4 Daughters Electric quotes panel upgrades in Gilbert, AZ after a load calculation and a look at your service, because the price depends on your amperage, grounding, panel location and the utility involved. National cost guides put a residential 200-amp upgrade in a broad range, but the honest number for your home comes from a site visit — not a web average.
Why there's no single price
Search "panel upgrade cost" and you'll find national averages from home-improvement cost guides like Angi and Forbes Home spanning a wide band — often quoted somewhere from around $1,500 to $4,000 or more for a service upgrade, with higher figures when the service size jumps or the job is complex. Those ranges are a reality check, not a quote, because the number for your specific home hinges on details a national average can't see. Here's what actually moves it.
The factors that drive the cost
Target amperage. Going from 100 or 125 amps up to 200 amps is the common request; a larger jump or a subpanel changes the material and labor. If you only need more breaker spaces rather than more amperage, a subpanel can be cheaper than a full service upgrade.
Grounding and bonding. Older Gilbert homes sometimes need their grounding and bonding brought up to current code as part of the upgrade, which adds labor and materials but is not optional.
Panel location and condition. An easily accessed exterior panel is quicker than one in a tight interior space, and weather-worn or damaged mounts add work.
Permit and utility coordination. A panel upgrade requires a Town of Gilbert permit and a utility disconnect and reconnect (SRP or APS), and those fees and scheduling are part of the total.
When an upgrade isn't the cheapest fix
Sometimes you don't need the whole upgrade. If a single breaker or lug failed, that's a panel repair. If the panel is a hazard brand, you may need a replacement rather than an upgrade. We'll tell you which situation you're in before quoting the larger job — because recommending work you don't need is how a shop loses a customer for good.
How to get a real number
The fastest path to an accurate price is a load calculation and a look at your service. If you're adding an EV charger, a heat pump or a pool, mention that up front, since sizing for those changes the recommendation. Call (480) 896-0325 and we'll give you a firm, up-front price for your home — no changeover-day surprises.
