The Job was to extend the rear of the house on the ground floor, open up the kitchen and reception room into one open plan living area, to refresh the rest of the house which included new plaster skim, doors and frames and to fit new bathrooms and kitchen as well as an rewire on the whole house and the construction of a retaining wall in the garden to accommodate the extension. Florins team were excellent from start to finish, the whole project was completed in record time to a very high standard. The 10 weeks turnaround was incredible, we were very happy that Florin was always here at the property or on the end of the phone throughout the process, his professional advice and smart ideas made for a smooth transition from room to room. The team were very hard working, polite and knowledgeable, these guys worked very hard and very quickly which was amazing to see and I was very grateful we were able to move into the property earlier than planned which even saved us money on the temporary accommodation we had! Can’t thank you enough Florin, any small issues we had were dealt with quickly and smoothly, I love the house, the level of work and would 100% use Florin and his team on my next project!

Groundwork & Foundations- 7 Nov 2024
From start to finish, Bogdan and his team were exceptional. After dealing with a previous builder who caused numerous delays, I found SBG Services. Bogdan came by the same day to assess the job and impressed me with his extensive knowledge. Given my tight schedule, he got to work immediately. I’ve never seen a builder work as hard as his team; they labored tirelessly from morning to night to ensure the project was completed promptly without compromising quality. Every trade I've had since has commented on their attention to detail. In just three weeks, they completed two extensions and transformed my garden. I will definitely be calling Bogdan back to handle my front garden early next spring.

Extensions- 4 Aug 2020
On a cold November evening, Tony and his team turned up to provide a quote and within a week this was received. The quoted price came in the middle of the pile, which was a good start and aligned closely to the ballpark figure I'd received from a friend who was also in the trade. We then visited a site they were finishing off, and Tony had the confidence to ask us to speak to the client without him there and they gave us the confidence to proceed. They started in January 2020 and rapidly moved through the works and engaged closely with my architect, Structural engineer and building control and proceeded based on their recommendations strictly. We lived in the property as build progressed and the team ensured that the site was secure every evening and we were safe. As COVID-19 hit and we went into Lockdown, the team continued to come and work (we were separated from them as the house was boarded up) and the only challenge was getting supplies. Tony scoured all over London, picking up items as best as he could and work continued. Once they'd broken through into the old part of the house they continued to progress rapidly and showed utter professionalism. The team lead's attention to detail is impressive, and he gave great recommendations on what would be the right approach when we were laying out features such as window sizing and lighting. The standard of work is excellent and I would highly recommend them.
