Hi there, I have a small hole in a plaster wall that needs proper filling and patching. The hole is about the size of a 20-30 cm square, and I’d like a clean, seamless finish ready for painting. I’m hoping to find someone with experience in interior wall repair, using suitable filler, sanding smooth, and ensuring the surface blends with surrounding texture. Preference for tidy workmanship, minimal mess, and flexible timing this week. Supplies can be provided if needed, or you can bring what you typically use. Please share estimated time and any preparation I should do beforehand.
