Electrical Work in Mortdale
Mortdale sits between Penshurst and Oatley on the Illawarra line, with a village shopping area near the station and established residential streets around it.
Many homes are brick houses from the middle of last century, some renovated and some largely original. That makes switchboard upgrades and partial rewiring common requests.
We explain the condition of the installation plainly and recommend work in a sensible order.
