Common Mistakes to Avoid
- 1
Starting without a master electrician license — unlicensed electrical work is illegal and creates severe liability
- 2
Not building general contractor relationships from day one — GC subcontract work is the fastest growth path
- 3
Undercharging for panel upgrades — a 200A panel upgrade is a multi-hour skilled-labor job and pricing should reflect both the hours and the licensed-trade nature of the work
- 4
Not obtaining permits for permitted work — homeowners can face major issues at sale if work was unpermitted
- 5
Not tracking material costs per job — material markup is a significant profit center for electrical contractors
