Extensions- 9 Feb 2021
From the beginning of meeting Gareth and Tristan they are friendly and professional, they came to our home to build an extension and knock a wall down. They are an amazing pair. They are very skilled at what they do and they work continuously all day. They would clean up after themselves and were very unique with ideas for the build. If they came across an issue it was always resolved very quickly and affectly. They are very pet friendly as that can be a worry to pet owners when doing a big build. They also kept to their time scale even if that meant working late into the evening, but always arrived on time and were never late. Nothing is too much for them and it was a pleasure having them in our home. The result is spectacular and we are very pleased with what they have done. I would certainly recommend them to other people as they stand our from the rest.

Hard Flooring- 16 Jun 2026
I chose Tom from a few quotes because he did the most thorough inspection and am so glad I did. The kitchen subfloor needed some extra prep work to get it level, and Tom handled it with ease. The communication was excellent, the job was completed right on schedule, and the new flooring is perfectly fitted. Highly recommended workmanship.
