Restoration & Refurbishment- 28 Apr 2024
I highly recommend these people if you want to be fleeced, taken advantage of, treated appallingly and work left unfinished. The standard of work is below average. If you want high quality finishing do not come here. I’ve had to spend a lot to redo a lot of their mistakes and mess. If Jerzy could charge you for every single nail he would, so beware. And when you challenge, they get aggressive and nasty. Very unprofessional. Do yourself a favour and keep away. So thanks Jerzy and co for a load of stress and rubbish. I am happy to talk to anyone and advise against these people.

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.

Completing our scope with Insight ProBuild from start to finish was one of the most least stressful projects we have ever completed. From start to finish, Anil was on hand generating creative ideas/suggestions, providing clear and achievable plans/schedules, and managing the scope to our agreed budget. Overall, Anil earned our trust through careful management of the Project, handling all the interfaces and taking the stress away from us, having a clear eye for detail and quality of his product, excellent communication through regular engagement with us and ultimately delivering a high-quality Project in the end. Even after completion, Anil was excellent by following up on any issues and ensuring we were still happy with the completed scope. Would recommend Insight ProBuild as Anil genuinely cares about his product and prioritising the relationship with his clients to ensure they are satisfied and happy.

Extensions- 30 Jan 2023
I had the pleasure of having them carry out a single story extension and fibreglass new roof of my property. I found they always turned up when specified and carried out fantastic quality work for a competitive price. Not being a builder you have to place trust in a person / company. They always made sure that we were happy keeping us updated with the project every step of the way. They were kind and considerate to our neighbours making sure they were not loud early in the morning or late in the evenings making the whole process run smoothly. I can not stress enough how great these guys are. Thanks
