Extensions- 15 Jul 2019
Norbert and his team have transformed our house to the most amazing standard, we would recommend them to all our friends and family. The work schedule was managed so well, with minimal disruption to us with two young boys. We had a loft conversion, main bathroom renovation, utility room, downstairs toilet and a 4 meter kitchen extension. We stayed in the house whilst the work was being completed and Norbert and his team fitted in so well, it actually feels weird not seeing them in the house. They are such a lovely bunch of people. We are over the moon… on time, on budget and finished to a high standard. If we ever undertake renovation work again, Norbert and his team would be our 1st call!

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- 27 Jun 2022
Very very happy with Michael's work. From the day one of the meet till end of the project, he and his team been quite professional and have been working with high standards. We received range of quotes from different builders and Michael's quote was somewhere in middle with good quality of work which we have seen during our site visit for his other projects. So, decided to go with him. One really good thing you get from Michael is plenty of ideas and options. From our original drawings, he suggested some changes which were really useful. Being a lay people, During the project we were confused in some design options and Michael really assisted with 3 to 4 options and he suggests which one is the best from his view point but also been flexible if we wanted to do in specific way. He was daily coming to the site to monitor quality and progress of the work. All his team is highly skilled and experienced. The all do general building but when it comes to specific, they have specific tiles, electrician, plumber, painter etc etc who finishes the job at very high quality. They work flexible to complete the job on time and keep the area safe and tidy. In terms of managing project in budget, we had a good experience where Michael will in detail explain what is covered in agreed amount and where the extra cost will incur if there are major changes. I am taking this much time to write this review so that it can help others to see my good experience with Michael. 100% best.

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.

Tom Reilly recently fitted a kitchen for me and I am very pleased with the result. The work he has done cannot be faulted. Tom was reliable and came when he said he would.

I am delighted with my new cast iron Victorian air bricks with grills! Jacek took the old ones out and inserted the new ones. The job is extremely neat and the area left completely immaculately. A few neighbours have taken his number for more work. You will find Jacek extremely polite and amiable, professional, hard working and very knowledgeable about his particular trade. His price was competitive and I would have no hesitation in recommending him. I will be hiring again for other structural work. A great professional find!!

What to ask a Surrey extension builder before hiring?

Before hiring an extension builder in Surrey or extension building company in Surrey, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Surrey?

An extension builder in Surrey should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Surrey extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Surrey?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Surrey extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Surrey extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
