Editorial Review
Our Take on D & M Master Electric L.L.C.
A 5.0 average across 262 Google reviews is hard to sustain in a trade full of permit delays and utility hold-ups, and that record is the main reason this one is worth a call. The service list is genuinely broad, covering panels, EV chargers, generators and commercial fit-outs rather than one niche. Get the licence number and a written scope, as with any electrical contractor, then judge on the quote.

Company Background
About D & M Master Electric L.L.C.
Electrical work in Newark splits fairly neatly into two worlds. There are the older frame houses and multifamily conversions in Vailsburg, Clinton Hill and Weequahic, many still carrying knob-and-tube remnants, 60 or 100 amp services, and two-prong outlets that fail a home inspection the moment a buyer's engineer walks in. Then there is the commercial and mixed-use stock around Downtown, Lower Broadway and the Ironbound, where tenant fit-outs, lighting retrofits and three-phase service questions come up constantly. A contractor who works both sides needs a different set of habits for each, and the service list here reflects that split.
On the residential side, the published range covers new construction wiring, system upgrades, renovations and additions, repairs, troubleshooting, panel replacement, EV charger installation, generators and lighting. That is the full spread rather than a narrow specialty. Panel replacement is worth calling out because it is the job most Newark homeowners eventually face: an old fuse box or a crowded Federal Pacific-era panel with no room for the circuits a modern kitchen needs. Upgrading the service usually means coordinating with PSE&G on the meter and drop, pulling a permit through the city, and getting an inspection signed off before the work is closed up. Ask directly who files the permit and who schedules the inspector, because that is where jobs stall.
Commercial work is listed separately, covering new construction, system upgrades, renovations, repairs and what the company calls specialty services. For a small business in Newark, the practical questions are turnaround and paperwork. A restaurant on Ferry Street waiting on a fit-out sign-off cares less about hourly rate than about whether the electrician shows up when the inspector does. The crew at D M Master Electric L L C presents itself as handling planning and assessment up front, with clear communication through the job, which is the right pitch for that kind of scheduled work even if you should still get scope and exclusions in writing.
EV chargers and generators are the growth areas across Essex County, and both are more involved than they sound. A Level 2 charger in a Forest Hill driveway may need a load calculation and sometimes a service upgrade before the circuit can be added at all. A standby generator brings in a transfer switch, gas line coordination and a separate permit. If either is on your list, ask what the panel can actually carry before you buy hardware.
Coverage is broad. The site lists every Newark ward plus East Orange, Irvington, Bloomfield, Montclair, Maplewood, Millburn and Livingston in Essex, then Jersey City, Hoboken, Bayonne, Kearny and Harrison in Hudson, and Elizabeth, Linden, Union, Rahway and Westfield in Union County. Travel across that footprint in weekday traffic is real, so confirm arrival windows rather than assuming same-hour service just because the phone is answered.
The reviews are the clearest evidence available. A 5 out of 5 average across 262 Google ratings, read on September 30, 2026, is unusual volume for a local electrical contractor, and the absence of a long tail of low scores suggests consistency on both small repairs and larger installs. That said, review averages tell you about experience, not about price, and a review cannot confirm a licence. New Jersey requires electrical contractors to hold a state business permit and licence number, so ask for it and check it, as you would with anyone.
Who it suits: homeowners facing a panel or service upgrade, buyers with an inspection punch list, landlords with recurring faults across units, and small commercial clients needing renovation wiring with permits handled. Who it may not suit: anyone shopping purely on the lowest hourly rate, or someone wanting a single specialist trade such as low-voltage networking only. Against the alternatives in the market, D M Master Electric L L C sits between the one-van operator, cheaper but often booked out for weeks, and the larger regional firms with dispatch fees and flat-rate pricing books. Before booking, get the quote in writing, confirm whether the visit carries a diagnostic charge, ask how after-hours calls are priced against daytime work, and check that the final inspection is included in the number you are given.

D & M Master Electric L.L.C. FAQs
Does D & M Master Electric really answer calls at night?
Its published hours are 24 hours a day, every day of the week, so an overnight call is worth making. Hours listings reflect phone availability rather than a guarantee that a van is dispatched immediately, so describe the problem clearly and ask what the emergency response time and after-hours rate look like before agreeing to a visit.
What areas does it cover around Newark?
All of Newark plus a wide stretch of northern New Jersey. The website lists the Central, North, South and East wards along with Downtown, University Heights, Forest Hill, Vailsburg, Clinton Hill, Weequahic and both Broadways, then Essex County towns including East Orange, Bloomfield, Montclair, Maplewood, Millburn and Livingston, Hudson County from Jersey City and Hoboken through Kearny and Harrison, and Union County including Elizabeth, Linden, Rahway and Westfield.
How good are the reviews?
The Google Business Profile showed a 5 out of 5 rating from 262 reviews when read on September 30, 2026. That is a high count for a local electrical contractor and points to consistency, though reviews say nothing about pricing and cannot verify licensing or insurance.
Can it upgrade an old fuse box or 100 amp service?
Yes, panel replacement and system upgrades are listed as core services. In Newark this type of job normally involves a permit through the city, coordination with the utility on the meter and service drop, and an inspection before the work is signed off. Ask who handles the permit and inspection scheduling, and whether those costs are inside the quoted price.
Does it install EV chargers and generators?
Both appear on its service list. For a home charger, expect a load calculation first, since some older Newark and Essex County services cannot take an additional 40 or 50 amp circuit without an upgrade. Standby generators add a transfer switch and, for gas units, fuel line coordination, so confirm the full scope in writing.
How do I get a price from d m master electric l l c?
Call (973) 604-5628 or use the quote form on its website, which asks whether the job is residential, commercial or lighting plus a short description. The company advertises free quotes. Ask for the estimate in writing with materials, permit fees and inspection included or clearly excluded.
