Detached houses, condo units with shared services and small offices each carry a different set of constraints and a different set of rules. Thornhill Electrical Services works across all three in Thornhill, and our emergency electrical services take the calls where a fault has affected more than one occupant.
Our electrical estimates state clearly which part of the installation is yours and which belongs to the building, which resolves most of the argument before it begins. Homes, units and commercial electrician services across Thornhill are covered by the same crews. Where continuity matters we fit backup generator installation and solar battery backup, and design commercial backup solutions to suit.
Unit boards, common supplies and landlord circuits are traced and separated before any work is priced.
A fault touching more than one unit is urgent, and it is attended without waiting for a board meeting.
Scope, cost and responsibility set out in a document a manager can circulate and act on directly.
Inspection and certification produced in the form a corporation, a lender or an insurer will accept.
In a block or a managed building, the board in your unit is only part of the installation you depend on, and usually the only part anybody has documented.
Tracing the supply and setting out ownership in writing prevents you paying for cable that belongs to the corporation.
Units carry work from several occupiers, none of it recorded. Testing tells you honestly what can safely remain.
Specifying metering properly means a charger draws on your supply rather than quietly on somebody else's.
Lifts and life safety circuits have their own requirements, tested under load and recorded in the form a corporation expects.
Most repeat faults come back because the symptom was replaced and the cause was never found. Property owners in Thornhill use Thornhill Electrical Services for electrical repair, covering fault tracing, testing under load, terminations, and lasting fixes.
Tandem breakers filling a board are a sign the service is already at its limit, not a clever use of space. Homeowners in Thornhill use Thornhill Electrical Services for panel upgrades, covering demand recording, service sizing, bonding, and inspection.
A licence is what makes the certificate at the end of the job worth anything to anybody else. Property owners in Thornhill use Thornhill Electrical Services for a licensed electrician, covering individual licensing, insurance, testing, and documentation.
Running an extension lead permanently is a sign the room is short of outlets, not short of leads. Homeowners in Thornhill use Thornhill Electrical Services for outlet installation, covering new circuits, cable routes, box mounting, and testing.
Machinery that starts sluggishly or trips on load is usually starved by its feed rather than worn out. Businesses in Thornhill call Thornhill Electrical Services for equipment wiring, covering feeders, disconnects, motor starters, controls, and commissioning.
A charger draws continuously for hours, which is a very different demand from anything else in the house. Property owners in Thornhill use Thornhill Electrical Services for charger installation, covering capacity checks, dedicated circuits, permits, and inspection.
In a shared-service building the board is only half the story, so what belongs to you and what to the building is settled first.
A fault affecting more than one unit is urgent by definition, and after hours the call reaches an electrician rather than a recording.

Inspection and certification are produced in the form a corporation, a lender or an insurer will take without a follow-up.
Circuits are traced and the board documented at completion, so nobody starts from nothing on the next visit.

Don't see your area listed? We likely still serve you — just ask.
Yes. Every service change needs an electrical notification filed and an inspection booked before the work is signed off, with no exceptions for like-for-like swaps. We file the notification within 1 business day of your approval, schedule the inspector, and hand you the Certificate of Acceptance at close-out. Keep that certificate, because it is the document your insurer asks for when you renew.
Most attached-garage installs land between $900 and $1,800, and the two things that move the number are the length of the cable run and whether your panel has a free double-pole slot. A ten minute load check tells us which end of that range you are on. You get a fixed written price before any work starts.
Usually. We hold same-day slots every weekday for no-power calls, burning smells, and breakers that will not reset, and an electrician is on call after 10PM for genuine emergencies. If we cannot reach you the same day we will tell you when you call rather than after you have waited. Booked work such as panel upgrades is typically scheduled within 5 to 10 business days.
Every job carries 2 years on our labour plus the manufacturer warranty on any panel, breaker, or device we supply, which usually runs 1 to 10 years depending on the part. The terms are printed on your invoice rather than buried in a policy document. Thornhill Electrical Services honours that labour warranty regardless of which of our electricians did the original work.
Regularly, and it is one of the most common reasons property owners in Thornhill call us. We can replace the wiring in stages if the budget calls for it, starting with the circuits insurers flag first, and we provide the documentation and certificate they require before renewing. Most full-house rewires run 3 to 5 working days depending on the number of circuits and whether the walls are open.
Three signs matter most: a service rated at 60 or 100 amps, a panel with no spare breaker slots left, and breakers that trip when two ordinary appliances run together. Any fuse panel, or any panel carrying a recalled brand, should be assessed regardless of how it is behaving. We run a load calculation across Thornhill properties and tell you honestly whether an upgrade is needed or whether a subpanel solves it for less.
A standard 100 to 200 amp service upgrade is a single day on site, and your power is off for roughly 4 to 6 hours of that while the service is swapped and terminated. We give you the shut-off window the day before so you can plan around fridges, freezers, and any work-from-home commitments. The inspection is usually booked within 2 business days of completion.
Every electrician on our crews holds a valid licence, and the company carries $5 million in liability coverage plus full WSIB clearance. We subcontract nothing, so the person who quoted your job is the person on your property doing it. Thornhill Electrical Services can send current copies of the licence, insurance certificate, and WSIB clearance before we start if you would like them on file.
