/ Frequently Asked Questions
Electrical Questions, Answered Clearly
How much does a licensed electrician near me cost for a service call?
We charge a flat-rate diagnostic fee of $350 for service calls across Toronto and the GTA. This covers travel and expert troubleshooting required to identify your electrical issue. Once diagnosed, we provide a clear written quote before any repairs begin.
Do you handle ESA permits and inspections for panel upgrades?
Yes. For major projects, including 200 amp panel upgrades and EV charger installations, we manage the ESA process, pull permits, coordinate with local utilities like Toronto Hydro or Alectra, and help ensure you receive your Certificate of Inspection.
Can I install a Level 2 EV charger if I only have a 100A service?
It depends on your home’s current electrical load. Our electricians perform a load calculation during the visit. If capacity is limited, we may recommend a panel upgrade or a smart load-sharing device to safely support your Tesla Wall Connector or other Level 2 charger.
How long does a full home rewire or panel replacement take?
A standard electrical panel replacement usually takes 4 to 8 hours, with temporary power disconnection. A full home rewire, common in older Toronto homes with knob and tube wiring, can take 3 to 7 days depending on property size and accessibility.
What is the warranty on your electrical services?
Sparky Electrical Services provides a 2-year labor warranty on installations and repairs. Combined with liability insurance coverage, your property is handled with care by licensed electricians.
Do you offer financing for larger electrical projects?
Yes. For larger upgrades such as aluminum wiring remediation, emergency panel changes, or major electrical projects, flexible third-party financing through Financeit may be available.
