Lawn Aeration & Overseeding in Evanston, IL
Core aeration and overseeding to reduce compaction, improve drainage, and fill in thin or patchy lawns.
Homeowners and businesses in Evanston trust River Fall for lawn aeration & overseeding because we show up, do the work right, and stand behind it. Same crew from estimate to completion: no subcontractors, no shortcuts.
Over time, lawn soil compacts — especially in yards with heavy foot traffic or clay-heavy ground. Compacted soil blocks water, air, and nutrients from reaching the root zone, and the lawn thins out as a result. Core aeration pulls small plugs of soil from the ground, opening channels that allow roots to breathe and grow deeper.
We use core (plug) aeration, not spike aeration. Spike aerators push the soil aside rather than removing it, which can make compaction worse over time. Core aeration pulls actual plugs, which break down on the surface and return organic matter to the lawn within a few weeks.
Overseeding immediately after aeration takes advantage of the open soil channels — seed makes direct contact with loosened soil and germinates faster. Fall is the best window: soil temperatures are still warm enough for germination, air temperatures are cooler, and there's typically more rainfall. Most lawns see visible improvement within three to four weeks.

- Plugs break down naturally — no cleanup needed
Common Questions
When is the best time to aerate and overseed?
Fall — typically late August through October in Chicagoland. Soil is still warm enough for seed germination, but air temps are cooler and there's typically more moisture. Spring aeration is also possible but fall is preferred.
Do I need to water after overseeding?
Yes. Consistent moisture for the first two to three weeks is critical for germination. We'll walk you through a watering schedule at the end of the visit.
Do you use core aeration or spike aeration?
Core aeration only. Spike aeration pushes soil aside rather than removing it, which doesn't address compaction the same way.
How often should I aerate my lawn?
Once a year is typical for most Chicagoland lawns. Lawns with heavy clay soil or high foot traffic may benefit from twice a year.
