A healthy lawn is the green welcome mat surrounding a home. It is the only plant material in the landscape that provides aesthetics, function, and recreation. While we enjoy many of these benefits, a healthy lawn requires maintenance. Over time, weather combined with traffic from lawnmowers, children, pets, and even vehicles push air pockets out of the soil, reducing its structure to a compacted substrate that prevents the absorption of water and nutrients. This results in grass that cannot thrive and grow.

Aerating a lawn is a common practice, but not one you must do at regular intervals, such as mowing and fertilizing. Rather, it is a solution to a problem. When your lawn starts showing symptoms of stress associated with compacted soil, start looking for a professional to aerate your lawn. Aerating during fall and spring is recommended, with fall being ideal. At this time, the weather is less extreme, preventing additional stress to an already-struggling lawn.

The national average cost range to aerate a lawn is $218 to $872. Most homeowners pay $545 for aerating a typical 10,900 sq.ft. lawn. However, prices vary widely, from as low as $21 for liquid aeration on a small lawn up to $4,531 or more for core aeration on a lawn of almost two acres.

What Does Aerating a Lawn Do?

If you notice your lawn looking dull or failing to thrive, aeration can help bring it back to life. Aeration removes physical barriers to the essential air, water, and nutrients that grass needs to survive and flourish, and it can be accomplished using various methods to suit your budget. No matter which method you choose, the basic principle is the same. Aeration allows air, water, and nutrients to be absorbed by the roots of the turfgrass, resulting in a healthier, more vigorous lawn.

Lawn Aeration Cost per Square Foot

The national average cost of lawn aeration per square foot is $0.05. For small yards, the cost is usually based on the square footage. For larger yards, the cost is usually per acre, not per square foot. For an average lawn of about 10,000 sq.ft., many professional lawn care companies charge a flat rate that varies from $120 to over $400. An acre is 43,560 sq.ft., and most professionals charge $480 to $650 per acre, which averages to $565 per acre.

Aeration Prices by Type

There are three types of lawn aeration: liquid, spike, and core. Core aeration is often recommended as the most effective type because it physically removes the soil, relieving the compaction issues affecting the lawn. See average costs for each type in the table below:


Aeration Prices Chart


TypeAverage cost
Liquid$0.015 per sq.ft.
Spike$0.03 per sq.ft.
Core$0.05 per sq.ft.


Liquid Aeration

Liquid aeration is the least expensive option because it does not involve the use of heavy equipment. This aeration type uses the chemical ammonium lauryl sulfate to break down the soil to create air pockets in the lawn. Since it is a liquid, it can be applied over the entire surface of the lawn, rather than just the every few inches offered by mechanical methods. The average cost of liquid aeration is $164 for an average lawn of 10,900 sq.ft.

Spike Aeration

Spike aeration uses equipment that has solid metal tines to push holes into the ground without removing any soil. This method is best for creating holes in un-compacted soils so that the fertilizer has better access to the roots. Critics of this method point out that it does not alleviate soil compaction because it merely pushes soil down and out, causing additional compaction around the spikes. The average cost of spike aeration is $327 for an average lawn of 10,900 sq.ft.

Core Aeration Cost

Most lawn care professionals use a machine called a core aerator that employs hollow metal tines to pull small “cores” or “plugs” out of the soil. This process results in holes that are spaced about 3” to 5” apart, 2” to 3” deep, and 0.25” to 0.75” in diameter. This type of aeration is regarded as the most effective because it physically relieves soil compaction by removing the soil in a methodical way, which none of the other methods do. Removing soil permits the roots to expand into the holes where they can access nutrients, air, and water directly. Core aeration beneficially changes the soil surface, creating places for capturing water runoff and gives your grass room to breathe and grow better. The average cost of core aeration is $545 for an average lawn of 10,900 sq.ft.

Factors Affecting the Costs of Aerating a Lawn

Among the most important factors impacting the costs of aerating a lawn are the lawn quality and size, preparation of the lawn before the aeration process, and whether you include add-ons like fertilizers or seeding.

Your lawn service professional can work with you to prepare the lawn for aeration, which increases your cost. Alternatively, you may do it yourself. Prepping a lawn for aeration includes several time-sensitive tasks. At least one week prior to using aerator equipment on the lawn, local utility companies must place flags over buried utility lines. One to two days before aerating, apply at least one inch of water to the lawn if it is dry. Obstacles must be removed from the lawn, and all sprinkler heads must be marked.

Most lawn care companies offer add-on services that you might decide to factor into your overall cost. These include applying compost, fertilizer, and grass seed to the newly aerated lawn. While not required, these services are beneficial and will greatly increase your chances of successfully restoring your lawn to a healthy state.

Cost to Aerate and Overseed a Lawn

Overseeding is the process of scattering grass seed over soil and then waiting for it to germinate. While this description leaves out some details, one important way aeration complements overseeding is that it prepares a “seedbed” that increases the probability that the grass seeds will germinate. Also, overseeding ensures desirable grass seeds fall into the holes where undesirable weed seeds might migrate. The average cost to aerate and overseed a lawn is about $800.

Cost to Dethatch and Aerate a Lawn

Thatch is a spongy residue that accumulates between the soil and grass leaves. Some thatch is perfectly normal and even beneficial because it prevents compaction and erosion of the underlying soil. However, when excess thatch accumulates, it causes several issues, such as making mowing difficult, attracting insects, and introducing disease problems. Dethatching is an activity best suited for the spring, and many lawn care companies combine it with their lawn aeration service. It is a process that should occur before aerating. If the thatch is more than one inch deep, it must be removed in stages, which might take more than one day. The average cost to dethatch and aerate a lawn is about $945.

How to Tell if Your Lawn Needs Aeration

Your lawn will show the signs of soil compaction even before you examine the soil. The grass will not be as green as it once was and might have uneven growth. Water will run off the surface of the lawn and into the street. Or, it might puddle in spots instead of absorbing into the ground. Soil in areas that receive heavy traffic naturally become compacted over time and will show bare spots and areas that are hard and dry. In addition, a buildup of thatch might be present. Whenever your yard exhibits any of these symptoms, it is time to hire a professional to aerate your lawn.

Benefits of Lawn Aeration

The main benefit of lawn aeration is to provide relief to turfgrass trying to grow in compacted soil. If the soil has a healthy structure that allows air, water, and nutrients to reach the roots, then the grass growing in it will show all the signs of being healthy. In this case, aeration is not needed. Aeration is beneficial when the grass starts to decline, and that decline can be attributed to compacted soil. Also, aeration is a cost-effective way to maintain struggling turfgrass rather than removing and replacing it, which can cost over $30,000 for an average-sized lawn. Other benefits of lawn aeration include improving turf health, reducing thatch accumulation, decreasing soil density, modifying the pH, germinating grass seeds, lowering water runoff, and preparing the grass for winter.

When to Aerate a Lawn

The ideal time to aerate a lawn is when the turfgrass is actively growing, with four to six weeks left in its growing season. However, out of all four seasons, it is best to aerate in the fall because it is the time of year with the lowest prevalence of weed seeds. In other words, punching holes in the lawn to collect water, air, and nutrients provides a nice environment for weed seeds to germinate, which are prevalent in the spring. When aerating in the spring, aim for late spring, when the weeds are growing, but before they start producing seeds. For most United States Department of Agriculture (USDA) plant hardiness growing zones, this is around the Memorial Day holiday.

Enhancements and Improvement Costs

Tree Trimming and Pruning

Lawn care companies that aerate yards might also offer tree trimming as a service. Limbs that are too wide can shade out your grass, diminishing the appearance of your lawn. Selectively pruning tree limbs can increase light penetration to the grass. This costs between $75 and $1,500.

Tree and Shrub Maintenance

Trees and shrubs can reduce available light to turfgrass and compete with the lawn for water and nutrients. When they are not properly maintained, lawn problems can occur. This has a cost of $160 to $2,225.

Lawn Mowing

After fixing soil compaction problems by aerating, consider maintaining your turfgrass with a lawn mowing service. A good mowing service knows what height to mow your variety of turfgrass to and how to keep it looking nice, which increases the curb appeal of your home. The cost of a lawn mowing service is between $25 and $150 per visit.

Sprinkler System Installation

Aeration can damage sprinkler heads, but if the sprinkler system was installed correctly, a core aerator should not damage the underground pipes. The absence of a sprinkler system can lead to a neglected lawn. The cost of installing a sprinkler system is $2,200 to $11,000.

Additional Considerations and Costs

  • Aerating your lawn as a DIY project might reduce your costs, but it can also increase your level of aggravation and time away from other, more important things. Hiring a professional saves time and increases the probability of a positive result.
  • If your lawn is dry, water it one to two days before aeration. Core aerators are prone to clogging, which is more likely to happen on a dry lawn.
  • When overseeding, plan to stay off the lawn for at least one month. Also, be sure to water the grass lightly and frequently to encourage germination and establish the new grass. About two weeks after germination, slowly reduce the frequency of watering to encourage the seedlings to develop deep root systems.
  • Weeds are a problem in lawns no matter where you live. The best defense against lawn weeds is dense, healthy turfgrass. After aerating, keep weeds at bay by watering thoroughly and infrequently (on established grass), fertilizing often, and mowing properly.

FAQs

  • How long does it take to aerate a lawn?

The estimated time it takes to aerate a lawn is about two weeks, including the preparation time until the end of the recommended follow-up activities.

  • How often does my lawn need to be aerated?

Unlike other lawn care activities, such as mowing and fertilizing, aeration is situational. You only need to aerate when your lawn shows signs of soil compaction.

  • Can I mow my lawn after aeration?

After aerating and especially if you overseeded, you should stay off your lawn for at least one month. Mow your lawn before aerating, not immediately after.

  • Is it better to fertilize before or after aeration?

It is better to fertilize after aeration because the holes will make it easier for the fertilizer to reach the grass roots.

  • Should I aerate my lawn in summer?

Summer is not the best time to aerate your lawn. However, depending on the grass type and your climate, early summer is fine. Aerating a lawn during times of extreme heat can cause your lawn to dry out and possibly suffer extensive damage.

  • Should you fertilize your lawn after aerating?

Yes, you definitely should. This gives your grass a chance to receive the nutrients it could not access due to the physical barrier of compacted soil.
