kicks on. Or maybe you’re just tired of wondering if your electrical panel can actually handle what you’re asking it to do.
Most homes in Justin built before 2000 are running on 100-amp panels that weren’t designed for today’s load. Add a few smart devices, a second fridge, an EV charger, and suddenly you’re pushing a system past its limit. That’s not just inconvenient—it’s a fire hazard.
When you call us, you’re working with a local electrician in Justin, TX who knows exactly what older homes in this area need. We’ll assess your current setup, explain what’s actually going on, and give you a clear path forward. No upselling. No pressure. Just honest electrical services that bring your home up to code and keep your family safe.
Carroll Service Co is a family-owned electrical contractor based in Fort Worth, serving Justin and the surrounding DFW Mid-Cities for over 25 years. We’re not a franchise. We’re not a call center. You’re getting the same crew, the same standards, and the same attention whether it’s your first call or your fifth.
We hold an A+ rating with the Better Business Bureau and multiple Super Service Awards from Angie’s List because we show up on time, do the work right, and don’t leave until you understand what we did and why. Our electricians are fully licensed by the Texas Department of Licensing and Regulation and carry comprehensive insurance on every job.
Justin is growing fast, and we’ve worked in enough homes here to know what you’re dealing with—whether it’s aging infrastructure near the older parts of town or new construction that still needs backup power for storm season.
First, you call or submit a request online. We’ll ask a few questions to understand what’s going on—whether it’s an emergency or something you’ve been putting off for months. If it’s urgent, our 24 hour electrician team can typically get to Justin within 60 to 90 minutes.
When we arrive, we assess the situation and walk you through what we find. You’ll get upfront pricing before we touch a single wire. No hidden fees. No surprises when the invoice shows up. If the job requires a permit, we handle that too—along with the inspection to make sure everything passes the first time.
Once you approve the work, we get started. Most residential electrical repairs and upgrades are completed the same day. For bigger projects like whole-house generator installations or full panel replacements, we’ll give you a clear timeline and keep you updated as we go. When we’re done, we test everything, clean up, and make sure you know how to use or maintain whatever we installed.

We handle the full scope of residential and commercial electrical services in Justin, TX. That includes electrical panel upgrades for homes that can’t keep up with modern demand, whole-house surge protection to guard against Texas storms, and backup generator installations so you’re not sitting in the dark when the grid goes down.
If your home was built before 1990, there’s a good chance your wiring wasn’t designed for the load you’re putting on it today. We’ll inspect your breaker panel, check for code violations, and recommend upgrades that actually make sense for how you live. We also install recessed lighting, handle electrical safety inspections, and troubleshoot issues like flickering lights, dead outlets, or circuits that won’t reset.
Justin sits right in the path of severe weather that rolls through North Texas, and power outages are more common than they should be. A whole-house generator keeps your HVAC, refrigerator, and essentials running without you lifting a finger. We’re certified to install Generac and other commercial-grade systems, and we pull all permits and handle inspections so the job is done right.
Every service comes with transparent pricing, licensed electricians, and the same level of care whether it’s a small repair or a full rewire.
If your panel is over 25 years old, you’re already in the replacement window. Panels don’t last forever, and the components inside degrade over time—especially in Texas heat.
You’ll also want to consider replacement if you’re experiencing frequent breaker trips, even after resetting them. That’s a sign your system is overloaded or the breakers themselves are worn out. Other red flags include a burning smell near the panel, visible rust or corrosion, or if you’re still using a Federal Pacific or Zinsco panel—both of which are known fire hazards.
Most homes in Justin built before 2000 have 100-amp panels. If you’ve added any major appliances, EV chargers, or a home office setup in the last few years, you’re likely pushing that system beyond what it was designed to handle. Upgrading to a 200-amp panel gives you the capacity to run everything safely without constant trips or worrying about overheating wires.
First, check if your neighbors still have power. If they do, the issue is likely isolated to your home—possibly a tripped main breaker or a problem with your meter. Head to your electrical panel and look for any breakers in the “off” or middle position, then reset them.
If the whole block is dark, it’s a grid issue and you’ll need to wait for the utility company to restore service. But if your power comes back on and then cuts out again a few minutes later, that’s a sign of a bigger problem—possibly a damaged service line, faulty panel, or an issue with your home’s grounding system.
That’s when you call us. We can diagnose whether the issue is on your side of the meter or something the utility needs to handle. And if you’re tired of losing power every time a storm rolls through, we can talk about installing a backup generator so you’re not dependent on the grid. Most whole-house systems kick on automatically within seconds of an outage, and they’ll keep your essentials running until power is restored.
Panel upgrades in Justin typically range from $2,000 to $4,500, depending on the size of the new panel, the condition of your existing wiring, and whether we need to relocate the panel or upgrade your meter base. If your home still has aluminum wiring or outdated breakers, that can add to the scope.
We give you a firm price before we start, so there’s no guessing. That price includes the new panel, all necessary breakers, labor, permits, and the inspection. If we find something during the assessment—like a grounding issue or damaged wiring—we’ll walk you through it and explain what it’ll take to fix it.
A 200-amp panel is the standard upgrade for most homes today, and it gives you the capacity to add EV chargers, backup generators, or additional circuits without overloading the system. It’s not the cheapest home improvement project, but it’s one of the most important. A failing panel is a fire risk, and upgrading now means you’re not dealing with emergency repairs later when something finally gives out.
Yes—especially if you’ve invested in expensive electronics, smart home systems, or appliances you don’t want to replace every few years. Texas storms bring lightning strikes and power surges that can fry everything from your HVAC system to your Wi-Fi router in a split second.
A whole-house surge protector installs directly at your electrical panel and stops surges before they reach your devices. It’s different from the power strips you plug into the wall—those only protect what’s plugged into them. A panel-mounted surge protector covers your entire home, including hardwired systems like your AC, water heater, and garage door opener.
Installation takes a few hours, and the cost is a fraction of what you’d spend replacing a fried HVAC board or a damaged refrigerator compressor. We install commercial-grade surge protection that’s rated to handle the kind of voltage spikes common in North Texas. If you’ve ever had to replace electronics after a storm, this is one of those upgrades that pays for itself the first time it saves you from a major loss.
Most whole-house generator installations take two to three days from start to finish. That includes running the gas line or propane connection, pouring a concrete pad, installing the transfer switch at your electrical panel, and wiring everything to code.
We handle all the permits and coordinate the inspections, so you’re not dealing with the city or the utility company. Once the generator is installed, we’ll test it under load to make sure it kicks on properly and runs all the circuits you’ve prioritized—usually your HVAC, refrigerator, lights, and a few outlets.
Generac and other standby generators are designed to start automatically within 10 seconds of losing grid power, and they’ll run as long as needed until service is restored. You don’t flip a switch or haul anything out of the garage. It just works. If you’ve sat through a Texas outage in July with no AC or dealt with spoiled food after a multi-day blackout, a backup generator is one of the best investments you can make. We’ll size it based on your home’s load and walk you through maintenance so it’s ready when you need it.
Yes. We’ve been doing commercial electrical services in the DFW area for over 25 years, and we’re fully licensed and insured to handle everything from tenant build-outs to service upgrades and code compliance work.
Commercial jobs are different from residential—you’re dealing with three-phase power, higher voltage systems, and stricter code requirements. We’ve worked with retail spaces, offices, warehouses, and restaurants throughout Justin and the surrounding Mid-Cities, so we understand the timelines and the standards you’re working under.
Whether you need new circuits for equipment, emergency lighting installations, panel upgrades to support additional load, or troubleshooting for an electrical issue that’s slowing down your operation, we’ll assess the situation and give you a clear plan. We coordinate with inspectors, pull permits, and make sure the work passes the first time so you’re not dealing with delays or failed inspections. If you’re opening a new location or upgrading an existing space, we’ll work around your schedule to minimize downtime and keep your project moving.
