Lawn aeration in Ottawa
Neiber core-aerates a typical Ottawa lawn for $60 ($50 for members), priced on the size of the lawn we actually cover, so a townhouse strip costs less and a big corner lot costs more - always shown before you book. Core aeration pulls plugs of soil out of the lawn so water, air and fertiliser reach the roots - the fix for the compacted clay most Ottawa yards sit on. The two best windows are late April to early June and late August to mid October. Members whose neighbours book the same day save a further 10 to 15%.
Why Ottawa lawns need it
Most of this region sits on heavy clay. Clay compacts under foot traffic, snow load and spring melt, and compacted soil sheds water instead of absorbing it - which is why a lawn can be watered all summer and still thin out.
Core aeration is the mechanical fix: pull thousands of small plugs so the root zone can breathe. It is the highest-leverage hour your lawn gets all year, and it makes everything you do afterwards - overseeding, fertilising, watering - actually work.
Core aeration, not spike aeration
We pull cores, we do not poke holes. Spike aerators push soil sideways and compact the walls of the hole, which on clay makes the problem slightly worse. A core aerator removes soil entirely and leaves the plugs on the surface to break down - that is the version worth paying for.
When to book
Spring: late April to early June. Soil is moist, roots are moving, and the lawn has the whole season to fill in.
Fall: late August to mid October. Usually the better of the two - maximum root recovery before winter, and the ideal moment to overseed straight into the holes.
And an honest note: a healthy lawn with good soil does not need aerating every year - every 2 to 3 years can be plenty. Annual aeration earns its keep when the soil is compacted (clay, heavy foot traffic, dogs and kids) or when you are pairing it with overseeding or topdressing, where the open cores make the whole treatment work. Coring an already-excellent lawn just to do it is disruption without a payoff, and we will tell you so.
Before we arrive
- Mark your sprinkler heads if you have irrigation - we ask this when you book and flag it on the crew's job sheet, but visible markers are the real safeguard.
- Mow first, a little shorter than usual, so the machine reaches soil cleanly.
- Water the day before if it has been dry. Moist soil lets the tines pull full plugs; bone-dry clay just bounces them.
- Tell us about fresh sod or seed - if it went down inside the last two months the roots have not set and we should wait.
- Overseed right after for the best result. The open holes are the best seed bed you will get all year.
Frequently asked questions
How much does lawn aeration cost in Ottawa?▾
Neiber charges $60 at retail and $50 for members to core-aerate a typical Ottawa lawn - a front and a back lawn of average size. The price follows the ground we cover, so a small city lot is less and a large one is more, and you see your own figure before you book. Members whose neighbours within 1 km book the same day save a further 10 to 15%.
When is the best time to aerate a lawn in Ottawa?▾
There are two good windows: late April to early June in spring, and late August to mid October in fall. Fall is usually the better of the two because the lawn gets maximum root recovery before winter and you can overseed straight into the holes.
What is the difference between core and spike aeration?▾
Core aeration removes plugs of soil entirely; spike aeration just pushes holes into the ground. On Ottawa's clay soil, spiking compacts the sides of each hole and can make compaction slightly worse. Neiber pulls cores.
How often should I aerate?▾
It depends on the lawn, and we will tell you straight. A healthy lawn with good soil structure and no compaction can go 2 to 3 years between aerations. Annual aeration makes sense on compacted clay, under heavy foot traffic from kids or dogs, or whenever you are overseeding or topdressing - the open cores are what make those treatments take. More aeration is not automatically better: coring an excellent lawn disrupts it for no gain.
Does a healthy lawn need aeration every year?▾
Not necessarily. If the lawn is healthy and shows no signs of compaction, every 2 to 3 years maintains it fine. The best reason to aerate an otherwise healthy lawn is as part of a renovation combo: core aerate, overseed, topdress lightly, fertilize, and water consistently - late August through early September is the ideal window for that in Ottawa.
Should I overseed after aerating?▾
Yes, if you want a thicker lawn. The open cores are the best seed bed you will get all year, so overseeding immediately after aeration gives far better germination than broadcasting onto untouched turf.
What about my sprinkler system?▾
Tell us you have irrigation when you book - it is recorded on the property and flagged on the crew's job sheet. Please also mark the heads visibly, since markers are what actually prevent a strike.
Can I aerate a newly seeded or sodded lawn?▾
Not yet. If sod or seed went down within the last two months the roots have not established, and aerating will tear them up. Let it root first.
