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.

Latest review:
We recently had Mng Roofing Ltd carry out a new flat roof installation on our property, and we couldn't be happier with the results. From the first inspection to completion, the team were professional, reliable, and kept us updated throughout the process. The workmanship was excellent, and the site was left clean and tidy, and everything was completed on time. We now have peace of mind knowing our roof is watertight and backed by a guarantee. Highly recommend Mng Roofing Ltd to anyone needing quality roofing work done.
