Kay removed an under-stairs WC, decommissioned a radiator, moved a radiator and powerflushed the central heating system. Some of this involved him having to crawl under the floor to weld joints - a very dirty job. Throughout, Kay was highly professional and identified matters which should be addressed urgently or which would affect the performance of the system. He was also able to arrange some internal building works at very short notice, for which we were very grateful. Kay was friendly, helpful, flexible and accommodating throughout and we would certainly use him again.
