Service Overview
Expert Electrical Panel Upgrades in Greater St. Louis
A panel upgrade is not automatically the answer to every electrical problem. JL evaluates the existing service, panel condition, available capacity, grounding and bonding, and the loads you plan to add before recommending a replacement, subpanel, or targeted correction.
What This Service Covers
- Service and panel condition evaluation
- 200-amp upgrades where appropriate
- Breaker panel replacement
- Subpanel installation
- Renovation and equipment capacity planning
When to Call an Electrician
- The panel is damaged, crowded, corroded, or uses obsolete equipment
- You are adding an EV charger, electric HVAC, range, hot tub, or major addition
- Insurance or an inspection identifies panel concerns
- Breakers trip because the home has outgrown available capacity
How the Work Is Planned
Load and condition assessment
We document the existing service and major loads, inspect accessible equipment, and determine whether more capacity is actually needed.
Upgrade planning
We define panel size, breaker spaces, grounding and bonding corrections, utility coordination, and any related service equipment work.
Permit, installation, and inspection
Where required, the work is permitted and coordinated with the utility and local authority before energizing and labeling the new equipment.
Scope & Limitations
Panel work may include the load center, breakers, service conductors, grounding, bonding, and related disconnect equipment. Drywall repair, utility charges, trenching, and corrections outside the quoted scope are identified separately.
Permits & Electrical Code
Panel and service upgrades typically require permits and inspections. Requirements vary by municipality and may include exterior disconnects, surge protection, grounding electrode updates, and AFCI/GFCI changes.
Estimates & Rates
What Affects the Price?
Pricing depends on amperage, service configuration, equipment location, utility requirements, and required corrections. JL provides a project estimate after an on-site assessment.
