Liam was extremely professional, job completed to a five star finish. It was for my elderly mum and dad and he was very conscientious & patient towards them whilst doing the building works. They left NO mess and even went the extra mile on a couple of minor asks during the job. Cant recommend highly enough.

We were absolutely delighted with Lino and his services. He was incredibly patient , as our flat purchase was delayed. We required a total gutting off our flat, with new kitchen and bathroom, new flooring, painting, and all the rest. He had great communication throughout. He showed up on time with his team each day , and was so professional throughout. We went to Lino for advice throughout the process. He never said any of our plans were not possible- he always either said yes, or provided another option. This was such a great help. I would recommend Lino to anyone. We are absolutely delighted with our flat.

Edmond did stellar work on the full kitchen renovation of our central London flat, and I can't recommend him highly enough. His professionalism, expertise, and attention to detail are on another level, and he is an excellent communicator. The end result was meticulous; he worked efficiently within the agreed timelines while resolving unexpected challenges and providing solid guidance throughout the project. Edmond also has a strong network of professionals who were just as reliable and easy to work with as he is. We also appreciated how tidy our home was left every day and how well all areas were protected during the build.

We've been seriously impressed with Pawel and his team. They opened up our rear dining room/kitchen wall using an RSJ, following our engineer's drawings perfectly. They also did a few bits of plumbing and bricked up one of the windows at the rear, which is where the new kitchen will be fitted. They were incredibly tidy and really pleasant and courteous to be around, which my wife was so grateful for given we live in a busy family house (most builders are not like this...), I can't thank them enough! We will definitely be using them again in the not-so-distant future!

Restoration & Refurbishment- 16 Feb 2018
Adam and his team did a brilliant job! My flat was in very bad condition. They gutted the whole flat and refurbished everything to a very high standard. Work performed included, new boiler and radiators installation, complete refit of bathroom and kitchen including all tiling, plumbing and electrics, new spotlights and wooden flooring throughout, new doors and skirting boards and all painting and decorating. They also arranged for all skips and rubbish clearance. I simply left the keys with Adam and he performed all work with minimum guidance. I would touch base a couple of times every week or when things needed to be discussed. He was happy to purchase most materials and provide receipts. I would highly recommend Adam and will definitely use him again for future work.

An extension builder in Merton 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.

What experience do you have with similar extensions in Merton?

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 Merton extension builder’s ability to deliver a result that meets your expectations.
