Editorial Review
Our Take on JM Electric Inc.
The review volume here is the strongest signal: 773 ratings at 4.9 is a lot of completed jobs, and it lines up with a company that has been working the same metro since 1994. The service list reads like a genuine residential book of work rather than a keyword page, particularly the panel brand replacements and the detector replacement cycle. Ask about after-hours rates and permit handling before booking, since neither is spelled out publicly.
Best for: panel upgrades and EV charger installs in Denver metro homes
What We Like
- 4.9 stars from 773 reviews on its Google Business Profile, read September 28, 2026
- Trading since 1994 according to its own website, with a family-owned structure
- Strong focus on code-sensitive work: panel replacement, EV circuits, rewiring, hot tub wiring
- Service area covers Aurora, Denver, Westminster, Littleton, Centennial, Arvada and Englewood
- Free in-home estimates and financing advertised, plus an optional annual membership plan
Things to Consider
- Published 24 hour availability is not the same as a technician on site overnight; confirm after-hours response and rates
- No prices are published beyond the $120 annual membership plan, so estimates need to be obtained job by job
- Public material leans residential, so commercial clients should confirm scope directly

About JM Electric Inc.
Residential electrical work in the Denver metro tends to cluster around a few predictable jobs, and jm electric inc covers most of them. Panel installation and repair sits near the centre of the offering, including replacement of Zinsco and Federal Pacific panels, two brands that have been flagged for decades and that still turn up in houses built through the 1960s and 70s across Aurora and the older Denver suburbs. Breaker replacement on panels that are otherwise sound is offered as an alternative to a full swap, which is a sensible distinction to make and one worth asking about before you agree to the larger job.
EV charging is the other growth area, and the company says it handles Tesla Wall Connectors and other Level 2 units, along with the permitting and any panel capacity work the install requires. That last part matters more than people expect. A 100 amp service in a mid century Aurora ranch often will not carry a 48 amp charger alongside an electric range and central air without either a load calculation that proves it or a service upgrade, and a good electrician tells you that during the estimate rather than after the equipment is on the wall.
Beyond those two, the list runs through hot tub wiring with dedicated GFCI protected circuits, ceiling fan mounting, recessed and pendant lighting, outdoor and security lighting, whole home surge protection at the panel, safety inspections, and rewiring for remodels or whole houses. Troubleshooting and repair is listed on its own, which is the category most people actually call about: a dead circuit, a breaker that keeps tripping, an outlet that gets warm. Smoke and carbon monoxide detectors are treated as a scheduled replacement item, on the ten year cycle the manufacturers specify, and that is the kind of detail a contractor only bothers mentioning if they do the work regularly.
The family-owned framing and the 1994 start date both come from the company's own website. Longevity is not a guarantee of anything, but a contractor still trading after three decades in a market as competitive as Denver has usually worked out its scheduling and its warranty handling. The published Google rating of 4.9 from 773 reviews, read on September 28, 2026, backs that up in volume more than in any single detail. Reviews at that scale are hard to manufacture and usually reflect a high job count over many years.
Who it suits: homeowners in Aurora, Denver, Westminster, Littleton, Centennial, Arvada and Englewood who want a licensed and insured crew for permit-bound work. The company advertises free in-home estimates, which is the normal arrangement for install work in this market, and it offers financing plus an annual membership plan at a stated $120 a year that includes a discount on services, an extended warranty window and a yearly panel inspection. Whether a plan like that pays for itself depends entirely on how much work you expect to have done, so treat it as a question rather than an assumption.
Who it may suit less: anyone hunting the cheapest possible price on a single small task. A larger residential outfit with a dispatch operation, a review base in the hundreds and a membership program is not usually the lowest bid on a two outlet job. Commercial clients should confirm scope directly, since the public-facing material leans heavily residential even though the business describes itself as covering both.
Denver's permitting adds a layer worth understanding. Panel upgrades, service changes, EV circuits and most rewiring need a permit and an inspection, and jurisdiction matters: Aurora, unincorporated Arapahoe County, Denver proper and Jefferson County each run their own process. Ask who pulls the permit, who meets the inspector, and how long the wait is running, because in busy periods the inspection queue, not the wiring, is what sets the finish date. Also ask about Xcel Energy coordination if the meter or service drop is involved, since that can add its own scheduling step.
The hours listed on the Google profile show 24 hours, every day, and the company markets emergency service. Confirm before you call late whether that means a technician on the road or an answering service taking details until morning, and ask what after-hours labour costs. Get the warranty terms in writing too, covering both labour and the parts, and clarify whether that coverage moves with the house if you sell.

JM Electric Inc. FAQs
Where is JM Electric Inc. based and which areas does it cover?
The business operates from 700 Billings St Ste R in Aurora, CO 80011. Its website lists a service area covering Denver, Westminster, Littleton, Centennial, Arvada and Englewood alongside Aurora, so most of the metro is within its stated range. Confirm coverage for outlying addresses when you book.
How is jm electric inc rated?
Its Google Business Profile showed 4.9 stars from 773 reviews when read on September 28, 2026. That is a high average across a large sample, which usually reflects a long run of completed residential jobs rather than a short burst of feedback.
Does it handle EV charger installation?
Yes. The company lists Level 2 charger and Tesla Wall Connector installation, and says it handles permitting and any panel work the circuit requires. Expect a load calculation first, because many older Denver-area homes on a 100 amp service need a capacity check or a service upgrade before a high-amperage charger can be added.
Is it really available 24 hours a day?
The published hours on the Google profile show open 24 hours, seven days, and the company markets emergency electrical service. Ask directly whether a late-night call brings a technician out or is logged by an answering service until morning, and ask what the after-hours labour rate is before agreeing to a visit.
What does the membership plan include?
The website lists an annual plan at $120 that offers 10% off services, an extension of warranties from one year to three from the install date, and a free panel inspection once a year. Whether it is worth taking depends on how much electrical work you expect over the next few years.
How long has the company been in business?
Since 1994, according to its own website, which also describes it as family-owned. That gives roughly three decades of trading in the Denver and Aurora market, though the claim comes from the company rather than an independent record.
Will I need a permit for a panel upgrade?
Almost certainly. Panel replacements, service changes, EV circuits and most rewiring require a permit and inspection in Colorado, and the process differs between Aurora, Denver, Arapahoe County and Jefferson County. Ask who pulls the permit, who meets the inspector, and whether Xcel Energy coordination is needed for meter or service work.
Is JM Electric Inc. licensed and insured?
We have no credential records on file for this company yet. Ask for the certificate directly from the insurer before booking work.
What areas does JM Electric Inc. serve?

Does JM Electric Inc. offer emergency service?
Emergency availability is not listed for this company. If you need an urgent call-out, check the ranking for companies that do list it.
What warranty do they offer?
