Spring cleaning is no fun, which means many of us are willing to leave the task to a professional. But how much should you shell out for a one-time deep clean? That depends. In a big city like Toronto, $35 to $45 per hour for a scrub-down is the going rate, says Melissa Maker, founder of Clean My Space. But if you live in a smaller city, you’re in luck: Rates as low as $20 an hour are not unheard of. The total cost will vary with the size and relative filth of your heap. A small condo might only require a few hours to clean, while a 5,000-sq-ft home could take all day and cost $300 or more.
