Ivan and his team completed a full loft conversion at our terraced house, and we couldn’t recommend them more highly. They did a fantastic job from start to finish and were a pleasure to work with. Communication and project management throughout the project was excellent, and their commitment really showed. Nothing was ever too much trouble to ask. The project was completed within the estimated timeframe, which was especially appreciated as it finished just before Christmas. The team was very considerate while working in our home, and we stayed in the house for the entire duration of the project with minimal disruption. In addition to the loft conversion, they also replaced all our doors with fire doors and installed new flooring throughout the house, all to a very high standard. We’re absolutely delighted with the results and would highly recommend Ivan and his team to anyone considering similar work.

I charge 60£ for a home visit and quote. This is to cover for my time and the website fee attributed to each add. If the jobs goes trough, this cost will be included in the final price. Hi, I am Flo, your local handyman with a decade plus of experience. Putting up a frame or building up an house extension, I can accommodate both and everything in between. If you have a project in mind i have a decade plus of experience that could come in handy so let’s get in touch. Yours sincerely, Florentin.

Bathroom Fitting- 22 Sep 2025
I recently had my bathroom completely renovated by Zsolt and Mario and the experience was outstanding from start to finish. They were professional, punctual, and incredibly skilled—nothing was too much trouble, and their attention to detail was second to none. One of the highlights of the project was the walk-in shower they installed, It’s beautifully tiled, and gives the bathroom a sleek, modern feel. They kept the workspace clean, communicated clearly throughout. Zsolt clearly take pride in their work, and it shows in the final result. The bathroom looks fantastic and feels like a real upgrade to the home. I wouldn’t hesitate to recommend them to anyone looking for trustworthy, high-quality builders. Thanks again, Zsolt and the rest of the team, you’ve done a brilliant job.

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.

Windows & Doors (uPVC & Metal)- 13 Jun 2024
Job done promptly and within the budget required. The window was put in place so quickly I didn’t have a chance to wipe the dust of it before it went in! Would suggest the fitter carries a cloth with him to wipe fingerprints and bits off the window before installation but really a small thing considering. Overall very happy with the job done. Thanks.

Carpentry- 31 May 2017
Was really impressed with these guys. Helped me order the correct garden door and then went to pick up extra bits when the order didn't turn up correctly, for no extra cost and couldn't have been nicer about it, even though it was a pain for them. Really cheerful and helpful - nothing was too much trouble. Would use them again, for sure.

Kamil and his colleague were brilliant and I’d highly recommend them. We had a ceiling crack that was bowing, Kamil correctly identified the issue and fixed it. He also sanded and primed our ceiling and walls, ready for us to paint. Kamil & his colleague worked really hard to finish the job in just two days and were polite and tidy. He was clear and considerate about the costs.

Richard and his team have always been very hard working, respectful and professional throughout the project. We have had an extension, utility and bathroom/toilet renovation and we are very happy with the quality of work. It has transformed our home into a beautiful living space. Richard was very helpful when giving advice on materials we were choosing. The team were very accommodating to our needs, easy to work with and always tidied up after themselves.

My house was old and its condition was poor. Much were needed to be fix. The original kitchen layout were also inconvenience to my wife. I need to have all these changed under limited time. This builders have a team of specialists on almost every aspect. They gave me variety on the layout design and choose of materials. This saved me money, time and tons of trouble to find difference contractors. The after service and their respond time are very good too. I hope by sharing my happy experience can save your money and trouble to find a good contractor.
