Painting & Decorating- 13 Nov 2025
The team did a solid job on our extension. They were on time, kept the place organised, and stayed easy to reach throughout the project. The extension came out exactly as agreed and the finish looks clean. They also took care of a few extra jobs for us, including painting the exterior, laying new slabs in the garden, and putting down new grass. The whole place looks tidy and well put together now. I would be happy to use them again.
