I have a small hole in the plasterboard from a removed nail that needs repairing. It’s in a living room wall, about the size of a fist. I’d like the repair to be smooth and ready for paint, with minimal disruption. Please include plaster filling, sanding, and a light touch-up paint to match the surrounding colour. I’m hoping for a tidy job that blends in well. Ideally, you can bring or supply the patching material and paint that matches the current shade. If you need to inspect first, I can arrange a quick visit.
