Latest review:
When Mr Nesimi came to undertake a pre-assessment for my front wall, he came across very professional and genuine and very honest about the work needed doing. He even suggested some changes to the work to reduce cost. The quote he gave me for the job was very reasonable and he was able to slot in my job within a week and arrive sharp on time at 8am and got on to the job straight away as I had a busy day at work for me to attend to. I notice that right from the start he was very clean and meticulous with the work and his job was of a very high quality ( compared to a job I had done by another builder 9 months ago). My neighbours also noticed this difference and were praising Mr Nesimi’s work. I would definitely recommend Mr Nesimi for any construction work as I felt he was very professional, reliable and honest and most of all the work was of high quality. I will be certainly calling him for my next job, most likely the driveway resurfacing and the attic conversion within the next year.

Extensions- 4 Jun 2021
We needed a kitchen extension, and after getting 10 quotes from local builders, M & G were extremely competitive on price. The whole process was made simple, mainly due to the knowledge and communication from Miri and his team. Before I chose M & G, I was invited to see other jobs they were working on and after seeing the first extension, my mind was made up. Miri and his team are Punctual, Tidy, Knowledgeable, Professional, Hardworking and I cant recommend them high enough. I will be hiring Miri and the team for our Loft conversion soon.
