What our customers say about us
"George and Josh were really easy to deal with, from getting a quote through to finishing our new decking. We’re pleased with the high standard of their work, their professionalism and how tidy they were. We would definitely look to use them again in the future."
Oli Hill
"We used Watson and Dalton after being recommended to use them by my daughter. They built a 14 metre Venetian fence at the back of our garden. Not only were they superb but the were so knowledgable in what they were doing. They are very talented and we are more than happy with the finished product."
"Josh & George have helped transform my garden. They were responsive and supportive offering practical solutions while maintaining the integrity of my ideas. They had a high standard of workmanship and positive work ethic. Thank you for all your hard work guys I couldn’t be more delighted with the results. I can’t wait for the garden to grow into itself around the foundation and structure you built as a solid base for a beautiful garden."
Alison Manning
"Josh made our beautiful table for us where this room is now the main place in our house that we use. We showed him some inspiration of what we wanted using some pictures and he knew exactly what to do. He always kept us in the loop of how it was going and when the table would be ready. As you can see from the picture the table is beautiful and completes the room. Josh is very approachable and took the time to understand our needs and what we wanted within our price range. Everyone who comes into the house always comments on how stunning the table is and asking us where we got it from. 10/10 - 100% would recommend!"
Sophie Daniels
"Josh and George were recommended to me by a friend. They laid a patio and built a pergola for my garden and even gave me some extra insight on landscaping options for the future. They were both professional, punctual and extremely hard working. Their attention to detail and wide skill set is very impressive. I have already booked for them to return and build me a fence."
