Who are the best electricians in Hamilton in 2026?

The best electricians in Hamilton in 2026 are Pro House Maintenance, Stack Electric and Electric Safe. McGinty Toman, Kraun, Kirsch, Kiedan and Remarkable Group complete the top eight. The ranked firms hold 4.9 or 5.0 Google ratings from 151 to 278 reviews, and each has an active ESA licence.

1. Pro House Maintenance: best for comparing vetted electricians for free

Pro House Maintenance is a free way for Hamilton homeowners to compare licensed electricians. We match you with several pros who have passed ESA licence, WSIB, insurance, reference and background checks, and you compare their written quotes. You decide who to hire, and our satisfaction guarantee backs the work. It ranks first because the checks are done for you.

Old wiring jobs are where the licence check matters most. Of the 37 local firms with strong Google ratings in our search, one had no readable website and 8 were not matched to an active ESA licence by phone, website or name. We confirm the licence before any match, so a rewire starts with a licensed firm.

What we check before a electrician joins our network
  • Trade licences. We confirm an active ECRA/ESA licence. Ontario does not allow anyone to run an electrical contracting business without one.
  • WSIB clearance and liability insurance. We confirm a current WSIB clearance and commercial general liability insurance before a pro joins our network.
  • Reviews and references. We read public reviews and speak with past clients before a pro is accepted, looking for patterns, not one-off complaints.
  • Background checks. We run background checks before a pro is matched with homeowners, because the people in your home matter as much as the work.

How much does rewiring an older home cost in Hamilton?

Rewiring a small Ontario home with knob and tube wiring costs $8,000 to $12,000, and a mid-size home costs $12,000 to $18,000, says a 2026 guide from Kolji Bros. Electrical. A 100-amp to 200-amp panel upgrade costs $2,500 to $4,500, based on a 2026 Ontario guide from Wilson Electric.

ESA says knob and tube wiring is safe when a licensed contractor maintains it. Insurers see it another way: many will not cover or renew homes that have it.

How do you choose an electrician in Hamilton?

Choose a Hamilton electrician by checking for an active ESA licence first, then WSIB clearance, insurance and a written contract. Without that licence, no one can legally run an electrical contracting business in Ontario. You also have to get any building permits a job needs, so ask the city before work starts.

  1. Check the licence. Ontario law says no one can run an electrical contracting business without an ESA licence. Look up the licence number on ESA's Contractor Locator.
  2. Confirm WSIB clearance. Ask for the company’s WSIB account number and confirm a current clearance on WSIB’s free eClearance lookup.
  3. Ask for proof of liability insurance. A certificate of commercial general liability insurance should name the company that will do the work.
  4. Check the city licence. Hamilton says all contractors must hold a valid Trade and Contractor Licence, including roofers and other building repair, plumbing, drain and HVAC contractors. Search the City of Hamilton licensed contractors list.
  5. Get it in writing. Under Ontario law, any home renovation contract worth more than $50 must be in writing, and the final price cannot exceed an estimate by more than 10% unless you agree (Ontario consumer protection rules).
  6. Keep the deposit small. Ontario recommends a down payment of no more than 10%, and never paying in full before the work is done.

Ontario puts it plainly: “It’s your responsibility to get building permits and meet any legal requirements you’ll need to renovate.” Your electrician files the ESA permit for the wiring. A city permit for a second unit or an add-on is a separate step, so ask early.

Pro House Maintenance confirms the ESA licence, WSIB clearance, insurance and references before a match. A second unit needs more than wiring, so you can also book vetted handyman services in Hamilton for doors, trim and drywall.

How did we rank these Hamilton electricians?

We ranked these electricians on data, not ads. Our Google Maps searches for electricians found 120 businesses across Hamilton and Stoney Creek. We kept 37 local firms with a website and 4.5 stars from 10 or more reviews, then ranked the 28 with a readable website and an active ESA licence by review-weighted rating.

ESA licensing is a hard gate for this trade. ESA’s public registry held 18,642 contractor records, and 346 showed a valid licence with a Hamilton-area address. Eight of the 36 rated firms with readable websites were not matched by phone, website or name. A pick also needs a working website, which ruled out one firm.

The score blends rating and review count, which is why McGinty Toman’s 5.0 from 156 reviews ranks above Kraun’s 4.9 from 185. We checked each fact on October 2, 2026, and recheck the list every 90 days.

Facts marked “company website” come from each firm’s own pages, with exact quotes kept on file. If something is wrong, please send our team a correction.

What do Hamilton homeowners ask before hiring an electrician?

Hamilton homeowners with old wiring, a full panel or plans for a second unit ask the same few things. The answers below use ESA's guidance, Alectra's posted rules and 2026 Ontario price guides. Each answer stands alone, so jump to the one that fits your home.

How much does knob and tube replacement cost in Hamilton?

Rewiring a knob and tube home costs $8,000 to $12,000 for 800 to 1,200 square feet, and more for bigger homes, says a 2026 Ontario guide from Kolji Bros. Electrical. A panel upgrade, which the guide says is almost always needed, adds $3,500 to $4,500.

Is knob and tube wiring safe?

Yes, if it is kept in good repair. ESA says knob and tube wiring is safe when a licensed contractor maintains it properly. The catch is insurance, since many insurers will not cover or renew homes that have it. ESA suggests a licensed contractor check the wiring, which is not the same as a home inspection.

How much does a panel upgrade cost in Hamilton?

A 100-amp to 200-amp upgrade costs $2,500 to $4,500, and a 60-amp to 100-amp upgrade costs $2,000 to $3,000, says a 2026 Ontario guide from Wilson Electric. ESA's own 2026 fee for a renovation with panel work and up to 10 outlets is just $105.

Does Alectra charge to disconnect power in Hamilton?

Not for one planned visit a year. Alectra, which serves Hamilton, says each residential customer gets one free planned disconnect every 12 months. On the booked date, Alectra or an approved contractor cuts the service so your electrician can work.

Is Pro House Maintenance free to use?

Yes, there is no charge to homeowners. We match you with several Hamilton electricians who passed ESA licence, WSIB, insurance, reference and background checks, and you compare their written quotes. You choose, and our satisfaction guarantee backs work from an electrician we match you with.

Where can you find electricians near Hamilton?

The closest electricians lists to Hamilton cover Burlington (10 km away), Milton (29 km away) and Mississauga (41 km away). Each list follows the same method: 4.5-star Google ratings from 10 or more reviews, official registry checks where Ontario requires a licence, and free vetted matching from Pro House Maintenance at number one.
