Hi, I'm looking for someone experienced to help me strip the old wallpaper from my living room walls. The wallpaper has been up for years and is quite stubborn, so I need a professional who knows the best techniques to remove it without damaging the plaster underneath. The room is about 20 square meters, and I would appreciate if you could bring your own tools and materials. Ideally, I want this done within the next week. Please let me know if you have experience with wallpaper removal and can work efficiently.
