Simply the BEST! I would give them 10 stars if I could. Outstanding work, outstanding service, outstanding quality, outstanding level of detail and outstanding people. Shadi, Rabee and team, not only sorted out my leak, they undertook a major project to repipe my home, fix electrics, paint , put up new storage space, carpentry work , fixing walls etc. The first time that I have seen any builder finish weeks ahead of schedule. They are extremely well organised and operate to the highest degree of precision.

Paul repointed a garden wall that was starting to crumble. Excellent work. He was on time, super friendly, and easy to talk to and he did a great job. I was also very happy with the price which was below what others had quoted.

The work was managed efficiently, and great care was taken throughout the project. I’m very pleased with the results and would highly recommend Luke and his team for their professionalism and attention to detail.

Fantastic work. Andy is very professional and knowledgeable. Prompt, friendly and very competitive prices. We are building a 2 storey side extension and Andy is doing all the building works. We have a very difficult set of footings which involves a line of trees close by. Foundations passed by Building Control with flying colours. Very satisfied and Andy will be quoting for other work I have planned and I am sure we will be working together for sometime now. Would recommend him to anyone.
