HIRE HIM AT YOUR OWN RISK!Unprofessional and unreliable!!
I highly doubt Muhammad hold any certificate/skills for the job he is doing. I was actually not going to hire him for the job as my gut feeling was telling me not to. He had previously installed a toilet that I was not entirely happy with. But Muhammad was calling me everyday saying how he had no job, his mortgage not going to go through as he had no money. I fell in the trap and hired him. The job meant to take a week to install a shower and tile the bathroom took 2 months. He started the job very well but after 2 days it was by his terms. He would come in the evenings fit two tiles here and there demand payment and leave. I felt so powerless he had already started the work, if I stopped him it would mean i would mean a fresh quote costing more so I did not have a choice but to stick with him. In addition he would ask me to by all the equipment e.g drills he used so numerous trips to screw fix costing much more. The worst after the tiles started cracking while he was still on site so he was repairing the tiles while completing the other tiles. For example he had left the space on top of window and behind the doors with no tiles so I discovered this when he was saying 'all done " and crying on the phone I pay his money. Worst of all half of the bathroom tiles have cracked and the shower/sink he fitted is leaking downstairs causing more damage.He has refused to respond to resolve the issue.Can only wish you good luck.
