Hiring a Yard Cleanup Service Cost. The cost of a professional yard cleanup depends on the size of your property, the number of trees, and whether the leaves and debris can be left curbside or must be hauled away. For a half-acre lawn with a fair amount of trees, budget anywhere from $200 to $500. Saves time - Hiring a professional yard cleaning service saves you a lot of time and effort. You can spend the time you would have been working in the yard doing something a little more fun.
We pay $75 per month for someone to mow the lawn, trim stuff, and generally tidy up. They come twice a month. But I'd imagine this massively depends on: 1  the size of the lawn. 2  who provides the lawnmower. 3  who provides the fuel for the lawnmower.  the country you live in.
