Electrical Service Upgrades in Joshua, TX

Your electrical service is the whole system that brings power from the utility into your home — the meter, the service entrance conductors, the main panel, and the main breaker. Its amperage rating (100 amps, 200 amps, and so on) is the maximum amount of current that system can safely deliver at once. When the loads in a home or business grow past what the service can deliver, breakers trip, lights dim, and the system runs closer to its limit than it should. A service upgrade raises that ceiling.

The most common upgrade we do is 100 amps to 200 amps, and the reasons are usually the same: a family has added an EV charger, a tankless water heater, a new air conditioner, a shop or outbuilding, or an addition — and the old 100-amp service simply wasn't built for that. We also upgrade services to accept a standby generator, and to bring an older home's entrance up to current code.

A service upgrade is bigger than a panel swap. It involves the utility, the meter, and the city, and it has to be coordinated — not just wired. Jim has been doing this work for 30+ years and knows how to run a service upgrade so the utility disconnects and reconnects on schedule, the inspection passes the first time, and your power is back the same day.

Reasons to consider a service upgrade:

• Your main breaker is 100 amps (or less) and you're adding meaningful new load — an EV charger, a tankless water heater, a second AC, a hot tub.
• Lights dim or flicker when a large appliance kicks on.
• You're building an addition, a shop, or converting a garage and need more circuits.
• You're adding a standby generator and your service needs to accept the transfer switch.
• Your service entrance equipment is old, weathered, or no longer meets code.
• Your panel is full and a sub-panel isn't the right answer.

Sometimes the right answer isn't an upgrade — it's a load calculation and a smaller fix. Jim does the math before he recommends anything. If a service upgrade isn't warranted, he'll tell you that too.

How Jim handles a service upgrade, step by step:

1. Load calculation. We add up the actual and planned loads in the home to confirm what amperage you need — 200 amps isn't always the answer, but it usually is for a modern household adding load.
2. Quote before any work. You get a written quote covering the panel, the service entrance conductors, the meter base, grounding, and the permit.
3. Utility coordination. The utility has to disconnect your service before we start and reconnect it when we're done. We handle that scheduling so the outage window is planned and short.
4. Service entrance and meter work. We replace the meter base and service entrance conductors, upgrade the grounding and bonding, and set the new panel and main breaker.
5. Inspection. Inspection requirements depend on the city — some require a rough-in inspection before the conductors are pulled, and a final after. We know the local requirements and schedule them so the utility can reconnect on time.
6. Reconnect and walkthrough. The utility reconnects, we energize and test every circuit, label the panel, and walk you through the new service.

We never quote a price without seeing the job — every home and every panel is different. What follows is an honest explanation of what drives the cost, not a price list. Jim will give you a clear, written quote before any work starts.

• Target amperage. A 200-amp upgrade costs differently from a 320-amp or 400-amp service.
• Service entrance type. Overhead (service drop) vs. underground (lateral) service changes what's involved in the conductor and mast work.
• Meter base and conductor length. The distance from the meter to the panel and the condition of the existing meter base affect materials and labor.
• Grounding and bonding. Bringing the grounding electrode system up to current code can add work, especially in older homes.
• Utility requirements. Some utilities require their own work or fees on their side of the meter.
• Permitting and inspection. Fees and inspection steps vary by city.
