22+ YEARS POWERING
LONG ISLAND
MJ Electrical Contracting was founded in 2000 with a straightforward mission: bring reliable, honest electrical work to Long Island homes and businesses. What started as a local operation has grown into one of the most trusted names in Nassau and Suffolk County electrical contracting.
Long Island's housing stock presents unique challenges — much of it was built in the 1950s and 60s with 60A or 100A panels, knob-and-tube wiring, and electrical systems never designed for modern loads. We understand these homes inside and out. Whether it's a full 200A panel upgrade, a new EV charger circuit, or troubleshooting a frustrating intermittent problem, we've done it thousands of times.
Every job we take gets the same attention: a proper site assessment, a clear explanation of what we're doing and why, clean workmanship, and the permits and inspections required by Nassau and Suffolk County. We don't cut corners — and our 146 Google reviews reflect that.
