Dalgleish Enterprises Pty. Ltd. trading as E.R.A. Contractors, a dynamic organisation, is currently enjoying significant growth, much of which is a direct result of numerous challenges presented by the isolation of the Pilbara and Gascoyne region, tourism and the progressive nature of the many resource-based companies operation in the region.

E.R.A. Contractors commenced trading in May 1991 and was owned by Chillair Services Pty Ltd. Dalgleish Enterprises Pty Ltd purchased the company in October 2006. Initially trading from a leased residential / commercial lot in the Onslow town site, the company offered only refrigeration / air-conditioning installation and maintenance services. Since 1993 however, a major portion of the Company’s work has been sourced from the provision of electrical installations and maintenance services including but not limited to fire breaks and ground control.

Our Head Office is now located at 37 Koolinda Way, Exmouth. E.R.A. Contractors is ideally located to provide Electrical, Refrigeration and Air-conditioning installations, repairs and maintenance services to commercial, tourism, fishing, oil and gas exploration and production-based companies in both the Gascoyne and Pilbara regions.
