Older homes in Unionville and Markham Village may still have knob-and-tube wiring or 60-amp services. In homes built from the mid-1960s through the late 1970s, we handle aluminum wiring remediation and replacement. ESA identifies this period as the one most commonly associated with residential aluminum wiring. In newer Cornell and Box Grove developments, common projects include EV charger circuits and 200-amp upgrades.
