Mike transformed our dark and dingy garage into a fabulous annexe to our home. The job was not easy but nothing seemed to faze him. He was more than willing to go the extra mile and was happy as long as we were too. Highly recommended and a really nice chap.

The guys worked incredibly hard and the workmanship was exceptional. They gave a good quote and got the work finished quickly and without leaving a mess. They were very friendly and respected the fact I couldn't let the cats outside. I would highly recommend.

Rob and his team did a really high quality job and we are very pleased with the end result (and I am the son of a builder, so my expectations were high to start with).. The finish is excellent on the render and the quality is constant through what was a fairly large rendering job on my detached house. The team were tidy and worked hard to the deadline throughout the process. If you need a high quality rendering job, then I would highly recommending considering Rob's services.
