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!!!

I've used Facundo's team to install a new shower, including wall and floor tiling, massage jets, and concealed shower equipment. Facundo was the person we dealt with at all times, although someone else was assigned to do the job. The quality of the work and finish is extremely good. I was also impressed with Facundo's professional attitude at all times, being very polite and respectful, as well as proactive in addressing any potential issues affecting our planning and execution. Highly recommended.

Kitchen Fitting- 11 Oct 2018
Mohsen went above and beyond with our kitchen face lift. He did exactly as asked, to a very professional standard. Mohsen is very hard working, has high standards and was reliable. He also suggested ways to improve our kitchen, and corrected some previous poor work from other builders! We love the job and will definitely use Mohsen and his team again for future work.

Extensions- 24 May 2024
We asked BLG to complete a different job to the one we advertised as weren't ready to start it. Instead they completed a 2 bedroom flat renovation, including ripping out and installation of kitchen, removing plasterboard walls, making good, painting and decorating and recarpeting/tiling. Their work and professionalism was great but even better was their attitude. They were always quick to find good solutions to problems, were extremely accomodating, informative, hard working and prices were very reasonable - at no point did I feel I was being ripped off or being treated like a mug, which after completing multiple renovations in the past am well aware of. I wouldn't hesitate to recommend them.

Restoration & Refurbishment- 21 Jul 2025
Despite the fact that CRI was a new member on the app with very few reviews, Jon came across very professional and accommodating and priced the job swiftly and fairly. I took a pun and awarded CRI the job. It took circa 2weeks and during this time Jon and the team where exceptional. In order to catch up and meet deadlines they were more than happy to do full weekends and always left the site clean and tidy. During the works, the team always kept me in the loop with photo updates on whatapp and next steps. I would highly recommend CRI.

Extensions- 31 Aug 2024
BS Loft Conversions are reliable, honest and operate with integrity. I recommend them to anyone who is looking for some building work whether they are big or small projects. They arrive on time, work hard and leave the site clean and tidy. Anxehlo always takes the time to answer any questions we may have and talks us through the process before providing us with all the options available from repair, replacement or re-instatement. As a novice to a huge development, it was difficult to find builders you can trust but, Anxhelo made that process easier, restoring our faith in construction work.
