What does fall aeration include?
Compacted Maine soil is why a lawn looks tired even when you mow on time. Clay, summer traffic, and last winter's plow piles seal the surface. Water sits. Roots stay shallow.
We pull soil cores across the lawn so air, water, and fertilizer reach the root zone. Then we overseed with a mix that holds up to Greater Portland summers and shoulder-season cold.
The visit is scheduled in a set week. Jack's crew shows up in that window, finishes the pass, and leaves the plugs to break down. You get a thicker stand by spring, not a weekend rental and a guess.
- Core aeration with commercial equipment
- Overseeding matched to sun, shade, and soil
- Optional starter fertilizer or light topdress
- Watering plan for the first two weeks
- Same-week free estimates while fall slots last
If thatch is thick, pair this with fall cleanup and dethatching. For the difference between the two jobs, read dethatching vs aerating for Maine lawns.
When should you aerate in Maine?
Book September and October first. Soil is warm, nights drop, and fall rain does the watering you would otherwise stand outside to do.
Wait much past late October and seed sits cold. Book too early in August and heat can cook the new grass. We tell you if your week is still in the window.
Serving Portland, South Portland, Cape Elizabeth, Falmouth, Scarborough, and nearby towns. See all lawn care services, or call if you want aeration on the same visit as a fall cleanup.

I can’t recommend tbe Garden Guys enough. They have helped me transform my entire yard. When I moved into my house, the grass was extraordinarily thin and there were invasive trees. Now I have a beautiful lush green yard, beautiful flowers, and healthy native trees. Thank you Jack and team!
( FAQ )
Aeration and overseeding questions
When should you aerate a lawn in Maine?
Late August through October is the window. Soil is still warm, nights cool down, and fall rain helps seed germinate before winter. Spring aeration works in a pinch; fall is the stronger play for Southern Maine lawns.
What does aeration and overseeding include?
We core-aerate the lawn, break up the plugs as needed, spread a Maine-appropriate seed mix, and walk you through watering. Fertilizer or a light topdress can be added when the lawn needs it. No surprise add-ons after the visit.
How much does aeration cost in Southern Maine?
Most Portland-area lawns land between $175 and $850 for aeration plus overseeding, depending on size and soil. The range on this page is typical, not a quote. We price the job on site and it is free to estimate.
Why is fall better than spring for aeration?
Fall seed has less weed competition and more consistent moisture. Spring work can still help compacted soil, but summer heat often hits before new grass is established. We book fall first for that reason.
Do I need to water after overseeding?
Yes. Keep the seedbed evenly moist for about two weeks. Short, frequent waterings beat one deep soak while seed is germinating. We leave simple instructions for your property.
What is the difference between dethatching and aerating?
Dethatching (power raking) lifts the mat of dead stems on top of the soil. Aeration punches cores so air, water, and seed reach the root zone. Many lawns need both. Read our guide on dethatching vs aerating, or book a fall cleanup if thatch is the bigger problem.
