Our build prerequisites were to divide a room & close an open archway, build two extra walls, move steps and a handrail, put in two entrances with doors for the new build and paint & carpet this area. Matthew (MDCC Construction) was qualified and very helpful – giving us good advice. He is an honest, tidy and thorough builder, willing to accommodate the building manager's questions and happy to make amendments. We were thrilled with the speed and finish of this build, and we will definitely use them again.

We asked Valon to lay porcelain slabs along the border of our garden. He responded to our request quickly and popped around beforehand to view the garden. His quote was less than anyone else’s and despite allowing one day to complete the work, it took 1.5 days and he didn’t charge us any more. His workmanship was of a high quality and we would highly recommend him. He also undertakes building work as well as gardens so he will definitely be out go to person in future

I cannot speak highly enough of the MBS team. They were everything one would expect from a service provider. They were punctual, polite, they knew what they were doing, the quality of workmanship was high, they were honest and their prices are fair. Most of all -they were reliable and clearly had our best interests at heart. I wouldn't hesitate to recommend them to any other prospective customers. Excellent!
