Extensions- 17 Nov 2025
Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

Groundwork & Foundations- 7 Feb 2026
Oli carried out the groundworks and demolition at my property and was on site every day with his crew, fully committed and hands-on throughout the job. I am an architect, and this was work on my own home, so my expectations were high. Oli met those expectations fully. He has a strong knowledge of groundworks and demolition, works carefully and methodically, and you can tell he genuinely enjoys what he does and takes real satisfaction in delivering the work exactly as required. He was always in a good mood, easy to communicate with, and a pleasure to have on site. I enjoyed discussing the project and hearing about other jobs he has completed over his 23 years of experience, which clearly shows in the quality of his work. I would highly recommend Oli for any groundworks or demolition works.

Old artex ceilings in bedrooms, hallway stairs and landing skimmed to flat with a high standard, finished off and decorated white to a high standard. A bedroom was given a full redecoration too, going from a faded, outdated look, to a crisp modern one. I am very happy with the work and everything is to a high standard.

Extensions- 1 Feb 2019
Extremely satisfied. He happily goes the “extra mile” and his charges for such additional work are reasonable. Inevitably the odd unanticipated item arises in the course of the work and he discusses the options rather than making up our minds for us. His dictum that he does not leave a job for another before the first job is finished is reassuring - and fact. We have been happy to contract further work to him - including hard landscaping - on the completion of the original extension work, and are equally impressed with his performance in this.
