I would not recommend this tradesperson. He said the job would take about 3 days and he would start the following week but then disappeared for 3 weeks and wouldn't respond to my calls. When he eventually did finish it wasn't finished well and he hadn't connected the pipes correctly to the sink or the washing machine. Biggest problem was when the toilet started to leak we couldn't get it repaired because he had siloconed it to the floor and to the wall as well as the top tank to the bottom bowl. Disaster!
