Switchboard Upgrades
Older switchboards are common in Oyster Bay's established homes. We upgrade them to modern circuit breakers and safety switches, which also protects the extra outdoor and pool circuits many waterfront properties carry.

Oyster Bay · NSW 2225
Oyster Bay sits on a finger of land between the Woronora River and Georges River, with a large share of properties backing onto water or bushland reserve. The mix here runs from older brick homes on the higher streets to renovated split-level houses closer to the foreshore, many with decks, pontoons or boat sheds that need their own outdoor power and lighting.

Electrical Work in Oyster Bay
Oyster Bay sits on a finger of land between the Woronora River and Georges River, with a large share of properties backing onto water or bushland reserve. The mix here runs from older brick homes on the higher streets to renovated split-level houses closer to the foreshore, many with decks, pontoons or boat sheds that need their own outdoor power and lighting.
Because a lot of Oyster Bay is close to the water, salt air and humidity take a toll on outdoor electrical fittings faster than they would inland. We see a steady run of outdoor power points, deck lighting and switchboard work here that's really about replacing fittings that have corroded rather than a fault in the wiring itself.
We're based in Kirrawee, close enough to Oyster Bay to give a realistic on-site time for most jobs. Whether it's a straightforward power point addition or a full switchboard upgrade ahead of a renovation, we scope the work around the specific property and the conditions it sits in.

Additional power points, USB outlets and kitchen or laundry circuit upgrades for renovations, a common job in Oyster Bay's split-level and split-front homes.
