Local focus

Brockville's mix of heritage homes along the St. Lawrence and newer residential developments creates varied electrical needs. Panel upgrades are common in the older downtown core, while new builds in the surrounding area need full electrical packages with modern code requirements like arc-fault protection and EV charger pre-wiring. We travel to Brockville for projects that justify the mobilization and coordinate scheduling to keep costs reasonable.
