Calculate the cost by multiplying the size of your lawn by the price per square foot for the type of aeration you chose. For example, if your lawn is 5,000 square feet and the price per foot is $0.05 for core aeration, the cost will be $250 (5,000 x $0.05).

Is lawn aeration necessary? Almost all lawns will benefit from aeration, and a great lawn demands it. That said, most lawns do not need it. Lawns suffering from heavy foot traffic, excessive thatch (>1 inch thick) or grown on heavy soils will benefit most.

But if your grass is healthy and thriving and hasn't been impacted by a lot of equipment or foot traffic, it likely doesn't need aeration. Once annually is usually enough in most cases, and for healthy lawns that receive regular maintenance and are performing well, every two to three years may be sufficient.

Core aeration should be performed every one to two years on lawns that receive heavy foot traffic. Otherwise, aerating every two to four years on home lawns is sufficient. Soil plugs can be left on the surface of the lawn. They will decompose in a couple of weeks.
