    Shell for 3x6m extension

    Posted 02 December 2025

    Working with Sebastian and Jonny was an absolute pleasure from start to finish. From day one, it was clear they and their team take genuine pride in their work and it shows in what they do. The entire team was incredibly courteous and professional, and as we have a mid terraced house they did their best keeping the hallway clean and dust free throughout the project. The quality of their work speaks for itself, and their attention to detail made the whole experience stress-free. I would highly recommend them without hesitation and would absolutely work with them again.

    Another Great Experience

    Posted 18 November 2025

    I’m a very happy repeat customer of Sebastian (Gal Group). He is easy to communicate with, honest, helpful, organised and fairly priced. The jobs he has completed for me were finished on time and to an excellent standard, with great attention to detail and workmanship. Highly recommend.

    Professional team

    Posted 13 November 2025

    We used Galgroup for the groundworks and a large concrete slab pour at our warehouse extension. The attention to detail and finish quality were excellent. Communication from start to finish was clear and professional. We’ll definitely be using them again in the future.

    Great company highly recommended

    Posted 08 November 2025

    Sebastian and his team did a great job on our kitchen extension. The team were always on time, they cleaned up after them, and had a lot of respect for other parts of our property while working there. Also, everyone was so polite and courteous. He helped us with the Build Over Agreement after we discovered a manhole in the garden, ie by liaising with the structural engineer and architect. His team are specialists in their fields. They are all very skilled and take a lot of pride in their work. The job was completed very efficiently and quickly, even through bad weather. Highly recommend!!

    Full property refurbishment and structural alterations

    Posted 07 November 2025

    We were doing a refurbishment of a flat where there was also some ground works and structural works to be carried out. After starting the job, we were let down by another builder, and Sebastian and his team came along and took over the job and saw it through all the way to the end. During this time, whilst on site, they carried out additional works including kitchen refurbishment and bathroom refurbishment. There were some painful elements to the job and Sebastian's team and colleagues always had an answer and a solution that was refreshing. Genuinely a fantastic team and would recommend.
