Adding load? Ask Markham Electrical Services about electrical services and headroom in Markham.
Chargers, heat pumps, panels full of tandem breakers and finished basements added without a permit are the common thread in most of our calls. Markham Electrical Services corrects and future-proofs that across Markham, and our emergency electrical services cover what happens when an old service is finally asked for too much.
Capacity is calculated first, then electrical estimates, then installation, so nothing is fitted onto a service that cannot carry it. Homes, offices and commercial electrician services across Markham follow the same order. We also install backup generator installation and solar battery backup, and integrate commercial backup solutions with what is already on site.
A charger on a full panel will trip forever. Capacity is confirmed before anything is quoted, let alone installed.
Dead circuits, hot panels and scorched devices are attended immediately, including outside working hours.
Equipment, circuit, permit and inspection quoted together so nothing appears afterwards as an extra.
Certified and recorded, which is what an incentive programme or an insurer will ask you to produce later.
A board filling up with tandem breakers is not a quirk, it is a service already at its limit. Everything you might want to add next depends on fixing that first.
Sizing for what you intend as well as what exists means the board is not outgrown again within a couple of years.
Circuits added without a permit rarely match the load. Testing and correcting them is better than energising and hoping.
Confirming real headroom before installing is the difference between a charger that works and one that trips for years.
Permit, inspection and certificate handled together, which is exactly the documentation an incentive programme will later ask for.
Most repeat faults come back because the symptom was replaced and the cause was never found. Property owners in Markham use Markham 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 Markham use Markham 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 Markham use Markham 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 Markham use Markham 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 Markham call Markham 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 Markham use Markham Electrical Services for charger installation, covering capacity checks, dedicated circuits, permits, and inspection.
A panel filled with tandem breakers is already at its limit, so available capacity is verified before a charger or a heat pump is quoted.
A board running warm or a scorched device is attended immediately, because those are the faults that turn into something worse.
Work is permitted, inspected and documented, which is exactly what an incentive programme or an insurer eventually asks you to provide.
Circuits found without a permit behind them are tested and put right rather than energised and left for the next owner to inherit.

Systems are sized from measured demand, commissioned under load and documented at handover.
The board was full of tandem breakers and I had been told that was fine. They showed me why it was not and replaced it with room to spare.
Charger, permit and inspection in one figure from Markham Electrical Services and the certificate came with the rebate paperwork already filed. Money arrived without a query.
A scorched receptacle behind the fridge that we only found because the breaker started tripping. Same-day visit and every device on the run replaced.
Our basement was finished by a previous owner with no permit. Markham Electrical Services tested every circuit, corrected what was wrong, and got it certified retrospectively.
They confirmed the capacity before quoting rather than after installing. The charger has never tripped, which apparently is not everyone's experience.
Transfer switch specified and commissioned properly by Markham Electrical Services. It has cut in three times this year and we noticed once, briefly.
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. Markham 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 Markham 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 Markham 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. Markham Electrical Services can send current copies of the licence, insurance certificate, and WSIB clearance before we start if you would like them on file.
