What red flags should I watch for hiring an electrician in St. Louis?
Watch for electrical work quotes in St. Louis that lack line-item detail. A professional estimate breaks out labor, materials, permits, and cleanup separately. Lump-sum bids hide margin and make change orders impossible to evaluate.

Request certificates directly from the insurer, not just copies the contractor provides.

Modern codes have changed significantly since these homes were built — any work that triggers inspection should be priced with code upgrades included.
