NCM and Nick are amazing They have now become our family builders and I honestly wouldn't be able to describe in works how highly i think of them! Nick has help us rebuild our family home and looked after both of our childrens rennovations. What i would say is nothing is to much for them. Nick is particular is a very honest person, doesnt over charge and is so good at what he does, that we feel really comfortable woth all his suggestions as they all are for our benefit. The funny thing is some of the decisions he makes were cheaper for us but never scampperred on quality. Finally Nick is a good man, very hard working and if you want a builder who is talented, experienced and honest- your search is over! Get these guys in! You wont be disappointed! A genuine and honest review from a very happy customer! Thanks Nick and NCM for our dream home! - R B

Nick and his team built my loft extension. The quality of work was to a very high standard and I’m delighted with the result. Nick was able to resolve any issues that cropped up, he is very approachable, friendly and courteous. He was able to advise me before I took decisions on things like tiles or fixtures and fittings. Nick and his team worked very fast and they were conscious of the impact of the work on the neighbours. I would have no hesitation in recommending the company. - r & v

We are very pleased that we have chosen NCM Building . We were listened to and all decision were taken together with Nick who explained to us all the steps and stages from the start to finish. All the workmen worked hard, are respectful and professional. All the aspect of the refurbishment and loft conversion were taken care of and develop to perfection. Nick and his team were always very helpful. We have no building experience and someone like Nick who is honest , reliable and takes the time to listen to us was a great help We will definitely use again. - A O
