What red flags should I watch for hiring an electrician in Marlborough?
Check that any Marlborough 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. In Marlborough, verify your electrical work contractor pulls the permit themselves — never pull it in your own name. If they ask you to pull the permit, they may not be properly licensed to do the work. For older Marlborough homes (average 52 years), beware of electrical work quotes that don't mention code compliance. Modern codes have changed significantly since these homes were built — any work that triggers inspection should be priced with code upgrades included.
