The short answer
Electrical panel upgrade cost in Magnolia and Tomball depends on service size, the condition of the existing gear, aluminum versus copper, and whether CenterPoint has to set a new meter. Janezich Electric quotes 100A-to-200A replacements and subpanels as line items — labor and material — before the house goes dark.
Electrical panel upgrade cost in Magnolia and Tomball is never just the price of a box. The load center is the easy part. The number moves with service size, rusted nipples, aluminum versus copper, a full panel versus a few tandems, and whether CenterPoint has to set a new meter base.
Janezich Electric replaces overloaded and obsolete panels for Magnolia, Tomball, The Woodlands, and Texas homes and shops. You get a written proposal before we pull the meter.
Why 100-amp panels fail modern houses
A 1990s Magnolia home that added a second HVAC, a shop welder, a tankless water heater, or an EV charger is not the house the original 100-amp panel was built for. Breakers stack, kitchens share, and the first August afternoon trips the main.
What changes the price
A clean 200-amp swap on a reachable panel is one job. A rusted outdoor can, a full interior, a service change, or a meter-base replacement is another. We photograph the panel, the nipple, and the meter so the proposal matches the house — not a Facebook range.
What an honest proposal includes
Labor to make the house safe while power is down, a labeled load center, torque, and a plan for the utility. Line items show labor versus material. We do not hide a “service fee” after your kitchen is dark.
Commercial panels and subpanels
A tenant suite in The Woodlands or a shop in Tomball may need a subpanel, not a new utility service. We will say which one you are buying. After-hours installs are available Monday–Thursday 4–10pm.
How long power is down
Most residential replacements are a planned half-day to a day. We schedule around family or tenants. Utility-coordinated upgrades take longer because CenterPoint sets the calendar, not us.
Next step
Send photos of the panel door, the interior if it is safe to open, and the meter. Call 346-236-3512 or use the quote form. We will tell you if this is a Saturday swap or a utility-coordinated upgrade.
Common questions
How much does a panel upgrade cost in Magnolia, TX?
It depends on 100A versus 200A, the condition of the existing gear, and whether the utility has to change the meter. Janezich Electric quotes from photos so you see labor and material before we schedule.
How long does a 200-amp panel replacement take?
Most homes are a planned half-day to a day. If CenterPoint has to set a new meter, the calendar follows the utility.
Do I need a panel upgrade for an EV charger?
Often on a 100-amp service. We load-calculate first. If the main cannot carry the charger and two AC units in August, the upgrade goes on the same proposal.
Do you upgrade commercial suite panels?
Yes — shops and tenant spaces in Tomball, The Woodlands, Magnolia, and throughout Texas.
