Extensions- 22 Oct 2018
Choosing MM builders was the best decision we could have made. Initial meetings: They took time to ensure they understand our work. They never complicated matters nor tried to hide things in any fine print and provided us with a estimated schedule and explained we would be kept up to date at all stages. Works: Their knowledge and work ethic is amazing and is reflected in their work. They gave us confidence and built trust very quickly. Always willing to go the extra mile and used their expertise to help us rectify issues or make suggestions in areas we would have never noticed ot thought of. Sam, Ross, Bill & Harry were so pleasant to have around the house. They were very conscious of the 3 young children in the house of which one has additional needs. They minimised disruption which is very difficult when doing major work in a areas and were always friendly and polite. We had no issues in having them inside our property which is very important when completing works taking just over 5 months. They work with specialist tradesman (tiler, plasterer, etc.) who are equally good at their trades. MM were very professional when it came to liasing with Building Control and made sure they were involved and visited at all key points. The aftercare we received was as good as we had received throughout the process. I have no hesitation in recommending MM for any building works. If I was to ever undertake any works in the future, it would be by them and only them.

Extensions- 25 Apr 2018
Initially when using My Builder, I didn’t really have any intentions of working with tradesmen from here, it was more to benchmark and see where a quotation would be priced however upon meeting Vijay, that pretty much changed from the first meeting. If you’re looking for someone who treats your project like their own, he’s the man. Vijay takes 110% pride and care into every aspect of your project. Although work is yet to commence on my property, the spec Vijay has put together itself is worth a lot of money, and most would consider it invaluable. From my opinion so far, no stone will be left unturned where Vijay’s project management and work is concerned. Without thinking twice, I would highly recommend anyone considering Vijay, to at the very least, meet with him and show him the work required. From there on, your mind will be made up. Looking forward to working with him in due course

Extensions- 30 Dec 2021
Its been a pleasure having Albi and his team build our extenstion. Excellent job done (we had a 32 sq m extension for a new kitchen/dining room and the build was seamless). Good workmanship and genuinely easy to interact with. Albi kept to the timelines, offered good suggestions and delivered excellently. Albi and his team are reliable and provided a competitive fair price. They would be here early (7.30 - 5) 6 days a week and were a genuine pleasure to deal with. They were neat (even covering our drive with mdf panels to protect it from rubble) and then pressure washing it clean at the end. Works included Foundations Construction work Skylights Roof structure and roofing Windows/Bi fold door Exterior render Insulation Woodwork - doors, architraves, skirting Plumbing Electrics Plastering Paint Flooring (wood & tile) Tiling Installing kitchen
