Circuits added without a permit across Markham rarely match the load they carry.
Markham Electrical Services spent its first years fixing what other people had installed across Markham. Doing that long enough teaches you exactly what not to do when installing something yourself.
One van and a meter, called to failed terminations, buried junctions and circuits that had been extended twice without record.
ECRA/ESA registration brought permits and certification in-house, so nothing we touched was left undocumented afterwards.
Panels, chargers and standby systems, specified for service life because we had spent years replacing things that were not.
Old cable removed rather than abandoned, terminations torqued, and conduit left in place for whatever gets added next.
In older property the making-good frequently costs more than the electrical does, so routes are surveyed before anything is cut and the plaster, trim and joinery come through intact.
Households across Markham keep adding equipment to boards that were full years ago. Our mission is to make the service underneath honest again, so a new appliance is an addition rather than the start of a tripping problem.



A full board is a decision waiting to be made, and these are how we make it:

From one dead outlet to a whole-house rewire, Markham Electrical Services handles diagnosis, permit, installation and inspection in-house. That includes EV charger installation, backup generator installation, whole home surge protection and pot light installation.

Circuits found without a permit behind them are tested and corrected rather than energised and passed to the next owner.
Across Markham, Markham Electrical Services is asked to add chargers, heat pumps and finished basements, and the first question is always what the existing service can actually carry.

Two years on our labour, plus manufacturer cover on parts, printed on the invoice where you can actually find it later.
If the work is not needed we say so. If it is more than you were told, we say that too, before anything is opened up.
Routes planned before anything is cut, plaster and trim protected, and the whole area cleaned each evening.
What you should know before booking Markham Electrical Services
Yes. Markham Electrical Services holds contractor licensing and every electrician holds an individual licence, which is why our inspections pass and our certificates are accepted.
Both, with one team, covering panel upgrades, rewiring, EV chargers and standby generators for households, pot lights and lighting retrofits throughout, and full commercial distribution across Markham.
Across Markham and every community on the service area page. Rural property is ordinary work here rather than a job we would rather avoid.
No. The survey costs nothing and it is what makes the figure accurate, because access and meter position decide far more of the price than materials do.
For your job, yes. One person from first look to certificate, with no subcontracting at any point.
Our labour for two years, the equipment by its manufacturer. Markham Electrical Services prints both on the invoice and returns free of charge if something is wrong.
Ask Markham Electrical Services about capacity, panel upgrades, charger circuits or standby power anywhere in Markham.
A board full of tandem breakers is already at its limit. Knowing that first saves buying equipment you cannot run.
