What red flags should I watch for hiring a solar installer in Columbia?
Watch for solar installation quotes in Columbia 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 Columbia contractor doing solar installation carries both general liability insurance ($1M minimum) and workers' compensation. Request certificates directly from the insurer, not just copies the contractor provides.
