M.G Denson Electrical Services

M.G Denson Electrical Services is a Springfield electrical contractor run by Michael G Denson, and its record is a long one: the Better Business Bureau dates the business to 1 January 1988, 38 years, and opened its file on it in 2001. Massachusetts confirms electrician licence 13063 as active, with Michael G Denson as the registry holder of record. The work itself shows up in permits, and there are a lot of them — 629 projects on BuildZoom. The sample runs across western Massachusetts: Springfield, West Springfield, Westfield, Chicopee and Great Barrington. It includes a $30,000 rewire of a three-storey dwelling after a fire in West Springfield in 2025, the complete wiring of a four-storey Springfield building including fire alarm and data, knob-and-tube removal and service replacements in older homes in Great Barrington in 2023 and Springfield in 2021, mini-split and recessed-lighting work, and commercial fit-outs including McDonald's menu-board and drive-thru wiring. Three of the permits are jobs to correct wiring violations that inspectors had cited against the properties — remedial work this contractor was hired to perform, not action taken against him. A commenter on a review aggregator wrote that the contractor 'knows everything there is to know about old wiring, as well as new', which matches what the permits show but is a single unverified web comment. What is missing is customers speaking on the record. The BBB profile publishes no reviews, no complaints and no rating at all — it is shown as Not Rated because the bureau says it lacks sufficient information — and the business is not BBB accredited. The Procore profile also publishes no rating or reviews. That absence, not any negative account, is why the rating stays cautious. A few things to pin down before hiring. Sources disagree about where the business sits and what it is called: the BBB lists it at 4 Harvard Street, Springfield, as a sole proprietorship trading also as Denson MG Contracting, while Google and Procore put it at 562 St James Ave and LinkedIn calls it M.G Denson Electrical Services Inc. Its Procore profile names service areas only in New York and Connecticut, which sits oddly against a permit history entirely in western Massachusetts, so confirm your town is covered. BuildZoom lists a Department of Public Safety S-License (#SS1361) as inactive and at one point cancelled and has not re-verified record MAA13063 since 2015, so if your job involves alarm or security systems, ask who holds that licence. For old-house wiring, service replacements and knob-and-tube removal in the Springfield area, the permitted history here is deep; ask for recent references, since no customer reviews are published anywhere.
