Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!
Dmitry
Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

I initially left a 5-star review because the job seemed well done. Unfortunately, that wasn't the case. The replacement lock stopped working within two days and had to be repaired again. The inner safety glass panel also shattered two days after the work. I can't say what caused the glass to break, as nobody touched it after he left, but the timing is very concerning. I started with a faulty lock and ended up with a shattered glass panel.

NMB have renewed my faith in builders! Nevin came to quote my job and we spent a good 2 hours planning every aspect of the project.

Their attention to detail is second to none! I have recommended NMB to my friends and I look forward to using them again In the future.

Experienced builder NEW TO RATED PEOPLE ???? Hi everyone. I’m Mitch, I’ve been in the trade since leaving school. I am a general builder that specialises in timber work. I do most jobs from small jobs like laminate flooring all the way upto 2 storey extensions. For the larger jobs I have a reliable team of builders including electricians, plumbers and bricklayers. We are happy to quote anything, bespoke is my passion. If you can’t get someone to build it, we can! Please feel free to browse photos of my work, I will try upload a little bit of everything. If you don’t see a photo of a job your asking for, feel free to contact me and I’m sure I will be able to show you examples of my work in that area. Friendly team of lads aging between 18 and 66! We look forward to working with you. P.s as mention above we are new to rated trades and as such have decades of experience, thousands of builds under our belts but alas, no rating on here. Any and all feedback will be most welcome. Stay safe everyone and see you on the job!
