What pitfalls should I watch for hiring an electrician in Sunnyvale's HOA neighborhoods?
Watch for electrical work quotes in Sunnyvale 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. Check that any Sunnyvale contractor doing electrical work carries both general liability insurance ($1M minimum) and workers' compensation. Request certificates directly from the insurer, not just copies the contractor provides.
