Latest review:
Hi, Dan recently completed a loft conversion and ground floor extension for our house in Ealing. It is the second time I've used him for a loft conversion. We are delighted with the work, team, price and timing and I highly recommend him. Dan is entirely trustworthy, and the team are a mixture of his family, friends and choir group. Like all projects there were a few snags and without fail Dan was pragmatic, helpful and keen to make sure we were happy with the quality at the end. I've recommended him to neighbours on both sides who are both pleased and happy to recommend him.

Latest review:
Florin extended and completely refurbished our 4-bedroom semi-detached house. This included extensive steelwork, underfloor heating, complete re-plumbing and rewiring, excavation, and an entirely new slate roof as well as varying extensions up to three floors high. I cannot say enough good things about his workmanship, professionalism and reliability. His workmanship makes a perfectionist like myself happy. He is also completely professional: even with our difficult neighbours he was always courteous and understanding, and even helped them sort out issues at a moment’s notice that had nothing to do with his building work on our property. And he is also thoroughly reliable. I cannot think of any instance where he committed to something and did not deliver — he even managed to finish all the work on our house ahead of schedule and on budget. We have been so happy with his work that we contracted him to build us a summer house as well, from scratch, and to complete revamping our front garden including elements of hard landscaping. Again he delivered flawlessly and we are very happy with the result. We also continually receive positive comments from people passing by and just seeing the front garden. We have used several other builders in the past on other properties, including far more expensive ones, and none compare to his level of competence, attention to detail in his workmanship, his complete professionalism and thorough reliability. Now that we have found Florin, we will never look for another builder again. I just hope once others experience what he delivers for themselves he will still have some availability for us in the future!

Extensions- 4 Jun 2021
We needed a kitchen extension, and after getting 10 quotes from local builders, M & G were extremely competitive on price. The whole process was made simple, mainly due to the knowledge and communication from Miri and his team. Before I chose M & G, I was invited to see other jobs they were working on and after seeing the first extension, my mind was made up. Miri and his team are Punctual, Tidy, Knowledgeable, Professional, Hardworking and I cant recommend them high enough. I will be hiring Miri and the team for our Loft conversion soon.

What to ask a Haringey extension builder before hiring?

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

An extension builder in Haringey 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?

What experience do you have with similar extensions in Haringey?

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 Haringey 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 Haringey 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.
