Kitchen Fitting- 12 Jul 2026
Ali was brilliant at fitting my tap - it was more complicated than we thought and he stayed longer to make sure it was done, and even came back the next day to fix something that had gone wrong. Mohammad was brilliant, helping me with every enquiry and always answering really quickly, and patiently - super helpful. Overall, excellent - really happy - would definitely hire again.

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.

What to ask a Lewisham extension builder before hiring?

Before hiring an extension builder in Lewisham or extension building company in Lewisham, 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 Lewisham?

An extension builder in Lewisham 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 Lewisham 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 Lewisham?

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 Lewisham 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 Lewisham 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.
