Lerida was excellent- would highly recommend. Met with us, understood our needs, and produced a good set of options and designs. Our preferred option was then tweaked further with great attention to detail shown. We are now looking forward to working with them on the build of the project.

Bagnall Brickwork provided great service when I requested a quote to reinforce a wall for a heavy 50kg TV mount. Although they didn’t end up doing the work, their honest advice helped me realise that reinforcement wasn’t actually necessary for my situation. Thanks to their guidance, I was able to find a much more cost-effective and appropriate solution without compromising safety or quality. This experience shows their ethical approach - they prioritise giving trustworthy advice over making unnecessary sales. Highly recommended for anyone seeking professional, reliable, and principled brickwork or building services.

We completely renovated our home, which included building a new side and back extension. Mr. Manaj did a fantastic job installing new plumbing, decorating, new flooring with heating, suspended ceilings, a new kitchen, and partition walls. We are overjoyed with how beautiful the house has turned out. Mr. Manaj was really competent and dependable; the work was completed on schedule, and I would highly recommend him as a worker.

Extensions- 6 Jan 2020
Aaron and his team were fantastic! They worked tirelessly to get the build completed on schedule and were tidy and considerate in doing so. They consulted and updated me all the way through the build and were accommodating with a few last minute changes on my end. They also refurbed a few rooms while doing the main extension and were hugely accommodating in managing that in such that we could move our daughter from one room to the other minimising the disruption our end. I couldn't recommend them enough. Good, honest, integrity and hard working. A rarity in the trade now days!

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.

Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

Dunster House Garden Office (5m x 2.5m build) We are absolutely delighted with the garden office that Michal and Lenka built for us. From start to finish, their expertise and attention to detail shone through. They guided us with thoughtful consultation, listened carefully to our ideas, and delivered a finished office that is both beautiful and practical. Their work ethic, professionalism, and friendly approach made the whole process stress-free and enjoyable. The quality of the build is outstanding, and it’s clear they take great pride in what they do. This was a 10/10 experience, and we could not recommend them highly enough! We also used them again for another job to build install a Pantry; Michal and Lenka recently built and fitted a bespoke pantry for us using Howdens units, and we are beyond impressed. Their knowledge and craftsmanship are second to none. They made excellent recommendations throughout the process, ensuring the final result was exactly what we needed.
