We always intend to retexture drywall to match the rest of your house after wallpaper removal is complete. Once in a great while after wallpaper is removed the drywall texture is unharmed and ready for paint. In this case we only charge for the removal. On the other hand, we charge on how the wallpaper is going to come off and we can determine that upon visit. We only steam wallpaper using no chemicals, only hot water. This is the best and most effective way for us. After wallpaper removal, the drywall is completely smoothed out to give it a clean and new surface. This is needed for any and all textures. After drywall smoothing is complete it then is textured to match existing texture in home. Keep in mind that floor, ceiling and walls not being involved are totally prepped off with plastic prior to skim coating.
