What we wire on a new build
Rough-in wiring
Circuits, boxes and the panel feed, before the insulation and drywall go on.
Underground service to the house
Some lots come in underground and some come off a pole. We do both, and we dig it ourselves.
Panel, meter base and service entrance
Set, installed, labelled and ready for inspection.
Trim-out and finish wiring
Devices, fixtures and plates, everything tested, and a walk-through before it is called done.
Generator and EV charger rough-in
On the plan? Tell us now. Pulling the wire while the walls are open means nobody has to cut them open later.
Cottages, waterfront and hard sites
Rock, water and distance. That is the normal week here.

What we do
Four new builds in Grey Bruce
Our jobs, our photos. Tap a photo for the crew’s own words.
Wired from the ground up
Panel first, circuits roughed in, then tied in clean and labelled.
“This new build in Cape Croker is wired by our team from the ground up.”
Rough-in and service
A full site visit with the owner first, then the rough-in.
“Before starting, we did a full on-site consultation with the homeowner to go over every detail. Once on-site, we roughed in all wiring, tied everything in, and performed a final walk-through.”
60 metre trench, one day
A new 200 amp underground service in, and the ground closed back up.
“Progress in Sauble Beach! In just one day, our crew dug a 60m trench, installed a brand-new 200 amp underground service for this new build, and closed it back up.”
A new 1,800 square foot home
The wiring on a new home, from the start.
“Wiring up a beautiful 1800 square foot home in Hepworth, Ontario.”
Electrician reviews, Owen Sound and Grey Bruce
Road to panel. Their words.
“They installed a new Generac system and did a remarkable job. Dunne was the prime vendor who co-ordinated and managed all the players involved such as the gas professional and Hydro One to name a few.”
Ron J.Google review, August 2026
“They are very informative, prompt with services and did a great job installing my new panel for new hydro services. I will definitely hire them again for any further electrical work.”
Elijah N.Google review, July 2026
“From start to finish, they were professional, punctual, and incredibly efficient. Communication was excellent throughout the entire job, and they kept us informed every step of the way.”

What decides the price
- Square footage and the number of circuits
- Service size
- Overhead or underground
- How far the service has to run
- What is in the ground
- Heat type
Tom does the estimates himself, off the drawings, so the number is for your house and not a range off a website. He will tell you what he needs to price it.
“Dunne power from the moment I called was professional, transparent about pricing, fair and provided exceptional work.”

Call 519-373-2543Do you wire the whole house, or just the panel?
The whole house. Trench and underground service, meter base, panel, rough-in, then back for the trim-out. Cape Croker was wired by our team from the ground up. Tobermory was rough-in, service and a final walk-through.
Do you dig the trench, or do I need somebody else for that?
We dig it. Bucket trucks and an excavator in the yard, so pole work, trenching and underground services are done by our own crew. In Sauble Beach the crew dug a 60m trench, put in a brand new 200 amp underground service for a new build and closed it back up in one day.
How far do you go?
Tobermory to Walkerton, across Grey County, Bruce County and the South Bruce Peninsula. Our new builds have been in Hepworth, Tobermory, Cape Croker and Sauble Beach. Not on the list? Call and ask.
Can you wire a lot on rock, across the water or a long way from the road?
Yes. That is most of the peninsula. On a 2025 island build the main service went into solid bedrock and the crew chipped through rock and concrete by hand, with the concrete hand-loaded to the van, then the boat, then across the island to a 100 ft bedrock trench. Tell us what the site is like and we will tell you what it means for the service.
Are you licensed and insured?
ESA Licensed Electrical Contractor and WSIB covered. Every job gets the permit and the inspection. Member of the Grey-Bruce Home Builders and Trades Association, and Platinum Electrician in the CommunityVotes Grey County 2025 vote.
Who will I actually be dealing with?
Tom does the estimate. The crew does the work. The office answers the enquiry.
What does it cost?
It depends on the size of the house, the service, and how the power gets to the lot. We would rather look at the drawings and give you a real number than publish a range that does not fit your build. Call 519-373-2543 and tell us about it.
