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!

Dmitry

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.

Thanks to Michael and the team for a great job rendering the chimney breast in the attic. Quoted and works completed in less than 48hrs. Not the cheapest of the quotes I received, but went with the positive reviews and wasn't disappointed.

John and the team did an outstanding job. It was easy to work with John and he was very knowledgeable, and provided very sensible advice. Other people quoted work which was over-the-top or wouldn't have solved the problem but John got right to the issue in a no-nonsense way. Quality of the work undertaken was very good, considering the age of the building and complexity. Would recommend.

We had them in to install insulation in our upstairs floor, replace the sub floor, replace some lights, install a loft hatch, and board out our loft. On top of this they discovered a problem in our roof that they fixed. We were incredibly impressed by all of the staff that attended on site. They were friendly, polite at all times, and worked really hard, to a high standard. I couldn't recommend James and his team more, and we've already started talking to them about a further project.

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.

When evaluating the builders it was important to us that we found somebody who was professional, reliable, and detail-oriented.

Fatjon did the most fantastic job installing my bespoke Plantation Shutters into the bay window of my Victorian cottage. He was punctual, considerate, polite & the level of his craftsmanship was first class. The shutters look amazing & so much better than I had expected because of his finishing touches. In fact I asked him back the next day to do some other work for me. I honestly can’t recommend him highly enough.
