Painting & Decorating- 10 Jul 2026
We have just moved from Australia into a new house. There is a lot that needs doing. The team were great! I asked them to do considerably more than they were expecting to do. I certainly moved the goal posts several times. Nothing was too much trouble! They were very helpful. Thank you for all your hard work.
