About This Market

UPDATED APR 2026

St Louis electrical market serves 300,000+ households with steady demand from aging housing stock built pre-1950s requiring panel upgrades and rewiring. Competition is moderate with approximately 200 licensed contractors serving metro area. Panel upgrades dominate residential work due to old 60-100 amp services, while commercial work centers on warehouse district renovations and healthcare facilities. Material costs and permit fees drive pricing - copper theft concerns have increased security requirements on job sites. Getting licensed in Missouri takes 3-4 months if you have experience documentation ready. St Louis Building Division moves permits efficiently but inspectors are thorough - rough-in work must be clean or you'll get kicked. Summer months are slammed with AC-related service calls and renovation work. Winter focuses on indoor projects and emergency repairs. Keep bonding current because commercial jobs require it upfront, and maintain good relationships with supply houses - material delays can kill schedules here.
