Steel & Tube
We used Custom Electrical for the refurbishment and upgrade of Gilmours Manukau. Kiauni, the site manager from Custom Electrical was outstanding. We had no call backs or call outs on this project which is very uncommon for this type of work as Gilmours needs to continue operating while the project is being carried out.
