Bathroom Fitting- 21 Jun 2022
We are not entirely satisfied with Ludovic's work. Some of the tiles were not cut to the correct messurement which left big gaps in between. Worse still, the grouting was very messy and did not have a smooth finish. We will now have to get another Tiler to redo some of the tiling work. Overall, it was not a professional job and we are not very happy with his workmanship.

Very few tradesmen can engage in a detailed, professional and friendly manner. They took out an old kitchen and replaced it with a new one - which the helped source at below market cost saving us in excess of £5000. Right from conception to finish, there was full transparency of the costs and crucially at the end, no cost overruns. Definitely five stars and will reengage again for other building/renovation works I have planned.

Bathroom Fitting- 30 May 2022
Mohammed Huda and his builder were professional and quick to attend our job –– recommend! The communication was fast and professional. Mohammed provided a detailed quote (our job had to go through insurance) that is fair and transparent. The builder who came around, Jafa, was very respectful to our things. We were able to trust him from the get-go and had a peace of mind when he was working. He works incredibly hard and is methodical in his process (e.g. painting ceiling first, then walls, so to avoid splatter unevenness). They responded to our requests quickly and fixed things we weren't 100% happy with. The team finished the job ahead of time, and gave us tips for refurbishing in the future. Very happy and highly recommend!
