Interior walls and ceilings
Walls and ceilings together, because a fresh wall makes an old ceiling look worse.
Doing walls without the ceiling is the most common regret on an interior job. The ceiling reads as dingy the moment the walls are clean, and coming back for it later means masking walls you just paid to have finished.
Usually part of a larger job — see interior house painting, or ask for a free estimate. For one room, a photo is usually enough.
