We contracted Gesas-Ambition to carry out basement renovation works at our property in New Cross, SE London. This included internal structural alterations, new drainage associated with bathroom and kitchen, carpentry and finishes. 

From the onset, they were very organised in their tender submission, which was thorough and competitive. We were impressed with their management of the project, communication for the duration, and ultimately, the final product. 

We would certainly work with them again and are pleased to recommend them.

Basement renovation works

Great team. Very efficient, friendly and thorough and did a great job cleaning/tidying away after. Also completed the work for a good price!

Highly recommend

From the initial consultation to the final handover, Sebastian and Jhon along with the Gesas-Ambition team were nothing short of outstanding. We approached them for a major overhaul of our dated family home, which involved gutting and redesigning the interior spaces while adding a modern driveway . Despite some unexpected challenges  like hidden structural issues and weather delays during the driveway phase, they handled everything with professionalism,  and innovative solutions that stayed within our budget. We’ve already recommended them to neighbors and would use them again in a heartbeat

Complete refurbishment of a 3- bedroom bungalow house, including full kitchen and bathroom remodel

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.

Shell for 3x6m extension

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.

Another Great Experience

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.
