Risk: Moderate

Starting a window cleaning business from scratch can be risky, especially for someone who can't afford to lose money. Potential losses could include money invested in equipment, marketing, and training, as well as time and energy spent on building the business. Beginners may spend money on equipment and advertising without seeing immediate returns, leading to financial losses. There are startup costs ranging from $500 to $2,000 for equipment and marketing that may not pay off if the business doesn't attract enough clients. Online discussions often mention challenges with finding customers and competition affecting profitability. I'd rate the risk a 2 out of 3 because there is a moderate risk of losing money and time, particularly if marketing efforts don't yield desired results.
