Melvin and his team initially came to fitted a new skylight for us - they knuckled down, worked hard in tough conditions and were always polite and tidy. So much so that I have since invited them back to also fitted us a new front door and a new electrical consumer unit (that was subcontracted to an NIC qualified electrician who was very good too). Melvin is very reliable and clearly is a thinker, which is refreshing. Highly recommended.
