I engaged CSJ on A family members recommendation and had long delays, fortunately my 8-week job only took 28-weeks. I have delayed my review so that it's publication would not jeopardise my family finally getting their job completed. The completed job an extension to a dinning room and kitchen together with a new kitchen. My biggest complaint starts with the CSJ contract. This A3 "yellow" piece of paper is not sufficient to detail anything that is not a major element of the build ( e.g. Flooring, tiling , taps sink etc) so if you get into a contract with CSJ get a complete schedule of work detailed down to the n'th degree. My job was a 10% deposit and two staged payments of 30% with a final 30% on completion. What I found out was that CSJ would rush work so as to achieve a payment stage. For example, the plasterer was rushed and the finished job is woeful. The other work done by the plasterer was fine so it is not the workmanship, it is CSJ's pressure on their staff. I am sure that CSJ are great at their core work (I.e fitting Windows), but they seemed lost at the bigger extension work. In the spirit of fairness, apart from the plastering which looks like the surface of the moon I am content with the finished extension, but it needed a lot of work from me and my wife to achieve this. For example, they mixed up components from my family members job bringing their sink, without our intervention they would have cut the worktop incorrectly.
