Professional overseeding costs $150 to $380 for most residential lawns per LawnBySeason (about $250 for a quarter acre), or $0.10 to $0.20 per square foot per Angi.1,2 Angi’s full seeding and reseeding projects average $1,083 ($438 to $1,759) – a bigger scope than overseeding an existing lawn, see the disagreement note below.1*

Quick math: overseeding 5,000 sq ft at Angi’s $0.10 to $0.20 is $500 to $1,000 – our multiplication – while LawnBySeason’s pro table puts the same lawn at $120 to $220. The gap is scope: Angi’s rate covers full reseeding with prep, not a light overseed. For an existing lawn that just needs thickening, budget from the LawnBySeason figures.

Where they disagree: Angi’s $1,083 average comes from 1,201 verified seeding and reseeding projects – many are bare-soil or renovation jobs with heavy prep. LawnBySeason and LawnPricing price the lighter job most homeowners mean by overseeding: spreading seed over an existing lawn. Match the reference to your actual scope before comparing quotes.1,2,3
What pushes the price up
Lawn size: the main driver – LawnBySeason’s table runs from $80 to $150 up to 2,500 sq ft to $450 to $750 for a half acre.2
Prep intensity: LawnPricing’s per-foot band ($0.04 to $0.18) widens with prep – dethatching or aerating first costs more but germinates better.3
Seed variety: per Angi, the grass variety itself moves the price; premium and shade blends cost more per pound.1
Bundling: aeration plus overseeding is the classic pairing at $240 to $360 for medium properties per LawnPricing – see our lawn aeration cost guide and dethatching cost guide for the prep pieces.3

These are example projects, not quotes – lawn size, prep and seed choice set the real number. Measure the area with our square footage calculator, and for a bigger renovation compare hydroseeding cost and sod cost.

Is DIY overseeding worth it? A spreader and quality seed run $55 to $175 for a 5,000 sq ft lawn per LawnBySeason – roughly half the pro price if you already have the weekend.2
Should I aerate before overseeding? It is the standard pairing – LawnPricing prices combined jobs at $240 to $360 for medium properties, and seed-to-soil contact is what drives germination.3
Overseed, hydroseed or sod? Overseeding thickens an existing lawn; hydroseeding ($0.06 to $0.26 per sq ft) establishes new grass on bare soil; sod is instant but $1 to $2 per sq ft installed. See our hydroseeding and sod guides.
