Frequently Asked Questions
Can I save money by doing my own electrical work?
In South Carolina, homeowners can wire their own home, but it's not recommended. Mistakes are costly and dangerous. Licensed electricians ensure code compliance, pass inspections, and protect your investment.
How long does it take to wire a new home?
Rough-in typically takes 3-7 days depending on home size and complexity. Trim-out (installing switches, outlets, and fixtures) takes another 2-4 days after drywall is up.
Should I upgrade to a 400-amp service?
If you plan to add an EV charger, generator, workshop, or ADU in the future, 400-amp is worth the investment. Sikes Electrical can help you decide based on your future plans.
