Extension Builder in Belmont
We are an all-in-one renovation and kitchen company based in London, with over 22 years of hands-on experience in building, refurbishment, and kitchen installation. What makes us different is simple, we handle everything from start to finish. From the initial design and product selection through to full installation and finishing. No subcontractors, no passing you between different tradespeople. One team, one point of contact, one standard of work throughout. We have our own kitchen showroom in Sutton where customers are welcome to come and see kitchens, worktops, and finishes in person before making any decisions. This means you get proper design advice, not just someone turning up to fit whatever you've ordered online. Over 22 years we have completed hundreds of projects across London, full home refurbishments, kitchen renovations, bathroom installations, extensions, and general building work. We understand both the construction side and the design side, which means the job is done right and it looks right. We are straightforward to deal with, honest pricing, clear communication, and we see every job through to completion. Our reputation over 22 years has been built entirely on the quality of our work.

Kitchen Fitting- 24 Oct 2016
Kris, Gustav and their team have been absolutely amazing, cannot praise them enough. First of all - the job ended up being a lot larger than initially thought- as decided to replace old ceilings and flooring, walls -everything was uneven to start with. So took everything back to 'bare bones' and pretty much built it up again as a new house. New electrics, water pipes, completely new kitchen and bathroom. I really appreciate they were very straightforward with the estimated costs from the beginning - it did run slightly over budget but nothing too bad as had some contingency funds prepared. I would have hated to be quoted one price then half way through the project to discover it escalates out of control. Thankfully they are really honest and reliable. They were always easy to reach and replied any question I might have had in a timely manner. This was particularly important to me as I was between uk and us at the time so couln't be 'looking over their shoulder' so to speak. Last but not least the finish and quality of works is absolutely amazing! They couldn't have paid more attention to every little detail if it was their own home. For instance I remember last day of work when they were tidying up Gustav came back to put up door stoppers for me, completely on his own initiative. It's just a little touch but goes to show the dedication they've put into the project and care about the finished product.

Groundwork & Foundations- 26 Feb 2025
I hired John to build a concrete base for a garden building installation and he did a great job, resulting in follow-on work for him laying a new Indian sandstone patio in front of the building, which he also did to a high standard. After receiving several quotes from different firms, I selected John because he asked the right questions, clearly thought about the solution and was interested in ensuring the result was the right one right for me. He's a lovely bloke and a pleasure to have working here. He works on his own and for the most part keeps himself to himself, wasn't fussed about tweaking the scope here or there as the plan developed and kept the place pretty tidy throughout. I will be using him again for sure, so I wholeheartedly recommend John for any work you're considering hiring him for.

Extensions- 5 Mar 2025
[ VERY DISAPPOINTED] I hired those guys to do what was left on my Extainsion and at the stars I realised that they are not professionals as soon as they started to do the isolation on the roof. That is one, Number two partition wall, wrong, and when I realised I told them and they admitted they knew it but they thought it will go undetected Since then they didn't answer my calls or responded to my messages. And then they decided to go and leave the job unfinished. This was because I already paid them more then they had done work for. The last bit of work was the screed even that is not done properly as they left 3CM under the needed level and now I have to add an other layer of screed before the self levelling. Unprofessional and very untrusded.

I am so happy with the work and professionalism of Tom and James. I had queried several companies and decided to work with G2 brothers based on how open and honest they were on the first visit for estimation of work. We discussed the work I wanted done, which was to replace the cabinets in the kitchen. We also discussed the budget I had and what the overall look I was going for. Throughout the whole project we discussed options, impacts and agreed together on next steps. They were a pleasure to work with, I will definitely use their services again. Great work!!!

Painting & Decorating- 3 Sep 2024
Great, reliable contractors. Had a full flat repaint job with some minor repairs (blinds fixing, handle replacement). Claudia was very efficient and responsive in communication. All was arranged pretty quick, appointment attended on time and kept to time schedule agreed. Had done a great job with repaint and provided reasonable rates. Also helped out with few minor repairs so I didn't have to get someone else. Very happy with the service , will certainly hire again. Thank you guys.
