Extensions- 28 Jan 2026
Dan came round at short notice to discuss our plans for a garden room; he provided a very detailed itemised quote so we knew exactly what we would be paying for. Before committing we had multiple questions for Dan and he (very patiently!) provided clear and detailed answers. We set up a WhatsApp group with Dan and his communication with us throughout was brilliant. He kept us updated with the plan/schedule for each day, he sent us before and after pics to show progress and was always quick to respond in detail to any of our queries. We are really pleased with the finished build, it ran smoothly and it finished on time. We really appreciate Dan, Chris, Cam and Alfie's hard work and would certainly use them again for any future projects.
