Interstate Electrical Services

Interstate Electrical Services Corporation is a privately held electrical company based in North Billerica and serving New England. The company says it has operated since 1966, has more than 700 professionals across eight offices, and provides installation, design-build engineering, prefabrication, fire alarm, network, automation, and 24/7 emergency services. The public review record is mixed. Google shows 4.5 stars from 15 ratings; positive comments mention responsive leadership and a strong industry reputation, while two one-star comments criticize rude drivers and traffic behavior rather than describing electrical workmanship. BuildZoom lists 513 permitted projects and a score of 109, and BBB reports 60 years in business but no accreditation or rating. Interstate appears best suited to larger commercial, industrial, institutional, and residential electrical projects where its scale and specialty capabilities fit the job. Confirm the local office, project team, license details, and emergency-service scope before booking, especially because the company operates across several offices and the available customer comments do not provide much detail about completed electrical work.
