First used them to install our solar panels and were so impressed with the service we received that we have called them again for fixing some dodgy wiring to our lights.
They were able to give a short window of time (15 min) for arriving to do the work but also called the evening before to let me know they would be half an hour later. They then arrived ON time and completed the work in a reasonable time frame. i found them very easy to deal with, they were very happy to have my young children watching them work and talked them through some of the things they were doing.

Approximate cost: $6000
