Matt undertook a 4 month project which involved removing walls, installing flooring, kitchen, bathrooms, new radiators, windows, bifold doors. He was 100% reliable and was onsite daily, always happy to give guidance and advice and worked tirelessly to ensure our building went to plan. His work is of a high standard and he has a positive outlook making it easy to work with him and resolve issues. We are over the moon with the end result and would not hesitate to recommend Matt or use him again.

They turned up without any materials and we had difficulty getting any. The fence has been put up in a bad way with short posts, and screws dangerously protruding through to next door. My old patio was not taken up as quoted, and new slabs were laid over the top. It is not level and slopes forward & sideways with a bump in the middle. Slabs are uneven, the built step has all broken away, as there is little support under it. And the grouting has gaps and different grouts used. Too many other probs to list.

Hired paul to reconfigure my kitchen. He did not complete the job and walked out after 3 weeks leaving numerous jobs unfinished. Many things they did have had to be redone, the finish was shoddy and I don't think he knows what a right angle is. Would obviously not recommend, other tradesmen that have seen his workmanship have told me to report him to trading standards. He left me with a half finished job, saying he was not able to achieve the level of finish I was looking for.
