Core aeration relieves the compaction Iowa clay builds up, and overseeding fills thin spots while the holes are open. Done together in the right window, it is the biggest single upgrade a tired lawn can get.
Much of the soil around Cedar Falls and Waterloo carries enough clay that foot traffic, mowers, and time press it tight. Compacted soil starves roots of air and water, and the lawn responds by thinning. Core aeration pulls thousands of small soil plugs, opening channels for air, water, and nutrients to reach the roots. The plugs stay on the lawn and dissolve back in within a couple of weeks, returning soil and microbes to the surface.
Iowa State University Extension points to late summer as the prime time: aerating and overseeding between mid-August and mid-September gives new seed warm soil to germinate in and a long stretch of cool fall weather to establish before winter, while annual weed pressure is falling instead of rising. Spring (April) is the backup window for aeration alone, but fall wins for seed. The aeration holes are exactly where you want seed to land, which is why the two services are done together in one visit.
Pricing follows lawn square footage and how much seed the thin areas need. Pairing aeration and overseed in one visit costs less than booking them separately.

Soil cores pulled by the aerator. Leave them where they fall: they break down in about two weeks and return soil and microbes to the surface. Do not rake them up.
Keep traffic light and the top inch of soil moist for the first two weeks, then mow normally once the new grass reaches about 3 inches. We give you a simple watering plan at the visit.
