Beginner friendly: Easy to start

Starting a window cleaning business can be relatively easy for beginners with no special skills or background. Online resources like YouTube tutorials and forums provide valuable information on techniques, equipment, and marketing strategies. The startup costs range from $200 to $500 for basic supplies. With consistent effort and quality service, beginners can start earning profits within 2 weeks. I'd rate it a 3 because the business model is straightforward, the initial investment is affordable, and demand for window cleaning services is generally high.
