Kitchen Fitting- 12 Nov 2022
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!!!

Fully electrify a new rear, 2 storey side, porch extension and shed. Arek was always the first one on site, worked very professionally, interacted well with the other builders and was happy to accommodate minor changes to the project.

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!

I recently hired Vithesh for a loft conversion, and I couldn't be happier with the results! He completed the project with exceptional quality and efficiency. The structural floor beams and steel structure were flawlessly installed, and the roof comes with a reassuring 10-year warranty. What impressed me the most was his ability to complete the structural job in just 3 weeks, even though the original estimate was 5 weeks. His commitment to meeting deadlines and delivering high-quality work is truly commendable. I’m absolutely thrilled with the outcome and will definitely be calling him for any future projects in my home. Thank you, Vithesh, for a job well done!
