How much does aeration & overseeding cost?
Typical
$145
Most pay $75–$250 per service
Standalone core aeration averages about $145 for a typical quarter-acre lawn, with most jobs falling between $75 and $250. Add overseeding, which most people do at the same time, and you're looking at roughly $0.08 to $0.20 per square foot on top, pushing a combined job into the $250 to $700 range on an average lawn.

What affects the cost
Lawn size
Priced per square foot or by lot size. A 5,000 sq ft lawn runs roughly $50–$100 to aerate, a quarter acre $75–$150, and a full acre $250–$500.
Aeration method
Core (plug) aeration is the standard and runs $75–$250 for a typical lawn. Liquid aeration is often a bit cheaper at $0.02–$0.05 per square foot but works differently and isn't a one-to-one swap.
Overseeding add-on
Most people overseed right after aerating since the holes give seed a place to settle. Budget another $0.08–$0.20 per square foot, which on a 10,000 sq ft lawn is $80 to $200 extra.
Number of passes
Badly compacted or clay-heavy soil sometimes needs the machine run twice in a crosshatch pattern. That doubles the aeration labor and raises the bill.
Labor and equipment
Crews charge roughly $45 to $75 an hour, and a walk-behind aerator is heavy, awkward equipment. Lawns the machine can't easily reach or maneuver around cost more.
Location
Northeast and West Coast metros run higher on labor. A quarter-acre aeration that's $80 in Austin can be $120 to $150 in New York or Seattle.
Core aeration cost by lawn size, before overseeding (2026)
| Lawn Size | Approx. Square Feet | Aeration Cost |
|---|---|---|
| Small | 1,000 sq ft | $15–$30 |
| Modest | 5,000 sq ft | $50–$100 |
| 1/4 acre | 10,890 sq ft | $75–$150 |
| 1/2 acre | 21,780 sq ft | $130–$250 |
| 1 acre | 43,560 sq ft | $250–$500 |
| 2 acres | 87,120 sq ft | $480–$650 |
Cost by region
The highest rates, driven by metro labor costs in cities like Boston and New York. Cool-season lawns here are best aerated in early fall, so demand bunches into a short window that keeps prices firm.
The most affordable region. Warm-season grasses like Bermuda and Zoysia get aerated in late spring and early summer when they're actively growing, and lower labor rates in cities like Houston and Atlanta keep the total down.
Mid-range pricing with a fall aeration season for the region's cool-season turf. Heavy clay soils common across the Midwest sometimes call for a second pass, which nudges costs up.
A broad range. Coastal markets like Seattle and Los Angeles carry higher labor costs, while in much of the arid West, smaller irrigated lawns mean smaller aeration bills.
What aeration actually does for your lawn
Over time soil gets packed down from foot traffic, mowing, and rain, and a layer of thatch builds up at the surface. Compacted soil chokes off the air, water, and nutrients roots need. Core aeration pulls thousands of small plugs out of the ground, opening up channels so the lawn can breathe and drink. You leave the plugs on top to break down on their own. It's one of the higher-return things you can do for a tired lawn, and it's cheap relative to the alternative of tearing everything out and starting over with sod.
Why aeration and overseeding go together
Aerate and you'll usually overseed in the same visit, and for good reason. The holes the machine leaves are perfect little pockets for new seed to drop into, get good soil contact, and germinate instead of drying out on the surface or washing away. Overseeding fills thin and bare patches and crowds out weeds before they get a foothold. The combo runs about $250 to $700 on a typical lawn once you add seed at $0.08 to $0.20 a square foot to the aeration. On a 10,000 sq ft yard, that seed layer alone is $80 to $200, and it's money well spent if the turf is patchy.
Core versus liquid aeration
Core aeration is the version most people mean, and it's what crews show up to do by default. A machine physically removes soil plugs, which is the most direct way to relieve compaction. Liquid aeration sprays a solution that's supposed to loosen soil chemically over time. It's gentler on the lawn's appearance, doesn't leave plugs scattered around, and runs a touch cheaper at $0.02 to $0.05 per square foot, but it works more slowly and won't fix severely compacted ground the way pulling cores will. For a heavily trafficked or clay-bound lawn, core is the safer money.
Reading a per-square-foot quote
Aeration quotes get confusing because the per-square-foot number swings depending on what's bundled. Bare core aeration can be as little as $0.02 to $0.03 a square foot, but you'll also see figures of $0.10 to $0.20 a square foot quoted, and those almost always fold in overseeding, fertilizer, or a premium service package. Neither is wrong; they're measuring different jobs. The cleanest way to compare bids is to ignore the per-foot rate and ask each company for a flat total on your specific lawn, with overseeding listed as its own line item.
Timing it right by grass type
Aerate at the wrong time and you've wasted the money. Cool-season lawns up north and across the Midwest, think fescue and Kentucky bluegrass, do best aerated in early fall when they're growing and can heal before winter. Warm-season lawns across the South, like Bermuda, Zoysia, and St. Augustine, want it in late spring or early summer at the start of their active growth. A landlord with rentals in two climates can't run the same calendar in both, and a crew that aerates a dormant lawn is charging you to stress it for nothing.
Ways to save on lawn & garden
- Bundle aeration and overseeding in one visit; doing them separately means paying twice for the crew to show up.
- Schedule in the off-peak shoulder of the season when crews have open slots and may discount to fill the calendar.
- Skip a second pass unless your soil is genuinely compacted; one pass is plenty for an average lawn.
- Rent a walk-behind aerator for a small, flat lawn if you're comfortable handling the machine yourself.
- Combine several rental properties on one service day so the crew quotes a route rather than individual trips.
Frequently asked questions
How much does lawn aeration cost?
Standalone core aeration averages about $145, with most lawns falling between $75 and $250. A small 5,000 sq ft lawn might run $50 to $100, while a full acre lands at $250 to $500.
How much does overseeding add to aeration?
Overseeding typically adds $0.08 to $0.20 per square foot. On a 10,000 sq ft lawn that's $80 to $200 extra, bringing a combined aeration-plus-overseeding job to roughly $250 to $700.
Is core or liquid aeration better?
Core aeration physically pulls soil plugs and is the better choice for compacted or clay-heavy lawns. Liquid aeration is gentler and slightly cheaper at $0.02 to $0.05 per square foot, but it works more gradually and won't relieve severe compaction as effectively.
When should I aerate my lawn?
It depends on your grass. Cool-season lawns in the North and Midwest do best in early fall, while warm-season southern lawns like Bermuda and Zoysia should be aerated in late spring or early summer during active growth.
How often should a lawn be aerated?
Most lawns benefit from aeration once a year. High-traffic lawns or those on heavy clay soil may need it annually, while a healthy lawn on loose, sandy soil can often go every two to three years.
Can I aerate my lawn myself?
Yes, you can rent a walk-behind core aerator from a home improvement store. It's heavy, awkward equipment, so DIY makes the most sense on a small, flat lawn. For larger or hilly lots, hiring a crew is usually worth the cost.
