Extensions- 19 Jun 2016
Neno is a very warm-hearted and genuine person. He gives his 100% to the job. He is also very prompt when it comes to communication and is always available by phone/text/email. He has a vast experience and good technical know-how and produced excellent plans and drawings. His quotes were very reasonable and offer excellent value for your hard earned money. Having been his client, I am genuinely inclined to believe he is a person who would never "rip off" his clients. He is a man of his word and does what he says. However, Neno's honesty and confidence can be a bit blunt at times. He can be quite “direct” with his opinions and this may rub off some people the wrong way, e.g. your local Council Planning officer may be an a**hole, but if you "confront" him, he will definitely not make things any easier for you- nevertheless, Neno dealt with all the Council red tape and followed up the Planning Permission Application to its conclusion. We finally got permission for extending the property much less than what we had expected initially- apparently our local Council (Hillingdon) has its own set of Draconian conservative rules that we were unaware of- but we have postponed the actual project work due to a recent change in personal circumstances. Summary: Based on my personal experience, I would DEFINITELY RECOMMEND Neno as a bona fide Tradesman on MyBuilder.com.

Painting & Decorating- 12 Feb 2019
He truly showed professionalism that I had struggled as a guest house operator to get from handy people. He would go out of his way to satisfy. The finished redecorated room project was a masterpiece and took a little longer than planned because of the weather but he gave it his all! I am pleased I took a chance on him as there was no review on his profile when I hired him. I would however, pay attention to work and point out issues as they come up otherwise, you will have dirt and rubbish to content with as the workers leave all the mess after work.

Restoration & Refurbishment- 5 Apr 2025
Where do I begin? So Alex and his team has pretty much renovated two flats including external work such as roofing. The work involved was quite challenging as the building has a lot of damp / mould / leaking issues. Alex’s attitude towards resolving every matter was exemplary. He would take his time to explain his strategy to tackle each and every problem in a very metholodical way. I have never seen anything like it. I am so pleased with Alex’s work and so are my tenants who live in the flats. I would highly recommend Alex, especially for tougher jobs!

We recently completed a first and second floor renovation alongside an 5x6m extension of our 1930s property with Maxcontractorsint.ltd , and we couldn’t be happier with the results. From start to finish, they have been absolutely fantastic. The attention to detail and the quality of workmanship throughout the project has been exceptional. Matt and his team are incredible, they worked efficiently, kept work on track, and made sure we were updated and involved at every stage. Their skills, ideas, and collaborative approach truly brought the whole project together. Communication throughout the project was good, and the team provided great pre and post project support. Matt was very detail-oriented, offered inspiration during site visits, and was supportive of our requests along the way. We’re so happy with the end result and would absolutely recommend Maxcontractorsint.ltd for any project.

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.

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

Your Merton 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 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.
