DB Box Upgrade across the island
DB upgrades cluster in mature estates like Tampines, Bishan and Woodlands where original boards lack proper earth-leakage protection, and are a standard part of full renovations. Jurong condo owners upgrade when adding high-load circuits, while Punggol's newer boards rarely need it. A DB upgrade is notifiable work, so ask for the EMA licence first; a good electrician handles the paperwork, tests every circuit, and shows its real Google reviews.
Pros on Homees serve every estate — including Tampines, Jurong, Woodlands, Punggol, Bishan — islandwide.
