Mohsen went above and beyond with our kitchen face lift. He did exactly as asked, to a very professional standard. Mohsen is very hard working, has high standards and was reliable. He also suggested ways to improve our kitchen, and corrected some previous poor work from other builders! We love the job and will definitely use Mohsen and his team again for future work.

RMD Replaced three bathrooms, cloak, en-suite and family. The work was planned so that disruption was kept to a minimum and we were give practical advice throughout as we made the detailed decisions during fitting. The work, including cabinet making, was excellent and carried out with an eye for detail. Alex has a 'belt and braces' approach so everything was fitted to last even if it required additional work and preparation. It was all done to budget too and the pricing was fair, open and honest. RMD proved to be great quality, trustworthy, a pleasure to work with and we wouldn't hesitate to recommend them.
