Upgrade outdated electrical panels to modern systems that handle higher power demand safely.
Your electrical panel is the heart of your home's power system. If it's outdated, undersized, or showing signs of failure, upgrading it isn't optional — it's a safety necessity. Big State Electricians performs electrical panel upgrades and replacements for homes and businesses throughout SeaTac and Dallas-Fort Worth, with full permitting, inspection coordination, and same-week scheduling available.
Your panel may need replacement or upgrade if breakers trip frequently even under normal load, you still have a fuse box, your home has 60- or 100-amp service with modern appliances, lights dim when appliances turn on, you're installing an EV charger or major appliance, or your panel is a recalled brand such as Federal Pacific (Stab-Lok) or Zinsco. These aren't cosmetic issues — they're safety hazards.
Most modern homes require at least 200-amp service to safely support current electrical demand. If your home has 100-amp or smaller service, upgrading to 200A provides headroom for EV chargers, air conditioning, home offices, and modern kitchen appliances without overloading circuits.
A panel upgrade involves shutting off power at the utility level (coordinated with your utility company), removing the old panel and breakers, installing a new main panel, transferring circuits, adding new breakers as needed, reconnecting the service entrance, and scheduling the inspection. We handle everything from permit to final inspection.
For large homes, detached garages, workshops, or multi-unit properties, a sub-panel brings power distribution closer to where it's needed. We install sub-panels that tap off the main panel and provide dedicated circuits to a secondary location.
Panel upgrade costs vary based on service size, condition of existing wiring, and local utility requirements. We provide upfront quotes after assessing your specific situation. Call for a free estimate.
Most panel upgrades are completed in one day. Power will be off for several hours during the replacement. We coordinate the shutoff window with your utility company.
