Electrical Hot Spot Inspection in Markham

Standalone residential panel + sub-panel scan: $195–$295. Add-on to existing electrical work: $99–$150. Full whole-house electrical thermal audit (panel + sub-panels + 30–50 outlet/switch scan + report): $395–$595. Pre-EV-charger panel readiness scan: $99–$199 (credited toward the install). Markham market: $150–$300 residential, $400–$1,500 commercial.

Loose breaker terminations (the #1 cause of panel fires), undersized lug connections, overloaded breakers running hot, failing breakers with degraded internal contacts, aluminum-wiring connection degradation under load, and suspect knob-and-tube remnants in older homes. Visual inspection cannot detect these — they're heat-only signatures.

No. ESA inspections are issued by the Electrical Safety Authority — our scan is a supplementary diagnostic. ESA inspections are required for permit-pulled electrical work (panel upgrade, EV charger, sauna, etc.). Thermal scans are diagnostic only, useful for insurance documentation, pre-purchase due diligence, and pre-renovation planning. We coordinate both when needed.

Yes — our thermal electrical scan is always conducted with a Master Electrician on site (RenoHouse holds Master Electrician licensing and ESA contractor license). Homeowners cannot legally open electrical panels in Ontario; only ESA-licensed personnel can. Our electrician opens the panel, our thermographer scans, and the electrician confirms findings on the spot.

Standalone panel scan: 30–45 minutes. Whole-house electrical thermal audit (panel + outlets + switches): 60–90 minutes. Pre-EV-charger panel readiness check: 20–30 minutes. PDF report delivered within 24–48 hours.

Some Canadian insurers in Markham have started flagging older electrical panels (Federal Pacific, Zinsco), aluminum wiring, and knob-and-tube as conditions of policy renewal. A clean thermal scan with PDF report can support insurance review. If problems are found, the report becomes the action plan for ESA-permitted upgrade.

We document the finding (thermal image, temperature reading, breaker label and position), advise on immediate-load-reduction actions, and quote the repair. Most loose connections can be re-torqued and verified with a follow-up scan ($99 add-on); failing breakers are replaced same-visit if we have the part on the truck (~$150–$350); panel upgrade is recommended if the panel itself is at end-of-life ($2,000–$5,000).

Limited. Our equipment (FLIR One Pro, 160×120 sensor) is at the bottom edge of acceptable for commercial / industrial thermal electrical work. For commercial buildings, multi-unit residential, or industrial panels, we recommend higher-resolution FLIR E6-XT or E8-XT equipment and ITC Level-2 thermography certification — we partner with certified providers (IRIS PDM, ThermoElite) for these jobs.
