Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!

Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

Thank you Ionut and the team, im so happy to have a space where I can be proud of! I needed the existing paving slabs removed and to put in place decking, artifical grass, and planters put in. They provided the materials and kept me informed in the process. They are hardworking and I saw a huge difference for every day they came. Thank you once again for taking on this project, and I'm so happy this has all been done before summer has started! Would hire again!

Serjan skimmed and plastered a difficult bedroom ceiling in my Victorian house, which I am renovating. I highly recommend serjan He responded to my request for a quote very quickly on a weekend, quoted the next day and then had completed the job all within a week. Serjan was highly professional and respectful whilst working (the whole family was home). This is not the first plastering I have had done, but I can see that he is highly skilled in plastering. A five star review is well-deserved.

Ian came round to take a look at a damp patch that had started showing up on one of the utility room walls. He turned up on time, was really friendly, and clearly knew what he was talking about. He gave everything a proper check over and explained what was likely going on in a way that actually made sense. He didn’t try to make a mountain out of a molehill or push for any unnecessary work—just gave honest, practical advice on what to do next. Really appreciated how straightforward and helpful he was.

Endrit and his team were wonderful to work with - friendly and professional and nothing was too much trouble for them, despite me changing aspects of the kitchen renovation and install during the process. They went above and beyond to ensure that everything was perfect and that I was happy with all aspects. My new kitchen looks amazing and I can't recommend Endrit and his team highly enough - I have already recommended E Saint George to friends and will be getting them back to install my bathroom.
