Overseeding in Windham & Greater Portland — thicken thin lawns the right way.
A thick lawn crowds out weeds, holds color longer, and recovers faster from drought.

Serving Windham, Gorham, Westbrook, Falmouth, Cumberland, Scarborough, Portland, and the surrounding Greater Portland towns.

Step 02
Aerate first, seed second
Broadcasting seed onto compacted soil rarely works. Aerating immediately before overseeding drops seed into open plugs where it contacts soil, holds moisture, and germinates at much higher rates. Most Windham and Falmouth overseeding jobs are bundled with aeration.

Fall timing wins
Late August through mid-September is the prime overseeding window across Cumberland County — warm soil for fast germination, cool air to reduce stress, and plenty of growth time before winter dormancy. Spring overseeding can work but loses to summer heat and weed pressure.
Late August through mid-September across Greater Portland — soil is still warm for germination, air is cooling, and you get 6–8 weeks of growth before winter. Spring overseeding is a fallback but generally underperforms.
How long does it take overseeded grass to fill in?+
First germination shows in 7–14 days; meaningful coverage at 4–6 weeks. The fully thickened look usually arrives the following spring.
Can I mow normally after overseeding?+
Skip mowing for the first 2–3 weeks while seedlings establish, then mow at a higher height (3.5–4") for the rest of the season. We coordinate this with your regular mowing schedule.
