Qamil He constructed our loft conversion, which we more than happy with. He paid attention to detail and followed the drawings by the architect precisely.He was always willing to discuss any issues and communicate his next plans for the ongoing work. As he was hardworking and punctual the work was done to programme. Would highly recommend him and all the sub-contractors that he has used. Tracey and Andy Sparks

Previously I worked for housing developers doing and managing the construction and finishing of the buildings and after many years working for someone else and gaining wider experience I choose to start my own business.

Nicolae was punctual, knowledgable and tidy! He tried to identify a leak (turns out the problem may be the washing machine rather than a problem with pipes). He helped rectify the washing machine. He tidied up after himself. Cannot fault him. I have already asked him to return to do other works in my home.
