Aerating
Dethatching

Dethatching a lawn is where a big tool called a Power Rake goes over your lawn and uses a rake like blade to pull up all of the old thatch and moss. Then the landscaper rakes the thatch up and hauls it away. This is a much longer process and has more potential to do damage. Typically, we do not recommend dethatching unless you have a variety of grass that is prone to creating large amounts of thatch or a thick layer of moss. Instead, we recommend aerating.
Cost
The cost for lawn aeration and for dethatching, if necessary, can vary. Generally speaking, aeration runs $120 and up, while dethatching is usually around $300 and up.
