Mac Koul Electric Inc

MacKoul Electric is a Shrewsbury-based commercial and industrial electrical contractor, self-reporting more than 30 years of commercial experience. Its work runs toward businesses rather than homes — sign and parking-lot lighting repair and maintenance, service upgrades, permits and surveys, and emergency service — though one review also mentions residential jobs. There are only two written reviews on file. A 2025 review praised the crew's professionalism and said they handle large projects as easily as residential ones. In a 2023 review, someone identifying 16 years in the industry called MacKoul the best industrial and commercial electrical partner they'd worked with — a strong endorsement, if a niche one, from another business rather than a homeowner. The state registry verifies an active Massachusetts Master Electrician license held by Jeffrey A Laing, the company's licensed electrician of record. BBB shows the business as not yet rated, with no complaints on file. For commercial, industrial or sign-related electrical work in the Shrewsbury area, the limited written record is positive and the license checks out; for a purely residential job, it's worth confirming that's work they take on regularly.
