Electrical- 17 May 2017
Andrew of Kaldien was very quick to respond to my job. He went out of his way to visit our home out of working hours. He found the fault very quickly and luckily we only had to incur the call out charge which included half an hour's labour. The fault is up and running again and we couldn't be happier with his work. Will definitely be using Andrew again.
