Upgrade your home's electrical panel to safe, modern 200-amp service. We replace Federal Pacific, Zinsco, and outdated panels across St. Louis City and County — fully permitted and inspected.
Your electrical panel is the heart of your home's electrical system. It distributes power to every circuit in your house, and if it's outdated, undersized, or from a recalled manufacturer, it's not just an inconvenience — it's a safety hazard. We specialize in panel upgrades for St. Louis homes, handling everything from the initial assessment to the final inspection.
These two brands have well-documented histories of breaker failure. Federal Pacific Stab-Lok breakers have been shown to fail to trip during overcurrent conditions, meaning a short circuit that should flip a breaker instead keeps pushing current until wiring overheats. Zinsco breakers can fuse to the bus bar, making them impossible to trip. Both brands are extremely common in St. Louis homes built between the 1950s and 1980s. If your home has either brand, replacement isn't optional — it's urgent.
Every panel upgrade includes removal of your old panel, installation of a new 200-amp panel with modern breakers, proper grounding and bonding, labeling of all circuits, coordination with Ameren Missouri for meter disconnect and reconnection, pulling permits through St. Louis City or County (depending on your location), and scheduling the final inspection. We leave your electrical system clean, labeled, and code-compliant.
Panel upgrade costs vary depending on your home's existing wiring condition, the complexity of the installation, and whether any additional work is needed (like upgrading your service entrance or weatherhead). We provide free, detailed estimates before any work begins — you'll know the exact price and scope before we start. No surprises.
All panel upgrades require electrical permits. In St. Louis City, permits go through the Building Division. In St. Louis County, they're routed through the Department of Public Works. Individual municipalities like Kirkwood, Webster Groves, and Wildwood may have additional requirements. We handle all permitting and inspection scheduling — you don't need to deal with any of the paperwork.

Yes — always. Panel upgrades in St. Louis City, St. Louis County, Jefferson County, and St. Charles County all require a permit and a post-installation inspection. We pull all permits and coordinate the inspection as part of every job.
A straightforward panel upgrade takes 4 to 8 hours. More complex jobs — such as those requiring a meter socket replacement or Ameren Missouri service upgrade — may take a full day. We coordinate the Ameren disconnect/reconnect so you're not left without power overnight.
Most homes built before 1990 benefit from upgrading to 200A service. If you're adding an EV charger, a hot tub, or a home addition, 200A is typically the minimum. Larger homes or those with multiple EV chargers may need 400A. We assess your load during the free estimate.
Yes. We handle all coordination with Ameren Missouri for the utility disconnect and reconnect required during a panel upgrade. You don't need to contact Ameren separately — we manage the scheduling as part of the job.
Yes. Both brands have documented failure modes where breakers don't trip during overloads, creating a fire hazard. Most Missouri insurance companies will not renew a homeowner's policy on a home with a Federal Pacific Stab-Lok panel. Replacement is strongly recommended.
