The answer to the cost of aeration in your area is that it can vary quite a bit depending on several factors. In general, you can expect to pay anywhere from $50 to $200 for a standard lawn aeration service. The exact price will depend on the size of your yard, the complexity of the job, and the going rates in your local market.
Lawn aeration is an important maintenance task that helps improve soil health and water drainage, so it's generally recommended to have it done annually or every couple of years. While you can rent an aerator and do it yourself, many homeowners choose to hire a professional landscaping company to handle it for them. Getting quotes from 2-3 local providers is the best way to determine the typical cost in your specific area.
